SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents incorporated herein and therein by reference contain certain forward-looking statements, including, but not limited to, certain plans, expectations, goals, projections, and statements, which are not historical facts and are subject to numerous assumptions, risks, and uncertainties. Statements that do not describe historical or current facts, including statements about beliefs and expectations, are forward-looking statements. Forward-looking statements may be identified by words such as expect, anticipate, believe, intend, estimate, plan, target, goal, or similar expressions, or future or conditional verbs such as will, may, might, should, would, could, or similar variations. The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995, as amended.

While there is no assurance that any list of risks and uncertainties or risk factors is complete, below are certain factors which could cause actual results to differ materially from those contained or implied in the forward-looking statements: changes in general economic, political, or industry conditions; uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Federal Reserve; volatility and disruptions in global capital and credit markets; movements in interest rates; competitive pressures on product pricing and services; success, impact, and timing of our business strategies, including market acceptance of any new products or services implementing our “Fair Play” banking philosophy; the nature, extent, timing, and results of governmental actions, examinations, reviews, reforms, regulations, and interpretations, including those related to the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Basel III regulatory capital reforms, as well as those involving the Office of the Comptroller of the Currency (“OCC”), Federal Reserve, FDIC, and Consumer Financial Protection Bureau; and other factors that may affect our future results. Additional factors that could cause results to differ materially from those described above can be found in our 2017 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, and documents subsequently filed by us with the SEC. We assume no obligation to update any forward-looking statements. The foregoing list of factors is not exhaustive. For discussion of these and other factors that may cause actual results to differ from expectations, look under the captions “Forward-Looking Statements” and “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2017 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, as filed with the SEC, and in this prospectus supplement and the accompanying prospectus.

All forward-looking statements speak only as of the date they are made and are based on information available at that time. We do not assume any obligation to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements. Please carefully review and consider the various disclosures made in this document, in the accompanying prospectus and in our other reports filed with the SEC for more information about the risks and other factors that may affect our business, results of operations, financial condition or prospects.

RISK FACTORS

An investment in our notes involves certain risks. You should carefully consider the risks described below and the risk factors included in our Annual Report on Form 10-K for the year ended December 31, 2017 and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, as well as the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in any forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus supplement and the accompanying prospectus.

The notes are our obligations and not obligations of our subsidiaries and will be structurally subordinated to the claims of our subsidiaries’ creditors.

The notes are exclusively our obligations and not those of our subsidiaries. We are a holding company that conducts substantially all of our operations through our bank and non-bank subsidiaries. As a result, our ability to make payments on the notes will depend primarily upon the receipt of dividends and other distributions from our subsidiaries. If we do not receive sufficient cash dividends and other distributions from our subsidiaries, it is unlikely that we will have sufficient funds to make payments on the notes.

Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds to pay our obligations on the notes, whether by dividends, distributions, loans or other payments. In addition, any dividend payments, distributions, loans or advances to us by our subsidiaries in the future will require the generation of future earnings by our subsidiaries and may require regulatory approval. There are statutory and regulatory limitations on the payment of dividends by the Bank to us, as well as by us to our stockholders. The Bank may not, without prior regulatory approval, pay a dividend in an amount greater than its undivided profits. If the Bank is unable to make dividend payments to us and sufficient capital is not otherwise available, we may not be able to make principal and interest payments on our debt, including the notes.

In addition, our right to participate in any distribution of assets of any of our subsidiaries upon the subsidiary’s liquidation or otherwise will generally be subject to the prior claims of creditors of that subsidiary. Your ability as a holder of the notes to benefit indirectly from that distribution also will be subject to these prior claims. The notes are not guaranteed by any of our subsidiaries. As a result, the notes will be structurally subordinated to all existing and future liabilities and obligations of our subsidiaries, including deposits, which means that our subsidiaries’ creditors will be paid from our subsidiaries’ assets before holders of the notes would have any claims to those assets. Therefore, you should look only to our assets for payments on the notes. At March 31, 2018, the aggregate amount of all debt and other liabilities of our subsidiaries, including deposits, was approximately $89.4 billion. Our subsidiaries may incur additional debt and liabilities in the future, all of which would rank structurally senior to the notes. See “Capitalization” below for our outstanding debt as adjusted to give effect to this offering.

The notes will be effectively junior to all of our and our subsidiaries’ secured indebtedness.

The notes will be effectively subordinated to any of the existing and future secured debt we or our subsidiaries may incur, to the extent of the value of the assets securing such debt. In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized, any debt that ranks ahead of the notes will be entitled to be paid in full from our assets before any payment may be made with respect to the notes. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same ranking as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we may not

S-5

have sufficient assets to pay amounts due on the notes. As a result, if holders of the notes receive any payments, they may receive less, ratably, than holders of secured indebtedness.

There are limited covenants in the indenture pursuant to which we will issue the notes.

Neither we nor any of our subsidiaries is restricted from incurring additional debt or other liabilities, including additional senior debt, under the indenture pursuant to which we will issue the notes. If we incur additional debt or liabilities, our ability to pay our obligations on the notes could be adversely affected. We expect to incur, from time to time, additional debt and other liabilities. In addition, we are not restricted under the indenture from granting security interests over our assets, except to the extent described under “Description of Notes—Merger, Consolidation or Sale of Assets” and “Description of Notes—Certain Covenants” in this prospectus supplement, or from paying dividends or issuing or repurchasing our securities.

In addition, there are no financial covenants in the indenture. You are not protected under the indenture in the event of a highly leveraged transaction, reorganization, a default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect you, except to the extent described under “Description of Notes—Merger, Consolidation or Sale of Assets” and “Description of Notes—Certain Covenants” included in this prospectus supplement.

The notes are not insured or guaranteed by the Federal Deposit Insurance Corporation.

The notes are not savings accounts, deposits or other obligations of a bank and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality.

You may be unable to sell the notes because there is no public trading market for the notes.

The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or included in any automated quotation system. Consequently, the notes will be relatively illiquid and you may be unable to sell your notes. Although the representatives of the underwriters have advised us that, following completion of the offering of the notes, one or more of the underwriters currently intend to make a secondary market in the notes, they are not obligated to do so and may discontinue any market-making activities at any time without notice. Accordingly, a trading market for the notes may not develop or any such market may not have sufficient liquidity.

If a trading market for the notes develops, changes in our credit ratings or the debt markets could adversely affect the liquidity and market price of the notes.

If a trading market develops, the liquidity and prices of the notes will depend on many factors, including: (i) our credit ratings with major credit rating agencies; (ii) the prevailing interest rates being paid by other companies similar to us; (iii) our financial condition, financial performance and future prospects; and (iv) the overall condition of the financial markets.

The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and may fluctuate in the future. Such fluctuations could have an adverse effect on the liquidity and price of the notes.

In addition, credit rating agencies periodically review their ratings and ratings methodologies for the companies that they follow, including us and the Bank. A negative change in ratings or outlook could have an adverse effect on the liquidity and price of the notes.

