Class: Common CUSIP: 92840M 102 Trading Symbol: VSTE 1 Item 5: Par or stated value and description of the security. A. Par or Stated Value: Common: $0.01 per share B. Common or Preferred Stock: 1. Common stock dividend, voting and preemptive rights: Dividend Rights Subject to limitations under applicable Delaware law, preferences that may apply to any outstanding shares of our preferred stock and contractual restrictions, holders of our common stock are entitled to receive dividends or other distributions ratably, when, as and if declared by the board of directors of Vistra Energy (the Board). The ability of the Board to declare dividends with respect to our common stock, however, will be subject such limitations, preferences and restrictions and the availability of sufficient funds under the Delaware General Corporation Law (DGCL) to pay such dividends. Voting Rights All shares of our common stock have identical rights and privileges. The holders of shares of our common stock are entitled to vote on all matters submitted to a vote of our stockholders, including the election of directors. On all matters to be voted on by holders of shares of our common stock, the holders will be entitled to one vote for each share of our common stock held of record, and will have no cumulative voting rights. Preemptive Rights Holders of our common stock do not have preemptive rights. 2. Preferred stock dividend, voting, conversion and liquidation rights as well as redemption or sinking fund provisions: Not applicable; no preferred shares outstanding. 3. Other material rights of common or preferred stock holders: Rights upon Liquidation In the event of a liquidation, dissolution or winding up of Vistra Energy, after the payment in full of all amounts owed to our creditors and holders of any outstanding shares of our preferred stock, the remaining assets of Vistra Energy will be distributed ratably to the holders of shares of our common stock. The rights, preferences and privileges of holders of shares of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any class or series of preferred stock which the Board may designate and issue in the future without stockholder approval. Other Rights Holders of our common stock do not have subscription, redemption or conversion rights. 4. Any provision in the issuer’s charter or by-laws that would delay, defer or prevent a change in control of the issuer: Vistra Energy's certificate of incorporation (Charter) and bylaws (Bylaws) contain a number of provisions which may have the effect of discouraging transactions that involve an actual or threatened change of control of Vistra Energy. In addition, provisions of our Charter and Bylaws may be deemed to have anti-takeover effects and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in his, her or its best interest, including those attempts that might result in a premium over the market price of the shares of our common stock held by our stockholders. 2 Staggered Board Our Charter provides for three classes of directors, each of which is to be elected on a staggered basis for a term of three years. Our Charter and Bylaws provide that the Board consists of such number of directors as determined from time to time by the vote of a majority of the total number of directors then authorized. Please see Item 11(A) for a more detailed description of the composition of our initial Board. No Written Consent of Stockholders Any action to be taken by our stockholders must be effected at a duly called annual or special meeting and may not be effected by written consent. Special Meetings of Stockholders Except as required by the DGCL or the terms of any class or series of preferred stock issued in the future, special meetings of our stockholders may be called only by (a) the Board, at any time or (b) the Chairman of the Board or the Secretary of Vistra Energy upon written request of one or more stockholders of record holding a majority of the voting power of the then-outstanding shares of our capital stock entitled to vote on the matter or matters to be brought before the proposed special meeting and complying with the notice procedures set forth in our Bylaws. Advance Notice Requirement Stockholders must provide timely notice when seeking to: • bring business before an annual meeting of stockholders; • bring business before a special meeting of stockholders (if contemplated and permitted by the notice of a special meeting), or • nominate candidates for election to the Board at an annual meeting of stockholders or at a special meeting of stockholders called for the purpose of electing one or more directors to the Board. Our Charter and Bylaws also specify requirements as to the form and content of the stockholder's notice. Issuance of Blank Check Preferred Stock Subject to limitations under applicable Delaware law, the Board is authorized to issue, from time to time and without stockholder approval, up to an aggregate of 100,000,000 shares of preferred stock in one or more classes or series and to fix the designations, powers, preferences, and relative, participating, optional or other rights, if any, and the qualifications, limitations or restrictions, if any, of the shares of each such class or series, including the dividend rights, conversion rights, voting rights, redemption rights (including sinking fund provisions), liquidation preferences and the number of shares constituting any class or series. The issuance of preferred stock with voting and conversion rights would also adversely affect the voting power of the holders of shares of our common stock, including the potential loss of voting control to others. Removal of Directors Our Charter and Bylaws provide that directors may only be removed for cause, and only upon the affirmative vote of a majority of the voting power of the capital stock outstanding and entitled to vote thereon. Section 203 of the DGCL In our Charter, we have elected not to be governed by Section 203 of the DGCL, as permitted under and pursuant to subsection (b)(3) of Section 203. Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation's outstanding voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Accordingly, we are currently not subject to any anti-takeover effects of Section 203, although no assurance can be given that we will not elect to be governed by Section 203 of the DGCL in the future. 3 Amendment of Bylaws and Charter The approval of a super-majority (66 2/3%) of the voting power of the then outstanding shares of our capital stock entitled to vote will be required to amend certain provisions of our Bylaws or to amend certain provisions of our Charter, including provisions relating to indemnification and exculpation of directors and officers and provisions relating to amendment of our Bylaws and Charter by the Board. The foregoing description of our Charter and Bylaws is qualified in its entirety by reference to the full text of these documents. The Charter and its amendment were filed as Exhibit 19(a) to the Initial Disclosure Statement filed on October 4, 2016 and Exhibit 8(a) to the Interim Report for the Quarter Ended September 30, 2016 filed on November 14, 2016, respectively. The Bylaws were filed as Exhibit 8(b) to the Interim Report for the Quarter Ended September 30, 2016 filed on November 14, 2016.

A. Business Development 1. Form of Organization: Corporation (Delaware) 2. Year that the issuer (or any predecessor) was organized: 2016 3. Fiscal year end date: December 31 4. Whether the issuer (or any predecessor) has been in bankruptcy, receivership or any similar proceeding: On April 29, 2014 (the Petition Date), EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities (collectively, the Debtors), 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). On October 3, 2016 (the Effective Date), subsidiaries of TCEH, that were Debtors in the Chapter 11 Cases (the TCEH Debtors), and certain EFH Corp. subsidiaries (the Contributed EFH Debtors) completed their reorganization under the Bankruptcy Code and emerged from the Chapter 11 Cases as subsidiaries of a newly-formed company, Vistra Energy (Emergence). On the Effective Date, Vistra Energy was spun-off from EFH Corp. in a tax-free transaction to the former first lien creditors of TCEH (Spin-Off). As a result, as of the Effective Date, Vistra Energy is a holding company for subsidiaries principally engaged in the same activities as TCEH. 5. Any material reclassification, merger, consolidation or purchase or sale of a significant amount of assets: In April 2016, Luminant purchased all of the membership equity interests in La Frontera Holdings, LLC, the indirect owner of two natural gas fueled generation facilities representing nearly 3,000 MW of capacity located in ERCOT, from a subsidiary of NextEra Energy, Inc. The facility in Forney, Texas has a capacity of 1,912 MW and the facility in Paris, Texas has a capacity of 1,076 MW. The aggregate purchase price was approximately $1.313 billion, which included the repayment of approximately $950 million of existing project financing indebtedness, plus approximately $236 million for cash and net working capital subject to final settlement. The purchase price was funded by cash-on-hand and additional borrowings under TCEH's DIP Facility totaling $1.1 billion. After completing the acquisition, TCEH repaid approximately $230 million of borrowings under TCEH's DIP Facility primarily utilizing cash acquired in the transaction. 6. Any default of the terms of any note, loan, lease or other indebtedness or financing arrangement requiring the issuer to make payments: None 7. Any change of control: None 8. Any increase of 10% or more of the same class of outstanding equity securities: Please see Item 17 9. Any past, pending or anticipated stock split, stock dividend, recapitalization, merger, acquisition, spin-off or reorganization: Please see Item 8(A)(4). Additionally, in December 2016, the board of directors of Vistra Energy approved the payment of a special cash dividend in the aggregate amount of approximately $1 billion ($2.32 per share of common stock) to holders of record of our common stock on December 19, 2016. 10. Any delisting of the issuer's securities by any securities exchange or deletion from the OTC Bulletin Board: None 5 11. Any current, past, pending or threatened legal proceedings or administrative actions either by or against the issuer that could have a material effect on the issuer's business, financial condition or operations and any current, past or pending trading suspensions by a securities regulator: Litigation relating to EPA Reviews In June 2008, the EPA issued an initial request for information to Luminant under the EPA's authority under Section 114 of the Clean Air Act (CAA). The stated purpose of the request is to obtain information necessary to determine compliance with the CAA, including New Source Review standards and air permits issued by the TCEQ for our Big Brown, Monticello and Martin Lake generation facilities. In April 2013, our Predecessor received an additional information request from the EPA under Section 114 related to the Big Brown, Martin Lake and Monticello facilities as well as an initial information request related to our Sandow 4 generation facility. In July 2012 and July 2013, the EPA sent Luminant a notice of violation alleging noncompliance with the CAA's New Source Review standards and the air permits at our Martin Lake and Big Brown generation facilities. In August 2013, the US Department of Justice, acting as the attorneys for the EPA, filed a civil enforcement lawsuit against Luminant in federal district court in Dallas, alleging violations of the CAA, including its New Source Review standards, at our Big Brown and Martin Lake generation facilities. In August 2015, the district court granted Luminant's motion to dismiss seven of the nine claims asserted by the EPA in the lawsuit. In August 2016, the EPA filed an amended complaint, eliminating one of the two remaining claims and withdrawing with prejudice a request for civil penalties in the other remaining claim. The EPA also filed a motion for entry of final judgment so that it could seek to appeal the district court's dismissal decision. In September 2016, Luminant filed a response opposing the EPA's motion for entry of final judgment. In October 2016, the district court denied the EPA's motion for entry of final judgment and agreed that the remaining claim must be fully adjudicated at the district court or withdrawn with prejudice before the EPA may appeal the dismissal decision. In January 2017, the EPA dismissed its two remaining claims with prejudice and the district court entered final judgment in our favor. In March 2017, the EPA appealed the final judgment to the Fifth Circuit Court and Luminant filed a motion in the district court to recover its attorney fees and costs. We believe that we and Luminant have complied with all requirements of the CAA and intend to vigorously defend against the remaining allegations. The lawsuit requests the maximum civil penalties available under the CAA to the government of up to $32,500 to $37,500 per day for each alleged violation, depending on the date of the alleged violation, and injunctive relief, including an order requiring the installation of best available control technology at the affected units. An adverse outcome could require substantial capital expenditures that cannot be determined at this time or retirement of the plants at issue and could possibly require the payment of substantial penalties. We cannot predict the outcome of these proceedings, including the financial effects, if any. Other Matters We are involved in various legal and administrative proceedings in the normal course of business, the ultimate resolutions of which, in the opinion of management, are not anticipated to have a material effect on our results of operations, liquidity or financial condition. B. Business of Issuer 1. The issuer's primary and secondary SIC codes: 4911 2. If the issuer has never conducted operations, is in the development stage or is currently conducting operations: The Company is currently conducting operations. 3. Whether the issuer has at any time been a shell company: The Company has not at any time been nor is currently a shell company. 4. Names of any parent, subsidiary or affiliate of the issuer, and its business purpose, its method of operation, its ownership and whether it is included in the financial statements attached to this disclosure statement: The Company conducts its business through the following subsidiaries, each of which is wholly-owned, directly or indirectly (except for Vistra Preferred Inc., which has certain preferred stockholders which are not affiliates). All of the operating results of these subsidiaries are consolidated in the Company's financial statements. See below for a list of the Company's subsidiaries: • Big Brown Power Company LLC • Brighten Energy LLC • Comanche Peak Power Company LLC 6 Sandow Power Company LLC Southwestern Electric Service Company, Inc. • Dallas Power & Light Company Inc. • Forney Pipeline, LLC • Generation SVC Company • La Frontera Holdings, LLC • Lone Star Energy Company, Inc. • Lone Star Pipeline Company, Inc. • Luminant Energy Company LLC • Luminant Energy Trading California Company • Luminant ET Services Company • Luminant Generation Company LLC • Luminant Mining Company LLC • NCA Resources Development Company LLC • Oak Grove Management Company LLC • • • Texas Electric Service Company, Inc. • Texas Energy Industries Company, Inc. • Texas Power and Light Company, Inc. • Texas Utilities Company, Inc. • Texas Utilities Electric Company, Inc. • TXU Electric Company, Inc. • TXU Energy Retail Company LLC • TXU Retail Services Company • Value Based Brands LLC • Vistra Asset Company LLC • Vistra Corporate Services Company • Vistra EP Properties Company • Vistra Finance Corp. • Vistra Intermediate Company LLC • Vistra Operations Company LLC • Vistra Preferred Inc. 5. Effect of existing or probable governmental regulations on the business: General Our businesses operate in changing market environments influenced by various state and federal legislative and regulatory initiatives regarding the restructuring of the energy industry, including competition in power generation and sale of electricity. Although we attempt to comply with changing legislative and regulatory requirements, there is a risk that we will fail to adapt to any such changes successfully or on a timely basis. Our businesses are subject to numerous state and federal laws (including PURA, the Federal Power Act, the Atomic Energy Act, the Public Utility Regulatory Policies Act of 1978, the CAA, the Energy Policy Act of 2005 and the Dodd-Frank Wall Street Reform and Consumer Protection Act), changing governmental policy and regulatory actions (including those of the PUCT, the NERC, the TRE, the RCT, the TCEQ, the FERC, the MSHA, the EPA, the NRC and the CFTC) and the rules, guidelines and protocols of ERCOT with respect to various matters, including, but not limited to, market structure and design, operation of nuclear generation facilities, construction and operation of other power generation facilities, development, operation and reclamation of lignite mines, recovery of costs and investments, decommissioning costs, market behavior, present or prospective wholesale and retail competition and environmental matters. We, along with other market participants, are subject to electricity pricing constraints and market behavior and other competition-related rules and regulations under PURA that are administered by the PUCT and ERCOT. Changes in, revisions to, or reinterpretations of, existing laws and regulations may have a material adverse effect on us. Further, in the future we could expand our business, through acquisitions or otherwise, to geographic areas outside of Texas and the ERCOT market. Such expansion would subject us to additional state regulatory requirements that could have material adverse effect on us. 7 Environmental Matters There is a concern nationally and internationally about global climate change and how greenhouse gas (GHG) emissions, such as CO2, contribute to global climate change. Over the last several years, the legislative and executive branches of the US government have considered and debated several proposals intended to address climate change using different approaches, including a cap on carbon emissions with emitters allowed to trade unused emission allowances (cap-and-trade), a tax on carbon or GHG emissions, incentives for the development of low-carbon technology and federal renewable portfolio standards. The EPA has also finalized regulations under the CAA to limit CO2 emissions from existing generating units, referred to as the Clean Power Plan. While currently the subject of a legal challenge, if implemented as finalized, the Clean Power Plan would require the closure of a significant number of coal-fueled electric generating units nationwide and in Texas. In addition, a number of federal court cases have been filed in recent years asserting damage claims related to GHG emissions, and the results in those proceedings could establish adverse precedent that might apply to companies (including us) that produce GHG emissions. We could be materially and adversely affected if new federal and/or state legislation or regulations are adopted to address global climate change, if the Clean Power Plan is implemented as finalized or if we are subject to lawsuits for alleged damage to persons or property resulting from GHG emissions. Greenhouse Gas Emissions — In August 2015, the EPA finalized rules to address GHG emissions from new, modified and reconstructed and existing electricity generation units, referred to as the Clean Power Plan. The rule for existing facilities would establish state-specific emissions rate goals to reduce nationwide CO2 emissions related to affected units by over 30% from 2012 emission levels by 2030. A number of parties, including Luminant, filed petitions for review in the US Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) for the rule for new, modified and reconstructed plants. In addition, a number of petitions for review of the rule for existing plants were filed in the D.C. Circuit Court by various parties and groups, including challenges from twenty-seven different states opposed to the rule as well as those from, among others, certain power generating companies, various business groups and some labor unions. Luminant also filed its own petition for review. In January 2016, a coalition of states, industry (including Luminant) and other parties filed applications with the US Supreme Court (Supreme Court) asking that the Supreme Court stay the rule while the D.C. Circuit Court reviews the legality of the rule for existing plants. In February 2016, the Supreme Court stayed the rule pending the conclusion of legal challenges on the rule before the D.C. Circuit Court and until the Supreme Court disposes of any subsequent petition for review. Oral argument on the merits of the legal challenges to the rule were heard in September 2016 before the entire D.C. Circuit Court. In March 2017, President Trump issued an Executive Order entitled Promoting Energy Independence and Economic Growth (Order). The Order covers a number of matters, including the Clean Power Plan. Among other provisions, the Order directs the EPA to review the Clean Power Plan and, if appropriate, suspend, revise or rescind the rules on existing and new, modified and reconstructed generating units. In addition, the Department of Justice has filed motions seeking to abate those cases until the EPA concludes its review of the rules, including any new rulemaking that results from that review. While we cannot predict the outcome of these rulemakings and related legal proceedings, or estimate a range of reasonably probable costs, if the rules are ultimately implemented or upheld as they were issued, they could have a material impact on our results of operations, liquidity or financial condition. In August 2015, the EPA proposed model rules and federal plan requirements for states to consider as they develop state plans to comply with the rules for GHG emissions. A federal plan would then be finalized for a state if a state fails to submit a state plan by the deadlines established in the Clean Power Plan for existing plants or if the EPA disapproves a submitted state plan. Luminant filed comments on the federal plan proposal and model rules in January 2016. The Executive Order issued in March 2017, directed the EPA to review this proposed rule for consistency with the policies in the Order and, if appropriate, to revise or withdraw the proposed rule. While we cannot predict the timing or outcome of this rulemaking and related legal proceedings, or estimate a range of reasonably possible costs, they could have a material impact on our results of operations, liquidity or financial condition. Cross-State Air Pollution Rule (CSAPR) — In July 2011, the EPA issued the CSAPR, compliance with which would have required significant additional reductions of SO2 and NOx emissions from our fossil fueled generation units. In February 2012, the EPA released a final rule (Final Revisions) and a proposed rule revising certain aspects of the CSAPR, including increases in the emissions budgets for Texas and our generation assets as compared to the July 2011 version of the rule. In June 2012, the EPA finalized the proposed rule (Second Revised Rule). 8 The CSAPR became effective January 1, 2015. In July 2015, following a remand of the case from the Supreme Court to consider further legal challenges, the D.C. Circuit Court unanimously ruled in favor of Luminant and other petitioners, holding that the CSAPR emissions budgets over-controlled Texas and other states. The D.C. Circuit Court remanded those states' budgets to the EPA for prompt reconsideration. While Luminant planned to participate in the EPA's reconsideration process to develop increased budgets for the 1997 ozone standard that do not over-control Texas, the EPA instead responded to the remand by proposing a new rulemaking that created new NOX ozone season budgets for the 2008 ozone standard without addressing the over-controlling budgets for the 1997 standard. Comments on the EPA's proposal were submitted by Luminant in February 2016. In August 2016, the EPA disapproved Texas's 2008 ozone State Implementation Plan (SIP) submittal and imposed a Federal Implementation Plan (FIP) in its place in October 2016. Texas filed a petition in the Fifth Circuit Court challenging the SIP disapproval and Luminant has intervened in support of Texas's challenge. The State of Texas and Luminant have also both filed challenges in the D.C. Circuit Court challenging the EPA's FIP and those cases are currently pending before that court. With respect to Texas's SO2 emission budgets, in June 2016, the EPA issued a memorandum describing the EPA's proposed approach for responding to the D.C. Circuit Court's remand for reconsideration of the CSAPR SO2 emission budgets for Texas and three other states that had been remanded to the EPA by the D.C. Circuit Court. In the memorandum, the EPA stated that those four states could either voluntarily participate in the CSAPR by submitting a SIP revision adopting the SO2 budgets that had been previously held invalid by the D.C. Circuit Court and the current annual NOx budgets or, if the state chooses not to participate in the CSAPR, the EPA could withdraw the CSAPR FIP by the fall of 2016 for those states and address any interstate transport and regional haze obligations on a state-by- state basis. Texas has not indicated that it intends to adopt the over-controlling budgets and, in November 2016, the EPA proposed to withdraw the CSAPR FIP for Texas. Because the EPA has not finalized its proposal to remove Texas from the annual CSAPR programs, these programs will continue to apply to Texas and Texas sources. At this time, the EPA has not populated the allowance accounts for Texas sources with 2017 annual CSAPR program allowances. While we cannot predict the outcome of future proceedings related to the CSAPR, including the EPA's recent actions concerning the CSAPR annual emissions budgets for affected states and participating in the CSAPR program, based upon our current operating plans we do not believe that the CSAPR itself will cause any material operational, financial or compliance issues to our business or require us to incur any material compliance costs. Regional Haze — Reasonable Progress and Long-Term Strategies — The Regional Haze Program of the CAA establishes "as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I federal areas, like national parks, which impairment results from man-made pollution." There are two components to the Regional Haze Program. First, states must establish goals for reasonable progress for Class I federal areas within the state and establish long-term strategies to reach those goals and to assist Class I federal areas in neighboring states to achieve reasonable progress set by those states towards a goal of natural visibility by 2064. In February 2009, the TCEQ submitted a SIP concerning regional haze (Regional Haze SIP) to the EPA. In December 2011, the EPA proposed a limited disapproval of the Regional Haze SIP due to its reliance on the Clean Air Interstate Rule (CAIR) instead of the EPA's replacement CSAPR program that the EPA proposed in July 2011. In August 2012, Luminant filed a petition for review in the US Court of Appeals for the Fifth Circuit (Fifth Circuit Court) challenging the EPA's limited disapproval of the Regional Haze SIP on the grounds that the CAIR continued in effect pending the D.C. Circuit Court's decision in the CSAPR litigation. In September 2012, Luminant filed a petition to intervene in a case filed by industry groups and other states and private parties in the D.C. Circuit Court challenging the EPA's limited disapproval and issuance of a FIP regarding the regional haze best available retrofit technology (BART) program. The Fifth Circuit Court case has since been transferred to the D.C. Circuit Court and consolidated with other pending BART program regional haze appeals. Briefing in the D.C. Circuit Court was completed in March 2017. In June 2014, the EPA issued requests for information under Section 114 of the CAA to Luminant and other generators in Texas related to the reasonable progress program. After releasing a proposed rule in November 2014 and receiving comments from a number of parties, including Luminant and the State of Texas in April 2015, the EPA released a final rule in January 2016 approving in part and disapproving in part Texas' SIP for Regional Haze and issuing a FIP for Regional Haze. In the rule, the EPA asserts that the Texas SIP does not show reasonable progress in improving visibility for two areas in Texas and that its long-term strategy fails to make emission reductions needed to achieve reasonable progress in improving visibility in the Wichita Mountains of Oklahoma. The EPA's proposed emission limits in the FIP assume additional control equipment for specific lignite/coal-fueled generation units across Texas, including new flue gas desulfurization systems (scrubbers) at seven electricity generating units and upgrades to existing scrubbers at seven electricity generating units. Specifically, for Luminant, the EPA's FIP is based on new scrubbers at Big Brown Units 1 and 2 and Monticello Units 1 and 2 and scrubber upgrades at Martin Lake Units 1, 2 and 3, Monticello Unit 3 and Sandow Unit 4. Luminant is continuing to evaluate the requirements and potential financial and operational impacts of the rule, but new scrubbers at the Big Brown and Monticello units necessary to achieve the emission limits required by the FIP (if those limits are possible to attain), along with the existence of low wholesale electricity prices in ERCOT, would likely challenge the long-term economic viability of those units. Under the terms of the rule, the scrubber upgrades will be required by February 2019, and the new scrubbers will be required by February 2021. 9 In March 2016, Luminant and a number of other parties, including the State of Texas, filed petitions for review in the Fifth Circuit Court challenging the FIP's Texas requirements. Luminant and other parties also filed motions to stay the FIP while the court reviews the legality of the EPA's action. In July 2016, the Fifth Circuit Court denied the EPA's motion to dismiss Luminant's challenge to the FIP and denied the EPA's motion to transfer the challenges Luminant, the other industry petitioners and the State of Texas filed to the D.C. Circuit Court. In addition, the Fifth Circuit Court granted the motions to stay filed by Luminant, the other industry petitioners and the State of Texas pending final review of the petitions for review. The case was abated until the end of November 2016 in order to allow the parties to pursue settlement discussions. Settlement discussions were unsuccessful, and in December 2016 the EPA filed a motion seeking a voluntary remand of the rule back to the EPA for further consideration of Luminant's pending request for administrative reconsideration. Luminant and some of the other petitioners filed a response opposing the EPA's motion to remand and filed a cross motion for vacatur of the rule in December 2016. In March 2017, the Fifth Circuit Court remanded the rule back to the EPA for reconsideration in light of the Court's prior determination that we and the other petitioners demonstrated a substantial likelihood that the EPA exceeded its statutory authority and acted arbitrarily and capriciously, but the Court denied all of the other pending motions. The stay of the rule (and the emission control requirements) remains in effect. In addition, the Fifth Circuit Court denied the EPA's motion to lift the stay as to parts of the rule implicated in the EPA's subsequent BART proposal and the Court is retaining jurisdiction of the case and requiring the EPA to file status reports on its reconsideration every 15 days. While we cannot predict the outcome of the rulemaking and legal proceedings, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Regional Haze — Best Available Retrofit Technology — The second part of the Regional Haze Program subjects electricity generation units built between 1962 and 1977, to BART standards designed to improve visibility if such units cause or contribute to impairment of visibility in a federal class I area. BART reductions of SO2 and NOX are required either on a unit-by-unit basis or are deemed satisfied by state participation in an EPA-approved regional trading program such as the CSAPR. In response to a lawsuit by environmental groups, the D.C. Circuit Court issued a consent decree in March 2012 that required the EPA to propose a decision on the Regional Haze SIP by May 2012 and finalize that decision by November 2012. The consent decree requires a FIP for any provisions that the EPA disapproves. The D.C. Circuit Court has amended the consent decree several times to extend the dates for the EPA to propose and finalize a decision on the Regional Haze SIP. The consent decree was modified in December 2015 to extend the deadline for the EPA to finalize action on the determination and adoption of requirements for BART for electricity generation. Under the amended consent decree, the EPA had until December 2016 to propose, and has until September 2017 to finalize, a FIP for BART for Texas electricity generation sources if the EPA determines that BART requirements have not been met. The EPA issued its proposed BART FIP for Texas in December 2016. The EPA's proposed emission limits assume additional control equipment for specific lignite/coal-fueled generation units across Texas, including new flue gas desulfurization systems (scrubbers) at 12 electric generation units and upgrades to existing scrubbers at four electric generation units. Specifically, for Luminant, the EPA's emission limitations are based on new scrubbers at Big Brown Units 1 and 2 and Monticello Units 1 and 2 and scrubber upgrades at Martin Lake Units 1, 2 and 3 and Monticello Unit 3. Luminant is continuing to evaluate the requirements and potential financial and operational impacts of the proposed rule, but new scrubbers at the Big Brown and Monticello units necessary to achieve the emission limits required by the FIP (if those limits are possible to attain), along with the existence of low wholesale power prices in ERCOT, would likely challenge the long-term economic viability of those units. Under the terms of the rule, the scrubber upgrades will be required within three years of the effective date of the final rule and the new scrubbers will be required within five years of the effective date of the final rule. We anticipate submitting comments on the proposed FIP when those are due in May 2017. While we cannot predict the outcome of the rulemaking and potential legal proceedings, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Intersection of the CSAPR and Regional Haze Programs — Historically the EPA has considered compliance with a regional trading program, such as the CSAPR, as satisfying a state's obligations under the BART portion of the Regional Haze Program. However, in the reasonable progress FIP, the EPA diverged from this approach and did not treat Texas' compliance with the CSAPR as satisfying its obligations under the BART portion of the Regional Haze Program. The EPA concluded that it would not be appropriate to finalize that determination given the remand of the CSAPR budgets. As described above, the EPA has now proposed to remove Texas from the annual CSAPR trading programs. If Texas were in the CSAPR annual trading programs, the EPA would have no basis for its BART FIP because it has made a determination for Texas and all other states that participate in the CSAPR annual trading programs that such participation satisfies their BART obligations. We do not believe that EPA's proposal to remove Texas from the CSAPR annual trading programs satisfies the D.C. Circuit Court's mandate to the EPA to develop non-over- controlling budgets for Texas and we submitted comments on the EPA's proposed rule to remove Texas from the CSAPR annual trading programs. While we cannot predict the outcome of these matters, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. 10 Affirmative Defenses During Malfunctions — In February 2013, in response to a petition for rulemaking filed by the Sierra Club, the EPA proposed a rule requiring certain states to replace SIP exemptions for excess emissions during malfunctions with an affirmative defense. Texas was not included in that original proposal since it already had an EPA-approved affirmative defense provision in its SIP that was found to be lawful by the Fifth Circuit Court in 2013. In 2014, as a result of a D.C. Circuit Court decision striking down an affirmative defense in another EPA rule, the EPA revised its 2013 proposal to extend the EPA's proposed findings of inadequacy to states that have affirmative defense provisions, including Texas. The EPA's revised proposal would require Texas to remove or replace its EPA-approved affirmative defense provisions for excess emissions during startup, shutdown and maintenance events. In May 2015, the EPA finalized the proposal. In June 2015, Luminant filed a petition for review in the Fifth Circuit Court challenging certain aspects of the EPA's final rule as they apply to the Texas SIP. The State of Texas and other parties have also filed similar petitions in the Fifth Circuit Court. In August 2015, the Fifth Circuit Court transferred the petitions that Luminant and other parties filed to the D.C. Circuit Court, and in October 2015 the petitions were consolidated with the pending petitions challenging the EPA's action in the D.C. Circuit Court. Briefing in the D.C. Circuit Court on the challenges was completed in October 2016 and oral argument is set for May 2017. We cannot predict the timing or outcome of this proceeding, or estimate a range of reasonably possible costs, but implementation of the rule as finalized may have a material impact on our results of operations, liquidity or financial condition. SO2 Designations for Texas — In February 2016, the EPA notified Texas of the EPA's preliminary intention to designate nonattainment areas for counties surrounding our Big Brown, Monticello and Martin Lake generation plants based on modeling data submitted to the EPA by the Sierra Club. Such designation would potentially require the implementation of various controls or other requirements to demonstrate attainment. Luminant submitted comments challenging the use of modeling data rather than data from actual air quality monitoring equipment. In November 2016, the EPA finalized its proposed designations for Texas including finalizing the nonattainment designations for the areas referenced above. In doing so, the EPA ignored contradictory modeling that we submitted with our comments. The final designation mandates would be for Texas to begin the multi-year process to evaluate what potential emission controls or operational changes, if any, may be necessary to demonstrate attainment. In February 2017, the State of Texas and Luminant filed challenges to the nonattainment designations in the Fifth Circuit Court and protective petitions in the D.C. Circuit Court. In March 2017, the EPA filed a motion to transfer or dismiss our Fifth Circuit Court petition. In addition, Luminant has filed a request with the EPA to reconsider the rule and immediately stay its effective date. While we cannot predict the outcome of this matter, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Stream Protection Rule In July 2015, the Office of Surface Mining (OSM) proposed a Stream Protection Rule that represents significant changes to surface mining regulations under the Surface Mining Control and Reclamation Act (SMCRA) program. The rule proposes to prevent or minimize impacts to surface water and groundwater from coal mining. In October 2015, we filed comments on the proposed rule. In December 2016, the OSM issued a final Stream Protection Rule that became effective in January 2017. Thereafter, the US Congress enacted a resolution under the Congressional Review Act that repealed the Stream Protection Rule and President Trump signed that resolution in February 2017. General Permit Applications and Renewals (Generally) We are required to obtain, and to comply with, numerous permits and licenses from federal, state and local governmental agencies. The process of obtaining and renewing necessary permits and licenses can be lengthy and complex and can sometimes result in the establishment of conditions that make the project or activity for which the permit or license was sought unprofitable or otherwise unattractive. In addition, such permits or licenses may be subject to denial, revocation or modification under various circumstances. Failure to obtain or comply with the conditions of permits or licenses, or failure to comply with applicable laws or regulations, may result in the delay or temporary suspension of our operations and electricity sales or the curtailment of our delivery of electricity to our customers and may subject us to penalties and other sanctions. Although various regulators routinely renew existing permits and licenses, renewal of our existing permits or licenses could be denied or jeopardized by various factors, including (a) failure to provide adequate financial assurance for closure, (b) failure to comply with environmental, health and safety laws and regulations or permit conditions, (c) local community, political or other opposition and (d) executive, legislative or regulatory action. 11 Our inability to procure and comply with the permits and licenses required for our operations, or the cost to us of such procurement or compliance, could have a material adverse effect on us. In addition, new environmental legislation or regulations, if enacted, or changed interpretations of existing laws, may cause routine maintenance activities at our facilities to need to be changed in order to avoid violating applicable laws and regulations or elicit claims that historical routine maintenance activities at our facilities violated applicable laws and regulations. In addition to the possible imposition of fines in the case of any such violations, we may be required to undertake significant capital investments in emissions control technology and obtain additional operating permits or licenses, which could have a material adverse effect on us. Comanche Peak Nuclear Generation Facility The NRC may modify, suspend or revoke licenses and impose civil penalties for failure to comply with the Atomic Energy Act, the regulations under it or the terms of the licenses of nuclear generation facilities. Unless extended, as to which no assurance can be given, the NRC operating licenses for the two licensed operating units at the Comanche Peak Facility will expire in 2030 and 2033, respectively. Changes in regulations by the NRC, including potential regulation as a result of the NRC's ongoing analysis and response to the effects of the natural disaster on nuclear generation facilities in Japan in 2011, as well as any extension of our operating licenses, could require a substantial increase in capital expenditures or result in increased operating or decommissioning costs. Luminant's Mining Permits The RCT, which exercises broad authority to regulate mining reclamation activity, reviews on an ongoing basis whether Luminant is compliant with RCT rules and regulations and whether it has met all of the requirements of its mining permits. Any new rules and regulations adopted by the RCT or the OSM, which also regulates mining activity nationwide, or any changes in the interpretation of existing rules and regulations, could result in higher compliance costs or otherwise adversely affect our financial condition or cause a revocation of a mining permit. Any revocation of a mining permit would mean that Luminant would no longer be allowed to mine lignite at the applicable mine to serve its generation facilities. Any such event could have a material adverse effect on us. REP Certification The PUCT may at any time initiate an investigation into whether our retail operation complies with certain PUCT rules and whether we have met all of the requirements for REP certification, including financial requirements. Any removal or revocation of an REP certification would mean that we would no longer be allowed to provide electricity service to retail customers. Such decertification could have a material adverse effect on us. Moreover, any capital or other expenditures that we are required by the PUCT to undertake in order to achieve or maintain any such compliance could also have a material adverse effect on us. 6. Estimate of the amount spent during each of the last two fiscal years on research and development activities, and, if applicable, the extent to which the cost of such activities are borne directly by customers: The amount spent during each of the last two fiscal years on research and development activities is immaterial to the Company as a whole and the cost of such activities are not borne directly by customers. 7. Costs and effects of compliance with environmental laws (federal, state and local): Please see Item 8(B)(5) 8. Number of total employees and number of full-time employees: Employees as of December 31, 2016 Total (a) 4,435 Full-Time 4,427 __________ (a) Includes 1,786 employees under collective bargaining agreements. 12 Item 9: Nature of products or services offered: Please see Items 8(A) and 8(B) Vistra Energy is an energy company operating an integrated power business in Texas, which includes TXU Energy and Luminant. Our primary operations consist of electricity solutions, including retail sales of electricity and related products to end users, power generation (including operations and maintenance and outage and project management) and sales of electricity in the wholesale marketplace, asset optimization and commodity risk management performed on an integrated basis for our retail and wholesale positions, and fuel logistics and management. These operations work together on an integrated basis, which allows us to realize efficiencies and alignment in all aspects of the electricity generation and sales operation. We operate solely in the growing ERCOT electricity market, which we view as one of the most attractive power markets in the US. As described in more detail below, ERCOT is an ISO that manages the flow of electricity to approximately 24 million Texas customers, representing approximately 90% of the state's load, and spanning approximately 75% of its geography, as of December 31, 2016. Retail Texas has one of the fastest growing populations of any state in the US and has a diverse economy, which has resulted in a significant and growing competitive retail electricity market. We are an active participant in the competitive ERCOT market and continue to be a market leader, which we believe is driven by, among other things, having one of the lowest customer complaint rates, according to the PUCT, having an integrated power generation operation that allows us to efficiently obtain the electricity needed to serve our customers at the lowest cost, and leveraging the experience of our wholesale commodity risk management operations to optimize our cost to procure electricity and other products on behalf of our customers. We provided electricity to approximately 24% and 18% of the residential and commercial customers in ERCOT, respectively, as of December 31, 2016. We believe we have differentiated ourselves by providing a distinctive customer experience predicated on delivering reliable and innovative power products and solutions to our customers, such as our Free Nights and Free Weekends residential plans, MyEnergy DashboardSM, TXU Energy's iThermostat product and mobile solutions, the TXU Energy Rewards program, the TXU Energy Green UPSM renewable energy credit program and a diverse set of solar options, which give our customers choice, convenience and control over how and when they use electricity and related services. We competitively market our retail electricity and related services to acquire, serve and retain both retail and wholesale customers. Our wholesale customers represent a cross section of industrial users, other competitive retail electric providers, municipalities, cooperatives and other end-users of electricity. We believe we are able to better serve our retail customers through our unique affiliation with our wholesale commodity risk management personnel who are able to structure products and contracts in a way that offers significant value compared to stand- alone retail electric providers. Additionally, our generation business protects our retail business from power price volatility, by allowing it to bypass bid-ask spread in the market (particularly for illiquid products and time periods), which results in significantly lower collateral costs for our retail business as compared to other, non-integrated retail electric providers. Moreover, our retail business reduces, to some extent, the exposure of our wholesale generation business to wholesale power price volatility. This is because the retail load requirements of our retail operations (primarily TXU Energy) provide a natural offset to the length of Luminant's generation portfolio thereby reducing the exposure to wholesale power price volatility as compared to a non-integrated pure-play independent power producer (IPP). 13 Generation Our power generation fleet is diverse and flexible in terms of dispatch characteristics as our fleet includes baseload, intermediate/load-following and peaking generation. Our wholesale commodity risk management business is responsible for dispatching our generation fleet in response to market needs after implementing portfolio optimization strategies, thus linking and integrating the generation fleet production with our retail customer and wholesale sales opportunities. Market demand, also known as load, faced by an electric power system such as ERCOT varies from moment to moment as a result of changes in business and residential demand, much of which is driven by weather. Unlike most other commodities, the production and consumption of electricity must remain balanced on an instantaneous basis. There is a certain baseline demand for electricity across an electric power system that occurs throughout the day, which is typically satisfied by baseload generating units with low variable operating costs. Baseload generating units can also increase output to satisfy certain incremental demand and reduce output when demand is unusually low. Intermediate/load-following generating units, which can more efficiently change their output to satisfy increases in demand, typically satisfy a large proportion of changes in intraday load as they respond to daily increases in demand or unexpected changes in supply created by reduced generation from renewable resources or other generator outages. Peak daily loads are typically satisfied by peaking units. Peaking units are typically the most expensive to operate, but they can quickly start up and shut down to meet brief peaks in demand. In general, baseload units, intermediate/load-following units and peaking units are dispatched into the ERCOT grid in order from lowest to highest variable cost. Price formation in ERCOT, as with other competitive power markets in the US, is typically based on the highest variable cost unit that clears the market to satisfy system demand at a given point in time. Our wholesale commodity risk management business also procures renewable energy credits from renewable generation to support our electricity sales to wholesale and retail customers to satisfy the increasing demand for renewable resources from such customers. As of December 31, 2016, we had long-term power purchase agreements to annually procure 390 MW of renewable energy. These renewable generation sources deliver electricity when conditions make them available, and, when on-line, they generally compete with baseload units. Because they cannot be relied upon to meet demand continuously due to their dependence on weather and time of day, these generation sources are categorized as non-dispatchable and create the need for intermediate/ load-following resources to respond to changes in their output. Our generation resources, which represented approximately 17% of the installed generation capacity in ERCOT as of December 31, 2016, allow us to annually generate, procure and sell approximately 75-85 TWh of electricity to wholesale and retail customers from nuclear, natural gas, lignite, coal and renewable generation resources. The ERCOT Market ERCOT is an ISO that manages the flow of electricity from approximately 78,000 MW of capacity to 24 million Texas customers, representing 90% of the state's electric load and spanning approximately 75% of its geography, as of December 31, 2016. ERCOT is a highly competitive wholesale electricity market with historically above-average demand growth, limited import and export capacity and high wholesale price caps, and is the seventh-largest power market in the world, according to the US Energy Information Administration (EIA). Population growth in Texas is currently expanding at well above the national average rate, with a growth rate of 8.8% between July 2010 and July 2016, more than double the US population growth rate of 3.9% during the same period, according to the U.S. Census Bureau. ERCOT accounts for approximately 32% of the competitively served retail load in the US and residential consumers in the ERCOT market consume approximately 32% more electricity than the average US residential consumer according to the EIA. Total ERCOT power demand has grown at a compounded annual growth rate of approximately 1.5% from 2005 through 2014, compared to a range of -0.6% to 0.8% in other US markets, according to ERCOT and the EIA, respectively. ERCOT was formed in 1970 and became the first ISO in the US in September 1996. As an energy-only market, ERCOT's market design is distinct from other competitive electricity markets in the United States. Other markets maintain a minimum reserve margin through regulated planning, resource adequacy requirements and/or capacity markets. In contrast, ERCOT's resource adequacy is predominately dependent on free-market processes and energy-market price signals. On June 1, 2014, ERCOT implemented the Operating Reserve Demand Curve (ORDC), pursuant to which wholesale electricity prices in the real-time electricity market increase automatically as available operating reserves decrease below defined threshold levels, creating a price adder. When operating reserves drop to 2,000 MW or less, the ORDC automatically adjusts power prices to the established value of lost load (VOLL), which is set at $9,000/MWh. Because ERCOT has limited excess generation capacity to meet high demand days due to its minimal import capacity, and peaking facilities have high operating costs, the marginal price of supply rapidly increases during periods of high demand. Historically, elevated temperatures in the summer months have driven high electricity demand in ERCOT. Many generators benefit from these sporadic periods of "scarcity pricing" in which real-time power prices may increase significantly, up to the current $9,000/MWh price cap. 14 Transactions in ERCOT take place in two key markets: the day-ahead market and the real-time market. The day-ahead market is a voluntary, forward electricity market conducted the day before each operating day in which generators and purchasers of electricity may bid for one or more hours of electricity supply or consumption. The real-time market is a spot market in which electricity may be sold in five-minute intervals. The day-ahead market provides market participants with visibility into where prices are expected to clear, and the prices are not impacted by subsequent events. Conversely, the real-time market exposes purchasers to the risk of transient operational events and price spikes. These two markets allow market participants to manage their risk profile by adjusting their participation in each market. In addition, ERCOT uses ancillary services to maintain system reliability, including regulation service - up, regulation service - down, responsive reserve service and non-spinning reserve service. Regulation service up and down are used to balance the grid in a near-instantaneous fashion when supply and demand fluctuate due to a variety of factors, such as weather, generation outages, renewable production intermittency and transmission outages. Non-spinning reserves are used by ERCOT to recover from system disturbances and when there is a temporary shortage of capacity available to be dispatched. Responsive reserves are used by ERCOT when the grid is at, near or recovering from a state of emergency due to inadequate generation. Because ERCOT has one of the highest concentrations of wind capacity generation among US markets, the ERCOT market is more susceptible to fluctuations in wholesale electricity supply due to intermittent wind production, making ERCOT more vulnerable to periods of generation scarcity. Seasonality The demand for and market prices of electricity and natural gas are affected by weather. As a result, our operating results may fluctuate on a seasonal basis, and more severe weather conditions such as heat waves or extreme winter weather may make such fluctuations more pronounced. The pattern of this fluctuation may change depending on, among other things, the retail load served and the terms of contracts to purchase or sell electricity. Competition Competition in ERCOT, as in other electricity markets, is impacted by electricity and fuel prices, congestion along the power grid, subsidies provided by state and federal governments for new generation facilities, new market entrants, construction of new generating assets, technological advances in power generation, the actions of environmental and other regulatory authorities and other factors. We primarily compete with other electricity generators and retailers based on our ability to generate electric supply, and market and sell electricity, at competitive prices and to efficiently utilize transportation from third-party pipelines and transmission from electric utilities and ISOs to deliver electricity to end-users. Competitors in the generation and retail power markets in which we participate include industrial companies, electric cooperative- and municipal utility-owned generators, competitive subsidiaries of regulated utilities, IPPs, REPs and other energy marketers. Brand Value Our TXU EnergyTM brand, which has been used to sell electricity in the competitive retail electricity market in Texas for approximately 15 years, is registered and protected by trademark law and is the only intellectual property asset that we own. We value the TXU EnergyTM brand at approximately $1.2 billion. 15 Item 10: Nature and extent of the issuer's facilities: Luminant's generation fleet consists of 50 power generation units, all of which are wholly owned and operate within the ERCOT electricity market, with the location, fuel types, dispatch characteristics and total installed nameplate generation capacity for each generation facility shown in the table below: Name Location (all in the state of Texas) Comanche Peak Somervell County Robertson County Milam County Freestone County Rusk County Titus County Oak Grove Sandow Big Brown Martin Lake Monticello Forney Lamar Fuel Type Nuclear Lignite Lignite Dispatch Type Baseload Baseload Baseload Lignite/Coal Lignite/Coal Lignite/Coal Intermediate/Load Following Intermediate/Load Following Intermediate/Load Following Kaufman County Natural Gas (CCGT) Intermediate/Load Following Lamar County Natural Gas (CCGT) Intermediate/Load Following Morgan Creek Mitchell County Natural Gas (CT) Permian Basin Ward County DeCordova Hood County Natural Gas (CT) Natural Gas (CT) Lake Hubbard Dallas County Natural Gas (Steam) Stryker Creek Cherokee County Natural Gas (Steam) Young County Natural Gas (Steam) Henderson County Natural Gas (Steam) Graham Trinidad Total Fuel Supply Peaking Peaking Peaking Peaking Peaking Peaking Peaking Installed Nameplate Generation Capacity (MW) Number of Units 2,300 1,600 1,137 1,150 2,250 1,880 1,912 1,076 390 325 260 921 685 630 244 2 2 2 2 3 3 8 6 6 5 4 2 2 2 1 16,760 50 Nuclear — We operate two nuclear generation units at the Comanche Peak plant site, each of which is designed for a capacity of 1,150 MW. Comanche Peak Unit 1 and Unit 2 went into commercial operation in 1990 and 1993, respectively, and are generally operated at full capacity. Refueling (nuclear fuel assembly replacement) outages for each unit are scheduled to occur every eighteen months during the spring or fall off-peak demand periods. Every three years, the refueling cycle results in the refueling of both units during the same year, the latest of which occurred in 2014. We also expect to refuel both units during 2017. While one unit is undergoing a refueling outage, the remaining unit is intended to operate at full capacity. During a refueling outage, other maintenance, modification and testing activities are completed that cannot be accomplished when the unit is in operation. Over the last three years the refueling outage period per unit has ranged from 29 to 54 days. The Comanche Peak facility operated at a capacity factor of 105.7%, 99.0% and 92.5% in 2016, 2015 and 2014, respectively. We have contracts in place for all our nuclear fuel requirements for 2017. We have contracts in place for the majority of our nuclear fuel requirements through 2018. As part of the Chapter 11 Cases, we terminated or renegotiated certain nuclear fuel contracts to provide for better economic or operational terms and conditions. We do not anticipate any significant difficulties in acquiring uranium and contracting for associated conversion, enrichment and fabrication services in the foreseeable future. The nuclear industry has developed ways to store used nuclear fuel on site at nuclear generation facilities, primarily through the use of dry cask storage, since there are no facilities for reprocessing or disposal of used nuclear fuel currently in operation in the US. Luminant stores its used nuclear fuel on-site in storage pools or dry cask storage facilities and believes its on-site used nuclear fuel storage capability is sufficient for the foreseeable future. Coal/Lignite — Our lignite/coal fueled generation fleet capacity totals 8,017 MW. Maintenance outages at these units are scheduled during the spring or fall off-peak demand periods. Over the last three years, the total annual scheduled and unscheduled outages per unit averaged approximately 33 days in duration. Our lignite/coal fueled generation fleet operated at a capacity factor of 77.1%, 59.5% and 69.6% in 2016, 2015 and 2014, respectively. This performance reflects increased economic backdown of the units and the seasonal suspension of certain units due to the persistent low wholesale power price environment in ERCOT. 16 We satisfy all of our fuel requirements at the Oak Grove and Sandow generation facilities with lignite that we mine. We meet our fuel requirements for the Big Brown and Martin Lake generation units by blending lignite we mine with coal purchased from multiple suppliers under contracts of various lengths and transported from the Powder River Basin to our generation plants by railcar. All fuel requirements for our Monticello generation units are met with coal supplied from the Powder River Basin. In 2016, approximately 39% of the fuel used at the Big Brown, Monticello and Martin Lake generation facilities and 65% of the fuel used at all of our lignite/coal fueled generation facilities was supplied from surface minable lignite reserves dedicated to our generation plants, which are located adjacent to the reserves. As a result of projected mining development costs, current economic forecasts and regulatory uncertainty, in 2014, Luminant decided to transition the fuel plans at its Big Brown and Monticello generation facilities to be fully fueled with coal from the Powder River Basin. As a result, it plans to discontinue lignite mining operations at these sites once mining and reclamation of current mine sites is complete. The majority of reclamation activities at these facilities are expected to be completed by the end of 2020 unless economic forecasts and increased regulatory certainty justify additional mine development. Natural Gas — Our natural gas-fueled generation fleet capacity totals 6,443 MW. In April 2016, we acquired La Frontera Holdings, LLC the indirect owner of two combined-cycle gas turbine (CCGT) natural gas fueled generation facilities located in ERCOT. The facility in Forney, Texas (8 units) has a capacity of 1,912 MW and the facility in Paris, Texas (6 units) has a capacity of 1,076 MW. The acquisition diversified our fuel mix and increased the dispatch flexibility in our fleet. We also operate combustion turbine (CT) facilities at Morgan Creek (6 units), Permian Basin (5 units), DeCordova (4 units) plant sites and steam facilities at Lake Hubbard (2 units), Stryker Creek (2 units), Graham (2 units) and Trinidad (1 unit) plant sites. The CT and steam plants are peaking units which provide us the ability to meet increased demand from our retail customers during high market price intervals with available generation capacity and provide other wholesale opportunities. We satisfy our fuel requirements at these facilities through a combination of spot market and near-term purchase contracts. Additionally, we have near-term natural gas transportation agreements in place for all of our sites to ensure reliable fuel supply. 17 Part D: Management Structure and Financial Information Item 11: Name of chief executive officer, members of the board of directors, as well as control persons.

