COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Basis of Presentation (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

GenOn Energy, Inc., a wholly-owned subsidiary of NRG, is a wholesale power generator engaged in the ownership and operation of power generation facilities, with approximately 20,242 MW of net electric generating capacity located in the U.S.

GenOn Americas Generation is a wholesale power generator with approximately 7,852 MW of net electric generating capacity located, in many cases, near major metropolitan areas. GenOn Americas Generation's electric generating capacity is part of the 20,242 MW of net electric generating capacity of GenOn.

GenOn Mid-Atlantic operates and owns or leases 4,683 MW of net electric generating capacity in Maryland near Washington, D.C. GenOn Mid-Atlantic’s electric generating capacity is part of the 7,852 MW of net electric generating capacity of GenOn Americas Generation. GenOn Mid-Atlantic’s generating facilities serve the Eastern PJM markets.

GenOn Americas Generation and GenOn Mid-Atlantic are Delaware limited liability companies and indirect wholly-owned subsidiaries of GenOn. GenOn Mid-Atlantic is a wholly-owned subsidiary of NRG North America and an indirect wholly-owned subsidiary of GenOn Americas Generation.

The Registrants sell power from their generation portfolio, offer capacity or similar products to retail electric providers and others, and provide Ancillary Services to support system reliability.

This is a combined quarterly report of the Registrants for the quarter ended September 30, 2013. The notes to the condensed consolidated financial statements apply to the Registrants as indicated parenthetically next to each corresponding disclosure. The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with the SEC's regulations for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the Registrants' financial statements set forth in the 2012 Form 10-K. Interim results are not necessarily indicative of results for a full year.

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary to present fairly the Registrants' consolidated financial positions as of September 30, 2013, and the results of operations, comprehensive loss and cash flows for the three and nine months ended September 30, 2013, and 2012.

NRG Merger, Predecessor and Successor Reporting

On December 14, 2012, NRG completed the acquisition of GenOn with GenOn continuing as a wholly-owned subsidiary of NRG. The NRG Merger is accounted for under the acquisition method of accounting. Fair value adjustments related to the NRG Merger have been pushed down to GenOn, GenOn Americas Generation and GenOn Mid-Atlantic, resulting in certain assets and liabilities of the Registrants being recorded at fair value at December 15, 2012. See Note 3, NRG Merger, for further discussion.

The Registrants’ consolidated statements of operations subsequent to the NRG Merger include amortization expense relating to fair value adjustments and depreciation expense based on the fair value of the Registrants’ property, plant and equipment. In addition, effective with the NRG Merger, the Registrants adopted accounting policies of NRG. Therefore, the Registrants' financial information prior to the NRG Merger is not comparable to its financial information subsequent to the NRG Merger.

As a result of the impact of pushdown accounting, the financial statements and certain note presentations separate the Registrants' presentations into two distinct periods, the period before the consummation of the NRG Merger (labeled predecessor) and the period after that date (labeled successor), to indicate the application of different basis of accounting between the periods presented.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Reclassifications

Certain prior-year amounts have been reclassified for comparative purposes. The reclassification did not affect results from operations. The Registrants reclassified certain balances from cash and cash equivalents to funds deposited by counterparties, which impacted cash flows from operations in the prior year.

Note 2 — Summary of Significant Accounting Policies (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

Recent Accounting Developments

ASU 2011-11 — Effective January 1, 2013, the Registrants adopted the provisions of ASU No. 2011-11, Balance Sheet (Topic 210) Disclosures about Offsetting Assets and Liabilities, or ASU No. 2011-11, and began providing enhanced disclosures regarding the effect or potential effect of netting arrangements on an entity's financial position by improving information about financial instruments and derivative instruments that either (1) offset in accordance with either ASC 210-20-45 or ASC 810-20-45 or (2) are subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset. Reporting entities are required to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The disclosures required by ASU No. 2011-11 are required to be adopted retroactively. As this guidance provides only disclosure requirements, the adoption of this standard did not impact the Registrants' results of operations, cash flows or financial position.

ASU 2013-02 (GenOn) - Effective January 1, 2013, the Registrants adopted the provisions of ASU No. 2013-02, Other Comprehensive Income (Topic 220) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, or ASU No. 2013-02, and began reporting the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income within the notes to the financial statements if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income in the same reporting period. For other amounts not required by U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures which provide additional information about the amounts. The provisions of ASU No. 2013-02 are required to be adopted prospectively. As this guidance provides only presentation requirements, the adoption of this standard did not impact GenOn's results of operations, cash flows or financial position.

Note 3 — NRG Merger (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

On December 14, 2012, NRG completed the acquisition of GenOn. Consideration for the acquisition was valued at $2.2 billion and was comprised of 0.1216 shares of NRG common stock for each outstanding share of GenOn, including restricted stock units outstanding on the acquisition date, except for fractional shares which were paid in cash.

The acquisition was recorded as a business combination, with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair values on the acquisition date. The initial accounting for the business combination is not complete because the evaluations necessary to assess the fair value of certain net assets acquired is still in process. See Note 3, NRG Merger, in the Registrants' 2012 Form 10-K for additional information related to the NRG Merger.

The following tables summarize the historical carrying amounts, the acquisition accounting adjustments, the preliminary acquisition-date fair value and the measurement period adjustments through September 30, 2013 to the provisional allocation for assets acquired and liabilities assumed initially recorded in 2012 due to the ongoing evaluation of initial estimates. The allocation of the purchase price may be modified up to one year from the date of acquisition as more information is obtained about the fair value of assets acquired and liabilities assumed.

The estimated fair values of the property, plant and equipment were significantly lower than the book value, which reflects changes to expected market dynamics, including commodity prices, resulting in lower estimated cash flows and in some cases, shorter useful lives of the underlying assets. The measurement period adjustments for property, plant and equipment primarily reflect revisions of various estimates based on additional information available. In addition, the difference between the historical tax basis of the assets and liabilities over the net amount assigned to the assets and liabilities in acquisition accounting was recorded as a net deferred tax asset. Based on cumulative pre-tax losses, a valuation allowance for the full amount of the net deferred tax assets was also recorded.

Note 4 — Fair Value of Financial Instruments (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

This footnote should be read in conjunction with the complete description under Note 5, Fair Value of Financial Instruments, to the Registrants' 2012 Form 10-K.

For cash and cash equivalents, funds deposited by counterparties (GenOn), accounts receivable, note receivable — affiliate (GenOn Americas Generation), accounts payable, accrued expenses and other current liabilities, restricted cash, and cash collateral paid and received in support of energy risk management activities, the carrying amount approximates fair value because of the short-term maturity of those instruments and are classified as Level 1 within the fair value hierarchy.

The estimated carrying amounts and fair values of GenOn and GenOn Americas Generation’s long-term debt, including current portion, are as follows:

GenOn



	As of September 30, 2013				As of December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In millions)
Long-term debt, including current portion	$	3,135	$	3,066	$	4,185	$	4,195

GenOn Americas Generation



	As of September 30, 2013				As of December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In millions)
Long-term debt, including current portion	$	940	$	902	$	946	$	953

The fair value of GenOn and GenOn Americas Generation's publicly-traded long-term debt is based on quoted market prices and is classified as Level 1 within the fair value hierarchy. The fair value of GenOn's non publicly-traded long-term debt is estimated using current interest rates for similar instruments with equivalent credit quality and is classified as Level 3 within the fair value hierarchy.

Recurring Fair Value Measurements

Derivative assets and liabilities and trust fund investments are carried at fair market value. Realized and unrealized gains and losses included in earnings that are related to energy derivatives are recorded in operating revenues and cost of operations.

GenOn

The following tables present assets and liabilities (including affiliate amounts) measured and recorded at fair value on GenOn’s consolidated balance sheet on a recurring basis and their level within the fair value hierarchy. On July 22, 2013, concurrent with the initial public offering of NRG Yield, Inc., GenOn sold its ownership interests in NRG Marsh Landing Holdings LLC to NRG Yield LLC, which included assuming the interest rate swap liability.

