ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a shelf registration process. Under this shelf process, we may periodically sell the securities described in this prospectus in one or more offerings in amounts, at prices and on terms that we determine at the time of the offering, with an aggregate initial offering price of up to $150,000,000. This prospectus provides a general description of our common stock, preferred stock, debt securities, depositary shares, warrants, purchase contracts and units that we may offer. Each time we offer securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information, including information about us, contained in this prospectus. You should read both this prospectus and any prospectus supplement together with any free writing prospectus and any additional information described under the heading “Where You Can Find More Information.”

You should rely only on the information contained or incorporated by reference in this prospectus and in any prospectus supplement or in any free writing prospectus that we may provide you. We have not authorized anyone to provide you with different information. You should not assume that the information contained in this prospectus, any prospectus supplement, any document incorporated by reference or any free writing prospectus is accurate as of any date, other than the date mentioned on the cover page of such document. We are not making offers to sell the securities in any jurisdiction in which an offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to anyone to whom it is unlawful to make an offer or solicitation.

Unless the context suggests otherwise, references in this prospectus to “GrafTech,” the “Company,” “we,” “us,” and “our” refer to GrafTech International Ltd., a Delaware corporation, and its consolidated subsidiaries. See “GrafTech International Ltd.” below for more information. All dollar amounts in this prospectus are in U.S. dollars and are expressed in thousands unless specified otherwise. The financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”).

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the documents incorporated by reference, contains, and any prospectus supplement may contain, forward-looking statements within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements reflect our current views with respect to, among other things, financial projections, plans and objectives of management for future operations, future economic performance and short-term and long-term liquidity. Examples of forward-looking statements include, among others, statements we make regarding future estimated volume, pricing and revenue, and anticipated levels of capital expenditures and cost of goods sold. You can identify these forward-looking statements by the use of forward-looking words such as “will,” “may,” “plan,” “estimate,” “project,” “believe,” “anticipate,” “expect,” “foresee,” “intend,” “should,” “would,” “could,” “target,” “goal,” “continue to,” “positioned to,” “are confident,” or the negative versions of those words or other comparable words. Any forward-looking statements contained in this prospectus, any prospectus supplement and the documents incorporated by reference are based upon our historical performance and on our current plans, estimates and expectations considering information currently available to us. The inclusion of this forward-looking information should not be regarded as a representation by us that the future plans, estimates, or expectations contemplated by us will be achieved. Our expectations and targets are not predictions of actual performance and historically our performance has deviated, often significantly, from our expectations and targets. These forward-looking statements are subject to various risks and uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. Accordingly, there are or will be

important factors that could cause our actual results to differ materially from those indicated in these statements. We believe that these factors include, but are not limited to:

•

our dependence on the global steel industry generally and the electric arc furnace (“EAF”) steel industry in particular;

•

the cyclical nature of our business and the selling prices of our products, which may remain at depressed levels or further decline in the future, and may continue to experience prolonged periods of reduced profitability and net losses or adversely impact liquidity;

•

the sensitivity of our business and operating results to economic conditions, including any recession, and the possibility others may not be able to fulfill their obligations to us in a timely fashion or at all;

•

the possibility that we may be unable to implement our business strategies in an effective manner, including our ability to effectively increase or maintain existing prices and shift sales to regions with higher average selling prices;

•

continued overcapacity of the global graphite electrode industry, which may further adversely affect graphite electrode prices;

•

the competitiveness of the graphite electrode industry;

•

our dependence on the cost and availability of manufacturing inputs, including raw materials, such as decant oil, petroleum needle coke, energy and freight, and disruptions in availability for such inputs;

•

our primary reliance on one facility in Monterrey, Mexico for the manufacturing of connecting pins;

•

the cost of electric power and natural gas, particularly in Europe;

•

our manufacturing operations are subject to hazards;

•

the legal, compliance, economic, social and political risks associated with our substantial operations in multiple countries;

•

the possibility that fluctuation of foreign currency exchange rates could materially harm our financial results;

•

the possibility that our results of operations could further deteriorate if our manufacturing operations were substantially disrupted for an extended period, including as a result of equipment failure, climate change, regulatory issues, natural disasters, public health crises, such as a global pandemic, political crises or other catastrophic events;

•

the risks and uncertainties associated with litigation, arbitration, and like disputes, including disputes related to contractual commitments;

•

our dependence on third parties for certain construction, maintenance, engineering, transportation, warehousing and logistics services;

•

the possibility that we are subject to information technology systems failures, cybersecurity incidents, network disruptions and breaches of data security, including with respect to our third-party suppliers and business partners;

•

the possibility that we are unable to recruit or retain key management and plant operating personnel or successfully negotiate with the representatives of our employees, including labor unions;

•

the sensitivity of long-lived assets on our balance sheet to changes in the market;

•

our dependence on protecting our intellectual property and the possibility that third parties may claim that our products or processes infringe their intellectual property rights;

•

the impact of inflation and our ability to mitigate the effect on our costs;

•

the impact of macroeconomic and geopolitical events on our business, results of operations, financial condition and cash flows, and the disruptions and inefficiencies in our supply chain that may occur as a result of such events;

•

uncertain shifts in domestic and foreign trade policies and the possibility that the imposition of current, new or increased custom duties and tariffs and trade barriers in the countries in which we, our customers and our suppliers operate could adversely affect our ability to compete, operations, results of operations and financial condition;

•

risks associated with strategic transactions, including acquisitions, divestitures, joint ventures, equity investments, and debt issuances, that could adversely affect our business, operating results and financial condition;

•

the possibility that our indebtedness could limit our financial and operating activities or that our cash flows may not be sufficient to service our indebtedness;

•

any current or future borrowings may subject us to interest rate risk;

•

risks and uncertainties associated with our ability to access the capital and credit markets could adversely affect our results of operations, cash flows and financial condition;

•

the possibility that disruptions in the capital and credit markets could adversely affect our customers and suppliers;

•

the possibility that restrictive covenants in our financing agreements could restrict or limit our operations; and

•

changes in health, safety and environmental regulations applicable to our manufacturing operations and facilities.

