TABLE OF CONTENTS

We are responsible for the information contained and incorporated by reference in this prospectus, in any accompanying prospectus supplement, and in any related free writing prospectus we prepare or authorize. We have not authorized anyone to give you any other information, and we take no responsibility for any other information that others may give you. If you are in a jurisdiction where offers to sell, or solicitations of offers to purchase, the securities offered by this document are unlawful, or if you are a person to whom it is unlawful to direct these types of activities, then the offer presented in this document does not extend to you. The information contained in this document speaks only as of the date of this document, unless the information specifically indicates that another date applies.

ABOUT THIS PROSPECTUS

This prospectus is a part of a registration statement that we filed with the Securities and Exchange Commission, or the SEC, utilizing an automatic shelf registration process. We may use this prospectus to offer and sell from time to time any one or a combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will describe in an accompanying prospectus supplement the type, amount or number and other terms and conditions of the securities being offered, the price at which the securities are being offered, and the plan of distribution for the securities. The specific terms of the offered securities may vary from the general terms of the securities described in this prospectus, and accordingly the description of the securities contained in this prospectus is subject to, and qualified by reference to, the specific terms of the offered securities contained in the accompanied prospectus supplement. Our business, financial condition, results of operations and prospects may have changed since that date.

The prospectus supplement may also add, update or change information contained in this prospectus, including information about us. You should assume that the information contained or incorporated by reference in this prospectus or any prospectus supplement is accurate only as of the date on the front cover of the applicable document. Therefore, for a complete understanding of the offered securities, you should read both this prospectus and any prospectus supplement together with the additional information described under the heading “Where You Can Find More Information.”

For more detailed information about the securities, you can also read the exhibits to the registration statement. Those exhibits have been either filed with the registration statement or incorporated by reference to earlier SEC filings listed in the registration statement.

In this prospectus, unless the context indicates otherwise, the words “FirstEnergy,” “the company,” “we,” “our,” “ours” and “us” refer to FirstEnergy Corp. and its consolidated subsidiaries.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the information incorporated by reference herein include forward-looking statements based on information currently available to management. Such statements are subject to certain risks and uncertainties. These statements include declarations

1

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 Corp.’s common stock, and thereby on FirstEnergy Corp.’s preferred stock, during any period may in the aggregate vary from prior periods due to circumstances considered by FirstEnergy Corp.’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.

These forward-looking statements are also qualified by, and should be read in conjunction with the other cautionary statements and risks that are included in our 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. These risks, unless otherwise indicated, are presented on a consolidated basis for FirstEnergy; if and to the extent a deconsolidation occurs with respect to certain FirstEnergy companies, the risks described herein may materially change. The foregoing review of factors also should not be construed as exhaustive. New factors emerge from time to

5

time, and it is not possible for management to predict all such factors, nor assess the impact of any such factor on our 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. We expressly disclaim any current intention to update, except as required by law, any forward-looking statements contained herein or in the information incorporated by reference as a result of new information, future events or otherwise.

THE COMPANY

We are an Ohio corporation, and our principal executive offices are located at 76 South Main Street, Akron, Ohio 44308. Our telephone number is (800) 736-3402 and our Internet website is www.firstenergycorp.com. Information contained on our website shall not be incorporated into, or be a part of, this prospectus.

RISK FACTORS

Investing in our securities involves risks. Before purchasing any securities offered, you should carefully consider the risk factors that are incorporated by reference herein from the section captioned “Risk Factors” in our most recent Annual Report on Form 10-K, together with all of the other information included in this prospectus and any prospectus supplement and any other information that we have incorporated by reference, including annual, quarterly and other reports filed with the SEC subsequent to the date hereof. Any of these risks, as well as other risks and uncertainties, could harm or otherwise impact our financial condition, results of operations or cash flows. See also “Cautionary Note Regarding Forward-Looking Statements” in this prospectus.

USE OF PROCEEDS

We intend to use the net proceeds we receive from issuance of the securities offered under this prospectus for general corporate purposes, unless otherwise specified in the prospectus supplement relating to a specific issue of securities. General corporate purposes may include, but are not limited to, financing and operating activities, capital expenditures, acquisitions, maintenance of our assets and refinancing our existing indebtedness. Until we apply the proceeds from a sale of securities to the intended purposes, we may invest those proceeds.

Unless the applicable prospectus supplement indicates otherwise, we will not receive any proceeds from the sale of securities by selling security holders.

