Explanatory Note

This Amendment No. 1 to Form 10-K (this Amendment) amends the Annual Report on Form 10-K for the fiscal year ended December 31, 2017 (fiscal 2017) of Dynegy Inc., as originally filed with the Securities and Exchange Commission (SEC) on February 22, 2018 (the
Original Form 10-K). We are filing this Amendment to present the information required by Part III of Form 10-K that was previously omitted from the Original
Form 10-K in reliance on General Instruction G(3) to Form 10-K because a definitive proxy statement containing such information will not be filed within 120 days after
the end of fiscal 2017. This Amendment restates in their entirety Items 10, 11, 12, 13 and 14 of the Original Form 10-K and the exhibit index set forth in Part IV of the Original Form 10-K and includes certain exhibits as noted thereon. The cover page of the Original Form 10-K is also amended to delete the reference to the incorporation by reference of the
registrants definitive proxy statement.

An amended Exhibit 23.1 is being filed herewith to include the signature of Ernst & Young LLP, which was
inadvertently omitted from that exhibit filed with the Original Form 10-K. In addition, Item 15 of Part IV has been amended to include new certifications pursuant to Section 302 of the Sarbanes-Oxley Act
of 2002 by our principal executive officer and principal financial officer as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the Exchange Act). Because no financial
statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications
have been omitted. The certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 of our principal executive officer and principal financial officer are filed with this Amendment as Exhibits 31.3 and 31.4 hereto.

Except as expressly set forth herein, this Amendment does not otherwise update information in the Original Form 10-K to reflect
facts or events occurring subsequent to the filing date of the Original Form 10-K. This Amendment should be read in conjunction with the Original Form 10-K and with the
registrants filings with the SEC subsequent to the filing of the Original Form 10-K.

Unless the context indicates
otherwise, throughout this report, the terms Dynegy, the Company, we, us, our, and ours are used to refer to Dynegy Inc. and its direct and indirect subsidiaries. Terms used but
not defined herein are as defined in the Original Form 10-K.

Merger with and into Vistra
Energy & Expected Form 15 Filing

On April 9, 2018 (the Closing Date), pursuant to the Merger Agreement, Dynegy merged with and into
Vistra Energy Corp. (Vistra Energy), with Vistra Energy continuing as the surviving corporation (the Merger). The combined company will operate under the name Vistra Energy Corp. and will continue to be a Delaware
corporation. At the effective time of the Merger (the Merger Effective Time), each issued and outstanding share of the Companys common stock, par value $0.01 per share (Dynegy Common Stock) (other than shares owned by
Vistra Energy or its wholly owned subsidiaries, held in treasury by the Company or held by a wholly owned subsidiary of the Company, which shares were automatically cancelled and ceased to exist) was automatically converted into the right to receive
0.652 shares of Vistra Energys common stock, par value $0.01 per share (Vistra Energy Common Stock, and such ratio of Dynegy Common Stock to Vistra Energy Common Stock, the Exchange Ratio). Unless the context indicates
otherwise, information presented herein is as of April 8, 2018.

As a result of the Merger, Dynegy intends to file a Form 15 with respect to all of its
registered classes of securities immediately following the filing of this Amendment to terminate the registration of such securities under Section 12(g) of the Exchange Act and suspend the duty of Dynegy to file reports under Sections 13 and
15(d) of the Exchange Act. As a result of such termination and suspension, Dynegy will no longer be required to file reports under Sections 13 and 15(d) of the Exchange Act. Prior to the filing of such Form 15, SEC rules and regulations require
Dynegy to first file this Amendment in order to complete Dynegys Original Form 10-K and be current in its Exchange Act reporting obligations. After the filing of this Amendment, Dynegy no longer intends
to file any reports under Sections 13 and 15(d) of the Exchange Act.

AUDIT COMMITTEE

As of
April 8, 2018, the members of the Audit Committee were: John R. Sult (Chair), Paul Barbas and Hilary Ackerman. Each member of the Audit Committee was independent as such term is defined in the NYSE and SEC rules. The Board had determined that
each member of the Audit Committee possessed the necessary level of financial literacy required to enable him or her to serve effectively as an Audit Committee member, and all members qualified as Audit Committee Financial Experts, including our
designated Financial Expert, Mr. Sult, our Audit Committee Chair. No Audit Committee member served on more than three audit committees of public companies, including our Audit Committee.

CODE OF BUSINESS CONDUCT AND ETHICS

Our Code of Business Conduct and Ethics
applies to all of our directors, officers and employees. The key principles of this code include acting legally and ethically, notifying appropriate persons upon becoming aware of issues, obtaining confidential advice and dealing fairly with our

EXECUTIVE SUMMARY

The
Compensation Committee is committed to sound compensation and corporate governance practices. It further believes the decisions regarding 2017 compensation were made to ensure continued alignment of executive compensation with the Companys
results, strategic, operational and financial accomplishments and the long-term interests of our stockholders.

Our long-term incentive, or LTI, awards are
substantially performance-based aligned with stockholder interests. Our short-term incentive, or STI, plan is designed to reward the achievement of annual performance objectives critical to Dynegys success. These objectives are determined
annually based on an in-depth strategic planning process with the Board of Directors and the Executive Management Team and progress is reviewed frequently throughout the year. For 2017, the objectives were
categorized across five critical success factors weighted as follows for the purposes of determining STI funding for the year (Operations: 20% weighting; Strengthen the Balance Sheet: 30% weighting; Commercial and Retail: 25% weighting; Regulatory:
20% weighting; and Workforce Positioned to Succeed: 5% weighting).

The Compensation Committee and full Board reviewed LTI performance unit metrics and progress
along the above STI objectives throughout the year and the Companys and Named Executive Officers accomplishments in these areas impacted our compensation decisions and pay outcomes in 2017 as described below:



|● |  | Our STI plan achieved a quantitative result equal to 100.5% of target based on results relative to our pre-established goals.
|- |  | -----------------------------------------------------------------------------------------------------------------------------



|● |  | The Compensation Committee had continued the use of performance shares as the largest component of the 2017 LTI awards for our Named Executive Officers.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



|● |  | The PSUs granted in 2015 (covering the 2015-2017 performance period) resulted in no payment, as the Companys total stockholder return, or TSR, performance threshold was not achieved.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|● |  | PSUs granted in 2016 and 2017 included a second performance metric: cumulative Free Cash Flow, or FCF. This second metric was added to enhance the line of sight for our management team, further align pay and performance
and in response to feedback we received from some of our largest stockholders.
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

BUSINESS STRATEGY AND COMPANY PERFORMANCE

The Compensation Committee believes that our compensation plans and policies are well-designed and structured to ensure that the
compensation of our Named Executive Officers supports our compensation philosophy and objectives, which focus on pay and performance, alignment with stockholder value and market competiveness. This is especially important as the Compensation
Committee balances executive compensation decisions that reward performance, while recognizing the challenges stockholders in the Independent Power Producer, or IPP, industry have faced.

During 2017, we proactively managed aspects of our business that were within our direct control, including strengthening the balance sheet, cost management, operations
and portfolio management, and took an active and vocal leadership role on the regulatory front at the state and national level. Notable highlights from the past year include:



| | ● |  | Repaid/refinanced $1.25 billion of the 2019 debt maturity and repriced secured debt twice, reducing LIBOR spread by 1.25% and saving $25 million in interest expense per year.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Completed the GENCO subsidiary financial restructuring, eliminating $825 million of unsecured Genco bonds in exchange for a portion of cash, notes and warrants.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ● |  | Closed the Engie acquisition and exceeded the synergy target of $90 million.
| | - |  | ----------------------------------------------------------------------------



| | ● |  | Achieved top decile safety performance and significantly reduced the severity of injuries (SIF) across the fleet.
| | - |  | -----------------------------------------------------------------------------------------------------------------



| | ● |  | Exercised cost management measures across the fleet to help mitigate margin losses due to market decline and/or reliability issues.

Pay for Performance

The total
compensation for each Named Executive Officer provides reasonable upside potential based on performance as well as risk of no payment when performance objectives are not achieved. Our compensation structure includes a competitive base salary and
performance based STI and LTI awards that are aligned with stockholder interests.

