The FirstEnergy Corp. Stock Investment Plan, which we refer to as the Plan, provides a way for registered shareholders and employees of FirstEnergy Corp., which we refer to as FirstEnergy, and its subsidiaries, to purchase shares of FirstEnergy’s common stock. (See Question 4). Registered shareholders or employees who opt to participate in the Plan may:

Cash dividends on common stock and cash investments under the Plan will be used to purchase shares of FirstEnergy common stock which, at our option, either will be newly issued or treasury shares purchased by AST from us or will be purchased on behalf of Plan participants in the open market or in privately negotiated transactions by an independent agent, which we refer to as the Independent Agent, appointed by American Stock Transfer & Trust Company, LLC, which we refer to as AST or the Administrator of the Plan. (See Questions 2 and 13). The price of newly issued or treasury shares acquired under the Plan will be the average of the high and low prices of FirstEnergy common stock as reported on the report of New York Stock Exchange Composite Transactions for the investment date. The price of shares purchased in the open market or in privately negotiated transactions under the Plan will be the weighted average price paid by AST for the shares over the purchase period. (See Question 13). In such cases, the purchase price will include a transaction fee to cover the administrative costs and, if shares are purchased in the open market or in privately negotiated transactions, the fees of AST for its services in executing those purchases. As of the date of this Prospectus, shares to be purchased for participants under the Plan will be newly issued or, if available, treasury shares, and the transaction fee is not to exceed $0.09 per share, but we may change the source of shares at any time without notice to you, subject to legal restrictions on how often we change the source of shares. (See Question 13).

Fees payable by a Plan participant will be added to the purchase price for shares purchased, and deducted from the selling price for shares sold, under the Plan. (See Questions 15 and 23).

This Prospectus describes the provisions of the Plan and should be retained by participants for future reference. Shares of FirstEnergy common stock are traded on the New York Stock Exchange under the ticker symbol “FE.” On September 13, 2016, the last reported sale price of our common stock on the New York Stock Exchange, was $32.70 per share.

Before you invest, you should read this Prospectus carefully and the information referred to under the heading “Where You Can Find More Information.” Also, because investing in our common stock involves risks, you should carefully read and evaluate the risk factors included in our reports and other information that we file with the Securities and Exchange Commission. See “Risk Factors” beginning on page 6.

This Prospectus is not an offer to sell securities, nor is it a solicitation of an offer to buy securities, in any state or country where the offer or sale is not permitted.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this Prospectus. Any representation to the contrary is a criminal offense.

This Prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission, which we refer to as the SEC, relating to the shares of our common stock to be offered and sold pursuant to the Plan.

The registration statement containing this Prospectus, including exhibits to the registration statement, provides additional information about us, the Plan, and the securities offered.

This Prospectus, the registration statement in which it is contained and the information incorporated by reference herein and therein include forward-looking statements based on information currently available to management. Such statements are subject to certain risks and uncertainties. These statements include declarations regarding management’s intents, beliefs and current expectations. These statements typically contain, but are not limited to, the terms “anticipate,” “potential,” “expect,” “forecast,” “target,” “will,” “intend,” “believe,” “project,” “estimate,” “plan” and similar words. Forward-looking statements involve estimates, assumptions, known and unknown risks, uncertainties and other factors that may cause actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements, which may include the following.

Dividends declared from time to time on FirstEnergy’s common stock during any period may in the aggregate vary from prior periods due to circumstances considered by FirstEnergy’s Board of Directors at the time of the actual declarations. A security rating is not a recommendation to buy or hold securities and is subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating.

The foregoing factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements and risks that are included in FirstEnergy’s filings with the SEC, including but not limited to the most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q. New factors emerge from time to time, and it is not possible for management to predict all such factors, nor assess the impact of any such factor on FirstEnergy’s business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statements. FirstEnergy expressly disclaims any current intention to update, except as required by law, any forward-looking statements contained herein as a result of new information, future events or otherwise.

Such risks and uncertainties are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of the described risks actually occur, our business, financial condition or results of operations could be materially adversely affected. In that case, the value or trading price of our common stock could decline, and you could lose part or all of your investment.

This Prospectus and the documents incorporated by reference also contain forward-looking statements that involve risks and uncertainties.

The following questions and answers describe the terms and conditions of the Plan. You should keep this Prospectus for future reference.


Purpose
1.	Q.	What is the purpose of the Plan?

	A.	The purpose of the Plan is to provide registered shareholders and employees of FirstEnergy and its subsidiaries a way to purchase shares of FirstEnergy common stock. Purchases can be made by investing cash when permissible and/or reinvesting cash dividends.

Administration

2.	Q.	Who administers the Plan?

	A.	AST administers the Plan. This includes keeping the Plan records and serving as custodian for shares held in the Plan. If FirstEnergy elects to meet the purchase requirements of participants through purchases of newly issued or, if available, treasury shares as is our intended practice as of the date of this Prospectus, AST is responsible for purchasing FirstEnergy common stock from us for participants’ Plan accounts. If FirstEnergy elects to meet the purchase requirements of participants through purchases of shares of common stock in the open market or in privately negotiated transactions, funds for investment will be deposited promptly into an escrow account for the benefit of Plan participants and the Independent Agent appointed by AST will then act on behalf of participants in buying shares. The Independent Agent will also act on behalf of participants in selling shares. The Independent Agent is not an affiliate of FirstEnergy, its subsidiaries or AST. Neither FirstEnergy, any affiliate of FirstEnergy, AST, nor any participant will exercise any direct or indirect control or influence over (a) the times when, or the prices at which, the Independent Agent purchases or sells shares for the Plan, (b) the amount of the securities to be purchased or sold, (c) the manner in which the securities are to be purchased or sold, or (d) the selection of a broker or dealer (other than the Independent Agent itself) through which the purchase may be executed. FirstEnergy will not change more than once, in any three-month period, the source of the shares to fund the Plan.


		FirstEnergy reserves the right to interpret and regulate the Plan as deemed necessary or desirable. FirstEnergy, AST and the Independent Agent will not be liable for any act done in good faith or for any omission to act in good faith, including, without limitation, any claim of liability arising out of failure to close a participant’s account upon the participant’s death prior to receipt of written notice of such death, or with respect to the prices at which shares of common stock are purchased or sold for the participant’s account and the times when such purchases and sales are made, or with respect to any loss or fluctuation in the market value after the purchase or sale of such shares. However, FirstEnergy, AST and the Independent Agent shall not be relieved from any liability imposed under any federal, state, or other applicable securities law that cannot be waived.

