Only persons who were stockholders of record at the close of business on March 31, 2014 are entitled to notice of, and to vote at, the Annual Meeting.

Voting in advance of the meeting will not deprive you of your right to participate in the virtual meeting and to vote your shares during the live webcast if you so choose.

Sincerely,

Pat Wood III
Chairman of the Board

PROXY STATEMENT

GENERAL INFORMATION

Why am I receiving these materials?

        The Board of Directors of Dynegy Inc., or the Board, has made these materials available to you over the internet, or has delivered printed versions of these materials to you by mail, in connection with the Board's solicitation of proxies for use at the 2014 Annual Meeting of Stockholders, or the Annual Meeting. The Annual Meeting is scheduled to be held on Thursday, May 29, 2014 at 10:00 a.m., Central Time, via live webcast through the link www.virtualshareholdermeeting.com/DYN14. You will need the 12-digit control number provided on the Notice of Internet Availability of Proxy Materials or your proxy card (if applicable). This solicitation is for proxies for use at the Annual Meeting or at any reconvened meeting after an adjournment or postponement of the Annual Meeting.

What is included with these materials?

        These materials include our proxy statement for the Annual Meeting and our 2013 Annual Report to Stockholders, or Annual Report, which includes our audited consolidated financial statements. If you received printed versions of these materials, a proxy card for the Annual Meeting is also included.

What items will be voted on at the Annual Meeting?

        There are three items that will be voted on at the Annual Meeting:

1.

The election of seven directors to serve until the 2015 Annual Meeting of Stockholders;



2.

A proposal to approve, on an advisory basis, the compensation of Dynegy's named executive officers as described in this proxy statement; and



3.

A proposal to ratify the appointment of Ernst & Young LLP as Dynegy's independent registered public accountants for the fiscal year ending December 31, 2014.

        Additionally, if needed, the stockholders may act upon any other matters that may properly come before the meeting (including a proposal to adjourn the meeting to solicit additional proxies) or any reconvened meeting after an adjournment or postponement of the meeting.

What are the Board's voting recommendations?

        The persons named as proxies were designated by the Board. Any proxy given pursuant to this solicitation and received prior to the Annual Meeting will be voted as specified in the proxy card. If you return a properly executed proxy card but do not mark any voting selections, then your proxy will be voted as follows in accordance with the recommendations of the Board:

•

Proposal 1—FOR the election of the seven director nominees to the Board;



•

Proposal 2—FOR approval of the compensation of Dynegy's named executive officers described in this proxy statement; and

1

---

•

Proposal 3—FOR ratification of the appointment of Ernst & Young LLP as our independent registered public accountants.

Why did I receive a one-page notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

        Pursuant to the rules adopted by the Securities and Exchange Commission, or SEC, we are providing electronic access to our proxy materials over the internet. Accordingly, we sent a Notice of Internet Availability of Proxy Materials, or Notice, to our stockholders of record and beneficial owners, which was first mailed on or about April 11, 2014. Instructions on how to access the proxy materials over the internet are included in the Notice.

        Stockholders may also request via the internet to receive a printed set of the proxy materials at www.proxyvote.com, by sending an email to sendmaterial@proxyvote.com, or calling 1-800-579-1639. In addition, stockholders may request via the internet, telephone or by email to receive proxy materials in printed form on an ongoing basis.

        Current and prospective investors can also access or order free copies of our Annual Report, proxy statement, Notice and other financial information through the Investor Relations section of our web site at www.dynegy.com, by calling 713-507-6400 or by writing to Investor Relations Department, Dynegy Inc., 601 Travis, Suite 1400, Houston, Texas 77002.

How can I get electronic access to the proxy materials?

        The Notice provides you with instructions regarding how to:

•

View proxy materials for the Annual Meeting on the internet; and



•

Instruct us to send our future proxy materials to you electronically by email.

        Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you and will reduce the impact of our Annual Meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it. Internet/telephone voting for the Annual Meeting will close at 11:59 p.m., Eastern Time, on May 28, 2014.

Why did I only receive one set of materials when there is more than one stockholder at my address?

        If two or more stockholders share one address, each such stockholder may not receive a separate copy of our Annual Report, proxy statement or Notice. Stockholders who do not receive a separate copy of our Annual Report, proxy statement or Notice and want to receive a separate copy may request to receive a separate copy of, or additional copies of, our Annual Report, proxy statement or Notice via the internet, email or telephone as outlined above. Stockholders who share an address and receive multiple copies of our Annual Report, proxy statement or Notice may also request to receive a single copy by following the instructions above.

What is the quorum requirement for the Annual Meeting?

        With respect to each matter to be considered at the Annual Meeting, a majority of the outstanding shares of our common stock entitled to vote on each such matter, represented in person (through internet access) or by proxy, shall constitute a quorum for consideration of each such matter. Abstentions and broker non-votes shall be counted in determining the number of outstanding shares represented in person (through internet access) or by proxy for each matter.

Where is the Annual Meeting?

        You are invited to attend the Annual Meeting online through the link www.virtualshareholdermeeting.com/DYN14. The 12-digit Control Number provided on your Notice or proxy card is necessary to access this site.

        As of the record date, March 31, 2014, there were outstanding 100,312,835 shares of common stock.

What is the difference between holding shares as a stockholder of record and as a beneficial owner of shares held in street name?

        Stockholder of Record.    If your shares are registered in your name with our transfer agent, Computershare, you are considered the stockholder of record with respect to those shares, and the Notice was sent directly to you by us.

        Beneficial Owner of Shares Held in Street Name.    If your shares are held in an account at a brokerage firm, bank, broker dealer or other similar organization, then you are the beneficial owner of shares held in "street name," and the Notice was forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.

If I am a stockholder of record of Dynegy's shares, how do I vote?

        If you are a stockholder of record you may vote by proxy over the internet by following the instructions provided in the Notice, by telephone, or, if you received printed copies of the proxy materials, you may also vote by mail. You may also vote at the Annual Meeting through the link www.virtualshareholdermeeting.com/DYN14. The 12-digit Control Number provided on your Notice or proxy card is necessary to access this site. Please vote as soon as possible.

If I am a beneficial owner of shares held in street name, how do I vote?

        If you are a beneficial owner of shares held in street name, please refer to the Notice, proxy card, or voting information form forwarded to you by your broker or other nominee to see what voting options are available to you. Please vote as soon as possible.

What happens if I do not give specific voting instructions?

        Stockholder of Record.    If you are a stockholder of record and you:

•

indicate when voting on the internet or by telephone that you wish to vote as recommended by our Board; or



•

if you sign and return a proxy card without giving specific voting instructions,

then the proxy holders will vote your shares in the manner recommended by our Board on Proposals 1-3 in this proxy statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting.

        Beneficial Owner of Shares Held in Street Name; "Broker Non-Votes."    If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, under the rules of the New York Stock Exchange, or NYSE, the organization that holds your shares may generally vote on routine matters but cannot vote on non-routine matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the organization that holds your shares will inform our Inspector of Election that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to

3

---

as a "broker non-vote." When our Inspector of Election tabulates the votes for any particular matter, broker non-votes will be counted for purposes of determining whether a quorum is present for that matter, but will not otherwise be counted. For example, please note that brokers may not vote your shares on the election of directors or the proposal regarding named executive officer compensation in the absence of your specific instructions as to how to vote. Please provide your broker with voting instructions as soon as possible so that your vote can be counted. We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided in the Notice.

Which ballot measures are considered "routine" or "non-routine"?

        Proposal 3 (Ratification of Appointment of Independent Registered Public Accountants) involves a matter that we believe will be considered routine.

        Proposal 1 (Election of Directors) and Proposal 2 (Approval of Compensation of our Named Executive Officers) involve matters that we believe will be considered non-routine.

How are abstentions and broker non-votes treated?

        For the purpose of determining whether a quorum is present, abstentions and broker non-votes shall be counted in determining the number of outstanding shares represented in person (through internet access) or by proxy for each matter.

        For each "non-routine" proposal, including whether the stockholders have elected the seven director nominees, broker non-votes are not counted. Please note that brokers may not vote your shares on the election of directors or the proposal regarding named executive officer compensation in the absence of your specific instructions as to how to vote. Please provide your broker with voting instructions as soon as possible so that your vote can be counted. You cannot abstain in the election of directors—you can only vote FOR the director nominees or WITHHOLD VOTES for such nominees.