Morgan, Burke and Holden and Ms. Kirby, Graziano and Moore do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements (see Item 18. Material Contracts). 2016 Incentive Plan The Board adopted the 2016 Omnibus Incentive Plan (the 2016 Incentive Plan), effective as of the Effective Date, under which an aggregate of 22,500,000 shares of our common stock were reserved for issuance as equity-based awards to our non- employee directors, employees, and certain other persons. The Board or any committee duly authorized by the Board (the Committee) will administer the 2016 Incentive Plan and has broad authority under the 2016 Incentive Plan to, among other things: (a) select participants, (b) determine the types of awards that participants are to receive and the number of shares that are to be subject to such awards and (c) establish the terms and conditions of awards, including the price (if any) to be paid for the shares subject to the award. The types of awards that may be granted under the 2016 Incentive Plan include stock options, RSUs, restricted stock, performance awards and other forms of awards granted or denominated in shares of Vistra Energy common stock, as well as certain cash-based awards. 28 If any stock option or other stock-based award granted under the 2016 Incentive Plan expires, terminates or is canceled for any reason without having been exercised in full, the number of shares of Vistra Energy common stock underlying any unexercised award shall again be available for the purpose of awards under the 2016 Incentive Plan. If any shares of restricted stock, performance awards or other stock-based awards denominated in shares of Vistra Energy common stock awarded under the 2016 Incentive Plan are forfeited for any reason, the number of forfeited shares shall again be available for purposes of awards under the 2016 Incentive Plan. Any award under the 2016 Incentive Plan settled in cash shall not be counted against the maximum share limitation. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2016 Incentive Plan and any outstanding awards, as well as the exercise or purchase price of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the Vistra Energy stockholders. B. Legal/Disciplinary History None of the foregoing officers or directors have, in the last five years, been the subject of any of the following: (1) a conviction in a criminal proceeding or named as a defendant in a pending criminal proceeding (excluding traffic violations and other minor offenses); (2) the entry of an order, judgment or decree, not subsequently reversed, suspended or vacated, by a court of competent jurisdiction that permanently or temporarily enjoined, barred, suspended or otherwise limited such person's involvement in any type of business, securities, commodities or banking activities; (3) a finding or judgment by a court of competent jurisdiction (in a civil action), the SEC, the CFTC or a state securities regulator of a violation of federal or state securities or commodities law, which finding or judgment has not been reversed, suspended or vacated; or (4) the entry of an order by a self-regulatory organization that permanently or temporarily barred, suspended or otherwise limited such person’s involvement in any type of business or securities activities. C. Disclosure of Family Relationships There are no family relationships (defined as any relationship by blood, marriage or adoption, not more remote than first cousin) among and between the Company's directors, officers, persons nominated or chosen by the Company to become directors or officers, or beneficial owners of more than five percent (5%) of any class of the Company's equity securities. D. Disclosure of Related Party Transactions In connection with the Emergence, we entered into agreements with certain of our affiliates and with parties who received shares of common stock and TRA Rights in exchange for their claims. Registration Rights Agreement Pursuant to the Plan of Reorganization, on the Effective Date, we entered into a Registration Rights Agreement (the Registration Rights Agreement) with certain selling stockholders providing for registration of the resale of the Vistra Energy common stock held by such selling stockholders. In December 2016, we filed a Form S-1 registration statement with the SEC to register for resale the shares of Vistra Energy common stock held by certain significant stockholders pursuant to the Registration Rights Agreement. The registration statement was amended in February 2017. The registration statement has not yet been declared effective by the SEC. Among other things, under the terms of the Registration Rights Agreement: • we will be required to use reasonable best efforts to convert the registration statement into a registration statement on Form S-3 as soon as reasonably practicable after we become eligible to do so and to have such Form S-3 declared effective as promptly as practicable (but in no event more than 30 days after it is filed with the SEC); • if we propose to file certain types of registration statements under the Securities Act with respect to an offering of equity securities, we will be required to use our reasonable best efforts to offer the other parties to the Registration Rights Agreement the opportunity to register all or part of their shares on the terms and conditions set forth in the Registration Rights Agreement; and 29 • the selling stockholders received the right, subject to certain conditions and exceptions, to request that we file registration statements or amend or supplement registration statements, with the SEC for an underwritten offering of all or part of their respective shares of Vistra Energy common stock (a Demand Registration), and the Company is required to cause any such registration statement or amendment or supplement (a) to be filed with the SEC promptly and, in any event, on or before the date that is 45 days, in the case of a registration statement on Form S-1, or 30 days, in the case of a registration statement on Form S-3, after we receive the written request from the relevant selling stockholders to effectuate the Demand Registration and (b) to become effective as promptly as reasonably practicable and in any event no later than 120 days after it is initially filed. All expenses of registration under the Registration Rights Agreement, including the legal fees of one counsel retained by or on behalf of the selling stockholders, will be paid by us. The foregoing description of the Registration Rights Agreement is qualified in its entirety by reference to the full text of the Registration Rights Agreement, which was filed as Exhibit 18(G) to the Initial Disclosure Statement filed on October 4, 2016. Stockholder's Agreements Pursuant to the Plan of Reorganization, on the Effective Date, we entered into three separate stockholder's agreements with affiliates of each of Apollo Management Holdings L.P., Brookfield Asset Management Private Institutional Capital Adviser (Canada), L.P. and Oaktree Capital Management, L.P (Stockholder's Agreement). Pursuant to each Stockholder's Agreement, subject to the proper exercise of fiduciary duties of the Board, the applicable stockholder will, until the occurrence of a Termination Event (as defined below), be entitled to designate one person for nomination for election to the Board as a Class III director at (a) any meeting of our stockholders at which Class III directors are elected or (b) if our Charter no longer provides for the division of directors into three classes, any meeting of our stockholders at which directors are to be elected. Prior to the occurrence of a Termination Event, if a vacancy occurs because of the death, disability, disqualification, resignation or removal of the director nominee of an applicable stockholder, subject to the proper exercise of the fiduciary duties of the Board, the applicable stockholder will be entitled to designate such person's successor. For purposes of this section, a Termination Event means that such stockholder, together with its affiliates and investment funds, funds or accounts that are advised, managed or controlled by such stockholder or its affiliates (other than the Company or any entity that is controlled by the Company), ceases to beneficially own, in the aggregate, for a period of 20 consecutive trading days, at least 22,500,000 shares of common stock of Vistra Energy that were owned by such stockholder on the date of the applicable Stockholder's Agreement. The rights of each stockholder under its applicable Stockholder's Agreement will terminate automatically upon a Termination Event. The foregoing description of the Stockholders' Agreements is qualified in its entirety by reference to the full text of the form of Stockholder's Agreement, which was filed as Exhibit 18(H) to the Initial Disclosure Statement filed on October 4, 2016. Tax Receivable Agreement On the Effective Date, we entered into a tax receivable agreement (the TRA) with a transfer agent on behalf of certain former first lien creditors of TCEH. The TRA generally provides for the payment by us to holders of TRA Rights of 85% of the amount of cash savings, if any, in United States federal, state and local income tax that we realize in periods after Emergence as a result of (a) certain transactions consummated pursuant to the Plan of Reorganization (including any step-up in tax basis in our assets resulting from the PrefCo Preferred Stock Sale), (b) the tax basis of all assets acquired in connection with the Lamar and Forney Acquisition in April 2016 and (c) tax benefits related to imputed interest deemed to be paid by us as a result of payments under the TRA, plus interest accruing from the due date of the applicable tax return. Pursuant to the TRA, we issued the TRA Rights to our Predecessor to be held in escrow for the benefit of the first lien secured creditors of our Predecessor entitled to receive such TRA Rights under the Plan of Reorganization. Such TRA Rights are subject to various transfer restrictions described in the TRA and are entitled to certain registration rights more fully described in the Registration Rights Agreement. Further details concerning the terms of the TRA may be obtained by reviewing the TRA, which was filed as Exhibit 18(c) to the Initial Disclosure Statement filed on October 4, 2016. 30 The amount and timing of any payments under the TRA will vary depending upon a number of factors, including the amount and timing of the taxable income we generate in the future and the tax rate then applicable, our use of loss carryovers and the portion of our payments under the TRA constituting imputed interest. The payments we will be required to make under the TRA could be substantial. Future transactions or events could change the timing and/or amount of the actual tax benefits realized and the corresponding TRA payments from these tax attributes. In addition, although we are not aware of any issue that would cause the IRS to challenge the tax benefits that are the subject of the TRA, recipients of the payments under the TRA will not be required to reimburse us for any payments previously made if such tax benefits are subsequently disallowed. As a result, in such circumstances, Vistra Energy could make payments under the TRA that are greater than its actual cash tax savings and may not be able to recoup those payments, which could adversely affect our liquidity. In addition, because Vistra Energy is a holding company with no operations of its own, its ability to make payments under the TRA is dependent on the ability of its subsidiaries to make distributions to it. Vistra Energy's future debt agreements may restrict the ability of its subsidiaries to make distributions to it, which could affect its ability to make payments under the TRA. To the extent that Vistra Energy is unable to make payments under the TRA because of restriction under its debt agreements, such payments will be deferred and will accrue interest until paid, which could adversely affect our results of operations and could also affect our liquidity in periods in which such payments are made. Finally, the TRA provides that, in the event that Vistra Energy breaches any of its material obligations under the TRA, or upon certain mergers, asset sales, or other forms of business combination or certain other changes of control, the transfer agent under the TRA may treat such event as an early termination of the TRA, in which case Vistra Energy would be required to make an immediate payment to the holder of the TRA Rights equal to the present value (at a discount rate equal to LIBOR plus 100 basis points) of the anticipated future tax benefits based on certain assumptions. As a result, upon such a breach or change of control, Vistra Energy could be required to make a lump-sum payment under the TRA that is greater than the specified percentage of its actual cash tax savings and could have a substantial negative impact on our liquidity. The foregoing description of the TRA is qualified in its entirety by reference to the full text of the TRA, which was filed as Exhibit 18(c) to the Initial Disclosure Statement filed on October 4, 2016. Tax Matters Agreement On the Effective Date, we entered into a Tax Matters Agreement (the Tax Matters Agreement), with EFH Corp. whereby the parties have agreed to take certain actions and refrain from taking certain actions in order to preserve the intended tax treatment of the Spin-Off and to indemnify the other parties to the extent a breach of such agreement results in additional taxes to the other parties. Among other things, the Tax Matters Agreement allocates the responsibility for taxes for periods prior to the Spin-Off between EFH Corp. and us. For periods prior to the Spin-Off: (a) Vistra Energy is generally required to reimburse EFH Corp. with respect to any taxes paid by EFH Corp. that are attributable to us and (b) EFH Corp. is generally required to reimburse us with respect to any taxes paid by us that are attributable to EFH Corp. We are also required to indemnify EFH Corp. against taxes, under certain circumstance, if the IRS or another taxing authority successfully challenges the amount of gain relating to the PrefCo Preferred Stock Sale or the amount or allowance of EFH Corp.'s net operating loss deductions. Subject to certain exceptions, the Tax Matters Agreement prohibits us from taking certain actions that could reasonably be expected to undermine the intended tax treatment of the Spin-Off or to jeopardize the conclusions of the private letter ruling we obtained from the IRS or opinions of counsel received by us or EFH Corp., in each case, in connection with the Spin-Off. Certain of these restrictions apply for two years after the Spin-Off. Under the Tax Matters Agreement, we may engage in an otherwise restricted action if (a) we obtain written consent from EFH Corp., (b) such action or transaction is described in or otherwise consistent with the facts in the private letter ruling we obtained from the IRS in connection with the Spin-Off, (c) we obtain a supplemental private letter ruling from the IRS, or (d) we obtain an unqualified opinion of a nationally recognized law or accounting firm that is reasonably acceptable to EFH Corp. that the action will not affect the intended tax treatment of the Spin-Off. 31 The foregoing description of the Tax Matters Agreement is qualified in its entirety by reference to the full text of the Tax Matters Agreement, which was filed as Exhibit 18(D) to the Initial Disclosure Statement filed on October 4, 2016. Separation Agreement Pursuant to the Plan of Reorganization, on the Effective Date, EFH Corp., Vistra Energy and Vistra Operations entered into a Separation Agreement (the Separation Agreement). Under the key terms of the Separation Agreement, on the Effective Date, EFH Corp. and certain other Debtors (including EFCH and TCEH) transferred to Vistra Energy certain assets and liabilities related to the TCEH Debtors' operations, including certain employee benefit plans specifically identified in the Separation Agreement, which Vistra Energy, in turn, transferred to Vistra Operations. Pursuant to the Separation Agreement, Vistra Operations accepted, assumed and agreed to faithfully perform, discharge and fulfill certain assumed liabilities. The Contribution was effected pursuant to the side-by-side operation of the Separation Agreement and the Plan of Reorganization. The foregoing description of the Separation Agreement is qualified in its entirety by reference to the full text of the Separation Agreement, which was filed as Exhibit 18(b) to the Initial Disclosure Statement filed on October 4, 2016.

