#### <br>

#### Huntington Bancshares Incorporated

#### $1,000,000,000 4.623% Fixed-to-Floating Rate Senior Notes due 2032<br>

#### $750,000,000 5.605% Fixed-to-Fixed Rate Subordinated Notes due 2041
We are offering $1,000,000,000 aggregate principal amount of our 4.623% fixed-to-floating rate senior notes due January 28, 2032 (the "senior notes") and $750,000,000 aggregate principal amount of our 5.605% fixed-to-fixed rate subordinated notes due January 28, 2041 (the "subordinated notes" and, together with the senior notes, the "notes").

The senior notes will mature on January 28, 2032 (the "senior notes Maturity Date"). The senior notes will accrue interest from (and including) January 28, 2026 (the "senior notes Issue Date") to (but excluding) January 28, 2031 at a fixed rate of 4.623% per annum, and from (and including) January 28, 2031 to (but excluding) the senior notes Maturity Date at a floating rate equal to a benchmark rate based on the Compounded SOFR Index Rate (as defined in "Description of Notes—Senior Notes—Calculation of the Benchmark") plus 99.0 basis points per annum.

The subordinated notes will mature on January 28, 2041 (the "subordinated notes Maturity Date" and, together with the senior notes Maturity Date, each, a "Maturity Date"). The subordinated notes will accrue interest from (and including) January 28, 2026 (the "subordinated notes Issue Date") to (but excluding) January 28, 2036 (the "subordinated notes Reset Date") at a fixed rate of 5.605% per annum, and from (and including) the subordinated notes Reset Date to (but excluding) the subordinated notes Maturity Date at a rate per annum which will be the Five-year U.S. Treasury Rate (as defined herein) as of the subordinated notes Reset Determination Date (as defined herein) plus 1.350% per annum.

We have the option to redeem the senior notes, at the applicable times and at the applicable redemption price set forth under "Description of Notes—Senior Notes—Optional Redemption," and we have the option to redeem the subordinated notes, at the applicable times and at the applicable redemption price set forth under "Description of Notes—Subordinated Notes—Optional Redemption." Holders of any notes redeemed will also receive accrued and unpaid interest thereon to (but excluding) the applicable date of 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. See "Description of Notes—Senior Notes—Optional Redemption" and "Description of Notes—Subordinated Notes—Optional Redemption" in this prospectus supplement.

The senior notes will be unsecured and unsubordinated obligations of Huntington Bancshares Incorporated, a Maryland corporation, and will rank equally with all of our other unsecured and unsubordinated indebtedness. The subordinated notes will be unsecured and subordinated in right of payment to the payment of our existing and future Senior Debt (as defined herein), will rank equal in right of payment to all of our existing and future indebtedness ranking on a parity with the subordinated notes and will be senior to any liabilities and other obligations of ours that rank junior and not equally with or prior to the subordinated notes. The notes will not be guaranteed by any of our subsidiaries. See "Description of Notes" in this prospectus supplement.

The notes will be issued only in registered book-entry form, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The notes will not be listed on any securities exchange. Currently there is no public market for the notes.

**Investing in the notes involves risks.

#### **TABLE OF CONTENTS**

#### 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, estimates, and uncertainties that are beyond the control of Huntington. 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, continue, believe, intend, estimate, plan, trend, objective, 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, Section 21E of the Securities Exchange Act of 1934, and the Private Securities Litigation Reform Act of 1995.

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 or historical performance: changes in general economic, political, regulatory or industry conditions; deterioration in business and economic conditions, including persistent inflation, supply chain issues or labor shortages, instability in global economic conditions and geopolitical matters, as well as volatility in financial markets; changes in U.S. trade policies, including the imposition of tariffs and retaliatory tariffs; the impact of pandemics and other catastrophic events or disasters on the global economy and financial market conditions and our business, results of operations, and financial condition; the impacts related to or resulting from bank failures and other volatility, including potential increased regulatory requirements and costs, such as Federal Deposit Insurance Corporation (the "FDIC") special assessments, long-term debt requirements and heightened capital requirements; potential impacts to macroeconomic conditions, which could affect the ability of depository institutions, including us, to attract and retain depositors and to borrow or raise capital; unexpected outflows of uninsured deposits which may require us to sell investment securities at a loss; changing interest rates which could negatively impact the value of our portfolio of investment securities; the loss of value of our investment portfolio which could negatively impact market perceptions of us and could lead to deposit withdrawals; the effects of social media on market perceptions of us and banks generally; cybersecurity risks; uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Board of Governors of the Federal Reserve System (the "Federal Reserve"); volatility and disruptions in global capital, foreign exchange 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, including those implementing our "Fair Play" banking philosophy; introduction of new competitive products, such as stablecoins, and new competitors such as financial technology companies and other "nontraditional" bank competitors; changes in policies and standards for regulatory review of bank mergers; 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 Securities and Exchange Commission (the "SEC"), the Office of the Comptroller of the Currency, the Federal Reserve, the FDIC, the Consumer Financial Protection Bureau and state-level regulators; the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the Merger Agreement between Huntington and Cadence (each as defined herein); the outcome of any legal proceedings that may be instituted against Huntington or Cadence; delays in completing the proposed transaction involving Huntington and Cadence; the failure to satisfy any of the conditions to the Cadence Merger (as defined herein) on a timely basis or at all; the possibility that the anticipated benefits of recent or proposed acquisitions are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of Huntington and Cadence or as a result of the strength of the economy and competitive factors in the areas where Huntington and Cadence do business; the possibility that the Cadence Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the ability of Huntington and Cadence to meet expectations regarding the timing, completion and accounting and tax treatment of the Cadence Merger; diversion of management's attention from ongoing business operations and opportunities; potential adverse reactions or changes to business, customer or employee relationships, including those resulting from the announcement or completion of the Cadence Merger; the ability to complete the Cadence Merger and integration of Huntington and Cadence successfully; the dilution caused by Huntington's issuance of additional shares of its capital stock in connection with the transaction; and other factors that may affect the future results of Huntington.

#### **TABLE OF CONTENTS**
All forward-looking statements are expressly qualified in their entirety by the cautionary statements set forth above. Forward-looking statements speak only as of the date they are made and are based on information available at that time. Huntington does not assume any obligation to update forward-looking statements to reflect actual results, new information or future events, changes in assumptions or changes in circumstances or other factors affecting forward-looking statements 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. If Huntington updates one or more forward-looking statements, no inference should be drawn that Huntington will make additional updates with respect to those or other forward-looking statements. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements.

Additional factors that could cause results to differ materially from those described above can be found in our Annual Report on Form 10-K for the year ended December 31, 2024 and in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025, and September 30, 2025 and the 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 Huntington's Annual Report on Form 10-K for the year ended December 31, 2024 and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025 and September 30, 2025, as filed with the SEC and available on its website at www.sec.gov, and in this prospectus supplement and the accompanying prospectus.

#### SUMMARY OF THE SENIOR NOTES OFFERING
*The following summary contains basic information about the senior notes and this offering and is not intended to be complete. It does not contain all the information that you should consider before deciding whether to invest in the senior notes. For a complete understanding of the senior notes, you should read the section of this prospectus supplement titled "Description of Notes—Senior Notes."* 

#### Issuer
Huntington Bancshares Incorporated, a Maryland corporation and a financial holding company.

#### Notes Offered
$1,000,000,000 aggregate principal amount of 4.623% Fixed-to-Floating Rate Senior Notes due 2032 (the "senior notes").

#### Issue Date
January 28, 2026 (the "senior notes Issue Date").

#### Maturity Date
The senior notes will mature on January 28, 2032 (the "senior notes Maturity Date"), unless the senior notes are prior redeemed in whole or in part as described below under "Description of Notes—Senior Notes—Optional Redemption."

#### Interest Rate
From (and including) the senior notes Issue Date to (but excluding) January 28, 2031 (the "Fixed Rate Period"), the interest on the senior notes will be payable at a rate of 4.623% per annum (the "Initial Interest Rate").

From (and including) January 28, 2031 to (but excluding) the senior notes Maturity Date (the "Floating Rate Period"), the interest rate on the senior notes will be equal to a benchmark rate based on the Compounded SOFR Index Rate plus 99.0 basis points per annum, as further described below.

*<u>Fixed Rate Period</u>*

Interest during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months.

*<u>Floating Rate Period</u>*

The interest rate on the senior notes during the Floating Rate Period will be calculated quarterly on each Interest Determination Date (as defined below). In no event will the interest payable on the senior notes be less than zero. Interest will be computed on the basis of the actual number of days in each Floating Rate Interest Period (as defined below) and a 360-day year. The amount of accrued interest payable on the senior notes for each Floating Rate Interest Period will be computed by multiplying (i) the outstanding principal amount of the senior notes by (ii) the product of (a) the interest rate for the relevant Floating Rate Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Floating Rate Interest Period relating to such Floating Rate Interest Period divided by 360.

#### Interest Payment Dates
*<u>Fixed Rate Period</u>*

The senior notes will accrue interest and we will pay interest semi-annually on each January 28 and July 28, commencing on July 28, 2026, and ending on January 28, 2031 (each, a "Fixed Rate Period Interest Payment Date").

If any scheduled Fixed Rate Period Interest Payment Date is not a Business Day, any payment of principal and interest will be postponed to the next day that is a Business Day, but interest on that payment will not accrue during the period from and after the scheduled Fixed Rate Period Interest Payment Date.

*<u>Floating Rate Period</u>*

Interest will be payable quarterly on April 28, 2031, July 28, 2031, October 28, 2031 and on the senior notes Maturity Date (each, a "Floating Rate Period Interest Payment Date").

S-3<br>

------

#### **TABLE OF CONTENTS**
If any scheduled Floating Rate Period Interest Payment Date (other than the senior notes Maturity Date) is not a Business Day, such Floating Rate Period Interest Payment Date will be postponed to the next day that is a Business Day; provided that if that Business Day falls in the next succeeding calendar month, such Floating Rate Period Interest Payment Date will be the immediately preceding Business Day. If any such Floating Rate Period Interest Payment Date (other than the senior notes Maturity Date) is postponed or brought forward as described above, the payment of interest due on such postponed or brought forward Floating Rate Period Interest Payment Date will include interest accrued to but excluding such postponed or brought forward Floating Rate Period Interest Payment Date.

#### Floating Rate Interest Period
During any Floating Rate Period, the period from (and including) a Floating Rate Period Interest Payment Date and ending on (but excluding) the next succeeding Floating Rate Period Interest Payment Date or the senior notes Maturity Date (each, a "Floating Rate Interest Period"); provided that the first Floating Rate Interest Period will begin on (and include) January 28, 2031 and will end on (but exclude) the first Floating Rate Period Interest Payment Date.

#### Interest Determination Date
The second U.S. Government Securities Business Day preceding the applicable Floating Rate Period Interest Payment Date, except as described herein (each, an "Interest Determination Date").

#### Record Date
The fifteenth calendar day (whether or not a Business Day) preceding the related Interest Payment Date.

#### No Guarantees
The senior notes are not guaranteed by any of our subsidiaries. As a result, the senior notes will be structurally subordinated to the liabilities of our subsidiaries as discussed below under "Description of Notes—Senior Notes—Ranking."

#### Ranking
The senior notes will be unsecured and unsubordinated obligations, 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. As of September 30, 2025, our subsidiaries had, in the aggregate, outstanding debt and other liabilities, including deposits, of approximately $187 billion. All of such debt and other liabilities would rank structurally senior to the senior notes in case of liquidation or otherwise. As of September 30, 2025, Huntington Bancshares Incorporated (parent company only) had approximately $6 billion of outstanding senior debt and approximately $1 billion of outstanding subordinated and junior subordinated debt.

The indenture pursuant to which we will issue the senior notes does not limit the amount of additional indebtedness we or our subsidiaries may incur.

#### Optional Redemption
On or after July 27, 2026 (180 days after the senior notes Issue Date) (or, if additional senior notes are issued, beginning 180 days after the issue date of such additional notes), and prior to January 28, 2031 (one year prior to the senior notes Maturity Date) (the "senior notes First Par Call Date"), we may redeem the senior notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)<br> (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the senior notes matured on the senior notes First Par Call

(2) 100% of the principal amount of the senior notes to be redeemed, 

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On the senior notes First Par Call Date, we may redeem the senior notes, in whole but not in part, or on or after December 28, 2031 (one month prior to the senior notes Maturity Date), in whole or in part, at any time and from time to time, in each case at a redemption price equal to 100% of the principal amount of the senior notes being redeemed plus accrued and unpaid interest thereon to the redemption date. See "Description of Notes—Senior Notes—Optional Redemption."

There is no sinking fund for the senior notes.

#### Further Issuance

#### **TABLE OF CONTENTS**

#### 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, 2024 and in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025, June 30, 2025, and September 30, 2025, 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.* 

#### Risks Related to the Offering

#### 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 September 30, 2025, the aggregate amount of all debt and other liabilities of our subsidiaries, including deposits, was approximately $187 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 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 indentures 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 indentures 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

S-10<br>

------

#### **TABLE OF CONTENTS**
to time, additional debt and other liabilities. In addition, we are not restricted under the indentures from granting security interests over our assets, except to the extent described under "Description of Notes—Senior Notes—Merger, Consolidation or Sale of Assets," "Description of Notes—Subordinated Notes—Merger, Consolidation or Sale of Assets," "Description of Notes—Senior Notes—Certain Covenants" and "Description of Notes—Subordinated 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 indentures. You are not protected under the indentures 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—Senior Notes—Merger, Consolidation or Sale of Assets," "Description of Notes—Subordinated Notes—Merger, Consolidation or Sale of Assets," "Description of Notes—Senior Notes—Certain Covenants" and "Description of Notes—Subordinated Notes—Certain Covenants" included in this prospectus supplement.

#### The notes are not insured or guaranteed by the FDIC or other governmental agency.
The notes are not savings accounts, deposits or other obligations of a bank and are not insured or guaranteed by the FDIC or any other governmental agency or instrumentality or any other person.

#### 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.

***We may choose to redeem the notes prior to the applicable Maturity Date, but investors should not expect us to redeem the notes on the date the notes become redeemable or on any particular date after the notes become redeemable.***

The notes have no mandatory redemption date, other than on the applicable Maturity Date, and are not redeemable at the option of investors. By their terms, the notes may be redeemed by us at our option as described below under "Description of Notes—Senior Notes—Optional Redemption" and "Description of Notes—Subordinated Notes—Optional Redemption." Any decision we may make at any time to propose a redemption will depend upon, among other things, our evaluation of our capital position, the composition of our stockholders' equity and general market conditions at that time. Although the notes contain provisions designed to compensate you for the lost value of such notes if we redeem some or all of such notes prior to the applicable Maturity Date or the applicable par call date, such provisions only approximate this lost value and may not adequately compensate you. Furthermore, depending on prevailing interest rates at the time of any such redemption,

#### **TABLE OF CONTENTS**
you may not be able to reinvest the redemption proceeds in a comparable security (including with comparable ratings) at an interest rate as high as the interest rate of the notes being redeemed or at an interest rate that would otherwise compensate you for any lost value as a result of any redemption of notes.