A credit rating is not a recommendation to buy, sell or hold securities and may be revised, suspended or withdrawn by the credit rating agency at any time.

CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES

The table below sets forth Huntington’s consolidated ratios of earnings to fixed charges for the periods presented. For purposes of computing these ratios, earnings represent income before income taxes plus fixed charges. Fixed charges include all interest expense and the portion deemed representative of the interest factor of rent expense. These ratios are presented both including and excluding interest on deposits.

S-7

CAPITALIZATION

The following table sets forth Huntington’s consolidated cash and cash equivalents and consolidated capitalization as of March 31, 2018, on an actual basis and on an adjusted basis giving effect to the issuance and sale of the notes offered by this prospectus supplement and does not reflect the issuance and sale of notes by the Bank in the concurrent offering, see “Summary of the Offering—Concurrent Offering,” and the use of the net proceeds from the sale of the notes as described under “Use of Proceeds” in this prospectus supplement, after deducting the underwriting discount and our other offering fees and expenses. You should read the following table together with “Use of Proceeds” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Huntington’s consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2017 and “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the condensed consolidated financial statements and notes thereto in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, which are incorporated by reference in this prospectus supplement and the accompanying prospectus.

S-8

USE OF PROCEEDS

The net proceeds to us from the sale of the notes, after the deduction of the underwriting discount and estimated expenses payable by us, will be approximately $494,887,750, and will be used by us for general corporate purposes, which may include, among other things, funding asset growth of our subsidiaries.

S-9

DESCRIPTION OF NOTES

General

The notes will be a series of our senior debt securities. The notes will be issued under a senior indenture, dated as of December 29, 2005, as amended and supplemented by a supplemental indenture, to be dated as of May 15, 2018, between us and The Bank of New York Mellon Trust Company, N.A. as successor to JPMorgan Chase Bank, a national banking association, as trustee. Throughout this description of the notes, we refer to both the senior indenture and supplemental indenture together as the “indenture.” The trustee’s main role is to enforce your rights against us if we default. The following description of the notes may not be complete and is subject to and qualified in its entirety by reference to the indenture. Wherever we refer to particular sections or defined terms of the indenture, it is our intent that those sections or defined terms will be incorporated by reference in this prospectus supplement.

The notes will be issued in fully registered book-entry form without coupons and in denominations of $2,000 and integral multiples of $1,000 in excess thereof. We do not intend to apply for the listing of the notes on any securities exchange. The notes will be unsecured and unsubordinated and will rank equally among themselves and with all of our other unsecured and unsubordinated indebtedness. The notes will not be guaranteed by any of our subsidiaries. Our subsidiaries may, without notice or consent of the holders of the notes, incur additional debt or liabilities in the future, all of which would rank structurally senior to the notes. Huntington may from time to time, without notice or consent of the holders of the notes, incur additional senior indebtedness ranking equally with the notes, as well as additional subordinated indebtedness ranking junior to the notes. As of March 31, 2018, the aggregate amount of all debt and other liabilities of our subsidiaries, including deposits, was approximately $89.4 billion.

Since we are a holding company, our rights and the rights of our creditors, including holders of the notes, to participate in the assets of any of our subsidiaries upon the liquidation or reorganization of any of our subsidiaries will be subject to prior claims of the creditors of any such subsidiary, including, in the case of the Bank, its depositors, except to the extent that we are a creditor of such subsidiary with recognized claims against the subsidiary. Claims on our subsidiaries by creditors other than us may include claims with respect to long-term debt and substantial obligations with respect to deposit liabilities, federal funds purchased, securities sold under repurchase agreements, other short-term borrowings and various other financial obligations.

The notes will be subject to defeasance under the conditions described below in “—Discharge, Defeasance and Covenant Defeasance.” No additional amounts or make-whole amounts, as those terms are defined in the indenture, will be payable with respect to the notes.

The notes are not savings accounts, deposits or other obligations of any of our bank or non-bank subsidiaries and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve or any other governmental agency or instrumentality.

The notes will initially be limited to an aggregate principal amount of $500,000,000. We may, without the consent of the holders of the notes, increase the principal amount of the notes by issuing additional notes in the future with the same terms and conditions, except for any differences in the issue date, the issue price and interest accrued prior to the date of issuance of the additional notes, and with the same CUSIP number as the notes offered by this prospectus supplement; provided that if any additional notes are not fungible with the notes offered by this prospectus supplement for U.S. federal income tax purposes, such additional notes will be issued under a separate CUSIP number. The notes offered by this prospectus supplement and any additional notes would rank equally and ratably and would be treated as a single series for all purposes under the indenture.

The notes will mature at 100% of their principal amount on May 15, 2025 (the “maturity date”).

The notes will not be subject to repayment at the option of the holder at any time prior to maturity and will not be entitled to any sinking fund.

S-10

Payments of principal and interest to owners of the book-entry interests described below are expected to be made in accordance with the procedures of The Depository Trust Company and its participants, including Clearstream Banking, société anonyme, and Euroclear Bank S.A./N.V., as operator of the Euroclear System.

Interest

The notes will bear interest at an annual rate equal to 4.000%. Interest on the notes will be payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2018, to the persons in whose names the notes are registered at the close of business on the preceding May 1 and November 1, respectively, of each year. Interest on the notes at the maturity date will be payable to the persons to whom principal is payable. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. Interest payments on the notes will be the amount of interest accrued from and including May 15, 2018 or the most recent interest payment date on which interest has been paid to but excluding the next such interest payment date or the maturity date, as the case may be.

If an interest payment date or the maturity date falls on a day that is not a business day, the related payment of interest and principal will be made on the next day that is a business day, and no interest on the notes or such payment will accrue for the period from and after such interest payment date or maturity date, as the case may be.

When we refer to a “business day” with respect to the notes, we mean any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close.

Ranking

The notes will be senior unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness and will be effectively subordinated to our existing and future secured indebtedness, to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to the existing and future indebtedness of our subsidiaries. Because we are a holding company, our right to participate in any distribution of the assets of our banking or nonbanking subsidiaries, upon a subsidiary’s dissolution, winding-up, liquidation or reorganization or otherwise, and thus the ability of a holder of notes to benefit indirectly from such distribution, is subject to prior claims of creditors of any such subsidiary, except to the extent that we may be a creditor of that subsidiary and our claims are recognized. There are legal limitations on the extent to which some of our subsidiaries, including the Bank, may extend credit, pay dividends or otherwise supply funds to, or engage in transactions with, us or some of our other subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on the notes or to provide us with funds to pay our obligations on the notes, whether by dividends, distributions, loans or other payments. Our subsidiaries may, without notice or consent of the holders of the notes, incur additional debt and liabilities in the future, all of which would rank structurally senior to the notes. As of March 31, 2018, our subsidiaries had, in the aggregate, outstanding debt and other liabilities, including deposits, of approximately $89.4 billion. All of such debt and other liabilities would rank structurally senior to the notes in case of liquidation or otherwise. As of March 31, 2018, Huntington Bancshares Incorporated (parent company only) had approximately $2.3 billion of outstanding senior debt and approximately $0.5 billion of outstanding subordinated and junior subordinated debt.