Derivative Fair Value Measurements

A portion of the Registrants' contracts are exchange-traded contracts with readily available quoted market prices. A majority of the Registrants' contracts are non-exchange-traded contracts valued using prices provided by external sources, primarily price quotations available through brokers or over-the-counter and on-line exchanges. For the majority of the Registrants' markets, the Registrants receive quotes from multiple sources. To the extent that the Registrants receive multiple quotes, the Registrants' prices reflect the average of the bid-ask mid-point prices obtained from all sources that the Registrants believe provide the most liquid market for the commodity. If the Registrants receive one quote, then the mid-point of the bid-ask spread for that quote is used. The terms for which such price information is available vary by commodity, region and product. A significant portion of the fair value of the Registrants' derivative portfolio is based on price quotes from brokers in active markets who regularly facilitate those transactions and the Registrants believe such price quotes are executable. The Registrants do not use third party sources that derive price based on proprietary models or market surveys. The remainder of the assets and liabilities represents contracts for which external sources or observable market quotes are not available for the whole term or for certain delivery months. These contracts are valued using various valuation techniques including but not limited to internal models that apply fundamental analysis of the market and corroboration with similar markets. As of September 30, 2013, contracts valued with prices provided by models and other valuation techniques make up 2% of GenOn's derivative assets and 6% of GenOn's derivative liabilities, 2% of GenOn Americas Generation’s derivative assets and 3% of GenOn Americas Generation's derivative liabilities and 0% of GenOn Mid-Atlantic’s derivative assets and 0% of GenOn Mid-Atlantic's derivative liabilities.

The fair value of each contract is discounted using a risk free interest rate. In addition, the Registrants apply a credit reserve to reflect credit risk which is calculated based on published default probabilities. To the extent that the Registrants’ net exposure under a specific master agreement is an asset, the Registrants use the counterparty's default swap rate. If the net exposure under a specific master agreement is a liability, the Registrants use their default swap rate. The credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the Registrants’ liabilities or that a market participant would be willing to pay for the Registrants’ assets. The Registrants' credit reserves were as follows:

Concentration of Credit Risk

In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies, to the Registrants' 2012 Form 10-K, the following is a discussion of the concentration of credit risk for the Registrants’ financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Registrants are exposed to counterparty credit risk through various activities including wholesale sales and fuel purchases.

Counterparty Credit Risk

The Registrants monitor and manage counterparty credit risk through credit policies that include: (i) an established credit approval process; (ii) daily monitoring of counterparties' credit limits; (iii) the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting arrangements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risk surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Registrants seek to mitigate counterparty credit risk with a diversified portfolio of counterparties. The Registrants also have credit protection within various agreements to call on additional collateral support if and when necessary. Cash margin is collected and held to cover the credit risk of the counterparty until positions settle.

As of September 30, 2013, GenOn's counterparty credit exposure was $593 million and GenOn held collateral (cash and letters of credit) against those positions of $43 million, resulting in a net exposure of $550 million. Approximately 88% of GenOn's exposure before collateral is expected to roll off by the end of 2014. As of September 30, 2013, GenOn Americas Generation’s counterparty credit exposure was $582 million and GenOn Americas Generation held collateral (cash and letters of credit) against those positions of $43 million, resulting in a net exposure of $539 million. Approximately 88% of GenOn Americas Generation’s exposure before collateral is expected to roll off by the end of 2014. As of September 30, 2013, GenOn Mid-Atlantic’s counterparty credit exposure was $455 million and GenOn Mid-Atlantic held collateral (cash and letters of credit) against those positions of $43 million, resulting in a net exposure of $412 million. Approximately 91% of GenOn Mid-Atlantic’s exposure before collateral is expected to roll off by the end of 2014. Counterparty credit exposure is valued through observable market quotes and discounted at a risk free interest rate. The following tables highlight net counterparty credit exposure by industry sector and by counterparty credit quality. Net counterparty credit exposure is defined as the aggregate net asset position for the Registrants with counterparties where netting is permitted under the enabling agreement and includes all cash flow, mark-to-market, NPNS and non-derivative transactions. The exposure is shown net of collateral held and includes amounts net of receivables or payables.

Note 5 — Accounting for Derivative Instruments and Hedging Activities (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

This footnote should be read in conjunction with the complete description under Note 6, Accounting for Derivative Instruments and Hedging Activities, to the Registrants' 2012 Form 10-K.

Energy-Related Commodities (GenOn)

As of September 30, 2013, GenOn had energy-related derivative financial instruments extending through 2017.

Interest Rate Swaps (GenOn)

In 2010, NRG Marsh Landing entered into interest rate protection agreements (interest rate swaps) in connection with its project financing, which have been designated as cash flow hedges. NRG Marsh Landing entered into the interest rate swaps to reduce the risk with respect to the variability of the interest rates for term loans. On July 22, 2013, concurrent with the initial public offering of NRG Yield, Inc., GenOn sold its ownership interests in NRG Marsh Landing Holdings LLC to NRG Yield LLC, which included assuming the interest rate swap liability.

Volumetric Underlying Derivative Transactions (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

The following table summarizes the net notional volume buy/(sell) of the Registrants’ open derivative transactions broken out by commodity, excluding those derivatives that qualified for the NPNS exception as of September 30, 2013 and December 31, 2012.

Credit Risk Related Contingent Features (GenOn and GenOn Americas Generation)

Certain of GenOn and GenOn Americas Generation’s hedging agreements contain provisions that require the Registrants to post additional collateral if the counterparty determines that there has been deterioration in credit quality, generally termed "adequate assurance" under the agreements, or require the Registrants to post additional collateral if there were a one notch downgrade in the Registrants’ credit rating. The collateral required for contracts that have adequate assurance clauses that are in net liability positions as of September 30, 2013 was $27 million for GenOn and GenOn Americas Generation. The collateral required for contracts with credit rating contingent features that are in a net liability position as of September 30, 2013, was $0.4 million for GenOn and GenOn Americas Generation. In addition, GenOn and GenOn Americas Generation are parties to certain marginable agreements under which they have net liability positions, but the counterparties have not called for collateral due, which is approximately $2 million for GenOn and GenOn Americas Generation as of September 30, 2013. At September 30, 2013, GenOn Mid-Atlantic did not have any financial instruments with credit risk related contingent features.

See Note 4, Fair Value of Financial Instruments, for discussion regarding concentration of credit risk.

Note 6 — Debt (GenOn)

Redemption of Senior Unsecured Notes, Due 2014, or 2014 Senior Notes

In June 2013, GenOn redeemed all of the 2014 Senior Notes, with an aggregate outstanding principal amount of $575 million, at a redemption percentage of 106.778% of face value, as well, as any accrued and unpaid interest as of the redemption date. In connection with the redemption, an $11 million loss on the debt extinguishment of the 2014 Senior Notes was recorded during the three months ended June 30, 2013 which primarily consisted of a make whole premium payment offset by the write-off of unamortized premium.

NRG Marsh Landing Credit Agreement Term Conversion

In May 2013, NRG Marsh Landing met the conditions under the credit agreement to convert the construction loan for the facility to a term loan which will amortize on a predetermined basis. Prior to term conversion, NRG Marsh Landing drew the remaining funds available under the facility in order to pay costs due for construction. NRG Marsh Landing also issued a $26 million letter of credit under the facility in support of its debt service requirements. Concurrently with the term conversion, the $80 million cash collateralized letter of credit issued by GenOn Energy Holdings on behalf of NRG Marsh Landing in support of its collateral requirements under the PPA with PG&E was returned and the related letter of credit facility was terminated. On July 22, 2013, concurrent with the initial public offering of NRG Yield, Inc., GenOn sold its ownership interests in NRG Marsh Landing Holdings LLC to NRG Yield LLC, including the NRG Marsh Landing term loan.