These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in the “Risk Factors” section of this prospectus, any prospectus supplement and the documents incorporated by reference. The forward-looking statements made in this prospectus relate only to events as of the date on which the statements are made. Except as required by law, we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this prospectus and any prospectus supplement that could cause actual results to differ before making an investment decision to purchase our securities. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

MARKET AND INDUSTRY DATA AND FORECASTS

Certain market and industry data included in this prospectus and the documents incorporated by reference herein have been obtained from third-party sources that we believe to be reliable. Market estimates are calculated by using independent industry publications, government publications and third-party forecasts in conjunction with our assumptions about our markets. We cannot guarantee the accuracy or completeness of this market and market share data and have not independently verified it. None of the sources has consented to the disclosure or use of data in this prospectus. While we are not aware of any misstatements regarding any market, industry or similar data presented herein or in the documents incorporated by reference herein, such data involves risks and

uncertainties and is subject to change based on various factors, including those discussed under the headings “Special Note Regarding Forward-Looking Statements” and “Risk Factors” in this prospectus and the documents incorporated by reference herein.

GRAFTECH INTERNATIONAL LTD.

GrafTech International Ltd., founded in 1886 and incorporated in Delaware, is a leading manufacturer of high-quality graphite electrode products essential to the production of EAF steel and other ferrous and non-ferrous metals. We believe that we have a competitive portfolio of low-cost ultra-high power (“UHP”) graphite electrode manufacturing facilities, with some of the highest capacity facilities in the world. We have graphite electrode manufacturing facilities in Calais, France; Pamplona, Spain; Monterrey, Mexico and St. Marys, Pennsylvania (idled in 2024). We are the only large-scale graphite electrode producer that is substantially vertically integrated into petroleum needle coke, our key raw material for graphite electrode manufacturing. This unique position provides us with a number of competitive advantages.

Our only reportable segment, Industrial Materials, is comprised of two major product categories: graphite electrodes and petroleum needle coke products. Our vision is to provide highly engineered graphite electrode products, services and solutions to EAF operators. Based on the high quality of our graphite electrodes, reliability of our petroleum needle coke supply and our excellent customer service, we believe that we are viewed as a preferred supplier to the global EAF steel producer market.

Our principal executive offices are located at 982 Keynote Circle, Brooklyn Heights, Ohio 44131 and our telephone number is (216) 676-2000. Our website address is www.graftech.com. Information on, or accessible through, our website is not part of this prospectus. We have included our website address only as an inactive textual reference and do not intend it to be an active link to our website.

RISK FACTORS

Investing in our securities involves risks. Before deciding to invest in our securities, you should carefully consider the discussion of risks and uncertainties under the heading “Risk Factors” contained in any applicable prospectus supplement and in the documents that are incorporated by reference in this prospectus. See the section entitled “Where You Can Find More Information.”

USE OF PROCEEDS

Except as otherwise set forth in a prospectus supplement, we intend to use the net proceeds from any sale of the securities described in this prospectus for our general corporate purposes, which may include financing our operating activities, refinancing our indebtedness, capital expenditures, repurchasing our common stock or other strategic opportunities. The net proceeds may be invested temporarily in short-term marketable securities or applied to repay short-term debt until they are used for their stated purpose.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the common stock, preferred stock, debt securities, depositary shares, warrants, purchase contracts and units that we may sell from time to time. These summary descriptions are not meant to be complete descriptions of each security. The particular terms of any security will be described in a related prospectus supplement, if necessary.

DESCRIPTION OF COMMON STOCK

The following descriptions are summaries of the material terms of our Amended and Restated Certificate of Incorporation, as amended (“Amended Certificate of Incorporation”), and Amended and Restated By-Laws (“Amended By-Laws”). These descriptions contain all information which we consider to be material, but may not contain all of the information that is important to you. To understand them fully, you should read our Amended Certificate of Incorporation and Amended By-Laws, copies of which are filed with the SEC as exhibits to the registration statement of which this prospectus is a part. The summary below is qualified in its entirety by reference to our Amended Certificate of Incorporation and Amended By-Laws. The terms of these securities may also be affected by the General Corporation Law of the State of Delaware (“DGCL”).

We may periodically issue shares of our common stock or other securities that can be exercised, converted or exchanged into shares of our common stock. The description below summarizes the general terms of our common stock. This section is a summary, and it does not describe every aspect of our common stock. This summary is subject to, and qualified in its entirety by, reference to the provisions of our Amended Certificate of Incorporation and our Amended By-Laws.

Authorized Capitalization

Our authorized capitalization consists of 300,000,000 authorized shares of common stock, par value $0.01 per share, and 30,000,000 shares of preferred stock, par value $0.01 per share.

Common Stock

The holders of our common stock are entitled to such dividends as our board of directors may declare from time to time from legally available funds subject to the preferential rights of the holders of any shares of our preferred stock that we may issue in the future. The holders of our common stock are entitled to one vote per share on any matter to be voted upon by stockholders, subject to the restrictions described below under the caption “Anti-Takeover Effects of Provisions of Our Certificate of Incorporation, Our By-Laws and Delaware Law.”

Our Amended Certificate of Incorporation does not provide for cumulative voting in connection with the election of directors. Accordingly, directors will be elected by a majority of the shares voting, or in the case of a contested election, a plurality of the shares voting, once a quorum is present. No holder of our common stock has any preemptive rights, conversion rights or other subscription rights, and there are no redemption or sinking fund provisions applicable to our common stock.

Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of our common stock are entitled to share, on a pro rata basis, all assets remaining after payment to creditors and subject to prior distribution rights of any shares of preferred stock that we may issue in the future. All of the outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

No shares of our preferred stock are currently outstanding. Our Amended Certificate of Incorporation authorizes our board of directors, without further action by our stockholders, to issue shares of preferred stock in one or more classes or series. The board may fix or alter the rights, preferences and privileges of the preferred stock, along with any limitations or restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each class or series of preferred stock. The preferred stock could have voting or conversion rights that could adversely affect the voting power or other rights of holders of our common stock. The issuance of preferred stock could also have the effect, under certain circumstances, of

delaying, deferring or preventing a change of control of our Company. See “Description of Preferred Stock” for more information about our preferred stock.

Anti-Takeover Effects of Provisions of our Certificate of Incorporation, our By-Laws and Delaware law

Our Amended Certificate of Incorporation and Amended By-Laws contain a number of provisions relating to corporate governance and to the rights of stockholders. Certain of these provisions may be deemed to have a potential “anti-takeover” effect in that such provisions may delay, defer or prevent a change of control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by the stockholders. These provisions include:

Classified Board of Directors

Our Amended Certificate of Incorporation provides that our board of directors is divided into three classes of directors, with the classes as nearly equal in number as possible, and with the directors serving three-year terms. As a result, approximately one-third of our board of directors will be elected each year. The Amended Certificate of Incorporation provides that the classification of the board of directors and the other provisions of the Amended Certificate of Incorporation may be amended by the affirmative vote of the holders of 66 2/3% of the voting power of our outstanding common stock. The classification of directors has the effect of making it more difficult for stockholders to change the composition of our board of directors. Our Amended Certificate of Incorporation and Amended By-Laws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors are fixed from time to time exclusively pursuant to a resolution adopted by the board of directors. Our board of directors currently has six members.

Removal of Directors; Vacancies

Our Amended Certificate of Incorporation provides that directors may be removed only for cause and then only by the affirmative vote of the holders of 66 2/3% or more of the voting power of our outstanding common stock.

Furthermore, any vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of our board of directors, may only be filled by the affirmative vote of a majority of our directors then in office even if less than a quorum. These provisions may deter a stockholder from removing incumbent directors and simultaneously gaining control of the board of directors by filling the vacancies created by such removal with its own nominees.

Business Combinations

We have opted out of Section 203 of the DGCL, which regulates corporate takeovers; however, our Amended Certificate of Incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless:

•

the business combination or the transaction which resulted in the stockholder becoming an interested stockholder was approved by the board of directors;

•

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our outstanding shares entitled to vote generally in the election of directors at the time the transaction commenced; or

•

on or after such time, the business combination is approved by the board of directors and authorized at a meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding shares entitled to vote generally in the election of directors that are not owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is any entity or person beneficially owning 15% or more of our outstanding shares entitled to vote generally in the election of directors or any entity or person affiliated with or controlling or controlled by any of these entities or persons and who beneficially owned 15% or more of our outstanding shares entitled to vote generally in the election of directors at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such person is an interested stockholder or an entity or person affiliated with or controlling or controlled by any of these entities or persons.

Under certain circumstances, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period. This provision may encourage companies interested in acquiring our Company to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Our Amended Certificate of Incorporation provides that BCP IV GrafTech Holdings LP and its affiliates and any of their respective direct or indirect transferees and any group as to which such persons are a party do not constitute “interested stockholders” for purposes of this provision.

Special Stockholder Meetings

Our Amended Certificate of Incorporation provides that special meetings of our stockholders may be called at any time only by or at the direction of the board of directors or the chair of the board of directors. Our Amended By-Laws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our Company.

Requirements for Advance Notification of Director Nominations and Stockholder Proposals

Our Amended By-Laws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not earlier than the opening of business 120 days prior, and not later than the close of business 90 days before, the first anniversary date of the immediately preceding annual meeting of stockholders. Our Amended By-Laws also specify requirements as to the form and content of a stockholder’s notice. Our Amended By-Laws provide that the board of directors may adopt by resolution the rules and regulations for the conduct of meetings. Our Amended By-Laws allow the chair of the meeting at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed.

These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of our Company.

Stockholder Action by Written Consent

Our Amended Certificate of Incorporation provides that stockholder action can be taken only at an annual meeting or special meeting of stockholders and cannot be taken by written consent in lieu of a meeting.

Supermajority Provisions

Our Amended Certificate of Incorporation and Amended By-Laws provide that the board of directors is expressly authorized to adopt, make, alter, amend or repeal our Amended By-Laws without a stockholder vote in any matter not inconsistent with the laws of the State of Delaware. Any adoption, alteration, amendment or repeal of our Amended By-Laws by our stockholders will require the affirmative vote of holders of at least 66 2/3% of the voting power of our outstanding common stock.

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares then entitled to vote is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage. Our Amended Certificate of Incorporation provides that it may be amended only by a vote of at least 66 2/3% of the voting power of our outstanding common stock.

The combination of the classification of our board of directors, the lack of cumulative voting and the supermajority voting requirements will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

These provisions may have the effect of deterring hostile takeovers or delaying or preventing changes in control of our management or our Company, such as a merger, reorganization or tender offer. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of us. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they may also inhibit fluctuations in the market price of our shares of common stock that could result from actual or rumored takeover attempts.