        For each proposal other than the election of directors an abstention will have the same effect as a vote AGAINST such proposal.

What is the voting requirement to approve each of the proposals?

        The following table sets forth the voting requirement with respect to each of the proposals:

May I change my vote after I have voted?

        You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting by:

•

Executing and submitting a revised proxy (including a telephone or internet vote, which must be received by 11:59 p.m., Eastern Time, on May 28, 2014);



•

Sending written notice of revocation to our Corporate Secretary at the address provided below (which must be received by 11:59 p.m., Eastern Time, on May 28, 2014); or

        In the absence of a revocation, shares represented by proxies will be voted at the Annual Meeting.

Is my vote confidential?

        Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within Dynegy or to third parties, except:

•

As necessary to meet applicable legal requirements;



•

To allow for the tabulation and certification of votes; and



•

To facilitate a proxy solicitation.

Who is paying the cost of this proxy solicitation?

        We will bear the cost of soliciting proxies. Proxies may be solicited by mail or facsimile, or by our directors, officers or employees, without extra compensation, in person or by telephone. We have retained Morrow & Co., LLC to assist in the solicitation of proxies for a fee of approximately $9,000 plus out-of-pocket expenses and telephone solicitation expenses. We will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding solicitation material to the beneficial owners of our common stock.

What if I have questions about the proposals?

        Questions concerning the proposals to be acted upon at the Annual Meeting should be directed to:

•

Our prohibition against directors and executive officers engaging in any hedging transaction with respect to our securities held by them.

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 stakeholders.

Code of Ethics for Senior Financial Professionals

        Our Code of Ethics for Senior Financial Professionals applies to our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer and other designated senior financial professionals. The key principles of this code include acting legally and ethically, promoting honest business conduct and providing timely and meaningful financial disclosures to our stockholders.

Complaint and Reporting Procedures for Accounting and Auditing Matters

        Our Complaint and Reporting Procedures for Accounting and Auditing Matters provide for (1) the receipt, retention and treatment of complaints, reports and concerns regarding accounting, internal accounting controls or auditing matters, and (2) the confidential, anonymous submission of complaints, reports and concerns by employees regarding questionable accounting or auditing matters, in each case relating to Dynegy. Complaints may be made through a toll free "Integrity Helpline" telephone number, operated by an independent third party, and a dedicated email address. Complaints received are logged by the Ethics and Compliance Office, communicated to the chairman of our Audit Committee and investigated, under the supervision of our Audit Committee, by our Internal Audit department or Ethics and Compliance Office. In accordance with applicable law, these procedures prohibit us from taking adverse action against any person submitting a good faith complaint, report or concern.

Policy for Communications with Directors

        Our Policy for Communications with Directors provides a means for stockholders and other interested parties to communicate with the Board. Under this policy stockholders and other interested parties may communicate with the Board or specific members of the Board by sending a letter to Dynegy Inc., Communications with Directors, Attn: Corporate Secretary, 601 Travis, Suite 1400, Houston, Texas 77002.

Director Attendance at Annual Meetings

        As detailed in our Corporate Governance Guidelines, Board members are requested and encouraged to attend the Annual Meeting. All of the members of the Board then in office attended last year's annual meeting held on May 21, 2013.

Board Risk Oversight

        The Board has ultimate responsibility for protecting stockholder value. Among other things, the Board is responsible for understanding the risks to which we are exposed, approving management's strategy to manage these risks, establishing policies that monitor and manage defined risks and measuring management's performance against the strategy. The Board's oversight responsibility for managing risk is detailed in our Risk Policy Statement.

        The Risk Policy Statement provides a structure around risk and defines the risks that we accept in the normal course of business. The Risk Policy Statement, in some instances, requires that separate policy

9

---

documentation be in place including Interest Rate Risk and Investment Policy, Disclosure Controls and Procedures Policy, Risk Management and Insurance Policy, Credit Risk Policy, Investment Policy (Employee Benefit Plans), and Commodity Risk Policy. Although not mandated by the Risk Policy Statement, our Delegation of Authority policy and the Code of Business Conduct and Ethics are complementary and critical to the risk management process. Our Executive Management Team is responsible for managing the above risks and reports on such matters to the applicable Board committees. Further, our Ethics and Compliance Office reports functionally to the Audit Committee Chairman and meets periodically with the Audit Committee. The Risk Policy Statement can be amended with the approval of our Audit Committee on behalf of the Board.

        The Audit Committee oversees the risks associated with the integrity of our financial statements and our compliance with legal and regulatory requirements. In addition, the Audit Committee discusses policies with respect to risk assessment and risk management, including major financial risk exposure and the steps management has taken to monitor and control such exposures. The Audit Committee reviews with management, internal auditors, and external auditors the accounting policies, the system of internal control over financial reporting and the quality and appropriateness of disclosure and content in the financial statements or other external financial communications. The Audit Committee also performs oversight of the business ethics and compliance program, reviews the programs and policies designed to assure compliance with our Code of Business Conduct and Ethics and applicable laws and regulations and monitors the results of the compliance efforts.

        The Compensation and Human Resources Committee, or Compensation Committee, oversees risks primarily associated with our ability to attract, motivate and retain quality talent, particularly executive talent, and disclosure of our executive compensation philosophies, strategies and activities. The Compensation Committee conducted a risk assessment in 2014 to reaffirm that our STI programs, including specifically the lack of separate plans or incentives for individual functions, do not encourage excessive risk-taking. This involved a review of a set of risk assessment considerations related to our short-term and long-term incentive programs. The goal of this effort was to establish a formal process for assessing and monitoring risk related to our compensation programs and for reviewing certain policies to ensure that the appropriate controls exist to mitigate any identified risk. Following this review, the Compensation Committee concluded that our STI programs collectively foster cooperation and focus award opportunities on measures that are aligned with our business strategy and the interests of our stockholders and do not encourage excessive risk-taking and risk-taking behaviors.

        The Nominating Committee oversees risks primarily associated with our ability to attract, motivate and retain quality directors, and our corporate governance programs and practices and our compliance therewith. Additionally, the Nominating Committee evaluates the performance of the Board, its committees and management annually and considers risk management effectiveness as part of their evaluation.

        The Finance and Commercial Oversight Committee oversees risks primarily with respect to oversight of our capital structure, financing and treasury matters and oversight of management's process for the identification, evaluation and mitigation of our financial and commercial related risks. Further, as part of their risk assessment responsibility, the Finance and Commercial Oversight Committee oversees our commodity risk monitored by our risk control group and receives regular reporting regarding commodity risk management effectiveness.

        The full Board oversees risks primarily associated with our commercial and operating performance and our environmental, health and safety performance. The full Board also receives quarterly updates from all Board committees, and they provide guidance to individual committee activities as appropriate.

Board Leadership Structure; Separation of Positions of Chairman and Chief Executive Officer

        As discussed in our Corporate Governance Guidelines, the Board believes the position of Chairman should be held by a non-management director and not the Chief Executive Officer. Mr. Flexon, as President and Chief Executive Officer, is responsible for setting the strategic direction for the Company and the day-to-day leadership and performance of the Company, while Mr. Wood, as Chairman, provides overall leadership to the Board in its oversight function. As such, he serves as the presiding director of executive sessions of the non-management and independent directors.

Stock Ownership Guidelines

        We have stock ownership guidelines for directors, members of the executive management team and other officers. We believe that a significant ownership stake by directors and officers leads to a stronger alignment of interests between directors, officers and stockholders. These guidelines, which were developed with the assistance of an independent compensation consultant, support our corporate governance focus and provide further alignment of interests among our directors and executive officers and stockholders.

Directors

        Each non-management director is expected to own a meaningful amount of Dynegy common stock; specifically, it is expected that within three years of joining the Board, a non-management director shall own at least the number of shares equivalent to three times their annual cash retainer. For purposes of this guideline: (1) each share of common stock owned on any date (a "measuring date") by a director shall be deemed to have a value equal to the greater of (a) the trading price of a share of the Company's common stock as of the date the applicable share was granted to the director or (b) the trading price of a share of the Company's common stock as of the measuring date; and (2) shares owned outright, phantom stock units, shares or units of restricted stock and shares subject to deferred compensation shall be counted as shares of common stock owned by the director (with the value thereof determined in accordance with clause (1) above).

