SUMMARY

The following summary highlights information contained elsewhere in this prospectus and therefore is not complete and does not contain all the information that you should consider before tendering Old Notes for exchange. You should read this entire prospectus carefully, including the documents incorporated by reference herein, which are described in the section entitled “Incorporation by Reference.”  You should also carefully consider, among other things, the matters discussed in the section entitled “Risk Factors.”

Our Business

We began operations in 1984 and became incorporated in the State of Delaware in 2007.  We are a holding company and conduct substantially all of our business operations through our subsidiaries.  Our primary business is the production and sale of electric energy, capacity and ancillary services from our fleet of sixteen operating power plants in six states totaling approximately 13,200 megawatts of generating capacity.

We operate a portfolio of generation assets that is diversified in terms of dispatch profile, fuel type and geography.  Our Coal and IPH segments are fleets of baseload coal facilities, located in Illinois, that dispatch around the clock throughout the year.  Our Gas segment operates both intermediate and peaking natural gas plants, located in the Midwest, Northeast and California.  The inherent cycling and dispatch characteristics of our intermediate combined cycle units allow us to take advantage of the volatility in market pricing in the day-ahead and hourly markets.  This flexibility allows us to optimize our assets and provide incremental value.  Peaking facilities are generally dispatched to serve load only during the highest periods of power demand, such as hot summer and cold winter days.  In addition to generating power, our generating facilities also receive capacity revenues through structured markets or bilateral tolling agreements, as local utilities and independent system operators (“ISOs”) seek to ensure sufficient generation capacity is available to meet future market demands.

We sell electric energy, capacity and ancillary services on a wholesale basis from our power generation facilities.  In connection with the AER Acquisition on December 2, 2013, we began serving residential, municipal, commercial and industrial consumers through our Homefield Energy retail business in Illinois.  Wholesale electricity customers will, for reliability reasons and to meet regulatory requirements, contract for rights to capacity from generating units.  Ancillary services are the products of a power generation facility that support the transmission grid operation, follow real-time changes in load and provide emergency reserves for major changes to the balance of generation and load.  Retail electricity customers produce energy and these related services in the deregulated retail energy market.  We sell these products individually or in combination to our customers for various lengths of time from hourly to multi-year transactions.

We do business with a wide range of customers, including: regional transmission organizations and ISOs, integrated utilities, municipalities, electric cooperatives, transmission and distribution utilities, power marketers, financial participants such as banks and hedge funds, and residential, commercial and industrial end-users.  Some of our customers, such as municipalities or integrated utilities, purchase our products for resale in order to serve their retail, commercial and industrial customers.  Other customers, such as some power marketers, may buy from us to serve their own wholesale or retail customers or as a hedge against power sales they have made.

Our Corporate Information

Our principal executive offices are located at 601 Travis, Suite 1400, Houston, Texas 77002.  Our telephone number is (713) 507-6400 and we have a website accessible at www.dynegy.com.  The information posted on our website is not incorporated into this prospectus and is not part of this prospectus.

SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

The selected financial information presented below was derived from, and is qualified by reference to, our audited consolidated financial statements, including the notes thereto, incorporated by reference in this prospectus.

This information is only a summary.  You should read the data set forth in the table below in conjunction with the section entitled “Selected Financial Data” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which is incorporated by reference in this prospectus.

As described in Note 1—Organization and Operations to our consolidated financial statements incorporated by reference in this prospectus, Legacy Dynegy merged with DH on September 30, 2012.  The accounting treatment of the Merger was reflected as a recapitalization of DH and, similar to a reverse merger, DH was the surviving accounting entity for financial reporting purposes.  Therefore, our historical results for periods prior to the Merger are the same as DH’s historical results.

As a result of the application of fresh-start accounting as of the October 1, 2012, the financial statements on or prior to October 1, 2012 are not comparable with the financial statements after October 1, 2012.  References to “Successor” refer to Dynegy after October 1, 2012, after giving effect to the application of fresh-start accounting.  References to “Predecessor” refer to Dynegy on or prior to October 1, 2012.  Additionally, on October 1, 2012, the DNE Debtor Entities did not emerge from bankruptcy; therefore, we deconsolidated our investment in these entities as of October 1, 2012.  Accordingly, the results of operations of the DNE Debtor Entities are presented in discontinued operations for all periods presented.

Table of Contents

(1)         We completed the DMG Transfer effective September 1, 2011; therefore, the results of our coal segment are only included through August 31, 2011, and are excluded from our balance sheet for the period ended December 31, 2011. See Note 23—Dispositions and Discontinued Operations to our audited consolidated financial statements incorporated by reference in this prospectus for further discussion.

(2)        We completed the DMG Acquisition effective June 5, 2012; therefore, the results of our Coal segment are only included subsequent to June 5, 2012. See Note 3—Merger and Acquisition to our audited consolidated financial statements incorporated by reference in this prospectus for further discussion.

(3)         The results of operations for the period January 1, 2012, through October 1, 2012, includes the effects of the plan of reorganization and impacts of fresh-start accounting related to the DH bankruptcy.  See “Selected Financial Data” in the 10-K for the period ended December 31, 2012, incorporated by reference in this prospectus.

(4)         Includes $46 million and $21 million of debt extinguishment costs for the years ended December 31, 2009 and 2011, respectively.

·                  Bluegrass power generating facility (sold fourth quarter 2009); and

·                  Heard County power generating facility (sold second quarter 2009).