Authorized but Unissued or Undesignated Capital Stock

Our authorized capital stock consists of 300,000,000 shares of common stock and 30,000,000 shares of preferred stock. A large quantity of authorized but unissued shares may deter potential takeover attempts because of the ability of our board of directors to authorize the issuance of some or all of these shares to a friendly party, or to the public, which would make it more difficult for a potential acquirer to obtain control of us. This possibility may encourage persons seeking to acquire control of us to negotiate first with our board of directors. The authorized but unissued stock may be issued by the board of directors in one or more transactions. In this regard, our Amended Certificate of Incorporation grants the board of directors broad power to establish the rights and preferences of authorized and unissued preferred stock. The issuance of shares of preferred stock pursuant to the board of directors’ authority described above could decrease the amount of earnings and assets available for distribution to holders of common stock and adversely affect the rights and powers, including voting rights, of such holders and may have the effect of delaying, deferring or preventing a change of control. The board of directors does not currently intend to seek stockholder approval prior to any issuance of preferred stock, unless otherwise required by law.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders have appraisal rights in connection with a merger or consolidation of us. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Court of Chancery in the State of Delaware.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Choice of Forum

Our Amended Certificate of Incorporation provides that unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the sole and exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the DGCL, our Amended Certificate of Incorporation or Amended By-Laws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Any person or entity purchasing or otherwise acquiring any interest in our shares of common stock shall be deemed to have notice of and consented to the forum provisions in our Amended Certificate of Incorporation.

Limitation of Liability and Indemnification of Officers and Directors

Our Amended Certificate of Incorporation provides that no director shall be personally liable to us or any of our stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. Our Amended Certificate of Incorporation and Amended By-Laws provide that we will indemnify, hold harmless and advance expenses to the fullest extent permitted by the DGCL, any person made or threatened to be made a party to any action or is involved in a proceeding by reason of the fact that the person is or was our director or officer, or our director or officer who, while a director or officer, is or was serving at the request of the Company as a director, officer, employee, agent or manager of another corporation, partnership, limited liability company, joint venture, trust or other enterprise or non-profit entity, including service with respect to an employee benefit plan. Our Amended By-Laws also provide that, subject to applicable law, the Company may, by action of its board of directors, grant rights to indemnification and advancement of expenses to persons other than its directors and officers with such scope and effect as the board of directors may then determine. We have entered into customary indemnification agreements with each of our executive officers and directors that provide them, in general, with customary indemnification in connection with their service to us or on our behalf.

DESCRIPTION OF PREFERRED STOCK

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms that will apply to any debt securities that we may offer pursuant to this prospectus and an applicable prospectus supplement. The specific terms of any offered debt securities, and the extent to which the general terms described in this section apply to these debt securities, will be described in the applicable prospectus supplement at the time of the offering. The prospectus supplement, which we will file with the SEC, may or may not modify the general terms found in this prospectus. For a complete description of any series of debt securities, you should read both this prospectus and the prospectus supplement that applies to that series of debt securities.

In this section, the terms “we,” “our,” “us” and “GrafTech” refer solely to GrafTech International Ltd. (and not to any of its affiliates, including subsidiaries). As used in this prospectus, “debt securities” means the debentures, notes, bonds and other evidences of indebtedness that we may offer pursuant to this prospectus and an applicable prospectus supplement and authenticated by the relevant trustee and delivered under the applicable indenture. We may issue debt securities under an indenture (the “indenture”) to be entered into between us and U.S. Bank Trust Company, National Association, as trustee (the “trustee”), as supplemented from time to time, the form of which is filed as an exhibit to the registration statement of which this prospectus is a part. If a different trustee or a different indenture for a series of debt securities is used, those details will be provided in a prospectus supplement and the forms of any other indentures will be filed with the SEC at the time they are used.

We have summarized below the material provisions of the indenture and the debt securities, and indicated which material provisions will be described in an applicable prospectus supplement. For further information, you should read the indenture. The following summary is qualified in its entirety by the provisions of the indenture, including the provisions made part thereof by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

General

The indenture will not limit the aggregate principal amount of debt securities that may be issued under it. We may issue debt securities at one or more times in one or more series. Each series of debt securities may have different terms. The terms of any series of debt securities will be described in, or determined by action taken pursuant to, a resolution of our board of directors or a committee appointed by our board of directors or in a supplement to the indenture relating to that series.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of that series, except for the date of original issuance and the offering price, and will be consolidated with, and form a single series with, those outstanding debt securities.

The prospectus supplement relating to any series of debt securities that we may offer will state the price or prices at which the debt securities will be offered and will contain the specific terms of that series. These terms may include the following:

•

the title of the series;

•

•

our obligation, if any, to redeem or purchase securities of the series in whole or in part pursuant to any sinking fund or analogous provision or upon the happening of a specified event or at the option of a holder thereof and the period or periods within which, the price or prices at which, and the other terms and conditions upon which securities of the series will be redeemed or purchased, in whole or in part, pursuant to such an obligation;

•

if other than denominations of $2,000 and multiples of $1,000 thereafter, the denominations in which securities of the series are issuable;

•

if other than U.S. dollars, the currency or currencies (including currency unit or units) in which payments of principal of (and premium, if any) and interest, if any, on the securities of the series will or may be payable, or in which the securities of the series will be denominated, and the particular provisions applicable thereto;

•

if the payments of principal of (and premium, if any), or interest, if any, on the securities of the series are to be made, at our or a holder’s election, in a currency or currencies (including currency unit or units) other than that in which the securities are denominated or designated to be payable, the currency or currencies (including currency unit or units) in which the payments are to be made, the terms and conditions of the payments and the manner in which the exchange rate with respect to the payments will be determined, and the particular provisions applicable thereto;

•

if the amount of payments of principal of (and premium, if any) and interest, if any, on the securities of the series will be determined with reference to an index, formula or other method (which index, formula or method may be based, without limitation, on a currency or currencies (including currency unit or units) other than that in which the securities of the series are denominated or designated to be payable), the index, formula or other method by which those amounts will be determined;

•

whether, and the terms and conditions upon which, the securities of the series may or must be converted into our securities or exchanged for our securities or those of another enterprise;

•

if other than the principal amount thereof, the portion of the principal amount of securities of the series which will be payable upon declaration of acceleration of the maturity thereof pursuant to an event of default or the method by which that portion will be determined;

•

any modifications of or additions to the events of default or covenants with respect to securities of the series, or any modifications of or additions to subordination provisions with respect to any debt securities that are subordinated;

•

any other terms of the series.

