PROSPECTUS SUPPLEMENT SUMMARY
This summary may not contain all of the information that may be important to you. This summary contains basic information about
us and this offering and highlights selected information from this prospectus supplement. The following summary is qualified in its entirety by
the information contained elsewhere or incorporated by reference in this prospectus supplement and the accompanying prospectus. You
should read this entire prospectus supplement and the accompanying prospectus carefully, including the Risk Factors section beginning on
page S-8 of this prospectus supplement, as well as the financial statements and notes to those statements and the documents incorporated by
reference in this prospectus supplement and in the accompanying prospectus, before making an investment decision.
FirstEnergy Corp.
We are a diversified energy holding company. We were organized under the laws of the State of Ohio in 1996. Our principal
business is the holding, directly or indirectly, of all of the outstanding equity of our principal subsidiaries: Ohio Edison Company, The
Cleveland Electric Illuminating Company, The Toledo Edison Company, Pennsylvania Power Company (a wholly owned subsidiary of Ohio
Edison), Jersey Central Power & Light Company, Metropolitan Edison Company, Pennsylvania Electric Company, FirstEnergy Service
Company, FES, and its principal subsidiaries (FirstEnergy Generation, LLC and FirstEnergy Nuclear Generation, LLC), Allegheny Energy
Supply Company, LLC, or AE Supply, Monongahela Power Company, The Potomac Edison Company, West Penn Power Company,
FirstEnergy Transmission, LLC and its principal subsidiaries (American Transmission Systems, Incorporated, Mid-Atlantic Interstate
Transmission, LLC and Trans-Allegheny Interstate Line Company), and Allegheny Energy Service Corporation. In addition, FirstEnergy
holds all of the outstanding equity of other direct subsidiaries including: FirstEnergy Properties, Inc., FirstEnergy Ventures Corp., FENOC,
FELHC, Inc., GPU Nuclear, Inc. and Allegheny Ventures, Inc.
Our principal executive office is located at 76 South Main Street, Akron, Ohio 44308-1890; telephone: (800) 736-3402.
Recent Developments
In January 2017, we announced that AE Supply and Allegheny Generating Company, or AGC, entered into a purchase agreement to
sell 1,572 megawatts of gas/hydro assets to a subsidiary of LS Power Equity Partners III, LP, or LS. The transaction is subject to various
closing conditions, including receipt of regulatory approvals and third-party consents. The consent of Virginia Electric and Power Company,
or VEPCO, is needed for the sale of a portion of AGC's interest in the Bath County pumped hydro facility, as well as agreement among AGC,
LS and VEPCO with respect to certain amendments to the Bath project agreements. While negotiations among the parties and VEPCO
continue, as of the date of this prospectus supplement, no agreement has been reached. On May 24, 2017, AE Supply/AGC and LS exercised a
provision in the purchase agreement that allows either party to terminate the purchase agreement without penalty after 30 days if, among other
things, the parties and VEPCO have not reached agreement on the amendments to the Bath project agreements. Accordingly, if these
conditions have not been satisfied by June 23, 2017, either party may terminate the proposed transaction. We believe the proposed transaction
can be closed, but, in the event the purchase agreement with LS is terminated, we intend to market these assets to other potential buyers.

Maturity
The Series A Notes will mature on July 15, 2022, the Series B Notes will mature on July
15, 2027 and the Series C Notes will mature on July 15, 2047.

https://www.sec.gov/Archives/edgar/data/1031296/000119312517208275/d389830d424b2.htm[6/21/2017 9:53:32 AM]

424B2
will accrue interest at a rate of 3.90% per annum and the Series C Notes will accrue
interest at a rate of 4.85% per annum, in each case subject to adjustment as described
below.

Interest Rate Adjustment
The interest rate payable on the Notes will be subject to adjustment from time to time if
the debt rating assigned to the Notes is downgraded (or subsequently upgraded), as set
forth under "Description of the Notes--Interest Rate Adjustment" below.

Interest Payment Dates
Interest on the Notes will accrue from the date of original issuance and will be payable
semi-annually in arrears on each January 15 and July 15, beginning on January 15, 2018,
and at maturity.