Officers

        The shares counted for purposes of our officers' common stock ownership guidelines include shares owned outright, unvested restricted stock units, or RSUs, stock options (vested, in-the-money), and other share based equivalents that we may use from time to time. The holding requirements are expressed as a multiple of base salary and vary by level, as follows:

        Upon our emergence from bankruptcy on October 1, 2012 (the "Effective Date") and pursuant to the terms of our Plan of Reorganization, all outstanding equity awards of the Company as of the Effective Date were cancelled. As such, the stock ownership guidelines for our executives are subject to a mandatory five-year compliance period that started on the Effective Date, and executives are encouraged to accumulate one-fifth of their holding requirement during each year of the five-year period and may not sell any shares until executives have successfully met the holding requirement. The Nominating Committee will monitor each executive's progress toward the required holding requirement on an annual basis. At the end of the five-year period, if any executive fails to attain the required level of common stock ownership, action may be taken, in the discretion of the Nominating Committee considering all factors it deems relevant,

11

---

including awarding annual incentive cash bonuses in the form of restricted shares or requiring an executive to refrain from disposing of any vested shares and shares realized from any option exercise.

Affirmative Determinations Regarding Director Independence and Other Matters

        The Board previously determined that each of the following directors who served in 2013 are "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 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.

Director Nomination Process and Qualification Review of Director Nominees

Process

        Our director nominees are approved by the Board after considering the recommendation of the Nominating Committee. A copy of the Nominating Committee's charter is available in the "Corporate Governance" section of our web site at www.dynegy.com.

        Our Certificate of Incorporation provides that the number of our directors shall be fixed from time to time exclusively by our Board. The Board has fixed the number of our directors currently at seven, subject to adjustment by the Board in accordance with our Certificate of Incorporation.

        The Nominating Committee reviews annually the composition of the Board as a whole and recommends, if necessary, measures to be taken so that the Board reflects the appropriate balance of knowledge, experience, skills, expertise and diversity required for the Board as a whole and contains at least the minimum number of independent directors required by applicable laws and regulations. The Nominating Committee is responsible for ensuring that the composition of the Board accurately reflects the needs of our business and, in furtherance of this goal, proposing the nomination of directors for purposes of obtaining the appropriate members and skills. The Nominating Committee identifies nominees in various ways. The committee considers the current directors that have expressed an interest in and that continue to satisfy the criteria for serving on the Board as set forth in our Corporate Governance Guidelines. Other nominees that may be proposed by current directors, members of management or by stockholders are also considered. From time to time, the committee engages a professional firm to identify and evaluate potential director nominees.

12

---

Qualifications

        All director nominees, whether proposed by a stockholder or otherwise, are evaluated in accordance with the qualifications set forth in our Corporate Governance Guidelines. These guidelines require that directors possess the highest personal and professional ethics, integrity and values and be committed to representing the long-term interests of our stockholders at large. They must also have an inquisitive and objective perspective, practical wisdom, mature judgment and sufficient personal resources such that any director compensation to be received from the Company would not be sufficiently meaningful to impact their judgment in reviewing matters coming before the Board. Finally, they must be able to work compatibly with the other members of the Board and otherwise have the experience and skills necessary to enable them to serve as productive members of the Board. Directors also must be willing to devote sufficient time to carrying out their fiduciary duties and other responsibilities effectively and should be committed to serve on the Board for an extended period of time. For additional information, please read our Corporate Governance Guidelines.

        In connection with the director nominations for the 2014 Annual Meeting, the Nominating Committee also considered the nominees' (1) experience in the energy industry and understanding of the energy and commodity markets, (2) experience in finance and commercial risk management, (3) publicly traded company and board experience, (4) knowledge in the areas of laws and regulations related to environmental, health, safety, regulatory and other key industry issues, (5) strategic planning skills, (6) knowledge of corporate governance issues coupled with an appreciation of their practical application, and (7) accounting expertise, including audit, internal controls and risk management.

Diversity

        The Board does not have a formal policy with respect to Board nominee diversity. In recommending proposed nominees to the full Board, the Nominating Committee is charged with building and maintaining a board that has an ideal mix of talent and experience to achieve our business objectives in the current environment. In particular, the Nominating Committee is focused on relevant subject matter expertise, depth of knowledge in key areas that are important to us, and diversity of thought, background, perspective and experience so as to facilitate robust debate and broad thinking on strategies and tactics pursued by us.

Future director nominations

        For purposes of the 2015 Annual Meeting, the Nominating Committee will consider any director nominations from a stockholder received by the Corporate Secretary by the close of business on February 28, 2015, but not before the close of business on January 29, 2015. See "Future Stockholder Proposals" below for more information. Any such nomination must be accompanied in writing by all information relating to such person that is required under the federal securities laws, including such person's written consent to be named in the proxy statement as a nominee and to serve as a director if elected. The nominating stockholder must also submit its name and address, as well as that of the beneficial owner if applicable, and the number of shares of our common stock that are owned beneficially and of record by such stockholder and such beneficial owner. Finally, the nominating stockholder must discuss the nominee's qualifications to serve as a director as described in our Corporate Governance Guidelines.

PROPOSAL 1
ELECTION OF DIRECTORS

Directors

        Seven directors are to be elected at the Annual Meeting by the holders of common stock to each serve a one-year term. The directors are elected by a plurality of the shares of common stock represented in person (through internet access) or by proxy and entitled to vote on the election of directors, subject to our majority voting policy discussed below. This means that the seven individuals nominated for election to the Board as directors who receive the most FOR votes among votes properly cast in person (through internet access) or by proxy will be elected. Only FOR or WITHHELD votes are counted in determining whether a plurality has been cast in favor of a director nominee. Under our Certificate of Incorporation, stockholders do not have cumulative voting rights. If you withhold authority to vote with respect to the election of some or all of the director nominees, your shares will not be voted with respect to those nominees indicated. Under our majority voting policy, in an uncontested election, any director nominee who receives a greater number of votes WITHHELD for his or her election than votes FOR such election must offer his or her resignation to the Board promptly following certification of the stockholder vote. Broker non-votes are not counted for purposes of election of directors. You cannot abstain in the election of directors.

        Unless you withhold authority to vote or instruct otherwise, a properly executed proxy will be voted FOR the election of the nominees listed below as the proxies may determine. Although the Board does not contemplate that any of the nominees will be unable to serve, if such a situation arises prior to the Annual Meeting, the persons appointed as proxies will vote for the election of such other persons that may be nominated by the Board.

Information on Director Nominees

        All of the nominees for director are currently directors of Dynegy. Below is biographical information regarding the nominees, including their names, ages, business experience and qualifications to serve as a director, other directorships, if any, and the length of their service as a director of Dynegy.

COMPENSATION DISCUSSION AND ANALYSIS

        The following discussion should be read together with the compensation tables and disclosures for our Named Executive Officers included under "Executive Compensation." The following discussion contains statements regarding future company performance targets and goals. These targets and goals are disclosed in the limited context of our compensation programs and should not be considered as statements of our expectations or estimates of results or other guidance; to that end, these targets and goals will not be subject to updating.

        This Compensation Discussion and Analysis relates primarily to compensation decisions affecting 2013 compensation for our Named Executive Officers. For purposes of the 2013 Compensation Discussion and Analysis, our Named Executive Officers are anyone who served in 2013 as our Chief Executive Officer or Chief Financial Officer and the three other most highly compensated executive officers who were serving as executives at the end of 2013. These individuals are collectively referred to as our Named Executive Officers, and are identified below:

Executive Summary

2013 Business Highlights

        During 2013 we continued to firmly establish Dynegy's growth foundation. While the past twelve months marked another year of challenges in the merchant energy sector, throughout this period, as a result of our strong management team and experienced, skilled and committed employees, we were able to seize opportunities that furthered our strategic objective to grow the Company. Our overall performance in 2013 was note-worthy and continued to reflect our attention to capital deployment and effective execution of our business strategy. Consequently, we were able to deliver strong results for our stockholders and further position the organization to capitalize on the expected future dynamics that will impact the power industry. Our key accomplishments over the course of 2013 include:

•

Met updated Adjusted EBITDA guidance, (which excluded IPH), and exceeded Adjusted Free Cash Flow guidance;



•

Achieved the lowest recordable safety incidents in our history—a 35% reduction in employee recordable rate versus 2012;