3.	Q.	Who should I contact with questions concerning the Plan?

	A.	You may call AST toll-free at (800) 736-3402 between the hours of 8:00 a.m. — 8:00 p.m. Eastern Time, Monday through Friday, or visit AST’s website at www.amstock.com. You also may write AST at the following addresses: For inquiries you may write: FirstEnergy Corp. c/o American Stock Transfer & Trust Company, LLC 6201 15th Avenue Brooklyn, New York 11219 Attention: Shareholder Relations Department For transaction processing you may write: FirstEnergy Corp. c/o American Stock Transfer & Trust Company, LLC Attention: FirstEnergy Corp. P. O. Box 2016 New York, NY 10272-2016

Participation

4.	Q.	Who is eligible to participate in the Plan?

	A.	All registered shareholders and employees of FirstEnergy and its subsidiaries are eligible to participate. Regulations in certain countries may limit or prohibit participation in this type of plan. Accordingly, persons residing outside of the United States who wish to participate in the Plan should first determine whether


		they are subject to any governmental regulation prohibiting their participation. FirstEnergy reserves the right to restrict or terminate participation in the Plan if it believes such participation may be contrary to the general intent of the Plan or in violation of applicable law.

5.	Q.	How do I enroll in the Plan?

	A.	Shareholders — Registered shareholders can enroll by completing and signing a Stock Investment Plan Enrollment Form available from AST at (800) 736-3402 or online at www.amstock.com and mailing it to the transaction processing address listed in Question 3. You also may enroll online at www.amstock.com. You need to know your AST 10-digit account number and your social security number to gain access to your account. Employees — Employees of FirstEnergy and its subsidiaries can enroll by completing and signing a Stock Investment Plan Enrollment Form available from AST at (800) 736-3402 or online at www.amstock.com and mailing it to the transaction processing address listed in Question 3. If voluntary payroll deductions are not desired, this form must be accompanied by a check or an authorization of monthly automatic electronic cash investments for direct debit from your checking or savings account. For the protection of participants, AST discourages sending endorsed second-party checks and no longer accepts cash or money orders. Checks must be drawn on a U.S. bank and be payable in U.S. funds. If voluntary payroll deductions are desired, an employee may enroll or commence payroll deductions by signing and completing a Stock Investment Plan Payroll Deduction Authorization and Stock Investment Plan Enrollment Form available on the FirstEnergy employee portal and return the form to the Corporate Department. Enrollment by participants that are employees, affiliates and Section 16 officers of FirstEnergy must be made in compliance with FirstEnergy’s Insider Trading Policy, which, among other things, provides that such participants may not trade in shares of FirstEnergy common stock if in possession of material, non-public information about FirstEnergy. Beneficial Owners (how to become a registered shareholder) — If you are the beneficial owner of shares of our common stock that are held in record name by a broker or nominee and you wish to participate in the Plan, you must become a shareholder of record by having at least one share of our common stock transferred to your name. Neither FirstEnergy, nor AST is responsible for any fees that may be charged by any broker or bank as a result of becoming a registered shareholder.


6.	Q.	What dividend payment options are provided under the Plan and how can I change how my dividends are paid?

	A.	The Plan provides complete flexibility in regard to how dividends are paid. You are asked to provide payment instructions by completing both Parts (A) and (B) of the Dividend Reinvestment and Payment Instructions Section of the Stock Investment Plan Enrollment Form. Part (A) contains payment instructions for shares that are held by you in certificate form. Part (B) contains payment instructions for shares that are held by AST in an account for you. Dividend payment options are as follows: Reinvest dividends on all shares — All dividends are reinvested to purchase shares of FirstEnergy common stock. Pay cash dividends on all shares — All dividends are paid in cash. Pay cash dividends on portion of shares — You may elect to have a portion of dividends paid in cash and reinvest the remaining dividends to purchase shares of FirstEnergy common stock by selecting the number of shares, the percent, or the dollar amount of dividends to be paid in cash. If you choose this option, under the Economic Emergency Stabilization Act, which became law in 2008, you must reinvest at least 10% of your dividend distribution each dividend period. If you elect to receive all or a portion of your dividends in cash, your cash dividends may be deposited directly into your checking, savings, or credit union account at any financial institution that accepts electronic direct deposits. Receiving your payments by direct deposit ensures that the funds will be deposited into your bank account on the payment date. If you are interested in direct deposit of dividends, you should complete the appropriate section on the Stock Investment Plan Enrollment Form or call AST, or visit AST online at www.amstock.com for a Direct Dividend Deposit Authorization Agreement. You may change how your dividends are paid at any time by completing a new Stock Investment Plan Enrollment Form.

7.	Q.	When must my Stock Investment Plan Enrollment Form be received by AST?

	A.	For dividends to be reinvested, your Stock Investment Plan Enrollment Form must be received by AST on or before the record date for the dividend payment; otherwise, reinvestment of dividends will start with the next succeeding dividend payment. The dividend record and payment dates for common stock dividends, which must be declared by FirstEnergy’s board of directors, are expected to be as follows: Record Dates — Fifth business day of February, May, August, November


		Payment Dates — March 1, June 1, September 1, December 1 For initial cash investments, a properly completed Stock Investment Plan Enrollment Form and the initial cash payment must be received by AST prior to a cash investment date, which is expected to be the 1st day of each month. Otherwise, the investment will be made on the next succeeding cash investment date. See Question 11 for additional information. Dividends declared from time to time on FirstEnergy’s common stock during any period may in the aggregate vary from prior periods due to circumstances considered by FirstEnergy’s Board of Directors at the time of the actual declarations. FirstEnergy can provide no assurance regarding the timing or amount of any such dividends or whether funds will be legally available to pay dividends at any given time or that, if funds are available, the Board of Directors will declare a dividend.

Dividend Reinvestment

8.	Q.	What is meant by dividend reinvestment?

	A	If you elect to reinvest all or a portion of your cash dividends, AST will take those cash dividends and purchase shares of FirstEnergy common stock for you. The amount reinvested will be reduced by (1) any amount that is required to be withheld under any applicable tax or other statutes and (2) applicable transaction fees. See the “Purchases” section for more detailed information.

Cash Investments

9.	Q.	Who is eligible to make cash investments?

	A.	All persons and entities that are eligible to participate in the Plan are eligible to make cash investments. See Question 4 for Plan eligibility requirements. Purchases of shares by participants that are employees, affiliates and Section 16 officers of FirstEnergy must be made in compliance with FirstEnergy’s Insider Trading Policy, which, among other things, provides that such participants may not trade in shares of FirstEnergy common stock if in possession of material, non-public information about FirstEnergy.



10.	Q.	What are the minimum and maximum cash investments?

	A.	The minimum cash investment is $25 per payment; however, for employees who elect to use payroll deduction to make cash investments, the minimum deduction is $10 per pay period. The maximum amount of cash investments is $100,000 per calendar year, per participant.