For 2017, the mix of pay across base salary, STI, and LTI for the CEO and the
other Named Executive Officers was heavily weighted towards at-risk pay. As the two charts below illustrate, a total of 86% of total compensation allocated to Mr. Flexon, and 71% of the total compensation
allocated to the other NEOs, was at-risk.

this time period, we have seen the continuation of a low commodity price environment, significant shifts in the regulatory environment and a change in the stock price valuation for companies in the IPP sector. Over the course of this time period,
the Compensation Committee has sought to structure our executive compensation programs to reward our Named Executive Officers for the accomplishment of strategic and annual business objectives, while demonstrating alignment with sustainable
long-term stockholder value.

Reported Pay.In the first quarter of each year, the Compensation Committee establishes the annual compensation opportunities
for the Named Executives. Decisions regarding base salary, annual STI targets and LTI awards are based on competitive pay levels and practices, Dynegys prior year performance, the executives individual performance, and progress on the
execution of the Companys strategic plan. Since our emergence from bankruptcy in 2012, Dynegy has made significant progress in enhancing the Companys ability to generate long-term value for stockholders. The impact of acquisitions and
other portfolio management decisions, cost reduction efforts, the realization of operational efficiencies and other actions within managements control has positioned the Company for future success. Chart 1 illustrates the nearly 5X growth in
Adjusted EBITDA1 and generation capacity since 2013. In recognition of these results, during this time period the Compensation Committee has made moderate increases to Mr. Flexons
annual total compensation (excluding the one-time equity grant made in May 2015 in connection with execution of his amended employment contract), as shown in Chart 2.





1We define Adjusted EBITDA as
EBITDA adjusted to exclude (i) gains or losses on the sale of certain assets, (ii) the impacts of mark-to-market changes on derivatives related to our
generation portfolio, as well as warrants, (iii) the impact of impairment charges: certain amounts such as those associated with the acquisitions, dispositions, and restructurings (v) non-cash
compensation expenses (vi) gains or losses related to modification or extinguishment of debt, and (vii) other material or unusual items. For a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial
measure, for fiscal years 2015, 2016 and 2017, see Part II, Item 7. Managements Discussion and Analysis of Financial Condition and Results of OperationsResults of Operations of the Original Form
10-K and for a reconciliation of Adjusted EBITDA to net income for fiscal years 2013 and 2014, see Part II, Item 7. Managements Discussion and Analysis of Financial Condition and Results of
OperationsResults of Operations of our Annual Report on Form 10-K for the fiscal year ended 2014.

Executive Officers establish strong alignment with stockholders, and such awards are working as intended. The average realizable value of these awards is approximately 40% of their reported value, as measured on December 31, 2017.

EXECUTIVE COMPENSATION PROGRAM OVERVIEW

Philosophy and Objectives of
our Executive Compensation Programs

The executive compensation program, administered by the Compensation Committee, is designed to attract, motivate and
retain a highly qualified Executive Management Team capable of effectively managing and growing our business. Our executive compensation program reflects a fundamental belief that rewards should be competitive, both in elements and amount, with the
broad labor market in which we compete for executive talent and commensurate with the Company and the individual executives performance. The primary objectives of our executive compensation program are:



●

Pay for PerformanceOur total compensation for each individual provides reasonable upside potential for exceptional performance; as well as risk of no payment, with respect to incentive compensation, when
performance objectives are not achieved. Our variable pay programs are designed as forward-looking incentives that reflect individual and corporate performance during the year under review.  ●

Alignment with Stockholder ValueOur LTI awards encourage share price improvement and a strong link to stockholder interests. Our compensation programs are designed and administered to maximize
stockholder value.  ●

Market CompetivenessOur overall compensation strategy recognizes that attraction and retention of key talent is critical. A market competitive pay program is necessary to the attainment of our stated
business goals and objectives and to the creation of value for our stockholders.


The Compensation Committee considers these objectives in
making decisions regarding the design of our executive compensation program, as well as the level and structure of pay for our Named Executive Officers.

Elements of our Executive Compensation Program

The Compensation
Committee strives to promote a pay for performance culture. The executive compensation program was designed to incorporate three primary elements: base salary, STI, and LTI awards.

Peer Group and Benchmarking

The
Compensation Committee uses compensation benchmarking data to provide a competitive market context to its decisions regarding compensation for the Named Executive Officers. To assist the Compensation Committee with setting 2017 target compensation
levels, Meridian Compensation Partners, LLC, or Meridian, prepared a benchmarking review to assess the competitiveness of each element of compensation for the Named Executive Officers, and to provide information regarding incentive plan designs and
pay practices within the energy industry.

The Compensation Committee reviewed and discussed the benchmarking data, and used the data to inform its compensation
decisions. The Compensation Committee believes the combination of these two data perspectives offers an appropriate and credible basis for benchmarking the compensation of the Named Executive Officers. The Committee will continue to evaluate this
approach and available data sources, and make changes as appropriate.





2We define Free Cash Flow in the 2017 award agreements as cash flow from operations less non-discretionary maintenance
and environmental capital expenditures, the cash impact of acquisition-related fees and financing costs plus the return of restricted cash. Free Cash Flow also includes receipts or payments related to interest rate swaps, excludes the impact of
changes in collateral and working capital and excludes certain capital costs related to compliance with environmental requirements.

##### Table of Contents

The benchmarking approach for the 2017-2018 benchmarking cycle uses two sources of market data to assess the
competitiveness of Dynegys executive compensation programinformation contained in the public disclosures of a selected group of peer companies, and data from the 2017 Equilar Executive Compensation Survey database.

Selection of the peer companies presents certain challenges due to the limited number of directly comparable companies. Dynegy operates in competitive wholesale and
retail markets as an IPP. Given the relatively small number of direct competitors, the Committee has expanded the peer group to include companies from three segments of the power generation industrypublicly traded independent power producers,
electric utilities and multi-utilities who both possess competitive power generation operations to provide a more robust and statistically significant peer group. Specific factors considered in selection
of the peer group include:



|● |  | Financial and Operational Metricsassets, revenues, market capitalization, enterprise value;
|- |  | --------------------------------------------------------------------------------------------



|● |  | Operational Scopemerchant generation capacity, industry segment, commercial, retail and commodity focus;
|- |  | ---------------------------------------------------------------------------------------------------------



|● |  | Market-Based Factorslabor market requirements (e.g., finance, operations, commercial), competition for executive talent, comparability of pay data; and
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



|● |  | External stockholder and governance evaluations of Dynegys pay levels and practices.
|- |  | -------------------------------------------------------------------------------------

The resulting selection of
peer companies attempts to balance the above considerations with the need to identify companies that similarly face the unique challenges of the power generation market. The 2017 peer group consists of nine companies, plus Dynegy, that operate
merchant power businesses, with revenues ranging from $1.4 billion to $28.6 billion (median revenues of $10.2 billion).



|                                                                                                                        |  |                                                                             |  |

Companies                                                                                                         
|IPPs                                                                                                                    |  | Electric Utilities                                                          |  | Multi-Utilities                         
|●   AES Corporation
●   Calpine Corporation
●   Capital Power Corporation
●   NRG Energy Inc.
●   TransAlta Corporation |  | ●   Entergy Corporation ●   Exelon Corporation ●   First Energy Corporation |  | ●   Public Service Enterprise Group Inc.

In 2017, one company was removed from the peer group (Talen Energy), while one firm was added (TransAlta Corporation). These changes
were intended to further refine the benchmarking group, however our peer group is still comprised of companies that vary with respect to their core business model. The IPP peers operate portfolios that generate power in competitive, deregulated
markets, while the utility peer companies operate portfolios that are also supported by a regulated rate base. Additionally, the increase in state regulatory actions, that in some instances have resulted in out-of-market subsidies for utility-owned generation facilities, have further contributed to uneven competitive landscape across the companies that comprise our peer group.

The Compensation Committee reviews benchmark compensation data for the Named Executive Officers, based on position matches developed from analyses of publicly-disclosed
data from the peer group companies and supplemental benchmark data derived from the Equilar Executive Compensation Survey. This survey analysis included data from 32 energy industry companies with median revenues of $6.6 billion and 187 general
industry companies with median revenues of $4.7 billion. A listing of the companies included in the survey data is provided in the table in Annex A.