Redemption

The notes will not be subject to redemption at our option at any time prior to April 15, 2025 (one month prior to their maturity date). At any time on or after April 15, 2025, we may, at our option, upon not less than 30 or more than 60 days’ prior notice, redeem all or any portion of the notes at a redemption price equal to 100% of the principal amount of the notes. Holders of any notes redeemed will also receive accrued and unpaid interest thereon to the date of redemption.

S-11

If any notes are redeemed, the redemption price payable to the holder of any notes called for redemption will be payable on the applicable redemption date against the surrender to us or our agent of any certificate(s) evidencing the notes called for redemption.

The notes will not be subject to repayment at the option of the holder at any time prior to maturity and will not be entitled to any sinking fund.

Merger, Consolidation or Sale of Assets

We may consolidate with, or sell, lease or otherwise transfer all or substantially all of our assets to, or merge with or into, any other corporation, trust or other entity, provided that:

Upon any such consolidation, merger, or sale, the successor corporation formed, or into which we are merged or to which we are sold, shall succeed to, and be substituted for, us under the indenture.

This covenant would not apply to any recapitalization transaction, change of control of us or a transaction in which we incur a large amount of additional debt unless the transactions or change of control included a merger or consolidation or transfer of all or substantially all of our assets. There are no covenants or other provisions in the indenture providing for a put or increased interest or that would otherwise afford holders of the notes additional protection in the event of a recapitalization transaction, a change of control of us or a transaction in which we incur or acquire a large amount of additional debt.

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the property or assets of a person.

Certain Covenants

Maintenance of Properties. We will cause all of our material properties used or useful in the conduct of our business or the business of any of our subsidiaries to be maintained and kept in good condition, repair, and working order and supplied with all necessary equipment and we will cause to be made all necessary repairs,

S-12

renewals, replacements, betterments, and improvements for those properties, as we in our judgment believe is necessary so that we may carry on the business related to those properties properly and advantageously at all times; provided, however, that we will not be prevented from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in our judgment, desirable in the conduct of our business or the business of any of our subsidiaries and not disadvantageous in any material respect to the holders of the notes.

Payment of Taxes and Other Claims. We will pay or discharge, or cause to be paid or discharged, before they become delinquent,

provided, however, that we will not be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings and for which adequate provision is made.

Waiver of Certain Covenants. We may choose not to comply with any term, provision or condition of certain covenants contained in the indenture, or with certain other terms, provisions or conditions with respect to the notes (except any such term, provision or condition which could not be amended without the consent of all holders of the notes), if before the time for compliance with the covenant, term, provision or condition, the holders of at least a majority in principal amount of the notes either waive compliance in that instance or generally waive compliance with that covenant, provision or condition. Unless the holders of the notes expressly waive compliance with a covenant and the waiver has become effective, our obligations and the duties of the trustee in respect of the term, provision, or condition will remain in full force and effect.

Sale or Issuance of Capital Stock in Principal Subsidiary Bank. We will not be permitted, pursuant to the covenants in the indenture, directly or indirectly, to do any of the following:

The term “principal subsidiary bank” means any subsidiary bank, the consolidated assets of which constitute 50% or more of our consolidated assets. As of the date of this prospectus supplement, our only principal subsidiary bank is the Bank. The indenture does not restrict the ability of the principal subsidiary bank to sell or dispose of assets.

The foregoing covenant in the indenture, however, does not prohibit any of the following:

S-13

Events of Default, Notice and Waiver

Each of the following “Events of Default” set forth in the indenture will be applicable to the notes:

If there is a continuing Event of Default under the indenture with respect to the notes, then the trustee or the holders of not less than 25% of the total principal amount of the notes may declare immediately due and payable the principal amount of the notes.

S-14

If an event of default occurs as a result of our bankruptcy, insolvency or reorganization, the principal amount of the notes shall become immediately due and payable automatically, and without any declaration or other action on the part of the trustee or any holder.

However, at any time after a declaration of acceleration with respect to the notes then outstanding has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the notes may rescind and annul such declaration and its consequences if:

The indenture also provides that the holders of not less than a majority in principal amount of the notes may waive any past default with respect to the notes and its consequences, except a default consisting of:

The trustee is generally required to give notice to the holders of the notes within 90 days of a default of which the trustee has actual knowledge under the indenture unless the default has been cured or waived.

The indenture provides that no holder of the notes may institute a proceeding with respect to the indenture or for any remedy under the indenture, unless such holder has previously given notice to the trustee of an Event of Default and the trustee fails to act for 60 days after:

Subject to provisions in the indenture relating to the trustee’s duties in case of default, the trustee is not under an obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders of the notes, unless the holders of the notes have offered to the trustee reasonable security or indemnity. Subject to these provisions for the indemnification of the trustee, the holders of not less than a majority in principal amount of the notes will have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee. However, the trustee may refuse to follow any direction which is in conflict with any law or the indenture or which may involve the trustee in personal liability.

Within 120 days after the close of each fiscal year, we must deliver to the trustee a certificate, signed by one of several specified officers, stating such officer’s knowledge of our compliance with all the conditions and covenants under the indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status of the noncompliance.

Modification of the Indenture

Modification and amendment of the indenture may be made only with the consent of the holders of not less than a majority in principal amount of the notes. However, no modification or amendment may, without the consent of each holder affected thereby, do any of the following:

We and the trustee may modify or amend the indenture, without the consent of any holder of the notes for any of the following purposes:

Discharge, Defeasance and Covenant Defeasance

Under the indenture, we may discharge certain obligations to holders of the notes that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become due and

S-16

payable within one year. We can discharge these obligations by irrevocably depositing with the trustee funds in United States dollars in an amount sufficient to pay the entire indebtedness on the notes, including the principal of and interest payable on the notes to the date of the deposit, if the notes have become due and payable, or to the maturity date, if the notes have not yet become due and payable.

We may also elect either of the following:

If we choose to defease and discharge our obligations under the covenants with respect to the notes, any failure to comply with the obligations imposed on us by the covenants will not constitute a default or an Event of Default with respect to the notes. However, to make either election, we must irrevocably deposit with the trustee, in trust, an amount, in United States dollars, in United States government obligations or both, that will provide sufficient funds to pay the principal of and interest on the notes on the relevant scheduled due dates.

We may defease and discharge our obligations as described in the preceding paragraphs only if, among other things:

S-17

Same-Day Settlement and Payment

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System.

