RISK FACTORS

An investment in our securities is subject to risks inherent to our business. Before making an investment decision, you should carefully consider the risks and uncertainties described below together with the risk factors and other information included in our Annual Report on Form 10-K for the year ended December 31, 2025 and in other documents that we subsequently file with the SEC, all of which are incorporated by reference into this prospectus supplement and the accompanying prospectus. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also impair our business operations. See also the discussion under the heading "Cautionary Note Concerning Forward-Looking Statements." This prospectus supplement and the accompanying prospectus are qualified in their entirety by these risk factors. If any of these risks actually occurs, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.

Risk Factors Related to the Notes

The Notes will be unsecured and subordinated to any existing and future senior indebtedness.

The Notes will be subordinated obligations of FMC (at the holding company level). Accordingly, they will be junior in right of payment and in certain events of insolvency to our existing and all future senior indebtedness as described under "Description of the Notes." Our senior indebtedness includes all indebtedness, except indebtedness that is expressly subordinated to or ranked pari passu with the Notes, subject to certain exceptions. The Notes will rank equally in right of payment and in certain events of insolvency to all other unsecured subordinated indebtedness of FMC the terms of which provide that such indebtedness ranks equally with the Notes, including debt securities issued in the future under the Indenture. The Notes will rank senior in right of payment and upon our liquidation to (i) our existing junior subordinated debentures underlying outstanding trust preferred securities and (ii) any of our future indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to indebtedness such as the Notes. In addition, the Notes will be structurally subordinated to all existing and future indebtedness, liabilities, and other obligations, including without limitation the Bank's depositors, liabilities to general creditors, and liabilities arising in the ordinary course of business or otherwise.

In addition, the Notes will not be secured by any of our assets. As a result, the Notes will be effectively subordinated to all of our secured indebtedness to the extent of the value of the assets securing such indebtedness. The Indenture governing the Notes does not limit the amount of senior indebtedness and other financial obligations or secured obligations that we or our subsidiaries may incur.

As of June 30, 2026, on a consolidated basis, our outstanding deposits and other liabilities totaled approximately $18.7 billion, which includes approximately $18.6 billion of liabilities that rank structurally senior to the Notes. In addition, as of June 30, 2026, we (at the holding company level) had $13 million in indebtedness that would rank senior to the Notes, $29 million aggregate principal amount of indebtedness that would rank pari passu to the Notes, and $52 million aggregate principal amount of indebtedness related to existing junior subordinated debentures underlying outstanding trust preferred securities that would rank junior to the Notes.

As a result of the subordination provisions described above, holders of the Notes may not be fully repaid in the event of our bankruptcy, liquidation, or reorganization.

The Notes are subordinated obligations whose subordination and priority provisions may not operate as expected, which could materially reduce recoveries for holders.

Although the Notes include contractual subordination provisions, the effectiveness of those provisions (and the practical ordering of payments among different categories of claimants) is subject to applicable insolvency,

S-10

receivership and other laws, and the exercise of discretion by a bankruptcy court, a receiver (including the FDIC, as receiver) or other governmental authority in a resolution or administrative proceeding. In particular:

For example, we have existing junior subordinated debentures underlying our outstanding trust preferred securities (the "junior subordinated debentures"). The junior subordinated debentures are described in the applicable governing documents as ranking contractually pari passu with our trade payables. At the same time, the Notes rank senior to the junior subordinated debentures but junior to our trade payables. The practical effect of this ranking, including in relation to the Notes' own subordination to trade payables and priority over the junior subordinated debentures may be subject to differing interpretations in an insolvency, receivership, or similar proceeding.

If any challenge to the subordination framework were successful, if priorities were applied differently than described in the governing documents, or if the ordering of claims were otherwise uncertain, holders of the Notes could experience reduced or delayed payments, increased volatility in the trading price of the Notes and greater uncertainty regarding ultimate recoveries. In particular, the manner in which amounts payable to holders of the Notes are calculated and applied relative to our obligations to trade payables could affect the amount of Note proceeds that holders of the Notes are ultimately entitled to retain.

The Notes will not be insured or guaranteed by the FDIC, any other governmental agency, or any of our subsidiaries. The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries generally will be paid from those subsidiaries' assets before holders of the Notes would have any claims to those assets.

The Notes are not savings accounts, deposits, or other obligations of the Bank or any of our non-bank subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or public or private insurer. The Notes are obligations of FMC (at the holding company level) only and are neither obligations of, nor guaranteed by, any of our subsidiaries. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries (including, in the case of the Bank, its depositors) generally will be paid from those subsidiaries' assets before holders of the Notes would have any claims to those assets. Even if we become a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any debt of that subsidiary senior to that held by us, and our rights could otherwise be subordinated to the rights of other creditors and depositors of that subsidiary. Furthermore, none of our subsidiaries is under any obligation to make payments to us, and any payments to us depend on the earnings or financial condition of our subsidiaries and various business considerations. Statutory, contractual, or other restrictions also limit our subsidiaries' ability to pay dividends or make distributions, loans, or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to make interest and principal payments on the Notes.

S-11

The Indenture governing the Notes does not contain any limitations on our ability to incur additional indebtedness, grant or incur a lien on our assets, sell or otherwise dispose of assets, pay dividends, pay, redeem or prepay indebtedness that is junior in payment priority to the Notes, or repurchase shares of our capital stock.

Neither we nor any of our subsidiaries are restricted from incurring additional indebtedness or other liabilities, including additional senior or subordinated indebtedness, under the Indenture governing the terms of the Notes. If we incur additional indebtedness or liabilities, our ability to pay our obligations on the Notes could be adversely affected. We expect that we will from time to time incur additional indebtedness and other liabilities. In addition, we are not restricted under the Indenture governing the Notes from granting or incurring a lien on any of our assets, selling or otherwise disposing of any of our assets, paying dividends, paying, redeeming or prepaying indebtedness junior to the Notes, or issuing or repurchasing our securities, including our regular quarterly dividends and share repurchases pursuant to our previously announced share repurchase program.

We may also, from time to time, without notice to or the consent of the holders of the Notes, issue additional notes ranking equally with the Notes, which may be consolidated and form a single series with the Notes, as well as other indebtedness ranking senior to the Notes. Any such future issuances would increase the aggregate amount of claims ranking equally with, or senior to, the Notes and could adversely affect the amount that holders of the Notes would recover in the event of our bankruptcy, liquidation, receivership, or reorganization.

In addition, there are no financial covenants in the Indenture governing the Notes. Except as expressly provided in the Indenture, you are not protected under the Indenture governing the Notes in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger, or similar transaction that may adversely affect you.

Payments on the Notes will depend on receipt of dividends and distributions from our subsidiaries.

We are a bank holding company and we conduct substantially all of our operations through subsidiaries, including the Bank. We depend on dividends, distributions, and other payments from our subsidiaries to meet our obligations, including to fund payments on the Notes.

Federal and state banking regulations limit dividends from our bank subsidiary to us. Generally, banks are prohibited from paying dividends when doing so would cause them to fall below regulatory minimum capital levels. Under Indiana state law, a bank may pay cash dividends only out of adjusted retained net profits for the year in which the dividend is paid and the two preceding years.

In addition, federal bank regulatory agencies have the authority to prohibit the Bank from engaging in unsafe or unsound practices in conducting its business. The payment of dividends or other transfers of funds to us, depending on the financial condition of the Bank, could be deemed an unsafe or unsound practice.

Accordingly, we can provide no assurance that we will receive dividends or other distributions from our bank subsidiary and our other subsidiaries in an amount sufficient to pay interest on or principal of the Notes.

Our indebtedness could adversely affect our financial results and prevent us from fulfilling our obligations under the Notes.

In addition to our currently outstanding indebtedness and any additional indebtedness we may incur pursuant to this offering, we may be able to borrow substantial additional indebtedness, including senior indebtedness, in the future. If new indebtedness is incurred in addition to our current debt levels, the related risks that we now face could increase.

S-12

Our indebtedness, including the indebtedness we may incur in the future, could have important consequences for the holders of the Notes, including:

The Indenture does not limit the incurrence of additional indebtedness by us, including secured indebtedness, which would be effectively senior to the Notes to the extent of the value of the collateral securing such indebtedness.

We may not be able to generate sufficient cash to service all of our indebtedness, including the Notes.

Our ability to make scheduled payments of principal and interest, or to satisfy our obligations in respect of our indebtedness or to refinance our indebtedness, will depend on the future performance of our operating subsidiaries. Prevailing economic conditions (including interest rates), regulatory constraints, including, without limitation, limiting distributions to us from the Bank and required capital levels with respect to the Bank, and financial, business, and other factors, many of which are beyond our control, will also affect our ability to meet these needs. Our subsidiaries may not be able to generate sufficient cash flows from operations, or we may be unable to obtain future borrowings in an amount sufficient to enable us to pay our indebtedness, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness at or before maturity. We may not be able to refinance any of our indebtedness when needed (including, without limitation, upon commencement of the floating rate period) on commercially reasonable terms or at all.

Regulatory guidelines may restrict our ability to pay the principal of, and accrued and unpaid interest on, the Notes.

As a bank holding company, our ability to pay the principal of, and interest on, the Notes is subject to the rules and guidelines of the Federal Reserve regarding capital adequacy. We intend to treat the Notes as "Tier 2 capital" under these rules and guidelines. The Federal Reserve guidelines generally require us to review the effects of the cash payment on Tier 2 capital instruments, such as the Notes, on our overall financial condition. The guidelines also require that we review our net income for the current and past four quarters, and the amounts we have paid on Tier 2 capital instruments for those periods, as well as our projected rate of earnings retention. Moreover, pursuant to federal law and Federal Reserve regulations, as a bank holding company, we are required to act as a source of financial and managerial strength to the Bank and commit resources to its support, including, without limitation, the guarantee of its capital plans if it is undercapitalized. Such support may be required at times when we may not otherwise be inclined or able to provide it. As a result of the foregoing, we may be unable to pay accrued interest on the Notes on one or more of the scheduled interest payment dates, or at any other time, or the principal of the Notes at the maturity of the Notes.

