Exhibit No.        Description
-----------        -----------
   99.1            Press Release issued by FirstEnergy Corp., dated
                   October 23, 2003
   99.2            Consolidated Report to the Financial Community, dated
                   October 23, 2003

Item 12.  Results of Operations and Financial Condition

         On October 23, 2003, FirstEnergy Corp. issued two public announcements,
which are attached as Exhibits 99.1, and 99.2 hereto and incorporated by
reference. FirstEnergy's Press Release and Consolidated Report to the Financial
Community contain non-GAAP financial measures. Generally, a non-GAAP financial
measure is a numerical measure of a company's historical or future financial
performance, financial position, or cash flows that either excludes or includes
amounts that are not normally excluded or included in the most directly
comparable measure calculated and presented in accordance with accounting
principles generally accepted in the United States, or GAAP. Pursuant to the
requirements of Regulation G, FirstEnergy has provided quantitative
reconciliations within the Press Release and Consolidated Report to the
Financial Community of the non-GAAP financial measures to the most directly
comparable GAAP financial measures.

         The Press Release and Consolidated Report to the Financial Community
include normalized earnings per share, which is not calculated in accordance
with GAAP because it excludes the impact of "unusual items". Unusual items
reflect the impact on earnings of events that are not routine, are related to
prior periods, are related to discontinued businesses or are the cumulative
effect of an accounting change. Management believes presenting normalized
earnings calculated in this manner provides useful information to investors in
evaluating the ongoing results of FirstEnergy's businesses and assists investors
in comparing the company's operating performance to the operating performance of
others in the energy sector. FirstEnergy's management frequently references
these non-GAAP financial measures in its decision-making, using them to
facilitate historical and ongoing performance comparisons as well as comparisons
to the performance of peer companies.

         The non-GAAP information presented in the Press Release and
Consolidated Report to the Financial Community should be considered in addition
to, and not as a substitute for, reported earnings per share prepared in
accordance with GAAP.


         Forward-Looking Statement: This Form 8-K includes forward-looking
statements based on information currently available to management. Such
statements are subject to certain risks and uncertainties. These statements
typically contain, but are not limited to, the terms "anticipate," "expect,"
"believe," "estimate," and similar words. Actual results may differ materially
due to the speed and nature of increased competition and deregulation in the
electric utility industry, economic or weather conditions affecting future sales
and margins, changes in markets for energy services, changing energy and
commodity market prices, replacement power costs being higher than anticipated
or inadequately hedged, maintenance costs being higher than anticipated,
legislative and regulatory changes (including revised environmental
requirements), adverse regulatory or legal decisions, availability and cost of
capital, inability of the Davis-Besse Nuclear Power Station to restart
(including because of any inability to obtain a favorable final determination
from the Nuclear Regulatory Commission) in the fall of 2003, inability to
accomplish or realize anticipated benefits of strategic goals, the ability to
access the public securities markets, further investigation into the causes of
the August 14, 2003, regional power outage and the outcome, cost and other
effects of present and potential legal and administrative proceedings and claims
related to that outage, and other factors discussed from time to time in
FirstEnergy's Securities and Exchange Commission filings, including its annual
report on Form 10-K (as amended) for the year ended December 31, 2002, its Form
10-Q for the quarter ended June 30, 2003 and under "Risk Factors" in the
Prospectus Supplement dated September 12, 2003 to the Prospectus dated August
29, 2003 (which was part of the Registration Statement-SEC File No. 333-103865)
and other similar factors.