#### The interest rate on the senior notes will reset from fixed to floating rates.
The interest rate on the senior notes will initially be a fixed-rate of interest per annum. However, the interest rates during the respective Floating Rate Periods will be reset on the respective Interest Determination Date such that the applicable per annum interest rate will be equal to the Benchmark (as defined under "Description of Notes") plus the relevant spread. As a result, the interest rate in the Floating Rate Periods may be less than the initial interest rates and/or the interest rate that applies immediately prior to the relevant Interest Determination Date, which would affect the amount of any interest payments under the senior notes and, by extension, could affect their market value.

***Events for which acceleration rights under the senior notes may be exercised are more limited than those available under the terms of our outstanding senior debt securities issued prior to August 21, 2023.***

On August 21, 2023, we entered into a fifth supplemental senior indenture between us and the trustee, pursuant to which the terms of our senior debt securities issued pursuant to the senior indenture on or after August 21, 2023, including the senior notes, will be modified. The modifications to the terms of our senior debt securities issued pursuant to the senior indenture on or after August 21, 2023, including the senior notes, include, among other things, limiting the circumstances under which the payment of the principal amount of such senior debt securities issued on or after August 21, 2023 can be accelerated.

All or substantially all of our outstanding senior debt securities issued prior to August 21, 2023 (the "existing senior debt securities") provide acceleration rights for nonpayment of principal, premium (if any), or interest and for certain events relating to our bankruptcy, insolvency or reorganization. The existing senior debt securities also provide acceleration rights for our failure to perform any other covenant or warranty in the senior indenture under which such existing senior debt securities were issued for 90 days after we have received written notice of such failure. In addition, the existing senior debt securities require a 30-day cure period before a nonpayment of interest becomes an event of default and acceleration rights become exercisable with respect to such nonpayment, but no such cure period for nonpayment of principal or premium, if any.

Under the fifth supplemental senior indenture, we modified the terms of our senior indenture so that payment of the principal amount of the senior notes may be accelerated only for (i) our failure to pay principal, premium (if any) or interest on the senior notes and, in each case, such nonpayment continues for 30 days after such payment is due or (ii) the occurrence of certain events of bankruptcy, insolvency or reorganization of us (but not the Bank). The principal amount of the senior notes may not be accelerated if we fail to perform any covenant or warranty (other than nonpayment of principal, premium (if any) or interest where such nonpayment continues for 30 days after such payment is due) after we have received written notice of such failure or if we fail to make a sinking fund payment.

As a result of these differing provisions, if we fail to perform any covenant (other than nonpayment of principal, premium (if any) or interest) that applies both to the senior notes and to any existing senior debt securities, the trustee and the holders of the existing senior debt securities would have acceleration rights that would not be available to the trustee or the holders of the senior notes offered hereby. In addition, if we fail to pay the principal of any existing senior debt securities when due, an event of default would occur immediately with respect to such existing senior debt securities (and the exercise of acceleration rights could proceed immediately in accordance with the provisions of the senior base indenture (as defined herein) and supplemental senior indentures under which such existing senior debt securities were issued), whereas, if we fail to pay the principal of the senior notes when due, the trustee and the holders of the senior notes must wait for the 30-day cure period to expire before such nonpayment of principal becomes an Event of Default and any acceleration rights are triggered with respect to such nonpayment. Any repayment of the principal amount of existing senior debt securities following the exercise of acceleration rights in circumstances in which such rights are not available to the holders of the senior notes could adversely affect our ability to make timely payments on the senior notes thereafter. These limitations on the rights and remedies of holders of the senior notes could adversely affect the market value of the senior notes, especially during times of financial stress for us or our industry.

#### **TABLE OF CONTENTS**
***Holders of the notes could be at greater risk for being structurally subordinated if we sell or convey all or substantially all of our assets to one or more of our majority-owned subsidiaries.***

If we sell or convey all or substantially all of our assets to one or more of our direct or indirect majority-owned subsidiaries, under the senior indenture, as supplemented by the fifth and ninth supplemental senior indentures, and under the subordinated indenture, as supplemented by the fourth supplemental subordinated indenture, such subsidiary or subsidiaries will not be required to assume our obligations under the notes, and we will remain the sole obligor on the notes. In such event, creditors of any such subsidiary or subsidiaries would have additional assets from which to recover on their claims while holders of the notes would be structurally subordinated to creditors of such subsidiary or subsidiaries with respect to such assets. See "Description of Notes—Senior Notes—Merger, Consolidation or Sale of Assets" and "Description of Notes—Subordinated Notes—Merger, Consolidation or Sale of Assets" in this prospectus supplement.

***The interest rate on the subordinated notes will reset on the subordinated notes Reset Date and may result in an interest rate that is less than the initial fixed annual rate of 5.605% in effect until the subordinated notes Reset Date.***

The interest rate on the subordinated notes on and after the subordinated notes Reset Date will equal the Five-year U.S. Treasury Rate as of the subordinated notes Reset Determination Date, plus 1.350% per annum. Therefore, the interest rate on the subordinated notes on and after the subordinated notes Reset Date could be more or less than the initial fixed rate of 5.605%. We have no control over the factors that may affect U.S. Treasury Rates, including geopolitical conditions and economic, financial, political, regulatory, judicial or other events that may impact U.S. Treasury Rates.

#### The historical Five-year U.S. Treasury Rates are not an indication of future Five-year U.S. Treasury Rates.
In the past, U.S. Treasury Rates have experienced significant fluctuations. You should note that historical levels, fluctuations and trends of U.S. Treasury Rates are not necessarily indicative of future levels. Any historical upward or downward trend in U.S. Treasury Rates is not an indication that U.S. Treasury Rates are more or less likely to increase or decrease at any time, and you should not take the historical U.S. Treasury Rates as an indication of future rates.

#### Our obligations under the subordinated notes will be unsecured and subordinated.
Our obligations under the subordinated notes will be unsecured and subordinated in right of payment to all of our existing and future Senior Debt (as defined herein), which includes, among other things, our debt to general creditors. As of September 30, 2025, we had approximately $8.7 billion of Senior Debt, approximately $4.1 billion of indebtedness ranking on a parity with the subordinated notes and approximately $4.5 billion of indebtedness ranking junior to the subordinated notes, including our junior subordinated debentures or indentures, as applicable, issued to our statutory trusts. As of that date, we had a total consolidated indebtedness of $17.3 billion, including $10.4 billion of indebtedness of our subsidiaries. We may incur substantial other indebtedness, including additional Senior Debt and indebtedness ranking on a parity with the subordinated notes, in the future. The subordinated indenture governing the subordinated notes does not contain any limitation on the amount of debt or other obligations ranking senior to or pari passu with the indebtedness evidenced by the subordinated notes that we may incur hereafter.

#### Risks Relating to the Benchmark for the Senior Notes

#### SOFR has a relatively limited history in the marketplace.
For each Floating Rate Interest Period, the interest rate on the senior notes is based on a compounded SOFR index rate calculated using the formula described in "Description of Notes" below. Since SOFR has a limited history in the marketplace, the senior notes may have no established trading market when issued, and an established trading market may never develop or may not be very liquid. The senior notes may not be able to be sold or may not be able to be sold at prices that will provide a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

Market terms for debt securities indexed to SOFR, such as the spread over the index reflected in interest rate provisions and the formula and related conventions described in "Description of Notes" below to calculate Compounded SOFR Index Rate for the senior notes, may evolve over time, and trading prices of the senior notes

S-13<br>

------

#### **TABLE OF CONTENTS**
may be lower than those of later-issued SOFR-linked debt securities which contain more settled and different market terms as a result. In particular, the Issuer may in the future also issue securities referencing SOFR that differ materially in terms of interest determination when compared with any previous SOFR-referenced securities, including the senior notes.

You should carefully consider how any mismatch between the adoption of SOFR-based reference rates across these markets may impact any hedging or other financial arrangements that you may put in place in connection with any acquisition, holding or disposal of the senior notes.

#### SOFR may be more volatile than other benchmark or market rates.
Since the initial publication of SOFR, daily changes in SOFR have, on occasion, been more volatile than daily changes in other benchmark or market rates. Although changes in Compounded SOFR generally are not expected to be as volatile as changes in daily levels of SOFR, the return on and value of the senior notes may fluctuate more than senior notes that are linked to less volatile rates. In addition, the volatility of SOFR has reflected the underlying volatility of the overnight U.S. Treasury repo market. The Federal Reserve Bank of New York has at times conducted operations in the overnight U.S. Treasury repo market in order to help maintain the federal funds rate within a target range. There can be no assurance that the Federal Reserve Bank of New York will continue to conduct such operations in the future, and the duration and extent of any such operations is inherently uncertain. The effect of any such operations, or of the cessation of such operations to the extent they are commenced, is uncertain and could be materially adverse to investors in the senior notes. Furthermore, investors should not rely on any historical changes or trends in SOFR as an indicator of future changes in SOFR.

#### Compounded SOFR Index Rate will only be capable of being determined near the end of the relevant Floating Rate Interest Period.
The level of Compounded SOFR Index Rate applicable to a particular Floating Rate Interest Period and, therefore, the amount of interest payable with respect to such Floating Rate Interest Period will be determined on the Interest Determination Date for such Floating Rate Interest Period. Because each such date is near the end of such Floating Rate Interest Period, you will not know the amount of interest payable with respect to a particular Floating Rate Interest Period until shortly prior to the related Floating Rate Period Interest Payment Date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each such Floating Rate Period Interest Payment Date. In addition, some investors may be unwilling or unable to trade the senior notes without changes to their information technology systems, which could adversely impact the liquidity and trading price of the senior notes.

#### SOFR may be modified or discontinued by its administrator.
SOFR has a limited history in the marketplace, and the NY Federal Reserve (or a successor), as administrator of SOFR, may make methodological or other changes that could change the value of SOFR, including changes related to the method by which SOFR is calculated, eligibility criteria applicable to the transactions used to calculate SOFR, or timing related to the publication of SOFR (which may include withdrawing, suspending or discontinuing the calculation or dissemination of SOFR). The NY Federal Reserve may make any or all of these changes in its sole discretion and without notice, and it has no obligation to consider the interests of holders of the senior notes in calculating, withdrawing, modifying, amending, suspending or discontinuing SOFR. Because SOFR is published by the NY Federal Reserve based on data received from other sources, the Issuer has no control over its determination, calculation or publication.

There can be no guarantee that SOFR will not be modified or discontinued in a manner that is materially adverse to you. If the manner in which SOFR is calculated is changed or if SOFR is discontinued, that change or discontinuance may result in a reduction or elimination of the amount of interest payable on the senior notes and a reduction in their trading prices.

#### Uncertainty relating to the regulation of benchmarks may adversely affect the value of the senior notes.
SOFR and other interest rates or other types of rates and indices which are deemed to be "benchmarks" are the subject of ongoing national and international regulatory discussions and proposals for reform. Some of these reforms are already effective, while others are still to be implemented. Following the implementation of any such reforms,

S-14<br>

------

#### **TABLE OF CONTENTS**
the manner of administration of benchmarks, including SOFR, may change, with the result that they may perform differently than in the past, or the benchmark could be eliminated entirely, or there could be other consequences that cannot be predicted. Any of the foregoing may have an adverse effect on the value of the senior notes.

#### Interest on the senior notes during the Floating Rate Period will be calculated using the Benchmark Replacement if a Benchmark Transition Event occurs.
To the extent SOFR is discontinued or is no longer quoted, floating interest rates will be determined using the alternative methods described under "Description of Notes—Senior Notes—Interest—Benchmark Transition Provisions." In particular, if we or our designee (in consultation with us) determine that a Benchmark Transition Event and related Benchmark Replacement Date have occurred, we or our designee (in consultation with us) will use the Benchmark Replacement for the purposes of determining the floating interest rates, as well as to make certain changes to the manner in which floating interest rates are calculated or determined (in consultation with the calculation agent).

This Benchmark Replacement may result in interest payments that are lower than, or that do not otherwise correlate over time with, the payments that would have been made on the senior notes if SOFR was available in its current form. Additionally, if SOFR is no longer calculated or administered and no Benchmark Replacement is calculated (including because the same costs and risks that may lead to the discontinuation or unavailability of SOFR make the Benchmark Replacement impossible or impracticable to determine), the floating interest rate on the senior notes may accrue at the same rate as the immediately preceding Floating Rate Interest Period (or, in the case of the initial Floating Rate Interest Period, the Initial Interest Rate), effectively converting the senior notes (during the Floating Rate Period) into fixed rate instruments. Due to the uncertainty concerning the availability of benchmark replacements, the relevant fallback provisions may not operate as intended at the relevant time. Any of the foregoing may have an adverse effect on the value of the senior notes.

***The rate of interest on the senior notes during the Floating Rate Period may be determined by reference to a Benchmark Replacement even if SOFR continues to be published, which could adversely affect the value of the senior notes.***

If a Benchmark Transition Event and related Benchmark Replacement Date occur with respect to SOFR, the rate of interest on the senior notes during the Floating Rate Period will thereafter be determined by reference to the Benchmark Replacement. A Benchmark Transition Event includes, among other things, a public statement or publication of information by the regulatory supervisor for the administrator of SOFR announcing that SOFR is no longer representative. The rate of interest on the senior notes may therefore cease to be determined by reference to SOFR, and instead be determined by reference to the Benchmark Replacement, even if SOFR continues to be published. Such rate may be lower than SOFR for so long as SOFR continues to be published, and the value of and return on the senior notes may be adversely affected.

#### Any Benchmark Replacement will likely be a relatively new market index that may be altered or discontinued.
The Benchmark Transition Provisions specify a "waterfall" of alternative rates that may become the Benchmark Replacement. These alternative rates are uncertain and no market convention currently exists, or may ever exist, for their determination. For example, the ISDA Fallback Rate, which is the rate referenced in the ISDA Definitions that is to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor, has not been established as of the date hereof. Even after the ISDA Fallback Rate is initially determined, ISDA Definitions and the ISDA Fallback Rate may change over time. Uncertainty surrounding the establishment of market conventions related to the calculation of the ISDA Fallback Rate and other alternative rates, and whether any of the alternative rates is a suitable replacement or successor for SOFR, may adversely affect the value of and return on the senior notes.

