Thursday, February 26, 2004

Pepco Holdings, Inc. (NYSE: POM ) today announced a consolidated loss for the quarter ended Dec. 31, 2003 of $62 million, or 36 cents per share, on operating revenue of $1.5 billion. The 2003 results include the unfavorable impact of a $67 million, or 39 cents per share, non-cash write down of PHI 's investment in Starpower Communications, LLC to fair market value.

"The results for the fourth quarter are not typical and have been negatively impacted by the Starpower non-cash write down, weather, the effects of the Mirant bankruptcy, and adverse wholesale markets" reported Dennis Wraase, PHI President and Chief Executive Officer. "Looking forward, we believe the results achieved for the quarter in 2002 are more representative of what we would expect in the future." For the fourth quarter of 2002, PHI reported consolidated earnings of $26 million, or 16 cents per share on operating revenue of $1.6 billion. These earnings included the unfavorable impact of $14 million, or 8 cents per share, resulting primarily from severance costs during that quarter.

PHI's consolidated earnings for the year ended Dec. 31, 2003 , were $114 million, or 66 cents per share, on operating revenue of $7.3 billion compared with consolidated earnings of $211 million, or $1.61 per share, on operating revenue of $4.3 billion in 2002. Details of the more significant financial events during both the 12-month period and quarter ended Dec. 31, 2003 are included in the financial schedules that follow.

The 2003 quarterly and year-end financial results include PHI's and its subsidiaries'' operating results for the full periods. Pursuant to purchase accounting rules, the 2002 periods include the results of Potomac Electric Power Company ("Pepco") and its pre-merger subsidiaries for the entire periods consolidated with Conectiv '' and its subsidiaries'' results starting on Aug. 1, 2002, the date the merger of Pepco and Conectiv was completed. Accordingly, comparisons to the 2002 results for the year-end periods are not meaningful.

STATUS OF MIRANT MATTER
On July 14, 2003 , Mirant Corporation and most of its subsidiaries filed a voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As more fully described in PHI's Form 10-Q for the quarter ended Sept. 30, 2003 , Pepco has several significant commercial relationships with Mirant and its subsidiaries that could be adversely affected by the bankruptcy filing. These consist primarily of agreements by Mirant to purchase from Pepco the capacity and energy that Pepco is obligated to purchase from third parties under several power purchase agreements ( PPA -Related Obligations). The prices at which Mirant is required to purchase capacity and energy from Pepco under the PPA-Related Obligations are substantially in excess of current market prices. Mirant has filed a motion to reject the PPA-Related Obligations in the bankruptcy and related proceedings. On Dec. 23, 2003 , the U.S. District Court for the Northern District of Texas ("District Court") issued a Memorandum and Order denying Mirant''s motion to reject the PPA -Related Obligations. Mirant has appealed the District Court's Order to the U.S. Court of Appeals for the Fifth Circuit. Oral argument on the appeal is scheduled for May 2004.