Trustee

The Bank of New York Mellon Trust Company, N.A. will act as trustee for the notes. From time to time, we and some of our subsidiaries may maintain deposit accounts and conduct other banking transactions, including lending transactions, with the trustee and its affiliates in the ordinary course of business. Additionally, we maintain banking relationships with The Bank of New York Mellon Trust Company, N.A. and its affiliates in the ordinary course of business. These banking relationships include The Bank of New York Mellon Trust Company, N.A. serving as trustee under the indenture involving our existing debt securities, serving as trustee in connection with trust preferred securities that were issued by certain of our financing trusts, and providing us with general banking services. Upon the occurrence of an Event of Default or an event which, after notice or lapse of time or both, would become an Event of Default under the notes, or upon the occurrence of a default under another indenture under which The Bank of New York Mellon Trust Company, N.A. serves as trustee, the trustee may be deemed to have a conflicting interest with respect to the other debt securities as to which we are not in default for purposes of the Trust Indenture Act and, accordingly, may be required to resign as trustee under the indenture. In that event, we would be required to appoint a successor trustee.

The trustee will have all of the duties and responsibilities specified under the Trust Indenture Act.

The trustee, in any of its capacities under the indenture, has not participated in the preparation of this Prospectus Supplement and does not assume responsibility for its contents, including, for avoidance of doubt, any reports, financial statement, or any other collateral information related to or referred to herein. No representation, warranty or undertaking, express or implied, is made and no responsibility or liability is accepted by the trustee as to the accuracy or completeness of the information contained or incorporated in this Prospectus Supplement or any other information provided by Huntington in connection with the offering of the notes. The trustee does not have any liability in relation to the information contained or incorporated by reference in this Prospectus Supplement or any other information provided by Huntington in connection with the offering of the notes or their distribution.

Miscellaneous

We, or our affiliates, may from time to time purchase any of the notes that are then outstanding, by tender in the open market or by private agreement.

Notices

Any notices required to be given to the holders of the notes will be given to DTC.

Governing Law

The indenture and the notes are governed by and will be construed in accordance with the laws of the State of New York.

S-18

BOOK-ENTRY, DELIVERY AND FORM

The Depository Trust Company, which we refer to along with its successors in this capacity as “DTC,” will act as securities depository for the notes. The notes will be issued only as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One or more fully registered global security certificates, representing the total aggregate number of notes, will be issued for the notes and will be deposited with the trustee as custodian for DTC.

Investors may elect to hold beneficial interests in the global security certificates representing the notes through either DTC, in the United States, Clearstream Banking, société anonyme (“Clearstream”), and Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), if they are participants in these systems, or indirectly through organizations which are participants in these systems.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC, in turn, is owned by a number of Direct Participants of DTC and members of the National Securities Clearing Corporation, Fixed Income Clearing Corporation, and Emerging Markets Clearing Corporation (also subsidiaries of DTCC), as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the Financial Industry Regulatory Authority (“FINRA”). Access to the depository system is also available to others, such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The DTC rules applicable to DTC’s participants are on file with the SEC. More information about DTC can be found at www.dtcc.com or www.dtc.org.

Purchase of notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the notes on DTC’s records. The ownership interest of each actual purchaser (which we refer to as “beneficial owners”) of the notes will be recorded on the Direct or Indirect Participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the notes except in the event that use of the book-entry system for the notes is discontinued.

To facilitate subsequent transfers, all global security certificates deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of the notes with the trustee as custodian for DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes; DTC’s records reflect only the identity of the Direct Participants to whose accounts the notes are credited, which may or may not be the beneficial owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

S-19

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct and Indirect Participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to any notes unless authorized by a Direct Participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the notes are credited on the record date (identified in a listing attached to the omnibus proxy).

If DTC notifies us that it is unwilling or unable to continue as depository for the global securities relating to the notes or if at any time DTC ceases to be a clearing agency registered under the Exchange Act, if so required by applicable law or regulation, we will appoint a successor depository. If we do not appoint such successor depository within 90 days after we receive such notice or become aware of such unwillingness, inability or ineligibility, or an Event of Default under the indenture with respect to the notes has occurred and is continuing and the beneficial owners representing a majority in principal amount of the notes advise DTC to cease acting as depository for the notes, we will issue notes in certificated form (the “Certificated Notes”) in exchange for that global security. In addition, we may at any time and in our sole discretion decide not to have the notes represented by global securities. In such event, we will issue Certificated Notes in exchange for all of the notes represented by global securities. The Certificated Notes issued in exchange for those global securities will be in the same minimum denominations and be of the same aggregate principal amount and tenor as the portion of each global security to be exchanged. Except as provided above, owners of beneficial interests in a global security will not be entitled to receive physical delivery of Certificated Notes and will not be considered the registered holders of the notes for any purpose, including receiving payments of principal or interest.

As long as DTC or its nominee is the registered owner of the global security certificates, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the global security certificates and all notes represented by these certificates for all purposes under the instruments governing the rights and obligations of holders of such notes. Except in the limited circumstances referred to above, owners of beneficial interests in global security certificates:

All redemption proceeds, distributions and interest payments on the notes and all transfers and deliveries of such notes will be made to Cede & Co., or such other nominee, as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the issuer or its agent, on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of that participant and not of DTC, the

S-20

trustee, the issuer or any affiliate thereof, or any of their agents, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the issuer or its agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of Direct and Indirect Participants.

Ownership of beneficial interests in the global security certificates will be limited to participants or persons that may hold beneficial interests through institutions that have accounts with DTC or its nominee. Ownership of beneficial interests in global security certificates will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by DTC or its nominee, with respect to participants’ interests, or any participant, with respect to interests of persons held by the participant on their behalf. Payments, transfers, deliveries, exchanges, redemptions and other matters relating to beneficial interests in global security certificates may be subject to various policies and procedures adopted by DTC from time to time. Neither Huntington nor the trustee will have any responsibility or liability for any aspect of DTC’s or any Direct or Indirect Participant’s records relating to, or for payments made on account of, beneficial interests in global security certificates, or for maintaining, supervising or reviewing any of DTC’s records or any Direct or Indirect Participant’s records relating to these beneficial ownership interests.

Neither Huntington, nor any of the underwriters or the trustee, will have any responsibility for the performance by DTC or its Direct Participants or Indirect Participants of their respective obligations under the rules and procedures governing DTC.

The information in this section concerning DTC and its book-entry system has been obtained from sources that Huntington believes to be accurate, but we assume no responsibility for the accuracy thereof.

Clearstream and Euroclear. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Beneficial interests in the global securities representing the notes will be held in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries.

Clearstream is registered as a bank in Luxembourg, and as such is subject to regulation by the Commission de Surveillance du Secteur Financier and the Banque Centrale du Luxembourg, which supervise and oversee the activities of Luxembourg banks. Clearstream Participants are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations, and may include the underwriters or their affiliates. Indirect access to Clearstream is available to other institutions that clear through or maintain a custodial relationship with a Clearstream Participant. Clearstream has established an electronic bridge with Euroclear as the operator of the Euroclear System (the “Euroclear Operator”) in Brussels to facilitate settlement of trades between Clearstream and the Euroclear Operator.