The Benchmark Transition Provisions provide for a Benchmark Replacement Adjustment to be added to the Unadjusted Benchmark Replacement in order to make the Unadjusted Benchmark Replacement more comparable to SOFR. However, such adjustment will not necessarily make the Unadjusted Benchmark Replacement equivalent to SOFR. In particular, the Benchmark Replacement Adjustment may be a onetime adjustment, so such adjustment above the applicable Unadjusted Benchmark Replacement may not respond to changes in unsecured bank credit risk or other market conditions on a periodic basis.

Further, (i) any failure of the Benchmark Replacement to gain market acceptance could adversely affect the senior notes, (ii) the Benchmark Replacement may have a very limited history and the future performance of the

S-15<br>

------

#### **TABLE OF CONTENTS**
Benchmark Replacement may not be able to be predicted based on historical performance, (iii) the secondary trading market for debt securities linked to the Benchmark Replacement may be limited and (iv) the administrator of the Benchmark Replacement may make changes that could change the value of the Benchmark Replacement or discontinue the Benchmark Replacement and would not have any obligation to consider the interests of holders of notes in doing so.

***We or our designee (after consulting with us) may make determinations with respect to the senior notes that could affect the value of and return on the senior notes.***

We or our designee (in consultation with us) may make certain determinations with respect to the senior notes as further described in this prospectus supplement that may adversely affect the value of and return on the senior notes. In particular, if a Benchmark Transition Event and related Benchmark Replacement Date occur, we or our designee (in consultation with us) will determine the Benchmark Replacement and the Benchmark Replacement Adjustment and can make Benchmark Replacement Conforming Changes in connection with the implementation of the applicable Benchmark Replacement as described below under "Description of Notes—Senior Notes—Interest—Benchmark Transition Provisions." These determinations may require the exercise of discretion and the making of subjective judgments (such as, for example, determining the occurrence or non-occurrence of a Benchmark Transition Event).

Benchmark Replacements and Benchmark Replacement Adjustments may be selected or formulated by (i) the Relevant Governmental Body (such as the Alternative Reference Rates Committee convened by the Federal Reserve and the NY Federal Reserve), (ii) ISDA, or (iii) in certain circumstances, us (or one of our affiliates). In addition, the Benchmark Transition Provisions expressly authorize us or our designee (in consultation with us) to make Benchmark Replacement Conforming Changes with respect to, among other things, the determination of Floating Rate Interest Periods and the timing and frequency of determining rates and making payments of interest; in each case that we or our designee (in consultation with us) determines, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if we or our designee (in consultation with us) decides that implementation of any portion of such market practice is not administratively feasible or determines that no market practice for use of the Benchmark Replacement exists, in such other manner as we or our designee (in consultation with us) determines is appropriate (acting in good faith)).

Any determination, decision or election that may be made by us or our designee (after consulting with us) pursuant to the Benchmark Transition Provisions will, in each case, become effective without consent from the holders of the senior notes or any other party. Any designee that we may appoint in connection with these determinations may be our affiliate. When performing such functions, potential conflicts of interest may exist between us, our designee or the calculation agent and holders of the senior notes. All determinations by us or our designee (after consulting with us) will be conclusive for all purposes and binding on us and holders of the senior notes absent manifest error. In making these potentially subjective determinations, we, our designee or the calculation agent may have economic interests that are adverse to your interests, and such determinations may adversely affect the value of and return on the senior notes. Because the Benchmark Replacement is uncertain, we or our designee (in consultation with us) are likely to exercise more discretion in respect of calculating interest payable on the senior notes during the Floating Rate Period than would be the case in the absence of a Benchmark Transition Event and related Benchmark Replacement Date. Neither they nor we will have any obligation to consider your interests as a holder of the senior notes in taking any action that might affect the value of the senior notes.

The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest payable on the senior notes, which could adversely affect the return on, value of and market for such notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark that it is replacing.

#### Risks Related to Acquisitions
***We grow our business in part by acquiring other financial services businesses and businesses with technologies or other assets valuable to us from time to time. Acquisitions present several risks and uncertainties related both to the acquisition transactions themselves and to the integration of the acquired businesses into Huntington after closing.***

Acquisitions of other companies or of financial assets and deposits and other liabilities present risks and uncertainties to us in addition to those presented by the nature of the business acquired, which may materially and adversely affect our results of operations. Many of the same risks arise when we engage in strategic partnerships. Our ability to analyze the risks presented by prospective acquisitions, as well as our ability to prepare in advance of closing for integration, may be limited to the extent that we cannot gather necessary or desirable information with respect to the business we are acquiring. We may also make certain assumptions related to an acquisition that may prove to be inaccurate, that limit the anticipated benefits (such as cost savings from synergies or strategic gains from being able to offer enhanced product sets) or make the acquisition more expensive or take longer to complete and integrate than anticipated. Prior to closing an acquisition, prospective acquisition targets are also subject to their own risks that we cannot manage or control. Our ability to complete an acquisition may be dependent on regulatory agencies with responsibilities for reviewing or approving the transaction, which could delay, restrictively condition or result in denial of an acquisition, or otherwise limit the benefits of the acquisition. Changes in regulatory rules or standards or the application of those rules or standards, or future regulatory initiatives designed to promote competition or limit systemic risk and the potential for a financial institution to become "too big to fail," may also limit our ability to complete an acquisition.

Acquisition targets have their own risks specific to their businesses that could impact the success of an acquisition and its integration into Huntington, such as:

&nbsp;&nbsp;&nbsp;&nbsp;• If a significant aspect of the value of transaction is intellectual property, the extent to which the intellectual property may be utilized or protected and commercialized by Huntington.

&nbsp;&nbsp;&nbsp;&nbsp;• If the acquisition includes loan portfolios, the extent of actual credit losses and the required allowance for credit losses following completion of the acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;• If the acquisition involves entering into new businesses or geographic or other markets, potential limitations on our ability to take advantage of these opportunities because of our inexperience with respect to them.

&nbsp;&nbsp;&nbsp;&nbsp;• The results of litigation and governmental investigations that may be pending at the time of the acquisition or that may be filed or commenced thereafter, because of an acquisition or otherwise, which are often hard to predict.

&nbsp;&nbsp;&nbsp;&nbsp;• Operational or compliance issues at the acquisition target may not be fully identified or remediated until after the acquisition closes, potentially resulting in increased costs or penalties.

&nbsp;&nbsp;&nbsp;&nbsp;• Models used by an acquisition target, such as for capital planning and credit loss accounting, may be designed or implemented in a manner different than at Huntington, and our necessary reliance on these for a period of time, could materially impact our financial condition or results of operations to the extent that our estimates based on these models are inaccurate.

&nbsp;&nbsp;&nbsp;&nbsp;• Enterprise risk management systems, policies and procedures may be different and less mature than those of Huntington, and our necessary reliance on these for a period of time, could limit our ability to identify, monitor, manage and report risks or subject us to heightened regulatory, legal, operational or reputational risk.

After closing, the success of an acquisition is likely partially dependent on our ability to retain and expand upon the acquired company's customer base. It is also frequently subject to risks related to human capital, including, risks related to integrating the corporate culture of the acquired company and, to the extent being retained, the quality of leadership of the acquired company.

#### We expect to continue to incur substantial costs related to the Veritex Merger and the Cadence Merger.
We have incurred substantial costs in connection with the merger of Veritex with and into Huntington (the "Veritex Merger") and the Cadence Merger and subsequent integration of the processes, policies, procedures, operations, and technologies and systems, including purchasing, accounting and finance, payroll, compliance, treasury management, branch operations, vendor management, risk management, lines of business, pricing and

S-17<br>

------

#### **TABLE OF CONTENTS**
benefits. While we have attempted to accurately forecast these costs, factors that are beyond our control or that we have failed to accurately estimate could result in us incurring future charges in excess of our current estimates. These charges could be material and could materially adversely affect our future earnings.

***The integration of Huntington, Veritex and Cadence may be more difficult, costly or time consuming than expected and Huntington may fail to realize the anticipated benefits of the Veritex Merger and the Cadence Merger.***

The success of the Veritex Merger and the Cadence Merger will depend, in part, on the ability to realize the anticipated growth opportunities and cost savings from combining the businesses of Huntington, Veritex and Cadence. To realize the anticipated benefits and cost savings from the Veritex Merger and the Cadence Merger, we must successfully integrate and combine the businesses of Huntington, Veritex and Cadence in a manner that permits those cost savings to be realized. If we are not able to successfully achieve these objectives, or if we have failed to accurately estimate the anticipated benefits of the Veritex Merger and the Cadence Merger, the anticipated benefits may not be realized fully or at all, they may take longer to realize than expected, and we may incur additional unforeseen expenses.

The integration process could result in the loss of key employees, diversion of management attention and resources, the disruption of the combined company's ongoing businesses or inconsistencies in standards, controls, procedures and policies that may adversely affect the combined company's ability to maintain relationships with clients, customers, depositors and employees. It is possible that the continued integration of Veritex's and Cadence's businesses into Huntington's business could result in the loss of key employees, the disruption of Huntington's business or inconsistencies in standards, controls, procedures and policies that adversely affect Huntington's ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the Veritex Merger and the Cadence Merger. Integration efforts may also divert management attention and resources. These integration matters could have an adverse effect on the combined company for an undetermined period.

#### Our future results may suffer if we do not effectively manage our expanded operations.
As a result of the Veritex Merger and the Cadence Merger, the size, scope, and complexity of our business has increased significantly beyond that of the business of Huntington, Veritex and Cadence prior to the Veritex Merger and the Cadence Merger. Our future success will depend, in part, upon our ability to manage and achieve the benefits we have anticipated will be associated with this expanded business, challenges, including challenges related to the management and monitoring of new operations and the associated increased costs and complexity of the combined company. There can be no assurances that we will be successful or that we will realize the expected operating efficiencies, cost savings, growth opportunities, revenue enhancements or other benefits currently anticipated. We may also face increased scrutiny from governmental authorities as a result of the significant increase in the size of our business. In particular, Huntington will become subject to higher regulatory and supervisory standards from governmental authorities as a result of the significant increase in the size of its business following the consummation of the Cadence Merger, which will cause Huntington to become subject to standards applicable to Category III banking organizations under the Federal Reserve's Regulation YY, following the applicable transition period. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from the Veritex Merger and the Cadence Merger.

***The combined company may be unable to retain Huntington or Cadence personnel successfully while the Cadence Merger is pending or after the Cadence Merger is completed.***

The success of the Cadence Merger will depend in part on the combined company's ability to retain the talents and dedication of key employees currently employed by Huntington and Cadence. It is possible that these employees may decide not to remain with Huntington or Cadence, as applicable, while the Cadence Merger is pending or with the combined company after the Cadence Merger is consummated. If Huntington and Cadence are unable to retain key employees, including management, who are critical to the successful integration and future operations of the companies, Huntington and Cadence could face disruptions in their operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment costs. In addition, if key employees terminate their employment, or if an insufficient number of employees are retained to maintain effective operations, the combined company's business activities may be adversely affected and management's attention may be diverted from successfully integrating the Bank and Cadence to hiring suitable replacements, all of which may cause the combined company's business to suffer. In addition, Huntington and Cadence may not be able to locate or retain suitable replacements for any key employees who leave any of the companies.

#### DESCRIPTION OF NOTES

#### Senior Notes

#### General
We will issue $1,000,000,000 aggregate principal amount of fixed-to-floating rate senior notes due 2032 (the "senior notes"). The senior notes will be a series of our senior debt securities. The senior notes will be issued under a senior indenture, dated as of December 29, 2005, 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, as amended or supplemented from time to time and as amended by the fifth supplemental senior indenture, dated as of August 21, 2023, and the ninth supplemental senior indenture, to be dated as of January 28, 2026, each between us and the trustee. Throughout this section of the description of notes, we refer to both the senior indenture as the "senior base indenture" and the senior base indenture and supplemental senior indentures together as the "senior indenture." The following description of the senior notes may not be complete and is subject to and qualified in its entirety by reference to the senior indenture. Wherever we refer to particular sections or defined terms of the senior indenture, it is our intent that those sections or defined terms will be incorporated by reference in this prospectus supplement.

The senior 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 senior notes on any securities exchange. The senior notes will be unsecured and unsubordinated and will rank equally among themselves and with all of our other unsecured and unsubordinated indebtedness. The senior notes will not be guaranteed by any of our subsidiaries. Our subsidiaries may, without notice or consent of the holders of the senior notes, incur additional debt or liabilities in the future, all of which would rank structurally senior to the senior notes. Huntington may from time to time, without notice or consent of the holders of the senior notes, incur additional senior indebtedness ranking equally with the senior notes, as well as additional subordinated indebtedness ranking junior to the senior notes. As of September 30, 2025, the aggregate amount of all debt and other liabilities of our subsidiaries, including deposits, was approximately $187 billion.

Because we are a holding company, our rights and the rights of our creditors, including holders of the senior 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 senior notes will be subject to defeasance under the conditions described below in "—Discharge, Defeasance and Covenant Defeasance."

The senior notes are not savings accounts, deposits or other obligations of any of our bank or non-bank subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or instrumentality.

We will initially issue $1,000,000,000 aggregate principal amount of the senior notes. We may, without the consent of the holders of the senior notes, increase the principal amount of the senior notes by issuing such 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 such additional notes, and with the same CUSIP number as the senior notes offered by this prospectus supplement; provided that if any such additional notes are not fungible with the senior 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 senior notes offered by this prospectus supplement and any additional notes of such series would rank equally and ratably and would be treated as a single series for all purposes under the senior indenture.

The senior notes will mature at 100% of their principal amount on January 28, 2032 (the "senior notes Maturity Date"), unless earlier redeemed or repaid as described below under "—Optional Redemption—Senior Notes." The senior notes will not be subject to repayment at the option of the holder at any time prior to the senior notes Maturity Date and will not be entitled to any sinking fund.

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.

#### **TABLE OF CONTENTS**

#### Interest
From (and including) January 28, 2026 (the "senior notes Issue Date") to (but excluding) January 28, 2031 (the "Fixed Rate Period"), interest on the senior notes will be payable at a rate of 4.623% per annum (the "Initial Interest Rate"). With respect to the Fixed Rate Period, interest on the senior notes will be payable semi-annually in arrears on each January 28 and July 28, commencing on July 28, 2026 and ending on January 28, 2031 (each, a "Fixed Rate Period Interest Payment Date").