11.	Q.	How do I make a cash investment or change a cash investment?

	A.	If you are a registered shareholder or employee but not a current Plan participant, you must enclose a check or sign up for monthly automatic electronic cash investments for direct debit from your checking or savings account with your Stock Investment Plan Enrollment Form, or you may choose to set up an account online at www.amstock.com and click on “Invest online” and then follow the prompts. If you are a current Plan participant, you can make a cash investment by sending a check or by signing up for automatic electronic cash investments for direct debit from your checking or savings account, as discussed below. When sending a check, you should attach a Transaction Request Form, which is attached to your Plan statements. You may also send a check without a Transaction Request Form; however, your stock registration or tax identification number should be included on your check for account identification purposes, along with a cover letter requesting that the check be used to purchase common stock of FirstEnergy. If you are a current Plan participant and an employee, you may authorize automatic cash investments by completing a Stock Investment Plan Payroll Deduction Authorization and Stock Investment Plan Enrollment Form available on the FirstEnergy employee portal and return the form to the Corporate Department. All checks should be made payable to “American Stock Transfer & Trust Company, LLC” and sent to FirstEnergy Corp., c/o American Stock Transfer & Trust Company, LLC, P. O. Box 2016, New York, NY 10272-2016 Attn.: Plan Administration Department. For the protection of participants, AST discourages sending endorsed second-party checks and no longer accepts cash or money orders. Checks must be drawn on a U.S. bank and be payable in U.S. funds. You may authorize monthly automatic electronic cash investments by completing the appropriate section on the Stock Investment Plan Enrollment Form, which is available from AST at (800) 736-3402 or online at www.amstock.com. This


		enables you to make regular investments, if you choose, without writing and mailing checks. If you authorize automatic electronic cash investments, funds will be withdrawn from your bank or credit union account on or about the 25th day of each month and will be invested on the next investment date following the withdrawal. Your bank, savings association or credit union must be a member of the National Automated Clearinghouse Association. You may change the amount automatically withdrawn or the financial institution at any time by completing a new Stock Investment Plan Enrollment Form, and you may stop automatic electronic cash investments by notifying the Plan Administration Department in writing. Employees may change the amount of any automatic payroll deduction by completing a new Stock Investment Plan Payroll Deduction Authorization and Stock Investment Plan Enrollment Form available on the FirstEnergy employee portal and returning the form to the Corporate Department. Employees may stop automatic payroll deductions at any time by notifying the Corporate Department. Cash investments, pending purchase of common stock through the Plan, will be credited to your Plan account. No interest will be paid to you on cash held for investment. You may request the return of a cash investment upon written request received by AST not later than 48 hours prior to the applicable investment date. If your check or direct debit is returned as unpaid, AST will debit the uninvested cash payment from your account. If, however, the investment has been made, then AST, through the Independent Agent, will sell the shares that have been purchased to satisfy the return check or direct debit. If the sale of the shares purchased is not sufficient to satisfy the return check, then additional shares will be sold from your account. Additionally, shares may be sold from your account to satisfy any return check fees.

Investment Dates

12.	Q.	When are the investment dates for Plan purchases?

	A.	Investment dates for reinvested dividends are the dividend payment dates. Payment dates for common stock dividends are expected to be March 1, June 1, September 1, and December 1. Investment dates for cash investments are expected to be the 1st day of each month. A cash investment must be received by AST by the business day before the investment date in order to be invested on such investment date. Otherwise, the cash investment will be held by AST and invested on the next investment date.


		In order to receive dividends on shares of common stock purchased with a cash investment through the Plan, the shares must be purchased on an investment date prior to the dividend record date and must settle by or on the record date. Record dates for common stock dividends are expected to be the fifth business day of February, May, August, and November.

Purchases

13.	Q.	What is the price of shares purchased under the Plan?

	A.	Reinvested dividends and cash investments will be used to purchase shares of FirstEnergy common stock which, at the option of FirstEnergy, will be either newly issued or treasury shares purchased by AST from FirstEnergy or will be purchased on behalf of Plan participants in the open market or in privately negotiated transactions by AST through the Independent Agent. The determination of the source of shares of common stock to be used for purchases under the Plan will be made at the discretion of FirstEnergy. In this regard, FirstEnergy will receive all of the proceeds resulting from the purchase of newly issued or treasury shares under the Plan, excluding any transaction fees. However, in certain circumstances, shares of common stock purchased for participants under the Plan may be purchased in the open market or in privately negotiated transactions. As of the date of this Prospectus, shares of common stock purchased for participants under the Plan will be newly issued or, if available, treasury shares purchased by AST from FirstEnergy. FirstEnergy may change the source of the shares of common stock to be used for purchases under the Plan at any time without notice to you. FirstEnergy will not change more than once in any three-month period the source of the purchase of the shares. When shares to be purchased are satisfied by newly issued or treasury shares purchased by AST from FirstEnergy, the price will be the average of the high and low prices of FirstEnergy’s common stock, as reported in the New York Stock Exchange Composite Transactions for the investment date (or the next preceding day on which FirstEnergy common stock is traded on the New York Stock Exchange, if it is not traded on the investment date), plus a transaction fee that is not to exceed $0.09 per share. When shares are purchased in the open market or in privately negotiated transactions, the purchase price per share will be the weighted average price of the aggregated shares purchased by AST during the purchase period plus a transaction fee that is not to exceed $0.09 per share. The purchase period may begin no more than three business days before the investment date, and should be completed no more than 10 days after the investment date, although it could be longer. The


		length of the purchase period is affected by the amount of funds to be invested, the availability of shares in the open market or in privately negotiated transactions, and market conditions. Purchases of shares pursuant to cash payments will be completed within 35 days after receipt of cash payments, or else the cash payment will be returned to the Plan participant. AST will combine the funds of all participants for the purpose of executing purchase transactions. For open market purchases, if shares cannot be purchased with respect to an investment date due to the inability to purchase shares during the purchase period, or if any purchase is deemed to be otherwise inadvisable by AST, FirstEnergy, and/or the Independent Agent, the dividends and cash investments that otherwise would have been invested will be paid or returned, as the case may be, by AST issuing checks to the affected participants without interest.

14.	Q.	How many shares of common stock will be purchased?

	A.	The number of shares (including any fraction of a share) of common stock purchased for you will be determined by dividing the total amount of the cash dividend and/or cash investment to be invested for you on the investment date by the purchase price. All shares purchased under the Plan are held by AST and credited to your Plan account until such time as you request the withdrawal of shares from your Plan account. Because only the Independent Agent may direct the time or price thereof, when shares are purchased in the open market or in privately negotiated transactions, neither we nor AST can exercise, directly or indirectly, control or influence over the number of shares to be purchased in the open market or in privately negotiated transactions.

15.	Q.	Do I incur any fees for shares purchased under the Plan?

	A.	Yes. There is a transaction fee for each share purchased to cover any applicable brokerage commissions and administrative costs of the Plan. This transaction fee is not to exceed $0.09 per share; however, there is currently no maximum amount set for the Plan’s fees. Plan participants will receive advance written notice if there is a need to charge a transaction fee of greater than $0.09 per share due to increased administrative costs or broker commissions, as applicable.