E. Disclosure of Conflicts of Interests None 32 Item 12: Annual financial statements. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Stockholders of Vistra Energy Corp. Dallas, TX We have audited the accompanying consolidated balance sheet of Vistra Energy Corp. (the "Company") as of December 31, 2016 (Successor Company balance sheet) and 2015 (Predecessor Company balance sheet), and the related statements of consolidated income (loss), consolidated comprehensive income (loss), consolidated cash flows, and consolidated equity, for the period October 3, 2016 through December 31, 2016 (Successor Company operations), the period January 1, 2016 through October 2, 2016, and for each of the two years in the period ended December 31, 2015 (Predecessor Company operations). These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. As discussed in Note 2 to the financial statements, on August 29, 2016 the Bankruptcy Court entered an order confirming the plan of reorganization which became effective on October 3, 2016. Accordingly, the accompanying financial statements have been prepared in conformity with Accounting Standards Codification (ASC) Topic 852, Reorganizations, for the Successor Company as a new entity with assets, liabilities, and a capital structure having carrying values not comparable with prior periods as described in Note 1 to the financial statements. In our opinion, the Successor Company financial statements present fairly, in all material respects, the financial position of Vistra Energy Corp. as of December 31, 2016, and the results of their operations and their cash flows for the period October 3, 2016 through December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. Further, in our opinion, the Predecessor Company financial statements referred to above present fairly, in all material respects, the financial position of the Predecessor Company as of December 31, 2015, and the results of their operations and their cash flows for the period January 1, 2016 through October 2, 2016, and for each of the two years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. /s/ DELOITTE & TOUCHE LLP Dallas, TX March 30, 2017 33 VISTRA ENERGY CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Description of Business, Bankruptcy Proceedings and Emergence References in this report to "we," "our," "us" and "the Company" are to Vistra Energy and/or its subsidiaries in the Successor period, and to TCEH and/or its subsidiaries in the Predecessor periods, as apparent in the context. See Glossary for defined terms. On April 29, 2014 (the Petition Date), EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities (collectively, the Debtors), 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). On October 3, 2016 (the Effective Date), subsidiaries of TCEH that were Debtors in the Chapter 11 Cases (the TCEH Debtors) and certain EFH Corp. subsidiaries (the Contributed EFH Debtors) completed their reorganization under the Bankruptcy Code and emerged from the Chapter 11 Cases (Emergence) as subsidiaries of a newly-formed company, Vistra Energy (our Successor). On the Effective Date, Vistra Energy was spun-off from EFH Corp. in a tax-free transaction to the former first lien creditors of TCEH (Spin-Off). As a result, as of the Effective Date, Vistra Energy is a holding company for subsidiaries principally engaged in competitive electricity market activities including power generation, wholesale energy sales and purchases, commodity risk management and retail sales of electricity to end users. TCEH is the Predecessor to Vistra Energy. See Note 2 for further discussion regarding the Chapter 11 Cases. Vistra Energy is a holding company operating an integrated power business in Texas. Through our Luminant and TXU Energy subsidiaries, we are engaged in competitive electricity market activities including power generation, wholesale energy sales and purchases, commodity risk management and retail sales of electricity to end users. Prior to the Effective Date, TCEH was a holding company for subsidiaries principally engaged in the same activities as Vistra Energy. Subsequent to the Effective Date, Vistra Energy has two reportable segments: our Wholesale Generation segment, consisting largely of Luminant, and our Retail Electricity segment, consisting largely of TXU Energy. Prior to the Effective Date, there were no reportable business segments for our Predecessor. See Note 21 for further information concerning reportable business segments. Basis of Presentation As of the Effective Date, Vistra Energy applied fresh start reporting under the applicable provisions of Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 852, Reorganizations (ASC 852). Fresh start reporting includes (1) distinguishing the consolidated financial statements of the entity that was previously in restructuring (TCEH, or the Predecessor) from the financial statements of the entity that emerges from restructuring (Vistra Energy, or the Successor), (2) accounting for the effects of the Plan of Reorganization, (3) assigning the reorganized value of the Successor entity by measuring all assets and liabilities of the Successor entity at fair value, and (4) selecting accounting policies for the Successor entity. The financial statements of Vistra Energy for periods subsequent to the Effective Date are not comparable to the financial statements of TCEH for periods prior to the Effective Date, as those previous periods do not give effect to any adjustments to the carrying values of assets or amounts of liabilities that resulted from the Plan of Reorganization and the related application of fresh start reporting. The reorganization value of Vistra Energy was assigned to its assets and liabilities in conformity with the procedures specified by FASB ASC 805, Business Combinations, and the portion of the reorganization value that was not attributable to identifiable tangible or intangible assets was recognized as goodwill. See Note 3 for further discussion regarding fresh start reporting. The consolidated financial statements of the Predecessor reflect the application of ASC 852 as it applies to entities that have filed a petition for bankruptcy under Chapter 11 of the Bankruptcy Code. As a result, the consolidated financial statements of the Predecessor have been prepared as if TCEH was a going concern and contemplated the realization of assets and liabilities in the normal course of business. During the Chapter 11 Cases, the Debtors operated their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. The guidance requires that transactions and events directly associated with the reorganization be distinguished from the ongoing operations of the business. In addition, the guidance provides for changes in the accounting and presentation of liabilities. Prior to the Effective Date, the Predecessor recorded the effects of the Plan of Reorganization in accordance with ASC 852. See Notes 4 and 5 for further discussion of these accounting and reporting changes. 42 The consolidated financial statements have been prepared in accordance with US GAAP. All intercompany transactions and balances have been eliminated in consolidation. All dollar amounts in the financial statements and tables in the notes are stated in millions of US dollars unless otherwise indicated. Subsequent events have been evaluated through March 30, 2017, the date these consolidated financial statements were issued. Use of Estimates Preparation of financial statements requires estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of revenue and expense, including fair value measurements, estimates of expected obligations, judgment related to the potential timing of events and other estimates. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. Derivative Instruments and Mark-to-Market Accounting We enter into contracts for the purchase and sale of electricity, natural gas, coal, uranium and other commodities and also enter into other derivative instruments such as options, swaps, futures and forwards primarily to manage commodity price and interest rate risks. If the instrument meets the definition of a derivative under accounting standards related to derivative instruments and hedging activities, changes in the fair value of the derivative are recognized in net income as unrealized gains and losses, unless the criteria for certain exceptions are met, and an offsetting derivative asset or liability is recorded in the consolidated balance sheets. This recognition is referred to as mark-to-market accounting. The fair values of our unsettled derivative instruments under mark-to-market accounting are reported in the consolidated balance sheets as commodity and other derivative contractual assets or liabilities. We report derivative assets and liabilities in the consolidated balance sheets without taking into consideration netting arrangements we have with counterparties. Margin deposits that contractually offset these assets and liabilities are reported separately in the consolidated balance sheets. When derivative instruments are settled and realized gains and losses are recorded, the previously recorded unrealized gains and losses and derivative assets and liabilities are reversed. See Notes 16 and 17 for additional information regarding fair value measurement and commodity and other derivative contractual assets and liabilities. Under the election criteria of accounting standards related to derivative instruments and hedging activities, we may elect the normal purchase and sale exemption. A commodity-related derivative contract may be designated as a normal purchase or sale if the commodity is to be physically received or delivered for use or sale in the normal course of business. If designated as normal, the derivative contract is accounted for under the accrual method of accounting (not marked-to-market) with no balance sheet or income statement recognition of the contract until settlement. Because derivative instruments are frequently used as economic hedges, accounting standards related to derivative instruments and hedging activities allow for hedge accounting, which provides for the designation of such instruments as cash flow or fair value hedges if certain conditions are met. At December 31, 2016 and 2015, there were no derivative positions accounted for as cash flow or fair value hedges. Realized and unrealized gains and losses from transacting in energy-related derivative instruments are primarily reported in the statements of consolidated income (loss) in either operating revenues or fuel, purchased power costs and delivery fees in the Successor period depending on the type of derivative instrument and net gain (loss) from commodity hedging and trading activities in the Predecessor period. Further, realized and unrealized gains and losses associated with interest rate swap transactions are reported in the statements of consolidated income (loss) in interest expense for both the Predecessor and Successor. Revenue Recognition We record revenue from electricity sales under the accrual method of accounting. Revenues are recognized when electricity is provided to customers on the basis of periodic cycle meter readings and include an estimated accrual for the revenues earned from the meter reading date to the end of the period (unbilled revenue). 43 In the statements of consolidated income (loss), we report physically delivered commodity sales and related hedging activity in operating revenues and physically delivered purchases and related hedging activity in fuel, purchased power costs and delivery fees for the Successor period, whereas hedging activity was reported as net gain (loss) from commodity hedging and trading activities in the Predecessor period. Volumes under bilateral purchase and sales contracts, including contracts intended as hedges, are not scheduled as physical power with ERCOT. Accordingly, unless the volumes represent physical deliveries to customers or purchases from counterparties, such contracts are reported in operating revenues, for the Successor, and in net gain (loss) from commodity hedging and trading activities, for the Predecessor. If volumes delivered to our retail and wholesale customers are less than our generation volumes (as determined on a daily settlement basis), we record net bilateral activity as wholesale revenues, and if volumes delivered to our retail and wholesale customers exceed our generation volumes, we record net bilateral activity as purchased costs in the Successor period. The additional wholesale revenues or purchased power costs were offset in net gain (loss) from commodity hedging and trading activities in the Predecessor period. Advertising Expense We expense advertising costs as incurred and include them within selling, general and administrative expenses. Advertising expenses totaled $9 million, $35 million, $44 million and $42 million for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. Impairment of Long-Lived Assets We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever indications of impairment exist. The carrying value of such assets is deemed to be impaired if the projected undiscounted cash flows are less than the carrying value. If there is such impairment, a loss would be recognized based on the amount by which the carrying value exceeds the fair value. Fair value is determined primarily by discounted cash flows, supported by available market valuations, if applicable. See Note 8 for discussion of impairments of certain long-lived assets recorded by the Predecessor. Finite-lived intangibles identified as a result of fresh start reporting are amortized over their estimated useful lives based on the expected realization of economic effects. See Note 7 for details of intangible assets with indefinite lives, including discussion of fair value determinations. Goodwill and Intangible Assets with Indefinite Lives As part of fresh start reporting, reorganization value is generally allocated, first, to identifiable tangible assets, identifiable intangible assets and liabilities, then any remaining excess reorganization value is allocated to goodwill (see Note 3). We evaluate goodwill and intangible assets with indefinite lives for impairment at least annually, or when indications of impairment exist. As part of fresh start reporting, we have established October 1 as the date we evaluate goodwill and intangible assets with indefinite lives for impairment. The Predecessor's annual evaluation date was December 1. See Note 7 for details of goodwill, including discussion of fair value determinations and our Predecessor's goodwill impairments. Nuclear Fuel Nuclear fuel is capitalized and reported as a component of our property, plant and equipment in our consolidated balance sheets. Amortization of nuclear fuel is calculated on the units-of-production method and is reported as a component of fuel, purchased power costs and delivery fees in our statements of consolidated income (loss). Major Maintenance Costs Major maintenance costs incurred by the Successor during generation plant outages are deferred and amortized into operating costs over the period between the major maintenance outages for the respective asset. Other costs of maintenance activities are charged to expense as incurred and reported as operating costs in our statements of consolidated income (loss). The Predecessor charged major and other maintenance activities to expense as incurred. 44 Defined Benefit Pension Plans and OPEB Plans On the Effective Date, EFH Corp. transferred sponsorship of certain employee benefit plans (including related assets), programs and policies to a subsidiary of Vistra Energy. Certain health care and life insurance benefits are offered to eligible employees and their dependents upon the retirement of such employee from the company and also offer pension benefits to eligible employees under collective bargaining agreements based on either a traditional defined benefit formula or a cash balance formula. Effective January 1, 2017, the OPEB plan was amended to discontinue the life insurance benefits for active employees. Costs of pension and OPEB plans are dependent upon numerous factors, assumptions and estimates. Prior to the Effective Date, our Predecessor bore a portion of the costs of the EFH Corp. sponsored pension and OPEB plans and accounted for the arrangement under multiemployer plan accounting. See Note 18 for additional information regarding pension and OPEB plans. Stock-Based Compensation Stock-based compensation is accounted for in accordance with ASC 718, Compensation - Stock Compensation. The fair value of our non-qualified stock options is estimated on the date of grant using the Black-Scholes option-pricing model. Forfeitures are recognized as they occur. We recognize compensation expense for graded vesting awards on a straight-line basis over the requisite service period for the entire award. See Note 19 for additional information regarding stock-based compensation. Sales and Excise Taxes Sales and excise taxes are accounted for as a "pass through" item on the consolidated balance sheets with no effect on the statements of consolidated income (loss) (i.e., the tax is billed to customers and recorded as trade accounts receivable with an offsetting amount recorded as a liability to the taxing jurisdiction). Franchise and Revenue-Based Taxes Unlike sales and excise taxes, franchise and gross receipt taxes are not a "pass through" item. These taxes are imposed on us by state and local taxing authorities, based on revenues or kWh delivered, as a cost of doing business and are recorded as an expense. Rates we charge to customers are intended to recover our costs, including the franchise and gross receipt taxes, but we are not acting as an agent to collect the taxes from customers. We report franchise and revenue-based taxes in SG&A expense in our statements of consolidated income (loss). Income Taxes Subsequent to the Effective Date, Vistra Energy will file a consolidated US federal income tax return. Prior to the Effective Date, EFH Corp. filed a consolidated US federal income tax return that included the results of our Predecessor; however, our Predecessor's income tax expense and related balance sheet amounts were recorded as if it filed separate corporate income tax returns. Deferred income taxes are provided for temporary differences between the book and tax basis of assets and liabilities as required under accounting rules. See Note 9. We report interest and penalties related to uncertain tax positions as current income tax expense. See Note 9. Accounting for Contingencies Our financial results may be affected by judgments and estimates related to loss contingencies. Accruals for loss contingencies are recorded when management determines that it is probable that an asset has been impaired or a liability has been incurred and that such economic loss can be reasonably estimated. Such determinations are subject to interpretations of current facts and circumstances, forecasts of future events and estimates of the financial impacts of such events. See Note 14 for a discussion of contingencies. 45 Cash and Cash Equivalents For purposes of reporting cash and cash equivalents, temporary cash investments purchased with a remaining maturity of three months or less are considered to be cash equivalents. Restricted Cash The terms of certain agreements require the restriction of cash for specific purposes. See Notes 13 and 22 for more details regarding restricted cash. Property, Plant and Equipment In connection with fresh start reporting, carrying amounts of property, plant and equipment were adjusted to estimated fair values as of the Effective Date (see Note 3). Significant improvements or additions to our property, plant and equipment that extend the life of the respective asset are capitalized at cost, while other costs are expensed when incurred. The cost of self- constructed property additions includes materials and both direct and indirect labor and applicable overhead, including payroll- related costs. Interest related to qualifying construction projects and qualifying software projects is capitalized in accordance with accounting guidance related to capitalization of interest cost. See Note 11. Depreciation of our property, plant and equipment (except for nuclear fuel) is calculated on a straight-line basis over the estimated service lives of the properties. Depreciation expense is calculated on an asset-by-asset basis. Estimated depreciable lives are based on management's estimates of the assets' economic useful lives. See Note 22. Asset Retirement Obligations (ARO) A liability is initially recorded at fair value for an asset retirement obligation associated with the legal obligation associated with law, regulatory, contractual or constructive retirement requirements of tangible long-lived assets in the period in which it is incurred if a fair value is reasonably estimable. At initial recognition of an ARO obligation, an offsetting asset is also recorded for the long-lived asset that the liability corresponds with, which is subsequently depreciated over the estimated useful life of the asset. These liabilities primarily relate to our nuclear generation plant decommissioning, land reclamation related to lignite mining, removal of lignite/coal fueled plant ash treatment facilities and generation plant asbestos removal and disposal costs. Over time, the liability is accreted for the change in present value and the initial capitalized costs are depreciated over the remaining useful lives of the assets. Generally, changes in estimates related to ARO obligations are recorded as increases to the liability and related asset as information becomes available. See Note 22. Inventories Inventories consist of materials and supplies, fuel stock and natural gas in storage. Materials and supplies inventory is valued at weighted average cost and is expensed or capitalized when used for repairs/maintenance or capital projects, respectively. Fuel stock and natural gas in storage are reported at the lower of cost (on a weighted average basis) or market. We expect to recover the value of inventory costs in the normal course of business. Investments Investments in a nuclear decommissioning trust fund are carried at current market value in the consolidated balance sheets. Assets related to employee benefit plans represent investments held to satisfy deferred compensation liabilities and are recorded at current market value. See Note 22 for discussion of these and other investments. Changes in Accounting Standards In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2016-02 (ASU 2016-02), Leases. The ASU amends previous GAAP to require the recognition of lease assets and liabilities for operating leases. The ASU will be effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Retrospective application to comparative periods presented will be required in the year of adoption. We are currently evaluating the impact of this ASU on our financial statements. 46 In May 2016, the FASB issued Accounting Standards Update 2016-09, Revenue from Contracts with Customers (Topic 606), which was further amended through various updates issued by the FASB thereafter. The guidance under Topic 606 provides the core principle and key steps in determining the recognition of revenue and expands disclosure requirements related to revenue recognition. We intend to adopt the new standard on January 1, 2018 using the modified retrospective method and expect to elect the practical expedient available under Topic 606 for measuring progress toward complete satisfaction of a performance obligation and for disclosure requirements of remaining performance obligations. The practical expedient allows an entity to recognize revenue in the amount to which the entity has the right to invoice such that the entity has a right to the consideration in an amount that corresponds directly with the value to the customer for performance completed to date by the entity. In 2016, we continued to assess the new standard, including the expanded disclosure requirements. We do not anticipate that the adoption of the standard will have a material effect on our results of operations, cash flows or financial condition. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). The ASU provides for a new impairment model which requires measurement and recognition of expected credit losses for most financial assets held. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. We do not anticipate ASU 2016-13 to have a material impact on our financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). The ASU provides for the elimination of Step 2 from the goodwill impairment test. If impairment charges are recognized, the amount recorded will be the amount by which the carrying amount exceeds the reporting unit's fair value with certain limitations. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017 and the adoption should be applied prospectively. We expect to early adopt this standard in 2017. We do not currently anticipate ASU 2017-04 to have a material impact on our financial statements. 47 2. EMERGENCE FROM CHAPTER 11 CASES On the Petition Date, EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities, filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware. On the Effective Date, the TCEH Debtors and the Contributed EFH Debtors completed their reorganization under the Bankruptcy Code and emerged from the Chapter 11 Cases as subsidiaries of Vistra Energy. Separation of Vistra Energy from EFH Corp. and its Subsidiaries Upon the Effective Date, Vistra Energy separated from EFH Corp. pursuant to a tax-free spin-off transaction that was part of a series of transactions that included a taxable component. The taxable portion of the transaction generated a taxable gain that resulted in no regular tax liability due to available net operating loss carryforwards of EFH Corp. The transaction did result in an alternative minimum tax liability of approximately $14 million payable by EFH Corp. to the IRS. Vistra Energy has an obligation to reimburse EFH Corp. 50% of such alternative minimum tax, approximately $7 million, pursuant to the Tax Matters Agreement. The spin-off transaction resulted in Vistra Energy, including the TCEH Debtors and the Contributed EFH Debtors, no longer being an affiliate of EFH Corp. and its subsidiaries. In addition to the Plan of Reorganization, the separation was effectuated, in part, pursuant to the terms of a separation agreement, a transition services agreement and a tax matters agreement. Separation Agreement On the Effective Date, EFH Corp., Vistra Energy and a subsidiary of Vistra Energy entered into a separation agreement that provides for, among other things, the transfer of certain assets and liabilities by EFH Corp., EFCH and TCEH to Vistra Energy. Among other things, EFH Corp., EFCH and/or TCEH, as applicable, (a) transferred the TCEH Debtors and certain contracts and assets (and related liabilities) primarily related to the business of the TCEH Debtors to Vistra Energy, (b) transferred sponsorship of certain employee benefit plans (including related assets), programs and policies to a subsidiary of Vistra Energy and (c) assigned certain employment agreements from EFH Corp. and certain of the Contributed EFH Debtors to a subsidiary of Vistra Energy. Tax Matters Agreement On the Effective Date, Vistra Energy and EFH Corp. entered into a tax matters agreement (the Tax Matters Agreement), which provides for the allocation of certain taxes among the parties and for certain rights and obligations related to, among other things, the filing of tax returns, resolutions of tax audits and preserving the tax-free nature of the spin-off. See Note 9 for further information about the Tax Matters Agreement. Settlement Agreement The Debtors, the Sponsor Group, certain settling TCEH first lien creditors, certain settling TCEH second lien creditors, certain settling TCEH unsecured creditors and the official committee of unsecured creditors of the TCEH Debtors entered into a settlement agreement (the Settlement Agreement) in August 2015 (as amended in September 2015 and approved by the Bankruptcy Court in December 2015) to settle, among other things, (a) intercompany claims among the Debtors, (b) claims and causes of actions against holders of first lien claims against TCEH and the agents under the TCEH Senior Secured Facilities, (c) claims and causes of action against holders of interests in EFH Corp. and certain related entities and (d) claims and causes of action against each of the Debtors' current and former directors, the Sponsor Group, managers and officers and other related entities. Tax Matters In July 2016, EFH Corp. received a private letter ruling from the IRS in connection with our emergence from bankruptcy, which provides, among other things, for certain rulings regarding the qualification of (a) the transfer of certain assets and ordinary course operating liabilities to Vistra Energy and (b) the distribution of the equity of Vistra Energy, the cash proceeds from Vistra Energy debt, the cash proceeds from the sale of preferred stock in a newly-formed subsidiary of Vistra Energy, and the right to receive payments under a tax receivables agreement, to holders of TCEH first lien claims, as a reorganization qualifying for tax- free treatment. 48 Pre-Petition Claims On the Effective Date, the TCEH Debtors (together with the Contributed EFH Debtors) emerged from the Chapter 11 Cases and discharged approximately $33.8 billion in LSTC. Distributions for the settled claims related to the funded debt of the TCEH Debtors commenced subsequent to the Effective Date. With respect to remaining claims related to the TCEH Debtors, as of December 31, 2016, the TCEH Debtors have approximately $54 million in escrow to allocate among and resolve the remaining claims, which consist primarily of remaining trade payable and legal claims, including asbestos claims. The Bankruptcy code allows up to 180 days from the Effective Date to resolve these claims. These remaining claims and the related escrow balance for the claims are recorded in Vistra Energy's consolidated balance sheet as other current liabilities and restricted cash, respectively. 3. FRESH START REPORTING As of the Effective Date, Vistra Energy applied fresh start reporting under the applicable provisions of ASC 852. In order to apply fresh-start reporting, ASC 852 requires two criteria to be satisfied: (1) that total post petition liabilities and allowed claims immediately before the date of confirmation of the Plan of Reorganization be in excess of reorganization value and (2) that holders of our Predecessor's voting shares immediately before confirmation of the Plan receive less than 50% of the voting shares of the emerging entity. Vistra Energy met both criteria. Under ASC 852, application of fresh start reporting is required on the date on which a plan of reorganization is confirmed by a bankruptcy court and all material conditions to the plan of reorganization are satisfied. All material conditions to the Plan of Reorganization were satisfied on the Effective Date, including the execution of the Spin-Off. Reorganization Value A third-party valuation specialist submitted a report to the Bankruptcy Court in July 2016 assuming an emergence from bankruptcy as of December 31, 2016. This report provided an estimated value range for the total Vistra Energy enterprise. Management selected an enterprise value within that range of $10.5 billion. The enterprise value submitted by the valuation specialist was based upon: • • • • • • • historical financial information of our Predecessor for recent years and interim periods; certain internal financial and operating data of our Predecessor; certain financial, tax and operational forecasts of Vistra Energy; certain publicly available financial data for comparable companies to the operating business of Vistra Energy; the Plan of Reorganization and related documents; certain economic and industry information relevant to the operating business, and other studies, analyses and inquiries. The valuation analysis for Vistra Energy included (i) a discounted cash flow calculation and (ii) peer group company analysis. Equal weighting was assigned to the two methodologies, before adding the value of the tax basis step-up resulting from certain transactions pursuant to the Plan of Reorganization, which was valued separately. The estimated future cash flows included annual forecasts through 2021. A terminal value was included in the discounted cash flow calculation using an exit multiple approach based on the cash flows of the final year of the forecast period. The valuation analysis used a discount rate of approximately 7%. The determination of the discount rate takes into consideration the capital structure, credit ratings and current debt yields of comparable publicly traded companies as well as an estimate of return on equity that reflects historical market returns and current market volatility for the industry. Although the Company believes the assumptions and estimates used by the valuation specialist to develop the enterprise value are reasonable and appropriate, different assumption and estimates could materially impact the analysis and resulting conclusions. 49 Under ASC 852, reorganization value is generally allocated, first, to identifiable tangible assets, identifiable intangible assets and liabilities, then any remaining excess reorganization value is allocated to goodwill. Vistra Energy estimates its reorganization value of assets at approximately $15.161 billion as of October 3, 2016, which consists of the following: Business enterprise value Cash excluded from business enterprise value Deferred asset related to prepaid capital lease obligation Current liabilities, excluding short-term portion of debt and capital leases Noncurrent, non-interest bearing liabilities Vistra Energy reorganization value of assets Consolidated Balance Sheet $ $ 10,500 1,594 38 1,123 1,906 15,161 The adjustments to TCEH's October 3, 2016 consolidated balance sheet below include the impacts of the Plan of Reorganization and the adoption of fresh start reporting.

Also includes EFH Corp.'s contribution of liabilities associated with certain employee benefit plans to Vistra Energy. 51 (3) Net adjustments to cash, which represent distributions made or funding provided to an escrow account, classified as restricted cash, under the Plan of Reorganization, as follows: Sources (uses): Net proceeds from PrefCo preferred stock sale Addition of cash balances from the Contributed EFH Debtors Payments to TCEH first lien creditors, including adequate protection Payment to TCEH unsecured creditors (including $73 million to escrow) Payment of administrative claims to TCEH creditors Payment of legal fees, professional fees and other costs (including $52 million to escrow) Net use of cash $ $ 69 22 (486) (502) (53) (78) (1,028) (4) Increase in restricted cash primarily reflects amounts placed in escrow to satisfy certain secured claims, unsecured claims and professional fee obligations associated with the bankruptcy. (5) Reflects the deferred income tax impact of the Plan of Reorganization implementation, including cancellation of debts and adjustment of tax-basis for certain assets of PrefCo that issued mandatorily redeemable preferred stock as part of the Spin- Off. (6) Primarily reflects the reclassification of transmission and distribution service payables to Oncor from payables with affiliates to trade payables with third parties pursuant to the separation of Vistra Energy from EFH Corp. and payment of accrued professional fees and unsecured claimant obligations incurred in conjunction with Emergence. (7) Primarily reflects the payment of accrued interest and adequate protection to the TCEH first lien creditors on the Effective Date. (8) Primarily reflects the following: • Reclassification of $82 million from LSTC related to secured and unsecured claims and $16 million in accrued professional fees from accounts payable to other current liabilities. • Additional accruals for $23 million of change-in-control obligations and $26 million in success fees triggered by Emergence, $7 million in professional fees, and $28 million of accrued liabilities related to the Contributed EFH Entities. • Payment of $12 million in professional fees. (9) Reflects the conversion of the TCEH DIP Roll Facilities of $3.387 billion to the Vistra Operations Credit Facilities at Emergence, the issuance and sale of mandatorily redeemable preferred stock of PrefCo for $70 million, and the obligation related to a corporate office space lease contributed to Vistra Energy pursuant to the Plan of Reorganization. See Note 13 for additional details. 52 (10) Reflects the elimination of TCEH's liabilities subject to compromise pursuant to the Plan of Reorganization (see Note 5). Liabilities subject to compromise were settled as follows in accordance with the Plan of Reorganization: Notes, loans and other debt Accrued interest on notes, loans and other debt Net liability under terminated TCEH interest rate swap and natural gas hedging agreements Trade accounts payable and other expected allowed claims Third-party liabilities subject to compromise LSTC from the Contributed EFH Entities Total liabilities subject to compromise Fair value of equity issued to TCEH first lien creditors TRA Rights issued to TCEH first lien creditors Cash distributed and accruals for TCEH first lien creditors Cash distributed for TCEH unsecured claims Cash distributed and accruals for TCEH administrative claims Settlement of affiliate balances Net liabilities of contributed entities and other items Gain on extinguishment of LSTC $ $ 31,668 646 1,243 192 33,749 8 33,757 (7,741) (574) (377) (502) (60) (99) (60) 24,344 (11) Reflects the deferred income tax impact of the Plan of Reorganization implementation, including cancellation of debts and adjustment of tax basis of certain assets of PrefCo.

See Note 18 for further discussion of the benefit plan obligations. • Payment of $7 million in settlements related to split life insurance costs with a prior affiliate entity. (14) Reflects the issuance of approximately 427,500,000 shares of Vistra Energy common stock, par value of $0.01 per share, to the TCEH first lien creditors. See Note 15. 53 (15) Reflects adjustments to present Vistra Energy equity value at approximately $7.741 billion based on a reconciliation from the $10.5 billion enterprise value described above under Reorganization Value as depicted below: Enterprise value Vistra Operations Credit Facility – Initial Term Loan B Facility Vistra Operations Credit Facility – Term Loan C Facility Accrual for post-Emergence claims satisfaction Tax Receivable Agreement Obligation Preferred stock of PrefCo Other items Cash and cash equivalents Restricted cash Equity value at Emergence Common stock at par value Additional paid-in capital Equity value Shares outstanding at October 3, 2016 (in millions) Per share value (16) Membership Interest impact of Plan of Reorganization are shown below: Gain on extinguishment of LSTC Elimination of accumulated other comprehensive income Change in control payments Professional fees Other items Pretax gain on reorganization adjustments (Note 4) Deferred tax impact of the Plan of Reorganization and Spin-off Total impact to membership interests Fresh start adjustments $ $ $ $ $ $ $ 10,500 (2,871) (655) (181) (574) (70) (2) 801 793 7,741 4 7,737 7,741 427.5 18.11 24,344 (22) (23) (33) (14) 24,252 576 24,828 (17) Reflects the reduction of inventory to fair value, including (1) adjustment of fuel inventory to current market prices, and (2) an adjustment to the fair value of materials and supplies inventory primarily used in our lignite/coal fueled generation assets and related mining operations. (18) Reflects the $12 million increase in the fair value of certain real property assets and $3 million reduction of the fair value for other investments. 54 (19) Reflects the change in fair value of property, plant and equipment related primarily to generation and mining assets as detailed below: Property, Plant and Equipment Generation plants and mining assets Land Nuclear Fuel Other equipment Total Adjustment Fair Value $ $ (6,057) $ 140 (23) (30) (5,970) $ 3,698 490 157 97 4,442 We engaged a third-party valuation specialist to assist in preparing the values for our property, plant and equipment. For our generation plants and related mining assets, an income approach was utilized in valuing those assets based on discounted cash flow models that forecast the cash flows of the related assets over their respective useful lives. Significant estimates and assumptions utilized in those models include (1) long-term wholesale power price forecasts, (2) fuel cost forecasts, (3) expected generation volumes based on prevailing forecasts and expected maintenance outages, (4) operations and maintenance costs, (5) capital expenditure forecasts and (6) risk adjusted discount rates based on the cash flows produced by the specific generation asset. The fair value of the generation plants and mining assets is based upon Level 3 inputs utilized in the income approach. The fair value estimates for land and nuclear fuel utilized the market approach, which included utilizing recent comparable sales information and current market conditions for similarly situated land. Nuclear fuel values were determined by utilizing market pricing information for uranium. The fair value of land and nuclear fuel are based upon Level 3 inputs. (20) Reflects the adjustment in fair value of $2.256 billion to identifiable intangible assets, including $1.636 billion increase related to retail customer relationships, $270 million increase related to the retail trade name, $190 million increase related to an electricity supply contract, $164 million increase related to retail and wholesale contracts and $4 million decrease related to other intangible assets (see Note 7). Also reflects the reduction of fair value of $476 million to identifiable intangible liabilities, including a reduction of $525 million related to an electricity supply contract and an increase of $49 million to wholesale contracts. (21) Reflects the deferred income tax impact of fresh-start adjustments to property, plant, and equipment, inventory, intangibles and debt issuance costs. (22) Primarily reflects the following: • Addition of $197 million regulatory asset related to the deficiency of the nuclear decommissioning trust investment as compared to the nuclear generation plant retirement obligation. Pursuant to Texas regulatory provisions, the trust fund for decommissioning our nuclear generation facility is funded by a fee surcharge billed to REPs by Oncor, as a collection agent, and remitted monthly to Vistra Energy. • Adjustment to remove $26 million of unamortized debt issuance costs to reflect the Vistra Operations Credit Facilities at fair market value. (23) Reflects the increase in fair value of the Vistra Operations Credit Facilities in the amount of $151 million based on the quoted market prices of the facilities. (24) Increase in fair value of asset retirement obligation related to the plant retirement, mining and reclamation retirement, and coal combustion residuals. See Note 22 for further discussion of our asset retirement obligations. (25) Reflects the following: • Reduction in fair value of unfavorable contracts related to wholesale contracts and a portion of an electricity supply contract in the amount of $476 million. See footnote (20) above for further detail. 55 • Reduction of $465 million related to reduction in liability that represented excess amounts in the nuclear decommissioning trust above the carrying value of the asset retirement obligation related to our nuclear generation plant decommissioning. • Increase in fair value of obligations related to leased property in the amount of $29 million. • Increase in fair value of Pension and OPEB obligations in the amount of $12 million.

PREDECESSOR REORGANIZATION ITEMS Expenses and income directly associated with the Chapter 11 Cases are reported separately in the statements of consolidated loss as reorganization items as required by ASC 852, Reorganizations. Reorganization items also included adjustments to reflect the carrying value of LSTC at their estimated allowed claim amounts, as such adjustments were determined. For the period from January 1, 2016 through October 2, 2016, reorganization items include the gain from extinguishing LSTC and the impacts of fresh start reporting. The following table presents reorganization items as reported in the statements of consolidated loss: Gain on reorganization adjustments (Note 3) Loss from the adoption of fresh start reporting Expenses related to legal advisory and representation services Expenses related to other professional consulting and advisory services Contract claims adjustments Noncash adjustment for estimated allowed claims related to debt Adjustment to affiliate claims pursuant to Settlement Agreement (Note 20) Gain on settlement of debt held by affiliates (Note 20) Gain on settlement of interest on debt held by affiliates Sponsor management agreement settlement (Notes 2 and 20) Contract assumption adjustments Fees associated with extension/completion of the DIP Facility Noncash liability adjustment arising from termination of interest rate swaps Other Total reorganization items $ Predecessor Year Ended December 31, 2015 Post-Petition Period Ended December 31, 2014 Period from January 1, 2016 through October 2, 2016 $ (24,252) $ 2,013 55 39 13 — — — — — — — — 11 (22,121) $ — $ — 141 69 54 896 (635) (382) (20) (19) (14) 9 — 2 101 $ — — 65 67 19 — — — — — — 92 277 — 520 5. PREDECESSOR LIABILITIES SUBJECT TO COMPROMISE (LSTC) On the Effective Date, the TCEH Debtors (together with the Contributed EFH Debtors) emerged from the Chapter 11 Cases and discharged substantially all of the $33.8 billion in LSTC, which includes approximately $8 million of claims from the Contributed EFH Entities (see Note 3). The amounts classified as LSTC reflected the Predecessor's estimate of pre-petition liabilities and other expected allowed claims to be addressed in the Chapter 11 Cases. Amounts classified as LSTC did not include pre-petition liabilities that were fully collateralized by letters of credit, cash deposits or other credit enhancements. The following table presents LSTC as reported in the consolidated balance sheet at December 31, 2015: Notes, loans and other debt per the following table Accrued interest on notes, loans and other debt Net liability under terminated TCEH interest rate swap and natural gas hedging agreements (Note 17) Trade accounts payable, advances and other payables to affiliates and other expected allowed claims Total liabilities subject to compromise Predecessor December 31, 2015 31,668 $ 646 1,243 177 33,734 $ 57 Pre-Petition Notes, Loans and Other Debt Reported as LSTC Amounts presented below represent principal amounts of pre-petition notes, loans and other debt reported as LSTC at December 31, 2015.

LAMAR AND FORNEY ACQUISITION In April 2016, Luminant purchased all of the membership interests in La Frontera Holdings, LLC (La Frontera), the indirect owner of two combined-cycle gas turbine (CCGT) natural gas fueled generation facilities representing nearly 3,000 MW of capacity located in ERCOT, from a subsidiary of NextEra Energy, Inc. (the Lamar and Forney Acquisition). The facility in Forney, Texas has a capacity of 1,912 MW and the facility in Paris, Texas has a capacity of 1,076 MW. The acquisition diversified our fuel mix and increased the dispatch flexibility in our generation fleet. The aggregate purchase price was approximately $1.313 billion, which included the repayment of approximately $950 million of existing project financing indebtedness of La Frontera at closing, plus approximately $236 million for cash and net working capital. The purchase price was funded by cash-on-hand and additional borrowings under our Predecessor's DIP Facility totaling $1.1 billion. After completing the acquisition, we repaid approximately $230 million of borrowings under our Predecessor's DIP Revolving Credit Facility primarily utilizing cash acquired in the transaction. La Frontera and its subsidiaries were subsidiary guarantors under our Predecessor's DIP Roll Facilities and, on the Effective Date, became subsidiary guarantors under the Vistra Operations Credit Facilities (see Note 13). Predecessor Purchase Accounting The Lamar and Forney Acquisition was accounted for in accordance with ASC 805, Business Combinations (ASC 805), with identifiable assets acquired and liabilities assumed recorded at their estimated fair values on the acquisition date. To fair value the acquired property, plant and equipment, we used a discounted cash flow analysis, classified as Level 3 within the fair value hierarchy levels (see Note 16). This discounted cash flow model was created for each generation facility based on its remaining useful life. The discounted cash flow model included gross margin forecasts for each power generation facility determined using forward commodity market prices obtained from long-term forecasts. We also used management's forecasts of generation output, operations and maintenance expense, SG&A and capital expenditures. The resulting cash flows, estimated based upon the age of the assets, efficiency, location and useful life, were then discounted using plant specific discount rates of approximately 9%. The following table summarizes the consideration paid and the allocation of the purchase price to the fair value amounts recognized for the assets acquired and liabilities assumed related to the Lamar and Forney Acquisition as of the acquisition date. During the three months ended September 30, 2016, the working capital adjustment included in the purchase price was finalized between the parties, and the purchase price allocation was completed.

GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS Goodwill The following table provides information regarding the carrying value of goodwill. The goodwill of the Successor arose in connection with fresh start reporting that was applied at Emergence and was allocated to the Retail Electric segment (see Note 3). Of the goodwill recorded at Emergence, $1.686 billion is considered purchased goodwill and is deductible for tax purposes over 15 years on a straight-line basis. The goodwill of our Predecessor arose in connection with accounting for the Merger. Balance at beginning of period Noncash impairment charges Balance at end of period (a) Successor Period from October 3, 2016 through December 31, 2016 1,907 $ — 1,907 $ Predecessor Period from January 1, 2016 through October 2, 2016 152 $ — 152 $ $ $ Year Ended December 31, 2015 2,352 (2,200) 152 ____________ (a) At December 31, 2016, all goodwill related to the Retail Electricity segment. Predecessor periods are net of accumulated impairment charges totaling $18.170 billion. Predecessor Goodwill Impairments Goodwill and intangible assets with indefinite useful lives are required to be tested for impairment at least annually or whenever events or changes in circumstances indicate an impairment may exist. During the fourth quarter of 2015, our Predecessor performed a goodwill impairment analysis as of its annual testing date of December 1. Further, during the fourth quarter of 2015, there were significant declines in the market values of several similarly situated peer companies with publicly traded equity, which indicated our Predecessor's overall enterprise value should be reassessed. Our Predecessor's testing resulted in an impairment of goodwill of $800 million at December 1, 2015. During the first nine months of 2015, our Predecessor experienced impairment indicators related to decreases in forward wholesale electricity prices when compared to those prices reflected in its December 1, 2014 goodwill impairment testing analysis. As a result, the likelihood of goodwill impairments had increased, and our Predecessor initiated further testing of goodwill. Our Predecessor's testing of goodwill for impairment during the first nine months of 2015 resulted in impairment charges totaling $1.4 billion. 60 Identifiable Intangible Assets Identifiable intangible assets, including the impact of fresh start reporting (see Note 3), are comprised of the following: Identifiable Intangible Asset Retail customer relationship Software and other technology-related assets Electricity supply contract Retail and wholesale contracts Other identifiable intangible assets (a) Total identifiable intangible assets subject to amortization (b) Retail trade names (not subject to amortization) Mineral interests (not currently subject to amortization) Total identifiable intangible assets Successor December 31, 2016 Gross Carrying Amount $ 1,648 Accumulated Amortization 152 $ Net $ 1,496 $ 147 190 164 30 9 2 38 2 138 188 126 28 Gross Carrying Amount 463 385 — — 72 $ 2,179 $ 203 1,976 $ 920 $ 1,225 4 3,205 $ Predecessor December 31, 2015 Accumulated Amortization 442 $ $ Net 224 — — 35 701 5 1,179 $ ____________ (a) Includes favorable purchase and sales contracts, environmental allowances and credits and mining development costs. See discussion below regarding impairment charges recorded in the year ended December 31, 2015 related to other identifiable intangible assets. (b) Amounts related to fully amortized assets that are expired, or of no economic value, have been excluded from both the gross carrying and accumulated amortization amounts. Amortization expense related to finite-lived identifiable intangible assets (including the classification in the statements of consolidated income (loss)) consisted of: Successor Predecessor Remaining useful lives at December 31, 2016 (weighted average in years) 4 Period from October 3, 2016 through December 31, 2016 152 $ Period from January 1, 2016 through October 2, 2016 9 $ Year Ended December 31, 2015 2014 $ 17 $ 4 22 2 5 9 2 38 2 44 — — 6 60 — — 30 Statements of Consolidated Income (Loss) Line Depreciation and amortization Depreciation and amortization Operating revenues Operating revenues/ fuel, purchased power costs and delivery fees Operating revenues/ fuel, purchased power costs and delivery fees/depreciation and amortization Identifiable Intangible Asset Retail customer relationship Software and other technology-related assets Electricity supply contract Retail and wholesale contracts Other identifiable intangible assets Total amortization expense (a) $ 203 $ 59 $ 107 $ 170 _______________ (a) Amounts recorded in depreciation and amortization totaled $162 million, $58 million, $85 million and $116 million for the Successor period from October 3, 2016 through December 31, 2016, the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. 61 21 161 — — 37 219 955 23 59 — — 88 Following is a description of the separately identifiable intangible assets. In connection with fresh start reporting (see Note 3), the intangible assets were adjusted based on their estimated fair value as of the Effective Date, based on observable prices or estimates of fair value using valuation models. • Retail customer relationship – Retail customer relationship intangible asset represents the fair value of our non-contracted retail customer base, including residential and business customers, and is being amortized using an accelerated method based on historical customer attrition rates and reflecting the expected pattern in which economic benefits are realized over their estimated useful life. • Retail trade names – Our retail trade name intangible asset represents the fair value of the TXU EnergyTM and 4Change EnergyTM trade names, and was determined to be an indefinite-lived asset not subject to amortization. This intangible asset is evaluated for impairment at least annually in accordance with accounting guidance related to goodwill and other indefinite-lived intangible assets. Significant assumptions included within the development of the fair value estimate include TXU Energy's and 4Change Energy's estimated gross margins for future periods and implied royalty rates. • Electricity supply contract – The electricity supply contract represents a long-term fixed-price supply contract for the sale of electricity from one of our generation facilities that was measured at fair value at Emergence. The value of this contract under our Predecessor was recorded as an unfavorable liability due to prevailing market prices of electricity when the contract was established at the Merger. Significant assumptions included in the fair value measurement for this contract include long-term wholesale electricity price forecasts and operating cost forecasts for the respective generation facility. • Retail and wholesale contracts – These intangible assets represent the favorable value of various retail and wholesale contracts (both purchase and sale contracts) that were measured at fair value by utilizing prevailing market prices for commodities or services compared to the fixed prices contained in these agreements. The value of these contracts is being amortized using a method that is based on the monthly value of each contract measured at Emergence. Successor Estimated Amortization of Identifiable Intangible Assets As of December 31, 2016, the estimated aggregate amortization expense of identifiable intangible assets for each of the next five fiscal years is as shown below. Year 2017 2018 2019 2020 2021 Estimated Amortization Expense 523 $ 365 $ 267 $ 191 $ 143 $ Predecessor Intangible Impairments The impairments of generation facilities in 2015 (see Note 8) resulted in the impairment of the SO2 allowances under the Clean Air Act's acid rain cap-and-trade program that are associated with those facilities to the extent they are not projected to be used at other sites. The fair market values of the SO2 allowances were estimated to be de minimis based on Level 3 fair value estimates (see Note 16). Our Predecessor also impaired certain of its SO2 allowances under the Cross-State Air Pollution Rule (CSAPR) related to the impaired generation facilities. Accordingly, in the year ended December 31, 2015, our Predecessor recorded noncash impairment charges of $55 million (before deferred income tax benefit) in other deductions (see Note 22) related to its existing environmental allowances and credits intangible asset. SO2 emission allowances granted under the acid rain cap-and- trade program were recorded as intangible assets at fair value in connection with purchase accounting related to the Merger in 2007. Additionally, the impairments of generation and related mining facilities in September 2015 resulted in recording noncash impairment charges of $19 million (before deferred income tax benefit) in other deductions (see Note 22) related to mine development costs (included in other identifiable intangible assets in the table above) at the facilities. 62 During the three months ended March 31, 2015, our Predecessor determined that certain intangible assets related to favorable power purchase contracts should be evaluated for impairment. That conclusion was based on further declines in wholesale electricity prices in ERCOT experienced during the three months ended March 31, 2015. The fair value measurement was based on a discounted cash flow analysis of the contracts that compared the contractual price and terms of the contract to forecasted wholesale electricity and renewable energy credit (REC) prices in ERCOT. As a result of the analysis, our Predecessor recorded a noncash impairment charge of $8 million (before deferred income tax benefit) in other deductions (see Note 22). During the fourth quarter of 2014, our Predecessor determined that certain intangible assets related to favorable power purchase contracts should be evaluated for impairment. That conclusion was based on the combination of (1) the review of contracts for rejection as part of the Chapter 11 Cases, which could result in termination of contracts before the end of their estimated useful life and (2) declines in wholesale electricity prices. The fair value measurement was based on a discounted cash flow analysis of the contracts that compared the contractual price and terms of the contract to forecasted wholesale electricity and REC prices in ERCOT. As a result of the analysis, TCEH recorded a noncash impairment charge of $183 million (before deferred income tax benefit) in other deductions (see Note 22). As a result of the CSAPR, which became effective on January 1, 2015, and other new or proposed EPA rules, our Predecessor projected that as of December 31, 2014 it had excess SO2 emission allowances under the Clean Air Act's existing acid rain cap- and-trade program. In addition, the impairments of the Monticello, Martin Lake and Sandow 5 generation facilities (see Note 8) resulted in the impairment of the SO2 allowances associated with those facilities to the extent they are not projected to be used at other sites. The fair market values of the SO2 allowances were estimated to be de minimis based on Level 3 fair value estimates (see Note 16). Accordingly, a noncash impairment charge of $80 million (before deferred income tax benefit) was recorded in other deductions related to its existing environmental allowances and credits intangible asset in 2014. SO2 emission allowances previously granted were recorded as intangible assets at fair value in connection with purchase accounting related to the Merger in 2007. 8. PREDECESSOR IMPAIRMENT OF LONG-LIVED ASSETS Impairment of Lignite/Coal Fueled Generation and Mining Assets We evaluated our generation assets for impairment during 2015 as a result of impairment indicators related to the continued decline in forecasted wholesale electricity prices in ERCOT. Our evaluations concluded that impairments existed, and the carrying values at our Big Brown, Martin Lake, Monticello, Sandow 4 and Sandow 5 generation facilities and related mining facilities were reduced in total by $2.541 billion. Our fair value measurement for these assets was determined based on an income approach that utilized probability-weighted estimates of discounted future cash flows, which were Level 3 fair value measurements (see Note 16). Key inputs into the fair value measurement for these assets included current forecasted wholesale electricity prices in ERCOT, forecasted fuel prices, capital and operating expenditure forecasts and discount rates. 9. INCOME TAXES EFH Corp. files a US federal income tax return that includes the results of EFCH, EFIH, Oncor Holdings and, prior to the Effective Date, TCEH. Prior to the Effective Date, EFH Corp. was the corporate parent of the EFH Corp. consolidated group, while each of EFIH, Oncor Holdings, EFCH and TCEH were classified as a disregarded entity for US federal income tax purposes. Pursuant to applicable US Treasury regulations and published guidance of the IRS, corporations that are members of a consolidated group have joint and several liability for the taxes of such group. Subsequent to the Effective Date, the TCEH Debtors and the Contributed EFH Debtors are no longer included in the consolidated federal income tax return of EFH Corp. and will be included in Vistra Energy's consolidated federal income tax return. 63 Prior to the Effective Date, EFH Corp. and certain of its subsidiaries (including EFCH, EFIH, and TCEH, but not including Oncor Holdings and Oncor) were parties to a Federal and State Income Tax Allocation Agreement, which provided, among other things, that any corporate member or disregarded entity in the EFH Corp. group is required to make payments to EFH Corp. in an amount calculated to approximate the amount of tax liability such entity would have owed if it filed a separate corporate tax return. Pursuant to the Plan of Reorganization, the TCEH Debtors and the Contributed EFH Debtors rejected this agreement on the Effective Date. See Notes 2 and 10 for a discussion of the Tax Matters Agreement that was entered into on the Effective Date between EFH Corp. and Vistra Energy. Additionally, since the date of the Settlement Agreement, no further cash payments among the Debtors were made in respect of federal income taxes. The Settlement Agreement did not alter the allocation and payment for state income taxes, which continued to be settled prior to the Effective Date. Income Tax Expense (Benefit) The components of our income tax expense (benefit) are as follows: Current: US Federal State Total current Deferred: US Federal State Total deferred Total Successor Predecessor Period from October 3, 2016 through December 31, 2016 Period from January 1, 2016 through October 2, 2016 Year Ended December 31, 2015 2014 $ $ — $ 6 6 (75) (1) (76) (70) $ (6) $ 9 3 (1,234) (36) (1,270) (1,267) $ (17) $ 21 4 (811) (72) (883) (879) $ 30 28 58 (2,361) (17) (2,378) (2,320) Reconciliation of income taxes computed at the US federal statutory rate to income tax benefit recorded: Income (loss) before income taxes Income taxes at the US federal statutory rate of 35% Nondeductible TRA accretion IRS audit and appeals settlements Nondeductible goodwill impairment Texas margin tax, net of federal benefit Lignite depletion allowance Interest accrued for uncertain tax positions, net of tax Nondeductible interest expense Nondeductible debt restructuring costs Valuation allowance Nontaxable gain on extinguishment of LSTC Other Income tax benefit Effective tax rate Successor Period from October 3, 2016 through December 31, 2016 (233) $ (82) 5 — — 3 — — — 2 — — 2 (70) 30.0% $ 64 Period from January 1, 2016 through October 2, 2016 $ 21,584 7,554 — — — (21) — — 12 38 (210) (8,593) (47) (1,267) $ (5.9)% Predecessor Year Ended December 31, $ $ 2015 (5,556) (1,945) — — 770 — (8) (2) 21 64 210 — 11 (879) 15.8% $ $ 2014 (8,549) (2,992) — 53 560 10 (14) — 21 42 — — — (2,320) 27.1% Deferred Income Tax Balances Deferred income taxes provided for temporary differences based on tax laws in effect at December 31, 2016 and 2015 are as follows: Noncurrent Deferred Income Tax Assets Alternative minimum tax credit carryforwards Net operating loss (NOL) carryforwards Unfavorable purchase and sales contracts Commodity contracts and interest rate swaps Property, plant and equipment Intangible assets Debt extinguishment gains Employee benefit obligations Other Total deferred tax assets Noncurrent Deferred Income Tax Liabilities Property, plant and equipment Identifiable intangible assets Accrued interest Total deferred tax liabilities Valuation allowance Net Deferred Income Tax (Asset) Liability Successor Successor Predecessor December 31, 2016 December 31, 2015 $ $ — $ 8 — — 943 29 52 84 6 1,122 — — — — — (1,122) $ 22 440 193 125 — — 1,109 51 55 1,995 1,541 320 138 1,999 209 213 At December 31, 2016, we had total deferred tax assets of approximately $1.1 billion that was substantially comprised of book and tax basis differences related to our generation and mining property, plant and equipment. As of December 31, 2016, we assessed the need for a valuation allowance related to our deferred tax asset and considered both positive and negative evidence related to the likelihood of realization of the deferred tax assets. In connection with that analysis, we concluded that it is more likely than not that the deferred tax assets would be fully utilized by future taxable income, and thus, no valuation allowance was recognized. At December 31, 2016, we had $21 million in net operating loss (NOL) carryforwards for federal income tax purposes that will expire in 2037. At December 31, 2016, we had no alternative minimum tax (AMT) credit carryforwards available. The income tax effects of the components included in accumulated other comprehensive income totaled a net deferred tax liability of $3 million at December 31, 2016. Predecessor At December 31, 2015 our Predecessor had $1.257 billion in net operating loss (NOL) carryforwards for federal income tax purposes that will expire between 2035 and 2036. Audit settlements reached in 2013 resulted in the elimination of substantially all NOL carryforwards generated through 2013 and available AMT credits. The NOL carryforwards can be used to offset future taxable income. Our Predecessor believed that it was more likely than not that the full tax benefit from the NOLs would not be realized. In recognition of this risk, our Predecessor recorded a valuation allowance of $209 million on the net deferred tax assets balance at December 31, 2015. In assessing the need for the valuation allowance, our Predecessor considered both positive and negative evidence related to the likelihood of realization of the deferred tax assets. As a result of our Predecessor's assessment, it was concluded that there was uncertainty as to whether the current deferred tax assets (other than our Predecessor's indefinite lived deferred tax assets) would be fully utilized by future reversals of existing taxable temporary differences. 65 During 2015, our Predecessor's deferred tax liabilities related to property, plant and equipment were significantly reduced due to impairment charges on certain long-lived assets recorded in those periods. See Note 8 for a discussion of impairment charges. Additionally, our deferred tax liabilities related to debt fair value discounts were eliminated due to the write-off of unamortized deferred debt issuance and extension costs, premiums and discounts previously classified as LSTC. The income tax effects of the components included in accumulated other comprehensive income totaled a net deferred tax asset of $18 million at December 31, 2015. Liability for Uncertain Tax Positions Accounting guidance related to uncertain tax positions requires that all tax positions subject to uncertainty be reviewed and assessed with recognition and measurement of the tax benefit based on a "more-likely-than-not" standard with respect to the ultimate outcome, regardless of whether this assessment is favorable or unfavorable. Successor Vistra Energy and its subsidiaries file income tax returns in US federal and state jurisdictions and are expected to be subject to examinations by the IRS and other taxing authorities. Vistra Energy is not currently under audit for any period, and we have no uncertain tax positions at December 31, 2016. Predecessor EFH Corp. and its subsidiaries file or have filed income tax returns in US Federal, state and foreign jurisdictions and are subject to examinations by the IRS and other taxing authorities. Examinations of income tax returns filed by EFH Corp. and any of its subsidiaries for the years ending prior to January 1, 2015 are complete. The IRS chose not to audit the tax return filed by EFH Corp. for the 2015 tax year, and the federal income tax return for the 2016 tax year has not yet been filed. Texas franchise and margin tax return examinations have been completed. In September 2016, EFH Corp. entered into a settlement agreement with the Texas Comptroller of Public Accounts (Comptroller) whereby the Comptroller agreed to release all claims and liabilities related to the EFH Corp. consolidated group's state taxes, including sales tax, gross receipts utility tax, franchise tax and direct pay tax, through the agreement date, in exchange for a release of all refund claims and a one-time payment of $12 million. This settlement was entered and approved by the Bankruptcy Court in September 2016. As a result of the settlement, our Predecessor reduced the liability for uncertain tax positions by $27 million. In July 2016, EFH Corp. executed a Revenue Agent Report (RAR) with the IRS for the 2010 through 2013 tax years. As a result of the RAR, our Predecessor reduced the liability for uncertain tax positions by $1 million, resulting in a reclassification to the accumulated deferred income tax liability. Total cash payment to be assessed by the IRS for tax years 2010 through 2013, but not expected to be paid during the pendency of the Chapter 11 Cases of the EFH Debtors, is approximately $15 million, plus any interest that may be assessed. In March 2016, EFH Corp. signed a RAR with the IRS for the 2014 tax year. No financial statement impacts resulted from the signing of the 2014 RAR. In June 2015, EFH Corp. signed a RAR with the IRS for the 2008 and 2009 tax years. The Bankruptcy Court approved EFH Corp.'s signing of the RAR in July 2015. As a result of EFH Corp. signing this RAR, our Predecessor reduced the liability for uncertain tax positions by $22 million, resulting in a $18 million increase in noncurrent inter-company tax payable to EFH Corp., a $2 million reclassification to the accumulated deferred income tax liability and the recording of a $2 million income tax benefit. Total cash payment to be assessed by the IRS for tax years 2008 and 2009, but not paid during the pendency of the Chapter 11 Cases of the EFH Debtors, is approximately $15 million, plus any interest that may be assessed. In 2014, the IRS filed a claim with the Bankruptcy Court for open tax years through 2013 that was consistent with the settlement EFH Corp. reached with IRS Appeals for tax years 2003-2006. Also in 2014, EFH Corp. signed a final RAR with the IRS and associated documentation for the 2007 tax year. As a result of these events, EFH Corp. effectively settled the 2003-2007 open tax years, and our Predecessor reduced the liability for uncertain tax positions related to such years by $123 million, resulting in a $119 million reclassification to the accumulated deferred income tax liability and the recording of a $4 million income tax benefit reflecting the settlement of certain positions. 66 In recording the 2014 impacts, our Predecessor identified approximately $85 million of income tax expense related to 2013 which was recorded in December 2014. The impact of recording this expense was not material to the financial statements in 2013 or 2014. Our Predecessor classified interest and penalties related to uncertain tax positions as current income tax expense. Ongoing accruals of interest after the IRS settlements were not material in 2015 and 2014. Noncurrent liabilities of our Predecessor included a total of $4 million in accrued interest at December 31, 2015. The federal income tax benefit on the interest accrued on uncertain tax positions was recorded as accumulated deferred income taxes. The following table summarizes the changes to the uncertain tax positions, reported in other noncurrent liabilities in the consolidated balance sheets, during the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively: Balance at beginning of period, excluding interest and penalties Additions based on tax positions related to prior years Reductions based on tax positions related to prior years Additions based on tax positions related to the current year Settlements with taxing authorities Balance at end of period, excluding interest and penalties $ Tax Matters Agreement Period from January 1, 2016 through October 2, 2016 36 $ Predecessor Year Ended December 31, 2015 2014 $ 65 $ — (1) — (35) — $ — (11) — (18) 36 $ 184 55 (155) — (19) 65 On the Effective Date, we entered into a Tax Matters Agreement (the Tax Matters Agreement), with EFH Corp. whereby the parties have agreed to take certain actions and refrain from taking certain actions in order to preserve the intended tax treatment of the Spin-Off and to indemnify the other parties to the extent a breach of such agreement results in additional taxes to the other parties. Among other things, the Tax Matters Agreement allocates the responsibility for taxes for periods prior to the Spin-Off between EFH Corp. and us. For periods prior to the Spin-Off: (a) Vistra Energy is generally required to reimburse EFH Corp. with respect to any taxes paid by EFH Corp. that are attributable to us and (b) EFH Corp. is generally required to reimburse us with respect to any taxes paid by us that are attributable to EFH Corp. We are also required to indemnify EFH Corp. against taxes, under certain circumstance, if the IRS or another taxing authority successfully challenges the amount of gain relating to the PrefCo Preferred Stock Sale or the amount or allowance of EFH Corp.'s net operating loss deductions. Subject to certain exceptions, the Tax Matters Agreement prohibits us from taking certain actions that could reasonably be expected to undermine the intended tax treatment of the Spin-Off or to jeopardize the conclusions of the private letter ruling we obtained from the IRS or opinions of counsel received by us or EFH Corp., in each case, in connection with the Spin-Off. Certain of these restrictions apply for two years after the Spin-Off. Under the Tax Matters Agreement, we may engage in an otherwise restricted action if (a) we obtain written consent from EFH Corp., (b) such action or transaction is described in or otherwise consistent with the facts in the private letter ruling we obtained from the IRS in connection with the Spin-Off, (c) we obtain a supplemental private letter ruling from the IRS, or (d) we obtain an unqualified opinion of a nationally recognized law or accounting firm that is reasonably acceptable to EFH Corp. that the action will not affect the intended tax treatment of the Spin-Off. 67 10. TAX RECEIVABLE AGREEMENT OBLIGATION On the Effective Date, Vistra Energy entered into a tax receivable agreement (the TRA) with a transfer agent on behalf of certain former first lien creditors of TCEH. The TRA generally provides for the payment by us to holders of TRA Rights of 85% of the amount of cash savings, if any, in United States federal and state income tax that we realize in periods after Emergence as a result of (a) certain transactions consummated pursuant to the Plan of Reorganization (including any step-up in tax basis in our assets resulting from the PrefCo Preferred Stock Sale), (b) the tax basis of all assets acquired in connection with the Lamar and Forney Acquisition in April 2016 and (c) tax benefits related to imputed interest deemed to be paid by us as a result of payments under the TRA, plus interest accruing from the due date of the applicable tax return. Pursuant to the TRA, we issued the TRA Rights for the benefit of the first lien secured creditors of our Predecessor entitled to receive such TRA Rights under the Plan. Such TRA Rights are subject to various transfer restrictions described in the TRA and are entitled to certain registration rights more fully described in the Registration Rights Agreement. The estimate of fair value of $574 million for the Tax Receivable Agreement Obligation on the Effective Date was the discounted amount of projected payments under the TRA, based on certain assumptions, including but not limited to: • • the amount of tax basis step-up resulting from the PrefCo Preferred Stock Sale, which is expected to be approximately $5.5 billion, and the allocation of such tax basis step-up among the assets subject thereto; the depreciable lives of the assets subject to such tax basis step-up, which generally is expected to be 15 years for most of such assets; • a federal corporate income tax rate of 35%; • the Company will generally generate sufficient taxable income so as to be able to utilize the deductions arising out of (i) the tax basis step-up attributable to the PrefCo Preferred Stock Sale, (ii) the entire tax basis of the assets acquired as a result of the Lamar and Forney Acquisition (as defined herein), and (iii) tax benefits related to imputed interest deemed to be paid by us as a result of payments under the TRA in the tax year in which such deductions arise, and • a discount rate of 15%, which represents our view of the rate that a market participant would use based on the risk associated with the uncertainty in the amount and timing of the cash flows. The aggregate amount of undiscounted payments under the TRA is estimated to be approximately $2.1 billion, with more than 90% of such amount expected to be attributable to the first 15 tax years following Emergence, and the final payment expected to be made approximately 40 years following Emergence (assuming that the TRA is not terminated earlier pursuant to its terms). The fair value of the obligation at the Emergence Date is being accreted to the amount of the gross expected obligation using the effective interest method. Changes in the amount of this obligation resulting from changes to either the timing or amount of cash flows are recognized in the period of change and measured using the discount rate inherent in the initial fair value of the obligation. During the period from October 3, 2016 to December 31, 2016, the Impacts of Tax Receivable Agreement on the statement of consolidated income (loss) was $22 million, which represents accretion expense for the period, and the balance at December 31, 2016 totaled $596 million. Under the Internal Revenue Code, a corporation's ability to utilize certain tax attributes, including depreciation, may be limited following an ownership change if the corporation’s overall asset tax basis exceeds the overall fair market value of its assets (after making certain adjustments). The Spin-Off resulted in an ownership change and it is expected that the overall tax basis of our assets may have exceeded the overall fair market value of our assets at such time. As a result, there may be a limitation on our ability to claim a portion of our depreciation deductions for a five-year period. This limitation could have a material impact on our tax liabilities and on our obligations under the TRA Rights. In addition, any future ownership change of Vistra Energy following Emergence could likewise result in additional limitations on our ability to use certain tax attributes existing at the time of any such ownership change and have an impact on our tax liabilities and on our obligations with respect to the TRA Rights under the TRA. 68 11.

Of the $193 million, $127 million is included in the liability arising from the termination of TCEH interest swaps as discussed in Note 17. Predecessor Interest expense for the Predecessor period from January 1, 2016 through October 2, 2016, the year ended December 31, 2015 and the post-petition period ended December 31, 2014 reflects interest paid and accrued on debtor-in-possession financing (see Note 13), adequate protection amounts paid and accrued, as approved by the Bankruptcy Court in June 2014 for the benefit of secured creditors of (a) $22.616 billion principal amount of outstanding borrowings from the TCEH Senior Secured Facilities, (b) $1.750 billion principal amount of outstanding TCEH Senior Secured Notes and (c) the $1.243 billion net liability related to the TCEH first lien interest rate swaps and natural gas hedging positions terminated shortly after the Bankruptcy Filing (see Note 2), in exchange for their consent to the senior secured, super-priority liens contained in the DIP Facility and any diminution in value of their interests in the pre-petition collateral from the Petition Date. The interest rates applicable to the adequate protection amounts paid/accrued was 4.95%, 4.69% and 4.65% (one-month LIBOR plus 4.50%) for the Predecessor period from January 1, 2016 through October 2, 2016, the year ended December 31, 2015 and the post-petition period ended December 31, 2014, respectively. As of the Effective Date, amounts of adequate protection payments were re-characterized as payments of principal. The Bankruptcy Code generally restricts payment of interest on pre-petition debt, subject to certain exceptions. Other than amounts ordered or approved by the Bankruptcy Court, effective on the Petition Date, our Predecessor discontinued recording interest expense on outstanding pre-petition debt classified as LSTC. The table below shows contractual interest amounts, which were amounts due under the contractual terms of the outstanding debt, including debt subject to compromise during the Chapter 11 Cases. Interest expense reported in the statements of consolidated income (loss) does not include contractual interest on pre- petition debt classified as LSTC totaling $640 million, $897 million and $604 million for the Predecessor period from January 1, 2016 through October 2, 2016, the year ended December 31, 2015 and the post-petition period ended December 31, 2014, respectively, which had been stayed by the Bankruptcy Court effective on the Petition Date. Adequate protection paid/accrued presented below excludes interest paid/accrued on the TCEH first-lien interest rate and commodity hedge claims (see Note 17) totaling $47 million, $60 million and $40 million for the Predecessor period from January 1, 2016 through October 2, 2016, the year ended December 31, 2015 and the post-petition period ended December 31, 2014, respectively, as such amounts are not included in contractual interest amounts below.

This subsidiary's preferred stock is accounted for as a debt instrument under relevant accounting guidance. (c) Obligation related to a corporate office space capital lease contributed to Vistra Energy pursuant to the Plan of Reorganization. This obligation will be funded by amounts held in an escrow account and reflected in other noncurrent assets on the consolidated balance sheet at December 31, 2016. Vistra Operations Credit Facilities — As of the Effective Date, the Vistra Operations Credit Facilities initially consisted of up to $4.250 billion in senior secured, first lien financing consisting of a revolving credit facility of up to $750 million, including a $500 million letter of credit sub-facility (Initial Revolving Credit Facility), a term loan facility of up to $2.850 billion (Initial Term Loan B Facility) and a term loan letter of credit facility of up to $650 million (Term Loan C Facility). 70 In December 2016, we incurred $1 billion of incremental term loans (Incremental Term Loan B Facility, and together with the Initial Term Loan B Facility, the Term Loan B Facility) and $110 million of incremental revolving credit commitments (Incremental Revolving Credit Facility, and together with the Initial Revolving Credit Facility, the Revolving Credit Facility). The letter of credit sub-facility was also increased from $500 million to $600 million. Proceeds from the Incremental Term Loan B Facility were used to fund the special cash dividend in the aggregate amount of $1 billion that was approved by Vistra Energy's board of directors and paid in December 2016 (see Note 15). The Vistra Operations Credit Facilities and related available capacity at December 31, 2016 are presented below.

(c) Facility used to fund a special cash dividend paid in December 2016 (see Note 15). (d) Facility used for issuing letters of credit for general corporate purposes. Borrowings under this facility were funded to collateral accounts that are reported as restricted cash in the consolidated balance sheet. At December 31, 2016, the restricted cash supported $519 million in letters of credit outstanding (see Note 22), leaving $131 million in available letter of credit capacity. As of December 31, 2016, amounts borrowed under the Revolving Credit Facility would bear interest based on applicable LIBOR rates plus 3.25%, and there were no outstanding borrowings at December 31, 2016. As of December 31, 2016, amounts borrowed under the Initial Term Loan B Facility and the Term Loan C Facility bear interest based on applicable LIBOR rates, subject to a 1% floor, plus 4%, and the interest rate on outstanding borrowings was 5% at December 31, 2016. Amounts borrowed under the Incremental Term Loan B Facility bear interest based on applicable LIBOR rates, subject to a 0.75% floor, plus 3.25%, and the rate outstanding on outstanding borrowings was 4% at December 31, 2016. The Vistra Operation Credit Facilities also provides for certain additional fees payable to the agents and lenders, as well as availability fees payable with respect to any unused portions of the available Vistra Operations Credit Facilities. In February 2017, certain pricing terms for the Vistra Operations Credit Facility were amended. Any amounts borrowed under the Revolving Credit Facility will bear interest based on applicable LIBOR rates plus 2.75%. Amounts borrowed under the Initial Term Loan B Facility and the Term Loan C Facility will bear interest based on applicable LIBOR rates, subject to a 0.75% floor, plus 2.75%. We are required to make scheduled quarterly payments on the Term Loan B Facility in annual amounts equal to 1% of the original principal amount of the Term Loan B Facility with the balance paid at maturity. The first repayment will be made on March 31, 2017. Obligations under the Vistra Operations Credit Facilities are secured by a lien covering substantially all of Vistra Energy's consolidated assets, rights and properties, subject to certain exceptions set forth in the Vistra Operations Credit Facilities. The Vistra Operations Credit Facilities also permit certain hedging agreements to be secured on a pari-passu basis with the Vistra Operations Credit Facilities in the event those hedging agreements met certain criteria set forth in the Vistra Operations Credit Facilities. 71 The Vistra Operation Credit Facilities provide for affirmative and negative covenants applicable to Vistra Energy, including affirmative covenants requiring us to provide financial and other information to the agents under the Vistra Operations Credit Facilities and to not change our lines of business, and negative covenants restricting Vistra Energy's ability to incur additional indebtedness, make investments, dispose of assets, pay dividends, grant liens or take certain other actions, in each case except as permitted in the Vistra Operation Credit Facilities. Vistra Energy's ability to borrow under the Vistra Operations Credit Facilities is subject to the satisfaction of certain customary conditions precedent set forth therein. The Vistra Operations Credit Facilities provide for certain customary events of default, including events of default resulting from non-payment of principal, interest or fees when due, material breaches of representations and warranties, material breaches of covenants in the Vistra Operations Credit Facilities or ancillary loan documents, cross-defaults under other agreements or instruments and the entry of material judgments against Vistra Energy. Solely with respect to the Revolving Credit Facility, and solely during a compliance period (which, in general, is applicable when the aggregate revolving borrowings and issued revolving letters of credit (in excess of $100 million) exceed 30% of the revolving commitments), the agreement includes a covenant that requires the consolidated first lien net leverage ratio, which is based on the ratio of net first lien debt compared to an EBITDA calculation defined under the terms of the facilities, not exceed 4.25 to 1.00. Although we had no borrowings under the Revolving Credit Facility as of December 31, 2016, we would have been in compliance with this financial covenant if it were required to be tested. Upon the existence of an event of default, the Vistra Operations Credit Facilities provides that all principal, interest and other amounts due thereunder will become immediately due and payable, either automatically or at the election of specified lenders. Maturities — Long-term debt maturities at December 31, 2016 are as follows: 2017 2018 2019 2020 2021 Thereafter Unamortized premiums, discounts and debt issuance costs Total long-term debt including amounts due currently Successor December 31, 2016 46 $ 44 44 44 45 4,380 20 4,623 $ Interest Rate Swaps — In the Successor period from October 3, 2016 through December 31, 2016, we entered into $3.0 billion notional amount of interest rate swaps to hedge our exposure to our variable rate debt. The interest rate swaps, which become effective in January 2017, expire in July 2023 and, when taking into consideration the amended pricing on the Vistra Operations Credit Facilities discussed above, effectively fix the interest rates between 4.67% and 4.91%. The interest rate swaps are secured by a first lien secured interest on a pari-passu basis with the Vistra Operations Credit Facilities. Predecessor DIP Roll Facilities — In August 2016, the Predecessor entered into the DIP Roll Facilities. The facilities provided for up to $4.250 billion in senior secured, super-priority financing consisting of a revolving credit facility of up to $750 million (DIP Roll Revolving Credit Facility), a term loan letter of credit facility of up to $650 million (DIP Roll Letter of Credit Facility) and a term loan facility of up to $2.850 billion (DIP Roll Term Loan Facility). The DIP Roll Facilities were senior, secured, super- priority debtor-in-possession credit agreements by and among the TCEH Debtors, the lenders that were party thereto from time to time and an administrative and collateral agent. The maturity date of the DIP Roll Facilities was the earlier of (a) October 31, 2017 or (b) the Effective Date. On the Effective Date, the DIP Roll Facilities converted to the Vistra Operations Credit Facilities discussed above. Net proceeds from the DIP Roll Facilities totaled $3.465 billion and were used to repay $2.65 billion outstanding under the former DIP Facility, fund a $650 million collateral account used to backstop the issuances of letters of credit and pay $107 million of issuance costs. The remaining balance was used for general corporate purposes. Additionally, $800 million of cash from collateral accounts under the former DIP Facility that was used to backstop letters of credit was released to the Predecessor to be used for general corporate purposes. 72 DIP Facility — The DIP Facility provided for up to $3.375 billion in senior secured, super-priority financing consisting of a revolving credit facility of up to $1.950 billion (DIP Revolving Credit Facility) and a term loan facility of up to $1.425 billion (DIP Term Loan Facility). The DIP Facility was a senior, secured, super-priority credit agreement by and among the TCEH Debtors, the lenders that were party thereto and an administrative and collateral agent. At December 31, 2015, all $1.425 billion of the DIP Term Loan Facility were borrowed at an interest rate of 3.75%. Of this amount, $800 million represented amounts that supported issuances of letters of credit that were funded to a collateral account. Of the collateral account at December 31, 2015, $281 million was reported as cash and cash equivalents and $519 million was reported as restricted cash, which represented the amounts of outstanding letters of credit. At December 31, 2015, no amounts were borrowed under the DIP Revolving Credit Facility. As discussed above, in August 2016 all amounts under the DIP Facility were repaid using proceeds from the DIP Roll Facilities, and the $800 million of cash that was funded to the collateral account was released to TCEH to be used for general corporate purposes. Other Long-Term Debt — Amounts in the Predecessor period represent pre-petition liabilities of the Predecessor that were not subject to compromise due to the debt being fully collateralized or specific orders from the Bankruptcy Court approving repayment of the debt. 7.48% Fixed Secured Facility Bonds with amortizing payments through January 2017 (a) Capital lease and other obligations Total Less amounts due currently Total long-term debt not subject to compromise ____________ (a) Debt issued by trust and secured by assets held by the trust.