(6)         As a result of the DH Chapter 11 Cases, we reclassified approximately $3.6 billion in long-term debt to liabilities subject to compromise as of December 31, 2011. These liabilities were settled upon our emergence from bankruptcy on October 1, 2012. See Note 21—Emergence from Bankruptcy and Fresh-Start Accounting to our audited consolidated financial statements incorporated by reference in this prospectus for further discussion.

RISK FACTORS

An investment in the Notes involves risk.  You should carefully consider the following factors, together with the risks and uncertainties discussed in the section entitled “Cautionary Note Regarding Forward Looking Statements” and the other information incorporated by reference in this prospectus, including the information included in the section entitled “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.  Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also impair our business operations. We cannot assure you that any of the events discussed in this prospectus will not occur.  If they do, our business, financial condition or results of operations could be materially and adversely affected.  In such case, the trading price of our securities, including the Notes, could decline, and you might lose all or part of your investment.

Risks Related to the Exchange Offer and Holding the Exchange Notes

Holders who fail to exchange their Old Notes will continue to be subject to restrictions on transfer and may have reduced liquidity after the exchange offer.

If you do not exchange your Old Notes for Exchange Notes in the exchange offer, you will continue to be subject to the restrictions on transfer applicable to the Old Notes.  The restrictions on transfer of your Old Notes arise because we issued the Old Notes under exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws.  In general, you may only offer or sell the Old Notes if they are registered under the Securities Act and applicable state securities laws, or offered and sold under an exemption from these requirements.  We do not plan to register the Old Notes under the Securities Act.  In addition, we have not conditioned the exchange offer on receipt of any minimum or maximum principal amount of outstanding notes.  As Old Notes are tendered and accepted in the exchange offer, the principal amount of remaining Old Notes will decrease.  This decrease could reduce the liquidity of the trading market for the Old Notes.  We cannot assure you of the liquidity, or even the continuation, of the trading market for the Old Notes following the exchange offer.

You must comply with the exchange offer procedures in order to receive new, freely tradable Exchange Notes.

Delivery of Exchange Notes in exchange for Old Notes tendered and accepted for exchange pursuant to the exchange offer will be made only after timely receipt by the exchange agent of the following:

·                  certificates for Old Notes or a book-entry confirmation of a book-entry transfer of Old Notes into the exchange agent’s account at DTC, New York, New York as depository, including an agent’s message (as defined herein) if the tendering holder does not deliver a letter of transmittal;

·                  a completed and signed letter of transmittal (or facsimile thereof), with any required signature guarantees, or an agent’s message in lieu of the letter of transmittal; and

·                  any other documents required by the letter of transmittal.

Therefore, holders of Old Notes who would like to tender Old Notes in exchange for Exchange Notes should be sure to allow enough time for the Old Notes to be delivered on time.  We are not required to notify you of defects or irregularities in tenders of Old Notes for exchange.  Old Notes that are not tendered or that are tendered but we do not accept for exchange will, following consummation of the exchange offer, continue to be subject to the existing transfer restrictions under the Securities Act and, upon consummation of the exchange offer, certain registration and other rights under the Registration Rights Agreement will terminate.  See “The Exchange Offer—Procedures for Tendering Old Notes” and “The Exchange Offer—Consequences of Exchanging or Failing to Exchange Old Notes.”

Some holders who exchange their Old Notes may be deemed to be underwriters and these holders will be required to comply with the registration and prospectus delivery requirements in connection with any resale transaction.

If you exchange your Old Notes in the exchange offer for the purpose of participating in a distribution of the Exchange Notes, you may be deemed to have received restricted securities and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

10

Table of Contents

The Exchange Notes and the guarantees will be unsecured and effectively subordinated to our existing secured indebtedness and any future secured indebtedness.

The Exchange Notes and the guarantees will be general unsecured senior obligations and will be effectively subordinated to all of our existing and future secured debt and that of each Subsidiary Guarantor, including obligations under the Credit Agreement, to the extent of the value of the collateral securing such debt.

If we or a Subsidiary Guarantor are declared bankrupt, become insolvent or are liquidated or reorganized, any of our secured debt or that of a Subsidiary Guarantor will be entitled to be paid in full from our assets or the assets of the Subsidiary Guarantor, as applicable, securing that debt before any payment may be made with respect to the Notes or the affected guarantees.  Holders of the Notes will participate ratably in our remaining assets with all holders of our unsecured indebtedness that does not rank junior to the Notes, including all of our other general creditors, based upon the respective amounts owed to each holder or creditor.  In any of the foregoing events, there may not be sufficient assets to pay amounts due on the Notes.  As a result, holders of the Notes would likely receive less, on a ratable basis, than holders of secured indebtedness. See “Summary Description of the Exchange Notes—Ranking.”

We may be unable to purchase the Exchange Notes upon a change of control.