Distributions with respect to the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

S-21

Euroclear holds securities and book-entry interests in securities for participating organizations (“Euroclear Participants”) and facilitates the clearance and settlement of securities transactions between Euroclear Participants, and between Euroclear Participants and participants of certain other securities intermediaries through electronic book-entry changes in accounts of such participants or other securities intermediaries. Euroclear provides Euroclear Participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing, and related services. Euroclear Participants are investment banks, securities brokers and dealers, banks, central banks, supranationals, custodians, investment managers, corporations, trust companies and certain other organizations, and may include the underwriters or their affiliates. Non-participants in Euroclear may hold and transfer beneficial interests in a global security through accounts with a Euroclear Participant or any other securities intermediary that holds a book-entry interest in a global security through one or more securities intermediaries standing between such other securities intermediary and Euroclear.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

Transfers between Euroclear Participants and Clearstream Participants will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Cross-market transfers between DTC’s participating organizations (“DTC Participants”), on the one hand, and Euroclear Participants or Clearstream Participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (European time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the global security in DTC, and making or receiving payment in accordance with normal procedures for same-day fund settlement applicable to DTC. Euroclear Participants and Clearstream Participants may not deliver instructions directly to their respective U.S. depositaries.

Due to time zone differences, the securities accounts of a Euroclear Participant or Clearstream Participant purchasing an interest in a global security from a DTC Participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear Participant or Clearstream Participant, during the securities settlement processing day (which must be a business day for Euroclear or Clearstream) immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of sales of interests in a global security related to the notes by or through a Euroclear Participant or Clearstream Participant to a DTC Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following the DTC’s settlement date.

S-22

The information in this section concerning Euroclear and Clearstream and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of that information.

None of us, any of the underwriters or the trustee will have any responsibility for the performance by Euroclear or Clearstream or their respective participants of their respective obligations under the rules and procedures governing their operations.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and they may discontinue the procedures at any time.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

General

The following is a general summary of certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of the notes applicable to U.S. and non-U.S. holders (as defined below) who acquire notes pursuant to this offering at their original “issue price” (the first price at which a substantial amount of the notes is sold for cash (excluding sales to bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers)). This summary is based on the Internal Revenue Code of 1986, as amended, which we refer to as the “Code,” U.S. Treasury regulations promulgated thereunder, judicial opinions, published positions of the IRS and other applicable authorities, each as in effect as of the date hereof. These authorities are subject to change or differing interpretations (possibly with retroactive effect), and any such change or interpretation could affect the accuracy of the statements and conclusions set forth herein.

This summary is for general information only and does not address all aspects of U.S. federal income taxation that may be relevant to a particular investor in light of that investor’s individual circumstances, nor does it address the effects of any state, local or non-U.S. tax laws or any U.S. federal estate, gift, generation-skipping transfer or alternative minimum tax considerations. This discussion deals only with notes held as “capital assets” within the meaning of Section 1221 of the Code, and it does not purport to be applicable to holders subject to special rules, such as banks, financial institutions, insurance companies, tax-exempt entities, grantor trusts, dealers in securities or currencies, traders in securities that elect the mark-to-market method of accounting for their securities holdings, persons subject to the alternative minimum tax, U.S. holders (as defined below) whose “functional currency” is not the U.S. dollar, entities classified as partnerships for U.S. federal income tax purposes or other flow-through entities or arrangements (and investors therein), subchapter S corporations, retirement plans, individual retirement accounts or other tax-deferred accounts, controlled foreign corporations, real estate investment trusts, regulated investment companies or passive foreign investment companies for U.S. federal income tax purposes, certain former citizens or long-term residents of the United States subject to U.S. federal income tax as expatriates, persons holding the notes through a “hybrid entity” or persons holding the notes as a hedge against currency risks, as a position in a “straddle” or as part of a “wash sale,” “hedging,” “conversion,” “constructive sale” or “integrated” transaction for U.S. federal income tax purposes and persons required to accelerate the recognition of any item of gross income with respect to the notes as a result of such income being recognized on an applicable financial statement. This summary does not address the tax considerations that may be relevant to subsequent purchasers of the notes and does not address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010 nor any considerations with respect to any withholding required pursuant to the Foreign Account Tax Compliance Act of 2010 (including the Treasury regulations promulgated thereunder and intergovernmental agreements entered in connection therewith). This discussion assumes that the notes will be treated as debt instruments for U.S. federal income tax purposes.

If a partnership or an entity treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner in the partnership or an equity interest owner of such other entity will generally depend upon the status of the person and the activities of the partnership or other entity treated as a partnership. Thus, persons who are partners in a partnership or equity interest owners of another entity treated as a partnership holding any of the notes should consult their own tax advisors. We have not sought and will not seek any ruling from the IRS with respect to the statements made and the conclusions reached in this discussion, and there can be no assurance that the IRS will agree with such statements and conclusions.

Under certain circumstances, we will be discharged from any and all obligations in respect of the indenture. Such discharge may be treated as a taxable exchange for U.S. federal income tax purposes. Holders should consult their own tax advisors regarding the U.S. federal, state, and local tax consequences of such a discharge.

S-24

THIS SUMMARY OF U.S. FEDERAL INCOME TAX ISSUES IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSIDERATIONS FOR U.S. AND NON-U.S. HOLDERS RELATING TO THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES. PROSPECTIVE HOLDERS SHOULD CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL, FOREIGN INCOME, ESTATE AND OTHER TAX LAWS OR ANY TAX TREATY.

U.S. Holders of the Notes

As used in this discussion, the term “U.S. holder” means a holder that is a beneficial owner of a note and that is, for U.S. federal income tax purposes:

Interest on the Notes. It is expected, and this discussion assumes, that the notes will be issued with less than a statutorily defined de minimis amount of original issue discount for U.S. federal income tax purposes. Accordingly, a U.S. holder will generally be required to recognize as ordinary income any interest paid or accrued on the notes in accordance with its regular method of accounting for U.S. federal income tax purposes.

Disposition of Notes. Upon the sale, exchange, redemption, retirement or other taxable disposition of a note, a U.S. holder generally will recognize taxable gain or loss equal to the difference, if any, between the amount realized on the sale, exchange, redemption, retirement or other taxable disposition (except to the extent of accrued but unpaid interest, which will be taxable as ordinary income) and such holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note generally will be equal to the amount that such U.S. holder paid for the note. Any such gain or loss will be capital gain or loss, and will be long-term capital gain or loss if at the time of the disposition a U.S. holder has held the note for more than one year. Long-term capital gains of noncorporate U.S. holders are generally subject to tax at preferential rates. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding. Information reporting requirements generally will apply in connection with payments of interest on the notes to, and the proceeds from a sale, exchange or other disposition of the notes by, noncorporate U.S. holders. Under the Code and applicable U.S. Treasury regulations, a U.S. holder may be subject to backup withholding (currently at a rate of 24% for payments made before January 1, 2026) with respect to any payments on the notes, or the proceeds of a sale, exchange or other disposition of the notes, unless such U.S. holder (a) comes within certain exempt categories and, when required, demonstrates this fact in the manner required, or (b) within a reasonable period of time, provides a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. holder will generally be allowed as a credit against such U.S. holder’s U.S. federal income tax liability and may entitle such U.S. holder to a refund, provided that the required information is timely furnished to the IRS.

