Exelon Corporation Reaffirms 2003 Guidance; Targets to Reduce Workforce 10 percent By 2006

CHICAGO (August 6, 2003) — Senior executives with Exelon Corporation met with investors and analysts today in New York City to update the financial community on progress of The Exelon Way, the company’s program aimed to improve cash flow by $300 — $600 million in cash savings annually by focusing on operational excellence, simplifying procedures and standardizing processes.

Exelon reaffirmed its guidance for 2003 of earnings per share at the upper end of a range of $4.80 to $5.00 and provided guidance of between $5.15 and $5.45 per share for 2004.

As part of The Exelon Way, approximately 1,200 positions are targeted for elimination by 2004, and another 700 by 2006. Positions identified for elimination in 2003 will be complete by November. The majority of the reductions will come from professional and management employees. Overall, Exelon targets to reduce its workforce by about 1900 positions — or 10 percent — by 2006.

“Exelon is committed to treating its employees fairly and will facilitate voluntary separation agreements wherever possible, “ says Chairman and CEO John Rowe. “To that end, we are providing an updated and improved severance package for all affected employees.”

Eliminating redundancies in job functions is only one aspect of The Exelon Way. The program also focuses on streamlining operations, realigning our supply chain and information technology structure, and realizing opportunities for process improvements throughout the organization.