RATIO OF EARNINGS TO FIXED CHARGES

The following table contains our consolidated ratio of earnings to fixed charges for the periods indicated. You should read these ratios in connection with our consolidated financial statements, including the notes to those statements, incorporated by reference in this prospectus. We have not presented a ratio of earnings to combined fixed charges and preferred stock dividends because we did not have preferred stock outstanding during any such periods. Therefore, our ratio of earnings to combined fixed charges and preferred dividends for any given period is equivalent to our ratio of earnings to fixed charges.

DESCRIPTION OF COMMON STOCK AND PREFERRED STOCK

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 may not contain all of the information that may be important to you, 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 700,000,000 shares of common stock, par value $0.10 per share. The common stock outstanding 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 1,616,000 shares have been designated Series A Convertible Preferred Stock.

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. We will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the amendment to our Amended Articles of Incorporation establishing the terms of the preferred stock with the SEC. On January 22, 2018, we issued shares of our Series A Convertible Preferred Stock and amended our Amended Articles of Incorporation to designate the terms of the Series A Convertible Preferred Stock.

Dividend Rights

Subject only to any prior rights and preferences of any shares of our preferred stock that are or 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. Our Series A Convertible Preferred Stock participates in declared dividends on the common stock on an as-converted basis based on the number of shares of common stock a holder

8

of Series A Convertible Preferred Stock would receive if its shares of Series A Convertible Preferred Stock were converted on the dividend record date at the Conversion Price (as defined in our Amended Articles of Incorporation) in effect at that time. Such dividends will be paid at the same time that the dividends on common stock are paid.

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. Future dividends will depend on our future earnings and the ability of our regulated subsidiaries to pay cash dividends to us, which are subject to certain regulatory limitations and also subject to charter and contractual 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.

Liquidation Rights

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. Shares of our Series A Convertible Preferred Stock will automatically convert into shares of common stock immediately prior to a bankruptcy or liquidation in accordance with the terms of the Amended Articles of Incorporation.

Voting Rights

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 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:

9

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.

The holders of our Series A Convertible Preferred Stock have limited class voting rights related to the creation of additional securities that are senior or pari passu with the Series A Convertible Preferred Stock, as well as certain reclassifications and amendments that would affect the rights of the holders of Series A Convertible Preferred Stock. The holders of Series A Convertible Preferred Stock also have the right to approve issuances of securities convertible or exchangeable for common stock, subject to certain exceptions for compensation arrangements and bona fide dividend reinvestment or share purchase plans.

Ohio Law Anti-takeover Provisions

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

10

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 may not contain all the information that is important to you 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 33 1/3%; at least 33 1/3% 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.

11

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.

Anti-takeover Effects

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.

12

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.

Limitation on Directors’ Liability

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.

13

Preemptive or Conversion Rights

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.

Each share of our Series A Convertible Preferred Stock will be convertible into a number of shares of common stock equal to a $1,000 liquidation preference, divided by the Conversion Price then in effect. As of March 5, 2018, the Conversion Price in effect was $27.42 per share. The Conversion Price is subject to anti-dilution adjustments and adjustments for subdivisions and combinations of the common stock, as well as dividends on the common stock paid in common stock and for certain equity issuances below the Conversion Price then in effect. The Series A Convertible Preferred Stock will generally be convertible at the option of holders beginning on July 22, 2018. The holders of Series A Convertible Preferred Stock may also elect to convert their shares if the Company undergoes a Fundamental Change (as defined in our Amended Articles of Incorporation). Furthermore, the Series A Convertible Preferred Stock will automatically convert to common stock upon certain events of bankruptcy or liquidation of the Company. The Company may elect to convert the Series A Convertible Preferred Stock if, at any time, fewer than 323,200 shares of Series A Convertible Preferred Stock are outstanding.

In general, any shares of Series A Convertible Preferred Stock outstanding on July 22, 2019 will be automatically converted. However, no shares of Series A Convertible Preferred Stock will be converted (by the holder thereof or otherwise) prior to January 22, 2020 if such conversion will cause a converting holder to be deemed to beneficially own (for purposes of Rule 13d-3 under the Securities Exchange Act of 1934 (the “Exchange Act”)), together with its affiliates whose holdings would be aggregated with such holder for purposes of Section 13(d) under the Exchange Act, more than 4.9% of the then-outstanding common stock. Furthermore, in no event shall the Company issue more than 58,964,222 shares of common stock (the “Share Cap”) in the aggregate upon conversion of the Series A Convertible Preferred Stock. From and after the time at which the aggregate number of shares of common stock issued upon conversion of the Series A Convertible Preferred Stock equals the Share Cap, each holder electing to convert shares of Series A Convertible Preferred Stock will be entitled to receive a cash payment equal to the market value of the common stock such holder does not receive upon conversion.