Note 7 — Segment Reporting (GenOn and GenOn Americas Generation)

Prior to the NRG Merger, GenOn had the following segments: Eastern PJM, Western PJM/MISO, California, Energy Marketing and Other Operations. GenOn Americas Generation previously had the following segments: Eastern PJM, Northeast, California, Energy Marketing and Other Operations. In the fourth quarter of 2012, in conjunction with the NRG Merger, GenOn and GenOn Americas Generation began reporting the following segments: East, South Central, West and Corporate. All GenOn Mid-Atlantic entities are included within the GenOn East segment. There are distinct components with separate operating results and management structures for each segment, which are based on the geographical location of the power generation operations. GenOn and GenOn Americas Generation have recast the data from prior periods to reflect this change in reportable segments to conform to the current year presentation.

Note 8 — Income Taxes (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

GenOn

GenOn’s income tax (benefit)/expense consisted of the following:



	Successor		Predecessor		Successor		Predecessor
(In millions except otherwise noted)	Three months ended September 30, 2013		Three months ended September 30, 2012		Nine months ended September 30, 2013		Nine months ended September 30, 2012
Income/(loss) before income taxes	111		(81	)	(43	)	(337	)
Income tax expense/(benefit)	—		4		(6	)	8
Effective tax rate	—	%	(4.94	)%	13.95	%	(2.37	)%

GenOn

For the three and nine months ended September 30, 2013 and 2012, GenOn's overall effective tax rate was different than the statutory rate of 35% primarily due to a change in the valuation allowance. GenOn recorded an income tax expense or benefit which relates to changes in reserves for uncertain tax benefits for the periods presented.

Tax allocation — NRG will allocate taxes to GenOn Americas Generation and GenOn Mid-Atlantic, subsidiaries of GenOn using the pro rata method of income tax allocation as prescribed in ASC 740, Income Taxes. Electing to use the pro rata method requires presentation of a pro forma income statement for the most recent year and interim period reflecting a tax provision calculated on a separate return basis. Due to historical losses and the uncertainty surrounding the ability to generate future earnings, GenOn has recorded a full valuation allowance against its net deferred tax assets. Any change in the valuation allowance will be offset to the corresponding income tax expense or benefit. For the nine months ended September 30, 2013, GenOn recorded an income tax benefit relating to the reversal of the reserves for uncertain tax benefits. For the three and nine months ended September 30, 2012, GenOn recorded an income tax expense which related to reserves for uncertain tax benefits.

GenOn Americas Generation

GenOn Americas Generation and most of its subsidiaries are limited liability companies that are treated as branches of NRG Americas for income tax purposes. As a result, NRG Americas, GenOn and NRG have direct liability for the majority of the federal and state income taxes relating to GenOn Americas Generation's operations. Several of GenOn Americas Generation's subsidiaries exist as regarded corporate entities for income tax purposes. For the subsidiaries that continue to exist as corporate regarded entities, GenOn Americas Generation allocates current and deferred income taxes to each corporate regarded entity as if such entity were a single taxpayer utilizing the asset and liability method to account for income taxes. To the extent GenOn Americas Generation provides tax expense or benefit, any related tax payable or receivable to NRG is reclassified to equity in the same period since GenOn Americas Generation does not have a tax sharing agreement with NRG.

GenOn Americas Generation's allocated and pro forma income taxes resulting from its operations as of September 30, 2013 and December 31, 2012, are $0 as the income tax benefit and expense, respectively, relates to reserves for uncertain tax benefits attributable to its parent, GenOn.

GenOn Mid-Atlantic

GenOn Mid-Atlantic and GenOn Mid-Atlantic's subsidiaries are limited liability companies that are treated as branches of NRG Americas for income tax purposes. As a result, NRG Americas, GenOn and NRG have direct liability for the majority of the federal and state income taxes relating to GenOn Mid-Atlantic's operations. GenOn Mid-Atlantic’s allocated income taxes resulting from its operations are $0 for the three and nine months ended September 30, 2013 and 2012 as the income tax benefit and expense, respectively, relates to reserves for uncertain tax benefits which are attributable to its parent, GenOn. The pro forma income tax provision attributable to income before taxes is a tax expense of $36 million and tax benefit of $12 million during the three months ended September 30, 2013 and 2012, respectively. The pro forma income tax provision attributable to income before taxes for the nine months ended September 30, 2013 and 2012 is a tax expense of $32 million and a tax benefit of $6 million, respectively. The balance of GenOn Mid-Atlantic's pro forma deferred income taxes is a net deferred tax asset of $566 million and $598 million as of September 30, 2013 and December 31, 2012, respectively.

Note 9 — Related Party Transactions (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

Services Agreement with NRG (GenOn)

Subsequent to the NRG Merger, NRG provides GenOn with various management, personnel and other services, which include human resources, regulatory and public affairs, accounting, tax, legal, information systems, treasury, risk management, commercial operations, and asset management, as set forth in the Services Agreement. The initial term of the Services Agreement is through December 31, 2013, with an automatic renewal absent a request for termination. The fee charged is determined based on a fixed amount as described in the Services Agreement and was calculated based on historical GenOn expenses prior to the NRG Merger. The annual fees under the Services Agreement are approximately $193 million. NRG charges these fees on a monthly basis, less amounts incurred directly by GenOn. Management has concluded that this method of charging overhead costs is reasonable. For the three and nine months ended September 30, 2013, GenOn recorded costs related to these services of $37 million and $62 million, respectively, as selling, general and administrative — affiliate.

Administrative Services Provided by NRG for the Successor Period and Provided by GenOn Energy for the Predecessor Period

Prior to the NRG Merger, GenOn provided GenOn Americas Generation and GenOn Mid-Atlantic with various management, personnel and other services directly relating to their facilities. GenOn Americas Generation and GenOn Mid-Atlantic reimbursed GenOn for amounts equal to the costs of providing such services. In addition, GenOn's corporate overhead costs were allocated to its subsidiaries based on each operating subsidiary's planned operating expenses relative to all operating subsidiaries of GenOn. Subsequent to the NRG Merger, NRG provides GenOn Americas Generation and GenOn Mid-Atlantic with various management, personnel and other services consistent with those set forth in the Services Agreement discussed above between NRG and GenOn. GenOn's costs incurred under the Services Agreement with NRG are allocated to its subsidiaries based on each operating subsidiary's planned operating expenses relative to all operating subsidiaries of GenOn. These allocations and charges are not necessarily indicative of what would have been incurred had GenOn Americas Generation and GenOn Mid-Atlantic been unaffiliated entities. Management has concluded that this method of charging overhead costs is reasonable. Costs incurred by NRG and charged directly back to GenOn Americas and GenOn Mid-Atlantic are not considered to be affiliate costs for periods subsequent to the NRG Merger. Direct costs charged back to GenOn Americas Generation of $38 million for the three months ended September 30, 2012 and $117 million for the nine months ended September 30, 2012, were considered to be affiliate costs. Direct costs charged back to GenOn Mid-Atlantic of $24 million for the three months ended September 30, 2012 and $72 million for the nine months ended September 30, 2012, were considered to be affiliate costs.

The following costs were incurred under these arrangements:

The services include the bidding and dispatch of the generating units, fuel procurement and the execution of contracts, including economic hedges to reduce price risk. These transactions are recorded as operating revenues — affiliate or cost of operations — affiliate in GenOn Americas Generation's consolidated statements of operations. Amounts due from and to GenOn's indirect operating subsidiaries are recorded as accounts receivable — affiliate or accounts payables — affiliate. Substantially all energy marketing overhead expenses are allocated to GenOn's operating subsidiaries by GenOn Energy Management. For the three months ended September 30, 2013 and 2012, GenOn Americas Generation recorded a reduction to selling, general and administrative — affiliate of $2 million and $6 million, respectively, and for the nine months ended September 30, 2013 and 2012, GenOn Americas Generation recorded a reduction to selling, general and administrative — affiliate of $6 million and $18 million, respectively, related to the allocations of energy marketing overhead expenses to affiliates outside of GenOn Americas Generation.