The
Compensation Committee does not target specific percentiles within the benchmark data provided by these sources when making compensation decisions. Rather, the Compensation Committee determines the appropriate competitive positioning for each Named
Executive Officer based on a variety of factors including market data, individual expertise and individual performance and corporate performance.

Stockholder Outreach and Say on Pay Results

Dynegy has maintained regular, year-round engagement with top stockholders through investor relations activities involving several members of our executive management
team. These activities include quarterly earnings calls, conferences, face-to-face visits and other communication channels. Our outreach efforts, which covered updates
to our strategic focus, executive compensation and overall governance practices, included discussions with several of our largest stockholders. These discussions provided feedback, on a number of areas, in support of the overall structure of our
executive compensation program, and also highlighted the need to continue to more clearly explain the link between our business results with executive compensation decisions. We focused on such suggested disclosures and incorporated a number of
suggested changes herein. We designed 2017 pay to address some stockholder concerns resulting in 80% Say on Pay results in 2017.

The primary participants in these
discussions were our Compensation Committee Chair, our Chief Administrative Officer and members of our Human Resources, Legal and Investor Relations teams.

The Compensation Committee recommended increases for Mr. Flexon, Mr. Freeland, Ms. Burke, Ms. James, and
Mr. Jones consistent with the merit adjustment budget that was provided to non-represented employees and comparable to the peer market levels relative to their individual performance. The Compensation
Committee sought to adjust Mr. Joness salary upward in the competitive benchmark range commensurate with his experience and performance, and as such recommended a base salary adjustment, which was subsequently approved by the full Board.

Short-Term Incentive (STI) Plan

The Dynegy Inc. Incentive
Compensation Plan, or STI Plan, serves as a variable, at-risk mechanism to reward our Named Executive Officers and other eligible employees for the achievement of annual performance objectives critical to our
success. The STI Plan emphasizes pay for performance by providing cash awards for the achievement of pre-determined levels of Company performance. Annual STI awards are paid from a performance-based bonus pool designed to fund STI awards paid to our Named Executive Officers and other executives as determined through the STI Plan, and to allow for full tax deductibility of such STI awards.

Individual STI Targets. The Compensation Committee reviews the STI target bonus opportunities for each Named
Executive Officer on an annual basis, and may make adjustments to reflect changes in an individual role or to maintain competitive alignment. The Compensation Committee believes the target STI opportunities for 2017 were appropriately positioned
relative to competitive benchmark levels and remain unchanged from 2016. The 2017 STI targets for each of the Named Executive Officers, expressed as a percentage of base salary, were as follows:

The design of the STI Plan provided each of our Named Executive Officers with the opportunity to earn up to a maximum of
200% of their individual STI target, based on the Companys performance relative to pre-established performance components and levels of achievement.

STI Performance Objectives.Each year, the Board of Directors, the Executive Management Team, and internal and external subject matter experts convene to review,
discuss and determine the Companys five-year Strategic Plan. The key priorities required to accomplish our strategic plan form the basis for our annual business objectives, which we refer to as Critical Success Factors. Each of the Critical
Success Factors is weighted, and performance is measured against year-end performance to determine the overall funding for the STI program.

For 2017, the Committee approved five Critical Success Factors that were identified in the Strategic Plan to form the basis of performance goals under the STI Plan (see
table below). These Critical Success Factors were focused on being the safest, most reliable, lowest-cost platform in the industry while optimizing the portfolio through PRIDE, strengthening the balance sheet, and reducing debt. Performance goals
under Strengthen Balance Sheet, Commercial & Retail, Operations, and Workforce Positioned to Succeed (which collectively had an 80% weighting) included quantifiable performance metrics. In contrast, the performance goals under Regulatory
(which had a 20% weighting) included subjective performance metrics. At the start of the year, the Committee established specific goals that defined threshold, target and maximum performance levels. Details regarding the specific performance goals
are provided below in the section called 2017 STI Results.



|                                |  |          
|------------------------------- |  | ---------
|Critical Success Factors        |  | Weighting
|Strengthen Balance Sheet        |  | 30%      
|Operations                      |  | 20%      
|Commercial & Retail             |  | 25%      
|Regulatory                      |  | 20%      
|Workforce Positioned to Succeed |  | 5%       

Throughout the year, the Compensation Committee was provided with updates on progress against these performance goals. At the end of the
year, the Compensation Committee reviewed achieved performance and determines the percentage of target payout earned as a result of this performance.

STI
Funding Gate.In order for our annual STI Plan to be funded at any performance level, a minimum level of performance must be first achieved. In the first quarter of each year, the Compensation Committee established this funding gate
based on a key financial performance metric. If this funding gate metric is not achieved, the STI program will not be funded, resulting in no STI payout to any employee, including our Named Executive Officers. For 2017, the Compensation Committee
approved the funding gate of $47 million of FCF.

2017 STI Results. In February 2018, the Compensation Committee determined that the 2017 funding gate
had been successfully achieved. The Compensation Committee then reviewed the Companys performance relative to the 2017 Critical Success Factors and performance metrics and certified the quantitative result as 100.5% of target. The performance
results were reviewed and confirmed by the Companys Internal Audit team. The detailed performance results relative to the Critical Success Factors are summarized below:

Long-Term Incentive (LTI) Awards

Our LTI awards focus on the attainment of long-term performance goals and objectives, which are deemed instrumental in creating
value for stockholders and supporting retention incentives for our executives. The Compensation Committee reviews the LTI targets each year for competitive alignment. The Compensation Committee also reviews market trends related to the award mix and
determines the appropriate target LTI value and mix of equity instruments considering market benchmark data.

In February 2017, the Compensation Committee approved
each Named Executive Officers 2017 target grant value and the allocation of this value among the following LTI awards (based on award values): 35% RSUs, 25% stock options, and 40% PSUs. The Compensation Committee believes this mix of LTI
instruments provides performance incentives that are aligned with stockholder interest and retention incentives for our Named Executive Officers.

The awards for
Mr. Freeland, Ms. Burke, Ms. James and Mr. Jones were recommended by Mr. Flexon and reviewed and approved by the Compensation Committee. The award levels reflect the contributions each have made and Mr. Flexons
and the Compensation Committees desire to both retain each Named Executive Officer and ensure continued alignment with long-term stockholders interests. Mr. Flexons award was recommended
by the Compensation Committee and approved by the full Board. In determining the award level, the Compensation Committee took into account Mr. Flexons efforts and contributions in leading the Company, successful execution on critical
objectives and the importance of retaining him.

The table below illustrates the 2017 LTI award grant value for each of the Named Executive Officers.

Performance Share Units. The PSUs granted to our Named Executive Officers in 2017 may be earned over a three-year
performance period starting on January 1, 2017 based on our performance across two metrics, each weighted 50%: 1) our Total Shareholder Return (TSR) relative to a selected group of energy industry peer companies, and 2) cumulative Free Cash
Flow relative to pre-established goals. The Compensation Committee selected TSR as a performance measure because it aligns with the long-term interests of our
stockholders. The energy industry peer companies selected for TSR are the same as the companies disclosed under the prior Peer Group and Benchmarking section.Free Cash Flow was selected because it represents a critical
measure used by our stockholders to assess the strength of our business and success of our strategic efforts. The Compensation Committee set Free Cash Flow goals that were designed to be reasonably achievable but challenging. The number of PSUs
granted to each Named Executive Officer was based on the PSU Target Value shown above divided by the closing stock price of our common stock on the day of grant.

Set forth below are the key provisions of PSUs granted to our Named Executive Officers in 2017.

Restricted Stock Units. The number of RSUs granted to each Named Executive Officer was based on the RSU Value shown above
divided by the closing stock price of our common stock on the day of grant. Each RSU corresponds in value to a single share of our common stock. RSU awards will vest in three equal annual installments starting on the first anniversary of the
awards grant date. On each vesting date, the number of RSUs that vest will be settled and paid in a corresponding number of shares of our common stock.

Stock Options. The number of stock options granted to each Named Executive Officer was based on the Stock Option Value shown above divided by the Black
Scholes value of a single option determined on the day of grant. Stock options granted to each Named Executive Officer allows for the purchase of a fixed number of shares of our common stock at a fixed price (i.e., exercise price) over a ten-year period. The exercise price is set at the closing price of a share of our common stock on the date of grant. The stock options vest in three equal annual installments, on the anniversary date of the grant,
over the three-year vesting period.