Safekeeping Option for Common Stock Certificates

16.	Q.	What is the purpose and advantages of the safekeeping option?

	A.	The purpose of the Plan’s safekeeping option is to enable you to deposit any FirstEnergy common stock certificates into the Plan for safekeeping. The certificates are canceled, and the shares are credited to your Plan account. The


		shares are shown on dividend checks and/or Plan account statements and otherwise treated in the same manner as shares purchased through the Plan. Benefits of the Plan’s safekeeping option include: you do not have to worry or bear the cost of protecting stock certificates or replacing certificates due to loss, theft, or destruction; you can request that a certificate for whole shares be issued at no cost to you at any time; and because shares held in safekeeping are treated in the same manner as shares purchased through the Plan, you may sell them conveniently through the Plan.

17.	Q.	How do I use the safekeeping option?

	A.	At the time of Plan enrollment, you may take advantage of the safekeeping option by sending your certificate(s), unsigned, to FirstEnergy Corp., c/o American Stock Transfer & Trust Company, LLC, P.O. Box 2016, New York, NY 10272-2016, with a Stock Investment Plan Enrollment Form. Or, at any time after enrollment, you may send your certificate(s), unsigned, with a signed letter of instruction requesting that AST hold the shares in safekeeping and stating whether the dividends for shares being sent are to be reinvested or paid in cash.

Sales, Certificate Withdrawals, Transfers and Closing Plan Accounts

18.	Q.	How do I receive a certificate for, or sell a portion of, my Plan shares?

	A.	To receive a certificate for, or to sell a portion of, the shares credited to your Plan account, you must notify AST of the number of whole shares to be issued in certificate form or to be sold. You can choose to process your request either online at www.amstock.com, by calling (800) 736-3402 and using the Voice Response System, or by mail.

19.	Q.	How do I close my Plan account?

	A.	You may close your Plan account at any time. To close a Plan account, you must notify AST and provide instructions as to whether a certificate is to be issued, the shares are to be sold, or both. If both, the number of whole shares for which a certificate is to be issued must be specified so that the remainder of the shares can be sold. When requested to issue a certificate only, or if no instructions are provided, AST will issue a certificate for all whole shares credited to the account and a check for the value of any fraction of a share. The price of the shares sold, including any fractional shares, will be the weighted average price of the aggregated shares sold by the Independent Agent or broker less a transaction fee not to exceed $0.09 per share.



20.	Q.	How long does it take to withdraw certificates or close my Plan account?

	A.	It normally takes less than three business days from the time AST receives a request for an account to be closed or a certificate to be issued. If your request to terminate your Plan account is received more than three business days prior to any dividend payable date, then that dividend will be paid to you in cash. If your request is received less than three business days prior to a dividend payable date, then that dividend will be reinvested. However, all subsequent dividends will be paid out in cash on all balances. Upon request, AST can issue a certificate for whole shares and sell the fractional shares or sell all whole and fractional shares in your Plan account, and then close your account by issuing another certificate for or selling the additional shares purchased after the shares are credited to your Plan account. The Plan does not provide for the automatic issuance of certificates after a purchase, and certificates for fractional shares will not be issued under any circumstances. Certificates representing Plan shares will be issued in the name in which your account is registered.

21.	Q.	May a participant transfer all or a part of the participant’s shares held in the Plan to another person?

	A.	You may transfer ownership of all or part of your shares held in the Plan through gift, private sale or otherwise by mailing to the Administrator of the Plan at the address in Question 3 a properly executed stock assignment, along with a letter with specific instructions regarding the transfer. Requests for transfer of shares held in the Plan are subject to the same requirements as the transfer of common stock certificates, including the requirement of a medallion signature guarantee on the stock assignment. The Administrator of the Plan will provide you with the appropriate forms upon request. If any stock certificates bearing a restrictive legend are contained in your Plan account, the Administrator of the Plan will comply with the provisions of such restrictive legend before effecting a sale or transfer of such restricted shares.

22.	Q.	Once a Plan Participant requests to sell Plan shares, when will the Plan shares be sold and at what price?

	A.	Participants’ requests to sell Plan shares will be aggregated and sold as often as daily but at least weekly, depending on the volume. You may process a request online at www.amstock.com, by calling (800) 736-3402 and using the Voice Response System or through the mail by sending your request to the transaction


		processing address in Question 3. AST will place a market order with the Independent Agent or broker designated by AST, who will sell the shares as soon as practicable. None of FirstEnergy, AST, or any participant will have any authority or power to direct the time or price at which shares may be sold. Typically, the shares are sold through the exchange on which the common shares of FirstEnergy are traded. Depending on the number of FirstEnergy shares to be sold and current trading volume, sale transactions may be completed in multiple transactions and over the course of more than one day. All sales are subject to market conditions, system availability, restrictions and other factors. The actual sale date, time or price received for any shares sold through the Plan cannot be guaranteed. The price of the shares sold will be the weighted average price of the aggregated shares sold by the Independent Agent or designated broker less a transaction fee not to exceed $0.09 per share. A check for sale of the shares, less the transaction fee, generally will be mailed to the participant three business days after the shares are sold. Sales of shares by participants that are employees, affiliates and Section 16 officers of FirstEnergy must be made in compliance with FirstEnergy’s Insider Trading Policy, which, among other things, provides that such participants may not trade in shares of FirstEnergy common stock if in possession of material, non-public information about FirstEnergy.

23.	Q.	Will I incur any fees for shares sold under the Plan?

	A.	Yes. There is a transaction fee for each share sold to cover brokerage commissions and administrative costs of the Plan. This transaction fee is not to exceed $0.09 per share; however, there is currently no maximum amount set for the Plan’s fees. Plan participants will receive advance written notice if there is a need to charge a transaction fee of greater than $0.09 per share due to increased administrative costs or broker commissions.

Plan Account Statements

24.	Q.	Will I receive Plan account statements?

	A.	If you reinvest some or all of your dividends, you will receive a Plan statement as soon as practicable after each dividend payment date. You also will receive a Plan statement as soon as practicable after any investment date that you invest cash. The Administrator of the Plan will also send you a Plan statement after any


		transfer, sale or withdrawal of Plan shares. Plan statements provide participants with records of their purchases and sales and other important information and should be retained for tax purposes. If you receive a dividend check for some or all of your dividends, you will receive account information on the stub attached to the check. In addition to periodic account statements, a Plan account history report is available at any time on line at www.amstock.com. You need to know your AST 10 digit account number and your social security number to gain access to your account. Once you have accessed your account online you can follow the heading on the side bar and access your account history detail.