In addition, the capital adequacy rules and guidelines described above have been, and may continue to be, the subject of proposed reforms by the Federal Reserve and other banking regulators. Any future amendment, supplement, or replacement of these rules could change the criteria for Tier 2 capital qualification generally, independent of the discrete Tax Event or Tier 2 Capital Event redemption triggers described below, and could adversely affect our capital planning and the value of, and market for, the Notes.

S-13

If we were to be the subject of a bankruptcy proceeding under Chapter 11 of the U.S. Bankruptcy Code, then the bankruptcy trustee would be deemed to have assumed, and would be required to cure immediately, any deficit under any commitment we have to any of the federal banking agencies to maintain the capital of the Bank, and any other insured depository institution for which we have such a responsibility, and any claim for breach of such obligation would generally have priority over most other unsecured claims.

Holders of the Notes will have limited rights, including limited rights of acceleration, if there is an event of default.

Payment of principal on the Notes may be accelerated only in the case of certain events of bankruptcy or insolvency involving us or the Bank. There is no automatic acceleration, or right of acceleration, in the case of default in the payment of principal of or interest on the Notes, or in the performance of any of our other obligations under the Notes or the Indenture governing the Notes. Our regulators can, if we or the Bank become subject to an enforcement action, prohibit the Bank from paying dividends to us, and prevent our payment of interest on or principal of the Notes and any dividends on our capital stock, but such limits will not permit acceleration of the Notes. In addition, the terms of the Notes do not require us to offer to repurchase the Notes upon the occurrence of a change of control, merger, recapitalization, or similar transaction involving us or our subsidiaries. The Notes are not subject to repayment at the option of the holders under any circumstances prior to maturity. As a result, holders of the Notes would have no right to require early repayment if we were to undergo a transaction that adversely affects our creditworthiness, and would continue to bear the credit and market risk of holding the Notes to maturity or until we elect to redeem them. See "Description of the Notes - Events of Default; Limitation on Suits."

An active trading market for the Notes may not develop.

The Notes constitute a new issue of securities for which there is no existing trading market. We do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes in any automated dealer quotation system. We cannot provide you with any assurance regarding whether a trading market for the Notes will develop, the ability of holders of the Notes to sell their Notes or the prices at which holders may be able to sell their Notes. The underwriters have advised us that they currently intend to make a secondary market in the Notes. The underwriters, however, are not obligated to do so, and any market-making with respect to the Notes may be discontinued at any time without notice. There may be a limited number of buyers if you decide to sell your Notes. This may affect the price you receive for your Notes or your ability to sell your Notes at all. Investors in the Notes may not be able to sell the Notes at all or may not be able to sell the Notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

If a trading market for the Notes develops, changes in the debt markets, among others, could adversely affect your ability to liquidate your investment in the Notes and the market price of the Notes.

Many factors could affect the trading market for, and the trading value of, the Notes. These factors include: the method of calculating the principal, premium, if any, interest, or other amounts payable, if any, on the Notes; the time remaining to the maturity of the Notes; the ranking of the Notes; the redemption features of the Notes; the outstanding amount of subordinated notes with terms similar or identical to the Notes offered hereby; the prevailing interest rates being paid by other companies similar to us; changes in U.S. interest rates; whether the ratings on the Notes or us provided by any rating agency have changed; our financial condition, financial performance, and future prospects; the level, direction, and volatility of market interest rates generally; general economic conditions of the capital markets in the United States; and geopolitical conditions and other financial, political, regulatory, and judicial events that affect the capital markets generally. The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could adversely affect the trading market (if any) for, and the market price of, the Notes.

S-14

Because the Notes may be redeemed at our option under certain circumstances prior to their maturity, if we elect to redeem all or any portion of the Notes, you may be subject to reinvestment risk.

On or after    ,    , we may, at our option, redeem the Notes, in whole or in part. In addition, we may redeem the Notes prior to maturity, including prior to    , _, at our option, in whole but not in part, upon or after the occurrence of (1) a Tax Event (as defined below in "Description of the Notes - Redemption"); (2) a subsequent event, as a result of which there is more than an insubstantial risk that we would not be entitled to treat the Notes as Tier 2 capital for regulatory capital purposes; or (3) a requirement that we register as an investment company under the Investment Company Act of 1940. The redemption price for any redemption is 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of redemption. Any redemption of the Notes will be subject to the receipt of the approval of the Federal Reserve, to the extent then required under applicable laws or regulations, including capital regulations. Any such redemption may have the effect of reducing the income or return that you may receive on an investment in the Notes by reducing the term of the investment. Under current regulatory capital guidelines, the aggregate principal amount of the Notes that will count as Tier 2 capital will be reduced by 20% in each of the last five years prior to the Maturity Date of the Notes. As a result, we may be more likely to redeem the Notes prior to their Maturity Date. If this occurs, you may not be able to reinvest the proceeds at an interest rate comparable to the rate paid on the Notes. See "Description of the Notes - Redemption."

We may elect to redeem the Notes on or after the date on which they become redeemable at our option; however, investors should not expect us to make such election on such date when the Notes are first redeemable or at any time thereafter. Under Federal Reserve regulations, unless the Federal Reserve authorizes us in writing to do otherwise, we may not redeem the Notes unless they are replaced with other Tier 2 capital instruments or unless we can demonstrate to the satisfaction of the Federal Reserve that, following redemption, we will continue to hold capital commensurate with our risk.

The amount of interest payable on the Notes will vary after    ,     .

During the fixed rate period, the Notes will bear interest at an initial rate of    % per annum. Thereafter, the Notes will bear interest at a floating rate per annum equal to the Benchmark rate (which is expected to be Three-Month Term SOFR) plus    basis points, subject to the provisions under "Description of the Notes - General." The per annum interest rate that is determined at the reference time for each interest period will apply to the entire quarterly interest period following such determination date even if the Benchmark rate increases during that period.

Floating rate notes bear additional significant risks not associated with fixed rate debt securities. These risks include fluctuation of the interest rates and the possibility that you will receive an amount of interest that is lower than expected. We have no control over a number of matters, including, without limitation, economic, financial, and political events, that are important in determining the existence, magnitude, and longevity of market volatility and other risks and their impact on the value of, or payments made on, the Notes. In recent years, interest rates have been volatile, and that volatility may be expected in the future.

Our published credit ratings may not reflect all risks of an investment in the Notes.

The published credit ratings of us or our indebtedness are an assessment by rating agencies of our ability to pay our debts when due. These ratings are not recommendations to purchase, hold, or sell the Notes, inasmuch as the ratings do not comment as to market price or suitability for a particular investor, are limited in scope, and do not address all material risks relating to an investment in the Notes, but rather reflect only the view of each rating agency at the time the rating is issued. The published credit ratings assigned to the Notes may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or trading value of, the Notes.

Accordingly, you should consult your own financial and legal advisors as to the risks entailed by an investment in the Notes and the suitability of investing in the Notes in light of your particular circumstances.

S-15

A downgrade of our credit ratings or the ratings of our subsidiaries or other financial institutions could have a material adverse impact on us and the value of and market for the Notes.

Rating agencies continuously evaluate us and our subsidiaries, and their ratings of our long-term and short-term debt are based on a number of factors, including financial strength, as well as factors not entirely within our control, such as conditions affecting the financial services industry generally. In light of these reviews and the continued focus on the financial services industry generally, we and our subsidiaries may not be able to maintain our current credit ratings. Ratings downgrades by a rating agency could have a significant and immediate impact on our funding and liquidity through cash obligations, reduced funding capacity, and collateral triggers. A reduction in our or our subsidiaries' credit ratings could also increase our borrowing costs and limit access to the capital markets. These changes could have a material adverse impact on the value of and market for the Notes.

Downgrades in the credit or financial strength ratings assigned to the counterparties with whom we transact could create the perception that our financial condition will be adversely impacted as a result of potential future defaults by such counterparties. Additionally, we could be adversely affected by a general, negative perception of financial institutions caused by the downgrade of other financial institutions. Accordingly, ratings downgrades for other financial institutions could affect the market price of our stock and could limit our access to or increase our cost of capital. These changes could have a material adverse impact on the value of and market for the Notes.

Investors should not rely on indicative or historical data concerning SOFR or Three-Month Term SOFR.

The interest rate during the floating rate period will be determined using Three-Month Term SOFR (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to Three-Month Term SOFR, in which case the rate of interest will be based on the next-available Benchmark Replacement, which is Compounded SOFR (as described under "Description of the Notes")).

FRBNY began to publish SOFR in April 2018 and the SOFR Index in March 2020 and has published modeled pre-publication estimates of SOFR going back to 2014. Such pre-publication estimates inherently involve assumptions, estimates, and approximations. Hypothetical or historical performance data and trends are not indicative of, and have no bearing on, the potential performance of SOFR and therefore you should not rely on any such data or trends as an indicator of future performance.

Term SOFR and SOFR may be more volatile than other benchmark or market rates.

Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and Term SOFR and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the Notes may fluctuate more than floating rate securities that are linked to less volatile rates.

Changes in Term SOFR and SOFR could adversely affect holders of the Notes and the trading prices for the Notes.

Because Term SOFR and SOFR are based on data received from other sources, we have no control over its determination, calculation, or publication. There is no assurance that either SOFR or Term SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which Term SOFR or SOFR are calculated is changed, that change may result in a reduction in the amount of interest that accrues on the Notes during the floating rate period, which may adversely affect the trading prices of the Notes. Further, if the Benchmark rate on the Notes during the floating rate period on any determination date declines to zero or becomes negative, the Benchmark will be deemed to equal zero. In addition, once the Benchmark rate for the Notes for each interest period during the floating rate period is determined by the calculation agent on the determination date, interest on the Notes will accrue based on such Benchmark rate for the applicable interest period and will not be subject to change during such interest period. There is no assurance that changes in Term SOFR or SOFR could not have a material adverse effect on the yield on, value of, and market for the Notes.

S-16

The interest rate for the Notes during the applicable floating rate period may be determined based on a rate other than Three-Month Term SOFR.