GenOn Mid-Atlantic

GenOn Mid-Atlantic receives services from GenOn Energy Management which include the bidding and dispatch of the generating units, procurement of fuel and other products and the execution of contracts, including economic hedges, to reduce price risk. These transactions are recorded as operating revenues — affiliate or cost of operations — affiliate in GenOn Mid-Atlantic's consolidated statements of operations. Amounts due to and from GenOn Energy Management under the power, fuel supply and services agreements are recorded as accounts payables — affiliate or accounts receivables — affiliate. Under these agreements, GenOn Energy Management resells GenOn Mid-Atlantic's energy products in the PJM spot and forward markets and to other third parties. GenOn Mid-Atlantic pays the amount received by GenOn Energy Management for such capacity and energy.

At September 30, 2013 and December 31, 2012, no loans were outstanding under this credit agreement. In connection with the execution of the agreement, certain of GenOn's subsidiaries, as guarantors, entered into a guarantee agreement pursuant to which these guarantors guaranteed amounts borrowed and obligations incurred under the credit agreement. The credit agreement has a three year maturity and is payable at maturity, subject to certain exceptions primarily related to asset sales not in the ordinary course of business and borrowings of debt. In addition, the guarantors are restricted from incurring additional liens on their assets. At GenOn's election, the interest rate per year applicable to the loans under the credit agreement will be determined by reference to either (i) the base rate plus 2.50% per year or (ii) the LIBOR rate plus 3.50% per year. In addition, the credit agreement contains customary covenants and events of default.

Intercompany Cash Management Program (GenOn Americas Generation)

GenOn Americas Generation and certain of its subsidiaries participate in separate intercompany cash management programs whereby cash balances at GenOn Americas Generation and the respective participating subsidiaries are transferred to central concentration accounts to fund working capital and other needs of the respective participants. The balances under this program are reflected as notes receivable — affiliate or notes payable — affiliate, as appropriate. The notes are due on demand and accrue interest on the net position, which is payable quarterly, at the short term yield of the Federated Investors Treasury Obligation Fund or such other fund designated by GenOn Energy Holdings. At September 30, 2013 and December 31, 2012, GenOn Americas Generation had a net current note receivable from GenOn Energy Holdings of $299 million and $198 million, respectively, related to its intercompany cash management program. For the three and nine months ended September 30, 2013 and 2012, GenOn Americas Generation earned an insignificant amount of net interest income related to these notes.

Note 10 — Commitments and Contingencies (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

Contingencies

Set forth below is a description of the Registrants’ material legal proceedings. The Registrants believe that they have valid defenses to these legal proceedings and intend to defend them vigorously. The Registrants record reserves for estimated losses from contingencies when information available indicates that a loss is probable and the amount of the loss, or range of loss, can be reasonably estimated. In addition, legal costs are expensed as incurred. Management has assessed each of the following matters based on current information and made a judgment concerning its potential outcome, considering the nature of the claim, the amount and nature of damages sought, and the probability of success. Unless specified below, the Registrants are unable to predict the outcome of these legal proceedings or reasonably estimate the scope or amount of any associated costs and potential liabilities. As additional information becomes available, management adjusts its assessment and estimates of such contingencies accordingly. Because litigation is subject to inherent uncertainties and unfavorable rulings or developments, it is possible that the ultimate resolution of the Registrants’ liabilities and contingencies could be at amounts that are different from currently recorded reserves and that such difference could be material.

In addition to the legal proceedings noted below, the Registrants are parties to other litigation or legal proceedings arising in the ordinary course of business. In management's opinion, the disposition of these ordinary course matters will not materially adversely affect the Registrants’ respective consolidated financial position, results of operations, or cash flows.

Global Warming (GenOn)

In February 2008, the Native Village of Kivalina and the City of Kivalina, Alaska filed a suit in the U.S. District Court for the Northern District of California against GenOn and 23 other electric generating and oil and gas companies. The lawsuit sought damages of up to $400 million for the cost of relocating the village allegedly because of global warming caused by the greenhouse gas emissions of the defendants. In late 2009, the District Court ordered that the case be dismissed and the plaintiffs appealed. In September 2012, the U.S. Court of Appeals for the Ninth Circuit dismissed plaintiffs’ appeal. In October 2012, the plaintiffs petitioned for en banc rehearing of the case; which petition was denied in November 2012. In February 2013, plaintiffs filed a petition with the U.S. Supreme Court seeking review of the decision from the U.S. Court of Appeals. On May 20, 2013, the U.S. Supreme Court denied plaintiffs petition, thereby ending the case.

Actions Pursued by MC Asset Recovery (GenOn)

With Mirant Corporation's emergence from bankruptcy protection in 2006, certain actions filed by GenOn Energy Holdings and some of its subsidiaries against third parties were transferred to MC Asset Recovery, a wholly owned subsidiary of GenOn Energy Holdings. MC Asset Recovery is governed by a manager who is independent of NRG and GenOn. MC Asset Recovery is a disregarded entity for income tax purposes.

Under the remaining action transferred to MC Asset Recovery, MC Asset Recovery seeks to recover damages from Commerzbank AG and various other banks, or the Commerzbank Defendants, for alleged fraudulent transfers that occurred prior to GenOn Energy Holdings' bankruptcy proceedings. In December 2010, the U.S. District Court for the Northern District of Texas dismissed MC Asset Recovery's complaint against the Commerzbank Defendants. In January 2011, MC Asset Recovery appealed the United States District Court's dismissal of its complaint against the Commerzbank Defendants to the U.S. Court of Appeals for the Fifth Circuit. In March 2012, the U.S. Court of Appeals for the Fifth Circuit reversed the U.S. District Court's dismissal and reinstated MC Asset Recovery's amended complaint against the Commerzbank Defendants. If MC Asset Recovery succeeds in obtaining any recoveries from the Commerzbank Defendants, the Commerzbank Defendants have asserted that they will seek to file claims in GenOn Energy Holdings' bankruptcy proceedings for the amount of those recoveries. GenOn Energy Holdings would vigorously contest the allowance of any such claims. If the Commerzbank Defendants were to receive an allowed claim as a result of a recovery by MC Asset Recovery on its claims against them, GenOn Energy Holdings would retain from the net amount recovered by MC Asset Recovery an amount equal to the dollar amount of the resulting allowed claim.

Pending Natural Gas Litigation (GenOn)

GenOn is party to five lawsuits, several of which are class action lawsuits, in state and federal courts in Kansas, Missouri, Nevada and Wisconsin. These lawsuits were filed in the aftermath of the California energy crisis in 2000 and 2001 and the resulting FERC investigations and relate to alleged conduct to increase natural gas prices in violation of antitrust and similar laws. The lawsuits seek treble or punitive damages, restitution and/or expenses. The lawsuits also name as parties a number of energy companies unaffiliated with GenOn. In July 2011, the U.S. District Court for the District of Nevada, which is handling four of the five cases, granted the defendants’ motion for summary judgment and dismissed all claims against GenOn in those cases. The plaintiffs appealed to the U.S. Court of Appeals for the Ninth Circuit. The Ninth Circuit reversed the decision of the U.S. District Court for the District of Nevada. On August 26, 2013, GenOn along with the other defendants in the lawsuit filed a petition for certiorari to the U.S. Supreme Court challenging the Ninth Circuit’s decision. In September 2012, the State of Nevada Supreme Court, which is handling the remaining case, affirmed dismissal by the Eighth Judicial District Court for Clark County, Nevada of all plaintiffs’ claims against GenOn. In February 2013, the plaintiffs filed a petition for certiorari to the U.S. Supreme Court. On June 24, 2013, the U.S. Supreme Court denied the petition for certiorari, thereby ending one of the five lawsuits. GenOn has agreed to indemnify CenterPoint against certain losses relating to these lawsuits.