DESCRIPTION OF DEBT SECURITIES

The debt securities that we may offer from time to time by this prospectus will be our senior unsecured debt securities and will rank equally with all of our other unsecured and unsubordinated debt (in this “Description of Debt Securities” section, unless the context indicates otherwise, the words “FirstEnergy,” “the company,” “we,” “our,” “ours” and “us” refer to FirstEnergy Corp. and not its consolidated subsidiaries). The debt securities will be issued under an indenture, dated as of November 15, 2001, between us and The Bank of New York Mellon Trust Company, N.A., as successor trustee. The indenture gives us broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which such particular terms modify the terms of the indenture or otherwise vary from the terms and provisions set forth below will be described in the prospectus supplement relating to those debt securities.

The indenture contains the full text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the debt securities or the indenture. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of terms used in the indenture. You should read the indenture incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. We also include references in parentheses to certain sections of the indenture. Whenever we refer to particular sections or defined terms of the indenture in this prospectus or in a prospectus supplement, these sections or defined terms are incorporated by reference herein or in the prospectus supplement. This summary also is subject to and qualified by reference to the description of the particular terms of the debt securities described in the applicable prospectus supplement or supplements.

If applicable, the prospectus supplement relating to an issue of debt securities will describe any material United States federal income tax considerations relevant to those debt securities.

There is no requirement under the indenture that future issues of our debt securities be issued under the indenture. We will be free to use other indentures or documentation, containing provisions different from those included in the indenture or applicable to one or more issues of debt securities, in connection with future issues of other debt securities.

General

The indenture does not limit the aggregate principal amount of debt securities that we may issue under the indenture. The indenture provides that the debt securities may be issued in one or

16

more series and may be convertible or exchangeable. The debt securities may be issued at various times and may have differing maturity dates and may bear interest at differing rates. We need not issue all debt securities of one series at the same time and, unless otherwise provided, we may reopen a series, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series. Any convertible debt securities that we may issue will be convertible into or exchangeable for common stock or other securities of ours or of a third party. Conversion may be mandatory or at your option and would be at prescribed conversion rates.

Prior to the issuance of each series of debt securities, the terms of the particular securities will be specified in a supplemental indenture, a board resolution or in one or more officer’s certificates authorized pursuant to a board resolution. We refer you to the applicable prospectus supplement for a description of the following terms of the series of debt securities:

17

Unless we otherwise indicate in the applicable prospectus supplement, the debt securities will be denominated in United States currency in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Unless we otherwise indicate in the applicable prospectus supplement, there are no provisions in the indenture or the debt securities that require us to redeem, or permit the holders to cause a redemption of, the debt securities or that otherwise protect the holders in the event that we incur substantial additional indebtedness, whether or not in connection with a change in control of our company.

Security and Ranking

The debt securities will be our senior unsecured debt securities and will rank equally with all of our other unsecured and unsubordinated debt.

We conduct our operations primarily through our consolidated subsidiaries and substantially all of our consolidated assets are held by our subsidiaries.

Accordingly, our cash flow and our ability to meet our obligations under the debt securities are largely dependent upon the earnings of our consolidated subsidiaries and the distribution or other payment of these earnings to us in the form of dividends. Our consolidated subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on our debt securities or to make any funds available for payment of amounts due on our debt securities.

Because we are a holding company, our obligations under the debt securities will be effectively subordinated to all existing and future liabilities of our consolidated subsidiaries.

18

Therefore, our rights and the rights of our creditors, including the rights of the holders of our debt securities, to participate in the liquidation of assets of any subsidiary will be subject to the prior claims of the subsidiary’s creditors. To the extent that we may be a creditor with recognized claims against any of our subsidiaries, our claims would still be effectively subordinated to any security interest in, or mortgages or other liens on, the assets of the subsidiary and would be subordinated to any indebtedness, other liabilities, and preferred securities, of the subsidiary, senior to that held by us.