Under the terms of the Notes, the interest rate on the Notes for each interest period during the applicable floating rate period will be based on Three-Month Term SOFR, a forward-looking term rate for a tenor of three months that will be based on SOFR. Uncertainty surrounding the adoption and use of forward-looking term rates based on SOFR could have a material adverse effect on the return on, value of, and market for the Notes. Use and adoption of Three-Month SOFR or forward-looking term rates based on SOFR may require updates to systems and operational processes to facilitate the calculation and determination thereof. If, at the commencement of the floating rate period for the Notes, we determine that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the interest rate on the Notes during the applicable floating rate period (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to that next-available Benchmark Replacement).

Under the terms of the Notes, the calculation agent (which may be us) is expressly authorized to make determinations, decisions, or elections with respect to technical, administrative, or operational matters that it decides are appropriate to reflect the use of Three-Month Term SOFR as the interest rate basis for the Notes, which are defined in the terms of the Notes as "Three-Month Term SOFR Conventions." Such determination and implementation of any Three-Month Term SOFR Conventions could result in adverse consequences to the amount of interest that accrues on the Notes during the applicable floating rate period, which could adversely affect the return on, value of, and market for the Notes.

Any Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR.

Under the benchmark transition provisions of the Notes, if the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, then the floating interest rate on the Notes for each interest period during the floating rate period will be determined using the next-available Benchmark Replacement (which may include a related Benchmark Replacement Adjustment). However, the Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR. For example, Compounded SOFR, the first-available Benchmark Replacement, is the compounded average of the daily SOFR calculated in arrears, while Three-Month Term SOFR is intended to be a forward-looking rate with a tenor of three months. In addition, very limited market precedent exists for securities that use Compounded SOFR as the rate basis, and the method for calculating Compounded SOFR in those precedents varies. Further, the ISDA Fallback Rate (as defined under "Description of the Notes"), which is another Benchmark Replacement, has not yet been established and may change over time.

The implementation of Benchmark Replacement Conforming Changes could adversely affect holders of the Notes.

Under the benchmark transition provisions of the Notes, if Three-Month Term SOFR has been discontinued or if a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected or formulated by: (i) the Relevant Governmental Body (such as the ARRC or FRBNY); (ii) the International Swaps and Derivatives Association, Inc. ("ISDA"); or (iii) in certain circumstances, the calculation agent, which may be us. In addition, the benchmark transition provisions expressly authorize the calculation agent (which may be us) to make certain changes, which are defined in the terms of the Notes as "Benchmark Replacement Conforming Changes," with respect to, among other things, the determination of interest periods, and the timing and frequency of determining rates and making payments of interest. 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

S-17

amount of interest that accrues on the Notes during any interest period during the floating rate period, which could adversely affect the yield on, value of, and market for the Notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark rate that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark rate that it is replacing.

We or an affiliate of ours will or could have authority to make determinations and elections that could affect the return on, value of and market for the Notes.

Under the terms of the Notes, we may make certain determinations, decisions, and elections with respect to the Benchmark rate on the Notes during the floating rate period, including, without limitation, any determination, decision, or election required to be made by the calculation agent that the calculation agent fails to make. We will make any such determination, decision, or election in our sole discretion, and any such determination, decision, or election that we make could affect the amount of interest that accrues on the Notes during any interest period in the floating rate period. If the calculation agent fails, when required, to make a determination that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, or fails, when required, to determine the Benchmark Replacement and Benchmark Replacement Adjustment, then we will make those determinations in our sole discretion. Furthermore, we or an affiliate of ours may serve as calculation agent. We expect to act as the initial calculation agent and, though we will appoint a calculation agent prior to the commencement of the floating rate period, we may appoint ourselves or an affiliate and we cannot assure you that we will appoint an independent third-party calculation agent at any time. Any exercise of discretion by us under the terms of the Notes, including, without limitation, any discretion exercised by us or by an affiliate acting as calculation agent, could present a conflict of interest. In making the required determinations, decisions, and elections, we or an affiliate of ours acting as calculation agent may have economic interests that are adverse to the interest of the holders of the Notes, and those determinations, decisions, or elections could have a material adverse effect on the yield on, value of, and market for the Notes. All determinations, decisions, or elections by us, or by us or an affiliate acting as calculation agent, under the terms of the Notes will be conclusive and binding absent manifest error.

The use of the net proceeds from the sale of the Notes will be at the discretion of our management and could change depending on unforeseen events or changes in current business conditions or circumstances.

Our management will have broad discretion in the use of the net proceeds from the sale of the Notes. The descriptions in this prospectus supplement of our use of the proceeds from the sale of the Notes represent our intentions based upon our present plans and business conditions. The occurrence of unforeseen events or changed business conditions, however, could result in the application of the net proceeds of the offering in a manner other than as described in this prospectus supplement. The precise amounts and timing of our use of the net proceeds will depend on our, and our subsidiaries', funding requirements and the availability of other funds.

S-18

USE OF PROCEEDS

DESCRIPTION OF THE NOTES

We will issue the Notes under the Base Indenture, as supplemented by the Supplemental Indenture. You may request a copy of the Indenture from us as described under "Incorporation of Certain Documents by Reference." We have summarized the material terms of the Indenture and the Notes below, but the summary does not purport to be complete and is subject to and qualified in its entirety by reference to the Indenture and the Notes. The following description of the terms of the Indenture and the Notes supplements and, to the extent inconsistent therewith, replaces and supersedes the description of the general terms and provisions of the subordinated debt securities in the accompanying prospectus.

You should read the Indenture and the Notes because they, and not this description, define your rights as holders of the Notes. For purposes of this section, references to "FMC," the "Corporation," "we," "us," and "our" include only FMC and not any of its subsidiaries.

General

The Notes will be unsecured, subordinated obligations of the Corporation and will mature on   ,      unless redeemed prior to such date in accordance with the provisions set forth below under "-Redemption." The Notes will be issued and may be transferred only in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Unless previously redeemed prior to maturity, we will repay the Notes at 100% of their principal amount, together with accrued and unpaid interest thereon to, but excluding, the Maturity Date, at their maturity. We will pay principal of and interest on the Notes in U.S. dollars.

The Notes will constitute our unsecured debt obligations and will rank equally among themselves, will rank senior to our existing junior subordinated debentures and any of our future indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to note indebtedness such as the Notes, and will rank junior in right of payment to any of our future senior indebtedness as described below under "-Subordination of the Notes." In addition, the Notes will be structurally subordinated to all existing and future liabilities of our subsidiaries and will be effectively subordinated to our existing and future secured indebtedness, to the extent of the value of the collateral securing such indebtedness. See "-Subordination of the Notes." No sinking fund will exist for the Notes, and no sinking fund payments will be made with respect to the Notes. The Notes will not be convertible into or exchangeable for any other securities or property. Except as described below under "-Form, Denomination, Transfer, Exchange, and Book-Entry Procedures," the Notes will be issued only in book-entry form and will be represented by one or more global notes registered in the name of Cede & Co., as the nominee of DTC. See "-Form, Denomination, Transfer, Exchange, and Book-Entry Procedures."

The Notes offered hereby will be issued under the Indenture. We may, from time to time, without notice to, or the consent of, the holders of the Notes, issue additional Notes ranking equally with the Notes and identical to the Notes previously issued in all respects (except for the issue date, the offering price, the initial interest accrual date, and the first interest payment date) in order that such additional Notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption, or otherwise as the Notes. However, any additional notes of the series of which the Notes are a part that are issued and are not fungible with the outstanding Notes of such series for U.S. federal income tax purposes will be issued under one or more separate CUSIP numbers and ISIN numbers. No limit exists on the aggregate principal amount of the Notes of this series that we may issue in the future.

The Indenture contains no covenants or restrictions restricting the incurrence of indebtedness or other obligations by us or by our subsidiaries, including the Bank. The Indenture contains no financial covenants requiring us to achieve or maintain any minimum financial results relating to our financial position or results of operations or meet or exceed any financial ratios, as a general matter or in order to incur additional indebtedness

S-22

or obligations, or to maintain any reserves. Moreover, neither the Indenture nor the Notes contain any covenants prohibiting us from, or limiting our right to, incur additional indebtedness or obligations, to grant liens on our assets to secure our indebtedness or other obligations that are senior in right of payment to the Notes, to repurchase our stock or other securities, including any of the Notes, or to pay dividends or make other distributions to our stockholders. In addition, neither the Indenture nor the Notes contain any provision that would provide protection to the holders of the Notes against a sudden and dramatic decline in our credit quality, including resulting from a merger, takeover, recapitalization, or similar restructuring or other events involving us or our subsidiaries that may adversely affect our credit quality.

The Notes are not deposits in the Bank and are not insured or guaranteed by the FDIC or any other government agency or instrumentality. The Notes are solely obligations of the Corporation and are neither obligations of, nor guaranteed by, the Bank or any of our other subsidiaries or affiliates.

No recourse will be available for the payment of principal of or interest on any Note, for any claim based thereon, or otherwise in respect thereof, against any incorporator, stockholder, employee, agent, officer, or director, as such, past, present, or future, of ours or of any successor entity, it being expressly understood that all such liability is waived and released as a condition of, and as a consideration for, the execution of the Supplemental Indenture and the issuance of the Notes.

Payment of the full principal amount of the Notes will be due on   ,      (the "Maturity Date"), unless the Notes are redeemed prior to the Maturity Date.

Fixed Rate Period

From and including the date of issuance to, but excluding,  ,      (unless redeemed prior to such date as contemplated below under "-Redemption"), which we refer to as the "fixed rate period," the Notes will bear interest at a rate of   % per year. During the fixed rate period, interest on the Notes will accrue from and including   , 2026, and will be payable semiannually in arrears on   and   of each year during the fixed rate period, each a "fixed period interest payment date," commencing on   , 2027. During the fixed rate period, interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward. The interest payable on the Notes on any fixed period interest payment date will, except as noted below, be paid to the person in whose name the Notes are registered at the close of business on the 15th calendar day (whether or not a business day (as defined below)) immediately preceding the fixed period interest payment date. If any fixed period interest payment date for the Notes or the date for the payment of principal for the Notes occurring during the fixed rate period falls on a day that is not a business day, the Corporation will postpone the interest or principal payment to the next succeeding business day, but the payments made on such dates will be treated as being made on the date that the payment was first due and the holders of the Notes will not be entitled to any further interest, principal, or other payments with respect to such postponements.