New Source Review Matters

The EPA and various states are investigating compliance of electric generating facilities with the pre-construction permitting requirements of the CAA known as “new source review.” Since 2000, the EPA has made information requests concerning the Avon Lake, Canal, Chalk Point, Cheswick, Conemaugh, Dickerson, Elrama, Keystone, Morgantown, New Castle, Niles, Portland, Potomac River, Shawville and Titus generating facilities. The Registrants continue to correspond with the EPA regarding some of these requests. The EPA agreed to share information relating to its investigations with state environmental agencies. In January 2009, GenOn received an NOV from the EPA alleging that past work at its Shawville, Portland and Keystone generating facilities violated regulations regarding new source review. In June 2011, GenOn received an NOV from the EPA alleging that past work at the Niles and Avon Lake generating facilities violated regulations regarding new source review.

In December 2007, the NJDEP sued GenOn in the U.S. District Court for the Eastern District of Pennsylvania, alleging that new source review violations occurred at the Portland generating facility. The suit sought installation of “best available” control technologies for each pollutant, to enjoin GenOn from operating the generating facility if it is not in compliance with the CAA and civil penalties. The suit also named past owners of the plant as defendants, but the claims against the past owners were dismissed. In March 2009, the Connecticut Department of Energy and Environmental Protection became an intervening party to the suit. GenOn believes that the work listed by the EPA and the work subject to the NJDEP suit were conducted in compliance with applicable regulations. In July 2013, the court entered a Consent Decree which generally requires the cessation of coal combustion at Portland Units 1 and 2 and the payment of $1 million to benefit the environment in New Jersey and Connecticut. The entry of the Consent Decree resolved this matter.

Cheswick Class Action Complaint (GenOn)

In April 2012, a putative class action lawsuit was filed against GenOn in the Court of Common Pleas of Allegheny County, Pennsylvania alleging that emissions from the Cheswick generating facility have damaged the property of neighboring residents. GenOn disputes these allegations. Plaintiffs have brought nuisance, negligence, trespass and strict liability claims seeking both damages and injunctive relief. Plaintiffs seek to certify a class that consists of people who own property or live within one mile of the plant. In July 2012, GenOn removed the lawsuit to the U.S. District Court for the Western District of Pennsylvania. In October 2012, the court granted GenOn’s motion to dismiss, which Plaintiffs appealed to the U.S. Court of Appeals for the Third Circuit. On June 25, 2013, the Third Circuit reversed the decision of the District Court. On September 3, 2013, GenOn filed a petition for rehearing with the Third Circuit which was subsequently denied on September 23, 2013. On October 15, 2013, GenOn filed a motion with the District Court seeking to stay the District Court case while it petitions for certiorari to the U.S. Supreme Court.

Cheswick Monarch Mine NOV (GenOn)

In 2008, the PADEP issued an NOV related to the Monarch mine located near the Cheswick generating facility. It has not been mined for many years. GenOn uses it for disposal of low-volume wastewater from the Cheswick generating facility and for disposal of leachate collected from ash disposal facilities. The NOV addresses the alleged requirement to maintain a minimum pumping volume from the mine. The PADEP indicated it will seek a civil penalty of approximately $200,000. GenOn contests the allegations in the NOV and has not agreed to such penalty. GenOn is currently planning capital expenditures in connection with wastewater from Cheswick and leachate from ash disposal facilities.

Ormond Beach Alleged Federal Clean Water Act Violations (GenOn)

In October 2012, the Wishtoyo Foundation, a California-based cultural and environmental advocacy organization, through its Ventura Coastkeeper Program, filed suit in the U.S. District Court for the Central District of California regarding alleged violations of the Clean Water Act associated with discharges of stormwater from the Ormond Beach generating facility. The Wishtoyo Foundation alleges that elevated concentrations of pollutants in stormwater discharged from the Ormond Beach generating facility were affecting adjacent aquatic resources in violation of (i) the Statewide General Industrial Stormwater permit (a general National Pollution Discharge Elimination System permit issued by the California State Water Resources Control Board that authorizes stormwater discharges from industrial facilities in California) and (ii) the state’s Porter-Cologne Water Quality Control Act. The Wishtoyo Foundation further alleged that GenOn had not implemented effective stormwater control and treatment measures and that GenOn had not complied with the sampling and reporting requirements of the General Industrial Stormwater permit. GenOn settled this matter in May 2013 and agreed to make operational changes and pay $79,000 in legal fees, $65,000 for supplemental environmental projects and $15,000 for monitoring costs.

Maryland Fly Ash Facilities

NRG MD Ash Management has three fly ash facilities in Maryland: Faulkner, Westland and Brandywine. NRG MD Ash Management disposes of fly ash from the Morgantown and Chalk Point generating facilities at Brandywine. NRG MD Ash Management disposes of fly ash from the Dickerson generating facility at Westland. NRG MD Ash Management no longer disposes of fly ash at the Faulkner facility. As described below, the MDE had sued NRG MD Ash Management and GenOn Mid-Atlantic regarding Faulkner, Brandywine and Westland. The MDE also had threatened not to renew the water discharge permits for all three facilities.

Faulkner Litigation. In May 2008, the MDE sued GenOn Mid-Atlantic and NRG MD Ash Management in the Circuit Court for Charles County, Maryland alleging violations of Maryland’s water pollution laws at Faulkner. The MDE contended that the operation of Faulkner had resulted in the discharge of pollutants that exceeded Maryland’s water quality criteria and without the appropriate NPDES permit. The MDE also alleged that GenOn failed to perform certain sampling and reporting required under an applicable NPDES permit. The MDE complaint requested that the court (i) prohibit continuation of the alleged unpermitted discharges, (ii) require GenOn to cease from further disposal of any coal combustion byproducts at Faulkner and close and cap the existing disposal cells and (iii) assess civil penalties. In July 2008, GenOn filed a motion to dismiss the complaint, arguing that the discharges are permitted by a December 2000 Consent Order. In January 2011, the MDE dismissed without prejudice its complaint and informed GenOn that it intended to file a similar lawsuit in federal court. In May 2011, the MDE filed a complaint against GenOn Mid-Atlantic and NRG MD Ash Management in the U.S. District Court for the District of Maryland alleging violations at Faulkner of the Clean Water Act and Maryland’s Water Pollution Control Law. The MDE contends that (i) certain of GenOn's water discharges are not authorized by the existing permit and (ii) operation of the Faulkner facility has resulted in discharges of pollutants that violate water quality criteria. The complaint asked the court to, among other things, (i) enjoin further disposal of coal ash; (ii) enjoin discharges that are not authorized by the existing permit; (iii) require numerous technical studies; (iv) impose civil penalties and (v) award MDE attorneys’ fees. GenOn disputed these allegations.

Brandywine Litigation. In April 2010, the MDE filed a complaint against GenOn Mid-Atlantic and NRG MD Ash Management in the U.S. District Court for the District of Maryland asserting violations at Brandywine of the Clean Water Act and Maryland’s Water Pollution Control Law. The MDE contended that the operation of Brandywine has resulted in discharges of pollutants that violate Maryland’s water quality criteria. The complaint requested that the court, among other things, (i) enjoin further disposal of coal combustion waste at Brandywine, (ii) require GenOn to close and cap the existing open disposal cells within one year, (iii) impose civil penalties and (iv) award MDE attorneys’ fees. In September 2010, four environmental advocacy groups became intervening parties in the proceeding.

Westland Litigation. In January 2011, the MDE informed GenOn that it intended to sue for alleged violations at Westland of Maryland’s water pollution laws, which suit was filed in the U.S. District Court for the District of Maryland in December 2012.

Permit Renewals. In March 2011, the MDE tentatively determined to deny NRG MD Ash Management's application for the renewal of the water discharge permit for Brandywine, which could result in a significant increase in operating expenses for the Chalk Point and Morgantown generating facilities. The MDE also had indicated that it was planning to deny GenOn’s applications for the renewal of the water discharge permits for Faulkner and Westland. Denial of the renewal of the water discharge permit for the latter facility could have resulted in a significant increase in operating expenses for GenOn Mid-Atlantic's Dickerson generating facility.