Interest

Unless otherwise indicated in the applicable prospectus supplement, if any payment date with respect to debt securities falls on a day that is not a business day, we will make the payment on the next business day. The payment made on the next business day will be treated as though it had been made on the original payment date, and no interest will accrue on the payment for the additional period of time.

Ranking

Unless otherwise indicated in the applicable prospectus supplement, the debt securities, if senior debt securities, will be our direct, unconditional, unsecured and unsubordinated obligations and will rank pari passu with all of our other unsecured senior obligations. However, such senior debt securities will be effectively junior to all of our secured obligations to the extent of the value of the assets securing those obligations. Such debt securities will also be structurally subordinated to all liabilities, including trade payables and lease obligations, of our subsidiaries. The debt securities, if subordinated debt securities, will be our direct, unconditional, unsecured and subordinated obligations and will be junior in right of payment to our existing and future senior obligations. The extent of subordination of such subordinated debt securities will be described in an accompanying prospectus supplement.

Covenants

Except as described below or in the prospectus supplement with respect to any series of debt securities, neither we nor any subsidiary guarantors are restricted by the indenture from paying dividends or making distributions on our or their capital stock or purchasing or redeeming our or their capital stock. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, with certain exceptions, the indenture does not contain any covenants or other provisions that would limit our or any subsidiary guarantor’s right to incur additional indebtedness or limit the amount of additional indebtedness, including senior or secured indebtedness that we can create, incur, assume or guarantee.

Unless otherwise indicated in the applicable prospectus supplement, covenants contained in the indenture will be applicable to the series of debt securities to which the prospectus supplement relates so long as any of the debt securities of that series are outstanding.

Reporting

The indenture provides that we will file with the trustee and the SEC such information, documents and other reports as may be required pursuant to the Trust Indenture Act at the times and in the manner provided in the Trust Indenture Act.

Guarantees

One or more of our direct or indirect wholly-owned subsidiaries may fully and unconditionally guarantee any series of debt securities offered by this prospectus in the future. The term “subsidiary guarantors” with respect to a series of debt securities refers to those subsidiaries, if any, that guarantee that series of debt securities. We may file one or more post-effective amendments to our registration statement to add such potential subsidiary guarantors. The applicable prospectus supplement will name the subsidiary guarantors, if any, for that series of debt securities and will describe the terms of the guarantee by the subsidiary guarantors.

Consolidation, Merger and Sale of Assets

The indenture provides that neither we nor any subsidiary guarantor may consolidate or merge with or into, or sell or convey all or substantially all of our assets in any one transaction or series of related transactions to

another person, unless (other than a consolidation or merger of GrafTech and one or more subsidiary guarantors or two or more subsidiary guarantors, or a sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the assets of GrafTech to a subsidiary guarantor, a subsidiary guarantor to the Company or of a subsidiary guarantor to another subsidiary guarantor):

•

either we or a subsidiary guarantor, as the case may be, are the resulting, surviving or transferee corporation, or our successor is a corporation organized under the laws of the United States, any state or the District of Columbia and expressly assumes by supplemental indenture all of our obligations under the indenture and all the debt securities; and

•

immediately after giving effect to the transaction, no default or event of default has occurred and is continuing.

The term “default” for the purpose of this provision means any event that is, or with the passage of time or the giving of notice or both would become, an event of default.

Except in the case of a lease of all or substantially all of our assets or a subsidiary guarantor’s assets, the successor will be substituted for us or the subsidiary guarantor, as the case may be, in the indenture with the same effect as if it had been an original party to such indenture. Thereafter, the successor may exercise the rights and powers of GrafTech or such subsidiary guarantor under the indenture.

Events of Default, Notice and Waiver

In the indenture, the term “event of default” with respect to debt securities of any series means any of the following:

•

failure by us to pay interest, if any, on the debt securities of that series for 30 days after the date payment is due and payable;

•

failure by us to pay principal of or premium, if any, on the debt securities of that series when due, at maturity, upon any redemption, by declaration or otherwise;

•

failure by us or any subsidiary guarantor to comply with other covenants in the indenture or the debt securities of that series for 90 days after notice that compliance was required;

•

certain events of bankruptcy or insolvency of us or any subsidiary guarantor with respect to such series that is a significant subsidiary; and

•

if applicable, specified events involving the guarantees.

The term “significant subsidiary” for the purpose of this provision means any of our subsidiaries that would be a “significant subsidiary” as defined in Rule 1-02(w) of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

If an event of default (other than relating to certain events of bankruptcy or insolvency of us or breach of our reporting obligation) has occurred and is continuing, the trustee or the holders of not less than 25% in aggregate principal amount of the debt securities of that series may declare the entire principal of all the debt securities of the affected series to be due and payable immediately.

If an event of default relating to certain events of bankruptcy or insolvency of us or any subsidiary guarantor occurs and is continuing, then the principal amount of all of the outstanding debt securities and any accrued interest thereon will automatically become due and payable immediately, without any declaration or other act by the trustee or any holder.

The holders of not less than a majority in aggregate principal amount of the debt securities of any series may, after satisfying conditions, rescind and annul any of the above-described declarations and consequences involving the debt securities of that series, except a continuing default or event of default in the payment of principal of, or interest or premium, if any, on the debt securities of the affected series.

The indenture imposes limitations on suits brought by holders of debt securities of any series against us or any subsidiary guarantor. Except for actions for payment of overdue principal or interest, no holder of a debt security of any series may institute any action against us under the indenture unless:

•

the holder has previously given to the trustee written notice of an event of default and the continuance of that event of default;

•

the holder or holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have requested that the trustee pursue the remedy;

•

such holder or holders have offered to the trustee security or indemnity reasonably satisfactory to the trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

•

the trustee has not instituted the action within 60 days of the receipt of such notice, request and offer of indemnity; and

•

the trustee has not received inconsistent direction by the holders of a majority in principal amount of the outstanding debt securities of that series.