COMMITMENTS AND CONTINGENCIES Contractual Commitments At December 31, 2016, we had contractual commitments under energy-related contracts, leases and other agreements as follows. 2017 2018 2019 2020 2021 Thereafter Total Coal purchase and transportation agreements 338 $ — — — — — 338 $ Pipeline transportation and storage reservation fees Nuclear Fuel Contracts Other Contracts $ $ 30 21 22 22 22 161 278 $ $ 72 91 39 43 49 222 516 $ $ 128 55 57 54 36 350 680 Amounts in other contracts include certain long-term service and maintenance contracts related to our generation assets. The table above excludes TRA and pension and OPEB plan payments due to the uncertainty in the timing of those payments. Expenditures under our coal purchase and coal transportation agreements totaled $109 million, $139 million, $218 million and $348 million for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. At December 31, 2016, future minimum lease payments under both capital leases and operating leases are as follows: 2017 2018 2019 2020 2021 Thereafter Total future minimum lease payments Less amounts representing interest Present value of future minimum lease payments Less current portion Long-term capital lease obligation Capital Leases Operating Leases (a) 25 $ 17 14 12 9 153 230 $ 2 — — — — — 2 — 2 (2) — $ $ ___________ (a) Includes operating leases with initial or remaining noncancellable lease terms in excess of one year.

Guarantees We have entered into contracts that contain guarantees to unaffiliated parties that could require performance or payment under certain conditions. As of December 31, 2016, there are no material outstanding claims related to our guarantee obligations, and we do not anticipate we will be required to make any material payments under these guarantees. 74 Letters of Credit At December 31, 2016, we had outstanding letters of credit under the Vistra Operations Credit Facilities totaling $519 million as follows: • • • • $363 million to support commodity risk management and trading collateral requirements in the normal course of business, including over-the-counter and exchange-traded hedging transactions and collateral postings with ERCOT; $70 million to support executory contracts and insurance agreements; $55 million to support our REP financial requirements with the PUCT, and $31 million for other credit support requirements. Litigation Litigation Related to EPA Reviews — In June 2008, the EPA issued an initial request for information to Luminant under the EPA's authority under Section 114 of the Clean Air Act (CAA). The stated purpose of the request is to obtain information necessary to determine compliance with the CAA, including New Source Review standards and air permits issued by the TCEQ for the Big Brown, Monticello and Martin Lake generation facilities. In April 2013, Luminant received an additional information request from the EPA under Section 114 related to our Big Brown, Martin Lake and Monticello facilities as well as an initial information request related to our Sandow 4 generation facility. In July 2012, the EPA sent Luminant a notice of violation alleging noncompliance with the CAA's New Source Review standards and the air permits at our Martin Lake and Big Brown generation facilities. In August 2013, the US Department of Justice, acting as the attorneys for the EPA, filed a civil enforcement lawsuit against Luminant in federal district court in Dallas, alleging violations of the CAA, including its New Source Review standards, at our Big Brown and Martin Lake generation facilities. In August 2015, the district court granted Luminant's motion to dismiss seven of the nine claims asserted by the EPA in the lawsuit. In August 2016, the EPA filed an amended complaint, eliminating one of the two remaining claims and withdrawing with prejudice a request for civil penalties in the other remaining claim. The EPA also filed a motion for entry of final judgment so that it could seek to appeal the district court's dismissal decision. In September 2016, Luminant filed a response opposing the EPA's motion for entry of final judgment. In October 2016, the district court denied the EPA's motion for entry of final judgment and agreed that the remaining claim must be fully adjudicated at the district court or withdrawn with prejudice before the EPA may appeal the dismissal decision. In January 2017, the EPA dismissed its two remaining claims with prejudice and the district court entered final judgment in our favor. In March 2017, the EPA appealed the final judgment to the Fifth Circuit Court and Luminant filed a motion in the district court to recover its attorney fees and costs. We believe that we and Luminant have complied with all requirements of the CAA and intend to vigorously defend against the remaining allegations. The lawsuit requests the maximum civil penalties available under the CAA to the government of up to $32,500 to $37,500 per day for each alleged violation, depending on the date of the alleged violation, and injunctive relief, including an order requiring the installation of best available control technology at the affected units. An adverse outcome could require substantial capital expenditures that cannot be determined at this time or retirement of the plants at issue and could possibly require the payment of substantial penalties. We cannot predict the outcome of these proceedings, including the financial effects, if any. 75 Greenhouse Gas Emissions In August 2015, the EPA finalized rules to address greenhouse gas (GHG) emissions from new, modified and reconstructed and existing electricity generation units, referred to as the Clean Power Plan. The rule for existing facilities would establish state- specific emissions rate goals to reduce nationwide CO2 emissions related to affected units by over 30% from 2012 emission levels by 2030. A number of parties, including Luminant, filed petitions for review in the US Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) for the rule for new, modified and reconstructed plants. In addition, a number of petitions for review of the rule for existing plants were filed in the D.C. Circuit Court by various parties and groups, including challenges from twenty- seven different states opposed to the rule as well as those from, among others, certain power generating companies, various business groups and some labor unions. Luminant also filed its own petition for review. In January 2016, a coalition of states, industry (including Luminant) and other parties filed applications with the US Supreme Court (Supreme Court) asking that the Supreme Court stay the rule while the D.C. Circuit Court reviews the legality of the rule for existing plants. In February 2016, the Supreme Court stayed the rule pending the conclusion of legal challenges on the rule before the D.C. Circuit Court and until the Supreme Court disposes of any subsequent petition for review. Oral argument on the merits of the legal challenges to the rule were heard in September 2016 before the entire D.C. Circuit Court. In March 2017, President Trump issued an Executive Order entitled Promoting Energy Independence and Economic Growth (Order). The Order covers a number of matters, including the Clean Power Plan. Among other provisions, the Order directs the EPA to review the Clean Power Plan and, if appropriate, suspend, revise or rescind the rules on existing and new, modified and reconstructed generating units. In addition, the Department of Justice has filed motions seeking to abate those cases until the EPA concludes its review of the rules, including any new rulemaking that results from that review. While we cannot predict the outcome of these rulemakings and related legal proceedings, or estimate a range of reasonably probable costs, if the rules are ultimately implemented or upheld as they were issued, they could have a material impact on our results of operations, liquidity or financial condition. In August 2015, the EPA proposed model rules and federal plan requirements for states to consider as they develop state plans to comply with the rules for GHG emissions. A federal plan would then be finalized for a state if a state fails to submit a state plan by the deadlines established in the Clean Power Plan for existing plants or if the EPA disapproves a submitted state plan. Luminant filed comments on the federal plan proposal and model rules in January 2016. The Executive Order issued in March 2017, directed the EPA to review this proposed rule for consistency with the policies in the Order and, if appropriate, to revise or withdraw the proposed rule. While we cannot predict the timing or outcome of this rulemaking and related legal proceedings, or estimate a range of reasonably possible costs, they could have a material impact on our results of operations, liquidity or financial condition. Cross-State Air Pollution Rule (CSAPR) In July 2011, the EPA issued the CSAPR, compliance with which would have required significant additional reductions of SO2 and NOx emissions from our fossil fueled generation units. In February 2012, the EPA released a final rule (Final Revisions) and a proposed rule revising certain aspects of the CSAPR, including increases in the emissions budgets for Texas and our generation assets as compared to the July 2011 version of the rule. In June 2012, the EPA finalized the proposed rule (Second Revised Rule). 76 The CSAPR became effective January 1, 2015. In July 2015, following a remand of the case from the Supreme Court to consider further legal challenges, the D.C. Circuit Court unanimously ruled in favor of Luminant and other petitioners, holding that the CSAPR emissions budgets over-controlled Texas and other states. The D.C. Circuit Court remanded those states' budgets to the EPA for prompt reconsideration. While Luminant planned to participate in the EPA's reconsideration process to develop increased budgets for the 1997 ozone standard that do not over-control Texas, the EPA instead responded to the remand by proposing a new rulemaking that created new NOX ozone season budgets for the 2008 ozone standard without addressing the over-controlling budgets for the 1997 standard. Comments on the EPA's proposal were submitted by Luminant in February 2016. In August 2016, the EPA disapproved Texas's 2008 ozone SIP submittal and imposed a FIP in its place in October 2016. Texas filed a petition in the Fifth Circuit Court challenging the SIP disapproval and Luminant has intervened in support of Texas's challenge. The State of Texas and Luminant have also both filed challenges in the D.C. Circuit Court challenging the EPA's FIP and those cases are currently pending before that court. With respect to Texas's SO2 emission budgets, in June 2016, the EPA issued a memorandum describing the EPA's proposed approach for responding to the D.C. Circuit Court's remand for reconsideration of the CSAPR SO2 emission budgets for Texas and three other states that had been remanded to the EPA by the D.C. Circuit Court. In the memorandum, the EPA stated that those four states could either voluntarily participate in the CSAPR by submitting a State Implementation Plan (SIP) revision adopting the SO2 budgets that had been previously held invalid by the D.C. Circuit Court and the current annual NOx budgets or, if the state chooses not to participate in the CSAPR, the EPA could withdraw the CSAPR Federal Implementation Plan (FIP) by the fall of 2016 for those states and address any interstate transport and regional haze obligations on a state-by-state basis. Texas has not indicated that it intends to adopt the over-controlling budgets and, in November 2016, the EPA proposed to withdraw the CSAPR FIP for Texas. Because the EPA has not finalized its proposal to remove Texas from the annual CSAPR programs, these programs will continue to apply to Texas and Texas sources. At this time, the EPA has not populated the allowance accounts for Texas sources with 2017 annual CSAPR program allowances. While we cannot predict the outcome of future proceedings related to the CSAPR, including the EPA's recent actions concerning the CSAPR annual emissions budgets for affected states and participating in the CSAPR program, based upon our current operating plans we do not believe that the CSAPR itself will cause any material operational, financial or compliance issues to our business or require us to incur any material compliance costs. Regional Haze — Reasonable Progress and Long-Term Strategies The Regional Haze Program of the CAA establishes "as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I federal areas, like national parks, which impairment results from man- made pollution." There are two components to the Regional Haze Program. First, states must establish goals for reasonable progress for Class I federal areas within the state and establish long-term strategies to reach those goals and to assist Class I federal areas in neighboring states to achieve reasonable progress set by those states towards a goal of natural visibility by 2064. In February 2009, the TCEQ submitted a SIP concerning regional haze (Regional Haze SIP) to the EPA. In December 2011, the EPA proposed a limited disapproval of the Regional Haze SIP due to its reliance on the Clean Air Interstate Rule (CAIR) instead of the EPA's replacement CSAPR program that the EPA proposed in July 2011. In August 2012, Luminant filed a petition for review in the Fifth Circuit Court challenging the EPA's limited disapproval of the Regional Haze SIP on the grounds that the CAIR continued in effect pending the D.C. Circuit Court's decision in the CSAPR litigation. In September 2012, Luminant filed a petition to intervene in a case filed by industry groups and other states and private parties in the D.C. Circuit Court challenging the EPA's limited disapproval and issuance of a FIP regarding the regional haze BART program. The Fifth Circuit Court case has since been transferred to the D.C. Circuit Court and consolidated with other pending BART program regional haze appeals. Briefing in the D.C. Circuit Court was completed in March 2017. In June 2014, the EPA issued requests for information under Section 114 of the CAA to Luminant and other generators in Texas related to the reasonable progress program. After releasing a proposed rule in November 2014 and receiving comments from a number of parties, including Luminant and the State of Texas in April 2015, the EPA released a final rule in January 2016 approving in part and disapproving in part Texas' SIP for Regional Haze and issuing a FIP for Regional Haze. In the rule, the EPA asserts that the Texas SIP does not show reasonable progress in improving visibility for two areas in Texas and that its long-term strategy fails to make emission reductions needed to achieve reasonable progress in improving visibility in the Wichita Mountains of Oklahoma. The EPA's proposed emission limits in the FIP assume additional control equipment for specific lignite/coal-fueled generation units across Texas, including new flue gas desulfurization systems (scrubbers) at seven electricity generating units and upgrades to existing scrubbers at seven electricity generating units. Specifically, for Luminant, the EPA's FIP is based on new scrubbers at Big Brown Units 1 and 2 and Monticello Units 1 and 2 and scrubber upgrades at Martin Lake Units 1, 2 and 3, Monticello Unit 3 and Sandow Unit 4. Luminant is continuing to evaluate the requirements and potential financial and operational impacts of the rule, but new scrubbers at the Big Brown and Monticello units necessary to achieve the emission limits required by the FIP (if those limits are possible to attain), along with the existence of low wholesale electricity prices in ERCOT, would likely challenge the long-term economic viability of those units. Under the terms of the rule, the scrubber upgrades will be required by February 2019, and the new scrubbers will be required by February 2021. 77 In March 2016, Luminant and a number of other parties, including the State of Texas, filed petitions for review in the US Fifth Circuit Court challenging the FIP's Texas requirements. Luminant and other parties also filed motions to stay the FIP while the court reviews the legality of the EPA's action. In July 2016, the Fifth Circuit Court denied the EPA's motion to dismiss Luminant's challenge to the FIP and denied the EPA's motion to transfer the challenges Luminant, the other industry petitioners and the State of Texas filed to the D.C. Circuit Court. In addition, the Fifth Circuit Court granted the motions to stay filed by Luminant, the other industry petitioners and the State of Texas pending final review of the petitions for review. The case was abated until the end of November 2016 in order to allow the parties to pursue settlement discussions. Settlement discussions were unsuccessful, and in December 2016 the EPA filed a motion seeking a voluntary remand of the rule back to the EPA for further consideration of Luminant's pending request for administrative reconsideration. Luminant and some of the other petitioners filed a response opposing the EPA's motion to remand and filed a cross motion for vacatur of the rule in December 2016. In March 2017, the Fifth Circuit Court remanded the rule back to the EPA for reconsideration in light of the Court's prior determination that we and the other petitioners demonstrated a substantial likelihood that the EPA exceeded its statutory authority and acted arbitrarily and capriciously, but the Court denied all of the other pending motions. The stay of the rule (and the emission control requirements) remains in effect. In addition, the Fifth Circuit Court denied the EPA's motion to lift the stay as to parts of the rule implicated in the EPA's subsequent BART proposal and the Court is retaining jurisdiction of the case and requiring the EPA to file status reports on its reconsideration every 15 days. While we cannot predict the outcome of the rulemaking and legal proceedings, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Regional Haze — Best Available Retrofit Technology The second part of the Regional Haze Program subjects electricity generation units built between 1962 and 1977, to best available retrofit technology (BART) standards designed to improve visibility if such units cause or contribute to impairment of visibility in a federal class I area. BART reductions of SO2 and NOX are required either on a unit-by-unit basis or are deemed satisfied by state participation in an EPA-approved regional trading program such as the CSAPR. In response to a lawsuit by environmental groups, the D.C. Circuit Court issued a consent decree in March 2012 that required the EPA to propose a decision on the Regional Haze SIP by May 2012 and finalize that decision by November 2012. The consent decree requires a FIP for any provisions that the EPA disapproves. The D.C. Circuit Court has amended the consent decree several times to extend the dates for the EPA to propose and finalize a decision on the Regional Haze SIP. The consent decree was modified in December 2015 to extend the deadline for the EPA to finalize action on the determination and adoption of requirements for BART for electricity generation. Under the amended consent decree, the EPA had until December 2016 to propose, and has until September 2017 to finalize, a FIP for BART for Texas electricity generation sources if the EPA determines that BART requirements have not been met. The EPA issued its proposed BART FIP for Texas in December 2016. The EPA's proposed emission limits assume additional control equipment for specific lignite/coal-fueled generation units across Texas, including new flue gas desulfurization systems (scrubbers) at 12 electric generation units and upgrades to existing scrubbers at four electric generation units. Specifically, for Luminant, the EPA's emission limitations are based on new scrubbers at Big Brown Units 1 and 2 and Monticello Units 1 and 2 and scrubber upgrades at Martin Lake Units 1, 2 and 3 and Monticello Unit 3. Luminant is continuing to evaluate the requirements and potential financial and operational impacts of the proposed rule, but new scrubbers at the Big Brown and Monticello units necessary to achieve the emission limits required by the FIP (if those limits are possible to attain), along with the existence of low wholesale power prices in ERCOT, would likely challenge the long-term economic viability of those units. Under the terms of the rule, the scrubber upgrades will be required within three years of the effective date of the final rule and the new scrubbers will be required within five years of the effective date of the final rule. We anticipate submitting comments on the proposed FIP when those are due in May 2017. While we cannot predict the outcome of the rulemaking and potential legal proceedings, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. 78 Intersection of the CSAPR and Regional Haze Programs Historically the EPA has considered compliance with a regional trading program, such as the CSAPR, as satisfying a state's obligations under the BART portion of the Regional Haze Program. However, in the reasonable progress FIP, the EPA diverged from this approach and did not treat Texas' compliance with the CSAPR as satisfying its obligations under the BART portion of the Regional Haze Program. The EPA concluded that it would not be appropriate to finalize that determination given the remand of the CSAPR budgets. As described above, the EPA has now proposed to remove Texas from the annual CSAPR trading programs. If Texas were in the CSAPR annual trading programs, the EPA would have no basis for its BART FIP because it has made a determination for Texas and all other states that participate in the CSAPR annual trading programs that such participation satisfies their BART obligations. We do not believe that EPA's proposal to remove Texas from the CSAPR annual trading programs satisfies the D.C. Circuit Court's mandate to the EPA to develop non-over-controlling budgets for Texas and we submitted comments on the EPA's proposed rule to remove Texas from the CSAPR annual trading programs. While we cannot predict the outcome of these matters, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Affirmative Defenses During Malfunctions In February 2013, in response to a petition for rulemaking filed by the Sierra Club, the EPA proposed a rule requiring certain states to replace SIP exemptions for excess emissions during malfunctions with an affirmative defense. Texas was not included in that original proposal since it already had an EPA-approved affirmative defense provision in its SIP that was found to be lawful by the Fifth Circuit Court in 2013. In 2014, as a result of a D.C. Circuit Court decision striking down an affirmative defense in another EPA rule, the EPA revised its 2013 proposal to extend the EPA's proposed findings of inadequacy to states that have affirmative defense provisions, including Texas. The EPA's revised proposal would require Texas to remove or replace its EPA- approved affirmative defense provisions for excess emissions during startup, shutdown and maintenance events. In May 2015, the EPA finalized the proposal. In June 2015, Luminant filed a petition for review in the Fifth Circuit Court challenging certain aspects of the EPA's final rule as they apply to the Texas SIP. The State of Texas and other parties have also filed similar petitions in the Fifth Circuit Court. In August 2015, the Fifth Circuit Court transferred the petitions that Luminant and other parties filed to the D.C. Circuit Court, and in October 2015 the petitions were consolidated with the pending petitions challenging the EPA's action in the D.C. Circuit Court. Briefing in the D.C. Circuit Court on the challenges was completed in October 2016 and oral argument is set for May 2017. We cannot predict the timing or outcome of this proceeding, or estimate a range of reasonably possible costs, but implementation of the rule as finalized may have a material impact on our results of operations, liquidity or financial condition. SO2 Designations for Texas In February 2016, the EPA notified Texas of the EPA's preliminary intention to designate nonattainment areas for counties surrounding our Big Brown, Monticello and Martin Lake generation plants based on modeling data submitted to the EPA by the Sierra Club. Such designation would potentially require the implementation of various controls or other requirements to demonstrate attainment. Luminant submitted comments challenging the use of modeling data rather than data from actual air quality monitoring equipment. In November 2016, the EPA finalized its proposed designations for Texas including finalizing the nonattainment designations for the areas referenced above. In doing so, the EPA ignored contradictory modeling that we submitted with our comments. The final designation mandates would be for Texas to begin the multi-year process to evaluate what potential emission controls or operational changes, if any, may be necessary to demonstrate attainment. In February 2017, the State of Texas and Luminant filed challenges to the nonattainment designations in the Fifth Circuit Court and protective petitions in the D.C. Circuit Court. In March 2017, the EPA filed a motion to transfer or dismiss our Fifth Circuit Court petition. In addition, Luminant has filed a request with the EPA to reconsider the rule and immediately stay its effective date. While we cannot predict the outcome of this matter, or estimate a range of reasonably possible costs, the result may have a material impact on our results of operations, liquidity or financial condition. Other Matters We are involved in various legal and administrative proceedings in the normal course of business, the ultimate resolutions of which, in the opinion of management, are not anticipated to have a material effect on our results of operations, liquidity or financial condition. 79 Labor Contracts We employ certain personnel who are represented by labor unions, the terms of whose employment are governed by collective bargaining agreements. During 2015, all collective bargaining agreements covering bargaining unit personnel engaged in lignite mining operations, lignite-, coal- and nuclear-fueled generation operations and some of our natural gas-fueled generation operations were extended to March 2017. While we cannot predict the outcome of labor contract negotiations, we do not expect any changes in collective bargaining agreements to have a material adverse effect on our results of operations, liquidity or financial condition. Nuclear Insurance Nuclear insurance includes nuclear liability coverage, property damage, decontamination and accidental premature decommissioning coverage and accidental outage and/or extra expense coverage. We maintain nuclear insurance that meets or exceeds requirements promulgated by Section 170 (Price-Anderson) of the Atomic Energy Act (the Act) and Title 10 of the Code of Federal Regulations. We intend to maintain insurance against nuclear risks as long as such insurance is available. We are self- insured to the extent that losses (i) are within the policy deductibles, (ii) are not covered per policy exclusions, terms and limitations, (iii) exceed the amount of insurance maintained, or (iv) are not covered due to lack of insurance availability. Any such self-insured losses could have a material adverse effect on our results of operations, liquidity or financial condition. With regard to liability coverage, the Act provides for financial protection for the public in the event of a significant nuclear generation plant incident. The Act sets the statutory limit of public liability for a single nuclear incident at $13.4 billion and requires nuclear generation plant operators to provide financial protection for this amount. However, the United States Congress could impose revenue-raising measures on the nuclear industry to pay claims that exceed the $13.4 billion limit for a single incident. As required, we insure against a possible nuclear incident at our Comanche Peak facility resulting in public nuclear-related bodily injury and property damage through a combination of private insurance and an industry-wide retrospective payment plan known as the Secondary Financial Protection (SFP). Under the SFP, in the event of any single nuclear liability loss in excess of $375 million at any nuclear generation facility in the United States, each operating licensed reactor in the United States is subject to an annual assessment of up to $127.3 million. This approximately $127.3 million maximum assessment is subject to increases for inflation every five years, with the next expected adjustment scheduled to occur in September 2018. Assessments are currently limited to $19 million per operating licensed reactor per year per incident. As of December 31, 2016, our maximum potential assessment under the industry retrospective plan would be approximately $254.6 million per incident but no more than $37.9 million in any one year for each incident. The potential assessment is triggered by a nuclear liability loss in excess of $375 million per accident at any nuclear facility. For losses after January 1, 2017, the potential assessment applies in excess of $450 million. The United States Nuclear Regulatory Commission (NRC) requires that nuclear generation plant license holders maintain at least $1.06 billion of nuclear decontamination and property damage insurance, and requires that the proceeds thereof be used to place a plant in a safe and stable condition, to decontaminate a plant pursuant to a plan submitted to, and approved by, the NRC prior to using the proceeds for plant repair or restoration, or to provide for premature decommissioning. We maintain nuclear decontamination and property damage insurance for our Comanche Peak facility in the amount of $2.25 billion and non-nuclear related property damage in the amount of $1.75 billion (subject to a $5 million deductible per accident except for natural hazards which are subject to a $9.5 million deductible per accident), above which we are self-insured. We also maintain Accidental Outage insurance to cover the additional costs of obtaining replacement electricity from another source if one or both of the units at our Comanche Peak facility are out of service for more than 20 weeks as a result of covered direct physical damage. Such coverage provides for weekly payments per unit of up to $5.25 million for the first 52 weeks, up to $4.35 million for the next 35 weeks and up to $3.6 million for the remaining 36 weeks, after the initial waiting period. The total maximum coverage is $393 million for non-nuclear accidents and $555 million for nuclear accidents. The coverage amounts applicable to each unit will be reduced to 80% if both units are out of service at the same time as a result of the same accident. 80 15. EQUITY Successor Shareholders' Equity Equity Issuances — As of December 31, 2016, 427,580,232 shares of Vistra Energy common stock were outstanding. On the Effective Date, 427,500,000 shares were issued pursuant to the Plan of Reorganization (see Note 2). Dividends Declared — In December 2016, the board of directors of Vistra Energy approved the payment of a special cash dividend (Special Dividend) in the aggregate amount of approximately $1 billion ($2.32 per share of common stock) to holders of record of our common stock on December 19, 2016. The dividend was funded using borrowings under the Vistra Operations Credit Facilities (see Note 13). Dividend Restrictions — The agreement governing the Vistra Operations Credit Facilities generally restricts our ability to make distributions or loans to any of our parent companies or their subsidiaries unless such distributions or loans were expressly permitted under the agreement governing such facility. Under applicable Delaware General Corporate Law, we are prohibited from paying any distribution to the extent that immediately following payment of such distribution, we would be insolvent. Accumulated Other Comprehensive Income — During the period from October 3, 2016 through December 31, 2016, we recorded a $6 million change in the funded status of our pension and other postretirement employee benefit liability; there were no amounts reclassified from accumulated other comprehensive income. Predecessor Membership Interests TCEH paid no dividends in the period from January 1, 2016 through October 2, 2016 nor the years ended December 31, 2015 and 2014. 16. FAIR VALUE MEASUREMENTS Accounting standards related to the determination of fair value define fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between willing market participants at the measurement date. We use a mid-market valuation convention (the mid-point price between bid and ask prices) as a practical expedient to measure fair value for the majority of our assets and liabilities subject to fair value measurement on a recurring basis. We primarily use the market approach for recurring fair value measurements and use valuation techniques to maximize the use of observable inputs and minimize the use of unobservable inputs. We categorize our assets and liabilities recorded at fair value based upon the following fair value hierarchy: • Level 1 valuations use quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 assets and liabilities include exchange-traded commodity contracts. the IntercontinentalExchange (ICE, an electronic commodity derivative exchange) futures and swaps transacted through clearing brokers for which prices are actively quoted. For example, some of our derivatives are NYMEX or • Level 2 valuations use inputs that, in the absence of actively quoted market prices, are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: (a) quoted prices for similar assets or liabilities in active markets, (b) quoted prices for identical or similar assets or liabilities in markets that are not active, (c) inputs other than quoted prices that are observable for the asset or liability such as interest rates and yield curves observable at commonly quoted intervals and (d) inputs that are derived principally from or corroborated by observable market data by correlation or other mathematical means. Our Level 2 valuations utilize over-the-counter broker quotes, quoted prices for similar assets or liabilities that are corroborated by correlations or other mathematical means, and other valuation inputs. For example, our Level 2 assets and liabilities include forward commodity positions at locations for which over-the-counter broker quotes are available. 81 • Level 3 valuations use unobservable inputs for the asset or liability. Unobservable inputs are used to the extent observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. We use the most meaningful information available from the market combined with internally developed valuation methodologies to develop our best estimate of fair value. For example, our Level 3 assets and liabilities include certain derivatives with values derived from pricing models that utilize multiple inputs to the valuations, including inputs that are not observable or easily corroborated through other means. See further discussion below. Our valuation policies and procedures were developed, maintained and validated by a centralized risk management group that reports to the Vistra Energy Chief Financial Officer. We utilize several different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those items that are measured on a recurring basis. These methods include, among others, the use of broker quotes and statistical relationships between different price curves. In utilizing broker quotes, we attempt to obtain multiple quotes from brokers (generally non-binding) that are active in the markets in which we participate (and require at least one quote from two brokers to determine a pricing input as observable); however, not all pricing inputs are quoted by brokers. The number of broker quotes received for certain pricing inputs varies depending on the depth of the trading market, each individual broker's publication policy, recent trading volume trends and various other factors. Probable loss from default by either us or our counterparties is considered in determining the fair value of derivative assets and liabilities. These non-performance risk adjustments take into consideration credit enhancements and the credit risks associated with our credit standing and the credit standing of our counterparties (see Note 17 for additional information regarding credit risk associated with our derivatives). We utilize credit ratings and default rate factors in calculating these fair value measurement adjustments. Certain derivatives and financial instruments are valued utilizing option pricing models that take into consideration multiple inputs including, but not limited to, commodity prices, volatility factors, discount rates and other market based factors. Additionally, when there is not a sufficient amount of observable market data, valuation models are developed that incorporate proprietary views of market factors. Significant unobservable inputs used to develop the valuation models include volatility curves, correlation curves, illiquid pricing locations and credit/non-performance risk assumptions. Those valuation models are generally used in developing long-term forward price curves for certain commodities, in particular, long-term ERCOT wholesale power prices. We believe the development of such curves is consistent with industry practice; however, the fair value measurements resulting from such curves are classified as Level 3. The significant unobservable inputs and valuation models are developed by employees trained and experienced in market operations and fair value measurements and validated by the company's risk management group, which also further analyzes any significant changes in Level 3 measurements. Significant changes in the unobservable inputs could result in significant upward or downward changes in the fair value measurement. With respect to amounts presented in the following fair value hierarchy tables, the fair value measurement of an asset or liability (e.g., a contract) is required to fall in its entirety in one level, based on the lowest level input that is significant to the fair value measurement. Certain assets and liabilities would be classified in Level 2 instead of Level 3 of the hierarchy except for the effects of credit reserves and non-performance risk adjustments, respectively. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability being measured. 82 Assets and liabilities measured at fair value on a recurring basis consisted of the following at the respective balance sheet dates shown below: Successor December 31, 2016 Level 1 Level 2 Level 3 (a) Reclassification (b) Total Assets: Commodity contracts Interest rate swaps Nuclear decommissioning trust – equity securities (c) Nuclear decommissioning trust – debt securities (c) Subtotal Assets measured at net asset value (d): Nuclear decommissioning trust - equity securities (c) Total assets Liabilities: Commodity contracts Interest rate swaps Total liabilities Assets: Commodity contracts Nuclear decommissioning trust – equity securities (c) Nuclear decommissioning trust – debt securities (c) Subtotal Assets measured at net asset value (d): Nuclear decommissioning trust – equity securities (c) Total assets Liabilities: Commodity contracts Total liabilities $ $ $ $ $ $ $ $ 167 — 425 — 592 302 — 302 $ $ $ $ 131 5 — 340 476 15 16 31 $ $ $ $ Predecessor December 31, 2015 98 — — — 98 15 — 15 $ $ $ $ — $ 13 — — 13 $ — $ 13 13 $ 396 18 425 340 1,179 247 1,426 332 29 361 Level 1 Level 2 Level 3 (a) Reclassification (b) Total 385 $ 41 $ 49 $ — $ 380 — 765 $ — 319 360 $ — — 49 $ 128 128 $ $ 64 64 $ $ 12 12 $ $ — — — $ — $ — $ 475 380 319 1,174 219 1,393 204 204 _______________ (a) See table below for description of Level 3 assets and liabilities. (b) Fair values are determined on a contract basis, but certain contracts result in a current asset and a noncurrent liability, or vice versa, as presented in the consolidated balance sheets. (c) The nuclear decommissioning trust investment is included in the investments line in the condensed consolidated balance sheets. See Note 22. (d) Certain investments measured at fair value using the net asset value per share (or its equivalent) have not been classified in the fair value hierarchy. The fair value amounts presented in this line are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the condensed consolidated balance sheets. Commodity contracts consist primarily of natural gas, electricity, fuel oil, uranium and coal agreements and include financial instruments entered into for hedging purposes as well as physical contracts that have not been designated normal purchases or sales.

See the table of changes in fair values of Level 3 assets and liabilities below for discussion of transfers between Level 2 and Level 3 for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014. During the Predecessor period from January 1, 2016 through October 2, 2016, in conjunction with the Lamar and Forney Acquisition, we acquired certain electricity spread options that are classified in Level 3 of the fair value hierarchy. The following table presents the changes in fair value of the Level 3 assets and liabilities for the Successor period from October 3, 2016 through December 31, 2016, the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014.