•

Strengthened our balance sheet and liquidity through refinancing of debt, releasing $355 million of restricted cash, reduced posted collateral by over 40% and ended the year with $946 million of liquidity at Dynegy Inc. and $215 million of liquidity at IPH;



•

Reached a new four-year labor agreement with IBEW Local 51, the union which operates our Baldwin, Wood River, Hennepin and Havana coal plants;



•

Reached agreement with Southern California Edison for new multiyear energy and capacity supply contracts at our Moss Landing generation facility;



•

Completed the sales of the Roseton and Danskammer power generation facilities. Following final court proceedings, these two transactions concluded the bankruptcy reorganization of our

30

---

subsidiary, with Dynegy receiving approximately $1 million in cash, and an additional cash receipt of $12 million from the return of a previously issued letters of credit;

•

Acquired New Ameren Energy Resources, or AER, and its subsidiaries. Following the transaction, we now have more than 8,000 megawatts of generating capacity in Illinois (nearly 14,000 MW nationally) and gained entry into the retail and marketing businesses through Homefield Energy. Additionally, this combination created more than $95 million in labor, G&A and coal transportation synergies; and



•

Our continuous improvement program, Producing Results through Innovation by Dynegy Employees, or PRIDE, resulted in additional balance sheet improvements of $191 million and earnings improvements of $39 million.

Key Features of Our Compensation Program

        During the course of 2013, the Compensation Committee, with the assistance of Meridian Compensation Partners, conducted a comprehensive assessment of the compensation programs provided to our Named Executive Officers and other key employees. The objective was to ensure that our compensation programs and practices remain consistent with our stated compensation philosophy, are further aligned with the Company's business strategy and acknowledge evolving competitive practices and corporate governance standards. While no substantive changes were made, this process allowed the Compensation Committee to establish further clarity regarding the key features of our compensation program.

31

Compensation Philosophy and Program Objectives

Executive Compensation Philosophy

        Our executive compensation program, administered by the Compensation Committee, is primarily designed to attract, motivate and retain a highly qualified executive management team capable of effectively managing 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 corporate and individual performance.

        Continuing efforts initiated in late 2012, the Compensation Committee, engaged its independent consultant, Meridian Compensation Partners, to assess the compensation philosophy and programs provided to our Named Executive Officers and other key employees. This assessment included a review of our "Compensation Guiding Principles" which serve to formalize and document our compensation philosophy and provide a foundation for certain compensation decisions, as well as a common language for communicating those decisions to executives, employees and stockholders.

32

---

Executive Compensation Program Objectives

        Consistent with the stated purpose and the Compensation Guiding Principles listed above, the structure of our compensation program reflects the following key objectives: (1) Pay for Performance; (2) Market Competitiveness; and (3) Alignment with Stockholder Value.

        Pay for Performance.    We believe the variable components of compensation should not be viewed as entitlements, but rather should be awarded for delivering results relative to pre-determined business goals and objectives and for successfully executing our business strategy to create long-term value for our stockholders. At the start of the 2013 calendar year, the members of the Board and Compensation Committee reviewed and approved objectives to be used by executive management and the Board in assessing our 2013 annual performance.

        2013 Critical Success Factors.    Following a review of our strategic plan, the Compensation Committee approved in January 2013 the 2013 critical success factors and associated objectives and metrics to be used in determining STI funding for the 2013 performance year. The 2013 critical success factors are illustrated below.

        Similar to 2012, the 2013 critical success factors are each weighted, with financial performance being weighted most heavily, and include a number of supporting objectives and metrics that were used to evaluate performance throughout the year. "Financial Performance" represents our effort to meet or

33

---

exceed financial performance targets as measured by Adjusted EBITDA,¹ Adjusted Free Cash Flow,² and actions related to identifying sustainable fixed cash cost reductions and operating margin improvement opportunities across the organization. "Operational Excellence" and "Gross Margin Capture" represent our focus on efficient operating practices that achieve safety, environmental and reliability targets, complemented by commercial and asset management strategies focused on protecting and maximizing the value of our assets that provide near-term stability and preserve long-term flexibility. "Effective Corporate Support" primarily represents the internal efforts related to regulatory and investor relations strategies and outreach, maintaining a strong internal controls environment and our continuing focus on establishing a culture that is aligned with our purpose and core values. Finally, "Capital Allocation" represents our efforts related to growing the Company while increasing liquidity to create capital allocation opportunities and flexibility.

        Additionally, the Compensation Committee approved a financial performance requirement, or "gate", for the 2013 STI program, Adjusted Free Cash Flow. This separate funding gate served as the minimum performance level to be met before our STI award program was funded for any employee, including our Named Executive Officers. We believe this fosters alignment of the interests of our Named Executives Officers and employees with investor interests and our annual performance goals and objectives.

        These five critical success factors were used to assess the organization and the collective performance of our Named Executive Officers for the year. The objectives within each of the critical success factors have, where possible, quantifiable metrics used to evaluate the level of attainment achieved during 2013. Our progress, and the Named Executive Officers' contributions relative to these goals and objectives, was discussed throughout the year by the Board and Compensation Committee. Following year-end, compensation awards were determined by the Compensation Committee based upon their overall assessment of performance, including the degree to which these critical success factors and corresponding objectives were achieved. Please see Determining 2013 Short—Term Compensation below for details.

        Individual Performance.    In addition to the above described goals and objectives, executive compensation decisions are also based on individual performance. In particular, we defined our core values to reflect the key leadership qualities and behavioral attributes that all employees, including our Named Executive Officers, are expected to demonstrate and foster. These core values are: safety, accountability, collaboration, integrity and agility. In evaluating our Chief Executive Officer from this perspective, the Compensation Committee conducted an annual performance review together with the Board and evaluated his performance based on interaction with him and his performance throughout the year. Similarly, the Compensation Committee, which approves the compensation for our executive officers other than our Chief Executive Officer, consulted with the Chief Executive Officer as to his performance review of our other executive officers and their achievements relative to our objectives and core values.

        Market Competitiveness.    We believe that in order to attract and retain highly qualified executives, our executive compensation program must be competitive, both in elements and amount, with the broader labor market in which we compete for talent. To support our objective of paying market competitive compensation, the Compensation Committee conducts an annual competitive evaluation (including, among other things, a review of proprietary and proxy statement information) with its independent compensation consultant.

(1)

Adjusted EBITDA is defined 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 interest rate swaps and warrants, (iii) the impact of impairment charges and certain other costs such as those associated with AER acquisition, internal reorganization and bankruptcy proceedings, (iv) income or loss associated with discontinued operations, and (v) income or expense on up-front premiums received or paid for financial options in periods other than the strike periods.

(2)

Adjusted Free Cash Flow is defined as cash flow from operations less maintenance and environmental capital expenditures, the cash impact of the AER acquisition and debt refinance costs plus return on restricted cash. Adjusted Free Cash Flow also includes receipts or payments related to interest rate swaps and excludes the impact of changes in collateral.

34

        Independent Consultant.    Under its charter, the Compensation Committee has the authority to retain a compensation consultant. The Compensation Committee has retained Meridian since October 2012 as its independent consultant. Meridian was selected based upon the firm's depth and breadth of expertise in executive compensation and familiarity with our industry and organization. During 2013, services provided by Meridian included a comprehensive review and benchmarking of the compensation philosophy and programs provided to our Named Executive Officers and other executives, the collection and analysis of competitive executive and director compensation data, and updates regarding executive compensation trends and information regarding applicable legislative, regulatory and governance practices that may impact executive compensation practices and administration. Meridian reports to and acts at the sole discretion of the Compensation Committee, which is responsible for determining the scope of services performed. In August 2013, the Compensation Committee reviewed the independence factors adopted by the NYSE (and subsequently approved by the SEC in January 2013) for compensation consultants. The Compensation Committee considered Meridian's independence based on these factors and determined that no conflict of interest exists in the engagement with Meridian.

        Benchmarking.    At the request of the Compensation Committee, and in connection with the comprehensive executive compensation review conducted in 2012, over the course of 2013 Meridian conducted a benchmarking study to assess the competitiveness of the compensation of our Named Executive Officers. The benchmarking study provided competitive market compensation data derived from an industry-specific compensation survey and from proxy statements filed by companies in our industry that comprised our comparator group.