Upon the occurrence of a change of control, you will have the right to require us to repurchase your Exchange Notes at a purchase price in cash equal to 101% of the principal amount of your Exchange Notes plus accrued and unpaid interest, if any, to but excluding the date of purchase.  The Credit Agreement contains, and any future credit agreement or other agreements relating to indebtedness to which we become a party may contain, prohibitions of certain events, including events that would constitute a change of control.  The exercise by the holders of Exchange Notes of their right to require us to repurchase the Notes upon a change of control could cause a default under these other agreements, even if the change of control itself is not due to the financial effect of such repurchases on us or otherwise.  In the event a change of control occurs at a time when we are prohibited from purchasing Exchange Notes, we could seek the consent of the applicable lenders to the purchase of Exchange Notes or could attempt to refinance the indebtedness that contains such prohibitions.  If we do not obtain a consent or repay that indebtedness, we will remain prohibited from purchasing Exchange Notes.  Our failure to make the change of control offer or to pay the change of control purchase price when due would result in a default under the Indenture governing the Exchange Notes which, in turn, would constitute a default under the Credit Agreement and the documents governing our other indebtedness.  In addition, we may not have sufficient financial resources to satisfy all of our obligations under the Exchange Notes and our other indebtedness.  Finally, the change of control feature of the Exchange Notes does not cover all corporate reorganizations, mergers or similar transactions and may not provide you with protection in a highly leveraged transaction.  See “Description of the Exchange Notes—Change of Control.”

If an active trading market does not develop for the Exchange Notes you may not be able to resell them.

The Exchange Notes are a new issue of securities and there is no established trading market for the Exchange Notes.  We cannot assure you that an active trading market will develop for the Exchange Notes.  If no active trading market develops, you may not be able to resell your Exchange Notes at their fair market value or at all.  Future trading prices of the Exchange Notes will depend on many factors, including, among other things, prevailing interest rates, our operating results and the market for similar securities.  We do not intend to apply for listing the Exchange Notes on any securities exchange or for inclusion of the Exchange Notes in any automated quotation system.  Historically, the market for non-investment grade debt has been subjected to disruptions that have caused substantial volatility in the prices of securities similar to the Exchange Notes offered hereby.  The market for the Exchange Notes, if any, may be subject to similar disruptions.  Any such disruptions may adversely affect the value of your Exchange Notes.

Risks Related to the Notes

Our indebtedness could adversely affect our financial health, limit our ability to compete and prevent us from fulfilling our obligations under the Notes.

As of December 31, 2013, we had $2.1 billion of indebtedness.  In addition, as of March 11, 2014, we had approximately $205 million in letters of credit outstanding under our Revolving Facility, which excludes the revolving credit facility at IPM.  Our indebtedness could have important consequences. For example, it may:

·                  make it more difficult for us to satisfy our financial obligations, including those relating to the Notes;

·                  limit our ability to enter into long-term revenue contracts that require credit support;

·                  limit our ability to plan for or respond to, and increasing our vulnerability to, changing business, governmental regulation and economic conditions and to withstand competitive pressures, general economic and industry conditions or a downturn in our business;

·                  require a substantial portion of our cash flow from operations to be used for debt payments and reduce our ability to use cash flow to fund working capital, capital expenditures and other general corporate purposes;

·                  place us at a competitive disadvantage relative to companies that have less indebtedness;

·                  limit our ability to obtain financing in the future for working capital, capital expenditures, acquisitions or other purposes on acceptable terms, on a timely basis or at all; and

·                  cause a decline in our credit ratings.

Further, if gas, power, and capacity prices, where applicable, do not improve, our ability to service our debt obligations will be adversely affected and may require significant operational and balance sheet restructurings.

We and our subsidiaries may be able to incur additional indebtedness in the future. The terms of the Indenture and the agreements governing our other indebtedness, including the Credit Agreement, do not fully prohibit us or our subsidiaries from doing so.  Additionally, in certain cases, we are permitted to incur other indebtedness which would be effectively senior to the Notes. If new debt is added to current debt levels, the related risks could intensify.

The Credit Agreement contains, and agreements we enter into in the future may contain, covenants that significantly restrict our operations.

The Credit Agreement contains covenants imposing financial and operating restrictions on our business. These restrictions may affect our ability to operate our business, may limit our ability to take advantage of potential business opportunities as they arise and may adversely affect the conduct of our current business, including restricting our ability to finance future operations and capital needs and limiting our ability to engage in other business activities. These covenants will place restrictions on our ability and the ability of our operating subsidiaries to, among other things:

·                  incur additional debt or issue some types of preferred shares;

·                  declare or pay dividends, repurchase or redeem stock or make other distributions to stockholders;

·                  create liens;

·                  make certain restricted investments;

·                  enter into transactions with affiliates;

·                  enter into any agreements which limit the ability of certain subsidiaries to make dividends or otherwise transfer cash or assets to us or certain other subsidiaries;

12

Table of Contents

·                  sell or transfer assets; and

·                  consolidate or merge.

In addition, the Credit Agreement contains financial covenants, if we have utilized 25% or more of our Revolving Facility, that specify maximum thresholds for our senior secured leverage ratio (as defined in the Credit Agreement).  These restrictions may also limit our ability to obtain future financings, withstand a future downturn in our business or the economy in general, or otherwise conduct necessary corporate activities.  We may also be prevented from taking advantage of business opportunities that arise because of the limitations that the restrictive covenants under the Credit Agreement impose on us.  Agreements we enter into in the future may also have covenants that restrict our operations.

A breach of any covenant in the Indenture governing the notes, the Credit Agreement or the agreements governing our other indebtedness would result in a default under that agreement after any applicable grace periods. A default, if not waived, could result in acceleration of the debt outstanding under such agreement and in a default with respect to, and acceleration of, the debt outstanding under any other debt agreements. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to make all of the required payments or borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us. See “Description of the Exchange Notes—Events of Default and Remedies.”

The Indenture governing the Notes will not contain financial covenants or meaningful restrictions on us or our subsidiaries.