From (and including) January 28, 2031 to (but excluding) the senior notes Maturity Date or date of redemption or repayment (the "Floating Rate Period"), the interest rate on the senior notes will be equal to the Benchmark (as defined below) plus 99.0 basis points per annum (the "Spread"). During the Floating Rate Period, interest on the senior notes will be payable quarterly in arrears on April 28, 2031, July 28, 2031, October 28, 2031 and on the senior notes Maturity Date or date of redemption or repayment (each, a "Floating Rate Period Interest Payment Date").

Fixed Rate Period:

&nbsp;&nbsp;&nbsp;&nbsp;• Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

&nbsp;&nbsp;&nbsp;&nbsp;• If any scheduled Fixed Rate Period Interest Payment Date is not a Business Day, any payment of principal and interest will be postponed to the next day that is a Business Day, but interest on that payment will not accrue during the period from and after the scheduled Fixed Rate Period Interest Payment Date.

Floating Rate Period:

&nbsp;&nbsp;&nbsp;&nbsp;• Interest will be computed for the period from (and including) a Floating Rate Period Interest Payment Date and ending on (but excluding) the next succeeding Floating Rate Period Interest Payment Date or the senior notes Maturity Date or date of redemption or repayment (each, a "Floating Rate Interest Period"); provided that the first Floating Rate Interest Period for the senior notes will begin on (and include) January 28, 2031 and will end on (but exclude) the first Floating Rate Period Interest Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;• The interest rate on the senior notes will be calculated quarterly on the second U.S. Government Securities Business Day preceding the applicable Floating Rate Period Interest Payment Date, except as described below (the "Interest Determination Date"). In no event will the interest payable on the senior notes be less than zero. Interest will be computed on the basis of the actual number of days in each Floating Rate Interest Period and a 360-day year. The amount of accrued interest payable on the senior notes for each Floating Rate Interest Period will be computed by multiplying (i) the outstanding principal amount of the senior notes by (ii) the product of (a) the interest rate for the relevant Floating Rate Interest Period multiplied by (b) the quotient of the actual number of calendar days in the applicable Floating Rate Interest Period relating to such Floating Rate Interest Period divided by 360.

&nbsp;&nbsp;&nbsp;&nbsp;• If any scheduled Floating Rate Period Interest Payment Date (other than the senior notes Maturity Date) is not a Business Day, such Floating Rate Period Interest Payment Date will be postponed to the next day that is a Business Day; provided that if that Business Day falls in the next succeeding calendar month, such Floating Rate Period Interest Payment Date will be the immediately preceding Business Day. If any such Floating Rate Period Interest Payment Date (other than the senior notes Maturity Date) is postponed or brought forward as described above, the payment of interest due on such postponed or brought forward Floating Rate Period Interest Payment Date will include interest accrued to but excluding such postponed or brought forward Floating Rate Period Interest Payment Date.

If the senior notes Maturity Date or date of redemption or repayment of the senior notes is not a Business Day, we may pay interest and principal on the next succeeding Business Day, but interest on that payment will not accrue during the period from and after the senior notes Maturity Date or date of redemption or repayment of the senior notes. If a date of redemption or repayment of the senior notes falls within the Floating Rate Period but does not occur on a Floating Rate Period Interest Payment Date, (i) the related Interest Determination Date shall be deemed to be the date that is two U.S. Government Securities Business Days prior to such date of redemption or repayment, (ii) the related Observation Period shall be deemed to end on (and exclude) the second U.S. Government Securities Business Day falling prior to such date of redemption or repayment, (iii) the senior notes Floating Rate Interest Period will be deemed to be shortened accordingly and (iv) corresponding adjustments will be deemed to be made to the Compounded SOFR Index Rate formula (or applicable benchmark).

The regular record dates for the senior notes will be the fifteenth calendar day preceding each Floating Rate Period Interest Payment Date or Fixed Rate Period Interest Payment Date, as applicable, whether or not a Business Day.

#### Calculation of the Benchmark
The "Benchmark" means, initially, the Compounded SOFR Index Rate; provided that if a Benchmark Transition Event and related Benchmark Replacement Date have occurred with respect to SOFR or the then-current Benchmark, then "Benchmark" means the Benchmark Replacement.

"Compounded SOFR Index Rate" means, in relation to a Floating Rate Interest Period, the rate computed by the calculation agent in accordance with the following formula:

![](ny20061696x3_equation01.jpg)<br>

&nbsp;&nbsp;&nbsp;&nbsp;<br>

Where:

"d" is the number of calendar days from (and including) SOFR IndexStart to (but excluding) SOFR IndexEnd (being the number of calendar days in the Observation Period);

"SOFR IndexStart" is the SOFR Index value for the day which is two U.S. Government Securities Business Days preceding the first date of the relevant Floating Rate Interest Period;

"SOFR IndexEnd" is the SOFR Index value for the day which is two U.S. Government Securities Business Days preceding the Floating Rate Period Interest Payment Date relating to such Floating Rate Interest Period;

"SOFR Index" means, with respect to any U.S. Government Securities Business Day:

(1)<br> the SOFR Index value as published by the SOFR Administrator as such index appears on the SOFR Administrator's Website at the SOFR Determination Time; provided that:

(2) if a SOFR Index value does not so appear as specified in (1) above at the SOFR Determination Time, then (i) if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR Index Rate shall be the rate determined pursuant to the "SOFR Index Unavailability" provisions below or (ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred in respect of SOFR, then Compounded SOFR Index Rate shall be the rate determined pursuant to the "Benchmark Transition Provisions" below. 

"SOFR" means, with respect to any U.S. Government Securities Business Day, the rate determined by the calculation agent in accordance with the following provisions:

(1)<br> the Secured Overnight Financing Rate published for such U.S. Government Securities Business Day as such rate appears on the NY Federal Reserve's website on the immediately following U.S. Government Securities Business Day at the SOFR Determination Time; and

(2)<br> if the rate does not so appear, the Secured Overnight Financing Rate published on the NY Federal Reserve's website for the first preceding U.S. Government Securities Business Day for which the Secured Overnight Financing Rate was published on the NY Federal Reserve's website.

"NY Federal Reserve's website" means the website of the Federal Reserve Bank of New York (the "NY Federal Reserve"), currently at *http://www.newyorkfed.org*, or any successor website of the NY Federal Reserve or the website of any successor administrator of the Secured Overnight Financing Rate. The foregoing website is an inactive textual reference only, meaning that the information contained on the website is not part of this prospectus supplement or the accompanying prospectus or incorporated herein or therein.

"Observation Period" means, in respect of each Floating Rate Interest Period, the period from (and including) the day falling two U.S. Government Securities Business Days prior to the first day of the relevant Floating Rate Interest Period to (but excluding) the day falling two U.S. Government Securities Business Days prior to the relevant Floating Rate Period Interest Payment Date for such Floating Rate Interest Period.

"SOFR Administrator" means the NY Federal Reserve (or a successor administrator of SOFR).

#### **TABLE OF CONTENTS**
"SOFR Administrator's Website" means the website of the NY Federal Reserve, currently at *http://www.newyorkfed.org*, or any successor source. The foregoing website is an inactive textual reference only, meaning that the information contained on the website is not part of this prospectus supplement or the accompanying prospectus or incorporated herein or therein.

"SOFR Determination Time" means, with respect to any U.S. Government Securities Business Day, 3:00 p.m. (New York City time) on such U.S. Government Securities Business Day.

"U.S. Government Securities Business Day" means any day except for a Saturday, Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding clauses (1) and (2) of the definition of "SOFR" above, if we or our designee (in consultation with us) determine on or prior to the relevant Interest Determination Date that a Benchmark Transition Event and related Benchmark Replacement Date have occurred with respect to SOFR, then the "Benchmark Transition Provisions" set forth below will thereafter apply to all determinations of the rate of interest payable on the senior notes during the Floating Rate Period.

In accordance with and subject to the Benchmark Transition Provisions, after a Benchmark Transition Event and related Benchmark Replacement Date have occurred, the amount of interest that will be payable for each interest period on the senior notes during the Floating Rate Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Spread.

"designee" means our affiliate or any other agent.

"Reference Time" means (1) if the Benchmark is Compounded SOFR Index Rate, the SOFR Determination Time, and (2) if the Benchmark is not Compounded SOFR Index Rate, the time determined by us or our designee (in consultation with us) in accordance with the Benchmark Replacement Conforming Changes.

#### SOFR Index Unavailability
If SOFR IndexStart or SOFR IndexEnd is not published on the relevant Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, "Compounded SOFR Index Rate" will mean, for the relevant interest period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR Averages, and definitions required for such formula, published on the SOFR Administrator's Website at *https://www.newyorkfed.org/markets/treasury-repo-reference-rates-information* (or such successor website). For the purposes of this provision, references in the SOFR Averages compounding formula and related definitions to "calculation period" shall be replaced with "Observation Period" and the words "that is, 30-, 90-, or 180-calendar days" shall be removed. If the daily SOFR ("SOFRi") does not so appear for any day, "i" in the Observation Period, SOFRi for such day "i" shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator's Website.

#### Benchmark Transition Provisions
If we or our designee (in consultation with us) determine that a Benchmark Transition Event and related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark on any date, the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the senior notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; provided that, if we or our designee (in consultation with us) are unable to or do not determine a Benchmark Replacement in accordance with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, the interest rate for the related Floating Rate Interest Period will be equal to the interest rate in effect for the immediately preceding Floating Rate Interest Period or, in the case of the Interest Determination Date prior to the first Floating Rate Period Interest Payment Date, the Initial Interest Rate.

"Benchmark Replacement" means the first alternative set forth in the order below that can be determined by us or our designee (in consultation with us) as of the Benchmark Replacement Date:

(1)<br> the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor (if any) and (b) the Benchmark Replacement Adjustment;

S-24<br>

------

#### **TABLE OF CONTENTS**
(2)<br> the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; and

(3) the sum of: (a) the alternate rate of interest that has been selected by us or our designee (in consultation with us) as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment. 

In connection with the implementation of a Benchmark Replacement, we or our designee (in consultation with us) will have the right to make changes to (1) any Interest Determination Date, Floating Rate Period Interest Payment Date, Reference Time, business day convention or Floating Rate Interest Period, (2) the manner, timing and frequency of determining the rate and amounts of interest that are payable on the senior notes during the Floating Rate Period and the conventions relating to such determination and calculations with respect to interest, (3) rounding conventions, (4) tenors and (5) any other terms or provisions of the senior notes during the Floating Rate Period, in each case that we or our designee (in consultation with us) determine, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if we or our designee (in consultation with us) decide that implementation of any portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement exists, in such other manner as we or our designee (in consultation with us) determine is appropriate (acting in good faith)) (the "Benchmark Replacement Conforming Changes"). Any Benchmark Replacement Conforming Changes will apply to the senior notes for all future Floating Rate Interest Periods.

We will promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the trustee, the paying agent, the calculation agent and the holders of senior notes; provided that failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

All determinations, decisions, elections and any calculations made by us or our designee for the purposes of determining the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes will be conclusive and binding on the holders of senior notes, us, the calculation agent, the trustee and the paying agent, absent manifest error. If made by our designee, such determinations, decisions, elections and calculations will be made after consulting with us, and our designees will not make any such determination, decision, election or calculation to which we object. Notwithstanding anything to the contrary in the senior indenture or the senior notes, any determinations, decisions, calculations or elections made in accordance with this provision will become effective without consent from the holders of senior notes or any other party.

Any determination, decision or election relating to the Benchmark will be made by us on the basis described above. The calculation agent shall have no liability for not making any such determination, decision or election. In addition, we may designate an entity (which may be our affiliate) to make any determination, decision or election that we have the right to make in connection with the determination of the Benchmark.

Notwithstanding any other provision of "Benchmark Transition Provisions" set forth above, no Benchmark Replacement will be adopted, nor will the applicable Benchmark Replacement Adjustment be applied, nor will any Benchmark Replacement Conforming Changes be made, if in our determination, the same could reasonably be expected to prejudice the qualification of the senior notes as eligible liabilities or loss absorbing capacity instruments for the purposes of the Relevant Rules.

The interest rate and amount of interest to be paid on the senior notes for each interest period will be determined by the calculation agent, which will initially be The Bank of New York Mellon Trust Company, N.A.; provided, however, that The Bank of New York Mellon Trust Company, N.A., neither in its role as calculation agent, trustee nor in any other capacity, will serve as our designee for purposes of the Benchmark or Benchmark Replacement (each as defined above) or in making the determinations of an effect of such Benchmark Transition Event. The Bank of New York Mellon Trust Company, N.A. is serving as the calculation agent; however, we may change the calculation agent at any time without notice, and The Bank of New York Mellon Trust Company, N.A. may resign as calculation agent at any time upon sixty (60) days' written notice to us. Promptly upon determination, we (or our designee) will inform the calculation agent and the trustee of the interest rate for the next interest period. None of the trustee, the calculation agent, our designee or we shall have any liability or responsibility for any information used in determining or calculating any interest rate. All determinations made by the calculation agent, us or our designee will, in the absence of manifest error, be conclusive for all purposes and binding on us and the holders of the senior notes. So long as Compounded SOFR is required to be determined with respect to the senior

S-25<br>

------

notes, there will at all times be a calculation agent. In the event that any then acting calculation agent shall be unable or unwilling to act, or that such calculation agent shall fail duly to establish Compounded SOFR for any interest period, or we propose to remove such calculation agent, we will appoint another calculation agent.

None of the trustee, the paying agent or the calculation agent will be under any obligation (i) to monitor, determine or verify the unavailability or cessation of SOFR or the SOFR Index, or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, adopt, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, adopt, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing. The trustee, the paying agent and the calculation agent shall be entitled to rely upon any determination or designation of any Benchmark Replacement (and any Benchmark Replacement Adjustment or Benchmark Replacement Conforming Changes, or other modifier), or other successor or replacement benchmark index, by us our or our designee.

None of the trustee, the paying agent or the calculation agent will be liable for (i) any inability, failure or delay on its part to perform any of its duties set forth in this prospectus supplement as a result of the unavailability of SOFR, the SOFR Index or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of this prospectus supplement and reasonably required for the performance of such duties or (ii) any failure or delay by us or our designee in performing our respective duties under the indenture or other transaction documents as a result of the unavailability of SOFR, or any other Benchmark Replacement described herein or the failure of a Benchmark Replacement to be adopted.