Effect of Merger on Outstanding LTI Awards

Under the Merger Agreement, we agreed that at Merger Effective Time, each outstanding stock option would be converted into an option to purchase shares of Vistra Energy
Common Stock, on the same terms and conditions that were applicable under such stock options immediately prior to the effective time (including any accelerated vesting provisions), equal to the product of (A) the total number of shares of
Dynegy common stock subject to such stock option and (B) the Exchange Ratio, rounded down to the nearest whole number of shares of Vistra Energy Common Stock. The per-share exercise price of each
converted Vistra Energy option would be equal to the quotient determined by dividing (1) the exercise price per share applicable to the Dynegy option by (2) the Exchange Ratio, rounded up to the nearest whole cent.

At the Merger Effective Time, each outstanding RSU would be converted into a number of Vistra Energy restricted stock units equal to the product of (A) the number
of Dynegy RSUs held by such holder immediately prior to the effective time and (B) the Exchange Ratio, and remain outstanding on the same terms and conditions as were applicable to such award prior to the effective time (including any
accelerated vesting provisions).

At the Merger Effective Time, each outstanding PSU would be converted into the right to receive a number of shares of
Vistra Energy Common Stock (and cash in lieu of fractional shares to be paid by the surviving corporation to the holder) equal to the product of (A) the total number of shares of Dynegy common stock that would be payable in respect of such
Dynegy PSU (1) in the case of Dynegy PSUs granted in 2015, at the actual level of performance applicable to such Dynegy PSU as determined in accordance with the applicable award agreement and (2) in the case of Dynegy PSUs granted in 2016
and 2017, (x) at the actual level of performance applicable to such portion of such Dynegy PSU that relates to total stockholder return, as determined in accordance with the applicable award agreement, and (y) at the target level of performance
applicable to such portion of such Dynegy PSU that relates to free cash flow, and (B) the Exchange Ratio.

Additionally, on December 19, 2017, the Board
approved the acceleration of vesting of restricted stock units granted to Messrs. Flexon and Jones in 2015 that were otherwise scheduled to vest on March 3, 2018 and April 20, 2018 for Mr. Flexon and March 3, 2018 for
Mr. Jones. The Board approved the accelerated vesting of such grants, and the related withholding of shares to pay taxes, in order to mitigate potential adverse tax consequences of Section 280G of the Internal Revenue Code in connection
with the pending Merger.

Retirement Benefit Plans

Our Named
Executive Officers, similar to all employees, participate in our two qualified retirement plans: the Dynegy Inc. 401(k) Plan and the Dynegy Inc. Retirement Plan. The Dynegy 401(k) Plan provides for a dollar-for-dollar match for each dollar contributed (on a pre-tax basis) up to 5% of salary (with such elective contributions capped at $18,000 for 2017). Our matching
contributions to the Dynegy 401(k) Plan vest at a rate of 50% per year of service.

The Dynegy Inc. Retirement Plan provides a monthly benefit at retirement.
The amount of the retirement benefit is based, in part, on amounts contributed by the Company to each participants retirement account. The contribution rate is equal to 6% of a participants salary (with such salary capped at $265,000 for
plan purposes for 2017).

Our Named Executive Officers are all fully vested in the 401(k) and Retirement Plans and do not participate in any supplemental executive
retirement plans.

Executive Perquisites

For 2017, each Named
Executive Officer is eligible to receive an annual reimbursement for reasonable costs incurred for individual tax and financial planning advice up to $10,000. The total value of perquisites for each of our Named Executive Officers represents less
than 1% of their total compensation in 2017. On an annual basis, the Compensation Committee reviews executive perquisites.

Executive Agreements

Mr. Flexon was the sole Named Executive Officer who had an employment agreement with the Company which was amended to extend an additional term. The remaining
Named Executive Officers were covered under Executive Participation Agreements, which replaced these executive officers employment agreements. These agreements provided a specific level of participation under our executive Severance and Change
in Control Plans, which cannot be modified without consent from each individual Named Executive Officer.

Severance and Change in Control

We maintain a Severance Pay Plan under which specified payments and benefits would be provided to the Named Executive Officers in connection with a change in control.
The Severance Pay Plan provides for payment of certain severance benefits in the event of a termination. The change in control severance benefits for our Named Executive Officers include a double trigger provision required to receive any
severance payment. We believe these arrangements are important competitive benefits that assist in the attraction and retention of critical talent. Please read Executive CompensationPotential Payments Upon Termination or Change in
Control for further details on our Severance Pay Plan.

GOVERNANCE OF OUR EXECUTIVE COMPENSATION PRACTICES

Role of Compensation Committee

The Compensation Committee has overall
responsibility for reviewing and approving the principal terms of any employment, change of control, severance, or other like agreement between the Company and its executive officers. The Compensation Committee established the overall compensation
strategy and reviews such strategy at least annually for alignment with our business strategy and with similar programs offered by our competitors to ensure compensation arrangements are designed to provide incentives that are consistent with our
stakeholders of the Company but do not encourage senior executives to take excessive risks that threaten the value of the Company.

Role of Compensation
Consultant

As set forth in its charter, the Compensation Committee has the authority to retain or obtain the advice of a compensation consultant, and shall
be directly responsible for the appointment, compensation and oversight of the work of the consultant. Since 2012, the Compensation Committee has retained Meridian as its independent advisor. Meridian is an independent compensation consulting firm
and does not provide any other services to the Company outside of matters pertaining to executive and director compensation and related corporate governance matters. Meridian reports directly to the Compensation Committee, which is the sole party
responsible for determining the scope of services performed by Meridian, the directions given to Meridian regarding the performance of those services, and the approval of the payment of invoices for those services. The Compensation Committee
utilized Meridian in 2017 to provide information, analyses, and advice regarding executive compensation matters.

The Compensation Committee determined that the
services provided by Meridian to the Compensation Committee during 2017 did not give rise to any conflicts of interest. The Compensation Committee made this determination by assessing the independence of Meridian under the applicable rules adopted
by the SEC and incorporated into the NYSE Corporate Governance Listing Standards. In making this assessment, the Compensation Committee also considered Meridians written correspondence to the Compensation Committee that affirmed the
independence of Meridian and the partners, consultants and employees who provide services to the Compensation Committee on executive and director compensation matters.

Stock Ownership Guidelines

We have established Stock Ownership
Guidelines for officers to provide further alignment of interests among our executive officers and our stockholders. These guidelines are mandatory for all members of the executive management team and other officers. Executives are required to
achieve ownership levels within five years of hire or appointment. For those executives in place at bankruptcy emergence on October 1, 2012, the five year ramp up period was reset to the emergence date. Individuals holding the following titles
are included in this group: Chief Executive Officer and President, Executive Vice President, Senior Vice President and Vice President. The shares counted for purposes of the stock ownership guidelines include shares owned outright, unvested
restricted shares, vested stock options (in-the-money), and other share-based equivalents that may be used by Dynegy from time to
time. All officers, including our Named Executive officers are restricted from divesting any securities until their ownership multiples are attained, except to make a required tax payment, and must maintain their ownership level after any such
transaction. The table below sets forth the ownership levels set for our Named Executive Officers, expressed as a multiple of annual base salary.

Risk Assessment

The
Compensation Committee annually conducts an incentive risk assessment to ensure the structure and design of our Compensation programs are not reasonably likely to result in excessive risk taking that could have a material adverse impact on the
company.

Potential Impact of Restatements and Ability to Claw Back Compensation Awards

The Compensation Committee has a mechanism to address any restatements, if they occur, that may impact our key financial metrics and our financial performance. The
Compensation Committee will take action, as it determines to be appropriate, with respect to STI awards or other incentive or equity compensation awards to the extent such specified performance targets were not achieved in light of a restatement,
which could include seeking to recover amounts paid. We believe this mechanism allows for remedial action to be taken if executive compensation is awarded for achievement of financial performance that is later determined not to have been achieved
and further aligns our Named Executive Officers interests with those of our stockholders.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code imposes a $1 million limit on the amount that a publicly-traded corporation may deduct for compensation paid to
the Chief Executive Officer or one of the companys other three most highly compensated executives (other than the Chief Financial Officer) who is employed on the last day of the year. Performance-based compensation, as defined
under Internal Revenue Service rules and regulations, was excluded from this $1 million limitation. Our compensation programs are structured to support organizational goals and priorities and shareholder interests. In making compensation
decisions for 2017, the Compensation Committee considered the implications of Section 162(m) of the Internal Revenue Code.