Settlement. In April 2013, NRG MD Ash Management and MDE signed a Consent Decree settling the disputes at each of the three ash facilities. GenOn agreed to pay a civil penalty of $1.9 million for alleged past violations and an additional $0.6 million (for agreed prospective penalties while GenOn implements the settlement). GenOn agreed to develop a technical solution which includes installing synthetic caps on the closed cells of each of the three ash facilities, for which $47 million has been reserved, and to remediate the sites. At this time, GenOn cannot reasonably estimate the upper range of its obligations for remediating the sites because GenOn has not (i) finished assessing each site including identifying the full impacts to both ground and surface water and the impacts to the surrounding habitat; (ii) finalized with the MDE the standards to which it must remediate; and (iii) identified the technologies required, if any, to meet the yet to be determined remediation standards at each site nor the timing of the design and installation of such technologies.

Purported Class Actions related to July 22, 2012 Announcement of NRG Merger Agreement (GenOn)

GenOn was named as a defendant in eight purported class actions in Texas and Delaware, related to its announcement of its agreement for NRG to acquire all outstanding shares of GenOn. These cases were consolidated into one state court case in each of Delaware and Texas and a federal court case in Texas. The plaintiffs generally alleged breach of fiduciary duties, as well as conspiracy, aiding and abetting breaches of fiduciary duties. Plaintiffs generally sought to: be certified as a class; enjoin the merger; direct the defendants to exercise their fiduciary duties; rescind the acquisition and be awarded attorneys' fees and costs and other relief that the court deems appropriate. Plaintiffs also demanded that there be additional disclosures regarding the merger terms. On October 24, 2012, the parties to the Delaware state court case executed a Memorandum of Understanding to resolve the Delaware purported class action lawsuit. In March 2013, the parties finalized the settlement of the Delaware action. On June 3, 2013, the court approved the Delaware class action settlement thereby ending the Delaware lawsuit. The remaining Texas state and federal court cases were dismissed in July 2013 and August 2013, respectively, thereby ending these matters.

Maryland Department of the Environment v. GenOn Chalk Point and GenOn Mid-Atlantic

In January 2013, Food & Water Watch, the Patuxent Riverkeeper and the Potomac Riverkeeper (together, Citizens Group) sent GenOn Mid-Atlantic a letter alleging that the Chalk Point, Dickerson and Morgantown generating facilities were violating the terms of three National Pollution Discharge Elimination System Permits by discharging nitrogen and phosphorous in excess of the limits in each permit. On March 21, 2013, the MDE sent GenOn Mid-Atlantic a similar letter with respect to the Chalk Point and Dickerson facilities, threatening to sue within 60 days if the facilities were not brought into compliance. On June 11, 2013, the Maryland Attorney General on behalf of the MDE filed a complaint in the U.S. District Court for the District of Maryland alleging violations of the Clean Water Act and Maryland environmental laws related to water. The lawsuit seeks injunctive relief and civil penalties in excess of $100,000.

Chapter 11 Proceedings (GenOn and GenOn Americas Generation)

In July 2003, and various dates thereafter, the Mirant Debtors filed voluntary petitions in the Bankruptcy Court for relief under Chapter 11 of the U.S. Bankruptcy Code. GenOn Energy Holdings and most of the other Mirant Debtors emerged from bankruptcy on January 3, 2006, when the Plan became effective. The remaining Mirant Debtors emerged from bankruptcy on various dates in 2007. Approximately 461,000 of the shares of GenOn Energy Holdings common stock to be distributed under the Plan have not yet been distributed and have been reserved for distribution with respect to claims disputed by the Mirant Debtors that have not been resolved. Upon the Mirant/RRI Merger, those reserved shares converted into a reserve for approximately 1.3 million shares of GenOn common stock. Upon the NRG Merger, those reserved shares converted into a reserve for approximately 159,000 shares of NRG common stock. Under the terms of the Plan, upon the resolution of such a disputed claim, the claimant will receive the same pro rata distributions of common stock, cash, or both as previously allowed claims, regardless of the price at which the common stock is trading at the time the claim is resolved. If the aggregate amount of any such payouts results in the number of reserved shares being insufficient, additional shares of common stock may be issued to address the shortfall.

Texas Franchise Audit (GenOn)

During the second quarter of 2013, GenOn settled the Texas Franchise tax dispute with the state relating to years 2001 through 2007. Prior to NRG Merger, the State of Texas issued franchise tax assessments against GenOn as a result of its audit indicating an underpayment of franchise tax of $72 million (including interest and penalties through June 30, 2013 of $29 million). These assessments relate primarily to a claim by Texas that would change the sourcing of intercompany receipts thereby increasing the amount of tax due. GenOn disagreed with most of the State's assessment and its determination and had accordingly accrued a portion of the liability but had protested the entire assessment. In June 2013, GenOn settled the matter with the State by agreeing to pay $11 million on issues arising from the audit, and reversed the remainder of the accrual. The reversal was recorded as a measurement period adjustment to the amounts recognized on the acquisition date.

Note 11 — Regulatory Matters (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

The Registrants operate in a highly regulated industry and are subject to regulation by various federal and state agencies. As such, the Registrants are affected by regulatory developments at both the federal and state levels and in the regions in which they operate. In addition, the Registrants are subject to the market rules, procedures, and protocols of the various ISO markets in which they participate. These power markets are subject to ongoing legislative and regulatory changes that may impact the Registrants.

In addition to the regulatory proceedings noted below, the Registrants are a party to other regulatory proceedings arising in the ordinary course of business or have other regulatory exposure. In management's opinion, the disposition of these ordinary course matters will not materially adversely affect the Registrants’ respective consolidated financial position, results of operations, or cash flows.

East Region (GenOn)

RMR Agreements for Elrama and Niles — In May 2012, GenOn filed with FERC an RMR rate schedule governing operation of unit 4 of the Elrama generating facility and unit 1 of the Niles generating facility. PJM determined that each of these units was needed past its planned deactivation date of June 1, 2012 to maintain transmission system reliability on the PJM system pending the completion of transmission upgrades. The RMR rate schedule sets forth the terms, conditions and cost-based rates under which GenOn operated the units for reliability purposes through September 30, 2012, the date PJM indicated the units would no longer be needed for reliability. In July 2012, FERC accepted GenOn's RMR rate schedule subject to hearing and settlement procedures. In the settlement discussions ordered by FERC, or in any subsequent hearing, GenOn's RMR rate schedule may be modified from that which was filed. The rates GenOn charged are subject to refund pending a ruling or settlement. GenOn filed a settlement of all outstanding issues in May 2013, which several parties are contesting. The matter is pending before FERC.

Note 12 — Environmental Matters (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

Environmental Capital Expenditures

Based on current rules, technology and plans based on proposed rules, GenOn estimates that environmental capital expenditures from 2013 through 2017 required to meet GenOn's regulatory environmental laws will be approximately $223 million for GenOn, which includes $56 million for GenOn Americas Generation. The amount for GenOn Americas Generation includes $6 million for GenOn Mid-Atlantic. These costs are primarily associated with controls to satisfy MATS at Conemaugh and NO_xcontrols for Sayreville and Gilbert. In addition, although GenOn expects to place Shawville in long-term protective layup and reactivation remains a technical possibility, GenOn does not expect to make any further investment in environmental controls for this facility. Reactivation after a long-term protective layup would likely involve numerous new permits and substantial additional investment. The Registrants continue to explore cost effective compliance alternatives to further reduce costs.