Optional Redemption
The Notes will be redeemable, in whole or in part, at our option, at any time prior to the
date that is two months prior to maturity for the Series A Notes, the date that is three
months prior to maturity for the Series B Notes and the date that is six months prior to
maturity for the Series C Notes, at a "make-whole" redemption price as described under
"Description of the Notes--Optional Redemption" below. After the date that is two
months prior to maturity for the Series A Notes, the date that is three months prior to
maturity for the Series B Notes and the date that is six months prior to maturity for the
Series C Notes, the Notes are redeemable at par. We also will pay accrued and unpaid
interest to, but not including, the date of redemption on the Notes to be redeemed.

Security and Ranking
The Notes will be our unsecured and unsubordinated obligations and will rank equally
with all of our other unsecured and unsubordinated indebtedness. Because we are a holding
company, our obligations under the Notes will be effectively subordinated to all existing
and future liabilities of our subsidiaries. As of March 31, 2017, FirstEnergy Corp. had
approximately $7.2 billion of total indebtedness on a standalone basis. All of such
standalone indebtedness was unsecured and unsubordinated indebtedness. As of March 31,
2017, the subsidiaries of FirstEnergy Corp. had approximately $15.5 billion of
indebtedness outstanding.

Sinking Fund
There is no sinking fund for any series of Notes.

Table of Contents
Limitation on Liens
Subject to certain exceptions, so long as any Notes are outstanding, we may not pledge,
mortgage, hypothecate or grant a security interest in or permit any pledge, mortgage,
security interest or other lien upon, any capital stock of any subsidiary now or hereafter
directly owned by us, to secure any indebtedness without also securing all outstanding
Notes, equally and ratably with that indebtedness, and all other indebtedness entitled to be
similarly secured. See "Risk Factors" in this prospectus supplement and "Description of
Debt Securities--Limitation on Liens" in the accompanying prospectus.

Consolidation, Merger, etc.
Our ability to sell, transfer, convey or otherwise dispose of our properties and assets
substantially as an entirety to any other person is limited. See "Description of Debt
Securities--Consolidation, Merger, Conveyance, Sale or Transfer" in the accompanying
prospectus.

Additional Issuances
We may from time to time, without the consent of the holders of any series of the Notes,
create and issue additional notes having the same terms and conditions as the Notes of such
series so that the additional issuance is consolidated and forms a single series with the
previously issued Notes of such series. Unless such additional notes are issued pursuant to
a "qualified reopening" or are otherwise treated as part of the same "issue" as the Notes for
https://www.sec.gov/Archives/edgar/data/1031296/000119312517208275/d389830d424b2.htm[6/21/2017 9:53:32 AM]

424B2
U.S. federal income tax purposes, such notes shall be issued with a separate CUSIP
number.

Form and Denomination
The Notes will be issued in fully registered form only in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. For more information, see "Description of
the Notes--Book-Entry."

Use of Proceeds
We intend to use the net proceeds to repay our 2.75% Notes, Series A, due 2018, and for
general corporate purposes, including the repayment of our short-term borrowings under
our revolving credit facility. See "Use of Proceeds."

Conflicts of Interest
Affiliates of certain underwriters are lenders under our revolving credit facility. Upon any
application of net proceeds from this offering to repay amounts outstanding under this
facility, each such lender would receive its proportionate share of the amount being repaid.
Those lending affiliates of underwriters who will receive more than 5% of the net proceeds
from this offering in the form of the repayment of such indebtedness will be deemed to
have a "conflict of interest" under the Financial Industry Regulatory, or FINRA, Rule
5121(f)(5)(C)(i). Pursuant to FINRA Rule 5121, the appointment of a qualified
independent underwriter is not necessary in connection with this offering because the
securities offered are investment grade rated or are securities in the same series that have
equal rights and obligations as investment grade rated securities. See "Underwriting
(Conflicts of Interest)--Conflicts of Interest."

(1) "Earnings" for purposes of the calculation of Ratio of Earnings to Fixed Charges have been computed by adding to "Income from
continuing operations" total interest and other charges, before reduction for amounts capitalized and deferred, provision for income taxes
and the estimated interest element of rentals charged to income. "Fixed charges" include interest on long-term debt, other interest
expense, subsidiaries' preferred stock dividend requirements and the estimated interest element of rentals charged to income.

(2) The ratio of earnings to fixed charges was negative for the year ended December 31, 2016, resulting from pre-tax impairment charges of
$10.7 billion. Additional earnings of $9.3 billion would have been required to have a one-to-one ratio of earnings to fixed charges.