Tax Consequences

25.	Q.	What are the U.S. federal income tax consequences of participation in the Plan?

	A.	The following is a summary of certain U.S. federal income tax consequences regarding the Plan and is provided solely as general guidance. This summary is not a complete description of all of the tax consequences that may be relevant to you in light of your particular circumstances, or if you are a type of investor who is subject to special treatment under U.S. federal income tax laws (including, without limitation, insurance companies, partnerships, tax-exempt organizations, broker dealers, foreign corporations, and persons who are not citizens or residents of the United States). This summary is based on current tax law and may be affected by changes in tax laws and regulations. YOU ARE ADVISED TO CONSULT YOUR OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF PARTICIPATING IN THE PLAN (INCLUDING THE EFFECT OF U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS AND ANY APPLICABLE U.S. TAX WITHHOLDING LAWS). In general, the amount of cash dividends paid by FirstEnergy will be includable in your income and reportable through a Form 1099-DIV even if reinvested under the Plan. When your dividends are reinvested to acquire shares (including any fractional share) directly from FirstEnergy, you will be treated as having received on the dividend payment date a taxable dividend in an amount equal to the fair market value of our common stock purchased for your account under the Plan. When your dividends are reinvested to acquire shares (including any fractional share) purchased in open market or in privately negotiated transactions, you will be treated as having received a taxable dividend equal to the amount of cash dividends used to make those purchases, including the amount equal to the

transaction fees or commissions. If after the date of this Prospectus FirstEnergy chooses to fund the amount of the transaction fees for its participants, you will be treated as having received an additional taxable dividend in an amount equal to the transaction fees or commission.

FirstEnergy will report to you for U.S. federal income tax purposes the dividends to be credited to your account. Such information will also be furnished to the Internal Revenue Service to the extent required by law.

The tax basis of shares acquired through the reinvestment of dividends pursuant to the Plan generally will equal the amount of distributions you are treated as receiving, as described above. The tax basis of shares purchased with optional cash investments will be equal to the purchase price of those shares. The tax basis of shares purchased in the open market or in privately negotiated transactions to satisfy Plan requirements will be increased by the amount of any transaction fees paid by FirstEnergy with respect to such purchases on your behalf. As of the date of this Prospectus, FirstEnergy does not fund the transaction fees for its participants. The holding period for shares acquired under the Plan (including any fractional share) generally will begin on the date after the date on which the shares are purchased and credited to your Plan account, regardless of the source of purchase. Consequently, shares of FirstEnergy common stock acquired at different times will have different holding periods.

You will not realize any taxable income when you receive certificates for whole shares of stock credited to your accounts, either upon a request for a certificate or upon withdrawal from or termination of the Plan. You will generally, however, realize capital gain or loss when whole shares acquired under the Plan are sold or exchanged either by you or by the Administrator of the Plan, on your behalf. You also realize capital gain or loss when you receive cash payments from the sale of any fractional share upon withdrawal from or termination of the Plan. Such gain or loss on the sale of whole or fractional shares will be long-term or short-term depending on the holding period of the shares. The amount of any such capital gain or loss will be the difference between your amount realized from the sale of the shares and your adjusted basis in such shares. Failure to certify your taxpayer identification number may result in backup withholding being applied to reduce proceeds from sale or at the time of withdrawal from or termination of the Plan.


Other Information

26.	Q.	What happens if FirstEnergy issues a stock dividend or declares a stock split?

	A.	Any shares of common stock distributed by FirstEnergy as a stock dividend, or as a stock split, on shares credited to your Plan account or in book-entry form or on shares you hold in certificated form, will be credited to your Plan account. Transaction processing may either be curtailed or suspended until the completion of any stock dividend, stock split or similar corporate action.

27.	Q.	If FirstEnergy has a rights offering, how will the rights on Plan shares be handled?

	A.	Rights on shares held by you in certificated form and on any shares, both whole and fractional, credited to your Plan account or in book-entry form will be mailed directly to you in the same manner as to shareholders not participating in the Plan.

28.	Q.	How will shares I hold in the Plan be voted at meetings of shareholders?

	A.	You will receive or have electronic access to FirstEnergy’s proxy materials, including a proxy card, which will enable you to vote both shares credited to your Plan account and shares held by you in certificated form.

29.	Q.	Can shares credited to my Plan account be pledged?

	A.	No. Shares credited to your Plan account may not be pledged. If you wish to pledge such shares you must request the issuance of a stock certificate for such shares.

30.	Q.	Who bears the risk of investment decisions?

	A.	Neither FirstEnergy, nor AST will provide any advice, make any recommendations, or offer any opinion with respect to whether or not you should purchase or sell shares under or otherwise participate in the Plan. You must make independent investment decisions based on your own judgment and research. By participating in the Plan, you accept the risks as well as the benefits of the Plan, including the risk of loss on your investment. Additionally, FirstEnergy, AST and the Independent Agent will not be liable for any act done in good faith or for any omission to act in good faith, including, without limitation, any claim of liability arising out of failure to close a participant’s account upon the participant’s death prior to receipt of written notice of such death, or with respect to the prices at which shares of common stock are purchased or sold for the participant’s account and the times when such purchases and sales are made, or with respect to any loss or fluctuation in the market value


		after the purchase or sale of such shares. However, FirstEnergy, AST and the Independent Agent will not be relieved from any liability imposed under any federal, state, or other applicable securities law that cannot be waived. FirstEnergy and AST will not be liable for any claims(s) made more than 30 days after any instruction to purchase or sell shares was given.

31.	Q.	Who bears the risk of market price fluctuations affecting the value of Plan shares?

	A.	Each individual participant in the Plan bears the risk of market price changes affecting the value of the stock. FirstEnergy cannot assure you of a profit or protect you against a loss on any shares you hold, purchase, or sell under the Plan. Additionally, FirstEnergy’s share price may fluctuate between the time the purchase and/or sale request is received and the time the purchase or sale is completed. AST will not be liable for any claim arising out of failure to purchase or sell on a certain date or at a specific price. Neither FirstEnergy, AST nor any of their affiliates will provide any investment recommendations or investment advice with respect to transactions made through the Plan. This risk should be evaluated by the participant and is a risk that is borne solely by the participant. You should carefully read and evaluate the risk factors included in FirstEnergy’s reports and other information that FirstEnergy files with the SEC.

32.	Q.	What happens if my account balance falls below a full share?

	A.	AST reserves the right to close any account if the share balance falls below one full share. You will receive a check for the sale of the fractional share less a service fee which is not to exceed $0.09 per share as of the date of this Prospectus.

33.	Q.	Can my participation in the Plan be terminated?

	A.	Yes. After mailing written notice to you, your participation in the Plan may be terminated for any reason, including if your ownership interest is less than one full share. If your participation has been terminated, you will receive (1) a certificate for any or all of the whole shares of common stock credited to your account, (2) any uninvested dividend or cash investment credited to your account and (3) a check for the cash value of any fraction of a share of common stock credited to your account. The cash value for such fraction of a share sold will be the weighted average price of the aggregated fractions of shares sold by the Independent Agent or designated broker less a transaction fee not to exceed $0.09 per share.