Payment and Paying Agents

Unless otherwise indicated in a prospectus supplement, we will pay interest on our debt securities on each interest payment date by wire transfer to an account at a banking institution in the United States that is designated in writing to the trustee by the person entitled to that payment or by check mailed to the person in whose name the debt security is registered as of the close of business on the regular record date relating to the interest payment date, except that interest payable at stated maturity, upon redemption or otherwise, will be paid to the person to whom principal is paid. However, if we default in paying interest on a debt security, we may pay defaulted interest to the registered owner of the debt security as of the close of business on a special record date selected by the trustee, which will be between 10 and 15 days before the date we propose for payment of the defaulted interest, or in any other lawful manner of payment that is consistent with the requirements of any securities exchange on which the debt securities may be listed for trading, if the trustee finds it practicable (See Section 307).

Redemption

We will set forth any terms for the redemption of debt securities in a prospectus supplement. Unless we indicate differently in a prospectus supplement, and except with respect to debt securities redeemable at the option of the registered holder, debt securities will be redeemable upon notice by mail between 30 and 60 days prior to the redemption date. If less than all of the debt securities of any series or any tranche of a series are to be redeemed, the trustee will select the debt securities to be redeemed and will choose the method of random selection it deems fair and appropriate. (See Sections 301, 403 and 404.)

Debt securities will cease to bear interest on the redemption date. We will pay the redemption price and any accrued interest to the redemption date once you surrender the debt security for redemption. (See Section 405.) If only part of a debt security is redeemed, the trustee will deliver to you a new debt security of the same series for the remaining portion without charge. (See Section 406.)

19

We may make any redemption conditional upon the receipt by the paying agent, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the paying agent has not received the money by the date fixed for redemption, we will not be required to redeem the debt securities. (See Section 404.)

The debt securities will be issued without interest coupons and in denominations that are even multiples of $1,000, unless otherwise indicated in the applicable prospectus supplement. Debt securities of any series will be exchangeable for other debt securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor, unless otherwise indicated in the applicable prospectus supplement. (See Section 305.)

Unless we otherwise indicate in the applicable prospectus supplement, debt securities may be presented for registration of transfer, duly endorsed or accompanied by a duly executed written instrument of transfer, at the office or agency maintained for this purpose, without service charge except for reimbursement of taxes and other governmental charges as described in the indenture. (See Section 305.)

In the event of any redemption of debt securities of any series, the trustee will not be required to exchange or register a transfer of any debt securities of the series selected, called or being called for redemption except the unredeemed portion of any debt security being redeemed in part. (See Section 305.)

Limitation on Liens

The indenture provides that, except as otherwise specified with respect to a particular series of debt securities, we will not pledge, mortgage, hypothecate or grant a security interest in, or permit any mortgage, pledge, 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 equally and ratably securing the outstanding debt securities of that series and all other indebtedness entitled to be so secured. (See Section 608.)

This restriction does not apply to, or prevent the creation or any extension, renewal or refunding of:

20

Unless we otherwise specify in the prospectus supplement for a particular series of debt securities, we may, without securing the debt securities of that series, pledge, mortgage, hypothecate or grant a security interest in, or permit any mortgage, pledge, security interest or other lien, in addition to liens expressly permitted as described in the preceding paragraphs, upon, capital stock of any subsidiary now or hereafter owned by us to secure any indebtedness, which would otherwise be subject to the foregoing restriction, in an aggregate amount which, together with all other such indebtedness, does not exceed 10% of our consolidated net tangible assets. (See Section 608.)

For purposes of this covenant, “consolidated net tangible assets” means the amount shown as total assets on our consolidated balance sheet, less (i) intangible assets including, without limitation, such items as goodwill, trademarks, trade names, patents, and unamortized debt expense; (ii) current liabilities; and (iii) appropriate adjustments, if any, related to minority interests. These amounts will be determined in accordance with accounting principles generally accepted in the United States.

The foregoing limitation does not limit in any manner:

21

Consolidation, Merger, Conveyance, Sale or Transfer

We have agreed not to consolidate with or merge into any other entity or convey, sell or otherwise transfer our properties and assets substantially as an entirety to any entity unless:

Modification of the Indenture

Under the indenture or any supplemental indenture, our rights and the rights of the holders of debt securities may be changed with the consent of the holders representing a majority in principal amount of the outstanding debt securities of all series affected by the change, voting as one class, provided that the following changes may not be made without the consent of the holders of each outstanding debt security affected thereby:

22

An “original issue discount security” means any security authenticated and delivered under the indenture which provides for an amount less than the principal amount thereof to be due and payable upon the declaration of acceleration of the maturity thereof.