We will be required to file annually with the trustee a certificate, signed by an officer of our Company, stating whether or not the officer knows of any default by us in the performance, observance or fulfillment of any condition or covenant of the indenture.

Notwithstanding the foregoing, the sole remedy for any breach of our obligation under the indenture to file or furnish reports or other financial information pursuant to section 314(a)(1) of the Trust Indenture Act (or as otherwise required by the indenture) shall be the payment of liquidated damages, and the holders will not have any right under the indenture to accelerate the maturity of the debt securities of the affected series as a result of any such breach. If any such breach continues for 90 days after notice thereof is given in accordance with the indenture, we will pay liquidated damages to the holders of the debt securities of that series at a rate per annum equal to 0.25% per annum of the principal amount of the debt securities of the affected series from the 90th day following such notice to but not including the date on which the breach relating to the reporting obligations referred to in this paragraph shall have been cured or waived. The provisions of the indenture described in this paragraph will not affect the rights of the holders of the debt securities of any series in the event of the occurrence of any other event of default.

Modification and Waiver

Except as provided in the two succeeding paragraphs, the indenture provides that we, any subsidiary guarantors and the trustee thereunder may, with the consent of the holders of not less than a majority in aggregate principal amount of the debt securities of any series then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities of that series), voting as one class, add any provisions to, or change in any manner, eliminate or modify in any way the provisions of, the indenture or modify in any manner the rights of the holders of the debt securities of that series.

evidence the assumption by a successor corporation of our obligations under the indenture and the debt securities of any series in the case of a merger, amalgamation, consolidation or sale of all or substantially all of our assets;

•

provide for the issuance of additional debt securities of any series in accordance with the limitations set forth in the indenture as of the date of the indenture;

•

•

in the case of convertible or exchangeable debt securities of any series, subject to the provisions of the supplemental indenture for that series, to provide for conversion rights, exchange rights and/or repurchase rights of holders of that series in connection with any reclassification or change of our common stock or in the event of any amalgamation, consolidation, merger or sale of all or substantially all of the assets of us or our subsidiaries substantially as an entirety occurs;

•

in the case of convertible or exchangeable debt securities of any series, to reduce the conversion price or exchange price applicable to that series;

•

in the case of convertible or exchangeable debt securities of any series, to increase the conversion rate or exchange ratio in the manner described in the supplemental indenture for that series, provided that the increase will not adversely affect the interests of the holders of that series in any material respect; or

•

any other action to amend or supplement the indenture or the debt securities of any series as described in the prospectus supplement with respect to that series of debt securities.

We, any subsidiary guarantors and the trustee may not, without the consent of the holder of each outstanding debt security affected thereby:

•

•

reduce the aggregate principal amount on any debt security;

•

reduce the rate or amend or modify the calculation, or time of payment, of interest, including defaulted interest on any debt security;

•

impair the right to institute suit for the enforcement of any payment on any debt security when due, or otherwise make any change in the provisions of the indenture relating to waivers of past defaults or the rights of holders of any debt security to receive payments of principal of, or premium, if any, or interest on any debt security;

•

any other action to modify or amend the indenture or the debt securities of any series as may be described in the prospectus supplement with respect to that series of debt securities as requiring the consent of each holder affected thereby.

Defeasance

The indenture provides that we and any subsidiary guarantors will be discharged from any and all obligations in respect of the debt securities of any series (except for certain obligations to register the transfer or exchange of the debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold monies for payment in trust and to pay the principal of and interest, if any, on those debt securities), upon the deposit with the applicable trustee, in trust, of money and/or U.S. government obligations, which through the payment of interest and principal of the U.S. government obligations in accordance with their terms will provide money in an amount sufficient to pay any installment of principal and premium, if any, and interest, if any, on the debt securities of that series on the stated maturity date thereof in accordance with the terms of the indenture and the debt securities of that series. Also, the establishment of such a trust will be conditioned on the delivery by us or a subsidiary guarantor to the trustee of an opinion of counsel reasonably satisfactory to the trustee to the effect that, based upon applicable U.S. federal income tax law or a ruling published by the IRS, such a defeasance and discharge will not be deemed, or result in, a taxable event with respect to the holders. For the avoidance of doubt, such an opinion would require a change in current U.S. tax law.

We and any subsidiary guarantors may also omit to comply with the restrictive covenants, if any, of any particular series of debt securities, other than the covenant to pay the amounts due and owing with respect to that series. Any such omission will not be an event of default with respect to the debt securities of that series, upon the deposit with the applicable trustee, in trust, of money and/or U.S. government obligations, which through the payment of interest and principal of the U.S. government obligations in accordance with their terms will provide money in an amount sufficient to pay any installment of principal and premium, if any, and interest, if any, on the debt securities of that series on the stated maturity date thereof in accordance with the terms of the indenture and the debt securities of that series. Our and any subsidiary guarantors’ obligations under the indenture and the debt

securities of that series other than with respect to those covenants will remain in full force and effect. Also, the establishment of such a trust will be conditioned on the delivery by us or a subsidiary guarantor to the trustee of an opinion of counsel to the effect that such a defeasance and discharge will not be deemed, or result in, a taxable event with respect to the holders.

