PRINCETON, NJ; June 4, 2014 — NRG Yield, Inc. (NYSE: NYLD) has entered into an agreement with Terra-Gen Power LLC to acquire the Alta Wind facility located in Tehachapi, Calif., for $870 million, plus the assumption of $1.6 billion of non-recourse project financings and subject to customary working capital adjustments.

“Alta Wind is a landmark investment for NRG Yield,” said David Crane, NRG Yield’s Chairman and Chief Executive Officer. “The acquisition of the largest wind facility on the North American continent highlights not only our commitment to carbon-free generation, but also the strength of our acquisition capabilities to compete for contracted assets of world-class quality in the competitive marketplace. Alta Wind contributes to our objective of sustainable and visible dividend growth for our investors while supporting the generation of carbon-free electricity for thousands of homes through large-scale wind.”

Appendix A-1: Adjusted EBITDA and Cash Available for Distribution Reconciliation

The following table summarizes the calculation of adjusted EBITDA and cash available for distribution to net income:

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 Yield’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 Yield 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 Yield 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 Yield’s business. NRG Yield compensates for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only as supplements. 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 Yield 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 Yield may incur expenses similar to the adjustments in this news release.

Cash available for distribution is Adjusted EBITDA plus cash dividends from unconsolidated affiliates, less maintenance capital expenditures, pro-rata adjusted EBITDA from unconsolidated affiliates, cash interest paid, income taxes paid, principal amortization of indebtedness and changes in others assets. Management believes cash available for distribution is a relevant supplemental measure of the Company’s ability to earn and distribute cash returns to investors.