S-25

Non-U.S. Holders of the Notes

As used in this discussion, the term “non-U.S. holder” means a beneficial owner of a note that is not, for U.S. federal income tax purposes, a U.S. holder as defined above, nor an entity or arrangement that is treated as a partnership for U.S. federal income tax purposes.

Interest on the Notes. Subject to the discussions below under “—Backup Withholding, Information Reporting and Other Reporting Requirements,” U.S. federal withholding tax will not apply to any payment of interest on a note to a non-U.S. holder if the interest qualifies for the “portfolio interest exemption.” This will be the case provided that the non-U.S. holder:

Special certification and other rules apply to certain non-U.S. holders that are entities rather than individuals, particularly entities treated as partnerships for U.S. federal income tax purposes and certain other flow through entities, and to non-U.S. holders acting as (or holding notes through) intermediaries.

If the portfolio interest exemption does not apply, payments of interest will be subject to U.S. federal withholding tax at a 30% tax rate, unless the non-U.S. holder provides us with a properly executed: (1) IRS Form W-8BEN, W-8BEN-E or other appropriate form, claiming an exemption from or reduction in withholding under the benefit of an income tax treaty or (2) IRS Form W-8ECI, or successor form, stating that interest paid on the note is not subject to withholding tax because it is effectively connected with its conduct of a trade or business in the United States.

If a non-U.S. holder is engaged in a trade or business in the United States and interest on a note is effectively connected with the conduct of that trade or business (and, if required under an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by the non-U.S. holder), such non-U.S. holder (although exempt from U.S. federal withholding tax at the 30% tax rate) will be subject to U.S. federal income tax on that interest on a net income basis in the same manner as if the non-U.S. holder were a U.S. holder. In addition, if such non-U.S. holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% of “effectively connected earnings and profits,” as determined under the Code, for the taxable year. However, any branch profits tax that would otherwise apply may not apply, or may apply at a reduced rate, under an applicable income tax treaty.

Disposition of Notes. Subject to the discussions below under “—Backup Withholding, Information Reporting and Other Reporting Requirements,” except with respect to accrued and unpaid interest, which will be treated as described above under “—Non-U.S. Holders of the Notes—Interest on the Notes,” any gain realized on the sale, exchange, redemption, retirement or other taxable disposition of a note by a non-U.S. holder generally will not be subject to U.S. federal income tax unless: (i) that gain is effectively connected with the conduct of a trade or business in the United States by the non-U.S. holder (and, if required under an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by the non-U.S. holder), in which case such person will be subject to U.S. federal income tax on a net income basis at the regular graduated U.S. federal

S-26

income tax rates in the same manner as if such non-U.S. holder were a U.S. person, and if such non-U.S. holder is a corporation, such holder may be subject to the branch profits tax referred to above, unless the holder qualifies for a lower rate or an exemption from such branch profits tax under an applicable income tax treaty, or (ii) such person is an individual who is present in the United States for 183 days or more in the taxable year of that disposition and other conditions are met in which case such person will generally be subject to a U.S. federal income tax of 30% (or, if applicable, a lower income tax treaty rate) on such gain, which may be offset by U.S. source capital losses, if any, of the non-U.S. holder.

Backup Withholding, Information Reporting and Other Reporting Requirements. In general, backup withholding will not apply to a payment of interest on a note to a non-U.S. holder, or to proceeds from the disposition of a note by a non-U.S. holder, in each case, if the holder certifies under penalties of perjury that it is not a U.S. person as defined under the Code and neither we nor our paying agent has actual knowledge to the contrary.

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale or other disposition of notes by a non-U.S. holder outside the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States unless the proceeds are transferred to an account maintained by the non-U.S. holder in the United States, the payment of proceeds or the confirmation of the sale is mailed to the non-U.S. holder at a United States address or the sale has some other specified connection to the United States. However, if a non-U.S. holder sells or otherwise disposes of notes through a U.S. broker or the U.S. offices of a foreign broker, the broker will generally be required to report the amount of proceeds paid to the non-U.S. holder to the IRS and also to backup withhold on that amount unless such non-U.S. holder provides appropriate certification to the broker of its status as a non-U.S. person or otherwise establishes an exemption (and the payor does not have actual knowledge or reason to know that such holder is a U.S. person as defined under the Code). Information reporting will also apply if a non-U.S. holder sells notes through a foreign broker which derives more than a specified percentage of its income from U.S. sources or having certain other connections to the United States, unless such broker has documentary evidence in its records that such non-U.S. holder is a non-U.S. person and certain other conditions are met, or such non-U.S. holder otherwise establishes an exemption (and the payor does not have actual knowledge or reason to know that such holder is a U.S. person as defined under the Code).

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder generally can be credited against the non-U.S. holder’s U.S. federal income tax liability, if any, or refunded, provided that the required information is furnished to the IRS in a timely manner. Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

THE FOREGOING SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO INVESTORS IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES AND INCOME TAX SITUATION. INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES THAT WOULD RESULT FROM THEIR PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

S-27

CERTAIN ERISA CONSIDERATIONS

Each person considering the use of plan assets of a pension, profit-sharing or other employee benefit plan, individual retirement account (“IRA”), Keogh plan or other retirement plan, account or arrangement, or a “plan,” to acquire or hold the notes should consider whether an investment in the notes would be consistent with the documents and instruments governing the plan and with its fiduciary duties, including satisfaction of applicable prudence and diversification requirements. Such persons should also consider whether an investment in the notes would involve a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or Section 4975 of the Code.

Section 406 of ERISA and Section 4975 of the Code, as applicable, prohibit plans subject to Title I of ERISA and/or Section 4975 of the Code, including entities such as collective investment funds, partnerships and separate accounts or insurance company pooled separate accounts or insurance company general accounts whose underlying assets include the assets of such plans (collectively, “Plans”) from engaging in certain transactions involving “plan assets” with persons who are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to such Plans. Such parties in interest or disqualified persons could include, without limitation, Huntington, the underwriters, the trustee or any of their respective affiliates. A violation of these prohibited transaction rules may result in civil penalties or other liabilities under ERISA and/or an excise tax under Section 4975 of the Code for those persons, unless exemptive relief is available under an applicable statutory, regulatory or administrative exemption. Certain plans including those that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) are not subject to the requirements of ERISA or Section 4975 of the Code, but may be subject to similar provisions under applicable federal, state, local or non-U.S. or other laws, rules or regulations (“Similar Laws”).