Floating Rate Period

From and including   ,      to, but excluding, the Maturity Date (unless redeemed prior to such date as contemplated below under "-Redemption"), which we refer to as the "floating rate period," the Notes will bear interest at a floating rate per year equal to the Benchmark (which is expected to be Three-Month Term SOFR), plus basis points. Notwithstanding the foregoing, if the Benchmark is less than zero, the Benchmark will be deemed to be zero.

During the floating rate period, interest on the Notes will accrue from and including  ,      and will be payable quarterly in arrears on   ,   ,    and    of each year (each a "floating period interest payment date" and, together with any fixed period interest payment date, an "Interest Payment Date"), commencing on   ,     , and interest will be computed on the basis of a 360-day year and the actual

S-23

number of days elapsed. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward.

For the purpose of calculating the interest on the Notes for each floating rate interest period during the floating rate period when the Benchmark is Three-Month Term SOFR, "Three-Month Term SOFR" means the rate for Term SOFR for a tenor of three months that is published by the Term SOFR Administrator at the Reference Time for any floating rate interest period, as determined by the calculation agent after giving effect to the Three-Month Term SOFR Conventions. All percentages used in or resulting from any calculation of Three-Month Term SOFR will be rounded, if necessary, to the nearest one-hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. When we use the term "floating rate interest period" we mean the period from and including the immediately preceding floating period interest payment date in respect of which interest has been paid or duly provided for, to, but excluding, the applicable floating period interest payment date or Maturity Date or date of earlier redemption, if applicable (except that the first floating rate interest period will commence on  ,     ). See "Calculation Agent."

The following definitions apply to the foregoing definition of Three-Month Term SOFR:

"Benchmark" means, initially, Three-Month Term SOFR; provided that, if the calculation agent determines on or prior to the Reference Time for any floating rate interest period that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement for such floating rate interest period and any subsequent floating rate interest periods.

"Corresponding Tenor" means (i) with respect to Term SOFR, three months, and (ii) with respect to a Benchmark Replacement, a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

"FRBNY's Website" means the website of the FRBNY at http://www.newyorkfed.org, or any successor source. The foregoing Internet 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 by reference herein or therein.

"Reference Time" with respect to any determination of the Benchmark means (i) if the Benchmark is Three-Month Term SOFR, the date that is two (2) U.S. Government Securities Business Days prior to the start of the relevant Floating Rate Interest Period, or such other time determined by the calculation agent after giving effect to the Three-Month Term SOFR Conventions, and (ii) if the Benchmark is not Three-Month Term SOFR, the time determined by the calculation agent after giving effect to the Benchmark Replacement Conforming Changes.

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

"SOFR" means the secured overnight financing rate published by the FRBNY, as the administrator of SOFR (or any successor administrator), on the FRBNY's Website.

"Term SOFR" means the forward-looking term rate for the applicable Corresponding Tenor based on SOFR as published by the Term SOFR Administrator.

"Term SOFR Administrator" means CME Group Benchmark Administration Limited (CBA) (or a successor administrator of Three-Month Term SOFR selected by the calculation agent in its reasonable discretion).

"Three-Month Term SOFR Conventions" means any determination, decision, or election with respect to any technical, administrative, or operational matter (including with respect to the manner and timing of the

S-24

publication of Three-Month Term SOFR, or changes to the definition of "floating rate interest period," timing and frequency of determining Three-Month Term SOFR with respect to each floating rate interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the calculation agent determines may be appropriate to reflect the use of Three-Month Term SOFR as the Benchmark in a manner substantially consistent with market practice (or, if the calculation agent determines that adoption of any portion of such market practice is not administratively feasible or if the calculation agent determines that no market practice for the use of Three-Month Term SOFR exists, in such other manner as the calculation agent determines is reasonably necessary).

"U.S. Government Securities Business Day" means any day except for (a) a Saturday, (b) a Sunday, or (c) 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 United States government securities.

The terms "Benchmark Replacement Conforming Changes," "Benchmark Replacement Date," "Benchmark Replacement," "Benchmark Replacement Adjustment," and "Benchmark Transition Event" have the meanings set forth under the heading "-Effect of Benchmark Transition Event."

Notwithstanding the foregoing paragraphs related to the determination of interest, if the calculation agent determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date (each as defined below) have occurred with respect to Three-Month Term SOFR, then the provisions set forth under the heading "-Effect of Benchmark Transition Event," which we refer to as the "benchmark transition provisions," will thereafter apply to all determinations of the benchmark used to calculate the interest rate on the Notes for each floating rate interest period. In accordance with the benchmark transition provisions, if the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any floating rate interest period during the floating rate period, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during such floating rate interest period and the remainder of the floating rate period.

Absent manifest error, the calculation agent's determination of the interest rate for a floating rate interest period for the Notes will be binding and conclusive on you, us (if we are not also the calculation agent), and the Trustee. The Trustee will have no duty to confirm or verify any such calculation. By its acquisition of the Notes, each holder of Notes (including, for the avoidance of doubt, each beneficial owner) will acknowledge, accept, consent to, and agree to be bound by our and the calculation agent's determination of the interest rate for each floating rate interest period, including our and its determination of any Benchmark Replacement Conforming Changes, Benchmark Replacement Date, Benchmark Replacement, Benchmark Replacement Adjustment, and Benchmark Transition Event, including as may occur without any prior notice from us or the calculation agent and without the need for us or it to obtain any further consent from any holder. The calculation agent's determination of any interest rate, and its calculation of interest payments, for any floating rate interest period, will be maintained on file at the calculation agent's principal offices and will be made available to any holder of the Notes upon request, and the calculation agent will provide the Corporation and the Trustee with written notice of the interest rate in effect on the Notes promptly after the Reference Time (or such other date of determination for the applicable Benchmark).

If the then-current Benchmark is Three-Month Term SOFR, the calculation agent (which may be us) will have the right to establish the Three-Month Term SOFR Conventions, and if any of the foregoing provisions concerning the calculation of the interest rate and interest payments during the floating rate period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the calculation agent, then the relevant Three-Month Term SOFR Conventions will apply. Furthermore, if the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR at any time when any of the Notes are outstanding, then the foregoing provisions concerning

S-25

the calculation of the interest rate and interest payments during the floating rate period will be modified in accordance with the benchmark transition provisions.

When we use the term "business day," we mean any day, other than a Saturday or Sunday, that is neither a federal holiday nor a day on which banking institutions or trust companies in the City of New York, New York or any place of payment are authorized or obligated by law, regulation, or executive order to close or remain closed; provided that, when used in connection with an amount that bears interest at a rate based on SOFR or Term SOFR or any direct or indirect calculation or determination of SOFR or Term SOFR, the term "business day" means any such day that is also a U.S. Government Securities Business Day.

If any floating period interest payment date or the Maturity Date for the Notes falls on a day that is not a business day, the Corporation will postpone the interest payment or the payment of principal and interest at maturity to the next succeeding business day (and, with respect to the Maturity Date, no additional interest will accrue on the amount payable for the period from and after the Maturity Date), unless, with respect to a floating period interest payment date only, such day falls in the next calendar month, in which case the floating period interest payment date will instead be the immediately preceding day that is a business day, and interest will accrue to, but excluding, such floating period interest payment date as so adjusted.

The interest payable on the Notes on any floating period interest payment date, subject to certain exceptions, will be paid to the person in whose name the Notes are registered at the close of business on the 15th calendar day (whether or not a business day) immediately preceding the floating period interest payment date. Payments will include interest accrued to, but excluding, the relevant floating period interest payment date. However, interest that the Corporation pays on the Maturity Date will be paid to the person to whom the principal will be payable.

Principal and interest on the Notes will be payable by wire transfer in immediately available funds in U.S. dollars at an office or agency of the Corporation maintained for such purpose, which will initially be the corporate trust office of the Trustee.

Subordination of the Notes

Our obligation to make any payment on account of the principal of, or interest on, the Notes will be subordinate and junior in right of payment to the prior payment in full of all of our senior indebtedness.

"Senior indebtedness" means the principal of, and premium, if any, and interest, including interest accruing after the commencement of any bankruptcy proceeding relating to the Corporation, on, or substantially similar payments we make in respect of the following categories of debt, whether that debt is outstanding on the date of execution of the Supplemental Indenture or thereafter incurred, created, or assumed:

S-26

However, "senior indebtedness" excludes:

As used above, the term "purchase-money obligations" means indebtedness, obligations evidenced by a note, debenture, bond, or other instrument, whether or not secured by a lien or other security interest, issued to evidence the obligation to pay or a guarantee of the payment of, and any deferred obligation for the payment of, the purchase price of property but excluding indebtedness or obligations for which recourse is limited to the property purchased, issued, or assumed as all or a part of the consideration for the acquisition of property or services, whether by purchase, merger, consolidation, or otherwise, but does not include any trade accounts payable.

Notwithstanding the foregoing, if the Federal Reserve (or other competent regulatory agency or authority) promulgates any rule or issues any interpretation that defines general creditor(s), the main purpose of which is to establish criteria for determining whether the subordinated debt of a bank holding company is to be included in its capital, then the term "general creditors" as used in the definition of "Senior Indebtedness" will have the meaning as described in that rule or interpretation.

In accordance with the subordination provisions of the Indenture and the Notes, we are permitted to make payments of accrued and unpaid interest on the Notes on the Interest Payment Dates and at maturity and to pay the principal of the Notes at maturity unless:

S-27

In the event of our insolvency, bankruptcy, receivership, liquidation, or other marshalling of our assets and liabilities, we must pay to the holders of all of our senior indebtedness the full amounts of principal of, and premium, if any, and interest on, that senior indebtedness before any payment is made on the Notes. If, after we have paid the senior indebtedness in full, there are any amounts available for payment of the Notes and any of our other indebtedness and obligations ranking equally in right of payment with the Notes, then we will use such remaining assets to pay the amounts of principal of, premium, if any, and accrued and unpaid interest on, the Notes and such other of our indebtedness and obligations that rank equally in right of payment with the Notes. If those assets are insufficient to pay in full the principal of, premium, if any, and interest on the Notes and such other indebtedness and obligations, those assets will be applicable ratably to the payment of such amounts owing with respect to the Notes and such other indebtedness and obligations.

