•

The combination would create a leading regional energy provider with utility operations serving over 6 million customers in seven states, approximately $16 billion in annual revenues and $1.4 billion in annual net income, based on combined figures as of December 31, 2009, and approximately 24,000 megawatts of generating capacity from a diverse mix of regional coal, nuclear, natural gas, oil and renewable power resources.

•

The transaction is anticipated to be accretive to FirstEnergy earnings in the first year following the close.

•

Allegheny Energy shareholders would receive 0.667 shares of FirstEnergy common stock in exchange for each share of Allegheny Energy they own. Following the completion of the merger, it is anticipated that FirstEnergy shareholders will own approximately 73 percent and Allegheny Energy shareholders will own approximately 27 percent of the combined company.

     The merger is expected to close in the first half of 2011, subject to customary closing conditions, including shareholder and regulatory approvals, as outlined in the joint proxy statement/prospectus that is being mailed to shareholders.