The Tax Reform and Jobs Act of 2017
(the Act) eliminated the ability of companies to rely on the performance-based compensation exception under Section 162(m) and the $1 million limitation on deductibility generally was expanded to include all named
executive officers (including the principal financial officer). As a result, beginning in 2018, we will longer be able to take a deduction for any compensation paid to our named executive officers in excess of $1 million unless the compensation
originally qualified for the performance-based compensation exception and qualifies for transition relief applicable to certain arrangements in place on November 2, 2017. Despite the Compensation Committees efforts to
structure the executive compensation in a manner intended to be exempt from Section 162(m) and therefore not subject to its deduction limits, because of ambiguities and uncertainties as to the application and interpretation of
Section 162(m) and the regulations issued thereunder as amended by the Act, including the uncertain scope of the transition relief under the Act, no assurance can be given that compensation intended to satisfy the requirements for exemption
from Section 162(m) in fact will. Further, the Compensation Committee reserves the right to modify compensation that was initially intended to be exempt from Section 162(m) if it determines that such modifications are consistent with
Dynegys business needs.

In general, our philosophy is to seek to preserve the tax deductibility of executive compensation only to the extent practicable and
consistent with the overall compensation objectives discussed above. We do not make compensation determinations based on the accounting treatment of any particular type of award.

CEO PAY RATIO

We identified the median employee by examining 2017 W-2 wages obtained from internal payroll records for all employees,
excluding our CEO, who were employed by us on October 31, 2017. We included all employees, whether employed on a full-time or part-time basis. As of October 31, 2017 we analyzed 2,522 employees. We did not make any assumptions,
adjustments, or estimates with respect to the W-2 wages, and we did not annualize the compensation for any employees that were not employed by us for all of 2017. We believe the use of W-2 wages is the most appropriate compensation measure since it reflects actual wages.

After identifying the median employee based
on W-2 wages, we calculated annual 2017 compensation for the median employee using the same methodology used to calculate the chief executive officers total compensation as reflected in the Summary
Compensation Table below. The median employees annual 2017 compensation was as follows:



|                |  |      |      |  |        |  |          |       |  |  |             |  |  |                                      |        |  |                                                                     |  |        |                       |  |  |        |  |  |  |         |  |  |  |          |

The annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table below, was $8,569,751.

Our 2017 ratio of Chief Executive Officer total compensation to the median employees total compensation is reasonably estimated to be 58.62:1.

|(1) | Amounts include salary earned for a full 12 months. Actual salary earned in any calendar year may vary from the annual base salary due to timing of pay cycles and time of service.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | Represents additional discretionary amounts paid to the Named Executive Officers above amounts actually earned pursuant to the STI Plan.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------



|(3) | The amounts shown under Stock Awards for 2015, 2016 and 2017 reflect the aggregate grant date fair value for RSUs and PSUs (using the Monte Carlo valuation model) calculated in accordance with FASB ASC Topic
718. The amounts shown under Option/SAR Awards for 2015, 2016 and 2017 reflect the aggregate grant date fair value for options (using the Black Scholes valuation model) calculated in accordance with FASB ASC Topic 718. Please read the
discussion of the assumptions used in such valuation in Notes 15 and 17 of the Notes to Consolidated Financial Statements in our Original Form 10-K.

| | For 2015, RSUs and stock options have a three-year ratable vesting schedule, with 1/3 of each award vesting
each year beginning on March 3, 2016. For 2016, RSUs and stock options have a three-year ratable vesting schedule, with 1/3 of each
award vesting each year beginning on March 8, 2017. For 2017, RSUs and stock options have a three-year ratable vesting schedule, with
1/3 of each award vesting each year beginning on March 1, 2018. The PSUs for 2015, 2016 and 2017 require performance goals to be
attained over a three-year period following the granting of the opportunity for any actual award to be earned. For the grant date fair value of the PSUs, the value reported in the table is based on the probable outcome of the performance conditions
as of the grant date using the Monte Carlo valuation model. Based on the share price at grant and assuming the maximum market and financial performance conditions are achieved, the maximum value of the PSUs granted in fiscal year 2015, payable
following completion of the 2015-2017 performance period are: Mr. Flexon $3,752,038, Mr. Freeland $880,015, Ms. Burke $720,008, Ms. James $720,008 and Mr. Jones $720,008. The performance criteria for the 2015 PSUs were not
met resulting in no payment, thereby reducing the total value realization of the 2015 PSUs. For fiscal year 2016, payable following completion of the 2016-2018 performance period are: Mr. Flexon $4,360,021, Mr. Freeland $821,811,
Ms. Burke $742,008, Ms. James $735,002 and Mr. Jones $843,380. For fiscal year 2017, payable following completion of the 2017-2019 performance period are: Mr. Flexon $4,185,605, Mr. Freeland $720,004, Ms. Burke
$680,016, Ms. James $680,016 and Mr. Jones $720,004. Please read Compensation Discussion and AnalysisExecutive Compensation Program OverviewReported and Realizable Pay above for further discussion of value
realization of LTI awards.

|(4) | The amounts shown under Non-Equity Incentive Plan Compensation for 2015, 2016 and 2017 reflect cash bonuses awarded under the STI Plan. The 2015 incentive payments
were earned in 2015 and paid in March 2016, the 2016 incentive payments were earned in 2016 and paid in March 2017 and the 2017 incentive payments were earned in 2017 and were partially paid in December 2017 and March 2018. To mitigate the potential
impact of Section 280G with respect to the pending Merger on Dynegy and the named executive officers, on December 19, 2017, the Board approved payment during 2017 of 75% of the annual bonus that it expected it would have otherwise paid to
each respective named executive officer in early 2018.

|(2) | In March 2017, PSUs were granted under the Dynegy Inc. Amended and Restated 2012 Long Term Incentive Plan, or 2012 Long Term Incentive Plan. The PSUs require performance goals to be attained over a three-year period,
subject to certain exceptions, upon the granting of the opportunity for any actual award to be earned. For the grant date fair value of the PSUs, the value reported in the table is based on the probable outcome of the performance conditions as of
the grant date, March 1, 2017, using the Monte Carlo valuation model.

OUTSTANDING EQUITY AWARDS AT 2017 FISCAL YEAR-END

Upon our emergence from bankruptcy in 2012 and pursuant to the plan of reorganization, all outstanding equity awards of the Company as of the effective date were
cancelled. The following table sets forth certain information regarding unexercised option awards and unvested stock awards granted to each Named Executive Officer following emergence from bankruptcy that were outstanding as of December 31,
2017. The table does not include information regarding equity based awards related to 2017 performance that were or may be granted to the Named Executive Officers in 2018. The vesting schedules for each type of award are described in the footnotes
to the table, and the vesting date for each award can be determined by referring to the grant date for each award in the table.

|(3) | The market value of the RSUs and PSUs (at target level) is based on the closing market price of our common stock on December 29, 2017 of $11.85. The performance criteria for the 2015 PSUs were not met
resulting in no payment, thereby reducing the total value realization of the 2015 PSUs. Please read Compensation Discussion and AnalysisExecutive Compensation Program OverviewReported and Realizable Pay above for further
discussion of value realization of LTI awards.

|(4) | The PSUs require performance goals to be attained over a three-year period, subject to certain exceptions, upon the granting of the opportunity for any actual award to be earned. The PSUs are payable, if performance
criteria are met, in common stock.

|(1) | Dynegys allocations to the Retirement Plan for the PRB component of that plan vest at a rate of 33%, 67% and 100% after completion of each year of service over three years. Our allocations to the Restoration
Pension Plan vested at the same rate as under the PRB component of the Retirement Plan. Effective January 1, 2012, participation in the Restoration Pension Plan was frozen, and benefit accruals were suspended.

