Exelon Raises 2005 Earnings Guidance, Provides Guidance for 2006

CHICAGO (Aug. 5, 2005) Exelon today raised its guidance for 2005 GAAP earnings per share to a range of $3.05 to $3.20 and its guidance for 2005 adjusted (non-GAAP) operating earnings per share to a range of $3.00 to $3.15. The company also provided guidance for 2006 adjusted (non-GAAP) operating earnings per share of between $3.00 and $3.30 (on a stand-alone basis) during a conference with analysts and investors today. The company’s earnings guidance is based on the assumption of normal weather in the second half of 2005 and the full year of 2006. These estimates do not include any impact of future changes to GAAP.

Positive drivers of earnings growth in 2005 and 2006 include higher generation margins and load growth at ComEd and PECO.

“Since its inception, Exelon has provided one of the best total returns in our industry. The last twelve months have been no exception,” said John W. Rowe, Exelon’s chairman, president and CEO.

“Our success is attributable to many things, including dramatic improvements in our nuclear and other operations, and rigorous financial discipline,” said Rowe. “But in a very real sense, our success is competition’s success. Over the past five years, we have worked tirelessly to promote wholesale competition and to implement the mandate of our state policymakers. The evidence is increasingly clear that our shareholders, our customers and our employees are all benefiting as a consequence. And we believe that our impending merger with PSEG will continue that process.”

Adjusted (non-GAAP) operating earnings, which generally exclude significant one-time charges or credits that are not normally associated with ongoing operations and unrealized mark-to-market adjustments from non-trading activities, are provided as a supplement to results reported in accordance with GAAP. Management uses such adjusted (non-GAAP) operating earnings measures internally to evaluate the company’s performance and manage its operations. Exelon’s outlook for 2005 adjusted (non-GAAP) operating earnings excludes unrealized mark-to-market adjustments from non-trading activities, income resulting from investments in synthetic fuel-producing facilities,
