Generation/Business (formerly NRG Business): First Quarter Adjusted EBITDA was $429 million; $106 million lower than first quarter 2015 primarily driven by:

• East Region: $179 million lower due to declining energy margins from milder weather, declines in gas prices and dark spreads, and lower capacity revenues due to deactivations, partially offset by increased contract margins attributable to new load contracts and lower supply costs;
• West Region: $63 million increase due primarily to sale of $47 million in emission credits and lower operating costs on timing of outages; and
• Gulf Coast Region: $7 million increase due primarily to higher South Central capacity revenues and lower supply costs to serve load contracts, and favorable operating costs driven by reduced outages across the region, partially offset by lower energy margins in Texas from the decline in power prices and milder weather.

Retail Mass (formerly NRG Home Retail): First quarter Adjusted EBITDA was $151 million, $15 million lower than first quarter 2015 from milder weather, partially offset by lower supply costs and operating cost efficiencies.

Renewables (formerly NRG Renew): First quarter Adjusted EBITDA was $42 million, $20 million higher than first quarter 2015 due primarily to increased production at Ivanpah, higher generation from wind assets and new solar projects achieving commercial operations in late 2015.

NRG Yield: First quarter Adjusted EBITDA was $188 million, $56 million higher than first quarter 2015 due to increased wind production and the acquisition of Desert Sunlight.

NRG Strategic Developments

Residential Solar

NRG today announces the conclusion of the strategic review process for residential solar, integrating it into NRG and streamlining both its model and market. The operation will transition to an originate-and-monetize to third party model. As part of this change, NRG has entered into agreements with both Sunrun Inc. (Nasdaq: RUN) and Spruce Finance Inc., whereby both parties will be able to purchase NRG originated residential solar contracts and provide support over the life of the customer contract. Additionally, as NRG streamlines its go-to-market approach, residential solar will focus on three markets where it already has a well-established foothold – New Jersey, New York and Massachusetts – while maintaining a longer-term option to participate in NRG Retail’s core Texas market as economics for residential solar improve. NRG will incur one-time costs to achieve of approximately $20 million in 2016.

EVgo

NRG has agreed to sell a majority stake in its EVgo business to Vision Ridge Partners for total consideration of approximately $50 million, consisting of $19.5 million (subject to working capital adjustments) payable to NRG and the remainder contributed as capital to the business. NRG also has future earnout potential of up to $70 million based on future adjusted EBITDA targets. NRG will retain its obligations under the 2012 California Public Utilities Commission settlement. The sale of a majority interest will result in NRG reporting EVgo on an equity earnings basis.

Next Drop Down to NRG Yield

During the second quarter of 2016, NRG intends to offer the remaining 51.05% of the California Valley Solar Ranch (CVSR) facility, a 250 MW solar facility located in San Luis Obispo, CA, to NRG Yield. NRG Yield currently owns 48.95% of the CVSR facility.

2016 Guidance

NRG is reaffirming its guidance range for fiscal year 2016 with respect to both Adjusted EBITDA and FCF before growth investments, including the results of the residential solar business and EVgo.

Capital Allocation Update

On April 7, 2016, Midwest Generation, LLC (MWG) entered into an agreement to sell certain quantities of unforced capacity revenues through the 2018/19 delivery year to a trading counterparty for net proceeds of $253 million. MWG will continue to operate the generation facilities and remains responsible for performance penalties and eligible for performance bonus payments, if any. NRG intends to allocate proceeds from this transaction toward additional NRG level delevering or redemption of the Company’s Convertible Preferred stock.

Year to date, through May 5, 2016 the Company utilized $214 million ($229 million par) of the $1.3 billion of 2016 NRG level capital allocated to debt repurchases.

On April 18, 2016, NRG declared a quarterly dividend on the Company's common stock of $0.03 per share, payable May 16, 2016 to stockholders of record as of May 2, 2016 representing $0.12 on an annualized basis.

The Company’s common stock dividend, debt reduction and share repurchases are subject to available capital, market conditions and compliance with associated laws and regulations.

EBITDA and Adjusted EBITDA 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 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 (including loss on debt extinguishment), taxes, depreciation and amortization. EBITDA is presented because NRG considers it an important supplemental measure of its performance and believes 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 debt or cash income tax payments;
• 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 news release.

Adjusted EBITDA is presented as a further supplemental measure of operating performance. Adjusted EBITDA represents EBITDA adjusted for mark-to-market gains or losses, asset write offs and impairments; and 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 news release.

Adjusted cash flow from operating activities is a non-GAAP measure NRG provides to show cash from operations with the reclassification of net payments of derivative contracts acquired in business combinations from financing to operating cash flow, as well as the add back of merger and integration related costs. The Company provides the reader with this alternative view of operating cash flow because the cash settlement of these derivative contracts materially impact operating revenues and cost of sales, while GAAP requires NRG to treat them as if there was a financing activity associated with the contracts as of the acquisition dates. The Company adds back merger and integration related costs as they are one time and unique in nature and do not reflect ongoing cash from operations and they are fully disclosed to investors.

Free cash flow (before Growth investments) is adjusted cash flow from operations less maintenance and environmental capital expenditures, net of funding, and preferred stock dividends and is used by NRG predominantly as a forecasting tool to estimate cash available for debt reduction and other capital allocation alternatives. The reader is encouraged to evaluate each of these adjustments and the reasons NRG considers them appropriate for supplemental analysis. Because we have mandatory debt service requirements (and other non-discretionary expenditures) investors should not rely on free cash flow before Growth investments as a measure of cash available for discretionary expenditures.