In the event of our insolvency, bankruptcy, receivership, liquidation, or other marshalling of our assets and liabilities, if the holders of the Notes receive for any reason any payment on the Notes or other distributions of our assets with respect to the Notes before all of our senior indebtedness is paid in full, the holders of the Notes will be required to return that payment or distribution to the bankruptcy trustee, receiver, liquidating trustee, custodian, assignee, agent, or other person making payment of our assets for all our senior indebtedness remaining unpaid until all that senior indebtedness has been paid in full, after giving effect to any other concurrent payment or distribution to the holders of such senior indebtedness.

By reason of the above subordination in favor of the holders of our senior indebtedness, in the event of our bankruptcy or insolvency, holders of our senior indebtedness may receive more, ratably, and holders of the Notes may receive less, ratably, than our other creditors.

We have outstanding junior subordinated debentures that relate to outstanding trust preferred securities issued to certain capital trusts to which the Notes will rank senior in right of payment. In addition, we may incur other indebtedness and obligations, the terms of which may provide that such indebtedness ranks either equally with or junior in right of payment to the Notes or promissory notes, bonds, debentures, and other evidences of indebtedness of a type that includes the Notes. As discussed above, in the event of our insolvency, bankruptcy, receivership, liquidation, or other marshalling of our assets and liabilities, the indebtedness and obligations ranking equally with the Notes will participate ratably in any of our assets remaining after the payment in full of all of our senior indebtedness. In such circumstances, our indebtedness and other obligations junior in right of payment to the Notes, such as our junior subordinated debentures, will not be entitled to receive any payments until the Notes and all of our indebtedness and obligations ranking equally in right of payment to the Notes have been paid in full.

All liabilities of the Bank, including deposits, and our other subsidiaries, including each subsidiary's liabilities to general creditors arising during its ordinary course of business or otherwise, will be effectively senior in right of payment to the Notes to the extent of the assets of such subsidiary because, as a stockholder of the subsidiary, we do not have any rights to the assets of the subsidiary except if the subsidiary declares a dividend payable to us or if there are assets of the subsidiary remaining after it has discharged its liabilities to its creditors in connection with its liquidation. Over the term of the Notes, we will need to rely primarily on dividends paid to us by the Bank, which is a regulated financial institution, for the funds necessary to pay the interest on our outstanding debt obligations and to make dividends and other payments on our other securities outstanding now or in the future.

With respect to the payment of the principal of the Notes at their maturity, we may rely on the funds we receive from dividends paid to us by our subsidiaries, but will likely have to rely on the proceeds of borrowings and other securities we sell to pay the principal amount of the Notes.

Regulatory rules may restrict the Bank's ability to pay dividends or make other distributions to us or to provide funds to us by other means. As a result of the foregoing, with respect to the assets of each of our subsidiaries, our creditors (including the holders of the Notes) are structurally subordinated to the prior claims of

S-28

creditors of any such subsidiary, including the depositors of the Bank, except to the extent that we may be a creditor with recognized claims against any such subsidiary.

As discussed above, neither the Notes nor the Indenture contains any limitation on the amount of senior indebtedness or other obligations ranking senior to or equally with the indebtedness evidenced by the Notes that we, the Bank or any of our other subsidiaries may incur. Any indebtedness and liabilities of the Bank or our other subsidiaries is not a part of our senior indebtedness. The Notes will be structurally subordinate to all of the existing and future indebtedness and liabilities, including deposit liabilities, of our subsidiaries, including the Bank. As of June 30, 2026, on a consolidated basis, our outstanding deposits and other liabilities totaled approximately $18.7 billion, which includes approximately $18.6 billion of liabilities that rank structurally senior to the Notes. In addition, as of June 30, 2026, we had $13 million in indebtedness that would rank senior to the Notes, $29 million aggregate principal amount of indebtedness that would rank pari passu to the Notes, and $52 million aggregate principal amount of indebtedness related to existing junior subordinated debentures underlying outstanding trust preferred securities that would rank junior to the Notes.

Redemption

We may redeem the Notes, at our sole option, beginning with the Interest Payment Date of   ,      and on any date thereafter, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the date of redemption, subject to prior approval of the Federal Reserve, to the extent that such approval is then required under the rules of the Federal Reserve. If we elect to redeem the Notes, we will be required to notify the Trustee of the aggregate principal amount of Notes to be redeemed and the redemption date. Any such redemption may be subject to the satisfaction of one or more conditions precedent set forth in the applicable notice of redemption. If fewer than all of the Notes are to be redeemed, the selection of Notes to be redeemed will occur in accordance with the rules of DTC (or, in the case of any certificated Notes, by lot, on a pro rata basis or in such other manner the Trustee deems fair and appropriate unless otherwise required by law). The Notes are not subject to repayment at the option of the holders. We may also redeem the Notes at any time prior to their scheduled maturity, including prior to    , , at our sole option, upon or after the occurrence of any of the following:

(1) a "Tax Event," which is defined in the Indenture to mean the receipt by us of an opinion from independent tax counsel to the effect that (a) an amendment to or change (including any announced prospective amendment or change) in any law, treaty, statute, or code, 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"), (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, or (d) a threatened challenge asserted in writing in connection with an audit of our federal income tax returns or positions or a similar audit of any of our subsidiaries or a publicly known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes, in each case, occurring or becoming publicly known on or after the date of original issuance of the Notes, resulting in more than an insubstantial increase in the risk that the interest paid by us on the Notes is not, or within 90 days of receipt of such opinion of tax counsel, will not be, deductible by us, in whole or in part, for U.S. federal income tax purposes;

(2) a "Tier 2 Capital Event," which is defined in the Indenture to mean the receipt by us of an opinion from independent bank regulatory counsel to the effect that, as a result of (a) any amendment to, or change (including any announced prospective change) in, the laws or any regulations thereunder of the United States or any rules, guidelines, or policies of an applicable regulatory authority for the Corporation or (b) any official administrative pronouncement or judicial decision interpreting or applying such laws or

S-29

regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of original issuance of the Notes, the Notes do not constitute, or within 90 days of the date of such opinion will not constitute, Tier 2 capital (or its then equivalent if we were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve (or any successor regulatory authority with jurisdiction over bank holding companies), as then in effect and applicable to us; or

(3) our becoming required to register as an investment company pursuant to the Investment Company Act of 1940.

Any such redemption of the Notes will be at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the date of redemption. Notwithstanding the foregoing, installments of interest on any Notes that are due and payable on Interest Payment Dates falling on or prior to the applicable date of redemption will be payable on such Interest Payment Dates to the registered holders at the close of business on the relevant record dates in accordance with the Notes and the Indenture. Any such redemption may be subject to the satisfaction of one or more conditions precedent set forth in the applicable notice of redemption. Any redemption of the Notes would require prior approval of the Federal Reserve, to the extent that such approval is then required under the rules of the Federal Reserve.

Our election to redeem any of the Notes will be provided to the Trustee at least three business days prior to the requested date of delivery (or such shorter period as is satisfactory to the Trustee). In the case of any redemption, at least 10 days but no more than 60 days before the redemption date, the Corporation will send in accordance with the applicable procedures of the depositary (with a copy to the Trustee), or if the Notes are not then global securities the Corporation will mail, or cause to be mailed, a notice of redemption by first-class mail to each holder of Notes to be redeemed at such holder's registered address appearing on the register (with a copy to the Trustee).

In addition, subject to any required federal or state regulatory approvals, the Corporation may purchase or otherwise acquire the Notes, whether by open market purchases, negotiated transactions, private transactions, or otherwise, at any time or from time to time. A Note will not cease to be outstanding because the Corporation or an affiliate of the Corporation holds the Note, and if the Corporation purchases or otherwise acquires any Notes, it may, in its discretion, hold, resell, or cancel any of such Notes.

The Notes Are Intended to Qualify as Tier 2 Capital

We intend to treat the Notes as Tier 2 capital under the capital adequacy rules established by the Federal Reserve for bank holding companies, as the same may be amended or supplemented from time to time. The rules set forth specific criteria for instruments to qualify as Tier 2 capital. Among other things, the Notes must:

S-30

Events of Default; Limitation on Suits

Under the Indenture, an event of default will occur if we fail to pay accrued and unpaid interest on the Notes and any notes of the same series offered in the future and such failure continues for 90 days, we fail to pay principal of any notes of that series when due, whether at maturity or upon redemption, or upon our default in the performance, or breach, of any other covenant or warranty contained in the Indenture, other than a covenant added to the Indenture solely for the benefit of any other series of subordinated debt securities issued under the Indenture, and such default continues for 90 days after written notice as provided in the Indenture. In addition, an event of default will occur upon the entry of a decree or order for relief in respect of the Corporation or the Bank by a court having jurisdiction in the premises in an involuntary case or proceeding under any applicable bankruptcy, insolvency, or reorganization law, including Chapter 7 (liquidation) or Chapter 11 (reorganization) of the U.S. Bankruptcy Code, as now or hereafter in effect, and such decree or order continues unstayed and in effect for a period of 60 consecutive days or if we commence a voluntary case under any applicable bankruptcy, insolvency, or reorganization law, including under Chapter 7 (liquidation) or Chapter 11 (reorganization) of the U.S. Bankruptcy Code, as now or hereafter in effect, each of which events of default we refer to as an "insolvency event of default."

If an insolvency event of default occurs and is continuing, the principal amount and accrued and unpaid interest on the Notes will become immediately due and payable, without the need for any action on the part of the holders of the Notes or the Trustee, subject to the broad equity powers of a federal bankruptcy court and the determination by that court of the nature and status of the payment claims of the holders of the Notes.