Satisfaction and Discharge

At our option, we may satisfy and discharge the indenture with respect to the debt securities of any series (except for specified obligations of the trustee and ours, including, among others, the obligations to apply money held in trust) when:

•

either (a) all debt securities of that series previously authenticated under the indenture have been delivered to the trustee for cancellation or (b) all debt securities of that series not yet delivered to the trustee for cancellation (i) have become due and payable by reason of the mailing of a notice of redemption or otherwise or (ii) will become due and payable within one year, and we or a subsidiary guarantor has irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the holders an amount sufficient to pay and discharge the entire indebtedness on debt securities of that series;

•

no default or event of default with respect to debt securities of that series has occurred or is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or violation of any other instrument to which we are bound;

•

we or a subsidiary guarantor have paid or caused to be paid all other sums payable by us under the indenture and any applicable supplemental indenture with respect to the debt securities of that series;

•

we have delivered irrevocable instructions to the trustee to apply the deposited funds toward the payment of securities of that series at the stated maturity date or the redemption date, as applicable; and

•

we have delivered to the trustee an officer’s certificate and an opinion of counsel stating that all conditions precedent relating to the satisfaction and discharge of the indenture as to that series have been satisfied.

Unclaimed Money

If money deposited with the trustee or paying agent for the payment of principal of, premium or accrued and unpaid interest, if any, on debt securities remains unclaimed for two years, the trustee and paying agent will pay the money back to us upon our request. However, the trustee and paying agent have the right to withhold paying the money back to us until they publish in a newspaper of general circulation in the City of New York, or mail to each holder, a notice stating that the money will be paid back to us if unclaimed after a date no less than 30 days from the publication or mailing. After the trustee or paying agent pays the money back to us, holders of debt securities entitled to the money must look to us for payment, subject to applicable law, and all liability of the trustee and the paying agent with respect to the money will cease.

Purchase and Cancellation

The registrar and paying agent will forward to the trustee any debt securities surrendered to them for transfer, exchange or payment, and the trustee will promptly cancel those debt securities in accordance with its customary procedures. We will not issue new debt securities to replace debt securities that we have paid or delivered to the trustee for cancellation or that any holder has converted.

We may, to the extent permitted by law, purchase debt securities in the open market or by tender offer at any price or by private agreement. We may, at our option and to the extent permitted by law, reissue, resell or surrender to the trustee for cancellation any debt securities we purchase in this manner; provided that we not

reissue or resell those debt securities if upon reissuance or resale, they would constitute “restricted securities” within the meaning of Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”). Debt securities surrendered to the trustee for cancellation may not be reissued or resold and will be promptly cancelled.

Replacement of Debt Securities

We will replace mutilated, lost, destroyed or stolen debt securities at the holder’s expense upon delivery to the trustee of the mutilated debt securities or evidence of the loss, destruction or theft of the debt securities satisfactory to the trustee and us. In the case of a lost, destroyed or stolen debt security, we or the trustee may require, at the expense of the holder, indemnity satisfactory to us and the trustee.

Regarding the Trustee

U.S. Bank Trust Company, National Association, is the trustee under the indenture. Except during the continuance of an event of default, the trustee will perform only such duties as are specifically set forth in the indenture. During the existence of an event of default, the trustee will exercise such of the rights and powers vested in it under the indenture and use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs. The holders of a majority in principal amount of the then outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. Subject to these provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of debt securities, unless such holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

Pursuant and subject to the Trust Indenture Act, the trustee will be permitted to engage in other transactions with us; however, if the trustee acquires any conflicting interest, it would be required to eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign.

No individual liability of directors, officers, employees, incorporators, stockholders or agents

The indenture provides that none of the past, present or future directors, officers, employees, incorporators, stockholders, other owners or agents of GrafTech or any subsidiary guarantor in their capacity as such will have any liability for any of our obligations under the debt securities of any series or the indenture. Each holder of debt securities of any series by accepting a debt security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the debt securities. The waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Governing law

The indenture and debt securities of each series are governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF DEPOSITARY SHARES

We may issue fractional interests in shares of common or preferred stock, rather than shares of common or preferred stock, with those rights and subject to the terms and conditions that we may specify in a related prospectus supplement. If we do so, we will provide for a depositary (either a bank or trust company depositary that has its principal office in the United States) to issue receipts for depositary shares, each of which will represent a fractional interest in a share of common or preferred stock. The shares of common or preferred stock

underlying the depositary shares will be deposited under a deposit agreement between us and the depositary. The prospectus supplement will include the name and address of the depositary.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt or equity securities. Each warrant will entitle the holder to purchase for cash the amount of debt or equity securities at the exercise price stated or determinable in the prospectus supplement for the warrants. We may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in a related prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that we may offer will contain the specific terms of the warrants. These terms will include some or all of the following:

•

the title of the warrants;

•

the price or prices at which the warrants will be issued;

•

the designation, amount and terms of the securities for which the warrants are exercisable;

•

the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each other security;

•

the aggregate number of warrants;

•

any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

•

the price or prices at which the securities purchasable upon exercise of the warrants may be purchased;

•

the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable, if applicable;

•

a discussion of any material U.S. federal income tax considerations applicable to the exercise of the warrants;

•

the date on which the right to exercise the warrants will commence, and the date on which the right will expire;

•

the maximum or minimum number of warrants that may be exercised at any time;

•

information with respect to book-entry procedures, if any; and

•

any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including contracts obligating holders to purchase from us and us to sell to the holders, a specified number of shares of common stock, preferred stock or depositary shares at a future date or dates. Alternatively, the purchase contracts may obligate us to purchase from holders, and obligate holders to sell to us, a specified or varying number of shares of common stock, preferred stock or depositary shares. The consideration per share of common stock or preferred stock or per depositary share may be fixed at

the time the purchase contracts are issued or may be determined by a specific reference to a formula set forth in the purchase contracts. The purchase contracts may provide for settlement by delivery by us or on our behalf of shares of the underlying security, or they may provide for settlement by reference or linkage to the value, performance or trading price of the underlying security. The purchase contracts may be issued separately or as part of purchase units consisting of a purchase contract and debt securities, preferred stock or debt obligations of third parties, including U.S. treasury securities, other purchase contracts or common stock, or other securities or property, securing the holders’ obligations to purchase or sell, as the case may be, the common stock, preferred stock, depositary shares or other security or property under the purchase contracts. The purchase contracts may require holders to secure their obligations thereunder in a specified manner and may provide for the prepayment of all or part of the consideration payable by holders in connection with the purchase of the underlying security or other property pursuant to the purchase contracts.

