Factors that could cause actual results to differ materially from those contemplated above include, among others, general economic conditions, hazards customary in the power industry, competition in wholesale power markets, the volatility of energy and fuel prices, failure of customers to perform under contracts, changes in the wholesale power markets and related government regulation, the condition of capital markets generally, our ability to access capital markets, our substantial indebtedness and the possibility that we may incur additional indebtedness, adverse results in current and future litigation, delays in hiring new independent auditors, delays in or failure to meet closing conditions in announced transactions, failure to identify or successfully implement acquisitions and repowerings, adverse rulings on our RMR agreements and cost tracker for scheduled expenses, resulting in us refunding certain payments received to date, and FERC not approving the basic LICAP market design.

Market Environment in which We Operate Deregulation / Reregulation On the deregulation / reregulation

Market Environment in which We Operate Deregulation / Reregulation On the deregulation / reregulation spectrum, we are entering a period of stasis. The five ISOs will move forward methodically to refine their market model. Other regions are static. Industry Structure Further utility disaggregation is unlikely. Industry consolidation, while desirable, necessary and inevitable, will be delayed by the merchant generation industry’s current debt mountain. Market Fundamentals Supply-demand imbalance has peaked, but how long we remain in the commodity price cycle trough is an open issue. The timing of the correction depends much more on the actions of industry participants (supply) than on the strength of economic recovery (demand). Role of Fuel While one can argue about the sustainability of currently high gas prices, higher gas volatility (on a delivered basis) is a near certainty. And now Eastern coal has shown more volatility. 28

Keys to Success in Merchant Generation Industry: Four fundamentals Four imperatives § Capital intensive

Keys to Success in Merchant Generation Industry: Four fundamentals Four imperatives § Capital intensive - yes; 1 MUST own a generation § Highly cyclical, inelastic 2 MUST be geographically Labor intensive - no demand, supply driven § Pure commodity, but inability to store cause very high volatility portfolio at a competitive cost relative to replacement cost diversified, in multiple markets 3 MUST have scale in key markets 4 MUST develop and expand § Assets relatively illiquid our route to market and generally movable 29

We must own. . . plus it helps if we have. . . § Generation which is price competitive § The scale to negotiate as § Generation that competitively serves § Limited or no competitors on both a SRMC and LRMC basis; load-shaping requirements through base, intermediate and peaking capacity; equals with comparable capabilities § Generation, from various fuels, such that we can offer the retail load providers at least a partial hedge against gas price spikes 31

Adjusted EBITDA Reconciliation (cont. ) EBITDA, Adjusted EBITDA and adjusted net income are non-GAAP

Adjusted EBITDA Reconciliation (cont. ) EBITDA, Adjusted EBITDA and adjusted net income are non-GAAP financial measures. These measurements are not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance. The presentation of Adjusted EBITDA and adjusted net income should not be construed as an inference that NRG’s future results will be unaffected by unusual or non-recurring items. EBITDA represents net income before interest, taxes, depreciation and amortization. EBITDA is presented because NRG considers it an important supplemental measure of its performance and believe debt-holders frequently use EBITDA to analyze operating performance and debt service capacity. EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our operating results as reported under GAAP. Some of these limitations are: • EBITDA does not reflect cash expenditures, or future requirements for capital expenditures, or contractual commitments; • EBITDA does not reflect changes in, or cash requirements for, working capital needs; • EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on debts; • Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA does not reflect any cash requirements for such replacements; and • Other companies in this industry may calculate EBITDA differently than NRG does, limiting its usefulness as a comparative measure. Because of these limitations, EBITDA should not be considered as a measure of discretionary cash available to use to invest in the growth of NRG’s business. NRG compensates for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only supplementally. See the statements of cash flow included in the financial statements that are a part of this press release. Adjusted EBITDA is presented as a further supplemental measure of operating performance. Adjusted EBITDA represents EBITDA adjusted for reorganization, restructuring, impairment and corporate relocation charges, discontinued operations, and write downs and losses on the sales of equity method investments; factors which we do not consider indicative of future operating performance. The reader is encouraged to evaluate each adjustment and the reasons NRG considers it appropriate for supplemental analysis. As an analytical tool, Adjusted EBITDA is subject to all of the limitations applicable to EBITDA. In addition, in evaluating Adjusted EBITDA, the reader should be aware that in the future NRG may incur expenses similar to the adjustments in this presentation. 41