East Region

The EPA and various states are investigating compliance of electric generating facilities with the pre-construction permitting requirements of the CAA known as NSR. In January 2009, GenOn received an NOV from the EPA alleging that past work at Keystone, Portland and Shawville generating stations violated regulations regarding NSR. In June 2011, GenOn received an NOV from the EPA alleging that past work at Avon Lake and Niles generating stations violated NSR. In December 2007, the NJDEP filed suit alleging that NSR violations occurred at the Portland generating station, which was resolved pursuant to a July 2013 Consent Decree.

The MDE sued GenOn Mid-Atlantic and NRG MD Ash Management for alleged violations of water pollution laws at three fly ash disposal sites in Maryland: Faulkner (2008/2011), Brandywine (2010) and Westland (2012). On April 30, 2013, the court approved the consent decree resolving these issues. NRG MD Ash Management has since discontinued use of the Faulkner disposal site and opened a new, state of the art carbon burnout facility at the Morgantown plant that allows greater beneficial reuse (as a cement substitute).

For further discussion of these matters, refer to Note 10, Commitments and Contingencies.

Item 2 — MANAGEMENT'S NARRATIVE ANALYSIS OF THE RESULTS OF OPERATIONS AND FINANCIAL CONDITION (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

As you read this discussion and analysis, refer to the Registrants' Condensed Consolidated Financial Statements to this Form 10-Q, which present the results of operations for the three and nine months ended September 30, 2013 and 2012. Also, refer to the Registrants' 2012 Form 10-K, which includes detailed discussions of various items impacting the Registrants' business, results of operations and financial condition.

NRG Merger

On December 14, 2012, NRG completed the acquisition of GenOn. NRG issued, as consideration for the acquisition, 0.1216 shares of NRG common stock for each outstanding share of GenOn, including restricted stock units outstanding on the acquisition date, except for fractional shares which were paid in cash. See Note 3, NRG Merger, to the Condensed Consolidated Financial Statements.

The NRG Merger was accounted for by NRG using acquisition accounting and through the application of “push-down” accounting, the purchase price paid by NRG was allocated to the Registrants' assets, liabilities and equity as of the acquisition date based upon preliminary estimates. Accordingly, the successor financial statements reflect a new basis of accounting and predecessor and successor period financial results are presented, but not comparable.

The most significant impacts of the new basis of accounting during the successor periods were (i) reduced depreciation expense due to the step-down of depreciable assets, (ii) lower interest expense for the remaining life of long-term debt due to its revaluation and related debt premium amortization along with the repayment of the senior secured term loan due 2017, and (iii) reduced cost of operations due to the amortization of lease obligations and out-of-market contracts.

The results of operations for successor periods included herein reflect certain acquisition-related transaction and integration costs which are not expected to have a continuing impact on the results going forward, and those amounts are included within a separate line within the Registrants' consolidated results of operations.

Predecessor and Successor Reporting

As a result of the impact of pushdown accounting, the financial statements and certain note presentations separate each of the Registrants' presentations into two distinct periods, the period before the consummation of the NRG Merger (labeled predecessor) and the period after that date (labeled successor), to indicate the application of different basis of accounting between the periods presented.

Environmental Matters

The Registrants are subject to a wide range of environmental regulations in the development, ownership, construction and operation of projects. These laws and regulations generally require that governmental permits and approvals be obtained before construction and during operation of power plants. Environmental regulations have become increasingly stringent and the Registrants expect this trend to continue. The electric generation industry is likely to face new requirements to address various emissions, including greenhouse gases, as well as combustion byproducts, water discharge and use, and threatened and endangered species. In general, future laws and regulations are expected to require the addition of emissions controls or other environmental quality equipment or the imposition of certain restrictions on the operations of the Registrants' facilities, which could have a material effect on the Registrants' operations. Complying with environmental requirements involves significant capital and operating expenses. The Registrants decide to invest capital for environmental controls based on relative certainty of the requirements, an evaluation of compliance options, and the expected economic returns on capital. See Note 10, Commitments and Contingencies, and Note 12, Environmental Matters, to the Condensed Consolidated Financial Statements for further discussion.

East Region

RGGI — In February 2013, RGGI, Inc. released a proposed model rule that if promulgated by the nine RGGI member states, would reduce the CO₂ emissions cap from 165 million tons to 91 million tons in 2014 with a 2.5% reduction each year from 2015 to 2020. Each of the RGGI member states has published a proposed rule. Each of the RGGI states may finalize these regulations later this year. If this occurs, the Registrants expect earnings at their plants in Massachusetts, New York, and particularly those in Maryland, to be negatively affected. The extent to which they would be negatively affected depends on the price of the CO₂ emissions allowances, which in turn will be significantly influenced by future natural gas prices, power prices, generation resource mix, dispatch order, and any nuclear plant retirements.

Regulatory Matters

As operators of power plants and participants in wholesale energy markets, certain of the Registrants' entities are subject to regulation by various federal and state government agencies. These include the Commodities Futures Trading Commission and FERC, as well as other public utility commissions in certain states where the Registrants' generating assets are located. In addition, the Registrants are subject to the market rules, procedures and protocols of the various ISO markets in which they participate. The Registrants must also comply with the mandatory reliability requirements imposed by NERC and the regional reliability entities in the regions where they operate.

East Region

New York

NYSPSC Order Rescinding Danskammer Retirement — On October 29, 2013, the NYSPSC took emergency action to rescind its approval for the 530 MW Danskammer facility to retire on October 30, 2013. The NYSPSC’s stated goal was to allow the facility to return to service in order to constrain rate increases in New York. The return to service of this facility may affect capacity prices received by NRG for its resources in the Rest-of-State capacity zone and the Lower Hudson Valley capacity zone.

PJM

Minimum Offer Price Rule, or MORP, Litigation — On April 12, 2011, FERC issued an order addressing a complaint filed by PJM Power Providers Group seeking to require PJM to address the potential adverse impacts of out-of-market generation on the PJM Reliability Pricing Model, capacity market, as well as PJM's subsequent submission seeking revisions to the capacity market design, in particular the MOPR. In its order, FERC generally strengthened the MOPR and the protections against market price distortion from out-of-market generation. On November 17, 2011, FERC largely denied rehearing of its April 12, 2011 order. Several parties have appealed FERC's decision to federal court, and those appeals have been consolidated in the Third Circuit Court of Appeals. Oral arguments were held on September 10, 2013. The outcome of this proceeding could drive future capacity prices.

MOPR Revisions — On December 7, 2012, PJM filed comprehensive revisions to its MOPR rules at FERC. On May 2, 2013, FERC accepted PJM's proposal in part, and rejected it in part. Among other things, FERC approved the portions of the PJM proposal that exempt many new entrants from MOPR rules, including projects proposed by merchant generators, public power entities and certain self-supply entities. This exemption is subject to certain conditions designed to limit the financial incentive of such entities to suppress market prices. However, FERC rejected PJM's proposal to eliminate the unit specific review process, and instead directed PJM to continue allowing units to demonstrate their actual costs and revenues, and bid into the auction at that price. On June 3, 2013, NRG filed a request for rehearing of the FERC order and subsequently protested the manner in which PJM proposed to implement the FERC order. These challenges are both pending.

New Jersey's Long-Term Capacity Agreement Pilot Program — In 2011, the New Jersey Board of Public Utilities, or NJBPU, awarded New Jersey Power Development LLC, a subsidiary of NRG, a Standard Offer Capacity Agreement, or SOCA, with each of the four New Jersey electric utilities with respect to the proposed Old Bridge facility as part of New Jersey's Long-Term Capacity Agreement Pilot Program.

The constitutionality of the SOCAs awarded by the NJBPU to NRG and other entities were challenged in the U.S. District Court for the District of New Jersey. On October 11, 2013, the New Jersey Federal Court held that the SOCAs violated the Supremacy Clause of the U.S. Constitution because they intruded on the authority Congress had granted to FERC under the Federal Power Act to set wholesale energy prices, which authority FERC had expressed through the PJM capacity auction. Additionally, the Court found that the SOCA poses an obstacle to FERC’s implementation of the PJM capacity auction. Based on these findings, the New Jersey Federal Court found the SOCAs to be null and void.