        Specifically, benchmark compensation data for positions with similar roles and responsibilities as our Named Executive Officers were compiled from the Towers Watson 2012 CDB Energy Services Executive Compensation Survey. These energy industry survey data were used to assess the market competitiveness of the compensation of our Named Executive Officers, as the data generally reflects the broader energy industry market in which we compete for executive talent. Please see the table in Annex A for a complete listing of the companies included in the energy industry survey data. The benchmarking study also analyzed publicly disclosed compensation data for the comparator companies to provide additional context for the Compensation Committee's executive compensation decisions. The comparator group used in the 2012 benchmarking study consisted of the following six companies with primary operations in the independent power producers, or IPP, segment of the energy industry: AES Corporation, Atlantic Power Corporation, Calpine Corporation, Genon Energy, NRG Energy, and TransAlta Corporation. This group of companies was consistent with those used in prior years' benchmarking studies. The Compensation Committee determined that benchmarking data from this comparator group, in conjunction with the energy industry survey data, provided a reasonable basis for assessing the competitiveness of the compensation for the Named Executive Officers.

        As a result of the comprehensive review conducted by Meridian in early 2013, the Compensation Committee decided to expand the comparator group of companies that will be used in the 2013 benchmarking study. Criteria used to evaluate the comparator group included financial metrics (assets, revenues, market capitalization and enterprise value), operational scope (i.e., merchant generation capacity and commodity focus) and market-based factors (i.e., competition for labor talent). The result was the adoption of a 12-company comparator group comprised of a combination of IPPs, electric utilities and multi-utilities (AES Corporation, Atlantic Power Corporation, Calpine Corporation, NRG Energy Inc., TransAlta Corporation, Edison International, Entergy Corporation, First Energy Corporation, PPL Corporation, Ameren Corporation, DTE Energy Company, and Public Service Enterprise Group).

        The comparator group data collected by Meridian included compensation pay practices, base salaries, target annual incentives, long-term incentive award levels and total compensation amounts for positions with similar roles and responsibilities as each of our Named Executive Officers, where available. In addition to assessing the competitiveness of compensation, the benchmark data is considered as a general

35

reference point by the Compensation Committee when making compensation decisions for our Named Executive Officers.

        Alignment with Stockholder Value.    Granting equity compensation awards to our employees, including our Named Executive Officers, is an important way that we align the interests of those individuals with the interests of our stockholders. The value of equity compensation is dependent upon the value of our common stock. Individuals who are granted equity compensation have a direct financial interest in the performance of that stock. An important aspect of our compensation philosophy is to provide eligible individuals with additional incentive and reward opportunities designed to enhance our long-term profitability and further align such individuals' interests with those of our stockholders. Please read "Elements of Compensation and 2013 Compensation—Long-Term Incentives" below for further discussion of Named Executive Officers' long-term incentives.

        Say on Pay.    At our annual meeting of shareholders held in May 2013, we received a favorable result on our Say on Pay proposal, with 99.8% of our stockholders represented in person (through internet access) or by proxy voting to approve the compensation of our Named Executive Officers. The Compensation Committee believes this result is an indication that a significant majority of our shareholders are satisfied with our executive compensation policies and decisions, and that our executive compensation program effectively aligns the interests of the Named Executive Officers with the interests of our shareholders. The Compensation Committee will continue to consider the outcomes of our Say on Pay votes when making future compensation decisions.

        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 bonuses 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.

Elements of Compensation and 2013 Compensation

        As previously noted, our Named Executive Officers are eligible to receive three primary elements of compensation: base salary; short-term cash incentive awards; and long-term incentive awards. The target allocation of our compensation elements places an emphasis on long-term incentives and is illustrated in the graphs below.

Base Salary

        Base salaries are the fixed, recurring cash portion of the Named Executive Officer's total compensation package. In determining the level of base salary for each Named Executive Officer, the

Compensation Committee considers job responsibilities, our budget for annual merit increases, external benchmark data (our comparator group and energy industry survey data as described above under "—Executive Compensation Philosophy—Market Competitiveness") of companies provided by its independent compensation consultant, internal pay equity, and the individual performance of each Named Executive Officer. The Compensation Committee exercises its judgment while considering competitive data, individual performance, internal pay equity, current position relative to the market and market value, among other factors, to determine base salaries for our Named Executive Officers.

        After not receiving a base salary increase since the start of his employment in 2011, the Compensation Committee recommended a modest base salary increase for Mr. Flexon effective March 2013. Additional annual increases will be considered in the future for Mr. Flexon based on the comparator group data, the Company's performance and his individual contributions. Similarly, Mr. Freeland, Ms. Burke and Ms. Callaway had not received a base salary adjustment since 2011. In each situation, salary increases were recommended to align their compensation with market competitive levels. Mr. Freeland received a more significant increase to reflect his performance, the complexity of his role and to better reflect his market position relative to the comparator group of companies in our industry. The base salary for Mr. Jones was set at $475,000 in connection with the start of his employment as Chief Commercial Officer on April 1, 2103.

Short-Term Incentive

        Short-term incentive, or STI, awards serve as a variable, at-risk element of each Named Executive Officer's total compensation package. The program is designed to provide our Named Executive Officers and eligible employees with STI rewards based on annual performance against specific identified financial, strategic, and operational goals that the Compensation Committee and the Board believe are critical to our success and the achievement of sustainable long-term total return to our stockholders. STI awards are paid in cash. The annual STI opportunity for each Named Executive Officer was established in their employment agreements (expressed as a percent of annual base salary), and have remained unchanged since 2011. The Named Executive Officers may be awarded STI awards in a range from zero to two times these STI target opportunities based on corporate performance and individual performance. Additionally, funding of STI awards is dependent upon successfully meeting the funding "gate". This separate funding gate serves as the minimum performance level that must be met before our STI award program is funded for any employee, including our Named Executive Officers. We believe this fosters the alignment of the interests of our Named Executives Officers with investor interests and our annual performance goals and objectives. Please read "Determining 2013 Short-Term Compensation" below for further discussion of the Named Executive Officers' STI awards for the 2013 performance period.

Long-Term Incentive

        Long-term incentives serve as the most significant performance based element of the executive's total compensation package. Our long-term incentive awards generally focus on the attainment of long-term performance goals and objectives, which are deemed instrumental in creating long-term value for stockholders and long-term retention incentives for our executives. Long-term incentive opportunities, in the form of equity based awards, typically do not fully vest until three years after the grant date. These equity awards are structured to achieve a variety of long-term objectives, including: attracting and retaining executives; aligning executives' financial interests with the interests of stockholders; and rewarding the achievement of long-term strategic goals and/or superior stock price performance. Long-term incentive awards are normally granted during the month of March each year but may also be granted in connection with the initial employment of executives.

        Historically, we granted a mix of stock options and RSUs to our Named Executive Officers. In 2013, the Compensation Committee determined it was appropriate to include performance based share units, or PSUs, into long-term incentive compensation. As such, we granted to each Named Executive Officer long-term incentive awards on March 18, 2013 comprised of 50% RSUs, 25% stock options and 25% PSUs. The Compensation Committee believes these awards will provide an appropriate balance of alignment with long-term stockholder interest and the retention of our Named Executive Officers. The Compensation Committee reviews the mix of long-term incentive awards for our Named Executive Officers, and will consider changes to the mix in the future as it deems appropriate.

        The table below illustrates the 2013 long-term incentive award grant value for each Named Executive Officer. In making decisions concerning long-term incentive awards made to our Named Executive Officers, the Compensation Committee considers competitive benchmarking data, the performance of the Company, individual performance of our Named Executive Officers, and other factors the Committee deems relevant. In the case of Mr. Jones, the long-term incentive award value represents the award granted to him in connection with the start of his employment on April 1, 2013 and was provided to acknowledge the significant forfeiture of incentive awards from his previous employer.