For the Successor period, substantially all changes in values of commodity contracts are reported in the statements of consolidated income (loss) in operating revenues or fuel, purchased power costs and delivery fees. For the Predecessor period, substantially all changes in values of commodity contracts (excluding net liabilities assumed in the Lamar and Forney Acquisition) are reported in the statements of consolidated income (loss) in net gain from commodity hedging and trading activities. 85 17. COMMODITY AND OTHER DERIVATIVE CONTRACTUAL ASSETS AND LIABILITIES Strategic Use of Derivatives We transact in derivative instruments, such as options, swaps, futures and forward contracts, to manage commodity price and interest rate risk. See Note 16 for a discussion of the fair value of derivatives. Commodity Hedging and Trading Activity — We utilize natural gas derivatives as hedging instruments designed to reduce exposure to changes in future electricity prices due to changes in the price of natural gas, thereby hedging future revenues from electricity sales from our generation assets. In ERCOT, the wholesale price of electricity has generally moved with the price of natural gas. We also enter into derivatives, including electricity, natural gas, fuel oil, uranium, emission and coal instruments, generally for short-term fuel hedging and other purposes. Unrealized gains and losses arising from changes in the fair value of hedging and trading instruments as well as realized gains and losses upon settlement of the instruments are reported in the statements of consolidated income (loss) in operating revenues and fuel, purchased power costs and delivery fees in the Successor period and net gain from commodity hedging and trading activities in the Predecessor periods. Interest Rate Swaps — Interest rate swap agreements are used to reduce exposure to interest rate changes by converting floating-rate interest rates to fixed rates, thereby hedging future interest costs and related cash flows. Unrealized gains and losses arising from changes in the fair value of the swaps as well as realized gains and losses upon settlement of the swaps are reported in the statements of consolidated income (loss) in interest expense and related charges. Termination of Predecessor's Commodity Hedges and Interest Rate Swaps — Commodity hedges and interest rate swaps entered into prior to the Petition Date are deemed to be forward contracts under the Bankruptcy Code. The Bankruptcy Filing constituted an event of default under these arrangements, and in accordance with the contractual terms, counterparties terminated certain positions shortly after the Bankruptcy Filing. The positions terminated consisted almost entirely of natural gas hedging positions and interest rate swaps that were secured by a first-lien interest in the same assets of TCEH on a pari passu basis with the TCEH Senior Secured Facilities and the TCEH Senior Secured Notes. Entities with a first-lien security interest included counterparties to both our Predecessor's natural gas hedging positions and interest rate swaps, which had entered into master agreements that provided for netting and setoff of amounts related to these positions. Additionally, certain counterparties to only our Predecessor's interest rate swaps hold the same first-lien security interest. The total net liability of $1.243 billion as of December 31, 2015 was reported in the consolidated balance sheets as a liability subject to compromise. Additionally, prior to the Effective Date, counterparties associated with the net liability were allowed, and had been receiving, adequate protection payments related to their claims as permitted by TCEH's cash collateral order approved by the Bankruptcy Court (see Note 11). Financial Statement Effects of Derivatives Substantially all derivative contractual assets and liabilities are accounted for under mark-to-market accounting consistent with accounting standards related to derivative instruments and hedging activities. The following tables provide detail of derivative contractual assets and liabilities as reported in the consolidated balance sheets at December 31, 2016 and 2015. Derivative asset and liability totals represent the net value of the contract, while the balance sheet totals represent the gross value of the contract. Successor December 31, 2016 Derivative Assets Derivative Liabilities Commodity contracts Interest rate swaps Commodity contracts Interest rate swaps Total $ $ 350 46 — — 396 $ $ — $ 17 (12) — 5 $ — $ — (330) (2) (332) $ — $ 1 (17) — (16) $ 350 64 (359) (2) 53 Current assets Noncurrent assets Current liabilities Noncurrent liabilities Net assets (liabilities) 86 Predecessor December 31, 2015 Derivative Assets Derivative Liabilities Commodity contracts Interest rate swaps Commodity contracts Interest rate swaps Total $ $ 465 10 — — 475 $ $ — $ — — — — $ — $ — (203) (1) (204) $ — $ — — — — $ 465 10 (203) (1) 271 Current assets Noncurrent assets Current liabilities Noncurrent liabilities Net assets (liabilities) At December 31, 2016 and 2015, there were no derivative positions accounted for as cash flow or fair value hedges. The following table presents the pretax effect of derivatives on net income (gains (losses)), including realized and unrealized effects: Successor Predecessor Derivative (statements of consolidated income (loss) presentation) Commodity contracts (Operating revenues) (a) Commodity contracts (Fuel, purchased power costs and delivery fees) (a) Commodity contracts (Net gain (loss) from commodity hedging and trading activities) (a) Interest rate swaps (Interest expense and related charges) (b) Interest rate swaps (Reorganization items) (Note 4) Net gain (loss) $ Period from October 3, 2016 through December 31, 2016 (92) $ Period from January 1, 2016 through October 2, 2016 $ — $ Year Ended December 31, 2015 2014 — $ — 380 — — 380 $ — — 17 (128) (277) (388) 21 — (11) — (82) $ — 194 — — 194 $ ____________ (a) Amount represents changes in fair value of positions in the derivative portfolio during the period, as realized amounts related to positions settled are assumed to equal reversals of previously recorded unrealized amounts. (b) Includes unrealized mark-to-market net gain (loss) as well as the net realized effect on interest paid/accrued, both reported in Interest Expense and Related Charges (see Note 11). The pretax effect (all losses) on net income and other comprehensive income (OCI) of derivative instruments previously accounted for as cash flow hedges were immaterial in the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014. There were no amounts recognized in OCI for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014. Accumulated other comprehensive income related to cash flow hedges at December 31, 2015 totaled $33 million in net losses (after-tax), substantially all of which related to interest rate swaps previously accounted for as cash flow hedges. In conjunction with fresh start reporting (see Note 3), the balances in accumulated other comprehensive income were eliminated from the consolidated balance sheet on the Effective Date. Balance Sheet Presentation of Derivatives Consistent with elections under US GAAP to present amounts on a gross basis, we report derivative assets and liabilities in the consolidated balance sheets without taking into consideration netting arrangements we have with counterparties to those derivatives. We may enter into offsetting positions with the same counterparty, resulting in both assets and liabilities. Volatility in underlying commodity prices can result in significant changes in derivative assets and liabilities presented from period to period. Margin deposits that contractually offset these derivative instruments are reported separately in the condensed consolidated balance sheets. Margin deposits received from counterparties are either used for working capital or other general corporate purposes or, if there are restrictions on the use of cash, amounts are deposited in a separate restricted cash account. At December 31, 2016 and 2015, essentially all margin deposits held were unrestricted. 87 We maintain standardized master netting agreements with certain counterparties that allow for the netting of positive and negative exposures. These agreements contain credit enhancements that allow for the right to offset assets and liabilities and collateral received in order to reduce credit exposure between us and the counterparty. These agreements contain specific language related to margin requirements, monthly settlement netting, cross-commodity netting and early termination netting, which is negotiated with the contract counterparty. The following tables reconcile our derivative assets and liabilities as presented in the condensed consolidated balance sheets to net amounts after taking into consideration netting arrangements with counterparties and financial collateral: Successor December 31, 2016 Predecessor December 31, 2015 Amounts Presented in Balance Sheet Offsetting Instruments (a) Financial Collateral (Received) Pledged (b) Net Amounts Amounts Presented in Balance Sheet Offsetting Instruments (a) Financial Collateral (Received) Pledged (b) Net Amounts Derivative assets: Commodity contracts $ Interest rate swaps Total derivative assets Derivative liabilities: Commodity contracts Interest rate swaps Total derivative liabilities 396 5 401 (332) (16) (348) $ (193) $ — (20) $ — (193) (20) 193 — 193 136 — 136 $ 183 5 188 (3) (16) (19) 475 — 475 (204) — (204) $ (145) $ — (147) $ — (145) (147) 145 — 145 6 — 6 183 — 183 (53) — (53) Net amounts $ 53 $ — $ 116 $ 169 $ 271 $ — $ (141) $ 130 ____________ (a) Amounts presented exclude trade accounts receivable and payable related to settled financial instruments.

(b) Represents gross forward purchases associated with instruments used to hedge electricity price differences between settlement points within ERCOT. (c) Successor period includes notional amounts of interest rate swaps that become effective in January 2017 and have maturity dates through July 2023. 88 Credit Risk-Related Contingent Features of Derivatives The agreements that govern our derivative instrument transactions may contain certain credit risk-related contingent features that could trigger liquidity requirements in the form of cash collateral, letters of credit or some other form of credit enhancement. Certain of these agreements require the posting of collateral if our credit rating is downgraded by one or more credit rating agencies. At December 31, 2016 and 2015, the fair value of liabilities related to derivative instruments under agreements with credit risk-related contingent features that were not fully collateralized totaled $13 million and $58 million, respectively. The liquidity exposure associated with these liabilities was reduced by cash and letter of credit postings with counterparties totaling $1 million and $31 million at December 31, 2016 and 2015, respectively. If all the credit risk-related contingent features related to these derivatives had been triggered, including cross-default provisions, remaining liquidity requirements would be immaterial at both December 31, 2016 and 2015. In addition, certain derivative agreements include cross-default provisions that could result in the settlement of such contracts if there were a failure under other financing arrangements to meet payment terms or to comply with other covenants that could result in the acceleration of such indebtedness. At December 31, 2016 and 2015, the fair value of derivative liabilities subject to such cross-default provisions totaled $18 million and $1 million, respectively. At December 31, 2016 and 2015, no cash collateral or letters of credit were posted with these counterparties, and the liquidity exposure associated with these liabilities totaled $17 million and zero at December 31, 2016 and 2015, respectively. As discussed immediately above, the aggregate fair values of liabilities under derivative agreements with credit risk-related contingent features, including cross-default provisions, totaled $31 million and $59 million at December 31, 2016 and 2015, respectively. These amounts are before consideration of cash and letter of credit collateral posted, net accounts receivable and derivative assets under netting arrangements and assets subject to related liens. Some commodity derivative contracts contain credit risk-related contingent features that do not provide for specific amounts to be posted if the features are triggered. These provisions include material adverse change, performance assurance, and other clauses that generally provide counterparties with the right to request additional credit enhancements. The amounts disclosed above exclude credit risk-related contingent features that do not provide for specific amounts or exposure calculations. Concentrations of Credit Risk Related to Derivatives We have concentrations of credit risk with the counterparties to our derivative contracts. At December 31, 2016, total credit risk exposure to all counterparties related to derivative contracts totaled $555 million (including associated accounts receivable). The net exposure to those counterparties totaled $306 million at December 31, 2016 after taking into effect netting arrangements, setoff provisions and collateral, with the largest net exposure to a single counterparty totaling $88 million. At December 31, 2016, the credit risk exposure to the banking and financial sector represented 59% of the total credit risk exposure and 39% of the net exposure. Exposure to banking and financial sector counterparties is considered to be within an acceptable level of risk tolerance because all of this exposure is with counterparties with investment grade credit ratings. However, this concentration increases the risk that a default by any of these counterparties would have a material effect on our financial condition, results of operations and liquidity. The transactions with these counterparties contain certain provisions that would require the counterparties to post collateral in the event of a material downgrade in their credit rating. We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies authorize specific risk mitigation tools including, but not limited to, use of standardized master agreements that allow for netting of positive and negative exposures associated with a single counterparty. Credit enhancements such as parent guarantees, letters of credit, surety bonds, liens on assets and margin deposits are also utilized. Prospective material changes in the payment history or financial condition of a counterparty or downgrade of its credit quality result in the reassessment of the credit limit with that counterparty. The process can result in the subsequent reduction of the credit limit or a request for additional financial assurances. An event of default by one or more counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts are owed to the counterparties related to the derivative contracts or delays in receipts of expected settlements if the counterparties owe amounts to us. 89 18. PENSION AND OTHER POSTRETIREMENT EMPLOYEE BENEFITS (OPEB) PLANS On the Effective Date, the EFH Retirement Plan was transferred to Vistra Energy pursuant to a separation agreement between Vistra Energy and EFH Corp. As of the Effective Date, Vistra Energy is the plan sponsor of the Vistra Retirement Plan (the Retirement Plan), which provides benefits to eligible employees of its subsidiaries. Oncor is a participant in the Retirement Plan. As Vistra Energy accounts for its interests in the Retirement Plan as a multiple employer plan, only Vistra Energy's share of the plan assets and obligations are reported in the pension benefit information presented below. After amendments in 2012, employees in the Retirement Plan now consist entirely of active and retired collective bargaining unit employees. The Retirement Plan is a qualified defined benefit pension plan under Section 401(a) of the Internal Revenue Code of 1986, as amended (Code), and is subject to the provisions of ERISA. The Retirement Plan provides benefits to participants under one of two formulas: (i) a Cash Balance Formula under which participants earn monthly contribution credits based on their compensation and a combination of their age and years of service, plus monthly interest credits or (ii) a Traditional Retirement Plan Formula based on years of service and the average earnings of the three years of highest earnings. Under the Cash Balance Formula, future increases in earnings will not apply to prior service costs. It is our policy to fund the Retirement Plan assets only to the extent deductible under existing federal tax regulations. Vistra Energy offers other postretirement employee benefits (OPEB) in the form of health care and life insurance to eligible employees of its subsidiaries and their eligible dependents upon the retirement of such employees. Vistra Energy is the sponsor of an OPEB plan that EFH Corp. participates in, and Oncor is the sponsor of an OPEB plan that Vistra Energy participates in. As Vistra Energy accounts for its interest in these OPEB plans as multiple employer plans, only Vistra Energy's share of the plan assets and obligations are reported in postretirement benefits other than pension information presented below. For employees retiring on or after January 1, 2002, the retiree contributions required for such coverage vary based on a formula depending on the retiree's age and years of service.

We include the realized and unrealized gains or losses in the market-related value of assets over a rolling four-year period. Each year, 25% of such gains and losses for the current year and for each of the preceding three years is included in the market-related value. Each year, the market-related value of assets is increased for contributions to the plan and investment income and is decreased for benefit payments and expenses for that year. 90 Detailed Information Regarding Pension Benefits The following information is based on a December 31, 2016 measurement date: Assumptions Used to Determine Net Periodic Pension Cost: Discount rate Expected return on plan assets Expected rate of compensation increase Components of Net Pension Cost: Service cost Interest cost Expected return on assets Net periodic pension cost Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Income: Net gain Total recognized in net periodic benefit cost and other comprehensive income Assumptions Used to Determine Benefit Obligations: Discount rate Expected rate of compensation increase Change in Pension Obligation: Projected benefit obligation at beginning of period Service cost Interest cost Actuarial gain Benefits paid Projected benefit obligation at end of year Accumulated benefit obligation at end of year Change in Plan Assets: Fair value of assets at beginning of period Actual loss on assets Benefits paid Fair value of assets at end of year Funded Status: Projected pension benefit obligation Fair value of assets Funded status at end of year Amounts Recognized in Accumulated Other Comprehensive Income Consist of: Net gain 91 Successor Period from October 3, 2016 through December 31, 2016 $ $ $ $ 3.79% 4.89% 3.50% 2 1 (1) 2 (4) (2) 4.31% 3.50% Successor Period from October 3, 2016 through December 31, 2016 $ $ $ $ $ $ $ $ 154 2 1 (12) (1) 144 136 124 (6) (1) 117 (144) 117 (27) 4 The following table provides information regarding pension plans with projected benefit obligation (PBO) and accumulated benefit obligation (ABO) in excess of the fair value of plan assets.

Fixed income securities held primarily consist of corporate bonds from a diversified range of companies, US Treasuries and agency securities and money market instruments. Equity securities are held to enhance returns by participating in a wide range of investment opportunities. International equity securities are used to further diversify the equity portfolio and may include investments in both developed and emerging markets. The target asset allocation ranges of pension plan investments by asset category are as follows: Asset Category: Fixed income US equities International equities Target Allocation Ranges 74% - 86% 8% - 14% 6% - 12% Expected Long-Term Rate of Return on Assets Assumption The Retirement Plan strategic asset allocation is determined in conjunction with the plan's advisors and utilizes a comprehensive Asset-Liability modeling approach to evaluate potential long-term outcomes of various investment strategies. The study incorporates long-term rate of return assumptions for each asset class based on historical and future expected asset class returns, current market conditions, rate of inflation, current prospects for economic growth, and taking into account the diversification benefits of investing in multiple asset classes and potential benefits of employing active investment management.

Significant Concentrations of Risk The plans' investments are exposed to risks such as interest rate, capital market and credit risks. We seek to optimize return on investment consistent with levels of liquidity and investment risk which are prudent and reasonable, given prevailing capital market conditions and other factors specific to us. While we recognize the importance of return, investments will be diversified in order to minimize the risk of large losses unless, under the circumstances, it is clearly prudent not to do so. There are also various restrictions and guidelines in place including limitations on types of investments allowed and portfolio weightings for certain investment securities to assist in the mitigation of the risk of large losses. Assumed Discount Rate We selected the assumed discount rate using the Aon Hewitt AA Above Median yield curve, which is based on corporate bond yields and at December 31, 2016 consisted of 489 corporate bonds with an average rating of AA using Moody's, Standard & Poor's Rating Services and Fitch Ratings, Ltd. ratings. Amortization in 2017 We estimate amortization of the net actuarial gain for the defined benefit pension plan from accumulated other comprehensive income into net periodic benefit cost will be immaterial. We estimate amortization of the net actuarial gain and prior service credit for the OPEB plan from accumulated other comprehensive income into net periodic benefit cost will be immaterial. Contributions No contributions are expected to be made to the pension plan in 2017. OPEB plan funding in the period from October 3, 2016 through December 31, 2016 totaled $1 million, and funding in 2017 is expected to total $5 million. In September 2016, a cash contribution totaling $2 million was made to the EFH Retirement Plan, all of which was contributed by our Predecessor. In December 2015, a cash contribution totaling $67 million was made to the EFH Retirement Plan assets, of which $51 million was contributed by Oncor and $16 million was contributed by our Predecessor. Each of these contributions resulted in the Retirement Plan being fully funded as calculated under the provisions of ERISA. As a result of the Bankruptcy Filing, participants in the EFH Retirement Plan who chose to retire would not be eligible for the lump sum payout option under the EFH Retirement Plan unless the EFH Retirement Plan was fully funded. OPEB plan funding in the period from January 1, 2016 through October 2, 2016 totaled $3 million. Future Benefit Payments Estimated future benefit payments to beneficiaries are as follows: Pension benefits OPEB Thrift Plan 2017 2018 2019 2020 2021 2022-26 $ $ 6 5 $ $ 6 5 $ $ 7 5 $ $ 8 6 $ $ 8 6 $ $ 53 32 Our employees may participate in a qualified savings plan (the Thrift Plan). This plan is a participant-directed defined contribution plan intended to qualify under Section 401(a) of the Code, and is subject to the provisions of ERISA. Under the terms of the Thrift Plan, employees who do not earn more than the IRS threshold compensation limit used to determine highly compensated employees may contribute, through pre-tax salary deferrals and/or after-tax payroll deductions, the lesser of 75% of their regular salary or wages or the maximum amount permitted under applicable law. Employees who earn more than such threshold may contribute from 1% to 20% of their regular salary or wages. Employer matching contributions are also made in an amount equal to 100% (75% for employees covered under the Traditional Retirement Plan Formula) of the first 6% of employee contributions. Employer matching contributions are made in cash and may be allocated by participants to any of the plan's investment options. 96 Employer contributions to the Thrift Plan totaled $5 million, $16 million, $21 million and $21 million for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. 19. STOCK-BASED COMPENSATION Vistra Energy 2016 Omnibus Incentive Plan On the Effective Date, the Vistra Energy board of directors (Board) adopted the 2016 Omnibus Incentive Plan (2016 Incentive Plan), under which an aggregate of 22,500,000 shares of our common stock were reserved for issuance as equity-based awards to our non-employee directors, employees, and certain other persons. The Board or any committee duly authorized by the Board will administer the 2016 Incentive Plan and has broad authority under the 2016 Incentive Plan to, among other things: (a) select participants, (b) determine the types of awards that participants are to receive and the number of shares that are to be subject to such awards and (c) establish the terms and conditions of awards, including the price (if any) to be paid for the shares of the award. The types of awards that may be granted under the 2016 Incentive Plan include stock options, RSUs, restricted stock, performance awards and other forms of awards granted or denominated in shares of Vistra Energy common stock, as well as certain cash-based awards. If any stock option or other stock-based award granted under the 2016 Incentive Plan expires, terminates or is canceled for any reason without having been exercised in full, the number of shares of Vistra Energy common stock underlying any unexercised award shall again be available for the purpose of awards under the 2016 Incentive Plan. If any shares of restricted stock, performance awards or other stock-based awards denominated in shares of Vistra Energy common stock awarded under the 2016 Incentive Plan are forfeited for any reason, the number of forfeited shares shall again be available for purposes of awards under the 2016 Incentive Plan. Any award under the 2016 Incentive Plan settled in cash shall not be counted against the maximum share limitation. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2016 Incentive Plan and any outstanding awards, as well as the exercise or purchase price of awards, and performance targets under certain types of performance-based awards, are required to be adjusted in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the Vistra Energy stockholders. Stock-based compensation expense is reported as SG&A in the statement of consolidated net income (loss) as follows: Total stock-based compensation expense Income tax benefit Stock based-compensation expense, net of tax Successor Period from October 3, 2016 through December 31, 2016 3 $ (1) 2 $ 97 Stock Options The table below summarizes information about stock options granted during the the Successor period from October 3, 2016 through December 31, 2016. The fair value of each stock option is estimated on the date of grant using a Black-Scholes option- pricing model. The risk-free interest rate used in the option valuation model was based on yields available on the grant dates for US Treasury Strips with maturity consistent with the expected life assumption. The expected term of the option represents the period of time that options granted are expected to be outstanding and is based on the SEC Simplified Method (midpoint of average vesting time and contractual term). Expected volatility is based on an average of the historical, daily volatility of a peer group selected by Vistra Energy over a period consistent with the expected life assumption ending on the grant date. We assumed no dividend yield in the valuation of the options. These options may be exercised over a four year graded vesting period and will expire ten years from the grant date. The 2016 Incentive Plan includes an anti-dilutive provision that requires any outstanding option awards to be adjusted for the effect of equity restructurings. In March 2017, the board of directors of Vistra Energy declared that the exercise price of each outstanding option be reduced by $2.32, the amount per share of common stock related to the Special Dividend (see Note 15). Stock options outstanding at December 31, 2016 are all held by current employees. The weighted average assumptions used to value grant options are detailed below: Total outstanding at beginning of period Granted Forfeited or expired Total outstanding at end of period Stock Options (in thousands) Weighted Average Exercise Price — 15.81 15.58 15.81 Weighted Average Remaining Contractual Term (Years) — 9.81 9.81 9.81 7,379 — $ $ (22) $ $ 7,357 Expected to vest 7,357 $ 15.81 9.81 Aggregate Intrinsic Value (in millions) $ $ $ $ $ — — — — — At December 31, 2016, $32 million of unrecognized compensation cost related to unvested stock options granted under the 2016 Incentive Plan are expected to be recognized over a weighted average period of 3.8 years. Restricted Stock Units We granted 2.165 million restricted stock units to employees in the Successor period from October 3, 2016 through December 31, 2016. Total outstanding at beginning of period Granted Forfeited or expired Total outstanding at end of period Restricted Stock Units (in thousands) Weighted Average Grant Date Fair Value — 15.79 15.58 15.79 — $ $ (6) $ $ 2,165 2,159 Weighted Average Remaining Contractual Term (Years) — 2.3 2.3 2.3 Expected to vest 2,159 $ 15.79 2.3 Aggregate Intrinsic Value (in millions) $ $ $ $ $ — 33.6 (0.1) 33.5 33.5 At December 31, 2016, $32 million of unrecognized compensation cost related to unvested restricted stock units granted under the 2016 Incentive Plan are expected to be recognized over a weighted average period of 3.8 years. 98 20. RELATED-PARTY TRANSACTIONS Successor In connection with Emergence, we entered into agreements with certain of our affiliates and with parties who received shares of common stock and TRA Rights in exchange for their claims. Registration Rights Agreement Pursuant to the Plan of Reorganization, on the Effective Date, we entered into a Registration Rights Agreement (the Registration Rights Agreement) with certain selling stockholders providing for registration of the resale of the Vistra Energy common stock held by such selling stockholders. In December 2016, we filed a Form S-1 registration statement with the SEC to register for resale the shares of Vistra Energy common stock held by certain significant stockholders pursuant to the Registration Rights Agreement. The registration statement was amended in February 2017. The registration statement has not yet been declared effective by the SEC. Among other things, under the terms of the Registration Rights Agreement: • we will be required to use reasonable best efforts to convert the Form S-1 registration statement into a registration statement on Form S-3 as soon as reasonably practicable after we become eligible to do so and to have such Form S-3 declared effective as promptly as practicable (but in no event more than 30 days after it is filed with the SEC); • • if we propose to file certain types of registration statements under the Securities Act with respect to an offering of equity securities, we will be required to use our reasonable best efforts to offer the other parties to the Registration Rights Agreement the opportunity to register all or part of their shares on the terms and conditions set forth in the Registration Rights Agreement; and the selling stockholders received the right, subject to certain conditions and exceptions, to request that we file registration statements or amend or supplement registration statements, with the SEC for an underwritten offering of all or part of their respective shares of Vistra Energy common stock (a Demand Registration), and the Company is required to cause any such registration statement or amendment or supplement (a) to be filed with the SEC promptly and, in any event, on or before the date that is 45 days, in the case of a registration statement on Form S-1, or 30 days, in the case of a registration statement on Form S-3, after we receive the written request from the relevant selling stockholders to effectuate the Demand Registration and (b) to become effective as promptly as reasonably practicable and in any event no later than 120 days after it is initially filed. All expenses of registration under the Registration Rights Agreement, including the legal fees of one counsel retained by or on behalf of the selling stockholders, will be paid by us. There were no legal fee expenses paid or accrued by Vistra Energy on behalf of the selling stockholders during the Successor period from October 3, 2016 through December 31, 2016. Tax Receivable Agreement On the Effective Date, Vistra Energy entered into the TRA with a transfer agent on behalf of certain former first lien creditors of TCEH. See Note 10 for discussion of the TRA. Predecessor See Note 2 for a discussion of certain agreements entered into on the Effective Date between EFH Corp. and Vistra Energy with respect to the separation of the entities, including a separation agreement, a transition services agreement, a tax matters agreement and a settlement agreement. 99 The following represent our Predecessor's significant related-party transactions. As of the Effective Date, pursuant to the Plan of Reorganization, the Sponsor Group, EFH Corp., EFIH, Oncor Holdings and Oncor ceased being affiliates of Vistra Energy and its subsidiaries, including the TCEH Debtors and the Contributed EFH Debtors. • Our retail operations (and prior to the Effective Date, our Predecessor) pay Oncor for services it provides, principally the delivery of electricity. Expenses recorded for these services, reported in fuel, purchased power costs and delivery fees, totaled approximately $700 million, $955 million and $971 million for the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. The consolidated balance sheet at December 31, 2015 reflected amounts due currently to Oncor totaling $118 million (included in trade accounts and other payables to affiliates) largely related to these electricity delivery fees. • Contributions to the EFH Corp. retirement plan by both Oncor and TCEH in 2014, 2015 and 2016 resulted in the EFH Corp. retirement plan being fully funded as calculated under the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). In September 2016, a cash contribution totaling $2 million was made to the EFH Corp. retirement plan, all of which was contributed by TCEH, which resulted in the EFH Retirement Plan continuing to be fully funded as calculated under the provisions of ERISA. The balance of the advance totaled $24 million at December 31, 2015, with $6 million recorded as a current asset and $18 million recorded as a noncurrent asset. On the Effective Date, the EFH Retirement Plan was transferred to Vistra Energy pursuant to a separation agreement between Vistra Energy and EFH Corp., and the advance was settled as part of fresh-start reporting. • Receivables from affiliates were measured at historical cost and primarily consisted of notes receivable for cash loaned by our Predecessor to EFH Corp. for debt principal and interest payments and other general corporate purposes of EFH Corp. as discussed above. Our Predecessor reviewed economic conditions, counterparty credit scores and historical payment activity to assess the overall collectability of its affiliated receivables. There were no credit loss allowances at December 31, 2015. • A former subsidiary of EFH Corp. billed our subsidiaries for information technology, financial, accounting and other administrative services at cost. These charges, which are largely settled in cash and primarily reported in SG&A expenses, totaled $157 million, $205 million and $204 million for the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. These amounts included allocated expense, which totaled $10 million for the year ended December 31, 2014, for management fees owed and paid by EFH Corp. to the Sponsor Group. Effective with the Petition Date, EFH Corp. suspended allocations of such fees to TCEH. Fees accrued as of the Petition Date were classified as LSTC and were eliminated in December 2015 as part of the Settlement Agreement. • Under Texas regulatory provisions, the trust fund for decommissioning the Comanche Peak nuclear generation facility is funded by a delivery fee surcharge billed to REPs by Oncor, as collection agent, and remitted monthly to a subsidiary of Vistra Energy (and prior to the Effective Date, our Predecessor) for contribution to the trust fund with the intent that the trust fund assets, reported in investments in the consolidated balance sheets, will ultimately be sufficient to fund the future decommissioning liability, reported in noncurrent liabilities in the consolidated balance sheets. The delivery fee surcharges remitted to our Predecessor totaled $15 million, $17 million and $17 million for the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. Income and expenses associated with the trust fund and the decommissioning liability incurred by a subsidiary of Vistra Energy (and prior to the Effective Date, our Predecessor) are offset by a net change in a receivable/payable that ultimately will be settled through changes in Oncor's delivery fee rates. At December 31, 2015, the excess of the trust fund balance over the decommissioning liability resulted in a payable totaling $409 million and is reported in noncurrent liabilities. • EFH Corp. files consolidated federal income tax and Texas state margin tax returns that included our results prior to the Effective Date; however, under a Federal and State Income Tax Allocation Agreement, our federal income tax and Texas margin tax expense and related balance sheet amounts, including income taxes payable to or receivable from EFH Corp., were recorded as if our Predecessor filed its own corporate income tax return. As of December 31, 2015, our Predecessor had current income tax liabilities due to EFH Corp. of $11 million. Our Predecessor made tax payments to EFH Corp. of $22 million, $29 million and $31 million for the Predecessor period from January 1, 2016 through December 31, 2016 and the years ended December 31, 2015 and 2014, respectively. In 2015, $609 million of income tax liability was eliminated under the terms of the Settlement Agreement. See Note 9 for discussion of cessation of payment of federal income taxes pursuant to the Settlement Agreement. 100 • In 2007, TCEH entered into the TCEH Senior Secured Facilities with syndicates of financial institutions and other lenders. These syndicates included affiliates of GS Capital Partners, which is a member of the Sponsor Group. Affiliates of each member of the Sponsor Group have from time to time engaged in commercial banking transactions with TCEH and/or provided financial advisory services to TCEH, in each case in the normal course of business. • Affiliates of GS Capital Partners were parties to certain commodity and interest rate hedging transactions with our Predecessor in the normal course of business. • Affiliates of the Sponsor Group sold or acquired debt or debt securities issued by our Predecessor in open market transactions or through loan syndications. • As a result of debt repurchase and exchange transactions in 2009 through 2011, EFH Corp. and EFIH held TCEH debt securities at December 31, 2014 as shown below (principal amounts). The $382 million in notes payable as of the Petition Date was classified as LSTC. The amounts of TCEH debt held by EFIH or EFH Corp. were eliminated as a result of the Settlement Agreement approved by the Bankruptcy Court in December 2015 (see Note 2). In conjunction with the Settlement Agreement approved by the Bankruptcy Court in December 2015, EFH Corp. and EFIH waived their rights to the claims associated with these debt securities resulting in a gain recorded in reorganization items (see Note 4). TCEH Senior Notes: Held by EFH Corp. Held by EFIH TCEH Term Loan Facilities: Held by EFH Corp. Total Principal Amount $ $ 284 79 19 382 Interest expense on the notes totaled $1 million and $13 million for the years ended December 31, 2015 and 2014, respectively. Contractual interest, not paid or recorded, totaled $37 million and $25 million for the years ended December 31, 2015 and 2014, respectively. See Note 11. 21. SEGMENT INFORMATION The operations of Vistra Energy are aligned into two reportable business segments: Wholesale Generation and Retail Electricity. Our chief operating decision maker reviews the results of these two segments separately and allocates resources to the respective segments as part of our strategic operations. These two business units offer different products or services and involve different risks. The Wholesale Generation segment is engaged in electricity generation, wholesale energy sales and purchases, commodity risk management activities, fuel production and fuel logistics management, all largely in the ERCOT market. These activities are substantially all conducted by Luminant. The Retail Electricity segment is engaged in retail sales of electricity and related services to residential, commercial and industrial customers, all largely in the ERCOT market. These activities are substantially all conducted by TXU Energy. Corporate and Other represents the remaining non-segment operations consisting primarily of general corporate expenses, interest, taxes and other expenses related to our support functions that provide shared services to our Wholesale Generation and Retail Electricity segments. The accounting policies of the business segments are the same as those described in the summary of significant accounting policies in Note 1. Our chief operating decision maker uses more than one measure to assess segment performance, including reported segment operating income and segment net income (loss), which is the measure most comparable to consolidated net income (loss) prepared based on GAAP. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices or regulated rates. Certain shared services costs are allocated to the segments. 101 Operating revenues (a) Wholesale Generation Retail Electricity Eliminations Consolidated operating revenues Depreciation and amortization Wholesale Generation Retail Electricity Corporate and Other Eliminations Consolidated depreciation and amortization Operating income (loss) Wholesale Generation Retail Electricity Corporate and Other Consolidated operating income (loss) Interest expense and related charges Wholesale Generation Retail Electricity Corporate and Other Eliminations Consolidated interest expense and related charges Income tax benefit (all Corporate and Other) Net income (loss) Wholesale Generation Retail Electricity Corporate and Other Consolidated net income (loss) Capital expenditures Wholesale Generation Retail Electricity Consolidated capital expenditures Successor Period from October 3, 2016 through December 31, 2016 $ $ $ $ $ $ $ $ $ $ $ $ $ 450 912 (171) 1,191 53 153 11 (1) 216 (255) 111 (17) (161) (1) — 66 (5) 60 70 (251) 114 (26) (163) 84 5 89 ____________ (a) Includes third-party unrealized net losses from mark-to-market valuations of commodity positions of $182 million recorded to the Wholesale Generation segment and $6 million recorded to the Retail Electricity segment.

Decommissioning costs are being recovered from Oncor's customers as a delivery fee surcharge over the life of the plant and deposited by Vistra Energy (and prior to the Effective Date, a subsidiary of TCEH) in the trust fund. Income and expense associated with the trust fund and the decommissioning liability are offset by a corresponding change in a receivable/payable (currently a payable reported in noncurrent liabilities) that will ultimately be settled through changes in Oncor's delivery fees rates. The nuclear decommissioning trust fund was not a debtor in the Chapter 11 Cases. A summary of investments in the fund follows: Successor December 31, 2016 Debt securities (b) Equity securities (c) Total Debt securities (b) Equity securities (c) Total $ $ $ $ Cost (a) Unrealized gain 10 $ 368 378 $ 333 309 642 Unrealized loss $ Predecessor December 31, 2015 Cost (a) Unrealized gain 11 $ 315 326 $ 310 291 601 Unrealized loss $ $ $ Fair market value 340 672 1,012 Fair market value 319 599 918 (3) $ (5) (8) $ (2) $ (7) (9) $ ____________ (a) Includes realized gains and losses on securities sold. (b) The investment objective for debt securities is to invest in a diversified tax efficient portfolio with an overall portfolio rating of AA or above as graded by S&P or Aa2 by Moody's Investors Services, Inc. The debt securities are heavily weighted with municipal bonds. The debt securities had an average coupon rate of 3.56% and 3.68% at December 31, 2016 and 2015, respectively, and an average maturity of 9 years and 8 years at December 31, 2016 and 2015, respectively. (c) The investment objective for equity securities is to invest tax efficiently and to match the performance of the S&P 500 Index. Debt securities held at December 31, 2016 mature as follows: $102 million in one to five years, $90 million in five to ten years and $148 million after ten years.