34.	Q.	May the Plan be changed, suspended, or discontinued?

	A.	FirstEnergy reserves the right, for any reason, to modify, suspend, or terminate any provision of the Plan, or the Plan as a whole, at any time. All participants will

receive notice of any such modification, suspension, or termination. Typically, notice will be provided prior to the effectiveness of the applicable modification, suspension, or termination. However, notices of suspension or termination caused by the inability to purchase or inadvisability of purchasing shares may be given after the fact. If the Plan is suspended, similarly FirstEnergy may, for any reason, reinstate the Plan at any time. Again, notice will be given to participants of the reinstatement, and such notice may be given before or after the fact.

Upon any termination of the Plan by FirstEnergy, you will receive (1) a certificate for all of the whole shares of common stock credited to your account, (2) any uninvested dividend or cash investment credited to your account, and (3) a check for the cash value of any fraction of a share of common stock credited to your account. The cash value for such fraction of a share sold will be the weighted average price of the aggregated shares sold by the Independent Agent or designated broker less a transaction fee, which is not to exceed $0.09 per share as of the date of this Prospectus.

If you have questions concerning the Plan or FirstEnergy, please call AST at 1-800-736-3402.

We will receive proceeds from the sale of our common stock pursuant to the Plan only to the extent that those sales are of newly issued or treasury shares of our common stock purchased by AST from us, excluding any transaction fees. We will not receive any proceeds from open market purchases or purchases in privately negotiated transactions. As of the date of this Prospectus, shares of common stock purchased for participants under the Plan will be newly issued or, if available, treasury shares purchased by AST from us. The proceeds from the sale to the Plan of any newly issued or treasury stock will be used to meet working capital and capital expenditure requirements and for other corporate purposes. As of the date of this Prospectus, we are unable to estimate the amount of proceeds.

Certain provisions of our Amended Articles of Incorporation, as amended, which we refer to as our Amended Articles of Incorporation and Amended Code of Regulations, as amended, which we refer to as our Amended Code of Regulations, are summarized or referred to below. The summaries are merely an outline, do not purport to be complete, do not relate to or give effect to the provisions of statutory or common law, and are qualified in their entirety by express reference to our Amended Articles of Incorporation and Amended Code of Regulations.

We are authorized by our Amended Articles of Incorporation to issue 490,000,000 shares of common stock, par value $0.10 per share, of which 425,665,423 shares were issued and outstanding as of September 6, 2016. The common stock outstanding as of the date of this Prospectus is, and the common stock offered pursuant to this Prospectus will be, fully paid and non-assessable.

We are also authorized by our Amended Articles of Incorporation to issue 5,000,000 shares of preferred stock, par value $100 per share, of which none are issued and outstanding as of the date of this Prospectus. Our Amended Articles of Incorporation give our board of directors authority to issue preferred stock from time to time in one or more classes or series and to fix the designations, powers, preferences, limitations and relative rights of any series of preferred stock that we choose to issue, including, without limitation, dividend rates, conversion rights, voting rights, terms of redemption and liquidation preferences and the number of shares constituting each such series. Such preferred stock could be issued with terms that could delay, defer or prevent a change of control of FirstEnergy. Prior to the issuance of a new series of preferred stock, we will amend our Amended Articles of Incorporation, designating the stock of that series and the terms of that series.

Subject only to any prior rights and preferences of any shares of our preferred stock that may in the future be issued and outstanding, the holders of the common stock are entitled to receive dividends when, as and if declared by our board of directors out of legally available funds. There can be no assurance that funds will be legally available to pay dividends at any given time or that, if funds are available, the board of directors will declare a dividend.

In the event of our dissolution or liquidation, the holders of our common stock will be entitled to receive, pro rata, after the prior rights of the holders of any issued and outstanding shares of our preferred stock have been satisfied, all of our assets that remain available for distribution after payment in full of all of our liabilities.

The holders of our common stock are entitled to one vote on each matter submitted for their vote at any meeting of our shareholders for each share of common stock held as of the record date for the meeting. Under our Amended Articles of Incorporation, the voting rights, if any, of our preferred stock may differ from the voting rights of our common stock. The holders of our common stock are not entitled to cumulate their votes for the election of directors.

Approval of at least 80% of the voting power of our outstanding shares must be obtained in order to amend or repeal, or adopt any provision inconsistent with the provisions of our Amended Articles of Incorporation dealing with, among other things:

In addition, the approval of at least 80% of the voting power of our outstanding shares must be obtained to amend or repeal the provisions of our Amended Code of Regulations dealing with, among other things:

Adoption of amendments to our Amended Articles of Incorporation (other than those requiring 80% approval as specified above), adoption of a plan of merger, consolidation or reorganization, authorization of a sale or other disposition of all or substantially all of our assets not made in the usual and regular course of its business or adoption of a resolution of dissolution, and any other matter that would otherwise require a two-thirds approving vote, require the approval of two-thirds of the voting power of our outstanding shares, unless our board of

directors provides otherwise by resolution, in which case these matters will require the approval of a majority of the voting power of our outstanding shares and the approval of a majority of the voting power of any shares entitled to vote as a class.

Several provisions of the Ohio Revised Code, or ORC, may make it more difficult to acquire us by means of a tender offer, open market purchase, proxy fight or otherwise. These provisions include Chapter 1704 (Business Combinations), Section 1701.831 (Control Share Acquisitions) and Section 1707.041 (Control Bids). The ORC’s Business Combination, Control Share Acquisition and Control Bids provisions are set forth in summary below. This summary does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all sections of the ORC.

Chapter 1704 of the ORC applies to a broad range of business combinations between an Ohio corporation and an interested shareholder. The Ohio law definition of “business combination” includes mergers, consolidations, combinations or majority share acquisitions. An “interested shareholder” is defined as a shareholder who, directly or indirectly, exercises or directs the exercise of 10% or more of the voting power of the corporation in the election of directors.

Chapter 1704 restricts corporations from engaging in business combinations with interested shareholders, unless the articles of incorporation provide otherwise, for a period of three years following the date on which the shareholder became an interested shareholder, unless the directors of the corporation have approved the business combination or the interested shareholder’s acquisition of shares of the corporation prior to the date the shareholder became an interested shareholder. After the initial three-year moratorium, Chapter 1704 prohibits such transactions absent approval by the directors of the interested shareholder’s acquisition of shares of the corporation prior to the date that the shareholder became an interested shareholder, approval by disinterested shareholders of the corporation or the transaction meeting certain statutorily defined fair price provisions.

Under Section 1701.831 of the ORC, unless the articles of incorporation, the regulations adopted by the shareholders, or the regulations adopted by the directors pursuant to division (A)(1) of Section 1701.10 of the ORC provide otherwise, any control share acquisition of a corporation can only be made with the prior approval of the corporation’s disinterested shareholders. A “control share acquisition” is defined as the acquisition, directly or indirectly, by any person of shares of a corporation that, when added to all other shares of that corporation in

respect of which the person may exercise or direct the exercise of voting power, would enable that person, immediately after the acquisition, directly or indirectly, alone or with others, to exercise levels of voting power of the corporation in the election of directors in any of the following ranges: at least 20% but less than 33¹⁄₃%; at least 33¹⁄₃% but no more than 50%; or more than 50%.