Neither we nor any of our subsidiaries will be restricted from incurring additional debt or other liabilities under the Indenture. We may from time to time incur additional debt and other liabilities.  The Indenture will not require us to achieve or maintain any minimum financial results relating to our financial condition or results of operations.  In addition, we will not be restricted from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock under the Indenture.

To service our indebtedness, we will require a significant amount of cash.  Our ability to generate cash depends on many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness, including the Notes and the Credit Agreement, and to fund planned capital expenditures and other strategic investments will depend on our ability to generate cash in the future.  This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.  We may not generate sufficient cash flow from operations and we cannot assure you that future borrowings will be available to us in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs.  If we cannot make scheduled payments on our indebtedness, we will be in default and the holders of the Notes could declare all outstanding principal and interest to be due and payable, the lenders under the Credit Agreement could terminate their commitments to loan money, the lenders could foreclose against the assets securing their borrowings and we could be forced into bankruptcy or liquidation.  All of these events could result in your losing your investment in the Notes.

Our ability to refinance the Credit Agreement, the Notes and any other future indebtedness depends on many factors beyond our control.

We may need to refinance all or a portion of our indebtedness on or before maturity.  Our ability to refinance the Credit Agreement, the Notes, and any other future indebtedness will depend on the condition of the capital markets and our financial condition at such time and could be limited by restrictive covenants in our existing and future debt agreements.  We cannot provide assurances that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.  If refinancing is not available to us, we may not have sufficient cash to enable us to meet all of our obligations, including payments on the Notes and our other indebtedness.

Your right to receive payments on the Notes could be adversely affected if any of our non-guarantor subsidiaries declare bankruptcy, liquidate, or reorganize.

The Notes will be jointly and severally guaranteed by each of our current and future wholly-owned domestic subsidiaries that from time to time is a borrower or guarantor under our Credit Agreement.  Not all of

13

Table of Contents

Dynegy’s subsidiaries guarantee the Notes.  See “Description of the Exchange Notes—Subsidiary Guarantees.”  Accordingly, claims of holders of the Notes will be structurally subordinated to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon liquidation or otherwise, to us or a guarantor of the Notes.  The Indenture will not limit the ability of these subsidiaries to incur certain additional debt or other liabilities.  In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us.

Dynegy’s indirect, wholly-owned subsidiary, IPH, acquired the AER Entities on December 2, 2013. The AER Entities will not guarantee the Notes.

A court could cancel the guarantees of the Notes by our subsidiaries under fraudulent transfer law.

Each of our current and future wholly-owned domestic restricted subsidiaries that from time to time is a borrower or guarantor under the Credit Agreement will guarantee the Notes.  Although the guarantees provide you with a direct claim against the assets of the Subsidiary Guarantors, under federal bankruptcy law and comparable provisions of state fraudulent transfer laws, in certain circumstances a court could cancel a guarantee and order the return of any payments made thereunder to the Subsidiary Guarantor or to a fund for the benefit of its creditors.

A court might take these actions if it found, among other things, that when the Subsidiary Guarantor incurred the debt evidenced by its guarantee, including when the Subsidiary Guarantor entered into its guarantee of the Credit Agreement (i) it received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee and (ii) any one of the following conditions was satisfied:

·                  the Subsidiary Guarantor was insolvent or was rendered insolvent by reason of the incurrence;

·                  the Subsidiary Guarantor was engaged in a business or transaction for which its remaining assets constituted unreasonably small capital; or

·                  the Subsidiary Guarantor intended to incur, or believed (or reasonably should have believed) that it would incur, debts beyond its ability to pay as those debts matured.

In applying the above factors, a court would likely find that a Subsidiary Guarantor did not receive fair consideration or reasonably equivalent value for its guarantee, except to the extent that it benefited directly or indirectly from the issuance of the Notes or borrowing under the Credit Agreement.  The determination of whether a Subsidiary Guarantor was or was rendered “insolvent” when it entered into its guarantee will vary depending on the law of the jurisdiction being applied.  Generally, an entity would be considered insolvent if the sum of its debts (including contingent or unliquidated debts) is greater than the fair market value of its assets, if the present fair salable value of its assets is less than the amount that will be required to pay its probable liability on its existing debts, including contingent or unliquidated debts, as they become absolute and matured or if it is unable to pay its debts.

If a court cancelled a Subsidiary Guarantor’s guarantee, you would no longer have a claim against that Subsidiary Guarantor or its assets.  Our assets and the assets of the remaining Subsidiary Guarantors may not be sufficient to pay amounts then due under the Notes.

The Notes will be guaranteed by each of our wholly-owned domestic subsidiaries that is a borrower or guarantees the Credit Agreement or any indebtedness that refinances the Credit Agreement.  If such a subsidiary is released from its guarantee of the Credit Agreement or such other indebtedness, it will automatically be released from its guarantee of the Notes.

The Notes will be guaranteed by each of our wholly-owned domestic subsidiaries that is a borrower or guarantees the Credit Agreement or any indebtedness that refinances the Credit Agreement.  If such a subsidiary is released from its guarantee of the Credit Agreement or such other indebtedness, it will automatically be released

14

Table of Contents

from its guarantee of the Notes without the consent of the holders of the Notes.  The Credit Agreement provides that a subsidiary guarantee may be released under certain circumstances.  For example, our Credit Agreement: (i) permits our Subsidiary Guarantors to enter into certain permitted transactions as a result of which such Subsidiary Guarantor ceases to be a subsidiary and (ii) allow us to designate any of our subsidiaries as an unrestricted subsidiary or excluded project subsidiary so long as certain conditions are satisfied, the effect of which, in each case, would be to release such subsidiary from its guarantee obligations or to not require a guarantee from such subsidiary.  See “Description of the Exchange Notes—Subsidiary Guarantees.”