Our property, plant and equipment consists of our power generation assets, related mining assets, information system hardware, capitalized corporate office lease space and other leasehold improvements. At December 31, 2016, the capital lease for the building totaled $64 million with accumulated depreciation of less than $1 million. The estimated remaining useful lives range from 3 to 37 years for our property, plant and equipment. Asset Retirement and Mining Reclamation Obligations (ARO) These liabilities primarily relate to nuclear generation plant decommissioning, land reclamation related to lignite mining, removal of lignite/coal fueled plant ash treatment facilities and generation plant asbestos removal and disposal costs. There is no earnings impact with respect to changes in the nuclear plant decommissioning liability, as all costs are recoverable through the regulatory process as part of delivery fees charged by Oncor. As part of fresh start reporting, new fair values were established for all AROs for the Successor. At December 31, 2016, the current value of our ARO related to our nuclear generation plant decommissioning totaled $1.2 billion, which exceeds the fair value of the assets contained in the nuclear decommissioning trust. Since the costs to ultimately decommission that plant are recoverable through the regulatory rate making process as part of Oncor's delivery fees, a corresponding regulatory asset has been recorded to our consolidated balance sheet of $188 million in other noncurrent assets. 106 The following tables summarize the changes to these obligations, reported in other current liabilities and other noncurrent liabilities and deferred credits in the consolidated balance sheets for the Successor period ended December 31, 2016, and the Predecessor periods ended October 2, 2016 and December 31, 2015: Successor: Fair value of liability established at October 3, 2016 Additions: Accretion — October 3, 2016 through December31, 2016 Reductions: Payments — October 3, 2016 through December31, 2016 Liability at December 31, 2016 Less amounts due currently Noncurrent liability at December 31, 2016 $ Nuclear Plant Decommissioning 1,192 $ Mining Land Reclamation Other Total $ 374 $ 152 $ 1,718 8 — 1,200 — 1,200 $ 5 (4) 375 (53) 322 $ 1 (2) 151 (2) 149 $ 14 (6) 1,726 (55) 1,671 Predecessor: Liability at January 1, 2015 Additions: Accretion Adjustment for new cost estimate (a) Incremental reclamation costs (b) Reductions: Payments Liability at December 31, 2015 (c) Additions: Accretion — January 1, 2016 through October 2, 2016 Adjustment for new cost estimate Incremental reclamation costs Reductions: Payments — January 1, 2016 through October 2, 2016 Liability at October 2, 2016 Less amounts due currently Noncurrent liability at October 2, 2016 $ Nuclear Plant Decommissioning 413 $ Mining Land Reclamation Other Total $ 165 $ 36 $ 25 70 — — 508 22 — — — 530 — 530 20 — 84 (54) 215 16 — 14 6 — 69 (4) 107 5 1 12 (37) 208 (50) 158 $ (3) 122 (1) 121 $ $ 614 51 70 153 (58) 830 43 1 26 (40) 860 (51) 809 ____________ (a) The adjustment for nuclear plant decommissioning resulted from a new cost estimate completed in 2015. Under applicable accounting standards, the liability is remeasured when significant changes in the amount or timing of cash flows occurs, and PUCT rules require a new cost estimate at least every five years.

As described in Note 1 to the Financial Statements, Vistra Energy is considered a new reporting entity for accounting purposes as of the Effective Date, and its financial statements reflect the application of fresh start reporting. The financial statements of Vistra Energy (the Successor) for periods subsequent to the Effective Date are not comparable to the financial statements of TCEH (the Predecessor) for periods prior to the Effective Date, as those previous periods do not give effect to any adjustments to the carrying values of assets or amounts of liabilities that resulted from the Plan of Reorganization, and the related application of fresh start reporting, which includes accounting policies implemented by Vistra Energy that may differ from the Predecessor. See Note 3 to the Financial Statements for further discussion regarding fresh start reporting. The following discussion and analysis of our financial condition and results of operations for the Successor period from October 3, 2016 through December 31, 2016 and the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014 should be read in conjunction with the consolidated financial statements and the notes to those statements. Results are impacted by the effects of fresh start reporting, the Bankruptcy Filing and the application of Financial Accounting Standards Board Accounting Standards Codification (ASC) 852, Reorganizations. All dollar amounts in the tables in the following discussion and analysis are stated in millions of US dollars unless otherwise indicated. Business Vistra Energy is a holding company operating an integrated power business in Texas. Through our Luminant and TXU Energy subsidiaries, we are engaged in competitive electricity market activities including power generation, wholesale energy sales and purchases, commodity risk management and retail sales of electricity and related services to end users. Prior to the Effective Date, TCEH was a holding company for subsidiaries principally engaged in the same activities as Vistra Energy. Operating Segments Subsequent to the Effective Date, Vistra Energy has two reportable segments: the Wholesale Generation segment, consisting largely of Luminant, and the Retail Electricity segment, consisting largely of TXU Energy. Prior to the Effective Date, there were no reportable business segments for TCEH. See Note 21 to the Financial Statements for further information concerning reportable business segments. Significant Activities and Events and Items Influencing Future Performance Chapter 11 Cases and Emergence — On April 29, 2014 (the Petition Date), EFH Corp. and the substantial majority of its direct and indirect subsidiaries, including EFIH, EFCH and TCEH but excluding the Oncor Ring-Fenced Entities (collectively, the Debtors), 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). On October 3, 2016 (the Effective Date), subsidiaries of TCEH that were Debtors in the Chapter 11 Cases (the TCEH Debtors) and certain EFH Corp. subsidiaries (the Contributed EFH Debtors) completed their reorganization under the Bankruptcy Code and emerged from the Chapter 11 Cases as subsidiaries of a newly-formed company, Vistra Energy (Emergence). On the Effective Date, Vistra Energy was spun-off from EFH Corp. in a tax-free transaction to the former first lien creditors of TCEH (Spin-Off). As a result, as of the Effective Date, Vistra Energy is a holding company for subsidiaries principally engaged in competitive electricity market activities including power generation, wholesale energy sales and purchases, commodity risk management and retail sales of electricity and related services to end users. See Note 2 to the Financial Statements for further discussion regarding the Chapter 11 Cases and Emergence. 113 Support Cost Reductions — In October 2016, we began executing a plan to reduce support costs across our business by focusing on organizational structures of support functions and reducing costs associated with third-party service providers. As part of that plan, we reduced our workforce by approximately 500 people to better align our cost structure to current market conditions. These market conditions include persistently low wholesale power prices, environmental regulatory pressure and a highly competitive retail market. As part of these reductions, we incurred severance costs of approximately $43 million, which were primarily recorded to selling, general and administrative expenses and operating costs during the period. Additionally, in October 2016 we began renegotiating and amending certain service contracts with providers to further reduce our support costs. Lamar and Forney Acquisition — In April 2016, Luminant purchased all of the membership equity interests in La Frontera Holdings, LLC, the indirect owner of two natural gas fueled generation facilities representing nearly 3,000 MW of capacity located in ERCOT, from a subsidiary of NextEra Energy, Inc. The facility in Forney, Texas has a capacity of 1,912 MW and the facility in Paris, Texas has a capacity of 1,076 MW. The aggregate purchase price was approximately $1.313 billion, which included the repayment of approximately $950 million of existing project financing indebtedness, plus approximately $236 million for cash and net working capital subject to final settlement. The purchase price was funded by cash-on-hand and additional borrowings under the Predecessor's DIP Facility totaling $1.1 billion. After completing the acquisition, the Predecessor repaid approximately $230 million of borrowings under the Predecessor's DIP Facility primarily utilizing cash acquired in the transaction. See Note 6 to the Financial Statements for further discussion of the acquisition. Conversion of TCEH DIP Roll Facilities to Vistra Operations Credit Facilities — In August 2016, our Predecessor entered into the TCEH DIP Roll Facilities. Prior to the Effective Date, the TCEH DIP Roll Facilities provided for up to $4.250 billion in senior secured, super-priority financing consisting of a revolving credit facility of up to $750 million, a term loan letter of credit facility of up to $650 million and a term loan facility of up to $2.850 billion. Prior to the Effective Date, approximately $3.5 billion was outstanding under the Predecessor's TCEH DIP Roll Facilities, approximately $2.65 billion of which was used to repay all amounts outstanding under the Predecessor's DIP Facility, and the balance of which was used for general business purposes. Upon the Effective Date, the TCEH DIP Roll Facilities were converted into the Vistra Operations Credit Facilities with maturity dates of August 2021 for the revolving credit facility and August 2023 for the term loan facilities. The Vistra Operations Credit Facilities initially consisted of up to $4.250 billion in senior secured, first lien financing consisting of a revolving credit facility of up to $750 million, a term loan facility of up to $2.850 billion and a term loan letter of credit facility of up to $650 million. In December 2016, we incurred approximately $1 billion of incremental term loans with a maturity date of December 2023 and $110 million of incremental revolving credit commitments under the Vistra Operations Credit Facility. Proceeds from the incremental term loan facility were used to fund the Special Dividend (see Note 15 to the Financial Statements) in the aggregate amount of approximately $1 billion that was approved by Vistra Energy's board of directors and paid in December 2016. As of December 31, 2016, approximately $4.5 billion was outstanding under the Vistra Operations Credit Facilities. In February 2017, certain pricing terms for the Vistra Operations Credit Facility were amended. Any amounts borrowed under the Revolving Credit Facility will bear interest based on applicable LIBOR rates plus 2.75%. Amounts borrowed under the Initial Term Loan B Facility and the Term Loan C Facility will bear interest based on applicable LIBOR rates, subject to a 0.75% floor, plus 2.75%. See Note 13 to the Financial Statements for details of the Vistra Operations Credit Facilities, the DIP Roll Facilities and the DIP Facility. Environmental Matters — See Note 14 to Financial Statements for a discussion of greenhouse gas emissions, the CSAPR, regional haze, state implementation plan and other recent EPA actions as well as related litigation. 114 Key Risks and Challenges Following is a discussion of key risks and challenges facing management and the initiatives currently underway to manage such challenges. These matters involve risks that could have a material effect on our results of operations, liquidity or financial condition. Natural Gas Price and Market Heat Rate Exposure The price of power in the ERCOT market is typically set by natural gas-fueled generation facilities, with wholesale prices generally tracking increases or decreases in the price of natural gas. In recent years, natural gas supply has outpaced demand primarily as a result of development and expansion of hydraulic fracturing in natural gas extraction; the supply/demand imbalance has resulted in historically low natural gas prices, and such prices have historically been volatile. The table below shows the general decline in forward natural gas prices over the last several years (amounts are per MMBtu.) ________________ (a) Settled prices represent the average of NYMEX Henry Hub monthly settled prices of financial contracts for the year ending on the date presented. Forward prices represent the three-year average of NYMEX Henry Hub monthly forward prices at the date presented. Three year forward prices are presented as such period is generally deemed to be a liquid period. 115 In contrast to our natural gas fueled generation facilities, changes in natural gas prices have no significant effect on the cost of generating power at our nuclear-, lignite- and coal-fueled facilities, which represent the substantial majority of our generation capacity. Consequently, all other factors being equal, these nuclear-, lignite- and coal-fueled generation assets increase or decrease in value as natural gas prices and market heat rates rise or fall, respectively, because of the effect on our operating margins from changes in wholesale electricity prices in ERCOT. A persistent decline in the price of natural gas, and the corresponding decline in the price of power in the ERCOT market, would likely have a material adverse effect on our results of operations, liquidity and financial condition, predominantly related to the production of power generation volumes in excess of the volumes utilized to service our retail customer load requirements. The wholesale market price of electricity divided by the market price of natural gas represents the market heat rate. Market heat rate can be affected by a number of factors, including generation availability, mix of assets and the efficiency of the marginal supplier (generally natural gas-fueled generation facilities) in generating electricity. Our market heat rate exposure is impacted by changes in the availability of generation resources, such as additions and retirements of generation facilities, and mix of generation assets in ERCOT. For example, increasing renewable (wind and solar) generation capacity generally depresses market heat rates. Our heat rate exposure is also impacted by the potential economic backdown of our generation assets. Decreases in market heat rates decrease the value of our generation assets because lower market heat rates generally result in lower wholesale electricity prices, and vice versa. However, even though market heat rates have generally increased over the past several years, wholesale electricity prices have declined due to the greater effect of falling natural gas prices. As a result of our exposure to the variability of natural gas prices and market heat rates in ERCOT, retail sales and hedging activities are critical to our operating results and maintaining consistent cash flow levels. Our integrated power generation and retail electricity business provides us opportunities to hedge our generation position utilizing retail electricity markets as a sales channel. In addition, our approach to managing electricity price risk focuses on the following: • • • employing disciplined, liquidity-efficient hedging and risk management strategies through physical and financial energy- related contracts intended to partially hedge gross margins; continuing focus on cost management to better withstand gross margin volatility; following a retail pricing strategy that appropriately reflects the value of our product offering to customers, the magnitude and costs of commodity price, liquidity risk and retail demand variability, and • improving retail customer service to attract and retain high-value customers. We have engaged in natural gas hedging activities to mitigate the risk of lower wholesale electricity prices that have corresponded to declines in natural gas prices. While current and forward natural gas prices are currently depressed, we continue to seek opportunities to manage our wholesale power price exposure through hedging activities, including forward wholesale and retail electricity sales. Taking together forward wholesale, retail electricity sales and other retail customer considerations and all other hedging positions, at March 1, 2017, we had effectively hedged an estimated 92% and 52% of the natural gas price exposure related to our overall business for 2017 and 2018, respectively. Additionally, taking into consideration our overall heat rate exposure and related hedging positions at March 1, 2017, we had effectively hedged 85% and 35% of the heat rate exposure to our overall business for 2017 and 2018, respectively. 116 The following sensitivity table provides approximate estimates of the potential impact of movements in natural gas prices and market heat rates on realized pretax earnings (in millions) on the hedge positions noted in the paragraph above for the periods presented. The estimates related to price sensitivity are based on our expected generation and retail positions, related hedges and forward prices as of March 1, 2017. $0.50/MMBtu increase in natural gas price (b)(c) $0.50/MMBtu decrease in natural gas price (b)(c) 1.0/MMBtu/MWh increase in market heat rate (d) 1.0/MMBtu/MWh decrease in market heat rate (d) Balance 2017 (a) $ ~40 $ ~(5) $ ~40 $ ~(15) 2018 $ ~190 $ ~(160) $ ~190 $ ~(150) ___________ (a) Balance of 2017 is from March 1, 2017 through December 31, 2017. (b) Assumes conversion of generation positions based on market heat rates and an estimate of natural gas generally being on the margin 70% to 90% of the time in the ERCOT market. (c) Based on Houston Ship Channel natural gas prices at March 1, 2017. (d) Based on ERCOT North Hub around-the-clock heat rates at March 1, 2017. Competitive Retail Markets and Customer Retention Competitive retail activity in ERCOT has resulted in retail customer churn as customers switch retail electricity providers for various reasons. Based on numbers of meters, our total retail customer counts declined approximately 1% in 2016, less than 1% in 2015 and 1% in 2014. Based upon 2016 results discussed below in Results of Operations, a 1% decline in residential customers would result in a decline in annual revenues of approximately $27 million. In responding to the competitive landscape in the ERCOT market, we have attempted to reduce overall customer losses by focusing on the following key initiatives: • Maintaining competitive pricing initiatives on residential service plans; • Actively competing for new customers in areas open to competition within ERCOT, while continuing to strive to enhance the experience of our existing customers; we are focused on continuing to implement initiatives that deliver world-class customer service and improve the overall customer experience; • Establishing and leveraging our TXU EnergyTM brand in the sale of electricity to residential and commercial customers, as the most innovative retailer in the ERCOT market by continuing to develop tailored product offerings to meet customer needs, and • Focusing market initiatives largely on programs targeted at retaining the existing highest-value customers and to recapturing customers who have switched REPs, including maintaining and continuously refining a disciplined contracting and pricing approach and economic segmentation of the business market to enhance targeted sales and marketing efforts and to more effectively deploy our direct-sales force; tactical programs we have initiated include improved customer service, aided by an enhanced customer management system, new product price/service offerings and a multichannel approach for the small business market. Exposures Related to Nuclear Asset Outages Our nuclear assets are comprised of two generation units at the Comanche Peak facility, each with an installed nameplate generation capacity of 1,150 MW. As of December 31, 2016, these units represented approximately 14% of our total generation capacity. The nuclear generation units represent our lowest marginal cost source of electricity. Assuming both nuclear generation units experienced an outage at the same time, the unfavorable impact to pretax earnings is estimated (based upon forward electricity market prices for 2017 at December 31, 2016) to be approximately $1 million per day before consideration of any costs to repair the cause of such outages or receipt of any insurance proceeds. Also see discussion of nuclear facilities insurance in Note 14 to the Financial Statements. 117 The inherent complexities and related regulations associated with operating nuclear generation facilities result in environmental, regulatory and financial risks. The operation of nuclear generation facilities is subject to continuing review and regulation by the NRC, including potential regulation as a result of the NRC's ongoing analysis and response to the effects of the natural disaster on nuclear generation facilities in Fukushima, Japan in 2010, covering, among other things, operations, maintenance, emergency planning, security, and environmental and safety protection. The NRC may implement changes in regulations that result in increased capital or operating costs and may require extended outages, modify, suspend or revoke operating licenses and impose fines for failure to comply with its existing regulations and the provisions of the Atomic Energy Act. In addition, an unplanned outage at another nuclear generation facility could result in the NRC taking action to shut down our Comanche Peak units as a precautionary measure. We participate in industry groups and with regulators to keep current on the latest developments in nuclear safety, operation and maintenance and on emerging threats and mitigating techniques. These groups include, but are not limited to, the NRC, the Institute of Nuclear Power Operations (INPO) and the Nuclear Energy Institute (NEI). We also apply the knowledge gained through our continuing investment in technology, processes and services to improve our operations and to detect, mitigate and protect our nuclear generation assets. The Comanche Peak plant has not experienced an extended unplanned outage, and management continues to focus on the safe, reliable and efficient operations at the facility. Cyber Security and Infrastructure Protection Risk A breach of cyber/data security measures that impairs our information technology infrastructure could disrupt normal business operations and affect our ability to control our generation assets, access retail customer information and limit communication with third parties. Any loss of confidential or proprietary data through a breach could materially affect our reputation, including our TXU EnergyTM brand, expose the company to legal claims or impair our ability to execute on business strategies. We participate in industry groups and with regulators to remain current on emerging threats and mitigating techniques. These groups include, but are not limited to, the US Cyber Emergency Response Team, the National Electric Sector Cyber Security Organization, the NRC and NERC. While the company has not experienced a cyber event causing any material operational, reputational or financial impact, we recognize the growing threat within the general market place and our industry, and are proactively making strategic investments in our perimeter and internal defenses, cyber security operations center and regulatory compliance activities. We also apply the knowledge gained through industry and government organizations to continuously improve our technology, processes and services to detect, mitigate and protect our cyber assets. 118 Application of Critical Accounting Policies Our significant accounting policies are discussed in Note 1 to the Financial Statements. We follow accounting principles generally accepted in the US. Application of these accounting policies in the preparation of our consolidated financial statements requires management to make estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and revenues and expenses during the periods covered. The following is a summary of certain critical accounting policies that are impacted by judgments and uncertainties and under which different amounts might be reported using different assumptions or estimation methodologies. Accounting in Reorganization and Fresh-Start Reporting The consolidated financial statements of our Predecessor reflect the application of ASC 852. During the Chapter 11 Cases, the Debtors, including our Predecessor and its subsidiaries, operated their businesses as debtors-in-possession under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code. ASC 852 applies to entities that have filed a petition for bankruptcy under Chapter 11 of the Bankruptcy Code. The guidance requires that transactions and events directly associated with the reorganization be distinguished from the ongoing operations of the business. In addition, the guidance provides for changes in the accounting and presentation of liabilities. Expenses and income directly associated with the Chapter 11 Cases are reported separately in the statements of consolidated income (loss) as reorganization items. Reorganization items also include adjustments to reflect the carrying value of liabilities subject to compromise (LSTC) at their estimated allowed claim amounts, as such adjustments are determined. See Notes 4 and 5 to the Financial Statements. As of the Effective Date, Vistra Energy applied fresh-start reporting under the applicable provisions of ASC 852. Fresh- start reporting includes (1) distinguishing the consolidated financial statements of the entity that was previously in restructuring from the consolidated financial statements of the entity that emerges from restructuring, (2) assigning the reorganized value of the successor entity by measuring all assets and liabilities of the successor entity at fair value, and (3) selecting accounting policies for the successor entity. The effects from emerging from bankruptcy, including the extinguishment of liabilities, as well as the fresh start reporting adjustments are reported in the Predecessor's statement of consolidated income (loss). The consolidated financial statements of Vistra Energy for periods subsequent to the Effective Date are not comparable to the financial statements of our Predecessor for periods prior to the Effective Date, as those previous periods do not give effect to any adjustments to the carrying values of assets or amounts of liabilities, nor any differences in accounting policies that were a consequence of the Plan of Reorganization or the related application of fresh-start reporting. See Note 3 to the Financial Statements. Derivative Instruments and Mark-to-Market Accounting We enter into contracts for the purchase and sale of energy-related commodities, and also enter into other derivative instruments such as options, swaps, futures and forwards primarily to manage commodity price and interest rate risks. Under accounting standards related to derivative instruments and hedging activities, these instruments are subject to mark-to-market accounting, and the determination of market values for these instruments is based on numerous assumptions and estimation techniques. Mark-to-market accounting recognizes changes in the fair value of derivative instruments in the financial statements as market prices change. Such changes in fair value are accounted for as unrealized mark-to-market gains and losses in net income with an offset to derivative assets and liabilities. The availability of quoted market prices in energy markets is dependent on the type of commodity (e.g., natural gas, electricity, etc.), time period specified and delivery point. In computing fair value for derivatives, each forward pricing curve is separated into liquid and illiquid periods. The liquid period varies by delivery point and commodity. Generally, the liquid period is supported by exchange markets, broker quotes and frequent trading activity. For illiquid periods, fair value is estimated based on forward price curves developed using modeling techniques that take into account available market information and other inputs that might not be readily observable in the market. We estimate fair value as described in Note 16 to the Financial Statements. Accounting standards related to derivative instruments and hedging activities allow for normal purchase or sale elections and hedge accounting designations, which generally eliminate or defer the requirement for mark-to-market recognition in net income and thus reduce the volatility of net income that can result from fluctuations in fair values. Normal purchases and sales are contracts that provide for physical delivery of quantities expected to be used or sold over a reasonable period in the normal course of business and are not subject to mark-to-market accounting if the election as normal is made. 119 We report derivative assets and liabilities in the consolidated balance sheets without taking into consideration netting arrangements that we have with counterparties. Margin deposits that contractually offset these assets and liabilities are reported separately in the consolidated balance sheets. See Note 17 to the Financial Statements for further discussion regarding derivative instruments. Accounting for Income Taxes EFH Corp. files a United States federal income tax return that includes the results of EFCH, EFIH, Oncor Holdings and, prior to the Effective Date, TCEH. EFH Corp. is the corporate parent of the EFH Corp. consolidated group, while each of EFIH, Oncor Holdings, EFCH and, prior to the effective date, TCEH were classified as a disregarded entity for United States federal income tax purposes. Pursuant to applicable United States Treasury regulations and published guidance of the IRS, corporations that are members of a consolidated group have joint and several liability for the taxes of such group. Subsequent to the Effective Date, the TCEH Debtor and the Contributed EFH Debtors are no longer be included in the EFH Corp. consolidated group and are included in a consolidated group of which Vistra Energy is the corporate parent. Prior to the Effective Date, EFH Corp. and certain of its subsidiaries (including EFCH, EFIH, and TCEH, but not including Oncor Holdings and Oncor) were parties to a Federal and State Income Tax Allocation Agreement, which provided, among other things, that any corporate member or disregarded entity in the EFH Corp. group is required to make payments to EFH Corp. in an amount calculated to approximate the amount of tax liability such entity would have owed if it filed a separate corporate tax return. Pursuant to the Plan of Reorganization, the TCEH Debtors and Contributed EFH Debtors rejected this agreement on the Effective Date. See Notes 2 and 10 to the Financial Statements for a discussion of the Tax Matters Agreement that was entered on the Effective Date between EFH Corp. and Vistra Energy. Additionally, since the date of the Settlement Agreement, no further cash payments among the Debtors were made in respect of federal income taxes. EFH Corp. has elected to continue to allocate federal income taxes among the entities that are parties to the Federal and State Income Tax Allocation Agreement. The Settlement Agreement did not alter the allocation and payment for state income taxes, which continued to be settled prior to the Effective Date. Our income tax expense and related consolidated balance sheet amounts involve significant management estimates and judgments. Amounts of deferred income tax assets and liabilities, as well as current and noncurrent accruals, involve estimates and judgments of the timing and probability of recognition of income and deductions by taxing authorities. In assessing the likelihood of realization of deferred tax assets, management considers estimates of the amount and character of future taxable income. Actual income taxes could vary from estimated amounts due to the future impacts of various items, including changes in income tax laws, our forecasted financial condition and results of operations in future periods, as well as final review of filed tax returns by taxing authorities. Income tax returns are regularly subject to examination by applicable tax authorities. In management's opinion, the liability recorded pursuant to income tax accounting guidance related to uncertain tax positions reflects future taxes that may be owed as a result of any examination. See Notes 1 and 9 to the Financial Statements for discussion of income tax matters. Accounting for Tax Receivable Agreement On the Effective Date, we entered into a tax receivable agreement (the TRA) with American Stock Transfer & Trust Company, LLC, as the transfer agent. Pursuant to the TRA, we issued beneficial interests in the rights to receive payments under the TRA (the TRA Rights) to the first lien creditors of our Predecessor to be held in escrow for the benefit of the first lien creditors of our Predecessor entitled to receive such TRA Rights under the Plan. As part of Emergence, Vistra Energy reflected the obligation associated with TRA Rights at fair value in the amount of $574 million related to these future payment obligations. This estimate of fair value is the discounted amount of estimated payments to be made each year under the TRA, based on certain assumptions, including but not limited to: • • the amount of tax basis step-up resulting from the PrefCo Preferred Stock Sale (which is estimated to be approximately $5.5 billion) and the allocation of such tax basis step-up among the assets subject thereto; the depreciable lives of the assets subject to such tax basis step-up, which generally is expected to be 15 years for most of such assets; • a federal corporate income tax rate in all future years of 35%; 120 • the Company generally expects to generate sufficient taxable income to be able to utilize the deductions arising out of (i) the tax basis step up attributable to the PrefCo Preferred Stock Sale, (ii) the entire tax basis of the assets acquired as a result of the Lamar and Forney Acquisition, and (iii) tax benefits related to imputed interest deemed to be paid by us as a result of payments under the TRA in the tax year in which such deductions arise; and • a discount rate of 15%, which represents our view of the rate that a market participant would use based on the risk associated with the uncertainty in the amount and timing of the cash flows. We expect to recognize accretion expense over the life of the TRA Rights liability as the present value of the initially established liability is accreted up over the life of the liability. This noncash accretion expense is reported in the statements of consolidated income (loss) as Impacts of Tax Receivable Agreement. Further, there may be significant changes, which may be material, to the estimate of the related liability due to various reasons including changes in corporate tax law, changes in estimates of future taxable income of Vistra Energy and its subsidiaries and other items. We expect that changes in those estimates will be recognized as adjustments to the related TRA Rights liability, with offsetting impacts recorded in the statements of consolidated income (loss) as Impacts of Tax Receivable Agreement. Impairment of Goodwill and Other Long-Lived Assets We evaluate long-lived assets (including intangible assets with finite lives) for impairment, in accordance with accounting standards related to impairment or disposal of long-lived assets, whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. For our generation assets, possible indications include an expectation of continuing long-term declines in natural gas prices and/or market heat rates or an expectation that "more likely than not" a generation asset will be sold or otherwise disposed of significantly before the end of its estimated useful life. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows related to an asset or group of assets. Further, the unique nature of our property, plant and equipment, which includes a fleet of generation assets with a diverse fuel mix and individual generation units that have varying production or output rates, requires the use of significant judgments in determining the existence of impairment indications and the grouping of assets for impairment testing. We generally utilize an income approach measurement to derive fair values for our long-lived generation assets. The income approach involves estimates of future performance that reflect assumptions regarding, among other things, forward natural gas and electricity prices, market heat rates, the effects of environmental rules, generation plant performance, forecasted capital expenditures and forecasted fuel prices. Any significant change to one or more of these factors can have a material impact on the fair value measurement of our long-lived assets. As a result of the decrease in forecasted wholesale electricity prices, potential effects from environmental regulations and changes to our Predecessor's operating plans in 2015 and 2014, our Predecessor evaluated the recoverability of its generation assets. See Note 8 to the Financial Statements for a discussion of the impairment charges related to certain of those assets. Additional material impairments related to these or other of our generation facilities may occur in the future if forward wholesale electricity prices in ERCOT continue to decline or if additional environmental regulations increase the cost of producing electricity at our generation facilities. Goodwill and intangible assets with indefinite useful lives, such as the intangible asset related to the TXU EnergyTM brand, are required to be tested for impairment at least annually (as of the Effective Date, we have selected October 1 as our annual test date) or whenever events or changes in circumstances indicate an impairment may exist, such as the indicators used to evaluate impairments to long-lived assets discussed above or declines in values of comparable public companies in our industry. Accounting guidance requires goodwill to be allocated to our reporting units, and at December 31, 2016 all goodwill was allocated to our Retail Electricity segment. Goodwill impairment testing is performed at the reporting unit level. Under this goodwill impairment analysis, if at the assessment date, a reporting unit's carrying value exceeds its estimated fair value (enterprise value), the estimated enterprise value of the reporting unit is compared to the estimated fair values of the reporting unit's assets (including identifiable intangible assets) and liabilities at the assessment date, and the resultant implied goodwill amount is then compared to the recorded goodwill amount. Any excess of the recorded goodwill amount over the implied goodwill amount is written off as an impairment charge. 121 The determination of enterprise value involves a number of assumptions and estimates. We use a combination of fair value measurements to estimate enterprise values of our reporting units including: internal discounted cash flow analyses (income approach), and comparable publicly traded company values (market approach). The income approach involves estimates of future performance that reflect assumptions regarding, among other things, forward natural gas and electricity prices, market heat rates, the effects of environmental rules, generation plant performance, forecasted capital expenditures and retail sales volume trends, as well as determination of a terminal value. Another key variable in the income approach is the discount rate, or weighted average cost of capital, applied to the forecasted cash flows. The determination of the discount rate takes into consideration the capital structure, credit ratings and current debt yields of comparable publicly traded companies as well as an estimate of return on equity that reflects historical market returns and current market volatility for the industry. The market approach involves using trading multiples of EBITDA of those selected publicly traded companies to derive appropriate multiples to apply to the EBITDA of our reporting units. Critical judgments include the selection of publicly traded comparable companies and the weighting of the value metrics in developing the best estimate of enterprise value. See Note 7 to the Financial Statements for additional discussion of the Predecessor's goodwill impairment charges. 122 Results of Operations Vistra Energy Consolidated Financial Results — Period from October 3, 2016 through December 31, 2016 Operating revenues Fuel, purchased power costs and delivery fees Operating costs Depreciation and amortization Selling, general and administrative expenses Operating income (loss) Other income Interest expense and related charges Impacts of Tax Receivables Agreement Income (loss) before income taxes Income tax benefit (expense) Net income (loss) Successor Period from October 3, 2016 through December 31, 2016 Wholesale Generation Retail Electricity Eliminations / Corporate and Other Vistra Energy Consolidated $ $ 450 (376) (205) (53) (71) (255) 3 1 — (251) 912 (515) (3) (153) (130) 111 3 — — 114 $ $ (171) $ 171 — (10) (7) (17) 4 (61) (22) (96) 70 (26) $ 1,191 (720) (208) (216) (208) (161) 10 (60) (22) (233) 70 (163) Consolidated operating loss totaled $161 million for the period from October 3, 2016 through December 31, 2016. Results were driven by: • Our Wholesale Generation segment had an operating loss of approximately $255 million for the period which was primarily driven by unrealized mark-to-market losses totaling approximately $273 million for the period (including $113 million of unrealized losses on positions with the Retail Electricity segment). The unrealized losses were driven by increases in forward natural gas prices during the period. Please see the discussion of Wholesale Generation below for further details. • Our Retail Electricity segment had operating income of $111 million for the period which was the result of favorable profit margins, including $113 million of unrealized gains in purchased power costs on positions with the Wholesale Generation segment. Please see the discussion of Retail Electricity below for further details. • Net operating expense related to Eliminations and Corporate and Other activities totaled $17 million and primarily reflected $7 million in amortization of intangible assets and $4 million in post-Emergence restructuring fees. Interest expense and related charges totaled $60 million and reflected $47 million of interest expense incurred on the Vistra Operations Credit Facilities and $11 million of unrealized mark-to-market net losses on interest rate swaps.

