Certain statements included in this current report on Form 8-K are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements above include, but are not limited to, the successful consummation of the sale, which is dependent in part on the meeting of certain closing conditions, and the timing of the closing of such sale and approval of the bankruptcy court. Although NRG believes that its expectations are reasonable, it can give no assurance that these expectations will prove to have been correct.

The foregoing review of factors that could cause NRG’s actual results to differ materially from those contemplated in the forward-looking statements included in this current report on Form 8-K should not be construed as exhaustive.