#### Agreement with Respect to the Benchmark Replacement
By its acquisition of the senior notes, each holder of the senior notes (including each holder of a beneficial interest in the senior notes) and, in the case of (ii) and (iii) below, we (i) acknowledges, accepts, consents and agrees to be bound by our or our designee's determination of a Benchmark Transition Event, a Benchmark Replacement Date, the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, including as may occur without any prior notice from us and without the need for us to obtain any further consent from such holder of the senior notes, (ii) will waive any and all claims, in law and/or in equity, against the trustee, the paying agent and the calculation agent or our designee for, agree not to initiate a suit against the trustee, the paying agent and the calculation agent or our designee in respect of, and agree that none of the trustee, the paying agent or the calculation agent or our designee will be liable for, the determination of or our failure or delay (including any failure to perform their duties as a result of our failure or delay) to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, and any losses suffered in connection therewith and (iii) will agree that none of the trustee, the paying agent or the calculation agent or our designee will have any obligation to determine, confirm or verify any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes (including any adjustments thereto), including in the event of any failure or delay by us to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes.

Except as set forth therein, all percentages resulting from any calculation of any interest rate for the senior notes will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts would be rounded to the nearest cent, with one-half cent being rounded upward.

#### Definitions
Capitalized terms used but not otherwise defined herein shall have the following meanings:

"Benchmark Replacement Adjustment" means the first alternative set forth in the order below that can be determined by us or our designee (in consultation with us) as of the Benchmark Replacement Date:

#### **TABLE OF CONTENTS**
recommended by the Relevant Governmental Body or (ii) determined by us or our designee (in consultation with us) in accordance with the method for calculating or determining such spread adjustment that has been selected or recommended by the Relevant Governmental Body, in each case for the applicable Unadjusted Benchmark Replacement;

(2)<br> if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; or

(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by us or our designee (in consultation with us) giving due consideration to industry-accepted spread adjustments (if any), or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate notes at such time. 

"Benchmark Replacement Date" means the earliest to occur of the following events with respect to the then- current Benchmark:

(1) in the case of clause (1) or (2) of the definition of "Benchmark Transition Event," the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or 

(2)<br> in the case of clause (3) of the definition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

"Benchmark Transition Event" means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(3)<br> a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

"Business Day" means 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.

"Corresponding Tenor" with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding Business Day adjustments) as the applicable tenor for the then-current Benchmark.

"ISDA Fallback Rate" means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

"ISDA Fallback Adjustment" means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions.

"Relevant Governmental Body" means the Federal Reserve and/or the NY Federal Reserve, or a committee officially endorsed or convened by the Federal Reserve and/or the NY Federal Reserve or any successor thereto.

"Relevant Rules" means, at any time, the laws, regulations, requirements, guidelines and policies relating to capital adequacy (including, without limitation, as to leverage, total loss absorbing capacity ("TLAC"), or regulatory long term debt requirements) then in effect in the U.S. and applicable to us from time to time and any regulations, requirements, guidelines and policies relating to capital adequacy adopted from time to time (whether or not such requirements, guidelines or policies are applied generally or specifically to us or to us and any of our holding or subsidiary companies or any subsidiary of any such holding company).

"Unadjusted Benchmark Replacement" means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

#### Ranking
The senior 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 non-banking 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 senior notes or to provide us with funds to pay our obligations on the senior notes, whether by dividends, distributions, loans or other payments. Our subsidiaries may, without notice or consent of the holders of the senior notes, incur additional debt and liabilities in the future, all of which would rank structurally senior to the senior notes. As of September 30, 2025, our subsidiaries had, in the aggregate, outstanding debt and other liabilities, including deposits, of approximately $187 billion. All of such debt and other liabilities would rank structurally senior to the senior notes in case of liquidation or otherwise. As of September 30, 2025, Huntington Bancshares Incorporated (parent company only) had approximately $6 billion of outstanding senior debt and approximately $1 billion of outstanding subordinated and junior subordinated debt.

#### Optional Redemption
On or after July 27, 2026 (180 days after the senior notes Issue Date) (or, if additional notes are issued, beginning 180 days after the issue date of such additional notes), and, prior to January 28, 2031 (one year prior to the senior notes Maturity Date (the "senior notes First Par Call Date")), we may redeem the senior notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the senior notes matured on the senior notes First Par Call Date) on a semi- annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the date of redemption, and 

(2) 100% of the principal amount of the senior notes to be redeemed, 

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On the senior notes First Par Call Date, we may redeem the senior notes, in whole but not in part, or on or after December 28, 2031 (one month prior to the senior notes Maturity Date), in whole or in part, at any time and from time to time, in each case at a redemption price equal to 100% of the principal amount of the senior notes being redeemed plus accrued and unpaid interest thereon to the redemption date. "Treasury Rate" means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

S-28<br>

------

#### **TABLE OF CONTENTS**
The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Federal Reserve), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Federal Reserve designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the senior notes First Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the senior notes First Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third Business Day preceding the redemption date H.15 TCM or any successor designation or publication is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the senior notes First Par Call Date. If there is no United States Treasury security maturing on the senior notes First Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the senior notes First Par Call Date, one with a maturity date preceding the senior notes First Par Call Date and one with a maturity date following the senior notes First Par Call Date, we shall select the United States Treasury security with a maturity date preceding the senior notes First Par Call Date. If there are two or more United States Treasury securities maturing on the senior notes First Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 5 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

In the case of a partial redemption, selection of the senior notes for redemption will be made pro rata, by lot or in accordance with the policies and procedures of the depositary. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the senior notes are held by DTC (or another depositary), the redemption of the senior notes shall be done in accordance with the policies and procedures of the depositary.

Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the senior notes or portions thereof called for redemption.

Neither the trustee nor the Calculation Agent shall be responsible for or have any responsibility to determine or make any calculations in connection with any redemption.

#### 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:

&nbsp;&nbsp;&nbsp;&nbsp;• we are the survivor in the merger, or the survivor, if not us, (1) is a corporation organized and validly existing under the laws of the United States, any state of the United States or the District of Columbia and (2) expressly assumes by supplemental senior indenture the due and punctual payment of the principal of and interest on all of the outstanding notes and the due and punctual performance and observance of all of the covenants and conditions to be performed by us contained in the senior indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• immediately after giving effect to the transaction and treating any indebtedness that becomes an obligation of ours or one of our subsidiaries as a result of the transaction, as having been incurred by us or the subsidiary at the time of the transaction, no covenant breach under the senior indenture, and no event which, after notice or the lapse of time, or both, would become a covenant breach, shall have occurred and be continuing;

&nbsp;&nbsp;&nbsp;&nbsp;• if, as a result of the transaction, our property or assets would be subject to a mortgage, pledge, lien, security interest or other encumbrance that would not be permitted under the senior indenture, we or such successor person, as the case may be, shall take steps to secure the senior notes equally and ratably with all indebtedness secured in the transaction; and

&nbsp;&nbsp;&nbsp;&nbsp;• we deliver to the trustee an officer's certificate and an opinion of counsel, each stating that such consolidation, merger or transfer of our properties and assets complies with the senior indenture and that all conditions precedent to such consolidation, merger or transfer of properties and assets have been complied with.

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 senior indenture.

The foregoing requirements do not apply in the case of merger, consolidation or sale of assets to one or more entities that are direct or indirect subsidiaries in which we or one or more subsidiaries owns more than 50% of the combined voting power. As a result, if we were to undertake such a transaction, such subsidiary or subsidiaries would not be required to assume our obligations under the senior notes and we would remain the sole obligor on the senior notes.

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 senior indenture providing for a put or increased interest or that would otherwise afford holders of the senior 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, 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 senior notes.* 

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

S-30<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• all taxes, assessments, and governmental charges levied or imposed upon us or any subsidiary of ours or upon our income, profits or property or that of any subsidiary of ours; and

&nbsp;&nbsp;&nbsp;&nbsp;• all lawful claims for labor, materials, and supplies which, if unpaid, might by law become a lien upon our property or any subsidiary of ours;

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 senior indenture, or with certain other terms, provisions or conditions with respect to the senior notes (except any such term, provision or condition which could not be amended without the consent of all holders of the senior 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 senior notes either waive compliance in that instance or generally waive compliance with that covenant, provision or condition. Unless the holders of the senior 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 senior indenture, directly or indirectly, to do any of the following:* 

&nbsp;&nbsp;&nbsp;&nbsp;• sell, assign, pledge, transfer, or otherwise dispose of, or permit to be issued, any shares of capital stock of a principal subsidiary bank or any securities convertible into or rights to subscribe to such capital stock, unless, after giving effect to that transaction and the shares to be issued upon conversion of such securities or exercise of such rights into that capital stock, we will own, directly or indirectly, at least 80% of the outstanding shares of each class of capital stock of that principal subsidiary bank; or

&nbsp;&nbsp;&nbsp;&nbsp;• pay any dividend in capital stock of a principal subsidiary bank or make any other distribution in capital stock of a principal subsidiary bank, unless the principal subsidiary bank to which the transaction relates, after obtaining any necessary regulatory approvals, unconditionally guarantees payment of the principal and interest on the senior notes.

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 senior indenture does not restrict the ability of the principal subsidiary bank to sell or dispose of assets. The foregoing covenant in the senior indenture, however, does not prohibit any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;• any dispositions or dividends made by us or any principal subsidiary bank acting in a fiduciary capacity for any person or entity other than us or any principal subsidiary bank or to us or any of our wholly-owned subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;• the merger or consolidation of a principal subsidiary bank with and into another principal subsidiary bank;

&nbsp;&nbsp;&nbsp;&nbsp;• the sale, assignment, pledge, transfer or other disposition of shares of voting stock of a principal subsidiary bank made by us or any subsidiary where:

&nbsp;&nbsp;&nbsp;&nbsp;• the sale, assignment, pledge, transfer or other disposition is made, in the minimum amount required by law, to any person for the purpose of the qualification of such person to serve as a director;

&nbsp;&nbsp;&nbsp;&nbsp;• the sale, assignment, pledge, transfer or other disposition is made in compliance with an order of a court or regulatory authority of competent jurisdiction or as a condition imposed by any such court or regulatory authority to the acquisition by us or any principal subsidiary bank, directly or indirectly, of any other corporation, trust or other entity;

&nbsp;&nbsp;&nbsp;&nbsp;• the sale, assignment, pledge, transfer or other disposition of voting stock or any other securities convertible into or rights to subscribe to voting stock of a principal subsidiary bank, so long as:

&nbsp;&nbsp;&nbsp;&nbsp;• any such transaction is made for fair market value as determined by our board of directors or the board of directors of the principal subsidiary bank disposing of such voting stock or other securities or rights; and

S-31<br>

------

&nbsp;&nbsp;&nbsp;&nbsp;• after giving effect to such transaction and to any potential dilution, we and our directly or indirectly wholly owned subsidiaries will own, directly or indirectly, at least 80% of the voting stock of such principal subsidiary bank;

&nbsp;&nbsp;&nbsp;&nbsp;• any of our principal subsidiary banks selling additional shares of voting stock to its stockholders at any price, so long as immediately after such sale, we own, directly or indirectly, at least as great a percentage of the voting stock of such subsidiary bank as we owned prior to such sale of additional shares; or

&nbsp;&nbsp;&nbsp;&nbsp;• a pledge made or a lien created to secure loans or other extensions of credit by a principal subsidiary bank subject to Section 23A of the Federal Reserve Act.

#### Events of Default, Notice and Waiver
Each of the following "Events of Default" set forth in the senior indenture will be applicable to senior debt securities issued on or after the senior notes Issue Date (including the senior notes):

&nbsp;&nbsp;&nbsp;&nbsp;• we fail for 30 days to pay any installment of interest payable on any debt security of a series of the senior notes (including the senior notes);

&nbsp;&nbsp;&nbsp;&nbsp;• we fail for 30 days to pay the principal of (or premium, if any, on) any debt security of a series of notes when due (including the senior notes); and

&nbsp;&nbsp;&nbsp;&nbsp;• certain events of bankruptcy, insolvency or reorganization of us (but not our principal banking subsidiary) occur.

Subject to the following paragraph, for senior debt securities issued on or after the senior notes Issue Date, including the senior notes, no other defaults under or breaches of the senior base indenture or any senior debt securities, including the senior notes, will result in an Event of Default, whether after notice, the passage of time or otherwise and therefore none of such other events (even if constituting a covenant breach) will result in a right of acceleration of the payment of the outstanding principal amount of such senior debt securities, including the senior notes. For example, the occurrence of events relating to the bankruptcy, insolvency or reorganization of any principal subsidiary bank will not directly constitute an Event of Default under the senior indenture, although it would constitute an event of default under the existing senior debt securities issued prior to the senior notes Issue Date. However, certain events may give rise to a covenant breach, as described below under "—Covenant Breaches."

We may change, eliminate or add to the events of default with respect to any particular series of senior debt securities, as indicated in the applicable prospectus supplement relating to such series. For the avoidance of doubt, the only Events of Default with respect to the senior notes are those set forth above.

If a continuing Event of Default under the senior indenture, other than a bankruptcy Event of Default, occurs and continues with respect to the senior notes, the trustee or the holders of not less than 25% of the total principal amount of the senior notes may declare immediately due and payable the principal amount of such notes.

If an Event of Default occurs as a result of our bankruptcy, insolvency or reorganization, the principal amount of the senior 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 senior 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 senior notes may rescind and annul such declaration and its consequences if:

&nbsp;&nbsp;&nbsp;&nbsp;• we deposit with the trustee all required payments of the principal of, and interest on the senior notes (and, to the extent lawful, interest on overdue installments of interest) plus certain fees, expenses, disbursements and advances of the trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;• all Events of Default, other than the non-payment of accelerated principal of the senior notes, have been cured or waived as provided in the senior indenture.

S-32<br>

------

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

&nbsp;&nbsp;&nbsp;&nbsp;• our failure to pay the principal of or interest on such notes; or

&nbsp;&nbsp;&nbsp;&nbsp;• a default relating to a covenant or provision contained in the senior indenture that cannot be modified or amended without the consent of the holders of each outstanding note.

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

The senior indenture provides that no holder of the senior notes may institute a proceeding with respect to the senior indenture or for any remedy under the senior 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:

&nbsp;&nbsp;&nbsp;&nbsp;• it has received a written request to institute proceedings in respect of an Event of Default from the holders of not less than 25% in principal amount of the senior notes, as well as an offer of indemnity satisfactory to the trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;• no direction inconsistent with such written request has been given to the trustee during that 60-day period by the holders of a majority in principal amount of the senior notes.