Results also reflected the effect of declining average electricity prices on operating revenues, $977 million in adequate protection interest expense paid/accrued on pre-petition debt and $116 million in reorganization items associated with the Chapter 11 Cases. Operating revenues totaled $3.973 billion. Retail electricity revenues totaling $3.154 billion were negatively impacted by declining average prices and reduced electricity usage reflecting milder than normal weather in 2016. Wholesale revenues totaling $649 million were positively impacted by increases in generation volumes (approximately 8,048 GWh) driven by the Lamar and Forney Acquisition in April 2016 (see Note 6 to the Financial Statements), partially offset by lower average wholesale electricity prices. Following is an analysis of amounts reported as net gain from commodity hedging and trading activities. Results are primarily related to natural gas and power hedging activity. Realized net gains Unrealized net gains (losses) Total Predecessor Period From January 1, 2016 through October 2, 2016 $ $ 320 (38) 282 The negative impacts of declining average prices on operating revenues were partially offset by realized net gains reflecting settled gains on derivatives due to declining market prices. These gains were primarily related to natural gas positions. Net unrealized gains (losses) were primarily impacted by reversals of previously recorded unrealized net gains on settled positions. Fuel, purchased power costs and delivery fees totaled $2.082 billion and reflected the impact of declining electricity prices on purchased power costs, partially offset by incremental natural gas fuel costs associated with the Lamar and Forney Acquisition (see Note 6 to the Financial Statements). Operating costs totaled $664 million and primarily reflect maintenance expense for our generation assets, including nuclear maintenance costs due to a spring nuclear refueling outage and incremental operation and maintenance costs associated with the Lamar and Forney Acquisition. Depreciation and amortization expenses totaled $459 million and reflected the effect of noncash impairments of certain long-lived assets recorded in 2015, partially offset by incremental depreciation expense associated with the Lamar and Forney Acquisition. SG&A expenses totaled $482 million and reflected administrative and general salaries, employee benefits, marketing costs related to retail electricity activity and other administrative costs. Results for the period also include $32 million of severance expense, primarily reported in fuel, purchased power and delivery fees and operating costs, associated with certain actions taken to reduce costs related to mining and lignite/coal generation operations. Interest expense and related charges totaled $1.049 billion and reflected $977 million in adequate protection payments approved by the Bankruptcy Court for the benefit of TCEH secured creditors and $76 million in interest expense on debtor-in- possession financing. Income tax benefit totaled $1.267 billion. See Note 9 to the Financial Statements for reconciliation of this effective rate to the US federal statutory rate. 128 Predecessor Financial Results — Year Ended December 31, 2015 Compared to Year Ended December 31, 2014 Loss before income taxes decreased $2.993 billion in 2015 from 2014 to a loss of $5.556 billion. The decrease primarily reflected the larger noncash impairment charges of certain long-lived assets in 2014 and the decrease in interest expense, the decrease in depreciation and amortization expense and a decrease in reorganization items expense in 2015. Operating revenues decreased $608 million in 2015 from 2014, as a result of a decrease in wholesale electricity revenues, partially offset by an increase in retail electricity revenues. Wholesale electricity revenues decreased $587 million in 2015 from 2014 reflecting a $362 million decrease in sales volumes and a $225 million decrease due to lower average wholesale electricity prices. The decrease in wholesale electricity sales volumes was driven by lower generation volumes from increased economic backdown (including seasonal operations) at our lignite and coal generation facilities, which was driven by a 35% decline in average wholesale electricity prices, driven by lower natural gas prices. Retail electricity revenues increased $36 million in 2015 from 2014 primarily reflecting a $310 million increase due to sales volumes driven by an increase in business sales volumes, partially offset by a $274 million decrease due to lower average prices primarily for business markets customers. Fuel, purchased power costs and delivery fees decreased $150 million in 2015 from 2014. Fuel for lignite and coal facilities decreased $48 million in 2015 from 2014 due to a 14% decrease in generation volumes, partially offset by higher lignite mining costs and more western coal in the fuel blend. Fuel for natural gas facilities and purchased power costs decreased $64 million in 2015 from 2014 driven by a 28% decrease in purchased power volumes, lower natural gas prices and a 13% decrease in generation volumes from natural gas generation units. Other costs decreased $101 million in 2015 from 2014, reflecting a $49 million decrease in natural gas purchases for resale and $34 million decrease in amortization of favorable purchase contracts due to impairments recorded at the end of 2014. Delivery fees increased $64 million in 2015 from 2014, primarily reflecting higher retail volumes. Following is an analysis of amounts reported as net gain from commodity hedging and trading activities. The results are primarily related to natural gas and power hedging activity. Realized net gains Unrealized net gains (losses) Total Predecessor Year Ended December 31, 2015 2014 Change $ $ 217 117 334 $ $ 387 (376) 11 $ $ (170) 493 323 Realized net gains on hedging and trading positions decreased $170 million, or 43.9%, in 2015 from 2014, reflecting lower gains due to the 2014 termination of our favorable long-term natural gas hedging program, partially offset by other realized gains from declining market prices in 2015. The $493 million favorable change in unrealized net gains in 2015 from 2014 primarily reflected the 2014 reversal of previously recorded unrealized gains related to the favorable pricing of our long-term natural gas hedging program that terminated in 2014 along with favorable unrealized gains in 2015 due to the impact of declining natural gas prices on our hedging positions. Operating costs decreased $80 million in 2015 from 2014, driven by $55 million in lower nuclear maintenance costs, reflecting a spring refueling in 2014 that was absent in 2015, as well as lower lignite and coal facilities operating costs reflecting lower generation. Depreciation and amortization expenses decreased $418 million in 2015 from 2014, primarily reflecting reduced depreciation expense resulting from the effect of noncash impairments of certain long-lived assets recorded at the end of 2014 and during 2015. Interest expense and related charges decreased $460 million in 2015. The decrease reflected: • • $874 million in lower interest expense on pre-petition debt due to the discontinuance of interest due to the Chapter 11 Cases, and $86 million in lower amortization of pre-petition debt issuances, amendment and extension costs and discounts due to reclassification of such amounts to liabilities subject to compromise in 2014, 129 partially offset by • • • $405 million in higher expense related to adequate protection payments approved by the Bankruptcy Court for the benefit of TCEH secured creditors in the year ended December 31, 2015 as compared to the post-petition period ended December 31, 2014; $65 million in mark-to-market net gains on interest rate swaps in 2014, and $26 million in higher interest expense on debtor-in-possession financing in the year ended December 31, 2015 as compared to the post-petition period ended December 31, 2014. Income tax benefit totaled $879 million and $2.320 billion on pretax losses in 2015 and 2014, respectively. The effective tax rate was 15.8% in 2015 and 27.1% in 2014.

Predecessor Period from January 1, 2016 through October 2, 2016 — Cash used in operating activities totaled $238 million and was primarily driven by cash used by for margin deposit postings and other working capital utilization. Year Ended December 31, 2015 Compared to Year Ended December 31, 2014 — Cash provided by operating activities totaled $237 million in 2015 compared to cash provided by operating activities of $444 million in 2014. The decrease of $207 million was driven by higher cash used to pay for reorganization costs and higher cash interest payments. Financing Cash Flows Successor Period from October 3, 2016 through December 31, 2016 — Cash provided by financing activities totaled $6 million and related to the net impacts of the Incremental Term Loan B borrowings and the Special Dividend paid to shareholders. Predecessor Period from January 1, 2016 through October 2, 2016 — Cash provided by financing activities totaled $1.059 billion and primarily reflected $2.040 billion in net borrowings under the DIP Roll Facilities and the DIP Facility, including $870 million in net borrowings to fund the Lamar and Forney Acquisition (see Note 6 to the Financial Statements), and $69 million from the issuance of preferred stock, partially offset by $915 million in payments to extinguish claims under the Plan of Reorganization and $112 million in fees related to the issuance of the DIP Roll Facilities. Year Ended December 31, 2015 Compared to Year Ended December 31, 2014 — Cash used in financing activities totaled $30 million in 2015 compared to cash provided by financing activities of $1.111 billion in 2014. Activity in 2015 reflected the repayments of certain debt principal and fees. Activity in 2014 reflected $1.425 billion in borrowings from the DIP Facility, partially offset by $223 million in principal payments for pollution control revenue bonds and $92 million in fees associated with establishment of the DIP Facility. Investing Cash Flows Successor Period from October 3, 2016 through December 31, 2016 — Cash used in investing activities totaled $45 million and was primarily driven by capital expenditures of $48 million and purchases of nuclear fuel of $41 million, partially offset by a reduction in restricted cash balances of $48 million. Capital expenditures, including nuclear fuel, in the period from October 3, 2016 through December 31, 2016 totaled $89 million and consisted of: • • • • $18 million primarily for our generation operations; $22 million for environmental expenditures related to generation units; $41 million for nuclear fuel purchases, and $8 million for information technology and other corporate investments. Predecessor Period from January 1, 2016 through October 2, 2016 — Cash used in investing activities totaled $1.420 billion. Cash used reflected payments of $1.343 billion related to the Lamar and Forney Acquisition net of cash acquired (see Note 6 to the Financial Statements) and capital expenditures (including nuclear fuel purchases) totaling $263 million, partially offset by a $233 million decrease in restricted cash used to backstop letters of credit. 131 Capital expenditures, including nuclear fuel, in the period from January 1, 2016 through October 2, 2016 totaled $263 million and consisted of: • • • • $171 million primarily for our generation operations; $40 million for environmental expenditures related to generation units; $33 million for nuclear fuel purchases, and $19 million for information technology and other corporate investments. Year Ended December 31, 2015 Compared to Year Ended December 31, 2014 — Cash used in investing activities totaled $650 million and $458 million in 2015 and 2014, respectively. Cash used in 2015 reflected capital expenditures (including nuclear fuel purchases) totaling $460 million and a $123 million increase in restricted cash largely for supporting letters of credit issued under the DIP Facility. Cash used in 2014 reflected capital expenditures (including nuclear fuel purchases) totaling $413 million and a $350 million increase in restricted cash supporting letters of credit issued under the DIP Facility, partially offset by $392 million in restricted cash released from an escrow account when certain letters of credit were drawn. Capital expenditures, including nuclear fuel, in 2015 totaled $460 million and consisted of: • • • • $230 million primarily for our generation operations; $82 million for environmental expenditures related to generation units; $123 million for nuclear fuel purchases, and $25 million for information technology and other corporate investments. Debt Activity See Note 13 to the Financial Statements for details of the Vistra Operations Credit Facilities, the DIP Roll Facilities, the DIP Facility and other long-term debt. Available Liquidity The following table summarizes changes in available liquidity for the years ended December 31, 2016 and 2015: Cash and cash equivalents (a) Vistra Operations Credit Facilities — Revolving Credit Facility Vistra Operations Credit Facilities — Term Loan C Facility (b) DIP Roll Revolving Credit Facility DIP Revolving Credit Facility Total liquidity Successor December 31, 2016 843 $ 860 131 — — 1,834 $ $ $ Predecessor October 2, 2016 1,829 — — 750 — 2,579 December 31, 2015 1,400 $ — — — 1,950 3,350 $ ___________ (a) Cash and cash equivalents at December 31, 2016, October 3, 2016 and December 31, 2015 exclude $650 million, $650 million and $1.026 billion, respectively, of restricted cash held for letter of credit support (see Note 22 to the Financial Statements). (b) The Term Loan C Facility is used for issuing letters of credit for general corporate purposes. Borrowings totaling $650 million under this facility were funded to collateral accounts that are reported as restricted cash in the consolidated balance sheet. At December 31, 2016, the restricted cash supported $519 million in letters of credit outstanding, leaving $131 million in available letter of credit capacity (see Note 13 to the Financial Statements). Available liquidity totaled $1.834 billion at December 31, 2016 and reflects cash on hand, the undrawn balance of the Revolving Credit Facility, along with $110 million of incremental revolving credit commitments under the Vistra Operations Credit Facilities entered into in December 2016. The decrease in available liquidity of $771 million in the Predecessor period from January 1, 2016 through October 3, 2016 was primarily driven by $2.040 billion in net borrowings under the DIP Roll Facilities and the DIP Facility, including $870 million in net borrowings to fund the Lamar and Forney Acquisition (see Note 6 to the Financial Statements) $1.064 billion in cash interest payments (including adequate protection payments), $263 million in capital expenditures (including nuclear fuel purchases) and $104 million of cash used to pay for reorganization expenses. 132 Based upon our current internal financial forecasts, we believe that we will have sufficient amounts available under the Vistra Operations Credit Facilities, plus cash generated from operations, to fund our anticipated cash requirements through at least the next 12 months. Capital Expenditures Estimated capital expenditures and nuclear fuel purchases for 2017 are expected to total approximately $307 million and include: • • • $161 million primarily for our generation operations and $31 million for environmental expenditures; $192 million for investments in generation and mining facilities, including approximately: • • $65 million for nuclear fuel purchases; and $50 million for information technology and other corporate investments. Pension and OPEB Plan Funding See Note 18 to the Financial Statements. Liquidity Effects of Commodity Hedging and Trading Activities We have entered into commodity hedging and trading transactions that require us to post collateral if the forward price of the underlying commodity moves such that the hedging or trading instrument we hold has declined in value. We use cash, letters of credit and other forms of credit support to satisfy such collateral posting obligations. See Note 13 to the Financial Statements for discussion of the Vistra Operations Credit Facilities. Exchange cleared transactions typically require initial margin (i.e., the upfront cash and/or letter of credit posted to take into account the size and maturity of the positions and credit quality) in addition to variation margin (i.e., the daily cash margin posted to take into account changes in the value of the underlying commodity). The amount of initial margin required is generally defined by exchange rules. Clearing agents, however, typically have the right to request additional initial margin based on various factors, including market depth, volatility and credit quality, which may be in the form of cash, letters of credit, a guaranty or other forms as negotiated with the clearing agent. Cash collateral received from counterparties is either used for working capital and other business purposes, including reducing borrowings under credit facilities, or is required to be deposited in a separate account and restricted from being used for working capital and other corporate purposes. With respect to over-the-counter transactions, counterparties generally have the right to substitute letters of credit for such cash collateral. In such event, the cash collateral previously posted would be returned to such counterparties, which would reduce liquidity in the event the cash was not restricted. At December 31, 2016, we received or posted cash and letters of credit for commodity hedging and trading activities as follows: • • • • $213 million in cash has been posted with counterparties as compared to $6 million posted at December 31, 2015; $41 million in cash has been received from counterparties as compared to $152 million received at December 31, 2015; $363 million in letters of credit have been posted with counterparties as compared to $230 million posted at December 31, 2015, and $10 million in letters of credit have been received from counterparties as compared to $3 million received at December 31, 2015. 133 Income Tax Matters EFH Corp files a U.S. federal income tax return that, prior to the Effective Date, included the results of our Predecessor, which was classified as a disregarded entity for US federal income tax purposes. Subsequent to the Effective Date, the TCEH Debtors and the Contributed EFH Debtors are no longer included in the EFH Corp. consolidated group and will be included in a consolidated group of which Vistra Energy is the corporate parent. Prior to the Effective Date, EFH Corp. and certain of its subsidiaries (including EFCH and TCEH) were parties to a Federal and State Income Tax Allocation Agreement, which provided, among other things, that any corporate member or disregarded entity in the EFH Corp. group was required to make payments to EFH Corp. in an amount calculated to approximate the amount of tax liability such entity would have owed if it filed a separate corporate tax return. Pursuant to the Plan of Reorganization, the TCEH Debtors and the Contributed EFH Debtors rejected this agreement on the Effective Date. Additionally, since the date of the Settlement Agreement, no further cash payments among the Debtors were made in respect of federal income taxes. EFH Corp. has elected to continue to allocate federal income taxes among the entities that are parties to the Federal and State Income Tax Allocation Agreement. The Settlement Agreement did not alter the allocation and payment for state income taxes, which continued to be settled prior to the Effective Date. The TCEH Debtors and the Contributed EFH Debtors emerged from the Chapter 11 Cases on the Effective Date in a tax- free spin-off from EFH Corp that was part of a series of transactions that included a taxable component, which generated a taxable gain that will be offset with available net operating losses (NOLs) of EFH Corp., substantially reducing the NOLs available to EFH Corp. in the future. As a result of the use of the NOLs, the taxable portion of the transaction resulted in no regular tax liability due and approximately $14 million of alternative minimum tax, payable to the IRS by EFH Corp. Vistra Energy has an obligation to reimburse EFH Corp. 50% of the alternative minimum tax, approximately $7 million, generated from this transaction pursuant to the Tax Matters Agreement. We believe that neither Vistra Energy nor any corporate subsidiary of Vistra Energy is a US real property holding corporation (USRPHC) or has been a USRPHC during the applicable period specified. We do not anticipate that either Vistra Energy or any corporate subsidiary of Vistra Energy will become a USRPHC in the foreseeable future. Generally, a corporation is a USRPHC only if the fair market value of its US real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. There can be no assurance regarding the USRPHC status of Vistra Energy or the corporate subsidiaries of Vistra Energy for the current year or future years, however, because USRPHC status is based on the composition of our assets at the time and on certain rules whose application is uncertain. Income Tax Payments — In the next twelve months, income tax payments related to Texas margin tax are expected to total approximately $19 million, and $7 million in payment of federal income taxes are expected. We received an income tax refund totaling $2 million in the Successor period from October 3, 2016 through December 31, 2016, and made income tax payments totaling $22 million, $29 million and $31 million in the Predecessor period from January 1, 2016 through October 2, 2016 and the years ended December 31, 2015 and 2014, respectively. Capitalization At December 31, 2016, our capitalization ratios consisted of 41% borrowing under the Vistra Energy Operations Facilities and other long-term debt (less amounts due currently) and 59% shareholders' equity. Total borrowings under the Vistra Energy Operations Facilities and other long-term debt to capitalization was 41% at December 31, 2016. Financial Covenants The agreement governing the Vistra Operation Credit Facilities includes a covenant, solely with respect to the Revolving Credit Facility and solely during a compliance period (which, in general, is applicable when the aggregate revolving borrowings and issued revolving letters of credit (in excess of $100 million) exceed 30% of the revolving commitments), that requires the consolidated first lien net leverage ratio not exceed 4.25 to 1.00. Although we had no borrowings under the Revolving Credit Facility as of December 31, 2016, we would have been in compliance with this financial covenant if it was required to be tested at such date. See Note 13 to the Financial Statements for discussion of other covenants related to the Vistra Operations Credit Facilities. 134 Collateral Support Obligations The RCT has rules in place to assure that parties can meet their mining reclamation obligations. In September 2016, the RCT agreed to a collateral bond of up to $975 million to support Luminant's reclamation obligations. The collateral bond is effectively a first lien on all of Vistra Operations' assets (which ranks pari passu with the Vistra Operations Credit Facilities) that contractually enables the RCT to be paid (up to $975 million) before the other first lien lenders in the event of a liquidation of our assets. Collateral support relates to land mined or being mined and not yet reclaimed as well as land for which permits have been obtained but mining activities have not yet begun and land already reclaimed but not released from regulatory obligations by the RCT, and includes cost contingency amounts. The PUCT has rules in place to assure adequate creditworthiness of each REP, including the ability to return customer deposits, if necessary. Under these rules, at December 31, 2016, Vistra Energy has posted letters of credit in the amount of $55 million with the PUCT, which is subject to adjustments. ERCOT has rules in place to assure adequate creditworthiness of parties that participate in the day-ahead, real-time and congestion revenue rights markets operated by ERCOT. Under these rules, Vistra Energy has posted collateral support, in the form of letters of credit, totaling $110 million at December 31, 2016 (which is subject to daily adjustments based on settlement activity with ERCOT). Material Cross Default/Acceleration Provisions Certain of our contractual arrangements contain provisions that could result in an event of default if there were a failure under financing arrangements to meet payment terms or to observe covenants that could or does result in an acceleration of payments due. Such provisions are referred to as "cross default" or "cross acceleration" provisions. A default by Vistra Energy or any of its restricted subsidiaries in respect of certain specified indebtedness in an aggregate amount in excess of $300 million may result in a cross default under the Vistra Operations Credit Facilities. Such a default would allow the lenders to accelerate the maturity of outstanding balances ($4.5 billion at December 31, 2016) under such facilities. Each of Vistra Energy's commodity hedging agreements and interest rate swap agreements that are secured with a lien on its assets on a pari passu basis with the Vistra Operations Credit Facilities lenders contains a cross default provision. An event of a default by Vistra Energy or any of its subsidiaries relating to indebtedness in excess of $300 million that results in the acceleration of such debt, would give each counterparty under these hedging agreements the right to terminate its hedge or interest rate swap agreement with Vistra energy and require all outstanding obligations under such agreement to be settled. Additionally, we enter into energy-related physical and financial contracts, the master forms of which contain provisions whereby an event of default or acceleration of settlement would occur if we were to default under an obligation in respect of borrowings in excess of thresholds, which may vary by contract. Contractual Obligations and Commitments The following table summarizes the amounts and related maturities of our contractual cash obligations at December 31, 2016 (see Notes 13 and 14 to the Financial Statements for additional disclosures regarding these debts and noncancellable purchase obligations). Contractual Cash Obligations: Debt – principal, including capital leases (a) Debt – interest Operating leases Obligations under commodity purchase and services agreements (b) Total contractual cash obligations $ $ Less Than One Year One to Three Years Three to Five Years More Than Five Years 46 223 25 637 931 $ $ 88 442 31 341 902 $ $ 89 433 21 248 791 $ $ 4,380 374 153 733 5,640 $ $ Total 4,603 1,472 230 1,959 8,264 ___________ (a) Includes $4.5 billion of borrowings under the Vistra Operations Credit Facility and $103 million principal amount of long- term debt, including mandatorily redeemable preferred stock and capital leases.

Amounts presented for variable priced contracts reflect the year-end 2016 price for all periods except where contractual price adjustment or index-based prices are specified. The following are not included in the table above: • • • • • the TRA obligation (see Note 10 to the Financial Statements); arrangements between affiliated entities and intercompany debt (see Note 20 to the Financial Statements); individual contracts that have an annual cash requirement of less than $1 million (however, multiple contracts with one counterparty that are more than $1 million on an aggregated basis have been included); contracts that are cancellable without payment of a substantial cancellation penalty, and employment contracts with management Guarantees See Note 14 to the Financial Statements for discussion of guarantees. Off–Balance Sheet Arrangements We do not have any off-balance sheet arrangements. Commitments and Contingencies See Note 14 to the Financial Statements for discussion of commitments and contingencies and legal proceedings. Changes in Accounting Standards See Note 1 to the Financial Statements for discussion of changes in accounting standards. 136 Quantitative and Qualitative Disclosures About Market Risk Market risk is the risk that in the normal course of business we may experience a loss in value as a result of changes in market conditions that affect economic factors such as commodity prices, interest rates and counterparty credit. Our exposure to market risk is affected by a number of factors, including the size, duration and composition of our energy and financial portfolio, as well as the volatility and liquidity of markets. Instruments used to manage this exposure include interest rate swaps to hedge debt costs, as well as exchange-traded, over-the-counter contracts and other contractual arrangements to hedge commodity prices. Risk Oversight We manage the commodity price, counterparty credit and commodity-related operational risk related to the competitive energy business within limitations established by senior management and in accordance with overall risk management policies. Interest rate risk is managed centrally by our treasury function. Market risks are monitored by risk management groups that operate independently of the wholesale commercial operations, utilizing defined practices and analytical methodologies. These techniques measure the risk of change in value of the portfolio of contracts and the hypothetical effect on this value from changes in market conditions and include, but are not limited to, position reporting and review, Value at Risk (VaR) methodologies and stress test scenarios. Key risk control activities include, but are not limited to, transaction review and approval (including credit review), operational and market risk measurement, transaction authority oversight, validation of transaction capture, market price validation and reporting, and portfolio valuation and reporting, including mark-to-market valuation, VaR and other risk measurement metrics. Vistra Energy has a risk management organization that enforces applicable risk limits, including the respective policies and procedures to ensure compliance with such limits, and evaluates the risks inherent in our businesses. Commodity Price Risk Our business is subject to the inherent risks of market fluctuations in the price of electricity, natural gas and other energy- related products it markets or purchases. We actively manage the portfolio of generation assets, fuel supply and retail sales load to mitigate the near-term impacts of these risks on results of operations. Similar to other participants in the market, we cannot fully manage the long-term value impact of structural declines or increases in natural gas and power prices. In managing energy price risk, we enter into a variety of market transactions including, but not limited to, short- and long- term contracts for physical delivery, exchange-traded and over-the-counter financial contracts and bilateral contracts with customers. Activities include hedging, the structuring of long-term contractual arrangements and proprietary trading. We continuously monitor the valuation of identified risks and adjust positions based on current market conditions. We strive to use consistent assumptions regarding forward market price curves in evaluating and recording the effects of commodity price risk. VaR Methodology — A VaR methodology is used to measure the amount of market risk that exists within the portfolio under a variety of market conditions. The resultant VaR produces an estimate of a portfolio's potential for loss given a specified confidence level and considers, among other things, market movements utilizing standard statistical techniques given historical and projected market prices and volatilities. A Monte Carlo simulation methodology is used to calculate VaR and is considered by management to be the most effective way to estimate changes in a portfolio's value based on assumed market conditions for liquid markets. The use of this method requires a number of key assumptions, such as use of (i) an assumed confidence level; (ii) an assumed holding period (i.e., the time necessary for management action, such as to liquidate positions); and (iii) historical estimates of volatility and correlation data. The tables below detail certain VaR measures related to various portfolios of contracts. VaR for Energy-Related Contracts Subject to Mark-to-Market (MtM) Accounting — This measurement estimates the potential loss in fair value, due to changes in market conditions, of all contracts marked-to-market in net income, based on a 95% confidence level and an assumed holding period of 60 days. Month-end average MtM VaR: Month-end high MtM VaR: Month-end low MtM VaR: 137 Successor Predecessor December 31, 2016 December 31, 2015 $ $ $ 65 119 30 $ $ $ 68 97 49 The increase in the month-end high MtM VaR risk measure reflected increased price volatility. Interest Rate Risk The following table provides information concerning our financial instruments at December 31, 2016 and 2015 that are sensitive to changes in interest rates. Debt amounts of the Successor consist of the Vistra Operations Credit Facilities. Debt amounts of the Predecessor consist of debtor-in-possession financing and pre-petition obligations that were fully secured and other obligations that were allowed to be paid as ordered by the Bankruptcy Court. Other pre-petition obligations (i.e., obligations incurred or accrued prior to the Bankruptcy Filing) were administered by the Bankruptcy Court and are excluded from the Predecessor debt amounts presented below due to the uncertainty related to when those obligations would mature. See Note 13 to the Financial Statements for further discussion of these financial instruments.

(b) The weighted average interest rate presented is based on the rates in effect at December 31, 2016. (c) Successor period includes interest rate swaps that become effective in January 2017 and have maturity dates through July 2023. Credit Risk Credit risk relates to the risk of loss associated with nonperformance by counterparties. We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies prescribe practices for evaluating a potential counterparty's financial condition, credit rating and other quantitative and qualitative credit criteria and authorize specific risk mitigation tools including, but not limited to, use of standardized master agreements that allow for netting of positive and negative exposures associated with a single counterparty. We have processes for monitoring and managing credit exposure of our businesses including methodologies to analyze counterparties' financial strength, measurement of current and potential future exposures and contract language that provides rights for netting and setoff. Credit enhancements such as parental guarantees, letters of credit, surety bonds, margin deposits and customer deposits are also utilized. Additionally, individual counterparties and credit portfolios are managed to assess overall credit exposure. Credit Exposure — Our gross exposure to credit risk associated with trade accounts receivable (retail and wholesale) and net asset positions (before collateral) arising from commodity contracts and hedging and trading activities totaled $798 million at December 31, 2016. The components of this exposure are discussed in more detail below. 138 Assets subject to credit risk at December 31, 2016 include $439 million in retail trade accounts receivable before taking into account cash deposits held as collateral for these receivables totaling $48 million. The risk of material loss (after consideration of bad debt allowances) from nonperformance by these customers is unlikely based upon historical experience. Allowances for uncollectible accounts receivable are established for the potential loss from nonpayment by these customers based on historical experience, market or operational conditions and changes in the financial condition of large business customers. The remaining credit exposure arises from wholesale trade receivables and amounts associated with derivative instruments related to hedging and trading activities. Counterparties to these transactions include energy companies, financial institutions, electric utilities, independent power producers, oil and gas producers, local distribution companies and energy marketing companies. At December 31, 2016, the exposure to credit risk from these counterparties totaled $359 million consisting of accounts receivable of $153 million and net asset positions related to commodity contracts of $206 million, after taking into account the netting provisions of the master agreements described above but before taking into account $50 million in collateral (cash, letters of credit and other credit support). The net exposure (after collateral) of $309 million increased $95 million in the year ended December 31, 2016. Of this $309 million net exposure, 95% is with investment grade customers and counterparties, as determined by our internal credit evaluation process which includes publicly available information including major rating agencies' published ratings as well as internal credit methodologies and credit scoring models. The company routinely monitors and manages credit exposure to these customers and counterparties based on, but not limited to, the assigned credit rating, margining and collateral management. The following table presents the distribution of credit exposure at December 31, 2016. This credit exposure largely represents wholesale trade accounts receivable and net asset positions related to commodity contracts and hedging and trading activities recognized as derivative assets in the condensed consolidated balance sheets, after taking into consideration netting provisions within each contract, setoff provisions in the event of default and any master netting contracts with counterparties. Credit collateral includes cash and letters of credit, but excludes other credit enhancements such as liens on assets. See Note 17 to the Financial Statements for further discussion of portions of this exposure related to activities marked-to-market in the financial statements.

Such contractual commitments may contain pricing that is favorable considering current market conditions and therefore represent economic risk if the counterparties do not perform. Nonperformance could have a material impact on future results of operations, liquidity and financial condition. Significant (10% or greater) concentration of credit exposure exists with three counterparties, which represented 26%, 18% and 15% of the $309 million net exposure. We view exposure to these counterparties to be within an acceptable level of risk tolerance due to the counterparties' credit ratings, each of which is rated as investment grade, the counterparties' market role and deemed creditworthiness and the importance of our business relationship with the counterparties. An event of default by one or more counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts such as margin deposits are owed to the counterparties or delays in receipts of expected settlements owed to us. While the potential concentration of risk with these counterparties is viewed to be within an acceptable risk tolerance, the exposure to hedge counterparties is managed through the various ongoing risk management measures described above. 139 Forward-Looking Statements This report and other presentations made by us contain "forward-looking statements." All statements, other than statements of historical facts, that are included in this report, or made in presentations, in response to questions or otherwise, that address activities, events or developments that may occur in the future, including such matters as activities related to our financial or operational projections, capital allocation, capital expenditures, liquidity, dividend policy, business strategy, competitive strengths, goals, future acquisitions or dispositions, development or operation of power generation assets, market and industry developments and the growth of our businesses and operations (often, but not always, through the use of words or phrases such as "intends," "plans," "will likely," "unlikely," "expected," "anticipated," "estimated," "should," "may," "projection," "target," "goal," "objective" and "outlook"), are 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 risks and is qualified in its entirety by reference to the discussion under Item 16, Management's Discussion and Analysis in this report and the following important factors, among others, that could cause results to differ materially from those projected in or implied by such forward-looking statements: • • • the actions and decisions of regulatory authorities; prohibitions and other restrictions on our operations due to the terms of our agreements; prevailing governmental policies and regulatory actions, including those of the Texas Legislature, the Governor of Texas, the US Congress, the FERC, the NERC, the TRE, the PUCT, the RCT, the NRC, the EPA, the TCEQ, the US Mine Safety and Health Administration and the CFTC, with respect to, among other things: allowed prices; industry, market and rate structure; purchased power and recovery of investments; operations of nuclear generation facilities; operations of fossil fueled generation facilities; operations of mines; acquisition and disposal of assets and facilities; development, construction and operation of facilities; decommissioning costs; present or prospective wholesale and retail competition; changes in tax laws and policies; changes in and compliance with environmental and safety laws and policies, including National Ambient Air Quality Standards, the CSAPR, the MATS, regional haze program implementation and GHG and other climate change initiatives, and clearing over-the-counter derivatives through exchanges and posting of cash collateral therewith; legal and administrative proceedings and settlements; general industry trends; economic conditions, including the impact of an economic downturn; • • • • weather conditions, including drought and limitations on access to water, and other natural phenomena, and acts of • • • • • • • • • • • • • • • sabotage, wars or terrorist or cyber security threats or activities; our ability to collect trade receivables from counterparties; our ability to attract and retain profitable customers; our ability to profitably serve our customers; restrictions on competitive retail pricing; changes in wholesale electricity prices or energy commodity prices, including the price of natural gas; changes in prices of transportation of natural gas, coal, fuel oil and other refined products; changes in the ability of vendors to provide or deliver commodities as needed; changes in market heat rates in the ERCOT electricity market; our ability to effectively hedge against unfavorable commodity prices, including the price of natural gas, market heat rates and interest rates; population growth or decline, or changes in market supply or demand and demographic patterns, particularly in ERCOT; access to adequate transmission facilities to meet changing demands; changes in interest rates, commodity prices, rates of inflation or foreign exchange rates; changes in operating expenses, liquidity needs and capital expenditures; commercial bank market and capital market conditions and the potential impact of disruptions in US and international credit markets; access to capital, the attractiveness of the cost and other terms of such capital and the success of financing and refinancing efforts, including availability of funds in capital markets; 140 • • • • • • • • • • • • our ability to maintain prudent financial leverage; our ability to generate sufficient cash flow to make principal and interest payments in respect of, or refinance, our debt obligations: competition for new energy development and other business opportunities; inability of various counterparties to meet their obligations with respect to our financial instruments; changes in technology (including large scale electricity storage) used by and services offered by us; changes in electricity transmission that allow additional power generation to compete with our generation assets; our ability to attract and retain qualified employees; significant changes in our relationship with our employees, including the availability of qualified personnel, and the potential adverse effects if labor disputes or grievances were to occur; changes in assumptions used to estimate costs of providing employee benefits, including medical and dental benefits, pension and OPEB, and future funding requirements related thereto, including joint and several liability exposure under ERISA; hazards customary to the industry and the possibility that we may not have adequate insurance to cover losses resulting from such hazards; the impact of our obligations under the TRA, and actions by credit rating agencies. 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 or circumstances. New factors emerge from time to time, and it is not possible for us to predict them. In addition, we may be unable to assess the impact of any such event or condition or the extent to which any such event or condition, or combination of events or conditions, may cause results to differ materially from those contained in or implied by any forward-looking statement. As such, you should not unduly rely on such forward-looking statements. Market for Our Common Stock Currently, our common stock is quoted on the OTCQX US market under the symbol "VSTE". The market for our common stock is limited and we cannot assure that a larger market will ever be developed or maintained. Securities quoted on the OTCQX US market may experience low trading volumes. As a result, investors may find it difficult to dispose of, or to obtain accurate quotations of the price of, our securities. This may limit the liquidity of the common stock, and may adversely affect the market price of our common stock. Further, the purchase or sale of a relatively small number of securities could result in significant price fluctuations and it may be difficult for holders to sell their securities without depressing the market price for such securities. Industry and Market Information Certain industry and market data and other statistical information used throughout this report are based on independent industry publications, government publications, reports by market research firms or other published independent sources, including certain data published by ERCOT, the PUCT and NYMEX. We did not commission any of these publications, reports or other sources. Some data is also based on good faith estimates, which are derived from our review of internal surveys, as well as the independent sources listed above. Industry publications, reports and other sources generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. While we believe that each of these studies and publications, reports and other sources is reliable, we have not independently investigated or verified the information contained or referred to therein and make no representation as to the accuracy or completeness of such information. Forecasts are particularly likely to be inaccurate, especially over long periods of time, and we do not know what assumptions were used in preparing such forecasts. Statements regarding industry and market data and other statistical information used throughout this report involve risks and uncertainties and are subject to change based on various factors. 141 Item 17: List of securities offerings and shares issued for services in the past two years.

On the Third Amendment Effective Date, the Credit Agreement is hereby amended as follows: (i) The definition of “Term C Loan Collateral Account” in Section 1.1 of the Credit Agreement is hereby amended and restated in its entirety as follows: “Term C Loan Collateral Account” shall mean one or more cash collateral accounts or securities accounts established pursuant to, and subject to the terms of, Section 3.9 for the purpose of cash collateralizing the Term L/C Obligations in respect of Term Letters of Credit, including the Deutsche Bank Term C Loan Americas 92513965 Collateral Account, the Barclays Term C Loan Collateral Account, the Natixis Term C Loan Collateral Account and the Citibank Term C Loan Collateral Account. (ii) The definition of “Term Letter of Credit Issuer” in Section 1.1 of the Credit Agreement is hereby amended and restated in its entirety as follows: “Term Letter of Credit Issuer” shall mean (a) Deutsche Bank AG New York Branch and any of its Affiliates (in the case of such Affiliates, solely to the extent reasonably acceptable to the Borrower), (b) Barclays Bank PLC and any of its Affiliates (in the case of such Affiliates, solely to the extent reasonably acceptable to the Borrower), (c) Natixis, New York Branch and any of its Affiliates (in the case of such Affiliates, solely to the extent reasonably acceptable to the Borrower), (d) each issuer of a DIP Term Letter of Credit listed on Schedule 1.1(b) and (e) at any time such Person who shall become a Term Letter of Credit Issuer pursuant to Section 3.6 (it being understood that if any such Person ceases to be a Lender hereunder, such Person will remain a Term Letter of Credit Issuer with respect to any Term Letters of Credit issued by such Person that remained outstanding as of the date such Person ceased to be a Lender).