Changes in the public debt ratings of the Notes may materially and adversely alter the cost and the terms and conditions of our future financings and the value and liquidity of the Notes.

The Notes will be, and any of our future debt instruments may be, publicly rated by Standard & Poor’s and Moody’s, which are independent rating agencies.  These public debt ratings may affect our ability to incur debt in the future.  Any future downgrading of ratings assigned to the Notes, our other debt instruments or Dynegy by either rating agency may affect the cost and terms and conditions of our future financings and could adversely affect the value and liquidity of the Notes.

RATIO OF EARNINGS TO FIXED CHARGES

The following table presents our ratio of earnings to fixed charges for the historical periods indicated.

(1)         For purposes of computing the ratio of earnings to fixed charges, “earnings” are defined as pre-tax income from continuing operations before adjustment for earnings from equity investments plus fixed charges. “Fixed charges” consist of interest, whether capitalized or expensed (excluding the effect of interest rate swaps), amortization of debt expense and the estimated interest component of rent expense.

(2)         For the years ended December 31, 2009, 2010, 2011, for the period from October 2 through December 31, 2012 and the year ended December 31, 2013 earnings were insufficient to cover fixed charges by $1,107 million, $406 million, $587 million, $113 million, and $423 million, respectively.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma condensed consolidated financial information (the “Pro Forma Financial Information”) sets forth selected historical consolidated financial information for Dynegy.  The historical data provided for the year ended December 31, 2013 is derived from our audited annual consolidated financial statements which has been incorporated by reference into this prospectus.

The unaudited pro forma condensed consolidated statement of operations is presented for the fiscal year ended December 31, 2013.

The Pro Forma Financial Information is provided for informational and illustrative purposes only and should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and related notes in Dynegy’s Annual Report on Form 10-K for the year ended December 31, 2013 which have been incorporated by reference into this prospectus.

The pro forma adjustments, as described in the notes to the unaudited pro forma condensed consolidated financial statement are based on currently available information.  Management believes such adjustments are reasonable, factually supportable and directly attributable to the following events and transactions:

·                  AER Acquisition.  On December 2, 2013, pursuant to the terms of the definitive agreement dated as of March 14, 2013 (the “AER Transaction Agreement”) by and between IPH and Ameren, IPH completed its acquisition from Ameren 100 percent of New AER for no cash or stock consideration. Pursuant to the AER Transaction Agreement, IPH indirectly acquired New AER’s subsidiaries, including (i) Genco, (ii) AERG, (iii) Ameren Energy Fuels and Services Company and (iv) AEM. Dynegy has provided a limited guaranty of certain obligations of IPH up to $25 million (the “Limited Guaranty”) as described below.

On December 2, 2013, prior to the completion of the AER Acquisition, IPH and Ameren entered into an amendment to the AER Transaction Agreement, in the form of a letter agreement (the “Letter Agreement”). The Letter Agreement, among other things, (i) identified additional post-closing credit support Ameren is to provide to IPH pursuant to the terms therein, (ii) provided that Ameren will be obligated to pay an additional amount of between $25 million and $35 million with respect to certain disputed wholesale customer contracts, (iii) provided that Ameren would cause an additional approximately $4 million of cash, in aggregate, to be retained at AEM, (iv) provided that Ameren will be contingently liable up to approximately $4 million with respect to certain railroad lease termination fees, (v) requires Ameren to maintain and continue certain guarantees in connection with certain existing contractual obligations, pursuant to the terms therein, and (vi) requires Ameren to provide post-closing litigation support to IPH in connection with certain disputes under specified contracts.

The transaction did not include AER’s gas-fired power generation facilities: Elgin, Gibson City and Grand Tower (the “Put Assets”).  AERG, Genco and Medina Valley, a former affiliate of AER that IPH did not acquire in the transaction, entered into an amendment to a put option agreement (the “Put Option Agreement”) whereby the Put Assets were to be sold by Genco, subject to approval by FERC, to Medina Valley for a minimum of $133 million (the “Put Transaction”).  On October 11, 2013, the Put Transaction was consummated following receipt of approval of FERC under Section 203 of the Federal Power Act, as amended (“FERC Approval”).  Pursuant to the AER Transaction Agreement, Ameren will cause Medina

18

Table of Contents

Valley to pay Genco minimum after-tax proceeds of approximately $138 million. Additionally, Genco may receive after-tax net proceeds realized in excess of $138 million following the closing of the sale of the Put Assets by Medina Valley to Rockland Capital.

In connection with the AER Acquisition, Ameren will retain certain historical obligations of AER and its subsidiaries, including certain historical environmental and tax liabilities.  Genco’s approximately $825 million in aggregate principal amount of notes will remain outstanding as an obligation of Genco. The debt bears interest at rates from 6.30 percent to 7.95 percent and matures between 2018 and 2032.  Additionally, Ameren is required to maintain its existing credit support, including all of its collateral obligations with respect to AEM, for a period not to exceed two years.