Our Named Executive Officers are eligible for qualified pension benefits under the Retirement Plan. The pension benefit is based on the PRB portion of the Retirement
Plan, which provides a defined benefit that grows each year at a variable rate (30-year Treasury rate). This benefit, which was introduced in 2001, provides an annual contribution of 6% of each eligible
employees salary, including each Named Executive Officers salary, capped at $270,000 for 2017. Our Named Executive Officers were eligible in 2011 to participate in the Restoration Pension Plan, which is an unfunded, nonqualified plan
designed to provide an allocation or benefit to certain employees that are highly compensated and whose company pension contributions are limited under certain Internal Revenue Service, or IRS, requirements for qualified plans. Under the Restoration
Pension Plan the allocations or benefits were intended to supplement or make up for what affected employees would have received under the Retirement Plan but for the IRS limitations. The participation in the Restoration Pension plan was frozen,
effective for periods on and after January 1, 2012, and benefit accruals have also been suspended.

The present values of accumulated benefits payable to each of the Named Executive Officers under the Retirement Plan and
Restoration Pension Plan were determined using assumptions consistent with those used in Note 17 of the Notes to Consolidated Financial Statements in our Original Form 10-K.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

We have entered
into certain agreements and maintain certain plans, as described below, which require us to provide specified payments and benefits to our Named Executive Officers as a result of severance eligible events, a change in control, retirement, death, and
disability.

In connection with the Merger, certain executive officers of Dynegy (including its current named executive officers) may become entitled to payments
and benefits that may be treated as excess parachute payments within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (Section 280G). To mitigate the potential impact of Section 280G
on Dynegy and the named executive officers, on December 19, 2017, Dynegys Board of Directors approved (i) payment during 2017 of 75% of the annual bonus that it presently expects would otherwise be paid to each respective named
executive officer in early 2018 and (ii) the immediate vesting and settlement of 173,650 restricted stock units previously granted to Mr. Flexon and 3,854 restricted stock units previously granted to Mr. Jones. Those restricted stock
units were granted in 2015 and were otherwise scheduled to vest, in the case of Mr. Flexon, on March 3, 2018 and April 20, 2018, and, in the case of Mr. Jones, on March 3, 2018.

Also, on December 19, 2017, Dynegy entered into an acknowledgment (the Acknowledgment) with the named executive officers. Each named executive officer agreed
to repay the accelerated annual bonus payment amounts to the extent it was subsequently determined that the right to payment would have been forfeited before payment otherwise would have been made in the ordinary course.

CompensationEffect of Merger on Outstanding LTI Awards

Employment Agreement

Robert Flexon. Mr. Flexons employment agreement commenced on July 11, 2011 and on May 6, 2015 was amended and restated through
April 30, 2018. Under the amended and restated agreement, Mr. Flexons base salary was initially set at $1,100,000, subject to review by the Board from time to time for increases. He participates in our STI Plan with a current target
award of 125%, of his base salary subject to review by the Board from time to time for increases. In connection with execution of the amended and restated agreement, Mr. Flexon received a restricted stock unit award grant on May 11, 2015
with a grant date value of $5,000,000, which, as stated above, vested on December 19, 2017. On October 29, 2017, the board of directors of Dynegy approved and entered into an amendment to the Amended and Restated Employment
Agreement. The amendment extended the term of Mr. Flexons employment agreement for an additional term, which shall commence on May 1, 2018 and conclude on April 30, 2019.

Furthermore, Mr. Flexon is eligible to receive additional annual award grants pursuant to our LTI programs and he participates in our other employee benefit plans
and programs, including severance benefits described below. If Mr. Flexon is terminated for any reason as described in his employment agreement, we are obligated to pay or provide to Mr. Flexon (or his estate, if applicable) in a lump sum
within 30 days following such termination, or at such other time prescribed by any applicable plan: (1) any base salary payable to him pursuant to the agreement, accrued up to and including the date on which Mr. Flexons
employment terminates; (2) any employee benefits to which he is entitled upon termination of his employment in accordance with the terms and conditions of the applicable plans; (3) reimbursement for any unreimbursed business expenses
incurred prior to his date of termination; and (4) payment for accrued but unused vacation time as of the date of his termination, in accordance with our policies.

In connection with the consummation of the Merger, Mr. Flexon received the amounts to which he was entitled pursuant to his employment agreement as described
above.

Participation Agreements

On October 28, 2015, the EVPs entered into Participation Agreements. Simultaneous with the commencement of the Participation Agreements all existing EVP employment
agreements, including the Named Executive Officers agreements, were terminated. The Participation Agreements provide for guaranteed participation rights and protections in certain compensation and benefits plans, including our LTI programs and
the Severance Pay Plan.

Voluntary Resignation and Termination for Cause

Except as otherwise described under Severance Eligible Terminations and Change in Control, our Named Executive Officers are not entitled to
payments or benefits in connection with a voluntary resignation or termination for cause, other than payments for amounts due before such termination. Under our company policy applicable to all employees, a Named Executive Officer terminated under
such circumstances would be entitled to vacation pay accrued up to the month of termination. A Named Executive Officer would be able to exercise any options vested before the date of termination upon termination for cause and for a 90-day period after the date of termination upon a voluntary resignation, or through the end of the option term, if less. Vested options that were not exercised before the date of termination, in the case of
termination for cause, or before the end of the 90-day period, or end of the option term if less, in the case of voluntary resignation, unvested options, RSUs and PSUs would all be forfeited as a result of
termination in accordance with the applicable award agreement.

Severance Eligible Terminations

Any outstanding stock options, RSUs, phantom stock units, PSUs and other equity based awards previously granted to our executives will vest based upon the applicable LTI
award agreement.

In addition, pursuant to our Severance Pay Plan, our executives are entitled to payment of severance benefits if their employment is terminated
due to an involuntary termination without cause or upon a good reason termination. A good reason termination is defined as a voluntary resignation following a material reduction in the nature or scope of the executives authority or
duties, a material diminution in the executives base salary or STI target, or a change in the location of the executives principal place of employment by 50 miles or more. Severance benefits for executives under the Severance Pay Plan,
which are payable in a lump sum, include:



| |  | for the Chief Executive Officer and Executive Vice President, 200% of compensation (defined as base salary plus target bonus);
|- |  | ------------------------------------------------------------------------------------------------------------------------------



| |  | for any Senior Vice President or Vice President, 100% of compensation (defined as base salary plus target bonus);
|- |  | -----------------------------------------------------------------------------------------------------------------



| |  | the executive shall be eligible to receive a pro-rata bonus payment (determined by actual performance of the Company), which shall be paid at the same time as STI payments are
made if the executives termination occurs on or after July 1. In addition, the executive shall be eligible to receive any STI payment for the prior year that has not been paid as of the termination date;
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | continued participation in our group health care plan that provides medical and dental for 24 months for a Chief Executive Officer and Executive Vice President and 12 months for a Senior Vice President and
Vice President, provided the executive continues to pay premiums at active employee rates, with such coverage ending immediately upon the executive obtaining new employment and eligibility for similar coverage;
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | benefits resulting from a change of control would be cut back if doing so would result in greater after-tax proceeds to an executive absent such cut back Best Net
provision. Otherwise, the executive would receive payment of all change of control related benefits and would be responsible for paying any excise tax incurred under Internal Revenue Code section 280(G); and
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | outplacement assistance benefits, as determined by the plan administrator, for a period of time equal to the minimum number of months of base pay such executive is entitled to receive under the Executive Severance Pay
Plan (but in any event not beyond the end of the second calendar year following the calendar year in which the executive terminated employment), with such benefits paid directly to the outplacement assistance provider and not to the executive in a
lump sum.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The foregoing benefits may be subject to the following material conditions or obligations:



| |  | non-competition, non-disclosure, non-disparagement, and
non-solicitation requirements; and
|- |  | ------------------------------------------------------------------------------------------



| |  | execution and performance of a release and waiver of liability agreement with respect to his or her employment and termination.
|- |  | -------------------------------------------------------------------------------------------------------------------------------

Change in Control

In the event of a change in control or Corporate
Change, the RSUs and option awards granted under the 2012 Long Term Incentive Plan require a double trigger, both the occurrence of a Corporate Change and an involuntary termination, to vest. For PSUs, upon a Corporate Change, the Named Executive
Officers would be entitled to receive payment as prescribed by the award agreement regardless of whether the Named Executive Officer is terminated.