#### Covenant Breaches
Any one of the following events constitutes a "covenant breach" under the senior base indenture with respect to any series of senior debt securities issued on or after the date the senior notes are issued, including the senior notes:

&nbsp;&nbsp;&nbsp;&nbsp;• we default in the performance of or breach any other covenant or agreement we made in the senior indenture with respect to the senior notes which default or breach has continued for 90 days after written notice as provided for in accordance with the senior indenture by the trustee or by the holders of at least 25% in principal amount of the senior notes; and

&nbsp;&nbsp;&nbsp;&nbsp;• we default under a bond, debenture, note or other evidence of indebtedness for money borrowed by us that has a principal amount outstanding that is more than $50 million (other than non-recourse indebtedness) under the terms of the instrument under which the indebtedness is issued or secured, which default has caused the indebtedness to become due and payable earlier than it would otherwise have become due and payable, and the acceleration has not been rescinded or annulled, or the indebtedness is discharged, or there is deposited in trust enough money to discharge the indebtedness, within 30 days after written notice was provided to us by the trustee or the holders of at least 25% in principal amount of the senior notes in accordance with the senior indenture.

Subject to provisions in the senior indenture relating to the trustee's duties in case of Events of Default (which does not include covenant breaches), the trustee is not under an obligation to exercise any of its rights or powers under the senior indenture at the request or direction of any holders of the senior notes, unless the holders of the senior 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 senior 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 senior 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 senior indenture and, in the event of any non-compliance, specifying such non-compliance and the nature and status of the non-compliance.

#### **TABLE OF CONTENTS**

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

&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity or due date of the principal of or interest payable on the senior notes or change any place of payment where or the currency in which such principal and interest is payable;

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of or the rate or amount of interest on the senior notes;

&nbsp;&nbsp;&nbsp;&nbsp;• impair the right to institute suit for the enforcement of any payment on or with respect to the senior notes (or, in the case of redemption, on or after the redemption date);

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage of the holders of the senior notes necessary to modify or amend the senior indenture or to waive compliance with certain provisions thereof or certain defaults and consequences thereunder; or

&nbsp;&nbsp;&nbsp;&nbsp;• modify any of the foregoing provisions or any of the provisions relating to the waiver of certain past defaults or certain covenants with respect to the senior notes, except to increase the required percentage to effect such action or to provide that certain other provisions may not be modified or waived without the consent of the holders of the senior notes.

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

&nbsp;&nbsp;&nbsp;&nbsp;• to evidence the succession of another person pursuant to the terms of the senior indenture to us as obligor under the senior indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• to add to the covenants for the benefit of the holders of the senior notes or to surrender any right or power conferred upon us in the senior indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• to add Events of Default for the benefit of the holders of the senior notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to add or change any provisions of the senior indenture to facilitate the issuance of notes, or to permit or facilitate the issuance of notes in uncertificated form, provided that such action shall not adversely affect the interests of the holders of the senior notes in any material respect;

&nbsp;&nbsp;&nbsp;&nbsp;• to add, change or eliminate any provisions of the senior indenture, provided that any such addition, change or elimination shall:

&nbsp;&nbsp;&nbsp;&nbsp;• neither (a) apply to any note created prior to the execution of the supplemental senior indenture effectuating such addition, change or elimination and entitled to the benefit of such provision, nor (b) modify the rights of the holder of such note with respect to such provision; or

&nbsp;&nbsp;&nbsp;&nbsp;• become effective only when there are no notes outstanding under the senior indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• to secure the senior notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to evidence and provide for the acceptance or appointment of a successor trustee with respect to the senior notes or facilitate the administration of the trusts under the senior indenture by more than one trustee;

&nbsp;&nbsp;&nbsp;&nbsp;• cure any ambiguity, defect or inconsistency in the senior indenture or to make any other provisions with respect to matters or questions arising under the senior indenture, provided that in each case, such provisions shall not adversely affect the interests of the holders of the senior notes in any material respect;

&nbsp;&nbsp;&nbsp;&nbsp;• to qualify, or maintain qualification of, the senior indenture under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"); and

&nbsp;&nbsp;&nbsp;&nbsp;• to implement any benchmark transition provisions after a Benchmark Transition Event or its related Benchmark Replacement date have occurred (or in anticipation thereof).

#### Discharge, Defeasance and Covenant Defeasance
Under the senior indenture, we may discharge certain obligations to holders of the senior 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 payable within one year. We can discharge these obligations by irrevocably depositing with the trustee funds

S-34<br>

------

#### **TABLE OF CONTENTS**
in United States dollars in an amount sufficient to pay the entire indebtedness on the senior notes, including the principal of and interest payable on the senior notes to the date of the deposit, if the senior notes have become due and payable, or to the senior notes Maturity Date, if the senior notes have not yet become due and payable.

We may also elect either of the following:

&nbsp;&nbsp;&nbsp;&nbsp;• to be defeased and discharged from any and all obligations with respect to the senior notes ("legal defeasance"), except our obligations, including but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;• to register the transfer or exchange of the senior notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to replace temporary or mutilated, destroyed, lost or stolen notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to maintain an office or agency for the senior notes; and

&nbsp;&nbsp;&nbsp;&nbsp;• to hold moneys for payment in trust; or

&nbsp;&nbsp;&nbsp;&nbsp;• to be defeased and discharged from certain of our obligations described under "—Certain Covenants," including "—Certain Covenants—Sale or Issuance of Capital Stock in Principal Subsidiary Bank," with respect to the senior notes and our obligations described under "—Merger, Consolidation or Sale of Assets" or, to the extent permitted by the terms of the senior notes, our obligations with respect to any other covenant ("covenant defeasance").

If we choose to defease and discharge our obligations under the covenants with respect to the senior 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 senior 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 senior 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:

&nbsp;&nbsp;&nbsp;&nbsp;• we have delivered to the trustee an opinion of counsel to the effect that the holders of the senior notes will not recognize income, gain or loss for United States federal income tax purposes as a result of the legal defeasance or covenant defeasance described in the previous paragraphs and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the legal defeasance or covenant defeasance had not occurred. In the case of legal defeasance, the opinion of counsel must refer to and be based upon a ruling of the IRS or a change in applicable United States federal income tax laws occurring after the date of the senior indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• we have delivered to the trustee an opinion of counsel to the effect that, after the 120th day following the deposit or, if longer, after the expiration of the longest preference period applicable to us under federal or state law in respect of such deposit, the trust funds deposited with the trustee to pay the principal of and interest on the senior notes on the relevant scheduled due dates will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally;

&nbsp;&nbsp;&nbsp;&nbsp;• such legal defeasance or covenant defeasance, as the case may be, does not result in, or constitute, a breach or violation of the senior indenture or any other material agreement which we are a party to or obligated under; and

&nbsp;&nbsp;&nbsp;&nbsp;• no Event of Default, or event that with notice or lapse of time or both will be an Event of Default, has occurred and is continuing with respect to the senior notes.

#### Subordinated Notes

#### General
We will issue $750,000,000 aggregate principal amount of 5.605% Fixed-to-Fixed Rate Subordinated Notes due 2041 (the "subordinated notes"). The subordinated notes will be a series of our subordinated debt securities. We will issue the subordinated notes under a subordinated debt indenture, dated as of December 29, 2005, between us and The Bank of New York Mellon Trust Company, N.A., as successor to JPMorgan Chase Bank, as trustee, as amended or supplemented from time to time and as amended by a fourth supplemental subordinated indenture, to be dated as of January 28, 2026, each between us and the trustee. Throughout this section of the description of notes, we refer to both the subordinated debt indenture as the "subordinated base indenture" and the subordinated base

S-35<br>

------

#### **TABLE OF CONTENTS**
indenture and supplemental subordinated indentures together as the "subordinated indenture." The following description of the subordinated 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 subordinated indenture, it is our intent that those sections or defined terms will be incorporated by reference in this prospectus supplement.

The subordinated notes will mature at 100% of their principal amount on January 28, 2041 (the "subordinated notes Maturity Date") unless earlier redeemed or repaid.

As described below under "—Subordination," the subordinated notes will be unsecured and subordinated in right of payment to the payment of our existing and future Senior Debt (as defined in the subordinated indenture), will rank equal in right of payment to all of our existing and future indebtedness ranking on a parity with the subordinated notes, and will be senior to any obligation of ours that ranks junior and not equally with or prior to the subordinated notes, including our junior subordinated debentures or indentures, as applicable, issued to our statutory trusts (which debentures rank junior to the subordinated notes). The subordinated notes are obligations of Huntington only and are not guaranteed by any of our subsidiaries. As a result, the subordinated notes will be structurally subordinated to the liabilities of our subsidiaries, including the Bank. The subordinated notes will not be entitled to any sinking fund.

Since we are a holding company, our rights and the rights of our creditors, including holders of the subordinated 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 are likely to 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 subordinated notes will be subject to defeasance under the conditions described below in "—Discharge, Defeasance and Covenant Defeasance."

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

The subordinated 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 subordinated notes on any securities exchange.

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 subordinated notes will bear interest (i) from and including January 28, 2026 (the "subordinated notes Issue Date") to, but excluding, January 28, 2036 (the "subordinated notes Reset Date"), or to, but excluding, the date of earlier redemption, at a fixed rate of 5.605% per annum and (ii) during the period from and including the subordinated notes Reset Date to, but excluding, the subordinated notes Maturity Date, or to, but excluding, the date of earlier redemption, at a rate per annum that will be the Five-year U.S. Treasury Rate as of the day falling two Business Days (as defined in the subordinated indenture) prior to the subordinated notes Reset Date (the "subordinated notes Reset Determination Date"), plus 1.350% per annum.

We will pay interest on the subordinated notes semiannually in arrears, on January 28 and July 28 of each year, commencing on July 28, 2026 and ending on the subordinated notes Maturity Date or date of earlier redemption or repayment.

Interest on the subordinated notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. If an interest payment date, the subordinated notes Maturity Date, or any date of redemption or repayment falls on a day that is not a Business Day, we will postpone the payment of interest or principal, as applicable, to the next succeeding Business Day, but the payment made on such date will be treated as having been made on the date that the payment was first due and the holders of the subordinated notes will not be entitled to any further interest or other payments with respect to such postponement.

#### **TABLE OF CONTENTS**
The interest payable on the subordinated notes on any interest payment date will, subject to certain exceptions, be paid to the person in whose name the subordinated notes are registered at the close of business on the fifteenth calendar day preceding the applicable interest payment date, whether or not a Business Day.

The "*Five-year U.S. Treasury Rate*" means, as of the subordinated notes Reset Determination Date, the average (rounded to three decimal places) of the yields on actively traded U.S. treasury securities adjusted to constant maturity, for five-year maturities, for the five Business Days immediately preceding the subordinated notes Reset Determination Date appearing under the caption "Treasury Constant Maturities (Nominal)" in the most recently published statistical release designated H.15 or any successor publication which is published by the Federal Reserve as of 5:00 p.m. (Eastern Time) as of any date of determination, as determined by the calculation agent in its sole discretion. If no calculation is provided as described above, then the calculation agent, after consulting such sources as it deems comparable to the foregoing calculations, or any such source as it deems reasonable from which to estimate the five-year treasury rate, shall determine the Five-year U.S. Treasury Rate in its sole discretion, provided that if the calculation agent determines there is an industry-accepted successor Five-year U.S. Treasury Rate, then the calculation agent shall use such successor rate. If the calculation agent, in its sole discretion, determines that there is no reasonable comparable source, then the Five-year U.S. Treasury Rate on the Reset Determination Date will be 4.255%, which is the initial fixed interest rate minus 1.350% per annum.

"*H.15*" means the daily statistical release designated as such, or any successor publication, published by the Federal Reserve.

Unless we have delivered notice of redemption of all outstanding subordinated notes, with such redemption to occur on the subordinated notes Reset Date, we will appoint a calculation agent (which in no event shall be the trustee or any paying agent unless otherwise agreed to in writing) with respect to the subordinated notes prior to the subordinated notes Reset Determination Date. The Five-year U.S. Treasury Rate will be determined by the calculation agent on the subordinated notes Reset Determination Date. The calculation agent will notify us within one Business Day of the interest rate from and after the subordinated notes Reset Date. We shall then promptly notify the trustee in writing within five Business Days of such interest rate. We or our affiliate may assume the duties of the calculation agent. Any determination, decision or election that may be made by the Issuer or the calculation agent pursuant to the provisions described in this prospectus, including any determination with respect to a rate, will be conclusive and binding absent manifest error, may be made in the Issuer's or the calculation agent's sole discretion, and, notwithstanding anything to the contrary in the documentation relating to the subordinated notes, shall become effective without consent from any other party. The calculation agent's determination of any interest rate will be on file at our principal offices, will be made available to any holder of subordinated notes upon request and will be final and binding in the absence of manifest error.

Interest will be payable by wire transfer in immediately available funds in U.S. dollars at the office of the paying agent or, in the event the subordinated notes are not represented by a global note, at the office or agency of the Issuer maintained for such purpose in Columbus, Ohio.

Neither the trustee nor any paying agent will have any obligation as calculation agent or for making any determinations to be made by the calculation agent as described above. The trustee and paying agent may conclusively rely on any calculation made by the calculation agent without independent verification and shall have no liability or responsibility for any calculations or any information in connection with such calculations.

#### Subordination
Our obligation to make any payment on account of the principal and interest on the subordinated notes will be expressly subordinate and junior in right of payment and liquidation to the prior payment in full in cash of all of our Senior Debt. "Senior Debt" is defined in the subordinated indenture to mean (other than obligations pursuant to the subordinated base indenture, including the subordinated notes) all of our (and not our subsidiaries'):

&nbsp;&nbsp;&nbsp;&nbsp;• indebtedness for borrowed or purchased money, whether or not evidenced by bonds, debentures, notes, or other written instruments, including obligations incurred in connection with the acquisition of property, assets or businesses;

&nbsp;&nbsp;&nbsp;&nbsp;• capital lease obligations;

&nbsp;&nbsp;&nbsp;&nbsp;• obligations arising from off-balance sheet guarantees and direct credit substitutes, including under letters of credit, bankers' acceptances or similar facilities issued for our account;

S-37<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• obligations issued or assumed as the deferred purchase price for property or services, including all obligations under master lease transactions pursuant to which we have agreed to be treated as owner of the subject property for U.S. federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;• obligations with respect to derivative products, including securities contracts, commodity contracts, interest rate and currency swap agreements, currency hedge, exchange or similar agreements, cap, floor, and collar agreements, currency spot and forward contracts, and other similar agreements or arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;• guarantees, endorsements (other than by endorsement of negotiable instruments for collection in the ordinary course of business), and other similar contingent obligations in respect of obligations of others of a type described in the preceding bullets, whether or not classified as a liability on a balance sheet prepared in accordance with accounting principles generally accepted in the United States; and

&nbsp;&nbsp;&nbsp;&nbsp;• obligations to our other general creditors;

in each case, whether outstanding on the date that we entered into the subordinated indenture or arising after that time.

