The transaction is expected to close in the fourth quarter, subject to receipt of third party consents and other closing conditions.

Appendix Table A-1: Adjusted EBITDA and CAFD Reconciliation

The following table summarizes the calculation of Adjusted EBITDA and CAFD and provides a reconciliation to income before taxes:

($ in millions)	75% interest of EME Wind Drop DownRun-Rate(4)
Income/(Loss) before Tax	(1	)
Plus:
Interest Expense, net	10
Depreciation, Amortization, and ARO Expense	45
Adjustments to reflect Yield’s pro-rata share of Adjusted EBITDA from Unconsolidated Affiliates	1
Adjusted EBITDA	55
Pro-rata Adjusted EBITDA from unconsolidated affiliates	(10	)
Cash distributions from unconsolidated affiliates	10
Tax Equity Proceeds	2
Distributions to non-controlling interest	(7	)
Cash interest paid	(11	)
Maintenance Capital expenditures	(1	)
Principal amortization of indebtedness	(17	)
Cash Available for Distribution	21

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

(4)  75% interest in 814 net MW of wind assets primarily acquired by NRG in the EME transaction reflecting the useful life of assets, Adjusted EBITDA will be consolidated on NRG Yield, 75% pro-rata Adjusted EBITDA is approximately $41MM

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 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 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.
