ATLANTA — Mirant Corporation (NYSE: MIR) today reported a net loss of $26 million for the quarter ended September 30, 2006, compared to a net loss of $1,515 million for the same period in 2005. For the first nine months of 2006, Mirant reported net income of $540 million, compared to a net loss of $1,514 million for the first nine months of 2005. The loss per share for the quarter ended September 30, 2006 was $0.09 per diluted share and earnings per share for the first nine months of 2006 were $1.77 per diluted share.

Excluding unrealized mark-to-market gains of $244 million, impairment losses of $396 million related to the six U.S. natural gas plants to be sold, impairment losses of $120 million related to the construction and development costs for the suspended Bowline combined cycle unit, and other non-recurring charges, Mirant reported adjusted net income for the third quarter of 2006 of $253 million, resulting in adjusted earnings per diluted share of $0.85. Excluding unrealized mark-to-market gains of $650 million,

the impairments totaling $516 million, a $72 million write off of a Philippines deferred tax asset and other non-recurring charges, Mirant reported adjusted net income for the first nine months of 2006 of $462 million, resulting in adjusted earnings per diluted share of $1.51.

Adjusted EBITDA from continuing operations was $214 million for the quarter, compared to $191 million for the same period in 2005. For the first nine months of 2006, adjusted EBITDA from continuing operations was $474 million, compared to $202 million for the same period in 2005. The period over period increases for the quarter and the first nine months of the year resulted primarily from an increase in the realized value of hedges for the 2006 periods compared to the 2005 periods, offset in part by lower power prices and lower generation volumes in 2006.

“The performance of our continuing business was strong again this quarter. Our hedging in earlier periods continued to mitigate the impact of lower market prices this year. Our strategy remains to provide predictable financial results by hedging our portfolio as market conditions warrant,” said Edward R. Muller, chairman and chief executive officer.

Net cash provided by operating activities during the third quarter was $388 million. Net cash provided by operating activities was $1.039 billion for the first nine months of 2006, excluding bankruptcy payments of $765 million.

As of September 30, 2006, the company, including discontinued operations, had cash and cash equivalents of $1.22 billion, total available liquidity of $1.70 billion and total outstanding debt of $4.66 billion.

Adjusted EBITDA from discontinued operations was $200 million for the quarter, compared to $187 million for the same period in 2005. For the first nine months of 2006, adjusted EBITDA from discontinued operations was $533 million, compared to $469 million for the same period in 2005.

Asset Sale Process

The company’s previously announced auctions of its Philippine and Caribbean businesses and six U.S. natural gas plants continue to proceed with targeted completion by mid-2007.

As previously disclosed, the generator at unit 2 of Sual failed in July. Recently, the generator at unit 1 similarly failed. The company expects unit 2 back in service in March and unit 1 back in service later in 2007. Mirant expects to have a binding agreement for the sale of its Philippine business near the end of 2006 or early next year and to close the transaction by mid-2007.

Share Repurchase Program

In August 2006, the company completed its “Dutch auction” self tender offer, in which the company repurchased 43,000,000 shares of common stock for an aggregate of approximately $1.23 billion. On September 28, 2006, the company announced an additional $100 million share repurchase program. As of October 31, 2006, the company had purchased 1,180,300 common shares under the $100 million share repurchase program.

Guidance

Mirant is updating its guidance as follows:

· Adjusted EBITDA guidance for 2006 is $619 million for continuing operations and $643 million for discontinued operations

· Adjusted EBITDA guidance for 2007 is $962 million for continuing operations and $299 million for discontinued operations (discontinued operations reflects the first six months only)

The actual financial results for discontinued operations in 2007 will depend on the closing dates of the sales of those operations.