        PSUs are earned over a three-year performance period based upon our Total Shareholder Return, or TSR, over that period relative to a selected group of energy industry peer companies. In 2013, PSUs comprised 25% of the total target grant value of our long-term incentive awards. The number of PSUs awarded to each Named Executive Officer was based on the fair market value of our common stock on the day of grant. The Compensation Committee selected these companies, in consultation with Meridian, because of their similarity to us in business focus, as these companies represent a valuable reference point for evaluating the relative shareholder return. The Compensation Committee selected TSR as the performance measure because it directly aligns with the long-term interests of our stockholders. The key characteristics of the PSUs are as follows:

Performance Share Unit Structure

•

Three-year performance period (2013 through 2015)



•

Payout opportunity of 0-200% of target, intended to be settled in shares

38

---

•

Cumulative TSR percentile ranking calculated at end of performance period and applied to a pre-established payout scale to determine the number of earned/vested PSUs



•

If absolute TSR is negative, PSU award payouts will be capped at 100% of the target number of PSUs granted, regardless of relative TSR positioning

        Awards of RSUs are intended to support the attraction and retention of executives. As noted above, in 2013 RSUs comprised 50% of the total target grant value of our long-term incentive awards. The number of RSUs awarded to each Named Executive Officer was based on the fair market value of our common stock on the day of grant and the awards will vest equally in three annual installments on the anniversary of the grant date.

        Stock options comprised 25% of the total target grant value of our long-term incentive awards in 2013. Stock options are intended to align the Named Executive Officers with the interests of our stockholders because stock option value is directly tied to appreciation in the value of our stock. The number of stock options awarded to each Named Executive Officer was based on the Black Scholes value per share which is calculated based on the fair market value of our common stock on the day of grant. Stock options vest equally in three annual installments on the anniversary of the grant date and have an exercise price equal to the closing market price of our common stock on the grant date.

Retirement Benefit Plans

        Qualified benefit plans comprise additional elements of total compensation for our Named Executive Officers.

        Each Named Executive Officer is eligible, as are all our corporate employees, to participate in the Dynegy 401(k) Plan, which provides for a dollar-for-dollar match for each dollar contributed (on a pre-tax or Roth basis) up to 5% of salary (with such elective contributions capped at $17,500 for 2013). Our matching contributions to the Dynegy 401(k) Plan vest at a rate of 50% per year of service.

        Each Named Executive Officer is also eligible for a qualified pension benefit under the Dynegy Inc. Retirement Plan, or the Retirement Plan. This pension benefit, in the form of the Portable Retirement Benefit, or PRB, provides a defined benefit that grows each year at a variable rate (30-year Treasury rate). This benefit, introduced in 2001, provides an annual contribution of 6% of the Named Executive Officer's salary (with such salary capped at $255,000 for plan purposes for 2013). Dynegy contributions to the PRB vest at a rate of 33.33% per year of service.

        We do not maintain any supplemental executive retirement plans.

Executive Perquisites

        The Compensation Committee reviews executive perquisites on an annual basis. Each Named Executive Officer is eligible to receive annual reimbursement for reasonable costs incurred for individual tax and financial planning advice in an amount not to exceed $10,000 per year. Please read "Executive Compensation—Summary Compensation Table for 2011, 2012 and 2013" below for further details on executive perquisites.

39

---

        Overall, the total value of perquisites for our Named Executive Officers represents less than 1% of total compensation in 2013. While the Compensation Committee will continue to assess the competitiveness of executive perquisites, they believe the current limited use of this element of total compensation is appropriate.

Employment Agreements

        In building the current executive team, the former Compensation Committee concluded that, given the uncertainties faced by the Company, to attract talented and qualified executives it would be appropriate to enter into employment agreements. Therefore, during 2011, we entered into employment agreements with Mr. Flexon, Mr. Freeland, Ms. Burke and Ms. Callaway. In 2013, in an effort to treat the executives uniformly, we entered into a similar employment agreement with Mr. Jones upon his employment. Each of the employment agreements for our Named Executive Officers is set to expire on December 31, 2014; however, subject to 90 day notice to terminate by either the Company or the Named Executive Officer, each agreement will renew annually.

        As part of its assessment of our executive compensation programs and practices, in March 2013 the Compensation Committee approved certain changes to the employment agreements. These changes included the elimination of the Excise Tax Reimbursement provision for each Named Executive Officer. Coincident with this action, the Compensation Committee amended the Dynegy Inc. Executive Change in Control Severance Pay Plan, as amended, or Change in Control Plan, to implement a "Best Net" provision. Under the "Best Net" provision, benefits resulting from a change of control will be cut back if doing so results in greater after-tax proceeds to a covered participant absent such cut back. Otherwise, the participant will receive payment of all change of control related benefits and will be responsible for paying all excise tax imposed on such payments. The Compensation Committee also changed the STI language in the employee agreements to provide consistency between the agreements and the Dynegy Inc. Incentive Compensation Plan, or STI Plan. Key provisions contained in the employment agreements are described more fully below under "Potential Payments Upon Termination or Change in Control—Employment Agreements".

Change in Control and Severance Arrangements

        We have entered into arrangements and maintain plans under which specified payments and benefits would be provided to the Named Executive Officers in connection with a change in control. The Change in Control Plan provides for certain severance benefits payable in the event of an involuntary termination in connection with a change in control (i.e., "double trigger"). Also, certain long-term incentive award agreements provide for accelerated vesting of outstanding equity based awards in the event of a change in control. 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 change in control plans.

        We also maintain the Dynegy Inc. Executive Severance Pay Plan, as amended, or Executive Severance Pay Plan, that provides for payment of certain severance benefits in the event of a termination not in connection with a change in control. We believe the Executive Severance Pay Plan is an important competitive benefit that assists in the attraction and retention of critical talent. For details regarding the Executive Severance Pay Plan, please read "Executive Compensation—Potential Payments Upon Termination or Change in Control—Severance Eligible Terminations."

Determining 2013 Short-Term Incentive Compensation

2013 Performance Achievement

        The 2013 STI performance objectives were categorized into five "Critical Success Factors," which were approved by the Compensation Committee and Board in January 2013. Each Critical Success Factor

40

---

is weighted and consisted of a number of quantifiable performance metrics and targets. The performance for each is measured and results in a funding percentage for the overall STI program. In determining the overall performance achievement for 2013, the Compensation Committee considered the following results:

        Short-Term Incentive Awards.    Annual STI awards for our eligible employees, including the Named Executive Officers, are paid through an incentive pool that covered approximately 800 employees for the 2013 performance year. The final incentive funding pool is based on the results against our Critical Success Factors.

41

---

        To ensure that the 2013 STI performance objectives establish a direct link to the interests of our Named Executive Officers and stockholders, the Compensation Committee assessed performance against the Critical Success factors as well as strategic factors (e.g., the AER acquisition) to establish the size of the incentive pool to be used for the payment of annual incentive awards for the current year.

        Following review of year end performance against the Critical Success Factors the Compensation Committee determined the overall performance achievement for 2013. Based on the achievement levels on the quantitative and qualitative Critical Success factors described earlier, the Compensation Committee approved the funding level for the STI Plan for all employees, including our Named Executive Officers, at 112% of target.

        Individual Award Determination.    To determine STI awards for the organization, eligible employees, including the Named Executive Officers, establish performance goals at the start of the year. Progress is monitored throughout the year and supervisors are encouraged to provide feedback on performance against the objectives to employees on a regular basis. At year end, a final performance evaluation is conducted and employees are assessed across various rating categories based on both performance against their objectives as well performance relative to behavioral competencies that are linked to our values. These year end evaluations are used to determine the STI award each eligible employee receives, as employees had the opportunity to earn STI award payouts above or below the actual funding percentage based on their overall performance. A structured process is used to ensure a consistent application of the process is followed across the organization.

        The Compensation Committee determined the amount of each Named Executive Officers' award (in the case of the CEO the Compensation Committee recommended the award amount to the full Board) based on evaluation of their contributions during the year. In determining the 2013 STI awards, the key drivers considered by the Compensation Committee were the collective performance of our Named Executive Officers in managing and leading our business and their own subjective assessment of each Named Executive Officer's performance in managing his or her specific functions and the accomplishment of individual objectives.

        At year end, Mr. Flexon reviewed his assessment of each of his direct reports, including the Named Executive Officers, with the Compensation Committee. After considering these individual factors and the recommendations of Mr. Flexon (for the Named Executive Officers other than himself), the Compensation Committee concluded that the management team individually and collectively contributed to our accomplishments related to the critical success factors. On this basis, the Compensation Committee, and Board for Mr. Flexon, approved STI awards for Mr. Flexon, Mr. Freeland, Ms. Callaway, Ms. Burke and Mr. Jones. The chart below provides the approved STI award for each of the Named Executive Officers and the key accomplishments that formed the basis for each individual.