We have not opted out of the application of either Chapter 1704 or Section 1701.831.

Section 1707.041 of the ORC regulates certain “control bids” for corporations in Ohio with certain concentrations of Ohio shareholders and permits the Ohio Division of Securities to suspend a control bid if certain information is not provided to offerees, the subject corporation and the Ohio Division of Securities. Control bids include the purchase of or offer to purchase any equity security of such a corporation from a resident of Ohio if, after the purchase of that security, the offeror would be directly or indirectly the beneficial owner of more than 10% of any class of issued and outstanding equity securities of the corporation. Information that must be provided in connection with a control bid includes a statement of any plans or proposals that the offeror, upon gaining control, may have to liquidate the subject corporation, sell its assets, effect a merger or consolidation of the corporation, establish, terminate, convert, or amend employee benefit plans, close any plant or facility of the subject corporation or of any of its subsidiaries or affiliates, change or reduce its work force or the work force of any of its subsidiaries or affiliates, or make any other major change in the corporation’s business, corporate structure, management personnel or policies of employment.

Some of the supermajority provisions of our Amended Articles of Incorporation and Amended Code of Regulations and the rights or the provisions of Ohio law described above, individually or collectively, may discourage, deter, delay or impede a tender offer or other attempt to acquire control of FirstEnergy even if the transaction would result in the shareholders receiving a premium for their shares over current market prices or if the shareholders otherwise believe the transaction would be in their best interests.

In addition, our Amended Code of Regulations contains certain advance notice provisions for which shareholders must comply in order to bring business before an annual meeting of shareholders or nominate candidates for our board of directors.

Shareholders must provide us advance notice of the introduction by them of business at annual meetings of our shareholders. For a shareholder to properly bring a proposal before an

annual meeting, the shareholder must follow the advance notice procedures described in our Amended Code of Regulations. In general, the shareholder must deliver a written notice to our Corporate Secretary describing the proposal and the shareholder’s interest in the proposal not less than 30 nor more than 60 calendar days prior to the annual meeting. However, in the event public announcement of the date of the annual meeting is not made at least 70 calendar days prior to the date of the annual meeting, notice by the shareholder to be timely must be so received not later than the close of business on the 10th calendar day following the day on which public announcement is first made of the date of the annual meeting.

Shareholders can nominate candidates for our board of directors. However, a shareholder must follow the advance notice procedures described in Regulation 14(c) of our Amended Code of Regulations. In general, a shareholder must submit a written notice of the nomination that includes the information required by our Amended Code of Regulations to our Corporate Secretary not less than 30 nor more than 60 calendar days prior to the annual meeting of shareholders. However, in the event public announcement of the date of the annual meeting is not made at least 70 calendar days prior to the date of the annual meeting, notice by the shareholder to be timely must be so received not later than the close of business on the 10th calendar day following the day on which public announcement is first made of the date of the annual meeting.

Under Section 1701.59(D) of the ORC, unless the articles or the regulations of a corporation state by specific reference that this provision of Ohio law does not apply, a director is liable for monetary damages for any action or omission as a director only if it is proven by clear and convincing evidence that this act or omission was undertaken either with deliberate intent to cause injury to the corporation or with reckless disregard for the best interests of the corporation. This provision, however, does not affect the liability of directors under Section 1701.95 of the ORC, which relates to:

Section 1701.59(D) applies to our board of directors because our Amended Articles of Incorporation and Amended Code of Regulations do not specifically exclude its applicability. This may have the effect of reducing the likelihood of derivative litigation against directors, and may discourage or deter shareholders or management from bringing a lawsuit against directors based on their actions or omissions, even though such a lawsuit, if successful, might otherwise have benefited us and our shareholders.

Holders of our common stock have no preemptive or conversion rights and are not subject to further calls or assessments by us. There are no redemption or sinking fund provisions applicable to our common stock.

Shares of our common stock are traded on the New York Stock Exchange under the ticker symbol “FE.”

The Transfer Agent and Registrar for our common stock is American Stock Transfer & Trust Company, LLC, P.O. Box 2016, New York, New York, 10272-2016.

Cash dividends, per share of our common stock, paid in 2016 through the date of this Prospectus include three quarterly payments of $0.36 per share. Cash dividends, per share of our common stock, paid in 2014 and 2015 include four quarterly payments of $0.36 per share. Cash dividends, per share of our common stock, paid in 2013 include four quarterly payments of $0.55 per share. Future dividends will depend on our future earnings and the ability of our regulated subsidiaries to pay cash dividends to us which, in the case of our regulated subsidiaries, may be subject to certain regulatory limitations and also subject to charter and indenture limitations for some of those subsidiaries that may, in general, restrict the amount of retained earnings available for these dividends. These limitations, however, do not currently materially restrict payment of these dividends.

Persons who acquire shares of our common stock through the Plan and resell them shortly after acquiring them, including coverage of short positions, under certain circumstances, may be participating in a distribution of securities that would require compliance with Regulation M under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act, and may be considered to be underwriters within the meaning of the Securities Act of 1933, as amended, which we refer to as the Securities Act. We will not extend to any such person any rights or privileges other than those to which it would be entitled as a participant, nor will we enter into any agreement with any such person regarding the resale or distribution by any such person of the shares of our common stock so purchased. We have no arrangements or understandings, formal or informal, with any person relating to the sale of shares of our common stock to be received under the Plan. We reserve the right to modify, suspend or terminate participation in the Plan by otherwise eligible persons in order to eliminate practices which are inconsistent with the purpose of the Plan.

The maximum amount of cash investments is $100,000 per calendar year, per participant.

Reinvested dividends and cash investments will be used to purchase shares of FirstEnergy common stock which, at the option of FirstEnergy, will be either newly issued or treasury shares purchased by AST from us or will be purchased on behalf of Plan participants in the open market or in privately negotiated transactions by AST through the Independent Agent. The determination of the source of shares of common stock to be used for purchases under the Plan will be made at the discretion of FirstEnergy. We may change the source of the shares of common stock to be used for purchases under the Plan at any time without notice to you. We will not change more than once in any three-month period the source of the purchase of the shares.

When shares to be purchased are satisfied by newly issued or treasury shares purchased by AST from us, the price will be the average of the high and low prices of FirstEnergy’s common stock, as reported in the New York Stock Exchange Composite Transactions for the investment date (or the next preceding day on which FirstEnergy common stock is traded on the New York Stock Exchange, if it is not traded on the investment date), plus a transaction fee not to exceed $0.09 per share.

When shares are purchased in the open market or in privately negotiated transactions, the purchase price per share will be the weighted average price of the aggregated shares purchased by AST during the purchase period plus a transaction fee not to exceed $0.09 per share.