The indenture also permits us and the trustee to amend the indenture without the consent of the holders of any debt securities for any of the following purposes:

23

Events of Default

An event of default with respect to any series of debt securities is defined in the indenture as being any one of the following:

An event of default regarding a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities.

We will be required to file with the trustee annually an officer’s certificate as to the absence of default in performance of all covenants in the indenture. (See Section 606.) The indenture provides that the trustee may withhold notice to the holders of the debt securities of any default, except in payment of principal of, or premium, if any, or interest on, the debt securities or in the

24

payment of any sinking fund installment with respect to the debt securities, if the trustee in good faith determines that it is in the interest of the holders of the debt securities to do so. (See Section 902.)

The indenture provides that, if an event of default with respect to the debt securities of any series occurs and continues, either the trustee or the holders of 33% or more in aggregate principal amount of the debt securities of that series may declare the principal amount of all the debt securities to be due and payable immediately. However, if the event of default is applicable to all outstanding debt securities under the indenture, only the trustee or holders of at least 33% in principal amount of all outstanding debt securities of all series, voting as one class, and not the holders of any one series, may make such a declaration of acceleration.

At any time after a declaration of acceleration with respect to the debt securities of any series has been made and before a judgment or decree for payment of the money due has been obtained, the event of default giving rise to such declaration of acceleration will be considered waived, and such declaration and its consequences will be considered rescinded and annulled, if:

There is no automatic acceleration, even in the event of our bankruptcy, insolvency or reorganization. (See Section 802.)

Subject to the provisions of the indenture relating to the duties of the trustee, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of the debt securities, unless the holders shall have offered to the trustee reasonable indemnity. (See Section 903.)

Subject to the provision for indemnification, the holders of a majority in principal amount of the debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or

25

power conferred on the trustee with respect to the debt securities of that series. However, if the event of default relates to more than one series of debt securities, only the holders of a majority in aggregate principal amount of all affected series will have the right to give this direction. However, the trustee shall have the right to decline to follow any direction if the trustee shall determine that the action so directed conflicts with any law or the provisions of the indenture or if the trustee shall determine that the action would be prejudicial to holders not taking part in the direction. (See Section 812.)

Satisfaction and Discharge

We will be discharged from our obligations on the debt securities of any series, or any portion of the principal amount of the debt securities of any series, if we:

For this purpose, “eligible obligations” include direct obligations of, or obligations unconditionally guaranteed by, the United States entitled to the benefit of the full faith and credit thereof and certificates, depositary receipts or other instruments which evidence a direct

26

ownership interest in such obligations or in any specific interest or principal payments due in respect thereof and which do not contain provisions permitting their redemption or other prepayment at the option of the issuer thereof.

In the event that all of the conditions set forth above have been satisfied for any series of debt securities, or portions thereof, except that, for any reason, we have not delivered the officer’s certificate and opinion described under the second bulleted item above, the holders of those debt securities will no longer be entitled to the benefits of certain of our covenants under the indenture, including the covenant described above in “— Limitation on Liens.” Our indebtedness under those debt securities, however, will not be deemed to have been satisfied and discharged prior to maturity, and the holders of those debt securities may continue to look to us for payment of the indebtedness represented by those debt securities. (See Section 701.)

The indenture will be deemed satisfied and discharged when no debt securities remain outstanding and when we have paid all other sums payable by us under the indenture. (See Section 702.) All moneys we pay to the trustee or any paying agent on debt securities which remain unclaimed at the end of two years after payments have become due will be paid to us or upon our order. Thereafter, the holder of those debt securities may look only to us for payment and not the trustee or any paying agent. (See Section 603.)

Resignation or Removal of Trustee

The trustee may resign at any time by giving written notice to us specifying the day upon which the resignation is to take effect. The resignation will take effect immediately upon the later of the appointment of a successor trustee and the specified day. (See Section 910.)

The trustee may be removed at any time by an instrument or concurrent instruments in writing delivered to the trustee and us and signed by the holders, or their attorneys-in-fact, representing at least a majority in principal amount of the then outstanding debt securities. In addition, under certain circumstances, we may remove the trustee upon notice to the holder of each debt security outstanding and the trustee, and appointment of a successor trustee. (See Section 910.)