In addition to the Put Transaction proceeds, Ameren was required at closing to ensure that a minimum of $85 million of cash, plus approximately $8 million primarily for the proceeds of certain real estate sales, was available at New AER and its subsidiaries.  Approximately $70 million of cash, plus the proceeds of the Put Transaction described above are held at Genco.

Each party has agreed to indemnify the other for breaches of representations and warranties, breaches of covenants and certain other matters, subject to certain exceptions.

Concurrently with the execution of the AER Transaction Agreement, Dynegy entered into the Limited Guaranty, capped at $25 million in favor of Ameren, pursuant to which we guaranteed payout by IPH of any required termination fee and, for a period of two years after the closing (subject to certain exceptions), up to $25 million with respect to IPH’s indemnification obligations and certain reimbursement obligations under the AER Transaction Agreement.

We are required to record the assets and liabilities acquired in the AER Acquisition at their estimated fair values as of the closing date. We have not yet completed our analysis of the fair value of New AER’s assets and liabilities given the complexities inherent in the valuation; therefore, the purchase price allocation used in the preparation of the unaudited pro forma condensed consolidated financial statements included herein should be considered preliminary.  Actual results could vary materially from the Pro Forma Financial Information. In addition, the adjustments related to the AER Acquisition do not reflect any of the synergies and cost reductions that may result from the AER Transaction Agreement.

DYNEGY INC.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS

(a)              Represents our consolidated statement of operations for the period indicated as reported in the Dynegy Form 10-K for the year ended December 31, 2013, as filed with the SEC on February 27, 2014 and incorporated by reference herein.

(b)             Represents AER’s unaudited consolidated statement of operations for the period ended November 30, 2013.  Certain reclassifications have been made to the historical presentation in order to conform to Dynegy’s presentation.

(c)              Represents the removal of $20 million of Dynegy’s Acquisition and integration costs due to the AER Transaction Agreement, which are non-recurring.

(d)             The decrease in Revenues is comprised of the following:

·   The elimination of $19 million of revenues associated with the Put Assets as these assets were not acquired by Dynegy;

·   The inclusion of $35 million in mark-to-market losses due to the elimination of AER’s cash flow hedge accounting as Dynegy will not elect to designate qualifying derivative instruments as cash flow hedges subsequent to the completion of the acquisition.  Eliminating cash flow hedge accounting results in the changes in the value of derivatives being recorded through Revenue instead of through Accumulated other comprehensive income; and

·   The inclusion of $30 million of amortization of intangible assets related to retail capacity purchase contracts and power sales contracts.

(e)              The decrease in Cost of sales is comprised of the following:

·   The elimination of $17 million of cost of sales associated with the Put Assets as these assets were not acquired by Dynegy;

·    The inclusion of $55 million of amortization of intangible liabilities related to coal and transportation contracts.

(f)               Represents the adjustment to reflect:

·   The reclassification of $26 million of allocated corporate costs to General and administrative expense to conform to Dynegy’s policy.  AER classified allocated corporate costs as Operating and maintenance expense and Dynegy classifies these costs as General and administrative expense; and

(g)              Represents the adjustment to reflect:

·   The effect of the purchase accounting adjustments, which decreased depreciation expense by $63 million due to the reduction of property, plant and equipment ;

·   The removal of $1 million in depreciation expense associated with accretion expense for the asset retirement obligations of the Hutsonville and Meredosia plants being retained by Ameren.

(h)             Reflects the adjustment to eliminate impairments recognized by AER related to the Put Assets which were not acquired by Dynegy.

(i)               Reflects the reclassification of $26 million of allocated corporate costs from Operating and maintenance expense to General and administrative expense as discussed in (f) above.

(j)               Represents the impact of adjusting Genco’s $825 million in senior notes to their estimated fair value of $682 million as of December 2, 2013, resulting in increased amortization of the discount through interest expense.

(k)             Eliminates the income tax benefit recorded by Ameren.  Dynegy’s net deferred tax assets are fully reserved.  For purposes of the unaudited pro forma condensed consolidated statements of operations, Dynegy has assumed any change in our net deferred taxes would be offset by changes in the valuation allowance.

(l)               Represents the reversal of 20% of depreciation expense reduction discussed in footnotes (g) associated with Electric Energy, Inc. (“EEI”), due to AER’s indirect 80% ownership interest in EEI.

(m)     Eliminates the income tax benefit recorded by Ameren.  Dynegy’s net deferred tax assets are fully reserved.  For purposes of the unaudited pro forma condensed consolidated statements of operations, Dynegy has assumed any change in our net deferred taxes would be offset by changes in the valuation allowance.

(n)         Represents the reversal of 20% of depreciation expense reduction discussed in footnotes (i) and (bb) associated with Electric Energy, Inc. (“EEI”), due to AER’s indirect 80% ownership interest in EEI.

(p)         Represents AER’s audited consolidated statement of operations for the year ended December 31, 2012 as incorporated by reference herein. Certain reclassifications have been made to the historical presentation in order to conform to Dynegy’s presentation.

(q)         Represents the effect of the DMG Transfer, which increased Revenues by $230 million, partially offset by a decrease in Revenues of $69 million due to the amortization of intangible assets and liabilities related to capacity contracts, energy contracts and tolling agreements as a result of the application of fresh-start accounting.

(r)            Represents (i) the effect of the DMG Transfer, which increased Cost of sales by $132 million, and (ii) the effect of fresh-start adjustments, which increased Cost of sales by $32 million due to the amortization of intangible assets and liabilities related to coal and transportation contracts.