In addition,
each of our executives is entitled to severance benefits if, no earlier than 60 days before and in connection with or within two years after a change in control, such executive is subject to an involuntary termination or termination for good
reason, as defined in the Severance Pay Plan. A good reason termination is defined as a voluntary resignation following a material reduction in the nature or scope of the executives authority or duties, a material diminution in the
executives base salary or STI target, or a change in the location of the executives principal place of employment by 50 miles or more.

|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | outplacement assistance benefits at least equivalent to those that would have been provided to the Named Executive Officer before the change in control (but in any event not beyond the end of the second calendar year
following the calendar year in which the executive terminated employment), with such benefits paid directly to the outplacement assistance provider and not to the executive in a lump sum.
|- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|- |  | -------------------------------------------------------------------------------------------------------------------------------

Retirement

As of December 31, 2017, none of our Named Executive
Officers have reached eligibility age for payments upon retirement.

Disability or Death

All of our employees may elect to participate in our disability policy, and any participating employee would be entitled to long-term disability benefits under such
disability policy if he or she paid any required premiums. All of our Named Executive Officers have elected to participate in our disability policy. Under such policy, all employees at the level of Vice President or above are entitled to
12 months of the monthly base salary that is in effect on the date that the employee is determined to be disabled. Additionally, employees at the level of Vice President or above are also provided with additional basic life insurance coverage
as supplemental life insurance equal to 12 months of monthly base salary.

Further, in the event of death, the medical, dental and vision benefits that we
maintained for the deceased employee at the level of Vice President or above and his or her family would be maintained for 12 months after the date of death, provided that such employees covered dependents continue to pay the required
premiums. Such employees Dynegy 401(k) Plan distributions and Retirement Plan benefits would generally be paid to his or her beneficiary. Health benefits in the event of disability vary depending on the type of disability.

In addition, each Named Executive Officers equity based awards would vest upon death or disability in accordance with the applicable LTI award agreement.

Potential Payments and Benefits

The following tables describe the estimated potential payments we would have been required to make to our Named Executive Officers under the severance and change in
control plans, as applicable, upon termination of their employment under various circumstances. The following assumptions and general principles apply with respect to these tables:



| |  | The amounts shown assume the applicable termination event took place on December 29, 2017, the last business day of the year; accordingly, values associated with LTI awards made in March 2018 are not included;
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The price per share used to calculate the value of the equity based payments is the closing price of our common stock on December 29, 2017 of $11.85;
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The amounts shown as Base salary under the Severance Eligible Termination and Change in Control columns are the lump sum cash payments described above as compensation under
Severance Eligible and Change in Control, respectively;
|- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The amounts shown as Short-term Incentive Bonus under the Severance Eligible Termination and Change in Control columns are calculated based upon achieving target; however, actual
results could differ based upon Company performance;
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The amounts shown for Medical, dental and vision benefits under the Severance eligible terminations column assume that the applicable Named Executive Officer continued to participate in our group
health care for the maximum period of time permitted for such Named Executive Officer under the Executive Severance Pay Plan; and
|- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | The amounts shown for Accidental death & dismemberment insurance proceeds under the Disability column represent the maximum payment available under the applicable accidental death and
disability policy. The actual value could be lower depending on the type of disability. Under the Death column is the maximum payment if death occurred from an accident covered under the applicable accidental death and disability policy.

|(1) | The Named Executive Officers would be able to exercise any options vested before the day of termination for cause or for a 30-day period after the date of termination upon a
voluntary resignation, or through the end of the option term, if less. If Mr. Flexons Employment Agreement, as amended, terminates according to its terms, Mr. Flexon would be able to exercise any options within 10 years from the
effective date of the option.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | The Named Executive Officers are eligible to participate in the Severance Pay Plan. Under the Severance Pay Plan, in the event an Involuntary Termination occurs each is eligible to receive 200% his or her compensation
(annual base salary plus target STI award). The executives shall also be eligible to receive a pro-rata bonus payment (determined by actual performance of the Company), which shall be paid at the same time as
STI payments are made if the executives termination occurs on or after July 1. The Severance Pay Plan also provides for medical, dental, and vision benefits at the active employee rates for 24 months. Under the Change in Control provision of the
Severance Pay Plan, in the event of an Involuntary Termination, Mr. Flexon is eligible to receive a severance payment equal to 299% his compensation (annual base salary plus target STI award), a pro-rata
bonus payment (determined by actual performance of the Company), which shall be paid at the same time as STI payments are made, 36 months of medical, dental, and vision benefits coverage at the active employee rates. Messrs. Freeland and Jones and
Mses. Burke and James are eligible to receive a severance payment equal to 250% their compensation (annual base salary plus target STI award), a pro-rata bonus payment (determined by actual performance of the
Company), which shall be paid at the same time as STI payments are made, and 30 months of medical, dental, and vision benefits coverage at the active employee rates. In the event of a change in control and subsequent Involuntary Termination, the
Named Executive Officers will also have accelerated vesting treatment on the Incremental non-qualified pension. Outplacement services are made available under both plans for all eligible employees.

|(3) | Under the PSU award agreements granted in 2015, the Named Executive Officers would be entitled to a pro-rata vesting of the PSUs at the target level of the award for
an involuntary termination without cause. Under the PSU award agreements granted in 2016 and 2017, the Named Executive Officers would be entitled to, upon an involuntary termination without cause, vesting of the PSUs upon completion of the
performance period based solely upon the actual level of performance of the Company. Upon a Corporate Change for awards issued in 2015, 2016 and 2017, each Named Executive Officer would be entitled to receive payment as prescribed by the award
agreement regardless of whether he or she is terminated. For purposes of this table, the value for a corporate change was calculated using the target level.

Item 12.Security Ownership of Certain Beneficial Owners and Management
and Related Stockholder Matters

SECURITY OWNERSHIP OF CERTAIN
BENEFICIAL OWNERS AND MANAGEMENT

On the Closing Date, the Company merged with and into
Vistra Energy, with Vistra Energy continuing as the surviving corporation. At the Merger Effective Time, each issued and outstanding share of Dynegy Common Stock (other than shares owned by Vistra Energy or its wholly owned subsidiaries, held in
treasury by the Company or held by a wholly owned subsidiary of the Company, which shares were automatically cancelled and ceased to exist) was automatically converted into the right to receive 0.652 shares of Vistra Energy Common Stock.

As of the Merger Effective Time, each outstanding Dynegy stock option was automatically converted into an option to purchase shares of Vistra Energy Common Stock, on
the same terms and conditions that were applicable under such Dynegy stock option immediately prior to the Merger Effective Time (including any accelerated vesting provisions), equal to the product of (A) the total number of shares of Dynegy
Common Stock subject to such Dynegy stock option and (B) the Exchange Ratio, rounded down to the nearest whole number of shares of Vistra Energy Common Stock. The per-share exercise price of each
converted Vistra Energy stock option is equal to the quotient determined by dividing (1) the exercise price per share applicable to the Dynegy stock option by (2) the Exchange Ratio, rounded up to the nearest whole cent.

As of the Merger Effective Time, each outstanding award of restricted stock units with respect to shares of Dynegy Common Stock other than Dynegy phantom stock units
(Dynegy RSUs) was automatically converted into a number of restricted stock units with respect to shares of Vistra Energy Common Stock (Vistra RSUs) equal to the product of (A) the number of Dynegy RSUs held by such
holder immediately prior to the Merger Effective Time and (B) the Exchange Ratio, and remains outstanding on the same terms and conditions as were applicable to such award prior to the Merger Effective Time (including any accelerated vesting
provisions).