Concerning the Trustee

The Bank of New York Mellon Trust Company, N.A. is the successor trustee under the indenture. We and our affiliates maintain other banking relationships in the ordinary course of business with the trustee and its affiliates.

27

Governing Law

The indenture and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the law of any other jurisdiction shall be mandatorily applicable.

28

DESCRIPTION OF WARRANTS

We may issue warrants to purchase our debt or equity securities, securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement for any offering of warrants will describe the following terms of the warrants:

29

We will file a copy of the warrant and warrant agreement with the SEC each time we issue a series of warrants, and these warrants and warrant agreements will be incorporated by reference into the registration statement of which this prospectus is a part. A holder of our warrants should refer to the provisions of the applicable warrant agreement and prospectus supplement for more specific information.

30

PLAN OF DISTRIBUTION

Initial Offering and Sale of Securities

We may sell securities through one or more underwriters or dealers, directly to one or more purchasers, in a rights offering, in “at-the-market” offerings, within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market or an exchange or otherwise, through agents, pursuant to forward contracts or through a combination of any of these sale methods, or through any other methods described in a prospectus supplement. The prospectus supplement relating to the securities being offered will set forth the terms of the offering and the method of distribution, including:

We may distribute the securities offered under this prospectus from time to time in one or more transactions at a fixed price or prices, which may be changed, at prevailing markets prices or at prices determined as the prospectus supplement specifies. We may sell securities through forward contracts or similar arrangements.

Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If we use underwriters for a sale of securities, we will enter into an underwriting agreement with the underwriters at the time of sale of those securities. Unless we inform you otherwise in a prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to certain conditions and the underwriters will be obligated to purchase all of the offered securities if any are purchased. The underwriters will acquire the securities for their own account. The underwriters may resell the securities in one or more transactions at a fixed public offering price, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

31

Only those underwriters identified in the prospectus supplement are deemed to be underwriters in connection with the securities offered in the prospectus supplement.

If we use dealers in a sale, unless we inform you otherwise in a prospectus supplement, we will sell the securities to the dealers as principals.

The dealers may then resell such securities to the public at varying prices that they determine at the time of resale.

We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents designated from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any sales of these securities in the prospectus supplement.

In connection with the sale of securities, underwriters, dealers or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and also may receive commissions from securities purchasers for whom they may act as agent.

Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent. Any underwriting or other compensation which we pay to underwriters or agents in connection with the securities offering, and any discounts, concessions or commissions which underwriters allow to dealers, will be set forth in the applicable prospectus supplement.

Underwriters, dealers and agents participating in the securities distribution may be deemed to be underwriters, and any discounts and commissions they receive and any profit they realize on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters, and their controlling persons, and agents may be entitled, under agreements we enter into with them, to indemnification against certain civil liabilities, including liabilities under the Securities Act. Some of the underwriters, dealers or agents and some of their affiliates who participate in the securities distribution may engage in other transactions with, and perform other services for, us and our subsidiaries or affiliates in the ordinary course of business.

32

In order to facilitate an offering of securities, persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the offered securities. Such transactions, if commenced, may be discontinued at any time. If any such activities will occur, they will be described in the applicable prospectus supplement.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement.

Sales by Selling Security Holders

Selling security holders may use this prospectus in connection with resales of securities they hold as described in the applicable prospectus supplement. The applicable prospectus supplement will identify the selling security holders, the terms of the securities and any material relationships we have with the selling security holders. Selling security holders may be deemed to be underwriters under the Securities Act in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act. Unless otherwise provided in a prospectus supplement, the selling security holders will receive all the proceeds from the sale of the securities.

33

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered under this prospectus will be passed upon for us by Jones Day. Additional legal matters may be passed on for us, or any underwriters, dealers or agents, by counsel we will name in the applicable prospectus supplement.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth the expenses (other than underwriting discounts and commissions) expected to be incurred in connection with the offerings described in this registration statement.

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

II-1

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 the registrant’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

II-2

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 the registrant’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 the registrant’s Form 10-Q for the quarter ended March 31, 2009, and Exhibit 10.1 of the registrant’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 an agreement that addresses indemnity in both roles.

II-4

The undersigned registrant hereby undertakes:

(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 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 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;

II-5

provided, however, that paragraphs (i), (ii) and (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 the 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.

II-6

(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 an 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 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.

(7) To supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

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 Securities and Exchange 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

II-7

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.

II-8