For open market purchases, if shares cannot be purchased with respect to an investment date due to the inability to purchase shares during the purchase period, or if any purchase is deemed

to be otherwise inadvisable by AST, FirstEnergy and/or the Independent Agent, the dividends and cash investments which otherwise would have been invested will be paid or returned, as the case may be, by AST issuing checks to the affected participants without interest.

Participants’ requests to sell Plan shares will be aggregated and sold as often as daily but at least weekly, depending on the volume. The price of the shares sold will be the weighted average price of the aggregated shares sold by the Independent Agent or designated broker less a transaction fee not to exceed $0.09 per share. A check for sale of the shares, less the transaction fee, generally will be mailed to the participant three business days after the shares are sold.

As described above, participants will pay a transaction fee for each share purchased or sold to cover any applicable brokerage commissions and administrative costs of the Plan. This transaction fee is not to exceed $0.09 per share; however, there is currently no maximum amount set for the Plan’s fees. Plan participants will receive advance written notice if there is a need to charge a transaction fee of greater than $0.09 per share due to increased administrative costs or broker commissions.

Shares of our common stock may not be available under the Plan in all states. We are not making an offer to sell our common stock in any state where the offer or sale is not permitted.

The validity of the shares of common stock offered by this Prospectus will be passed upon for us by Robert P. Reffner, Esq., Vice President and General Counsel of FirstEnergy Service Company, a wholly-owned subsidiary of FirstEnergy. As of September 6, 2016, Mr. Reffner beneficially owned approximately 33,992 shares of our common stock and 39,289 shares of unvested stock awards, which include restricted stock, performance shares and restricted stock units.

Ohio Revised Code. Section 1701.13(E) of the Ohio Revised Code, or ORC, provides that an Ohio corporation may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that the person is or was a director, officer, employee or agent of that corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee, member, manager, or agent of another entity against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal matter, if the person had no reasonable cause to believe the person’s conduct was unlawful. In addition, no indemnification shall be made in respect of a claim against such person by or in the right of the corporation, if the person is adjudged to be liable for negligence or misconduct in the performance of the person’s duty to the corporation except to the extent provided in the court order. Indemnification may be made if ordered by a court or authorized in each specific case by the directors of the indemnifying corporation acting at a meeting at which, for the purpose, any director who is a party to or threatened with any such action, suit or proceeding may not be counted in determining the existence of a quorum and may not vote. If, because of the foregoing limitations, the directors are unable to act in this regard, such determination may be made by written opinion of independent legal counsel other than an attorney, or a firm having associated with it an attorney, who has been retained by or who has performed services for the corporation or any person to be indemnified during the five years preceding the date of determination. Alternatively, such determination may be made by the corporation’s shareholders.

Section 1701.13(E) of the ORC provides that the indemnification thereby permitted shall not be exclusive of any other rights that directors, officers or employees may have, including rights under insurance purchased by the corporation. Further, a right to indemnification or to advancement of expenses arising under a provision of the articles or the regulations of a corporation may not be eliminated or impaired by an amendment to that provision after the occurrence of the act or omission that becomes the subject of the civil, criminal, administrative, or investigative action, suit, or proceeding for which the indemnification or advancement of expenses is sought, unless the provision in effect at the time of that act or omission explicitly authorizes that elimination or impairment after the act or omission has occurred.

Amended Code of Regulations. Regulation 31 of FirstEnergy’s Amended Code of Regulations provides as follows:

“The Corporation shall indemnify, to the full extent then permitted by law, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a member of the Board of Directors or an officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The Corporation shall pay, to the full extent then required by law, expenses, including attorney’s fees, incurred by a member of the Board of Directors in defending any such action, suit or proceeding as they are incurred, in advance of the final disposition thereof, and may pay, in the same manner and to the full extent then permitted by law, such expenses incurred by any other person. The indemnification and payment of expenses provided hereby shall not be exclusive of, and shall be in addition to, any other rights granted to those seeking indemnification under any law, the Articles of Incorporation, any agreement, vote of shareholders or disinterested members of the Board of Directors, or otherwise, both as to action in official capacities and as to action in another capacity while he or she is a member of the Board of Directors, or an officer, employee or agent of the Corporation, and shall continue as to a person who has ceased to be a member of the Board of Directors, trustee, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.”

Regulation 32 of FirstEnergy’s Amended Code of Regulations provides as follows:

“The Corporation may, to the full extent then permitted by law and authorized by the Board of Directors, purchase and maintain insurance or furnish similar protection, including but not limited to trust funds, letters of credit or self-insurance, on behalf of or for any persons described in Regulation 31 against any liability asserted against and incurred by any such person in any such capacity, or arising out of his status as such, whether or not the Corporation would have the

power to indemnify such person against such liability. Insurance may be purchased from or maintained with a person in which the Corporation has a financial interest.”

Directors and Officers Liability Insurance. The Registrant maintains and pays the premium on contracts insuring it (with certain exclusions) against any liability to directors and officers it may incur under the above indemnity provisions and insuring each of its directors and officers (with certain exclusions) against liability and expense, including legal fees, which he or she may incur by reason of his or her relationship to it.

Indemnification Agreements. The Registrant has entered into indemnification agreements with its directors and officers, the forms of which are incorporated by reference to Exhibits 10.1 and 10.2 of FirstEnergy’s Form 10-Q for the quarter ended March 31, 2009, and Exhibit 10.1 of FirstEnergy’s Form 8-K filed July 23, 2012. Each indemnification agreement provides, among other things, that the Registrant will, subject to the agreement terms, indemnify a director or officer, as applicable, if, by reason of the individual’s status as a director or officer, the person incurs losses, liabilities, judgments, fines, penalties, or amounts paid in settlement in connection with any threatened, pending, or completed proceeding, whether of a civil, criminal, administrative, or investigative nature. In addition, each indemnification agreement provides for the advancement of expenses incurred by a director or officer, as applicable, subject to certain exceptions, in connection with proceedings covered by the indemnification agreement. As a director and officer of the Registrant, Charles E. Jones has agreements that address indemnity in both roles.

The following exhibits are incorporated by reference into this registration statement or are filed herewith and made a part hereof:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of the securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Akron, State of Ohio, on the 14^th day of September, 2016.

Each of the undersigned directors and officers of the Registrant, individually as such director and/or officer, hereby makes, constitutes and appoints Charles E. Jones, James F. Pearson, Leila L. Vespoli, Ketan K. Patel and Lucas F. Torres and each of them, singly or jointly, with full power of substitution, as his true and lawful attorney-in-fact and agent to execute in his name, place and stead, in any and all capacities, and to file with the Commission, this Registration Statement and any and all amendments, including post-effective amendments, to this Registration Statement, which amendment may make such changes in the Registration Statement as the Registrant deems appropriate hereby ratifying and confirming all that each of said attorneys-in-fact, or his, her or their substitute or substitutes, may do or cause to be done by virtue hereof.

Pursuant to the requirements of the Securities Act of 1933, this Registration Statement has been signed below by the following persons in the capacities and on the dates indicated.