The acquisition or holding of the notes by or on behalf of a Plan with respect to which we or certain of our affiliates are or become a party in interest or a disqualified person may constitute or result in prohibited transactions under ERISA or Section 4975 of the Code, unless the notes are acquired or held pursuant to and in accordance with an applicable exemption.

Certain prohibited transaction class exemptions (“PTCEs”) issued by the U.S. Department of Labor may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the notes. These class exemptions include: PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of the notes and related lending transactions, provided that neither the Issuer of the notes nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of the Plan involved in the transaction and provided, further, that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction. There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the notes.

Each purchaser or holder of the notes or any interest therein, and each person making the decision to purchase or hold the notes on behalf of any such purchaser or holder, will be deemed by its acquisition of the notes to have represented and warranted in both its individual capacity and its representative capacity (if any), that on each day from the date on which the purchaser or holder acquires its interest in the notes to the date on which the purchaser disposes of its interest in the notes, either (i) such purchaser and holder is not acquiring or holding the notes with “plan assets” of any Plan or the assets of any governmental plan, church plan or non-U.S. plan, or (ii) (A) its purchase and holding of the notes will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation of any Similar Laws, and (B) neither

S-28

Huntington nor any of our affiliates is acting as a fiduciary (within the meaning of Section 3(21) of ERISA or within the meaning of any Similar Laws) in connection with the purchase or holding of the notes and has not provided any advice concerning the purchase or holding of the notes.

Further, if the purchaser is a Plan or the purchase is made on behalf of or with “plan assets” of a Plan, such purchaser will be deemed to have represented and warranted that (1) none of the underwriters, Huntington, the trustee and their respective affiliates (collectively with the underwriters and Huntington, the “Transaction Parties”) has acted as the Plan’s fiduciary (within the meaning of ERISA or the Code), or has been relied upon for any advice, with respect to the purchaser’s decision to acquire and hold the notes, and none of the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the notes, and (2) the decision to purchase a note has been made by a duly authorized fiduciary of the Plan that (i) is independent (as that term is used in 29 C.F.R. § 2510.3-21(c)(1)) of the Transaction Parties and there is no financial interest, ownership interest or other relationship, agreement or understanding or otherwise that would limit its ability to carry out its fiduciary responsibility to the Plan; (ii) is a bank, insurance carrier, registered investment adviser, a registered broker-dealer, or an independent fiduciary that holds, or has under management or control, total assets of at least $50 million (in each case, as specified in 29 C.F.R. § 2510.3-21(c)(1)(i)(A)-(E)); (iii) in the case of a Plan that is an IRA, is not the IRA owner, beneficiary of the IRA or relative of the IRA owner or beneficiary; (iv) is capable of evaluating investment risks independently, both in general and with regard to particular transactions and investment strategies (including, without limitation, with respect to the decision to invest in the note); (v) has been fairly informed that the Transaction Parties have not and will not undertake to provide impartial investment advice, or to give advice in a fiduciary capacity, in connection with the purchase and holding of the note; (vi) has been fairly informed that the Transaction Parties have financial interests in the Plan’s purchase and holding of a note, which interests may conflict with the interest of the Plan, as more fully described in this prospectus supplement, including the section entitled “Underwriting (Conflicts of Interest)”; (vii) is a fiduciary under ERISA or the Code, or both, with respect to the decision to purchase and hold a note and is responsible for exercising (and has exercised) independent judgment in evaluating whether to invest the assets of such Plan in the note; and (viii) is not paying any Transaction Party, any fee or other compensation directly for the provision of investment advice (as opposed to other services) in connection with the Plan’s purchase and holding of a note. The representations in this paragraph are intended to comply with 29 C.F.R. § 2510.3-21(a) and (c)(1) as promulgated on April 8, 2016 (81 Fed. Reg. 20,997). To the extent these regulations are revoked, repealed or no longer effective, the representations in this paragraph shall be deemed to be no longer in effect. None of the Transaction Parties is undertaking to provide impartial investment advice, or to give advice in a fiduciary capacity, in connection with the purchase of the notes by any Plan.

The foregoing discussion is general in nature and is not intended to be all inclusive. Each Plan fiduciary (and each fiduciary for governmental, church or foreign plans subject to Similar Laws) should consult with its legal advisor concerning the potential consequences to the plan under ERISA, Section 4975 of the Code or such Similar Laws of an investment in the notes.

S-29

UNDERWRITING (CONFLICTS OF INTEREST)

Morgan Stanley & Co. LLC, Goldman Sachs & Co. LLC, and RBC Capital Markets, LLC are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in a firm commitment underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the several underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Underwriting Discount

The representatives have advised us that the underwriters propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of 0.25% of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may re-allow, a concession of up to 0.125% of the principal amount of the notes to certain other dealers. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discount, will be approximately $1,292,250.

New Issue of Notes

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the

S-30

notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

Price Stabilization and Short Positions

In connection with the offering, the underwriters may purchase and sell the notes in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater principal amount of notes than they are required to purchase in the offering. The underwriters must close out any short position by purchasing notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions may be effected in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

In connection with the offering of the notes, the person (if any) named as the stabilizing manager(s) (or persons acting on their behalf) may over-allot notes or effect transactions with a view to supporting the market price of the notes at a level higher than that which might otherwise prevail. However, there is no assurance that the stabilizing managers (or persons acting on their behalf) will undertake stabilization action. Any stabilization action may begin on or after the date of adequate public disclosure of the terms of the offer of the relevant notes is made and, if begun, may be ended at any time, but it must end no later than 30 days after the date on which the issuer received the proceeds of the issue or no later than 60 days after the date of allotment of the relevant notes, whichever is the earlier.

Conflicts of Interest

Our affiliate, The Huntington Investment Company, is a member of FINRA and is participating in the distribution of the notes. The distribution arrangements for this offering comply with the requirements of FINRA Rule 5121, regarding a FINRA member firm’s participation in the distribution of securities of an affiliate. In accordance with that rule, no FINRA member firm that has a “conflict of interest,” as defined therein, may make sales in this offering to any discretionary account without the prior approval of the customer.

Our affiliates, including The Huntington Investment Company, may use this prospectus supplement and the accompanying prospectus in connection with offers and sales of the notes in the secondary market. These affiliates may act as principal or agent in those transactions. Secondary market sales will be made at prices related to market prices at the time of sale.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities.

S-31

Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. Additionally, certain of the underwriters are acting as initial purchasers in connection with the concurrent offering of notes by The Huntington National Bank, for which they will receive customary compensation from The Huntington National Bank.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of us (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters may hedge, their credit exposure to us consistent with their customary risk management policies.

Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend.

Selling Restrictions

Canada

The notes may be sold in Canada only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional

S-32

client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPS Regulation.

