(Exact Name of Registrant as Specified in Its Charter) Ohio 34-1843785 (State or Other Jurisdiction of (I.R.S. Employer Identification No.) corporation or Organization) 76 South Main Street Akron, Ohio 44308 (Address of Principal Executive Offices, Including Zip Code) -------------------------------------- GPU Companies Employee Savings Plan for Nonbargaining Employees GPU Companies Employee Savings Plan for Employees Represented by IBEW System Council U-3 GPU Companies Employee Savings Plan for Employees Represented by IBEW Local 459 and UWUA Local 180 GPU Companies Employee Savings Plan for Employees Represented by IBEW Local 777 (Full Title of the Plan) -------------------------------------- David W. Whitehead Copy to: Corporate Secretary Edward W. Moore, Esq. FirstEnergy Corp. Calfee, Halter & Griswold LLP 76 South Main Street 1400 McDonald Investment Center Akron, Ohio 44308 800 Superior Avenue (330) 384-4400 Cleveland, Ohio 44114 (216) 622-8200 (Name, Address and Telephone Number, Including Area Code, of Agent for Service) -------------------------------------- Explanatory Statement In Connection With the Filing of a Related Registration Statement on Form S-8 Filed Pursuant to Instruction E of Form S-8 Contemporaneously with the filing of this Post-Effective Amendment No. 1 to its Registration Statement on Form S-8 (File No. 333-72764) (this "Registration Statement"), FirstEnergy Corp., an Ohio corporation (the "Company"), is filing with the Securities and Exchange Commission (the "Commission") a new Registration Statement on Form S-8. The new Registration Statement (the "New Registration Statement") relates to the registration, among other offers and sales of shares of the Company's common stock, par value $0.10 per share, of the offer and sale of 133,867 shares of common stock (the "Carryover Shares") pursuant to the FirstEnergy Corp. Savings Plan (the "Savings Plan"). The Savings Plan is sponsored by the Company. The Company had originally registered the Carryover Shares pursuant to this Registration Statement in anticipation of offering interests in the Company's common stock to participants in the GPU Companies Employee Savings Plan for Nonbargaining Employees, the GPU Companies Employee Savings Plan for Employees Represented by IBEW System Council U-3, the GPU Companies Employee Savings Plan for Employees Represented by IBEW Local 459 and UWUA Local 180 and the GPU Companies Employee Savings Plan for Employees Represented by IBEW Local 777 (collectively, the "GPU Plans"). Under the terms of the Agreement and Plan of Merger, dated as of August 8, 2000, between the Company and GPU, Inc., a Pennsylvania corporation ("GPU"), GPU was merged into the Company (the "Merger"). As a result of the Merger, interests in the Company's common stock were offered to participants under the terms of the GPU Plans upon and after the Merger. Following the filing of this Amendment No. 1, the Carryover Shares are no longer available for new offers or sales under the GPU Plans. On January 7, 2003, the GPU Plans were merged into the Savings Plan and, as a result, the Savings Plan is the successor to the GPU Plans. The Company desires to have the Carryover Shares be included among the shares of common stock for which offers and sales under the Savings Plan are registered under the New Registration Statement. Consequently, in accordance with the principles set forth in Interpretation 89 under Section G, "Securities Act Forms" of the Manual of Publicly Available Telephone Interpretations of the Division of Corporation Finance of the Commission (July 1997 as supplemented) and Instruction E to Form S-8, (1) the Company is registering the offer and sale of the Carryover Shares pursuant to the Savings Plan by means of the New Registration Statement, (2) the registration fee of $1,130 allocable to the Carryover Shares, which the Company paid to the Commission in connection with the original filing of this Registration Statement, is carried over to the New Registration Statement, and (3) this Registration Statement is being amended on a post-effective basis to describe the change from the GPU Plans to the Savings Plan, and accordingly, no shares remain registered hereunder which have not been sold. 2 SIGNATURES The Registrant.