The securities related to the purchase contracts may be pledged to a collateral agent for our benefit pursuant to a pledge agreement to secure the obligations of holders of purchase contracts to purchase the underlying security or property under the related purchase contracts. The rights of holders of purchase contracts to the related pledged securities will be subject to our security interest therein created by the pledge agreement. No holder of purchase contracts will be permitted to withdraw the pledged securities related to such purchase contracts from the pledge arrangement.

DESCRIPTION OF UNITS

We may issue units comprising one or more securities described in this prospectus in any combination. The particular terms of the units will be described in a related prospectus supplement.

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus from time to time, in one or more or any combination of the following transactions:

•

to or through underwriters or dealers;

•

directly to a limited number of purchasers or to a single purchaser;

•

in “at the market offerings,” within the meaning of Rule 415(a)(4) under the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

•

through agents, including in a block trade in which a broker-dealer will attempt to sell the offered securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

through purchases by a broker-dealer as principal and resale by the broker-dealer for its account pursuant to this prospectus; or

•

through any other method permitted by applicable law.

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 so 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 or borrowed from us or others to settle those sales or to close out any related open borrowings of stock and may use securities received from us or others 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, if not identified in

this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment to the registration statement of which this prospectus forms a part).

The applicable prospectus supplement will set forth the terms of the offering of the securities covered by this prospectus, including:

•

the name or names of any underwriters, dealers or agents and the amounts of securities underwritten or purchased by each of them;

•

the initial public offering price of the securities, if a fixed price offering, and the proceeds to us and any discounts, commissions or concessions allowed or reallowed or paid to dealers; and

•

any securities exchanges on which the securities may be listed.

Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Underwriters or the third parties described above may offer and sell the offered securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. If underwriters are used in the sale of any securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to customary conditions. The underwriters will be obligated to purchase all of the offered securities if they purchase any of the offered securities.

We may sell the securities at prices then prevailing or related to the then current market price or at negotiated prices. The offering price of the securities from time to time will be determined by us and, at the time of the determination, may be higher or lower than the market price of the securities on any securities exchanges on which the securities may be listed.

We may sell the securities through agents from time to time. The applicable prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at the public offering price set forth in the applicable prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the applicable prospectus supplement, and the applicable prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Certain persons participating in this offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities.

Specifically, in connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, the underwriters may over-allot and may bid for, and purchase, the securities in the open market.

Any agents, underwriters and other third parties described above that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We may have agreements with the agents, underwriters and those other third parties to indemnify them against specified civil liabilities, including liabilities under the Securities Act, or

to contribute to payments they may be required to make in respect of those liabilities. Agents, underwriters and those other third parties may engage in transactions with or perform services for us in the ordinary course of their businesses.

To comply with applicable state securities laws, the securities offered by this prospectus will be sold, if necessary, in such jurisdictions only through registered or licensed brokers or dealers. In addition, securities may not be sold in some states absent registration or pursuant to an exemption from applicable state securities laws.

LEGAL MATTERS

Certain legal matters relating to the securities described in the prospectus, including the validity of such securities, will be passed upon for us by Jones Day. Certain legal matters in connection with any offering, including the validity of the securities described in the prospectus, will be passed upon for any underwriters or agents, as the case may be, by counsel identified in the prospectus supplement with respect to any offering.

Item 15

Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with specified actions, suits and proceedings whether civil, criminal, administrative, or investigative, other than a derivative action by or in the right of the corporation, if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation’s certificate of incorporation, bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

Our Amended and Restated Certificate of Incorporation, as amended (“Amended Certificate of Incorporation”) and Amended and Restated By-Laws (“Amended By-Laws”) provide for indemnification of directors and officers to the fullest extent permitted by law, including payment of expenses in advance of resolution of any such matter. Our Amended Certificate of Incorporation eliminates the potential personal monetary liability of our directors to the Company or its stockholders for breaches of their duties as directors except as otherwise required under the DGCL.

We have entered into separate indemnification agreements with our directors and officers. Each indemnification agreement provides, among other things, for indemnification to the fullest extent permitted by law and our Amended Certificate of Incorporation and Amended By-Laws against any and all expenses, judgments, fines, penalties and amounts paid in settlement of any claim. The indemnification agreements provide for the advancement or payment of all expenses to the indemnitee and for reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our Amended Certificate of Incorporation and Amended By-Laws.

II-1

We maintain standard policies of insurance under which coverage is provided (a) to our directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, and (b) to us with respect to payments which we may make to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

Any underwriting agreement, the form of which will be filed as an Exhibit 1 to this registration statement, will provide for indemnification, under certain circumstances, by the underwriters of us and our officers and directors for certain liabilities arising under the Securities Act or otherwise.

Item 16

Exhibits and Financial Statement Schedules.

(a) Exhibits: The list of exhibits is set forth beginning on page II-4 of this registration statement and is incorporated herein by reference.

(b) Financial Statement Schedules: No financial statement schedules are provided because the information called for is not applicable or is shown in the financial statements or notes thereto.

Item 17

Undertakings.

(a) 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 (the “Securities Act”);

(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 Securities and Exchange Commission (the “SEC”) pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing 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 (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the registration statement is on Form S-3 and 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, as amended (the “Exchange Act”), 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, 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.

II-2

(4) That, for the purpose of determining liability under the Securities Act 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 the 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 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.

(5) That, for the purpose of determining liability of the registrant under the Securities Act 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.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) 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.

(c) Insofar as indemnification for liabilities arising under the Securities Act 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 SEC such indemnification is against public policy as expressed in the Act 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

II-3

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 and will be governed by the final adjudication of such issue.
