    --  Received stockholder approval from both companies
    --  Entered into revolving credit facility and agreements to borrow

        merger agreement
    --  Received FERC approval and NY Public Service Commission clearance
    --  Expect to close by the end of the year
--  Third quarter financial results improved year-over-year and reflect
    continued depressed commodity prices and weak economic conditions

    million charged in third quarter

RRI Energy, Inc. today is reporting open EBITDA of $212 million for the third quarter of 2010, compared to $133 million for the third quarter of 2009. The improvement was primarily due to improved energy margins driven by higher heat rates related to warmer weather in July and early August and improved economic conditions compared to the same period last year. The company reported adjusted EBITDA of $212 million in the third quarter of 2010, compared to $100 million in the third quarter of 2009. The improvement was primarily due to the items mentioned above and a reduction in losses from coal hedges. Free cash flow provided by continuing operations during the first nine months of 2010 was $84 million, compared to a use of cash of ($182) million for the first nine months of 2009. The improvement was primarily a result of improved earnings and lower environmental capital expenditures.

"We have made excellent progress toward completing the steps necessary to finalize our proposed merger with Mirant and expect to close the transaction by the end of the year after we receive clearance from the Department of Justice," said Mark Jacobs, president and chief executive officer of RRI Energy. "Third quarter financial results and market conditions have improved relative to last year, but still reflect continued depressed commodity prices and weak economic conditions."

Open EBITDA was $241 million for the first nine months of 2010, compared to $129 million for the same period of 2009. Adjusted EBITDA was $244 million for the first nine months of 2010, compared to $42 million for the same period of 2009. The improvements were due to the same factors as described above, partially offset by increased plant operation and maintenance expenses to improve equipment performance.

Income from continuing operations before income taxes for the third quarter of 2010 was $41 million, compared to a loss from continuing operations of $9 million for the third quarter of 2009. The 2010 reported results include net unrealized gains from energy derivatives of $51 million, $5 million in merger-related costs and a $113 million charge for long-lived assets impairments. The reported numbers for 2009 include net unrealized gains from energy derivatives of $7 million.

The loss from continuing operations before income taxes for the first nine months of 2010 was $361 million, compared to $334 million for the first nine months of 2009. The 2010 reported results include net unrealized gains from energy derivatives of $112 million, a $17 million charge for western states litigation and similar settlements, $19 million in merger-related costs and a $361 million charge for long-lived assets impairments. The reported numbers for 2009 include net unrealized losses from energy derivatives of $30 million and $8 million in severance charges. Operating cash flow from continuing operations was $252 million for the first nine months of 2010, compared to a use of cash of ($275) million for the same period of 2009.

(1) Open energy gross margin is calculated using the day-ahead and
    real-time market power sales prices received by the plants less
    market-based delivered fuel costs.
(2) Other margin represents power purchase agreements, capacity payments,
    ancillary services revenues and selective commercial strategies
    relating to optimizing our assets.
(3) Segment profitability measure.
(4) This figure excludes the effects of hedges and other items and
    unrealized gains/losses on energy derivatives.
(5) Total margin capture factor is calculated by dividing open gross
    margin generated by the plants by the total available open gross
    margin, assuming 100% availability.
(6) Excludes generation related to power purchase agreements.
(7) Represents open energy gross margin divided by generation.