Neither the Trustee nor the holders of the Notes will have the right to accelerate the maturity of the Notes in the case of our failure to pay the principal of, or interest on, the Notes or our nonperformance of any other covenant or warranty under the Notes or the Indenture. Nevertheless, during the continuation of such an event of default under the Notes, the Trustee may, subject to certain limitations and conditions, seek to enforce its rights and the rights of the holders of Notes to regularly scheduled payments of interest and the payment of principal at the scheduled maturity of the Notes, as well as the performance of any covenant or agreement in the Indenture. Any such rights to receive payment of such amounts under the Notes remain subject to the subordination provisions of the Notes as discussed above under "-Subordination of the Notes."

At any time after acceleration with respect to the Notes has occurred, but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in aggregate principal amount of outstanding Notes of the series of our subordinated notes which the Notes are a part and other affected series of securities issued under the Indenture, voting as one class, may waive all defaults and rescind and annul any acceleration occurring as to any and all securities of such series, including the Notes, but only if (1) we have paid or deposited with the Trustee a sum of money sufficient (a) to pay to the holders of the outstanding securities of all affected series of securities established under the Indenture, including the Notes, (i) all overdue installments of any interest that have become due otherwise than by such declaration of acceleration, (ii) the principal of and any premium that have become due otherwise than by such declaration of acceleration and, to the extent permitted by applicable law, interest thereon at the rate of interest borne by these securities, and (iii) to the extent permitted by applicable law, interest upon overdue installments of any interest, if any, that have become due otherwise than by such declaration of acceleration at the rate of interest borne by these securities and (b) to pay all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents and counsel and all other amounts due the Trustee; and (2) all events of default with respect to the Notes of the series of our subordinated notes which the Notes are a part and other affected series of securities issued under the Indenture, other than the nonpayment of the principal of, or any premium and interest on, the Notes that will have become due solely by such acceleration, will have been cured or waived as provided in the Indenture. Even in the event of an acceleration of the maturity of the

S-31

Notes upon the occurrence of an insolvency event, the rights of the holders of the Notes to receive payment of the principal of, and accrued and unpaid interest on, the Notes remain subject to the subordination provisions of the Notes as discussed above under "-Subordination of the Notes."

The Indenture provides that, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders of Notes unless such holders will have offered to the Trustee indemnity satisfactory to the Trustee against the costs, expenses and liabilities that may be incurred by it in complying with such request or direction. Subject to certain provisions in the Indenture, the holders of a majority in principal amount of the Notes outstanding from time to time 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 Notes.

Legal Defeasance and Covenant Defeasance

We may choose to either discharge our obligations under the Indenture and the Notes in a legal defeasance or to release ourselves from certain or all of our covenant restrictions under the Indenture and the Notes in a covenant defeasance. We may do so after we irrevocably deposit with the Trustee for the benefit of the holders of the Notes sufficient cash and/or U.S. government securities to pay the principal of (and premium, if any) and interest and any other sums due on the Maturity Date or a redemption date of the Notes. If we choose the legal defeasance option, the holders of the Notes will not be entitled to the benefits of the Indenture except for certain limited rights, including registration of transfer and exchange of Notes, replacement of lost, stolen, or mutilated Notes and the right to receive payments of the principal of (and premium, if any) and interest on such Notes when such payments are due.

We may discharge our obligations under the Indenture or release ourselves from covenant restrictions only if we meet certain requirements. Among other things, we must deliver to the Trustee an opinion of our legal counsel to the effect that beneficial owners of the Notes will not recognize income, gain, or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times, as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, this opinion must be based on either a ruling received from or published by the Internal Revenue Service (the "IRS") or a change in the applicable federal income tax law after the date hereof. We may not have a default under the Indenture or the Notes on the date of deposit. The discharge may not cause the Trustee to have a conflicting interest for purposes of the Trust Indenture Act and may not result in our becoming an investment company in violation of the Investment Company Act. The discharge may not violate any of our agreements to which we are a party or by which we are bound.

Any defeasance of the Notes pursuant to the Indenture will be subject to our obtaining the prior approval of the Federal Reserve and any additional requirements that the Federal Reserve may impose with respect to defeasance of the Notes. Notwithstanding the foregoing, if, due to a change in law, regulation, or policy subsequent to the issue date of the Notes the Federal Reserve does not require that defeasance of instruments be subject to Federal Reserve approval in order for the instrument to be accorded Tier 2 capital treatment, then no such approval of the Federal Reserve will be required for such defeasance.

Satisfaction and Discharge

We may discharge our obligations under the Indenture and the Notes (except for certain surviving rights of the Trustee and our obligations in connection therewith) if: (a) all outstanding Notes and all other outstanding notes issued under the Indenture (i) have been delivered for cancellation, or (ii) (1) have become due and payable, (2) will become due and payable at their stated maturity within one year, or (3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice and redemption by the Trustee (and in each case, we have irrevocably deposited with the Trustee an amount sufficient to pay and discharge the principal of (and premium, if any) and interest on all outstanding Notes and

S-32

any other sums due on the stated maturity date or redemption date, as the case may be); (b) we have paid all other sums payable by us under the Indenture; and (c) we have delivered an officer's certificate and opinion of counsel confirming that all conditions precedent with respect to the satisfaction and discharge of the Indenture with respect to the Notes have been satisfied.

Further Issuances

We may, from time to time, without notice to or the consent of the holders of the Notes, create and issue additional notes ranking equally with the Notes and with identical terms in all respects (except for the issue date, the offering price, the initial interest accrual date, and the first Interest Payment Date) in order that such additional notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption, or otherwise as the Notes, subject to the procedures of the DTC; provided however, that a separate CUSIP number will be issued for any such additional notes unless such additional notes are fungible with the Notes for U.S. federal income tax purposes.

The Trustee may conclusively rely upon officer's certificates, opinions, or other documents furnished to it under the Indenture and will have no responsibility to confirm or investigate the accuracy of mathematical calculations or other facts stated therein. The Trustee will have no responsibility for monitoring FMC's compliance with any of its covenants under the Indenture.

Effect of Benchmark Transition Event

If the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any floating rate interest period during the floating rate period, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during such floating rate interest period and all subsequent floating rate interest periods. In connection with the implementation of a Benchmark Replacement, the calculation agent will have the right to make Benchmark Replacement Conforming Changes from time to time.

As used herein:

"Benchmark Replacement" means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment for such Benchmark; provided that if (i) the calculation agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date or (ii) the then-current Benchmark is Three-Month Term SOFR and a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark with respect to Three-Month Term SOFR will be determined), then "Benchmark Replacement" means the first alternative set forth in the order below that can be determined by the calculation agent as of the Benchmark Replacement Date:

S-33

"Benchmark Replacement Adjustment" means the first alternative set forth in the order below that can be determined by the calculation agent as of the Benchmark Replacement Date:

"Benchmark Replacement Conforming Changes" means, with respect to any Benchmark Replacement, any technical, administrative, or operational changes (including, without limitation, changes to the definition of "floating rate interest period," timing and frequency of determining rates with respect to each floating rate interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the calculation agent determines may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the calculation agent determines that adoption of any portion of such market practice is not administratively feasible or if the calculation agent determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the calculation agent determines is reasonably necessary).

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

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:

S-34

"Compounded SOFR" means the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for this rate, and conventions for this rate being established by the calculation agent in accordance with:

For the avoidance of doubt, the calculation of Compounded SOFR will exclude the Benchmark Replacement Adjustment and the spread specified above.

"Interpolated Benchmark" with respect to the Benchmark means the rate determined by the calculation agent for the Corresponding Tenor by interpolating on a linear basis between: (i) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor, and (ii) the Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor.

"ISDA" means the International Swaps and Derivatives Association, Inc. or any successor.

"ISDA Definitions" means the 2021 ISDA Definitions published by ISDA, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

"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 to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor.

"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.

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

The terms "FRBNY's Website," "Reference Time," "Relevant Governmental Body," "SOFR" and "Term SOFR" have the meanings set forth under the heading "-Floating Rate Period" above.

Determinations and Decisions

The calculation agent (which may be us) is expressly authorized to make certain determinations, decisions, and elections under the terms of the Notes, including with respect to the use of Three-Month Term SOFR as the

S-35

Benchmark for the floating rate period and under the benchmark transition provisions. Any determination, decision, or election that may be made by us or by the calculation agent under the terms of the Notes, including any determination with respect to a tenor, rate, or adjustment or of the occurrence or non-occurrence of an event, circumstance, or date and any decision to take or refrain from taking any action or any selection:

If the calculation agent fails to make any determination, decision, or election that it is required to make under the terms of the applicable Notes, then we will make such determination, decision, or election on the same basis as described above. The indenture provides that the Trustee will have no liability relating to any delay caused by the calculation agent's failure to timely or appropriately determine the rate of interest borne by the Notes.

Modification of the Indenture

Article 10 of the Base Indenture will apply to the Notes. In addition, without the consent of any holders of Notes, the Corporation, and the Trustee, at any time and from time to time, may enter into one or more supplemental indentures to implement in accordance with the terms herein any Three-Month Term SOFR Conventions or any benchmark transition provisions after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred (or in anticipation thereof).

Calculation Agent

We will appoint a calculation agent for the Notes prior to the commencement of the floating rate period. We will act as the initial calculation agent.

Form, Denomination, Transfer, Exchange, and Book-Entry Procedures

The Notes offered hereby will be issued only in fully registered form, without interest coupons, and in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

The Notes offered hereby will be evidenced by a global note which will be deposited with, or on behalf of, DTC, or any successor thereto, and registered in the name of Cede & Co., or Cede, as nominee of DTC. Except as set forth below, record ownership of the global note may be transferred, in whole or in part, only to another nominee of DTC or to a successor of DTC or its nominee.