(u)         Represents the effect of the DMG Transfer, which increased General and administrative expenses by $14 million partially offset by a decrease of $1 million due to the reduction of other postretirement employee benefit and pension expense as a result of the application of fresh-start accounting.

(v)         In connection with the DMG Acquisition, Dynegy recorded an impairment of the Undertaking receivable, affiliate that was established in connection with the DMG Transfer.  As the pro forma statement of operations

23

Table of Contents

assumes the DMG Transfer never occurred, the impairment of the Undertaking receivable, affiliate has been eliminated.

(w)       Removes the interest income associated with the Undertaking receivable, affiliate.

(x)         Dynegy’s net deferred tax assets were fully reserved as of December 31, 2012. Therefore, there is no tax impact related to the pro forma adjustments as we have assumed any changes to our net deferred taxes would be offset by changes in the valuation allowance.

(y)         The decrease in Revenues is comprised of the following:

·                  The elimination of $58 million of revenues associated with the Put Assets as these assets were not acquired by Dynegy;

·                  The inclusion of $159 million in mark-to-market losses due to the elimination of AER’s cash flow hedge accounting as Dynegy does not plan to elect to designate qualifying derivative instruments as cash flow hedges subsequent to the completion of the acquisition.  Eliminating cash flow hedge accounting results in the changes in the value of the derivatives being recorded through Revenue instead of through Accumulated other comprehensive income; and

·                  The inclusion of $27 million of amortization expense related to intangible assets for power sales contracts.

(z)          Removes the $40 million in Cost of sales associated with the Put Assets as they were not acquired by Dynegy.

(aa)  Represents the adjustment to reflect:

·                  The reclassification of $44 million of allocated corporate costs from Operating and maintenance expense to General and administrative expense to conform to Dynegy’s policy; and

·                  The removal of $9 million in Operating and maintenance expense associated with the Put Assets as they were not acquired by Dynegy.

(bb)  Represents the adjustment to reflect:

·                  The effect of the purchase accounting adjustments, which decreased depreciation expense by $66 million due to the $2.005 billion reduction of property, plant and equipment (as discussed in note (h) to the unaudited pro forma condensed consolidated balance sheet included herein);

·                  The elimination of $21 million in depreciation expense related to the Put Assets as they were not acquired by Dynegy; and

·                  The removal of $2 million in depreciation expense associated with accretion expense for the asset retirement obligations of the Hutsonville and Meredosia plants which were retained by Ameren.

We expressly reserve the right to amend or terminate the exchange offer, and not to accept for exchange any Old Notes, upon the occurrence of any of the conditions of the exchange offer specified in the section entitled “Summary—Conditions to the Exchange Offer;” provided, however, that if we amend the exchange offer to make a material change, including the waiver of a material condition, we will extend the exchange offer, if necessary, to keep the exchange offer open for at least five business days after such amendment or waiver is published, sent or given to the holders of the Old Notes.  We will give oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the Old Notes as promptly as practicable.  Such notice, in the case of any extension, will be issued by means of a press release or other public announcement no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

Procedures for Tendering Old Notes

The tender to us of Old Notes by you as set forth below and our acceptance of the Old Notes will constitute a binding agreement between us and you upon the terms and subject to the conditions set forth in this prospectus and in the accompanying letter of transmittal.  Except as set forth below, to tender Old Notes for exchange pursuant to the exchange offer, you must transmit a properly completed and duly executed letter of transmittal, including all other documents required by such letter of transmittal or, in the case of a book-entry transfer, an agent’s message in lieu of such letter of transmittal, to Wilmington Trust, National Association, as exchange agent, at the address set forth in the section entitled “—Exchange Agent” on or prior to the Expiration Date.  In addition, either:

·                  certificates for such Old Notes must be received by the exchange agent along with the letter of transmittal; or

·                  a timely confirmation of a book-entry transfer (a “book-entry confirmation”) of such Old Notes, if such procedure is available, into the exchange agent’s account at DTC pursuant to the procedure for book-entry transfer must be received by the exchange agent, prior to the Expiration Date, with the letter of transmittal or an agent’s message in lieu of such letter of transmittal.

The term “agent’s message” means a message, transmitted by DTC to and received by the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from the tendering participant stating that such participant has received and agrees to be bound by the letter of transmittal and that we may enforce such letter of transmittal against such participant.

The method of delivery of Old Notes, letters of transmittal and all other required documents is at your election and risk.  If such delivery is by mail, it is recommended that you use registered mail, properly insured, with

return receipt requested.  In all cases, you should allow sufficient time to assure timely delivery.  No letter of transmittal or Old Notes should be sent to us.

Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed unless the Old Notes surrendered for exchange are tendered:

·                  by a holder of the Old Notes who has not completed the box entitled “Special Issuance Instructions” or “Special Delivery Instructions” on the letter of transmittal; or

·                  for the account of an eligible institution (as defined below).

In the event that signatures on a letter of transmittal or a notice of withdrawal are required to be guaranteed, such guarantees must be by a firm which is a member of the Securities Transfer Agent Medallion Program, the Stock Exchanges Medallion Program or the New York Stock Exchange Medallion Program (each such entity being hereinafter referred to as an “eligible institution”).  If Old Notes are registered in the name of a person other than the signer of the letter of transmittal, the Old Notes surrendered for exchange must be endorsed by, or be accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as we or the exchange agent determine in our sole discretion, duly executed by the registered holders with the signature thereon guaranteed by an eligible institution.