In a similar challenge lodged in the U.S. District Court for the District of Maryland against a comparable long-term contract issued to a generator in Maryland by the Public Service Commission of Maryland, the Maryland Court ruled on September 30, 2013, the Maryland contract violated the Supremacy Clause of the U.S. Constitution and was preempted. The Court based this holding on its finding that the compensation under the Maryland contract amounted to the PSC effectively setting the wholesale price when Congress had vested that authority in FERC, thus preempting state regulatory action to establish the wholesale price.

New England (GenOn and GenOn Americas Generation)

New England Power Generators Association, or NEPGA, Complaint — On May 17, 2013, the NEPGA filed a complaint against ISO New England, Inc., or ISO-NE, asking FERC to clarify that under ISO-NE's existing tariff, a capacity resource's inability to procure or schedule fuel when called upon is not a tariff violation or an attempt to manipulate the ISO-NE energy markets. On August 27, 2013, FERC granted the complaint after making a distinction between being unable to procure fuel or transportation and making an economic determination not to do so. FERC found that if a capacity resource cannot procure fuel or transportation when called upon, then the resource is not physically available and may be excused for non-performance. As an operator of gas fired generation facilities in New England, the Company could have been subject to sanction when gas is not available, had FERC not granted the NEPGA complaint.

West Region (GenOn and GenOn Americas Generation)

The California Independent System Operator, or CAISO, and California Public Utilities Commission, or CPUC, launched a joint stakeholder initiative to develop a multiyear reliability market framework. In a whitepaper issued on July 10, 2013, the CAISO/CPUC proposed a joint reliability framework that combined multi-year resource adequacy obligations for Load Serving Entities with a multi-year market-based CAISO backstop capacity procurement mechanism. Specifically, the proposal (i) retains the current one-year forward system and local capacity procurement obligations and extends those procurement obligations to system, local and flexible capacity for two and three years forward; (ii) develops a CAISO-run capacity auction; and (iii) provides for an annual long-term reliability planning assessment focusing on the four to ten-year forward period. The CAISO and CPUC held a joint workshop to discuss the proposal on July 17, 2013, and stakeholders, including NRG, filed comments on the proposal on July 25, 2013. While the whitepaper lacks specificity, GenOn and GenOn Americas Generation view any attempt to extend the procurement obligations forward, and adopt a market structure to help meet those obligations, as a potentially positive step.

South Central Region (GenOn)

On July 5, 2013, AmerenEnergy Resources Generating Company, or Ameren, filed a complaint against MISO pertaining to the compensation for generators asked by MISO to provide service past their retirement date due to reliability concerns. Ameren asked FERC to require MISO to provide such generators their full cost of service as compensation and not merely cover the generator's incremental costs of operation going-forward costs. GenOn supports the Ameren complaint. The matter remains pending.

New and On-going Company Initiatives

Operational Improvement Activities

NRG has announced its intention to continue operations at the Avon Lake and New Castle facilities, which are currently in operation and had been scheduled for deactivation in April 2015. NRG intends to add natural gas capabilities at these facilities, which is expected to be completed by the summer of 2016. Additionally, NRG has accelerated the deactivation of the Portland and Titus facilities to 2014 and 2013, respectively.

Mark-to-market for Economic Hedging Activities

Mark-to-market for economic hedging activities includes asset-backed hedges that have not been designated as cash flow hedges. Total net mark-to-market results increased by $264 million and $17 million for the three and nine months ended September 30, 2013, respectively, compared to the same periods in 2012.

The breakdown of gains and losses included in operating revenues and operating costs and expenses are as follows:

Mark-to-market results consist of unrealized gains and losses. The settlement of these transactions is reflected in the same caption as the items being hedged.

For the nine months ended September 30, 2013, the loss in operating revenues from economic hedge positions was driven by the reversal of previously recognized unrealized gains from electricity and natural gas contracts that settled during the period slightly offset by an increase in the value of forward sales of electricity and natural gas contracts as a result of decreases in forward power and natural gas prices. The gain in operating costs and expenses from economic hedge positions was driven by the reversal of previously recognized unrealized losses from fuel contracts that settled during the period partially offset by a decrease in the value of forward purchases of fuel contracts as a result of decreases in forward fuel prices.

For the nine months ended September 30, 2012, the loss in operating revenues from economic hedge positions was driven by the reversal of previously recognized unrealized gains from electricity and natural gas contracts that settled during the period slightly offset by an increase in the value of forward sales of electricity and natural gas contracts as a result of decreases in forward power and natural gas prices. The loss in operating costs and expenses from economic hedge positions was driven by a decrease in the value of forward purchases of fuel contracts, primarily as a result of decreases in forward coal prices. The loss was partially offset by the reversal of previously recognized unrealized losses from fuel contracts that settled during the period.

In accordance with ASC 815, the following table represents the results of GenOn's financial and physical trading of energy commodities.

Based on this evaluation, the Registrants’ principal executive officer, principal financial officer and principal accounting officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report on Form 10-Q.

Changes in Internal Control over Financial Reporting

The Registrants continue to integrate certain business operations, information systems, processes and related internal control over financial reporting as a result of the NRG Merger. The Registrants will continue to assess the effectiveness of internal control over financial reporting as merger integration activities continue.

PART II

OTHER INFORMATION

Item 1 — LEGAL PROCEEDINGS (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

For a discussion of material legal proceedings in which the Registrants were involved through September 30, 2013, see Note 10, Commitments and Contingencies, to this Form 10-Q.

Item 1A — RISK FACTORS (GenOn, GenOn Americas Generation and GenOn Mid-Atlantic)

Information regarding risk factors appears in Part I, Item 1A, Risk Factors, in the Registrants' 2012 Form 10-K. Except as presented below, there have been no material changes in the Registrants' risk factors since those reported in its 2012 Form 10-K.

Policies at the national, regional and state levels to regulate GHG emissions, as well as climate change, could adversely impact the Registrants' results of operations, financial condition and cash flows.

The impact of further legislation or regulation of GHGs on the Registrants' financial performance will depend on a number of factors, including the level of GHG standards, the extent to which mitigation is required, the applicability of offsets, and the extent to which the Registrants would be entitled to receive CO₂ emissions credits without having to purchase them in an auction or on the open market.

The Registrants operate generating units in Maryland, Massachusetts, and New York that are subject to RGGI, which is a regional cap and trade system. In February 2013, RGGI, Inc. released a model rule that if adopted by the member states would reduce the number of allowances available and potentially increase the price of each allowance. Each of these states has proposed a rule that would reduce the number of allowances, which the Registrants believe would increase the price of each allowance. If adopted, the proposed rule could adversely impact the Registrants' results of operations, financial condition and cash flows.

The California CO₂ cap and trade program for electric generating units greater than 25 MW commenced in 2013. The impact on the Registrants depends on the cost of the allowances and the ability to pass these costs through to customers.

GHG emissions from power plants are regulated under various section of the Clean Air Act. In 2012, EPA proposed stringent standards for GHG emissions from certain new fossil-fueled electric generating units (simple-cycle CTs are not covered). The proposed standard is in effect until the rule is finalized or re-proposed. EPA has released a pre-publication version of its re-proposed rule for new units, which the Registrants expect will be published in the fourth quarter of 2013. The re-proposal is expected to include simple cycle CTs that exceed a certain capacity factor and is expected to create a different but still stringent standard for coal-fired units. The Company expects EPA to issue another rule that will require states to develop CO₂ standards that would apply to existing fossil-fueled generating facilities at some future date. This rule could adversely impact the Registrants' results of operations, financial condition and cash flows.

Hazards customary to the power production industry include the potential for unusual weather conditions, which could affect fuel pricing and availability, the Registrants' route to market or access to customers, i.e., transmission and distribution lines, or critical plant assets. To the extent that climate change contributes to the frequency or intensity of weather related events, the Registrants' operations and planning process could be impacted.