The global note will not be registered in the name of any person, or exchanged for Notes that are registered in the name of any person, other than DTC or its nominee, unless one of the following occurs:

S-36

In those circumstances, DTC will determine in whose names any securities issued in exchange for the global note will be registered. Any such Notes in certificated form will be issued in minimum denominations of $1,000 and multiples of $1,000 in excess thereof and may be transferred or exchanged only in such minimum denominations. DTC or its nominee will be considered the sole owner and holder of the global note for all purposes, and as a result:

The laws of some jurisdictions require that certain kinds of purchasers (for example, certain insurance companies) can only own securities in definitive (certificated) form. These laws may limit your ability to transfer your beneficial interests in the global note to these types of purchasers.

Only institutions (such as a securities broker or dealer) that have accounts with the DTC or its nominee (called "participants") and persons that may hold beneficial interests through participants (including through Euroclear Bank SA/NV or Clearstream Banking, société anonyme, as DTC participants) can own a beneficial interest in the global note. The only place where the ownership of beneficial interests in the global note will appear and the only way the transfer of those interests can be made will be on the records kept by DTC (for their participants' interests) and the records kept by those participants (for interests of persons held by participants on their behalf).

Secondary trading in bonds and notes of corporate issuers is generally settled in clearing-house (that is, next-day) funds. In contrast, beneficial interests in a global note usually trade in DTC's same-day funds settlement system, and settle in immediately available funds. We make no representations as to the effect that settlement in immediately available funds will have on trading activity in those beneficial interests.

We will make cash payments of interest on and principal of the global note to Cede, the nominee for DTC, as the registered owner of the global note. We will make these payments by wire transfer of immediately available funds on each payment date.

You may exchange or transfer the Notes at the corporate trust office of the trustee for the Notes or at any other office or agency maintained by us for those purposes. We will not require payment of a service charge for any transfer or exchange of the Notes, but we may require payment of a sum sufficient to cover any applicable tax or other governmental charge.

We have been informed that, with respect to any cash payment of interest on or principal of the global note, DTC's practice is to credit participants' accounts on the payment date with payments in amounts proportionate to their respective beneficial interests in the Notes represented by the global note as shown on DTC's records, unless DTC has reason to believe that it will not receive payment on that payment date. Payments by participants to owners of beneficial interests in Notes represented by the global note held through participants will be the responsibility of those participants, as is now the case with securities held for the accounts of customers registered in "street name."

We also understand that neither DTC nor Cede will consent or vote with respect to the Notes. We have been advised that under its usual procedures, DTC will mail an "omnibus proxy" to us as soon as possible after the record date. The omnibus proxy assigns Cede's consenting or voting rights to those participants to whose accounts the Notes are credited on the record date identified in a listing attached to the omnibus proxy.

S-37

Because DTC can only act on behalf of participants, who in turn act on behalf of indirect participants, the ability of a person having a beneficial interest in the principal amount represented by the global note to pledge the interest to persons or entities that do not participate in the DTC book-entry system, or otherwise take actions in respect of that interest, may be affected by the lack of a physical certificate evidencing its interest.

DTC has advised us that it will take any action permitted to be taken by a holder of Notes (including the presentation of Notes for exchange) only at the direction of one or more participants to whose account with DTC interests in the global note are credited and only in respect of such portion of the principal amount of the Notes represented by the global note as to which such participant has, or participants have, given such direction.

DTC has also advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code, as amended, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants. Participants include securities brokers and dealers, banks, trust companies, and clearing corporations and may include certain other organizations. Certain of such participants (or their representatives), together with other entities, own DTC. Indirect access to the DTC system is available to other entities such as banks, brokers, dealers, and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

The policies and procedures of DTC, which may change periodically, will apply to payments, transfers, exchanges, and other matters relating to beneficial interests in the global note. None of us, the Trustee, nor any of our respective agents has any responsibility or liability for any aspect of DTC's or any participants' records relating to beneficial interests in the global note, including for payments made on the global note, and none of us, the Trustee, nor any of our respective agents is responsible for maintaining, supervising, or reviewing any of those records.

Trustee

U.S. Bank Trust Company, National Association will act as Trustee under the Indenture. The Trustee has all of the duties and responsibilities specified under the Trust Indenture Act. The Trustee is not obligated to exercise any of its rights or powers under the Indenture at the request or direction of the holders of the Notes, unless the holders have offered to the Trustee security or indemnity satisfactory to the Trustee. From time to time, we, and one or more of our subsidiaries, may maintain deposit accounts and conduct other banking transactions, including lending transactions, with U.S. Bank Trust Company, National Association in the ordinary course of business. Additionally, we maintain banking relationships with U.S. Bank Trust Company, National Association and its affiliates in the ordinary course of business. These banking relationships include U.S. Bank Trust Company, National Association providing the Corporation with a revolving line of credit of up to $75 million. As of June 30, 2026, the Corporation's outstanding principal balance under the line of credit was zero.

Governing Law

The Notes and the Indenture will be governed by and will be construed in accordance with, the laws of the State of New York.

Notices

Notwithstanding any other provision of the Indenture or any Note, where the Indenture or any Note provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a

S-38

holder of a Note (whether by mail or otherwise), such notice will be sufficiently given if given to DTC (or its designee) pursuant to the applicable procedures from DTC or its designee, including by electronic mail in accordance with accepted practices at DTC.

S-39

CERTAIN ERISA AND BENEFIT PLAN CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase and holding of the Notes (including interests in Notes) by (1) employee benefit plans subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended, which we refer to as "ERISA", (2) plans, individual retirement accounts, and other arrangements subject to Section 4975 of the Code, (3) plans subject to any federal, state, local, non-U.S., or other laws or regulations that are similar to Title I of ERISA or Section 4975 of the Code, which we collectively refer to as "Similar Laws", and (4) entities whose underlying assets are considered to include "plan assets" of such employee benefit plans, plans, or arrangements for purposes of ERISA, the Code, or Similar Law (each of which we call a "Plan").

Each fiduciary of a Plan should consider the fiduciary standards of ERISA, to the extent applicable, or any applicable Similar Laws in the context of the Plan's particular circumstances before authorizing an investment in the Notes. Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification and the conflicts of interest requirements of ERISA, to the extent applicable, or any applicable Similar Laws and would be consistent with the documents and instruments governing the Plan.

In addition, Section 406 of ERISA and Section 4975 of the Code prohibit Plans subject to such provisions, which we call "ERISA Plans", from engaging in certain transactions involving "plan assets" with persons that are "parties in interest" under ERISA or "disqualified persons" under Section 4975 of the Code with respect to the ERISA Plan. A violation of these "prohibited transaction" rules may result in an excise tax for such persons or other liabilities under ERISA and/or Section 4975 of the Code, including recission of the transaction, unless exemptive relief is available under an applicable statutory or administrative exemption.

As a result of our business, we and certain of our affiliates may be considered parties in interest or disqualified persons with respect to many ERISA Plans. Prohibited transactions within the meaning of Section 406 of ERISA or Section 4975 of the Code could arise if the Notes (or interests therein) were acquired by an ERISA Plan with respect to which an underwriter or we or our affiliate is a party in interest or a disqualified person. For example, if any underwriter or we are a party in interest or disqualified person with respect to an investing ERISA Plan (either directly or, in our case, by reason of our ownership of our subsidiaries), the purchase of any Notes (or interests) by an ERISA Plan could result in a sale or exchange that is prohibited by Section 406(a)(1)(A) of ERISA and Section 4975(c)(1)(A) of the Code or lending of money or other extension of credit that is prohibited by Section 406(a)(1)(B) of ERISA and Section 4975(c) (1)(B) of the Code, unless exemptive relief were available under an applicable exemption (see below).

In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or PTCEs, that potentially may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase, holding or disposition of the Notes. Those class exemptions include:

In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provides an exemption for transactions between an ERISA Plan and a party in interest or disqualified person, provided that the party in interest or disqualified person is not a fiduciary (or an affiliate) who has or exercises any discretionary authority or control with respect to the investment of the ERISA Plan assets involved in the transaction or renders

S-40

investment advice with respect to those assets, and is a party in interest or disqualified person solely by reason of being a service provider to the ERISA Plan or having a relationship to a service provider to the ERISA Plan and provided, further that the ERISA Plan pays no more, nor receives no less, than adequate consideration in connection with the transaction (the so-called "service provider exemption"). Each of the above-described exemptions contain various requirements and limitations on their applicability. No assurance can be made that any such exemptions, or any other exemptions, will be available, or that all of the conditions of any such exemptions will be satisfied, with respect to transactions involving the Notes.

Employee benefit plans 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 Laws.

Because of the possibility that direct or indirect prohibited transactions or violations of Similar Laws could occur as a result of the purchase, holding or disposition of the Notes or interests therein by a Plan, the Notes and interests may not be purchased by any Plan, or any person investing the assets of any Plan, unless its purchase, holding, and disposition of the Notes or interests will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of any Similar Laws. Any purchaser or holder of the Notes or any interest in the Notes will be deemed to have represented by its purchase and holding of the Notes or interest that either:

Due to the complexity of these rules and the penalties imposed upon persons involved in non-exempt prohibited transactions, it is important that any person considering the purchase of the Notes or interest in a Note on behalf of or with the assets of any Plan consult with its counsel regarding the consequences under ERISA, the Code, and any applicable Similar Laws of the acquisition, ownership, and disposition of the Notes, whether any exemption would be applicable, and whether all conditions of such exemption would be satisfied such that the acquisition and holding of the Notes or interests by the Plan would be entitled to full exemptive relief thereunder.

Nothing herein will be construed as, and the sale of the Notes to a Plan is in no respect, a representation or advice by us or the underwriters (or any of our or their affiliates) as to whether any investment in the Notes would meet any or all of the relevant legal requirements with respect to investment by, or is appropriate or advisable for, Plans generally or any particular Plan. Each purchaser and holder of the Notes (including an interest in a Note) has the exclusive responsibility for ensuring that its purchase, holding and disposition of the Notes complies with the fiduciary responsibility rules of Title I of ERISA and does not violate the prohibited transaction rules of ERISA or Section 4975 of the Code or any applicable Similar Laws. Purchasers of any Notes (or interests therein) should consult and rely on their own advisors as to whether an investment in the Notes is suitable and advisable for the Plan.