United Kingdom

Each underwriter has represented, warranted and agreed that,

(a) it has complied and will comply with all applicable provisions of the Financial Services and Markets Act 2000 (“FSMA”) with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom; and

(b) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue and sale of such notes in circumstances in which Section 21(1) of the FSMA does not apply to us.

This document is for distribution only to persons who (i) have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Financial Promotion Order”), (ii) are persons falling within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc”) of the Financial Promotion Order, (iii) are outside the United Kingdom, or (iv) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) in connection with the issue or sale of any securities may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as “relevant persons”). This document is directed only at relevant persons and must not be acted on or relied on by persons who are not relevant persons. Any investment or investment activity to which this document relates is available only to relevant persons and will be engaged in only with relevant persons.

Japan

The securities have not been and will not be registered under the Financial Instruments and Exchange Law of Japan (Law No. 25 of 1948 of Japan, as amended, “the FIEL”). Each underwriter has represented and agreed that it has not offered or sold, and will not offer or sell, any securities, directly or indirectly, in Japan or to, or for the benefit of, any Japanese person or to others, for re-offering or resale, directly or indirectly, in Japan or to a Japanese person, except for persons who are “qualified institutional investors” as defined in the Cabinet Ordinance Concerning Definitions under Article 2 of the Financial Instruments and Exchange Law of Japan (Ordinance No. 14 of 1993 of the Ministry of Finance of Japan, as amended) or otherwise in compliance with the FIEL and other applicable laws, regulations and governmental guidelines in Japan. For purposes of this paragraph, “Japanese person” means any person resident in Japan, including any corporation or other entity organized under the laws of Japan.

Hong Kong

Each underwriter has represented and agreed that (a) it has not offered or sold and will not offer or sell in Hong Kong any notes by means of any document other than (i) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571) of Hong Kong (“SFO”) and any rules made thereunder or (ii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies (Winding up and Miscellaneous Provisions) Ordinance (Cap. 32) of Hong Kong, or which do not constitute an offer to the public within the meaning of that Ordinance and (b) it has not issued or had in its possession for the purposes of issue, and will not have in its possession for the purpose of issue, whether in Hong

S-33

Kong or elsewhere, any advertisement, invitation or document relating to the notes, which is directed at, or the contents of which are likely to be accessed or read by, the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the SFO and any rules made thereunder.

RISK FACTORS

Prior to making any investment decision with respect to the securities that we may offer, prospective investors should carefully consider the specific factors set forth under the caption “Risk Factors” in the applicable prospectus supplement and in our periodic reports filed with the U.S. Securities and Exchange Commission (the “SEC”) that are incorporated by reference herein, together with all of the other information appearing in this prospectus or in the applicable prospectus supplement or incorporated by reference into this prospectus in light of their particular investment objectives and financial circumstances.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC using a “shelf” registration or continuous offering process. Under this shelf process, we or one or more selling security holders to be identified in the future may from time to time sell any combination of the securities described in this prospectus in one or more offerings.

The following securities may be offered from time to time:

This prospectus provides you with a general description of the securities that we or any selling security holder may offer as well as other information you should know before investing in our securities. Each time that we or any selling security holder offer securities, we will file with the SEC a prospectus supplement containing specific information about the terms of the securities being offered. The prospectus supplement may include a discussion of any risk factors or other special considerations that apply to those securities. The prospectus supplement may also add, update, or change the information in this prospectus. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement, you should rely on the information in that prospectus supplement. You should read both this prospectus and the applicable prospectus supplement together with additional information described under the headings “Where You Can Find More Information” and “Information Incorporated by Reference.”

We do not, and the underwriters and their affiliates and agents do not, take any responsibility for, and can provide no assurance as to the reliability of, information that others may provide you.

You should not assume that the information in this prospectus or the applicable prospectus supplement is accurate as of any date other than the dates on the front of those documents.

The Issuer may sell securities to underwriters who will sell the securities to the public on terms fixed at the time of sale. In addition, the securities may be sold by the Issuer directly or through dealers or agents designated from time to time. If the Issuer, directly or through agents, solicits offers to purchase the securities, the Issuer reserves the sole right to accept and, together with its agents, to reject, in whole or in part, any of those offers.

The prospectus supplement will contain the names of the underwriters, dealers, or agents, if any, together with the terms of offering, the compensation of those underwriters, dealers, or agents, and the net proceeds to us. Any underwriters, dealers, or agents participating in the offering may be deemed “underwriters” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).

One or more of our subsidiaries, including The Huntington Investment Company, may buy and sell any of the securities after the securities are issued as part of their business as a broker-dealer. Those subsidiaries may use this prospectus and the related prospectus supplement in those transactions. Any sale by a subsidiary will be made at the prevailing market price at the time of sale.

EXPLANATORY NOTE

Retrospective Presentation for Change in Accounting Principle

Effective for 2016, we adopted Accounting Standards Update (ASU) 2015-03, Imputation of Interest (Topic 835): Simplifying the Presentation of Debt Issuance Costs. The ASU was issued to simplify the presentation of debt issuance costs. The amendments require debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction to the carrying amount of that debt liability, consistent with debt discounts. Amounts reclassified in the prior periods were immaterial to Huntington’s Unaudited Condensed Consolidated Financial Statements.

FORWARD-LOOKING STATEMENTS

This prospectus and any accompanying prospectus supplement contain or incorporate by reference forward-looking statements about the Issuer that are intended to be subject to the safe harbors created under U.S. federal securities laws. The use of words such as “anticipates,” “estimates,” “expects,” “intends,” “plans” and “believes,” among others, generally identify forward-looking statements; however, these words are not the exclusive means of identifying such statements. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts.

By their nature, forward-looking statements are subject to numerous assumptions, risks, and uncertainties. A number of factors could cause actual conditions, events, or results to differ significantly from those described in the forward-looking statements. These factors include, but are not limited to, those which may be set forth in the accompanying prospectus supplement and those under the heading “Risk Factors” included in our Annual Reports on Form 10-K, and other factors described in our periodic reports filed from time to time with the SEC. Actual results, performance or achievement could differ materially from those contained in these forward-looking statements for a variety of reasons, including, without limitation, those discussed under “Risk Factors” in the applicable prospectus supplement and in other information contained in our publicly available filings with the SEC. Other unknown or unpredictable factors also could have a material adverse effect on us and our business, financial condition and results of operations.

We encourage you to understand forward-looking statements to be strategic objectives rather than absolute forecasts of future performance. Forward-looking statements speak only as of the date they are made, and are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. We are not under any obligation to, or intend to, publicly update or review any of these forward-looking statements, whether as a result of new information, future events or otherwise, even if experience or future events make it clear that any expected results expressed or implied by those forward-looking statements will not be realized. Please carefully review and consider the various disclosures made in the applicable prospectus supplement and in our other reports filed with the SEC that attempt to advise interested parties of the risks and factors that may affect our business, results of operations, financial condition or prospects.