As of the Merger Effective Time, each outstanding Dynegy performance stock unit (a Dynegy PSU) was automatically converted into the right
to receive from Vistra Energy, at the Merger Effective Time, a number of shares of Vistra Energy Common Stock (and cash in lieu of fractional shares to be paid by the surviving corporation to the holder) equal to the product of (A) the total
number of shares of Dynegy Common Stock that would be payable in respect of such Dynegy PSU (1) in the case of Dynegy PSUs with respect to which the Merger Effective Time occurred after the first twelve months of the applicable performance
period, (x) at the actual level of performance applicable to such portion of such Dynegy PSU that relates to total stockholder return, as determined in accordance with the applicable award agreement, and (y) at the target level of
performance applicable to such portion of such Dynegy PSU that relates to free cash flow, and (2) in the case of Dynegy PSUs with respect to which the Merger Effective Time occurred within the first twelve months of the applicable performance
period, (x) at the target level of performance applicable to such portion of such Dynegy PSU that relates to total stockholder return, as determined in accordance with the applicable award agreement, and (y) at the target level of
performance applicable to such portion of such Dynegy PSU that relates to free cash flow, and (B) the Exchange Ratio.

As of the Merger Effective Time, each
outstanding Dynegy phantom stock unit was automatically converted into phantom stock units relating to the number of shares of Vistra Energy Common Stock equal to the product of (A) one share of Dynegy Common Stock and (B) the Exchange
Ratio, and remains outstanding on the same terms and conditions as were applicable to such award immediately prior to the Merger Effective Time.

As of the Merger
Effective Time, the number of hypothetical shares of Dynegy Common Stock credited to the company deferral account of each participant in Dynegys deferred compensation plan which company deferral account had an outstanding balance as of
immediately prior to the Merger Effective Time was automatically converted into that number of hypothetical shares of Vistra Energy Common Stock equal to the product of (A) the total number of hypothetical shares of Dynegy Common Stock credited
to such company deferral account and (B) the Exchange Ratio, and such company deferral account has the same terms and conditions as were applicable to such company deferral account immediately prior to the Merger Effective Time.

As a result of the Merger, none of the companys directors or executive officers, nor any other person, held shares of
Dynegy Common Stock as of April 26, 2018 or had the right to acquire shares of Dynegy Common Stock within 60 days of April 
26, 2018.

Item 13.Certain Relationships and Related Transactions, and Director
Independence

REVIEW AND APPROVAL OF TRANSACTIONS WITH RELATED PERSONS

Our Board adopted a written policy relating to the approval of transactions with related parties. In general, for purposes of this policy, a related party transaction
is a transaction to which we are a party, or a material amendment to any such transaction, and with respect to which a related party is directly, or to our knowledge, indirectly, a party. Under our policy, a related party is an executive
officer, director or nominee for director of ours, a person known to us to be the beneficial owner of more than 5% of our voting securities, an immediate family member of an executive officer, director, nominee for director or 5% stockholder, and
any entity owned or controlled by any of the foregoing individuals or in which any such individual serves as an executive officer or general partner or, together with any other such individuals, owns 10% or more of the equity interests of such an
entity. Our policy requires the Audit Committee or, at the Boards discretion, a majority of directors disinterested from the transaction, to review and approve related party transactions. In reviewing and approving any related party
transaction or material amendments to any such transaction, the Audit Committee must satisfy itself that it has been fully informed as to the related partys relationship and interest and as to the material facts of the transaction and must
determine that the related party transaction is fair to us.

A copy of our related party transactions policy is available on our web site at https://www.dynegy.com/investors/leadership-governance/corporate-governance/governance-documents.

AFFIRMATIVE DETERMINATIONS REGARDING DIRECTOR INDEPENDENCE AND OTHER MATTERS

The Board previously determined that each of the following directors who served in 2017 is independent as such term is defined in the NYSE Listed Company
Standards:

Pat Wood III

Hilary E. Ackermann

Paul M. Barbas

Richard L. Kuersteiner

Jeffrey S. Stein

John R. Sult

The Board has also determined that each member of the Audit Committee, the Compensation and Human Resources Committee, or Compensation Committee, and the Nominating
Committee meets the independence requirements applicable to those committees prescribed by the NYSE and the SEC. The Board has further determined that more than one of the members of the Audit Committee, including its current Chairman,
Mr. Sult, are audit committee financial experts as such term is defined in Item 407(d) of the SECs Regulation S-K.

The Nominating Committee reviewed the answers to annual questionnaires completed by the directors and nominees as well as the above described legal standards for Board
and committee member independence and the criteria applied to determine audit committee financial expert status. On the basis of this review, the Nominating Committee made its recommendation to the full Board and the Board made its
independence and audit committee financial expert determinations after consideration of the Nominating Committees recommendation and a review of the materials made available to the Nominating Committee.

Item 14.Principal Accountant Fees and
Services

PRINCIPAL ACCOUNTING FEES AND SERVICES

Ernst & Young LLP (EY) served as our independent registered public accountants for the years ending December 31, 2017 and 2016. Set forth
below is a summary of the fees we paid EY for professional services rendered for the years ended December 31, 2017 and 2016.



|                      |  |  |  |  |        |  |  |  |        | 
|--------------------- |  |  |  |  | ------ |  |  |  | ------ | 
|(in
thousands)        |  |  |  |  | 2017   |  |  |  | 2016   | 
|Audit Fees(1)         |  |  |  |  | $4,929 |  |  |  | $4,110 | 
|Audit Related Fees(2) |  |  |  |  | 578    |  |  |  | 320    |

|Total Fees            |  |  |  |  | $5,600 |  |  |  | $4,484 | 



|(1) | Audit fees relate to the audit of Dynegys financial statements and the effectiveness of our internal control over financial reporting for the years ended December 31, 2017 and 2016. Audit Fees increased in
2017 primarily due to costs associated with the purchase accounting of the Engie acquisition in 2017, as well as the implementation of the new Revenue Accounting Standards.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | Audit related fees include fees of $10,000 and $0 in 2017 and 2016, respectively, for the audits of separate financial statements of certain of our consolidated subsidiaries and/or equity method investments.
Additionally, 2017 and 2016 fees included $568,000 and $320,000, respectively, for services rendered related to Dynegy Inc. registration statements.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Tax fees include fees of $93,000 and $54,000 in 2017 and 2016, respectively, related to advisory services for federal and state tax returns.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------

All of the fees and services described above under the captions Audit Fees, Audit Related Fees, Tax Fees and All Other
Fees were approved under the Audit Committees pre-approval policy and pursuant to Section 202 of SOX. None of the services described above were provided pursuant to the de minimus exception
provided for in applicable SEC rules and regulations.

AUDIT COMMITTEE PRE-APPROVAL POLICY

The Audit Committee is responsible for appointing, setting compensation for and overseeing the work of our independent registered public accountants. The Audit
Committee has established a policy requiring its pre-approval of all audit and permissible non-audit services to be provided by our independent registered public
accountants in order to assure that the provision of such services does not impair the auditors independence. The policy, as amended, provides for the general pre-approval of specific types of services,
gives detailed guidance to management as to the specific audit, audit related and tax services that are eligible for general pre-approval and provides specific fee limits for each such service type on an
annual basis. The policy requires specific pre-approval of the annual audit engagement, statutory or subsidiary audits and all permissible non-audit services for which
no general pre-approval exists. For both audit and non-audit pre- approvals, the Audit Committee considers whether such services
are consistent with applicable law and SEC rules and regulations concerning auditor independence.

The Audit Committee Charter provides that the Audit Committee may
delegate to the Audit Committee Chairman the authority to grant pre-approvals only if such approvals are presented to the Audit Committee at a subsequent meeting. The policy prohibits the Audit Committee from
delegating to management such committees responsibility to pre-approve services performed by the independent registered public accountants. When we engage the independent registered public accountants to
perform services based on a general pre- approval, our Chief Financial Officer or, in his absence, our Chief Accounting Officer is required to, as soon thereafter as reasonably practicable, notify the chairman
of such engagement and provide a detailed description of the type and scope of services, proposed staffing, a budget of the proposed fees for such services and a general timetable for the performance of such services.

Requests for pre-approval of services must be detailed as to the particular services proposed to be provided and are to be
submitted by our Chief Financial Officer or, in his or her absence, our Chief Accounting Officer. Generally, each such request must include a joint statement to the effect that neither the submitting officer nor the

independent registered public accountants believe the proposed engagement would impair the auditors independence. In addition, each such request generally must include a detailed
description of the type and scope of services, proposed staffing, a budget of the proposed fees for such services and a general timetable for the performance of such services.