Senior Debt will not include: (i) our capital stock, including our preferred stock, or depositary shares representing our stock, (ii) our obligations to our subsidiaries or to any person with respect to which we become a subsidiary, and (iii) all indebtedness that (a) expressly states that it is junior to or ranks equally in right of payment with the subordinated notes, (b) is identified as junior to, or equal in right of payment with, the subordinated notes in any board resolution establishing such indebtedness or in any supplemental subordinated indenture and (c) our junior subordinated debentures or indentures, as applicable, issued to our statutory trusts (which rank junior to the subordinated notes) that are our obligations.

Senior Debt will continue to be Senior Debt and entitled to the benefits of the subordination provisions of the subordinated indenture irrespective of any amendment, modification, or waiver of any term of Senior Debt or extension or renewal of Senior Debt.

In the event of any insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment of debt, composition, or other similar proceeding relating to Huntington or its property, any proceeding for the liquidation, dissolution, or other winding up of Huntington, whether voluntary or involuntary and whether or not involving insolvency, bankruptcy or receivership proceedings, any assignment by Huntington for the benefit of creditors or any other marshalling of the assets of Huntington, all of our obligations to holders of our Senior Debt will be entitled to be paid in full before any payment or distribution, whether in cash, securities or other property, can be made on account of the principal or interest on the subordinated notes. Only after payment in full of all amounts owing with respect to Senior Debt will the holders of the subordinated notes, together with the holders of any of our obligations ranking on a parity with the subordinated notes, be entitled to be paid from our remaining assets the amounts due and owing on account of unpaid principal of and interest on the subordinated notes.

In the event and during the continuation of any default in the payment of the principal of or any premium or interest on any Senior Debt beyond any applicable grace period with respect to such Senior Debt, or in the event that any event of default with respect to any Senior Debt shall have occurred and be continuing permitting the holders of such Senior Debt (or the trustee on behalf of the holders of such Senior Debt) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived or shall have ceased to exist and such acceleration shall have been rescinded or annulled, or in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default, then no payment shall be made by Huntington on account of the principal of or interest on the subordinated notes or on account of the purchase or other acquisition of any subordinated notes.

If we violate the subordinated indenture by making a payment or distribution to holders of the subordinated notes before we have paid all Senior Debt in full, then such holders of the subordinated notes will have to pay or transfer the payments or distributions to the trustee in bankruptcy, receivership or liquidation, or other person distributing our assets for payment of Senior Debt.

By reason of the above subordination in favor of the holders of our Senior Debt, in the event of our bankruptcy or insolvency, holders of our Senior Debt may receive more, ratably, and holders of the subordinated notes may receive less, ratably, than our other creditors.

S-38<br>

------

In addition, the subordinated notes may be fully subordinate to interests held by the U.S. government if we enter into a receivership, insolvency, liquidation, or similar proceeding, including a proceeding under the "orderly liquidation authority" provisions of the Dodd-Frank Act.

**The subordinated notes do not contain any limitation on the amount of Senior Debt or other obligations ranking senior to, pari passu with or junior to the indebtedness evidenced by the subordinated notes that may be hereafter incurred by Huntington or its subsidiaries.** 

With respect to the assets of a subsidiary of Huntington, creditors of Huntington (including holders of the subordinated notes) are structurally subordinated to the prior claims of creditors of such subsidiary, except to the extent that Huntington may be a creditor with recognized claims against such subsidiary.

The subordinated notes will not be guaranteed by any of our subsidiaries. Our subsidiaries may, without notice or consent of the holders of the subordinated notes, incur additional debt or liabilities in the future, all of which would rank structurally senior to the subordinated notes. Huntington may from time to time, without notice or consent of the holders of the subordinated notes, incur additional indebtedness ranking equally with the subordinated notes, as well as junior subordinated indebtedness ranking junior to the subordinated notes.

As of September 30, 2025, we had approximately $8.7 billion of Senior Debt, approximately $4.1 billion of indebtedness ranking on a parity with the subordinated notes and approximately $4.5 billion of indebtedness ranking junior to the subordinated notes, including our junior subordinated debentures or indentures, as applicable, issued to our statutory trusts. As of that date, we had a total consolidated indebtedness of $17.3 billion, including $10.4 billion of indebtedness of our subsidiaries.

#### Optional Redemption
On at least 5 days but no more than 60 days prior written notice delivered to the registered holders of the subordinated notes, we may redeem the subordinated notes in whole, but not in part, during the three months prior to and including the subordinated notes Reset Date, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, at a redemption price equal to 100% of the aggregate principal amount of the subordinated notes, plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date. We shall provide written notice to the trustee of any redemption at least 15 days prior to the redemption date (unless a shorter notice is satisfactory to the trustee).

We may also redeem the subordinated notes, in whole or in part, or on or after July 28, 2040 (six months prior to the subordinated notes Maturity Date), at any time and from time to time, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, at a redemption price equal to 100% of the principal amount of the subordinated notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

The subordinated notes may not otherwise be redeemed prior to the subordinated notes Maturity Date, except that on at least 5 days but no more than 60 days prior written notice delivered to the registered holders of the subordinated notes, we may also at our option and subject to prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, redeem the subordinated notes in whole, but not in part, at a redemption price equal to 100% of the principal amount of the subordinated notes being redeemed plus accrued and unpaid interest to, but excluding, the date of redemption, within 90 days after the occurrence of:

&nbsp;&nbsp;&nbsp;&nbsp;• a "Tax Event," defined in the subordinated indenture to mean the receipt by us of an opinion of independent tax counsel to the effect that as a result of (a) an amendment to or change (including any announced prospective amendment or change) in any law or treaty, or any regulation thereunder, of the United States or any of its political subdivisions or taxing authorities; (b) a judicial decision, administrative action, official administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an "administrative or judicial action"); or (c) an amendment to or change in any official position with respect to, or any interpretation of, an administrative or judicial action or a law or regulation of the United States that differs from the previously generally accepted position or interpretation in each case, which change or amendment becomes effective or which administrative or judicial action is announced on or after the subordinated notes Issue Date, there is more than an insubstantial risk that interest payable by us on the subordinated notes is not, or, within 90 days after the date of such opinion, will not be, deductible by us, in whole or in part, for U.S. federal income tax purposes;

S-39<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• a "Tier 2 Capital Event," defined in the subordinated indenture to mean our good faith determination that, as a result of (a) any amendment to, or change in, the laws, rules or regulations of the United States (including, for the avoidance of doubt, any agency or instrumentality of the United States, including the Federal Reserve and other federal bank regulatory agencies) or any political subdivision of or in the United States that is enacted or becomes effective after the subordinated notes Issue Date; (b) any proposed change in those laws, rules or regulations that is announced or becomes effective after the subordinated notes Issue Date; or (c) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules, regulations, policies or guidelines with respect thereto that is announced after the subordinated notes Issue Date, there is more than an insubstantial risk that we will not be entitled to treat the subordinated notes then outstanding as "Tier 2 Capital" (or its equivalent) for purposes of the capital adequacy rules or regulations of the Federal Reserve (or, as and if applicable, the capital adequacy rules or regulations of any successor appropriate federal banking agency) as then in effect and applicable to us, for so long as any subordinated notes are outstanding; or

&nbsp;&nbsp;&nbsp;&nbsp;• Huntington becoming required to register as an investment company pursuant to the 1940 Act.

If we elect to redeem the subordinated notes, we will provide notice by first class mail, postage prepaid, or electronic transmission, addressed to the holders of record (which, in the case of registered global notes, will be DTC or its nominee or a nominee of Euroclear and Clearstream) of the subordinated notes. Such mailing or transmission will be at least 5 days and not more than 60 days before the redemption date. Each notice of redemption will state:

&nbsp;&nbsp;&nbsp;&nbsp;• the redemption date;

&nbsp;&nbsp;&nbsp;&nbsp;• the redemption price;

&nbsp;&nbsp;&nbsp;&nbsp;• "CUSIP" or "ISIN" number of the subordinated notes;

&nbsp;&nbsp;&nbsp;&nbsp;• that on the redemption date the redemption price will become due and payable upon each subordinated note, and that interest thereon will cease to accrue on and after the date of redemption; and

&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where the subordinated notes are to be surrendered for payment of the redemption price.

If the subordinated notes are to be redeemed, the redemption price payable to the holder of any subordinated 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 subordinated notes. If money sufficient to pay the redemption price of, and any accrued interest on, the subordinated notes on the redemption date is deposited with our paying agent on or before the redemption date and certain other conditions are satisfied, then on and after the redemption date, interest will cease to accrue on the subordinated notes and the subordinated notes will cease to be outstanding.

Notwithstanding any of the foregoing, installments of interest on the subordinated notes that are due and payable on an interest payment date falling on or prior to the redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date in accordance with the subordinated notes and the subordinated indenture.

Under the Federal Reserve's current risk-based capital regulations, any redemption of the subordinated notes will be subject to the prior approval of the Federal Reserve. In addition, prior to exercising our option to redeem the subordinated notes, or immediately thereafter, we will be required to either replace the redeemed subordinated notes with an equivalent amount of a financial instrument that meets the Federal Reserve's regulatory capital criteria, or demonstrate to the satisfaction of the Federal Reserve that following redemption, or immediately thereafter, we would continue to hold an amount of capital that is commensurate with Huntington's risk.

The subordinated notes will not be subject to repayment at the option of the holder at any time prior to the subordinated notes Maturity Date 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:

&nbsp;&nbsp;&nbsp;&nbsp;• we are the survivor in the merger, or the survivor, if not us, (1) is a person (as defined in the subordinated indenture) organized and validly existing under the laws of the United States, any state of the United

S-40<br>

------

#### **TABLE OF CONTENTS**
States or the District of Columbia and (2) expressly assumes by supplemental subordinated indenture the due and punctual payment of the principal of and interest on all of the outstanding subordinated notes and the due and punctual performance and observance of all of the covenants and conditions to be performed by us contained in the subordinated indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• immediately after giving effect to the transaction, no event of default (as described below) under the subordinated indenture, and no event which, after notice or the lapse of time, or both, would become an event of default, shall have occurred and be continuing; and

&nbsp;&nbsp;&nbsp;&nbsp;• other conditions described in the subordinated indenture are met.

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 subordinated 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 subordinated indenture providing for a put or increased interest or that would otherwise afford holders of the subordinated 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.

This covenant would not apply to the direct or indirect conveyance or transfer of all or any portion of the stock, assets or liabilities of any of our wholly owned subsidiaries to us or our other wholly owned subsidiaries.

#### Waiver of Certain Covenants
We may choose not to comply with any term, provision or condition of certain covenants contained in the subordinated indenture, or with certain other terms, provisions or conditions with respect to the subordinated notes (except any such term, provision or condition which could not be amended without the consent of all holders of the subordinated 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 subordinated notes either waive compliance in that instance or generally waive compliance with that covenant, provision or condition. Unless the holders of the subordinated 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.

#### Events of Default; Limitation on Suits
Under the subordinated indenture, an event of default will occur with respect to the subordinated notes only (1) if a court enters an order in an involuntary bankruptcy or insolvency proceeding of Huntington that continues unstayed and in effect for a period of 60 consecutive days or (2) if Huntington commences a bankruptcy or insolvency proceeding or consents to the entry of an order in an involuntary bankruptcy or insolvency proceeding or (3) if Huntington is placed into receivership in a proceeding under the "orderly liquidation authority" provisions of the Dodd-Frank Act.

If an event of default occurs and is continuing, the principal amount of and accrued and unpaid interest on the subordinated notes shall become immediately due and payable. The foregoing provision would, in the event of the bankruptcy, insolvency or receivership involving Huntington, be subject as to enforcement to the broad equity powers of a federal bankruptcy court and to the determination by that court of the nature and status of the payment claims of the holders of the subordinated notes. At any time after a declaration of acceleration with respect to the subordinated notes has been made, but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in principal amount of outstanding subordinated notes and other affected series of securities issued under the subordinated indenture (we refer to the subordinated notes and such other securities as the "Securities"), may rescind and annul the acceleration but only if certain conditions have been satisfied.

**There is no right of acceleration in the case of a default in the payment of principal of or interest on the subordinated notes or in our performance of any other obligation under the subordinated notes or the subordinated indenture. If we default in our obligation to pay any interest on the subordinated notes when**

#### **TABLE OF CONTENTS**
**due and payable and such default continues for a period of 30 days, or if we default in our obligation to pay the principal amount due upon maturity, or if we breach any covenant or agreement contained in the subordinated indenture, then the trustee may, subject to certain limitations and conditions, seek to enforce its rights and the rights of the holders of subordinated notes of the performance of any covenant or agreement in the subordinated indenture.** 

The subordinated indenture provides that, subject to the duty of the trustee upon the occurrence and continuance of an event of default to act with the required person standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the subordinated indenture at the request or direction of any of the holders of subordinated notes unless such holders shall have offered to the trustee reasonable indemnity or security against the costs, expenses and liabilities which may be incurred by it in complying with such request or direction. Subject to certain provisions, the holders of a majority in principal amount of the outstanding subordinated notes will have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the subordinated notes.

No holder of subordinated notes shall have any right to institute any proceeding, judicial or otherwise, with respect to the subordinated debt indenture, or for the appointment of a receiver or trustee, or for any other remedy under the subordinated indenture, unless:

&nbsp;&nbsp;&nbsp;&nbsp;• such holder has previously given written notice to the trustee of a continuing event of default with respect to the subordinated notes;

&nbsp;&nbsp;&nbsp;&nbsp;• the holders of not less than 25% in principal amount of the subordinated notes shall have made written request to the trustee to institute proceedings in respect of such event of default in its own name as trustee under the subordinated indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• such holder or holders have offered to the trustee indemnity against the costs, expenses, and liabilities to be incurred in complying with such request;

&nbsp;&nbsp;&nbsp;&nbsp;• the trustee for 60 days after its receipt of such notice, request, and offer of indemnity has failed to institute any such proceeding; and

&nbsp;&nbsp;&nbsp;&nbsp;• no direction inconsistent with such written request has been given to the trustee during such 60-day period by the holders of a majority in principal amount of the outstanding subordinated notes.

In any event, the subordinated indenture provides that no one or more of such holders shall have any right under the subordinated indenture to affect, disturb or prejudice the rights of any other holder, or to obtain priority or preference over any of the other holders or to enforce any right under the subordinated indenture, except in the manner provided in the subordinated indenture and for the equal and ratable benefit of all holders of subordinated notes.

#### Modification and Waiver
The subordinated indenture provides that we and the trustee may modify or amend the subordinated indenture with or, in certain cases, without the consent of the holders of a majority in principal amount of outstanding subordinated notes and other affected Securities; provided, however, that any modification or amendment may not, without the consent of the holder of each outstanding Security affected thereby:

&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of the principal of, or any installment of interest on, any Security;

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount or rate of interest of any Security;

&nbsp;&nbsp;&nbsp;&nbsp;• change the place of payment where any Security or any interest is payable;

&nbsp;&nbsp;&nbsp;&nbsp;• impair the right to institute suit for the enforcement of any payment on or after its stated maturity;

&nbsp;&nbsp;&nbsp;&nbsp;• modify the provisions of the subordinated indenture with respect to the subordination of the Securities in a manner adverse to the holders of the Securities; or

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in principal amount of the outstanding Securities the consent of whose holders is required for any supplemental subordinated indenture, or the consent of whose holders is required for any waiver of compliance with the provisions of or defaults under the subordinated indenture and the consequences thereof under the subordinated indenture.

S-42<br>

------

#### **TABLE OF CONTENTS**
In addition, the holders of a majority in principal amount of the outstanding subordinated notes may, on behalf of all holders of subordinated notes, waive compliance by us with certain terms, conditions and provisions of the subordinated indenture, as well as any past default and/or the consequences of default, other than any default in the payment of principal or interest or any breach in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding Security of the affected series. In connection with any modification, waiver or amendment of the subordinated indenture, we shall provide the trustee with the required documentation under the subordinated indenture.

#### Discharge, Defeasance and Covenant Defeasance
Under the subordinated indenture, we may discharge certain obligations to holders of the subordinated 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 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 subordinated notes, including the principal of and interest payable on the subordinated notes to the date of the deposit, if the subordinated notes have become due and payable, or to the subordinated notes Maturity Date, if the subordinated notes have not yet become due and payable.

We may also elect either of the following:

&nbsp;&nbsp;&nbsp;&nbsp;• to be defeased and discharged from any and all obligations with respect to the subordinated notes ("legal defeasance"), except certain of our obligations, including but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;• to register the transfer or exchange of the subordinated notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to replace temporary or mutilated, destroyed, lost or stolen subordinated notes;

&nbsp;&nbsp;&nbsp;&nbsp;• to maintain an office or agency for the subordinated notes; and

&nbsp;&nbsp;&nbsp;&nbsp;• to hold moneys for payment in trust; or

&nbsp;&nbsp;&nbsp;&nbsp;• to be defeased and discharged from certain of our obligations described under "—Waiver of Certain Covenants" and our obligations described under "—Merger, Consolidation or Sale of Assets" or, to the extent permitted by the terms of the subordinated notes, our obligations with respect to any other covenant ("covenant defeasance").

If we choose to defease and discharge our obligations under the covenants with respect to the subordinated notes, we will not have any obligations with respect to such covenants and neither the trustee nor the holders of the subordinated notes will have any rights with respect to such covenants. 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 subordinated 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:

&nbsp;&nbsp;&nbsp;&nbsp;• we have delivered to the trustee an opinion of counsel to the effect that the holders of the subordinated notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the legal defeasance or covenant defeasance described in the previous paragraphs and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the legal defeasance or covenant defeasance had not occurred. In the case of legal defeasance, the opinion of counsel must refer to and be based upon a ruling of the IRS or a change in applicable U.S. federal income tax laws occurring after the date of the subordinated indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;• no event of default, or event that with notice or lapse of time or both will be an event of default, has occurred and is continuing with respect to the subordinated notes.

#### Senior Notes and Subordinated Notes

#### Same-Day Settlement and Payment
Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC Participants (as defined below) 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.

#### **TABLE OF CONTENTS**

#### Trustee
The Bank of New York Mellon Trust Company, N.A. will act as trustee for the notes. Amounts owed to the trustee in connection with the subordinated notes will not be treated as subordinated indebtedness. 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 indentures 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 indentures. 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 indentures, 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.

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

#### Governing Law
The indentures and the notes are governed by and will be construed in accordance with the laws of the State of New York.

#### 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, 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.

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.

S-45<br>

#### **TABLE OF CONTENTS**
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 indentures 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:

&nbsp;&nbsp;&nbsp;&nbsp;• will not be entitled to have such global security certificates or the notes represented by these certificates registered in their names;

&nbsp;&nbsp;&nbsp;&nbsp;• will not receive or be entitled to receive physical delivery of securities certificates in exchange for beneficial interests in global security certificates; and

&nbsp;&nbsp;&nbsp;&nbsp;• will not be considered to be owners or holders of the global security certificates or any notes represented by these certificates for any purpose under the instruments governing the rights and obligations of holders of such notes.

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 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

S-46<br>

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.

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.

S-47<br>

------

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.

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 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 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, U.S. holders 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 or arrangement 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.

**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 OWNERSHIP AND DISPOSITION OF THE NOTES. PROSPECTIVE HOLDERS SHOULD CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM OF THE 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.** 

The terms of the notes provide for payments by us in excess of stated interest or principal, or prior to their scheduled payment dates, under certain circumstances. The possibility of such payments may implicate special rules under U.S. Treasury regulations governing "contingent payment debt instruments." According to those U.S. Treasury regulations, the possibility that such payments of excess or accelerated amounts will be made will not affect the amount of income a holder recognizes in advance of the payment of such excess or accelerated amounts if there is only a remote

S-49<br>

------

#### **TABLE OF CONTENTS**
chance as of the date the notes are issued that such payments will be made. We intend to take the position that the likelihood that such payments will be made is remote within the meaning of the applicable U.S. Treasury regulations. Our position that these contingencies are remote is binding on a holder unless such holder discloses its contrary position to the IRS in the manner required by applicable U.S. Treasury regulations. Our position is not, however, binding on the IRS, and if the IRS were to challenge this position successfully, a holder might be required to, among other things, accrue interest income based on a projected payment schedule and comparable yield, which may be in excess of stated interest, and treat as ordinary income rather than capital gain any income realized on the taxable disposition of a note. In the event a contingency described above occurs, it could affect the amount, timing and character of the income or loss recognized by a holder. Prospective holders should consult their own tax advisors regarding the tax consequences if the notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes will not be considered contingent payment debt instruments.

#### 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:

&nbsp;&nbsp;&nbsp;&nbsp;• an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;• a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia (and certain non-U.S. entities taxed as U.S. corporations under specialized sections of the Code);

&nbsp;&nbsp;&nbsp;&nbsp;• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;• a trust, if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person 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 non-corporate 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, non-corporate U.S. holders. Under the Code and applicable U.S. Treasury regulations, a U.S. holder may be subject to backup withholding with respect to any payments on the notes, or the proceeds of a sale, exchange, redemption, retirement or other taxable 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.* 

#### 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.

S-50<br>

#### **TABLE OF CONTENTS**
*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:* 

&nbsp;&nbsp;&nbsp;&nbsp;• does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

&nbsp;&nbsp;&nbsp;&nbsp;• is not a controlled foreign corporation that is related directly or constructively to us through stock ownership;

&nbsp;&nbsp;&nbsp;&nbsp;• is not a bank that acquired the notes in consideration for an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business; and

&nbsp;&nbsp;&nbsp;&nbsp;• either (a) provides its name and address, and certifies, under penalties of perjury, that it is not a U.S. person as defined under the Code, which certification may be made on an IRS Form W-8BEN, W-8BEN-E or other appropriate form (and any applicable attachments), or (b) holds its notes through various foreign intermediaries and satisfies the certification requirements of applicable U.S. Treasury regulations.

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 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.* 

S-51<br>

------

Information reporting and backup withholding generally are not required with respect to the amount of any proceeds from the sale, exchange, redemption, retirement or other taxable 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.

#### 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") or other retirement plan, account or arrangement 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 IRAs, 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 Huntington, the underwriters, the trustee or any of their respective affiliates (collectively, the "Transaction Parties") 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 and 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 professional 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 with a party in interest and/or a disqualified person (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of any Plan involved in the transaction) solely by reason of providing services to the Plan or by relationship to a service provider, provided that the Plan pays no more, and receives no less, than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied or that any of these 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 or holder 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 Huntington nor any of its 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.

#### **TABLE OF CONTENTS**
The foregoing discussion is general in nature and is not intended to be all inclusive. 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. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in nonexempt prohibited transactions, it is important that fiduciaries or other persons considering purchasing the notes on behalf of or with "plan assets" of any Plan or of any plan subject to Similar Law consult with their counsel regarding the availability of exemptive relief under any of the PTCEs listed above or any other applicable exemption, or the potential consequences of any purchase or holding under Similar Laws, as applicable.

Each purchaser or holder of the notes has exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the notes does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any applicable Similar Laws. The sale of any notes to any plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan.

This summary is based upon the Code, ERISA and the regulations, and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis, and any such change or interpretation could affect the accuracy of the statements in this summary.

#### UNDERWRITING (CONFLICTS OF INTEREST)
Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC and Huntington Securities, Inc. are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an 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.

---

| | | |
|:---|:---|:---|
| **Underwriters** | **Principal Amount** <br>**of Senior Notes** | **Principal Amount** <br>**of Subordinated** <br>**Notes**  |
| Citigroup Global Markets Inc. | &nbsp;&nbsp;$175000000 | $131250000  |

| &nbsp;&nbsp;&nbsp;Total | $1000000000 | $750000000 |

---

The underwriting agreement provides that the obligations of the underwriters 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 non-defaulting 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, 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.

The underwriters expect to deliver the notes in book-entry form only through the facilities of The Depository Trust Company for the accounts of its participants, including Clearstream Banking, S.A. and Euroclear Bank S.A./N.V., as operator of the Euroclear System, against payment in New York, New York on or about January 28, 2026, which is the third Business Day following the date of the pricing of the notes (such settlement cycle being referred to as "T+3"). Under Rule 15c6-1 promulgated under the Exchange Act, trades in the secondary market generally are required to settle in one Business Day unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any date prior to one Business Day before the settlement date will be required, by virtue of the fact that the notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement. Such purchasers should consult their own advisors.

#### Underwriting Discount
The representatives have advised us that the underwriters propose initially to offer the senior 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 0.200% of the principal amount of the senior notes. In addition, the underwriters may allow, and those selected dealers may re-allow, a concession of up to 0.150% of the principal amount of the senior notes, to certain other dealers. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The representatives have advised us that the underwriters propose initially to offer the subordinated 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 0.250% of the principal amount of the subordinated notes. In addition, the underwriters may allow, and those selected dealers may re-allow, a concession of up to 0.200% of the principal amount of the subordinated notes, to certain other dealers. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

S-55<br>

------

#### **TABLE OF CONTENTS**
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 discounts, will be approximately $4.8 million.

#### New Issue of Notes
Each series of notes is 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 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

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 during the stabilization period at a level higher than that which might otherwise prevail. However, stabilization may not necessarily occur. 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. Any stabilization action or over allotment must be conducted by the relevant stabilizing manager(s) (or persons acting on their behalf) in accordance with all applicable laws and rules and will be undertaken at the offices of the relevant stabilizing manager(s) (or persons acting on their behalf).

#### Conflicts of Interest
Our affiliate, Huntington Securities, Inc., 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 Huntington Securities, Inc., 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

S-56<br>

#### **TABLE OF CONTENTS**
management, investment research, principal investment, hedging, financing and brokerage activities. 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.

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. Any such credit default swaps or short positions could adversely affect future trading prices of 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 to clients that they acquire, long and/or short positions in such securities and instruments.

#### Selling Restrictions

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.

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 (EU) 2016/97 (as amended), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the "Prospectus Regulation"); and an offer includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes. 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.

This prospectus supplement has been prepared on the basis that any offer of notes in the UK will be made pursuant to an exemption under the UK Prospectus Regulation and the FSMA from the requirement to publish a prospectus for offers of notes.

#### ABOUT THIS PROSPECTUS
This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission (the "SEC") using a "shelf" registration or continuous offering process. Under this shelf process, we, or, under certain circumstances, 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:

&nbsp;&nbsp;&nbsp;&nbsp;• common stock;

&nbsp;&nbsp;&nbsp;&nbsp;• preferred stock;

&nbsp;&nbsp;&nbsp;&nbsp;• depositary shares;

&nbsp;&nbsp;&nbsp;&nbsp;• senior debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• junior subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• warrants;

&nbsp;&nbsp;&nbsp;&nbsp;• stock purchase contracts for securities;

&nbsp;&nbsp;&nbsp;&nbsp;• guarantees; or

&nbsp;&nbsp;&nbsp;&nbsp;• units.

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 offers 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."

The registration statement containing this prospectus, including exhibits to the registration statement, provides additional information about us and the securities offered under this prospectus. The registration statement can be read at the SEC website or at the SEC offices mentioned under the heading "Where You Can Find More Information."

We have not, and the underwriters and their affiliates and agents have not, authorized any person to provide any information or represent anything about us other than what is contained or incorporated by reference in this prospectus or the applicable prospectus supplement prepared by or on behalf of us or to which we have referred you. 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. The Issuer may only use this prospectus to sell securities if it is accompanied by a prospectus supplement which includes the specific terms of that offering. The Issuer is only offering these securities in jurisdictions where the offer is permitted. 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.

#### **TABLE OF CONTENTS**
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 Huntington Securities, Inc., 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.

#### **TABLE OF CONTENTS**

#### FORWARD-LOOKING STATEMENTS
This prospectus, the accompanying prospectus supplement 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, Section 21E of the Securities Exchange Act, and the Private Securities Litigation Reform Act of 1995.

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; deterioration in business and economic conditions, including persistent inflation, supply chain issues or labor shortages, instability in global economic conditions and geopolitical matters, as well as volatility in financial markets; changes in U.S. trade policies, including the imposition of tariffs and retaliatory tariffs; the impact of pandemics and other catastrophic events or disasters on the global economy and financial market conditions and our business, results of operations, and financial condition; the impacts related to or resulting from bank failures and other volatility, including potential increased regulatory requirements and costs, such as FDIC special assessments, long-term debt requirements and heightened capital requirements, and potential impacts to macroeconomic conditions, which could affect the ability of depository institutions, including us, to attract and retain depositors and to borrow or raise capital; unexpected outflows of uninsured deposits which may require us to sell investment securities at a loss; changing interest rates which could negatively impact the value of our portfolio of investment securities; the loss of value of our investment portfolio which could negatively impact market perceptions of us and could lead to deposit withdrawals; the effects of social media on market perceptions of us and banks generally; cybersecurity risks; 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 including those implementing our "Fair Play" banking philosophy; changes in policies and standards for regulatory review of bank mergers; 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, 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 Annual Report on Form 10-K for the year ended December 31, 2024, under the captions "Forward-Looking Statements" and "Risk Factors," and the documents subsequently filed by us with the SEC.

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.