42

43

        In considering the award for Ms. Burke, Mr. Flexon and the Compensation Committee heavily weighted her individual contributions in terms of leading the AER integration efforts as well as her leadership in delivering value through our PRIDE program. In considering the awards for Ms. Callaway and Mr. Freeland, Mr. Flexon and the Compensation Committee wanted to reward Mr. Freeland's role in the refinancing efforts and enhancing our liquidity positions and similarly rewarded Ms. Callaway's role in negotiating the AER agreement and SCE settlement. Mr. Jones, who joined us in April and thus received a prorated award, provided notable contributions in the SCE agreement and was able to quickly identify and execute changes in our commercial hedging program. The Compensation Committee's recommendation, which was ultimately approved by the full Board, provided for a STI award for Mr. Flexon that reflected his leadership, vision and management that contributed to our noteworthy

44

financial and operational performance in 2013, spearheaded the AER acquisition and has positioned us for further success in 2014 and beyond.

Establishing 2014 Incentive Compensation

2014 Short-Term Incentive Opportunity

        Following a review of our 2014 strategic plan approved by the Board in December 2013, the Compensation Committee approved the 2014 critical success factors and associated objectives and metrics to be used in determining STI funding for the 2014 performance year. Building from our five year strategic plan, our 2014 Critical Success factors focus on three pillars, Customer Focus, Continuous Improvement, and Capital Allocation.

        Similar to 2013, the 2014 critical success factors are weighted, with financial performance weighted most heavily, and include a number of supporting objectives and metrics that will be used to evaluate performance throughout 2014. Additionally, the Compensation Committee approved a financial performance requirement, or "gate", for the 2014 STI program, Operating Cash Flow target. This separate funding "gate" will serve as the minimum performance level that must be met before our STI award program will be funded for any employee. We believe this fosters the alignment of executive interests with investor interests and our annual performance goals and objectives.

        Additionally, for our 2014 annual incentive program for all Named Executive Officers, and other members of our executive management team, we have established caps on the maximum payout at the beginning of the performance period based on 5% of final Adjusted EBITDA. The cap serves to set a maximum level of payout and does not establish entitlement to a payment at the level of the cap. The Compensation Committee, in connection with Meridian, also reviewed STI targets for our Named Executive Officers. We believe the target opportunities are appropriately positioned with the general industry and comparator group data and were unchanged from 2013.

        2014 Long-Term Incentive Opportunity.    We continue to move towards a total compensation mix that is weighted towards performance-based compensation (annual and long-term incentives), where actual amounts earned may differ from targeted amounts based on Company and individual performance. Each Named Executive Officer has a target total compensation opportunity that is assessed annually by the Compensation Committee to ensure alignment with the overall compensation objectives. For 2014, the Compensation Committee sought to increase the performance-based portion of the long-term incentive awards to provide increased alignment between the long-term interests of our Named Executive Officers

45

---

and those of our stockholders. As the chart below illustrates, the portion of PSUs has increased from 25% to 35% and correspondingly the portion of RSUs has decreased from 50% to 40%.

2014 LTI Allocation Mix

        The Compensation Committee believes this award mix will provide an appropriate balance of alignment with long-term stockholder interest and the retention of our Named Executive Officers.

Tax and Accounting Treatment of the Elements of Executive Compensation

        We account for stock-based compensation in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 718 (ASC 718).

        Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to public companies for individual compensation paid to the Chief Executive Officer and the other four highest compensated executive officers to the extent the compensation exceeds $1 million in any year. Performance-based compensation paid pursuant to a stockholder-approved incentive plan is not subject to the Section 162(m) limitations if certain requirements are met. As part of its role, the Compensation Committee reviews and considers the financial reporting and income tax deductibility of the compensation of our executive officers. Our policy is to utilize available tax deductions whenever appropriate and consistent with our compensation philosophy and objectives. However, the Compensation Committee retains the discretion to provide compensation to our executive officers that may not be fully deductible.

Pension Benefits

        The following table sets forth certain information with respect to the Retirement Plan and Restoration Pension Plan, except as otherwise noted, as they provide for payment at, following, or in connection with retirement for the Named Executive Officers as of December 31, 2013:

        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, including each Named Executive Officer's, salary, capped at $255,000 for 2013. 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.

51

---

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 18 of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2013.

Potential Payments Upon Termination or Change in Control

        We have entered into certain employment 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.

one-time lump-sum cash payment of $500,000. He participates in STI Plan with a target award of 75% of his base salary. He received a long-term incentive award in the amount of $2,200,000 which was converted on his employment commencement date in the following percentages: 50% as RSUs; 25% in the form of non-qualified stock options; and 25% in the form of PSUs.

        Furthermore, Mr. Jones is eligible to receive additional annual award grants pursuant to our long-term incentive programs and he participates in our other employee benefit plans and programs. Mr. Jones is entitled to participate in the Executive Severance Pay Plan and the Change in Control Plan; provided that, to the extent he is eligible to receive severance payable under the Executive Severance Pay Plan, the amount payable to Mr. Jones is increased by an amount equal to two times the current target award as in effect immediately prior to the date of the termination. Also, for purposes of the Executive Severance Pay Plan, Mr. Jones will be entitled to 24 months of base pay as severance pay. If Mr. Jones is terminated for any reason as described in his employment agreement, we are obligated to pay or provide to Mr. Jones (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. Jones'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.

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 long-term incentive award agreement.

        In addition, pursuant to our Executive Severance Pay Plan, our executives are entitled to payment of severance benefits if their employment is terminated due to a reduction in work force, a position elimination or an office closing, or 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 base salary. Severance benefits under the Executive Severance Pay Plan, which are payable in a lump sum, include:

•

severance pay equal to one month of base pay for each full, completed year of service with us and a pro-rated amount for each partial year of service, subject to the following requirements:



•

for the Chief Executive Officer, 24 months of base pay;



•

for any Executive Vice President, 12 months of base pay;

54

---

•

for any Senior Vice President, minimum nine months and a maximum of 12 months of base pay; and



•

for any Vice President or Managing Director, minimum six months and a maximum of 12 months of base pay;



•

continued participation in our group health care plan that provides medical and dental coverage for a period of time equal to the number of months of base pay such executive receives under the Executive Severance Pay Plan, 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; 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:

•

execution and performance of a confidentiality and nondisparagement agreement; 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 Name 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," as defined in the Change in Control Plan. In general, such an executive experiences an "involuntary termination" if such executive:

•

is terminated without cause; or



•

terminates for "good reason," generally meaning he or she suffers a material reduction in authority or duties, a material reduction in total compensation or relocation to a location 50 miles or more from the previous principal employment location.

        Severance benefits under the Change in Control Plan include:

•

a lump sum cash payment equal to:



•

for the Chief Executive Officer or Chief Operating Officer, 2.99 times such executive's "compensation," which is defined in the Change in Control Plan as the sum of any covered executive's (1) annual base salary based on the greatest rate in effect (a) immediately prior to the "change in control," (b) sixty days prior to the date of such executive's involuntary termination or (c) as of the date of such executive's involuntary termination and (2) target cash bonus under our STI Plan, for (a) the fiscal year in which the "change in control" occurs, (b) any fiscal year beginning after the fiscal year in which the "change in control" occurs and before the fiscal year in which such executive's involuntary termination occurs or (c) the fiscal year in which such executive's involuntary termination occurs, whichever is greatest;

55

---

•

for any Executive Vice President (other than the Chief Operating Officer), 2.50 times such executive's compensation;



•

for any Senior Vice President, 2.00 times such executive's compensation;



•

for any Vice President, 1.50 times such executive's compensation; or



•

for any Managing Director, 1.00 times such executive's compensation;



•

a lump sum cash payment equal to the aggregate target annual incentive compensation under any applicable STI Plan for the fiscal year during which such involuntary termination of employment occurs (determined as if all applicable goals and targets had been satisfied in full), pro-rated to the date of such executive's termination, plus the aggregate target annual incentive compensation under any applicable STI Plan earned but not yet paid (if any) for the fiscal year prior to the fiscal year during which the involuntary termination occurs;



•

all medical, dental, vision and life insurance benefits maintained for such executive as of the termination date, contingent upon continued payment of premiums by such executive at a cost that is no greater than the lesser of the cost of such coverage paid by such executive immediately prior to the date of the (a) executive's involuntary termination or (b) the "change in control" for a period equal to (1) 36 months from termination for the Chief Executive Officer, (2) 30 months from termination for any Executive Vice President, (3) 24 months from termination for any Senior Vice President, (4) 18 months from termination for any Vice President, and (5) 12 months from termination for any Managing Director;



•

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 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.