We, or the exchange agent in our sole discretion, will make a final and binding determination on all questions as to the validity, form, eligibility (including time of receipt) and acceptance of Old Notes tendered for exchange.  We reserve the absolute right to reject any and all tenders of any particular Old Note not validly tendered or to not accept any particular Old Note which acceptance might, in our judgment or our counsel’s, be unlawful.  We also reserve the absolute right to waive any defects or irregularities or conditions of the exchange offer as to any particular Old Note either before or after the Expiration Date (including the right to waive the ineligibility of any holder who seeks to tender Old Notes in the exchange offer).  Our or the exchange agent’s interpretation of the term and conditions of the exchange offer as to any particular Old Note either before or after the Expiration Date (including the letter of transmittal and the instructions thereto) will be final and binding on all parties.  Unless waived, any defects or irregularities in connection with tenders of Old Notes for exchange must be cured within a reasonable period of time, as we determine.  We are not, nor is the exchange agent or any other person, under any duty to notify you of any defect or irregularity with respect to your tender of Old Notes for exchange, and no one will be liable for failing to provide such notification.

If the letter of transmittal is signed by a person or persons other than the registered holder or holders of Old Notes, such Old Notes must be endorsed or accompanied by powers of attorney signed exactly as the name(s) of the registered holder(s) that appear on the Old Notes.

If the letter of transmittal or any Old Notes or powers of attorney are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing.  Unless waived by us or the exchange agent, proper evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

By tendering Old Notes, you represent to us that, among other things, the Exchange Notes acquired pursuant to the exchange offer are being obtained in the ordinary course of business of the person receiving such Exchange Notes, whether or not such person is the holder and that neither the holder nor such other person has any arrangement or understanding with any person, to participate in the distribution of the Exchange Notes.  In the case of a holder that is not a broker-dealer, that holder, by tendering, will also represent to us that the holder is not engaged in, and does not intend to engage in, a distribution of the Exchange Notes.

However, any purchaser of Old Notes who is our affiliate, who intends to participate in the exchange offer for the purpose of distributing the Exchange Notes or a broker-dealer that acquired Old Notes in a transaction other than as part of its trading or market-making activities and who has arranged or has an understanding with any person to participate in the distribution of the Old Notes:

·                  cannot rely on the applicable interpretations of the staff of the SEC; and

·                  must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

Each broker-dealer that receives Exchange Notes for its own account in exchange for Old Notes, where such Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Notes.  See “Plan of Distribution.”  The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

Acceptance of Old Notes for Exchange; Delivery of Exchange Notes

Upon satisfaction or waiver of all of the conditions to the exchange offer, we will accept, promptly after the Expiration Date, all Old Notes validly tendered and will issue the Exchange Notes promptly after the Expiration Date.  See “Summary—Conditions to the Exchange Offer.”  For purposes of the exchange offer, we will be deemed to have accepted validly tendered Old Notes for exchange if and when we give oral (confirmed in writing) or written notice to the exchange agent.

The holder of each Old Note accepted for exchange will receive an Exchange Note in the amount equal to the surrendered Old Note.  Holders of Exchange Notes will receive interest accruing from the most recent date to which interest has been paid on the Old Notes, unless the record date for the first interest payment date after the consummation of the exchange offer preceded such date of consummation, in which case the interest payable on such interest payment date will be paid to the holders of the Old Notes.

In all cases, issuance of Exchange Notes for Old Notes that are accepted for exchange will be made only after timely receipt by the exchange agent of:

·                  certificates for Old Notes or a timely book-entry confirmation of such Old Notes into the exchange agent’s account at DTC;

·                  a properly completed and duly executed letter of transmittal or an agent’s message in lieu thereof; and

·                  all other required documents.

If any tendered Old Notes are not accepted for any reason set forth in the terms and conditions of the exchange offer or if Old Notes are submitted for a greater principal amount than the holder desires to exchange, such unaccepted or non-exchanged Old Notes will be returned without expense to the tendering holder (or, in the case of Old Notes tendered by book entry transfer into the exchange agent’s account at DTC pursuant to the book-entry procedures described below, such non-exchanged Old Notes will be credited to an account maintained with DTC promptly after the Expiration Date or termination of the exchange offer) promptly after the Expiration Date, as applicable.

Book-Entry Transfers

For purposes of the exchange offer, the exchange agent will request that an account be established with respect to the Old Notes at DTC within two business days after the date of this prospectus, unless the exchange agent has already established an account with DTC suitable for the exchange offer.  Any financial institution that is a participant in DTC may make book-entry delivery of Old Notes by causing DTC to transfer such Old Notes into the exchange agent’s account at DTC in accordance with DTC’s procedures for transfer.  Although delivery of Old Notes may be effected through book-entry transfer at DTC, the letter of transmittal or facsimile thereof or an agent’s message in lieu thereof, with any required signature guarantees and any other required documents, must, in any case, be transmitted to and received by the exchange agent at the address set forth in the section entitled “—Exchange Agent” on or prior to the Expiration Date.

Withdrawal Rights

You may validly withdraw your tender of Old Notes at any time prior to the Expiration Date.  To be effective, a written notice of withdrawal must be received by the exchange agent at one of the addresses set forth in the section entitled “—Exchange Agent.”  This notice must specify:
