Item 8.01  Other Events

     NRG Energy, Inc., or NRG, is preparing to file a registration statement on Form S-3 to register senior debt securities, unsecured debt securities, preferred stock and common stock, the issuance of which are together referred to as the Financing Transactions. The Financing Transactions will be entered into to finance the Acquisition (described below) and re-capitalize the Company. In connection with this registration statement, NRG is filing the unaudited pro forma analyses as set forth below.

     On September 30, 2005, NRG entered into an Acquisition Agreement (the “Acquisition Agreement”) with Texas Genco LLC, a Delaware limited liability company (“Texas Genco”), and each of the direct and indirect owners of Texas Genco (the “Sellers”). Pursuant to the Acquisition Agreement, upon the terms and subject to the conditions set forth therein, the Company agreed to purchase all of the outstanding equity interests in Texas Genco (the “Acquisition”). We expect to close this transaction during the first quarter of 2006.

     On a pro forma basis, we estimate that the total purchase price will be $6.121 billion. This amount is comprised of common stock, cash, preferred stock and capitalized expenses. The number of shares to be issued to the Sellers is 35,406,320, of this amount 19,346,788 are from treasury and 16,059,532 are newly issued shares, at a price of $45.37 which is the average NRG share price immediately before and after the pro forma date of closing, or September 30, 2005, with a total value of $1.6 billion for the shares. NRG will pay $4.031 billion in cash, issue Cumulative Redeemable Preferred Stock (the “Cumulative Preferred Stock”) at a value of $368 million and will capitalize expenses of $120 million. This purchase price includes the assumption by the Company of approximately $2.74 billion of Texas Genco indebtedness. As a result of the Acquisition, Texas Genco will become a wholly owned subsidiary of the Company.

     Of the pro forma $6.121 billion consideration to the Sellers upon consummation of the Acquisition, the Company is paying $4.031 billion in cash, and must issue a minimum of 35,406,320 shares of the Company’s common stock. At the Company’s election, the remaining consideration with a fair value of $368 million may be comprised of either an additional 9,038,125 shares of common stock, additional cash, shares of a new series of NRG’s Cumulative Preferred Stock or a combination of the foregoing. If issued, the aggregate liquidation preference of the Cumulative Preferred Stock will be equal to the average trading value of 9,038,125 shares of the Company’s common stock over a twenty trading day period prior to closing. If the Company elects to pay all or a portion of the remaining purchase price in cash, the amount payable in cash would be calculated in the same manner. On a pro forma basis we have assumed that the remaining consideration will be paid by issuing the Cumulative Preferred Stock. Thus, our interest expense increased on a pro forma basis for the Cumulative Preferred Stock. Interest expense increased by $41.4 million for the year ended December 31, 2004 and by $33.1 million for the nine months ended September 30, 2005. If we would elect to pay this consideration in cash or common stock, our income from continuing operations before tax would increase by these amounts, respectively.

     If less than $200 million of aggregate liquidation preference of the Cumulative Preferred Stock is issued in the Acquisition, and the Company elects to issue the Cumulative Preferred Stock, then the initial dividend rate on the Cumulative Preferred Stock will be 9%. If more than $200 million of aggregate liquidation preference is issued, then the initial dividend rate on the Cumulative Preferred Stock will be 10%. In either case, the applicable dividend rate will increase by 1% per quarter to a maximum of 2% above the initial dividend rate. The Cumulative Preferred Stock will be redeemable at the option of the Company at any time for cash and will be mandatorily redeemable by the Company on the earlier of seven and one-half years from issuance and a change of control of the Company. On a pro forma basis we have calculated the dividend rate assuming the initial dividend rate is 10%, increasing to 12% after two quarters.

     NRG expects to finance the cash requirements of the Acquisition through a combination of a new senior secured credit facility, an unsecured high yield notes offering and the sale of common and preferred equity securities in the public markets. We have received a commitment letter from Morgan Stanley Senior Funding, Inc. (“Morgan Stanley”) and Citigroup Global Markets, Inc. (“Citigroup”) to provide us with up to $4.8 billion in senior secured debt financing, including up to $3.2 billion under a senior first priority term loan facility, up to $1 billion under a senior first priority secured revolving credit facility and up to $1 billion under a senior first priority secured synthetic letter of credit facility. The commitment letter further provides for up to $5.1 billion in bridge financing to fund all necessary amounts not provided for under the senior secured debt financing. NRG does not intend to draw down on the bridge financing unless the contemplated high yield debt financing and preferred and common equity financings are for some reason unavailable at the time of the closing. The commitment letter is subject to customary conditions to consummation, including the absence of any event or circumstance that would have a material adverse effect on the business, assets, properties, liabilities, condition (financial or otherwise) or results of operations, taken as a whole, of Texas Genco, or Texas Genco and NRG combined, since June 30, 2005. We have agreed to pay Morgan Stanley and Citigroup $44.6 million in connection with the commitment letter, or the Bridge Loan Commitment Fee, and have agreed to indemnify Morgan Stanley and Citigroup against certain liabilities.

     The Financing Transactions will enable us to refinance our outstanding Second Priority Notes and Credit Facility. This Credit Facility includes a senior secured term loan, a revolving credit facility and funded letter of credit facility. In addition, the new financing will supply the source of funds to acquire Texas Genco and to repay their Term Loan Facility and Senior Notes. The following is a brief summary of the companies’ outstanding debt instruments that we expect to refinance with the new debt structure:

	Old Debt Structure
	As of September 30, 2005				New Debt		New Debt
(in millions)	NRG		Texas Genco		Structure		Term
Term loan – adjustable interest		447		1,614		3,200		7 years
Second Priority Notes		1,080		n/a		n/a		n/a
Unsecured senior notes		n/a		1,125		3,600		7 years
Revolving credit facility		150		325		1,000		5 years
Funded letter of credit facility		350		694		n/a		n/a
Synthetic letter of credit facility		n/a		n/a		1,000		5 years

     On a pro forma basis we have assumed that the fixed interest rate for the new unsecured senior notes will be 7.25%. For the new term loan facility we have assumed that the adjustable annual interest rate will be 6.504% for the year ended December 31, 2004 and 6.622% for the nine months ended September 30, 2005. NRG will pay an annual fee of 0.5% for the new revolving credit facility, and when drawn upon, the adjustable interest rate would be the London Interbank Offering Rate plus 2%. On a pro forma basis, we have assumed an annual fee of 2% to have access to the synthetic letter of credit facility.

     On December 8, 2005 NRG entered into an Asset Purchase and Sale Agreement to sell all the assets of NRG Audrain Generating LLC, or Audrain, to AmerenUE, a subsidiary of Ameren Corporation. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation. The purchase price is $115 million, subject to customary purchase price adjustments. The transaction is expected to close during the first half of 2006. The sale is subject to customary approvals, including Federal Energy Regulatory Commission, Missouri Public Utilities Commission, Illinois Commerce Commission, and Hart-Scott-Rodino review. We expect to record a gain of approximately $15 million at closing.

     On May 19, 2005, pursuant to the exercise of a right of first refusal by Texas Genco, subsequent to a third party offer to American Electric Power, or AEP, in early 2004, Texas Genco acquired from AEP an additional 13.2% undivided interest in South Texas Project, or STP. We refer to that acquisition as the “ROFR.” As a result, Texas Genco now owns a 44.0% undivided interest in STP. For pro forma purposes, NRG has accounted for the ROFR as a business acquisition and included the ROFR in our pro forma adjustments to the statements of operation.

Transactional Pro Forma Analysis:

     The following tables present historical condensed consolidated financial information of (i) NRG for the year ended December 31, 2004 and as of and for the nine months ended September 30, 2005, (ii) Texas Genco for the year ended December 31, 2004 and as of and for the nine months ended September 30, 2005, and (iii) the combined company on a pro forma basis for the year ended December 31, 2004 and as of and for the nine months ended September 30, 2005. The combined company on a pro forma basis is shown after giving effect to (a) the reclassification of Audrain as a discontinued operation; (b) the inclusion of the results pursuant to the ROFR; (c) the refinancing of NRG’s old debt structure; and (d) the remaining financing and subsequent Acquisition.

     The historical consolidated financial information of NRG for the year ended December 31, 2004 is derived from the historical financial information contained in the audited consolidated financial statements of NRG incorporated by reference in this current report Form 8-K. The unaudited historical consolidated financial information as of and for the nine months ended September 30, 2005 (i) have been derived from NRG’s unaudited condensed consolidated financial statements which are incorporated by reference in this current report Form 8-K, (ii) have been prepared on a similar basis to that used in the preparation of the audited financial statements, and (iii) in the opinion of NRG’s management, include all adjustments necessary for a fair statement of the results for the unaudited interim period.

     The historical consolidated financial information for Texas Genco as of December 31, 2004 were derived from the audited consolidated financial statements of Texas Genco LLC as of December 31, 2004 and the audited consolidated financial statements of Texas Genco Holdings, Inc. as of December 31, 2004, and are included as Exhibits 99.02 and 99.03 to this current report Form 8-K. The historical consolidated financial information for Texas Genco as of and for the nine months ended September 30, 2005 (i) were derived from unaudited financial statements of Texas Genco LLC for the nine months ended September 30, 2005 and the unaudited financial statements of Texas Genco Holdings, Inc. for the period from January 1, 2005 through April 13, 2005 (on April 13, 2005 the remaining business of Texas Genco Holdings, Inc. was acquired by Texas Genco LLC) included as Exhibit 99.01 to this current report Form 8-K, (ii) have been prepared on a similar basis to that used in the preparation of the aforementioned audited financial statements and, (iii) in the opinion of Texas Genco’s management, include all adjustments necessary for a fair presentation of the results for the unaudited interim period.

     The unaudited pro forma combined income statement data and other financial and operating data for the combined company for the year ended December 31, 2004 and for the nine months ended September 30, 2005 give effect to (a) the reclassification of Audrain as a discontinued operation; (b) the inclusion of the results pursuant to the ROFR; (c) the refinancing of NRG’s old debt structure; and (d) the remaining financing and subsequent Acquisition as if they had occurred on January 1, 2004. The unaudited pro forma combined balance sheet data as of September 30, 2005 gives effect to (a) the sale of Audrain as of September 30, 2005; (b) the refinancing of NRG’s old debt structure; and (c) the remaining financing and subsequent Acquisition as if they had occurred on September 30, 2005. The combined unaudited pro forma financial data presented below do not purport to represent what the combined company’s results of operations would actually have been had the Financing Transactions and the Acquisition in fact occurred on the dates specified above or to project the combined company’s results of operations for any future period.

     The historical consolidated financial information and the unaudited pro forma combined financial information set forth below should be read in conjunction with the consolidated financial statements of NRG Energy, Inc., the related notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operation included in NRG Energy, Inc.’s annual report on Form 10-K for the year ended December 31, 2004 as amended by the Current Report on Form 8-K filed on December 20, 2005, and quarterly report on Form 10-Q for the nine months ended September 30, 2005 and the consolidated financial statements of Texas Genco LLC and Texas Genco Holdings, Inc., the related notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operation for the year ended December 31, 2004 and for the nine months ended September 30, 2005 filed and incorporated herein by reference as Exhibits 99.01, 99.02 and 99.03 to this current report on Form 8-K.

     The Acquisition will be accounted for using the purchase method of accounting and, accordingly, the purchase price will be allocated to the assets acquired and liabilities assumed based on the estimated fair value of such assets and liabilities at the date of acquisition. As it is difficult to estimate a pro forma allocation of purchase price without completed asset appraisals, we have made a preliminary allocation estimate based on the latest available information. For purposes of these pro forma statements we have assumed that the consideration paid in excess of the historical book value of net assets acquired is related to the step-up in fair value of Texas Genco’s emission credit inventory, a step-up in the value of Texas Genco’s fixed assets, and an increase in liabilities for assumed out-of-market contracts. Once the Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices, and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

     The following summarizes the estimated pro forma purchase price and allocation impact of the Acquisition on NRG’s financial statements at September 30, 2005:

		(in millions)
Cash paid to Sellers		$	4,031
Fair value of 10% Mandatorily Redeemable Preferred Stock issued to Sellers			368
NRG common stock issued to Sellers2			1,606
Fees and transaction costs
Fees for early repayment of existing Texas Genco debt	99
Investment banker fees	17
Total capitalized acquisition expenses			116
Total pro forma Purchase Price			6,121
Purchase price allocation:
Net book value of Texas Genco assets and liabilities acquired			773
Write-off of Texas Genco deferred financing fees			(109	)
Step-up in fixed assets			4,943
Step-up in emission credit inventory			1,309
Increase in out-of-market contracts1			(2,506	)
Elimination of Texas Genco goodwill			(791	)
Increase in current deferred tax assets			391
Increase in non-current deferred tax liabilities			(260	)
NRG goodwill			2,371
Total allocated		$	6,121

1	Assuming the acquisition had occurred at September 30, 2005, a number of energy and gas sale contracts initiated by Texas Genco were considered to be out-of-the-money and consequently, NRG would have to recognize a liability for these contracts at Acquisition. The fair value of these contracts was assessed based on forecasted energy prices that were calculated as of the pro forma acquisition date.
	A number of these contracts have already been recorded as a liability by Texas Genco. At Acquisition, we will increase this liability by an additional $2.5 billion to a total fair value of $3.4 billion. The lives of these contracts extend until the end of 2010, however, approximately 91% of the value of these contracts extend until the end of 2008 only. The approximate amortization of these liabilities for the fiscal year of 2006 is $1.3 billion, for the fiscal year of 2007 is $1.1 billion and for the fiscal year of 2008 is $0.7 billion.
2	The Company will issue a minimum of 35,406,320 shares of its common stock. At the Company's election, the remaining consideration may be comprised of either an additional 9,038,125 shares of common stock, additional cash, shares of a new series of NRG's Cumulative Preferred Stock or a combination. The value of this remaining consideration will be equal to the average trading value of 9,038,125 shares of the Company's common stock over a twenty day trading period prior to closing.

Footnotes to Pro Forma Combined Balance Sheet as of September 30, 2005

(1) On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with AmerenUE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation. The purchase price is $115 million, and the expected gain for the sale of Audrain is approximately $15 million before tax.

I. Refinancing of NRG’s Long-Term Debt

(2) Reflects the proceeds from new debt issued by NRG for refinancing purposes and the payment to retire NRG existing debt:

Payment to retire NRG’s existing term loan	$	(446,625	)
Payment to retire NRG’s existing Second Priority Notes		(1,080,412	)
Payment to retire NRG’s existing revolver balance		(80,000	)
Payment of accrued interest for NRG’s old debt structure		(25,376	)
Refinancing portion of proceeds from issuing the new term loan		446,625
Refinancing portion of proceeds from issuing the new unsecured senior notes		1,080,412

Net book value of Texas Genco assets and liabilities acquired				773,112
Write-off of Texas Genco deferred financing fees				(109,339	)

inventory and goodwill. Once the Acquisition is closed, the purchase price and allocation may change significantly from the pro forma amounts included herein based on the results of appraisals, changes in market prices, the purchase price and allocation to net assets acquired and liabilities assumed and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

Footnotes to Pro Forma Combined Statement of Operations for the Nine Months Ended September 30, 2005

(1)	The Pro Forma Combined Texas Genco LLC Statement of Operations for the Nine Months Ended September 30, 2005 can be found in Exhibit 99.10.
(2)	On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with Ameren UE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation.
(3)	Reflects pro forma results of additional 13.2% interest in STP acquired in the ROFR for the period from January 1, 2005 until ROFR acquisition date on May 19, 2005.
(4)	Reflects the reversal of interest expense associated with NRG’s existing debt structure, prior to the acquisition of Texas Genco and the recording of interest expenses associated with the new debt structure:

Reversal of interest expense associated with NRG’s existing debt structure	$	108,782
Interest expense associated with the refinancing of NRG’s debt		(84,471	)
Total	$	24,311

(5)	Reflects the tax effect of both the pro forma adjustments (pro forma effective tax rate of 39.5%) and Texas Genco’s pass-through earnings (pro forma effective tax rate of 34.5% - the difference in tax rates is due to a 0% state corporate income tax rate for Texas Genco in the state of Texas), which will now generate taxable income for the combined entity.
(6)	Reflects the increase in revenue due to the amortization of the out-of-money contracts recorded for the Acquisition of Texas Genco 2.
(7)	Reflects the reversal of Management Fees of $7.5 million which will not be applicable following the Acquisition and the additional amortization expense for emission credits of $91.5 million based on the amount of credits used during this period by Texas Genco.
(8)	Reflects the increase in depreciation expense due to the step-up in the value of fixed assets at the Acquisition of Texas Genco2.

Due to the lack of asset appraisals and a future closing date, it is difficult to estimate a pro forma allocation of purchase price. However, for purposes of these pro forma statements we have assumed that the consideration in excess of the net assets acquired is related to a step-up in the value of Texas Genco’s fixed assets, a step-up in the value of Texas Genco’s emission credit inventory and Goodwill. Once the Acquisition is closed, the excess of the estimated purchase price may differ considerably from these assumptions based on the results of appraisals, finalization of the purchase price as a result of closing and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

On a pro forma basis we have made a number of assumptions per our best estimates. We have assumed an average remaining useful life of 25 years of the fixed assets acquired, rendering a significant incremental pro forma increase in depreciation expense. The amortization of the emission credit inventory is based on Texas Genco’s use of credits for the period. The amortization of the assumed liability for Texas Genco’s out-of-market contracts is mimicking the expected amortization for the nine month period which would begin on January 1, 2006. Actual results may differ considerably from these pro forma assumptions.

Total	$	(150,727	)

Supplementary information:

Sensitivity analysis for adjustable rate financing — as part of the refinancing, the new term loan will be subject to an adjustable rate of interest. For the nine months ended September 30, 2005, on a pro forma basis, if the interest rate would increase or decrease by 1/8% for the entire period, income from continuing operations would increase or decrease by $1.4 million, respectively.

(1)	The Pro Forma Combined Texas Genco LLC Statement of Operations for the Year Ended December 31, 2004 can be found in Exhibit 99.11.
(2)	On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with AmerenUE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation.
(3)	Amounts reflect the pro forma results of the additional 13.2% interest in STP acquired in the ROFR as if the acquisition had occurred on January 1, 2004.
(4)	Reflects the reversal of interest expense associated with NRG’s existing debt structure, prior to the acquisition of Texas Genco and the recording of interest expenses associated with the new debt structure:

Reversal of interest expense associated with NRG’s existing debt structure	$	181,908
Interest expense associated with the refinancing of NRG’s debt		(117,545	)
Total	$	64,363

(5)	Reflects the tax effect of both the pro forma adjustments (pro forma effective tax rate of 39.5%) and Texas Genco’s pass-through earnings (pro forma effective tax rate of 35.2%) which will now generate taxable income for the combined entity.
(6)	Reflects the reversal of Management Fees of $10 million which will not be applicable following the Acquisition and the additional amortization expense for emission credits of $122 million based on the amount of credits used during this period by Texas Genco
(7)	Reflects the increase in depreciation expense due to the step-up in the value of fixed assets at the Acquisition of Texas Genco3.

³ Due to the lack of asset appraisals and a future closing date, it is difficult to estimate a pro forma allocation of purchase price. However, for purposes of these pro forma statements we have assumed that the consideration in excess of the net assets acquired is related to a step-up in the value of Texas Genco’s fixed assets, a step-up in the value of Texas Genco’s emission credit inventory and Goodwill. Once the Acquisition is closed, the excess of the estimated purchase price may differ considerably from these assumptions based on the results of appraisals, finalization of the purchase price as a result of closing and other analyses, which the Company is obtaining. The other analyses include actuarial studies of employee benefit plans, income tax effects of the Acquisition, analyses of operations to identify assets for disposition and the evaluation of staffing requirements necessary to meet future business needs. Ultimately, the excess of the purchase price over the fair value of the net tangible and identified intangible assets acquired will be recorded as goodwill.

On a pro forma basis we have made a number of assumptions per our best estimates. We have assumed an average remaining useful life of 25 years of the fixed assets acquired, rendering a significant incremental pro forma increase in depreciation expense. The amortization of the emission credit inventory is based on Texas Genco’s use of credits for the year. We have not included amortization of the out-of-market contracts for the year ended December 31, 2004 as the majority of these contracts were entered in December 2004 or during 2005. Actual results may differ considerably from these pro forma assumptions.

Supplementary information:

Sensitivity analysis for adjustable rate financing – as part of the refinancing, the new term loan will be subject to adjustable rate of interest. For the year ended December 31, 2004, on a pro forma basis, if the interest rate would increase or decrease by 1/8% for the entire year, income from continuing operations would increase or decrease by $1.8 million, respectively.

Footnotes to Pro Forma Combined Earnings per Share for the Nine Months Ended September 30, 2005

(1)	The Pro Forma Combined Texas Genco LLC Statement of Operations for the Nine Months Ended September 30, 2005 can be found in Exhibit 99.10.
(2)	On December 8, 2005 NRG Energy, Inc. signed an Asset and Purchase Sale Agreement with AmerenUE to sell all of the assets of Audrain. For purposes of these pro forma statements we have reflected the sale of assets of Audrain as a discontinued operation.
(3)	Reflects pro forma results of an additional 13.2% interest in STP acquired in the ROFR for the period from January 1, 2005 until ROFR acquisition date on May 19, 2005.
(4)	On a pro forma basis it is assumed that 5.5% Mandatorily Convertible Preferred Shares have been issued and outstanding as of January 1, 2004. As such, for the nine months ended September 30, 2005, there is an increase in dividends for preferred dividend of 20,625.

The 4% Convertible Perpetual Preferred Shares have been issued and outstanding for the entire nine month period ended September 30, 2005 and are already reflected in the historical NRG Earnings per Share calculation.

(5) This increase in the number of weighted average shares is for shares issued to the public, and for the shares issued to the Sellers:

Shares issued to the Sellers – new issuance	35,406
Shares issued to the public	23,474
Total increase in number of weighted average shares	58,880

It should be noted that for pro forma purposes we have assumed that all the shares issued to the Sellers are newly issued. Per the Acquisition Agreement 19,346,788 shares will be issued from treasury, however, on a pro forma basis that is not possible from January 1, 2004 as there were no shares in treasury. For this reason, the weighted average number of common shares outstanding for the nine months ended September 30, 2005 are also higher than what is expected after the closing of the Acquisition.

(6) This increase in the add back for preferred stock dividends is due to the following dilutive preferred stocks:

Dividend for 4% Convertible Perpetual Preferred Shares	12,600
Dividend for 5.5% Mandatorily Convertible Preferred Shares	20,625
Total Preferred Dividend	33,225

(7) On a pro-forma basis, these items are dilutive.