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

•

execution and performance of a confidentiality and nondisparagement agreement;



•

execution and performance of a non-solicitation agreement for a period of 24 months; and



•

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

Retirement

        As of December 31, 2013, 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.

56

---

        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 long-term 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 31, 2013, the last business day of the year; accordingly, values associated with long-term incentive awards made in March 2014 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 31, 2013 of $21.52;



•

The amounts shown as "Base salary" under the "Change in Control" column are the lump sum cash payments described as annual compensation under "—Change in Control";



•

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.

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.

AUDIT COMMITTEE REPORT

        Our Board has established an Audit Committee of independent directors, which operates under a written charter adopted by the Board. The charter is available in the "Corporate Governance" section of our web site at www.dynegy.com. The Audit Committee currently consists of three members: Messrs. Sult (Chair) and Barbas and Ms. Ackermann. The Board has determined that each member of the Audit Committee possesses the necessary level of financial literacy required to enable him or her to serve effectively as an Audit Committee member, and all members qualify as Audit Committee Financial Experts, including our designated Financial Expert, Mr. Sult, our Audit Committee Chair. For more information regarding each member of the Audit Committee's industry background and credentials, please read "Proposal 1—Election Of Directors—Information on Director Nominees." above. Our management is responsible for establishing a system of internal controls and for preparing our consolidated financial statements in accordance with generally accepted accounting principles. Our independent registered public accountants, Ernst & Young LLP, or EY, are responsible for auditing our consolidated financial statements and the effectiveness of our internal control over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (United States) and issuing their reports based on that audit. Under the Audit Committee's charter, the primary function of the Audit Committee is to assist the Board in fulfilling its oversight responsibilities as to, among other duties: (1) the integrity of our financial statements, including recommending to the Board the filing of our audited financial statements; (2) our disclosure controls and procedures and internal control over financial reporting; (3) our compliance with legal and regulatory requirements and Code of Business Conduct and Ethics; (4) the evaluation,

appointment and retention of our independent registered public accountants, including a review of their qualifications, services, independence, fees and performance; (5) the performance of our internal audit function; (6) the performance of our business ethics and compliance function; and (7) enterprise risk management process, policies and procedures. Further, the Audit Committee reviews in advance and pre-approves, explicitly, audit and permissible non-audit services provided to us by our independent registered public accountants. For more information regarding the Audit Committee's approval procedures, please read "Audit Committee Pre-Approval Policy" above. The Audit Committee is also directly responsible for reviewing with the independent registered public accountants the plans and scope of the audit engagement, reviewing with the independent registered public accountants their objectivity and independence and providing an open venue of communication between our management, the internal audit function, ethics and compliance function, the independent registered public accountants and the Board.

        In connection with the preparation of the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013:

•

The Audit Committee reviewed and discussed the audited financial statements and the effectiveness of our internal control over financial reporting with the independent registered public accountants and management.



•

The Audit Committee discussed with the independent registered public accountants the matters required to be discussed by Auditing Standard No. 16 "Communications with Audit Committees" as adopted by the Public Company Accounting Oversight Board. In general, these auditing standards require the independent registered public accountants to communicate to the Audit Committee certain matters that are incidental to the audit, such as any initiation of, or changes to, significant accounting policies, management judgments, accounting estimates and audit adjustments; disagreements with management; the independent registered public accountants' judgment about the quality of our accounting principles; significant audit risks identified and any changes from planned audit strategy; the use of specialists on the audit team; and issues for which the independent registered public accountants have consulted outside the engagement team.



•

The Audit Committee has received the written disclosures and the letter from the independent registered public accountants required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accountants' communication with the Audit Committee concerning independence, and has discussed the independent registered public accountants' independence with the independent registered public accountants. The Audit Committee also considered whether the independent registered public accountants' provision of non-audit services to us was compatible with maintaining their independence.

        Based on the review and discussions noted above, the Audit Committee recommended to the Board that the audited consolidated financial statements for the year ended December 31, 2013 be included in our Annual Report on Form 10-K filed with the SEC.

        This report is submitted by the members of the Audit Committee of the Board as of February 20, 2014:

John R. Sult, Chairman
Hilary E. Ackermann
Paul M. Barbas

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

Principal Accountant Fees and Services

        EY served as our independent registered public accountants for the years ending December 31, 2013 and 2012. Set forth below is a summary of the fees we paid EY for professional services rendered for the years ended December 31, 2013 and 2012.

        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.

CHARITABLE CONTRIBUTIONS

        During 2013, we did not make any contributions to any charitable organization in which an independent director served as an executive officer.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires our executive officers, directors and persons who own more than 10% of our equity securities to file reports of ownership and changes in ownership with the SEC and the NYSE. Executive officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file.

        Based solely upon a review of the copies of such forms furnished to us in 2013 and upon written representations that no Forms 5 were required, we believe that all persons subject to these reporting requirements filed the required reports on a timely basis.

TRANSACTIONS WITH RELATED PERSONS, PROMOTERS AND CERTAIN CONTROL PERSONS

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 www.dynegy.com.

PROPOSAL 2

APPROVAL OF COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

        A proposal will be presented at the meeting asking stockholders to approve on an advisory basis the compensation of Dynegy's Named Executive Officers as described in this proxy statement. Please see our "Compensation Discussion and Analysis" section beginning on page 30 for a discussion of our compensation program for our Named Executive Officers.

        Consistent with the stated purpose and the Compensation Guiding Principles described in our Compensation Discussion and Analysis, the structure of our compensation program reflects the following key objectives: (1) Pay for Performance; (2) Market Competitiveness; and (3) Alignment with Stockholder Value.

Key Features of Our Compensation Program

64

---

        The advisory vote on following resolution is not intended to address any specific element of compensation; rather, it relates to the overall compensation of the Company's named executive officers, as well as the philosophy, policies and practices described in this proxy statement. You have the opportunity to vote for, against or abstain from voting on the following resolution relating to executive compensation:

        THEREFORE, BE IT RESOLVED, that the stockholders of Dynegy approve, on an advisory basis, the compensation of Dynegy's Named Executive Officers listed in the 2013 Summary Compensation Table included in the proxy statement for this meeting, as such compensation is disclosed pursuant to Item 402 of Regulation S-K in this proxy statement under the section entitled "Executive Compensation," including the compensation tables and other narrative executive compensation disclosures set forth under that section, as well as the section in the proxy statement entitled "Compensation Discussion and Analysis."

        This advisory vote on the compensation of Dynegy's Named Executive Officers gives stockholders another mechanism to convey their views about Dynegy's compensation programs and policies. Although your vote on executive compensation is not binding on us, the Board values the views of stockholders. The Board and Compensation Committee will review the results of the vote and take them into consideration in addressing future compensation policies and decisions.

        The Board unanimously recommends that stockholders vote FOR the proposal to approve the compensation of our Named Executive Officers.

PROPOSAL 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

        The Audit Committee has appointed the firm of Ernst & Young LLP, or EY, as our independent registered public accountants for us and our subsidiaries for the fiscal year ending December 31, 2014, and the Board recommends that the stockholders ratify that appointment. Ratification requires the affirmative vote of a majority of the shares of common stock represented in person (through internet access) or by proxy at the meeting and entitled to vote on the matter. Unless you withhold authority to vote or instruct otherwise, a properly executed proxy will be voted FOR ratification of such appointment.

        Although there is no requirement that we submit the appointment of independent registered public accountants to stockholders for ratification or that the appointed auditors be terminated if the ratification fails, the Audit Committee will consider the appointment of other independent registered public accountants if the stockholders choose not to ratify the appointment of EY and may retain that firm or another without re-submitting the matter to our stockholders. Even if the appointment is ratified, the Audit Committee may terminate the appointment of EY as our independent registered public accountants without the approval of the stockholders whenever the Audit Committee deems such termination appropriate.

        Representatives of EY are expected to attend the Annual Meeting and will be available to respond to appropriate questions. The representatives will also have the opportunity to make a statement if they wish to do so.

        The Board unanimously recommends that stockholders vote FOR ratification of the appointment of Ernst & Young LLP as our independent registered public accountants for the fiscal year ending December 31, 2014.
