Item 2.02. Results of Operations and Financial Condition.

On November 9, 2012, we issued an earnings release announcing our financial results for the three and nine months ended September 30, 2012.  The earnings release is furnished as Exhibit 99.1 to this Form 8-K and incorporated by reference herein. This Form 8-K and the earnings release are available at www.genon.com in the investor relations section.

In our earnings release, we use certain non-GAAP financial measures.  We think that these non-GAAP financial measures provide meaningful representations of our consolidated operating and financial performance and are useful to us and investors, analysts, rating agencies, banks and other parties in facilitating the analysis of our results of operations from one period to another and comparing our performance to our peers and providing a more complete understanding of factors and trends affecting our business.  However, our non-GAAP financial measures may not be comparable to similarly titled non-GAAP financial measures used by other companies.  The non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for GAAP financial measures.  Investors should review our consolidated financial statements and publicly filed reports in their entirety and not rely on any single financial measure.

These non-GAAP financial measures include adjusted net income/loss and adjusted EBITDA.  We discuss these non-GAAP financial measures in Exhibit 99.2, including the reasons that we think that these measures provide useful information and the additional purposes for which these measures are used.  Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measure can be found in our earnings release.

Item 9.01.  Financial Statements and Exhibits.

(d)                                 Exhibits. We furnish the following exhibits:

99.1—Press Release dated November 9, 2012

99.2—Explanation of Non-GAAP Financial Measures

INFORMATION FURNISHED

The information in Item 2.02 and in the exhibits included as part of this Form 8-K are being furnished, not filed. Accordingly, the information will not be incorporated by reference into any filing or report by us with the Securities and Exchange Commission, whether made before or after the date hereof, unless specifically identified as being incorporated by reference therein.