The foregoing discussion is merely a summary and should not be construed as legal advice or as complete in all relevant respects.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

General

The following is a discussion of U.S. federal income tax considerations generally applicable to the ownership and disposition of the Notes by a U.S. holder or a non-U.S. holder (each as defined below) that purchases the Notes pursuant to and at the price indicated on the cover of this prospectus supplement and holds the Notes as "capital assets" (generally, property held for investment purposes) for U.S. federal income tax purposes. This discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the "Code"), U.S. Treasury Regulations promulgated thereunder, judicial decisions, and current administrative rulings and practice, all as in effect and available as of the date of this prospectus supplement and all of which are subject to differing interpretations or change, possibly with retroactive effect. There can be no assurance that the Internal Revenue Service (the "IRS") or a court will concur with the conclusions reached below.

This discussion does not discuss all aspects of U.S. federal income taxation which may be important to particular investors in light of their individual circumstances, such as investors subject to special tax rules (e.g., banks and other financial institutions, insurance companies, real estate investment trusts, broker-dealers, partnerships and their partners, tax-exempt organizations (including private foundations), qualified retirement plans, "controlled foreign corporations," "passive foreign investment companies," holders subject to the alternative minimum tax, and certain former citizens and former long-term residents of the United States), or to persons that will hold the Notes as part of a "straddle", synthetic security or "hedge", conversion transaction, constructive sale, or other integrated investment or risk reduction transaction, all of whom may be subject to tax rules that differ significantly from those summarized below. Furthermore, this discussion does not address any other U.S. federal tax considerations (e.g., estate or gift tax, the U.S. federal alternative minimum tax, or the Medicare tax on net investment income) or any state, local, or non-U.S. tax laws. Prospective investors are urged to consult their own tax advisors regarding the U.S. federal, state, local, and non-U.S. tax considerations applicable to them in their particular circumstances.

For the purposes of this summary, a "U.S. holder" is a beneficial owner of a Note that, for U.S. federal income tax purposes, is any of the following: (i) an individual who is a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created in, or organized under the laws of, the United States, any state thereof, or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income tax regardless of source, or (iv) a trust (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all of the substantial decisions of the trust or (B) that has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a domestic trust.

For purposes of this discussion, the term "non-U.S. holder" means a beneficial owner of a Note that is not a U.S. holder and is not a partnership or other entity treated as a partnership for U.S. federal income tax purposes.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Notes, the U.S. federal income tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Partnerships investing in the Notes and partners in such partnerships are urged to consult their own tax advisors as to the particular U.S. federal income tax considerations applicable to them.

Treatment of the Notes as Variable Rate Debt Instruments

As discussed under "Description of the Notes," the Notes will bear interest at an initial fixed rate during the fixed rate period and then bear interest at a floating rate per annum, reset quarterly, during the floating rate period. Under applicable Treasury Regulations, a debt instrument will qualify as a "variable rate debt instrument" if (a) its issue price does not exceed the total noncontingent principal payments due under the debt instrument by

S-42

more than a specified de minimis amount, (b) the debt instrument provides for stated interest, paid or compounded at least annually, at current value of a single fixed rate and one or more qualified floating rates, and (c) except as described in (a) above, does not provide for any principal payments that are contingent. A "qualified floating rate" is any variable rate where variations in the value of such rate can reasonably be expected to measure contemporaneous variations in the cost of newly borrowed funds in the currency in which the debt instrument is denominated. Under the foregoing definition, the Notes are expected to be treated as variable rate debt instruments for U.S. federal income tax purposes and the discussion below is based on this assumption.

Original Issue Discount and Qualified Stated Interest

It is anticipated, and this discussion assumes, that the issue price of the Notes will be equal to the Note's stated redemption price at maturity or, if the Note's issue price is less than its stated redemption price at maturity, the difference will be less than a specified de minimis amount (as defined in the applicable Treasury Regulations). If, however, the issue price of a Note is less than the Note's stated redemption price at maturity and the difference is equal to or greater than a specified de minimis amount (as defined in the applicable Treasury Regulations), then a U.S. holder generally will be required to include the difference in income as original issue discount as it accrues in accordance with a constant yield method.

The tax treatment of interest depends on whether such interest constitutes "qualified stated interest," referred to herein as "QSI." With respect to a debt instrument that provides for a single fixed rate and one or more qualified floating rates, QSI is determined by first converting the single fixed rate to an equivalent qualified floating rate, then converting each qualified floating rate to the applicable fixed rate substitute for the applicable interest accrual periods, and determining OID and QSI as if such instrument were a fixed rate instrument. In such case, QSI is generally the amount of interest that is payable at least annually at a single fixed rate. These calculations cannot be performed with certainty in advance of the issuance of the Notes as they will depend on the market conditions at the time of issuance. Based upon current market conditions and the manner in which the interest rates on the Notes are determined, we expect that all of the stated interest on the Notes will be treated as QSI and the Notes will be treated as having been issued with less than a specified de minimis amount of original issue discount.

The remainder of this discussion assumes that the stated interest on the Notes will be treated as QSI and the Notes will be treated as having been issued with less than a specified de minimis amount of original issue discount. Holders are urged to consult their own tax advisors regarding the tax consequences to them if the Notes are issued with original issue discount or if the stated interest is not treated as QSI.

Tax Considerations for U.S. Holders

Interest on the Notes

Generally, payments of stated interest on a Note will be taxable to a U.S. holder as ordinary income at the time they are received or accrued, depending on the U.S. holder's method of accounting for U.S. federal income tax purposes.

Sale, Exchange, Redemption or Other Taxable Disposition of the Notes

A U.S. holder generally will recognize gain or loss upon the sale, exchange, redemption, or other taxable disposition of a Note in an amount equal to the difference, if any, between the amount realized upon the sale, exchange, redemption, or other taxable disposition and the U.S. holder's adjusted tax basis in the Note. For these purposes, the amount realized does not include any amount attributable to accrued but unpaid interest, which will be taxed as described above under "-Interest on the Notes." Any gain or loss that a U.S. holder recognizes on a disposition of a Note will generally be capital gain or loss, except to the extent of any accrued interest relating to such U.S. holder's Notes required to be included in income, and will be long-term capital gain or loss if at the

S-43

time of this disposition a U.S. holder has held the Note for more than one year. Long-term capital gain of U.S. holders may be eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations under the Code.

Tax Considerations for Non-U.S. Holders

Payments of Interest

A non-U.S. holder will generally not be subject to U.S. federal income or withholding tax on payments of interest on the Notes provided that (1) such interest is not effectively connected with the conduct of a trade or business within the United States by the non-U.S. holder and (2) the non-U.S. holder (a) does not actually or constructively own 10% or more of the total combined voting power of all classes of stock of the Issuer entitled to vote, (b) is not a controlled foreign corporation related to the Issuer (within the meaning of the Code), and (c) certifies, under penalties of perjury, to the applicable withholding agent on IRS Forms W-8BEN or W-8BEN-E (or appropriate substitute form) that it is not a U.S. person and that no withholding is required pursuant to the Foreign Account Tax Compliance Act ("FATCA") (discussed below), and provides its name, address, and certain other required information or certain other certification requirements are satisfied.

If interest on the Notes is not effectively connected with the conduct of a trade or business in the United States by a non-U.S. holder but such non-U.S. holder cannot satisfy the other requirements outlined in the preceding paragraph, interest on the Notes will generally be subject to U.S. federal withholding tax (currently imposed at a 30% rate), unless the withholding tax rate is reduced or eliminated by an applicable treaty, and such non-U.S. holder is a qualified resident of the treaty country and complies with certain certification requirements.

If interest on the Notes is effectively connected with the conduct of a trade or business within the United States by a non-U.S. holder and, if required under an applicable treaty, such interest is attributable to a permanent establishment or fixed base within the United States, then the non-U.S. holder will generally be subject to U.S. federal income tax on the receipt or accrual of such interest on a net income basis in the same manner as if such holder were a U.S. holder and, in the case of a non-U.S. holder that is a foreign corporation, may also be subject to an additional branch profits tax (currently imposed at a rate of 30%, or a lower applicable treaty rate) on its effectively connected earnings and profits for the taxable year, subject to adjustments. Any such interest will not also be subject to U.S. federal withholding tax, however, if the non-U.S. holder timely provides the withholding agent a properly executed IRS Form W-8ECI in order to claim an exemption from U.S. federal withholding tax.

Sale, Exchange, Redemption, or Other Taxable Disposition of the Notes

A non-U.S. holder will generally not be subject to U.S. federal income tax (or any withholding thereof) with respect to gain, if any, recognized upon the sale, exchange, redemption, or other disposition of the Notes (other than any amount representing accrued and unpaid interest on the Note, which is subject to the rules discussed above under "-Payments of Interest") unless (1) the gain is effectively connected with the conduct of a trade or business within the United States by the non-U.S. holder and, if required under an applicable treaty, is attributable to a permanent establishment or fixed base of the non-U.S. holder within the United States, or (2) in the case of a non-U.S. holder that is an individual, such holder is present in the United States for 183 or more days in the taxable year in which the sale, exchange, redemption, or other disposition of the Notes occurs and certain other conditions are satisfied.

Gain that is effectively connected with the conduct of a trade or business in the United States will generally be subject to U.S. federal income tax on a net income basis (but not U.S. withholding tax), in the same manner as if the non-U.S. holder were a U.S. holder, and, in the case of a non-U.S. holder that is a foreign corporation, may also be subject to an additional branch profits tax (currently imposed at a rate of 30%, or a lower applicable treaty rate) on its effectively connected earnings and profits, subject to adjustments. An individual non-U.S. holder who is subject to U.S. federal income tax because the non-U.S. holder was present in the United States for

S-44

183 days or more during the year of sale, exchange, redemption, or other disposition of the Notes will be subject to a flat 30% tax on the gain derived from such sale, exchange, redemption, or other disposition, which may be offset by certain U.S.-source capital losses.

Information Reporting and Backup Withholding

In general, information reporting requirements will apply to payments of interest on the Notes and to the payment of proceeds from the sale or other disposition of a Note, and backup withholding (currently imposed at a rate of 24%) may apply to such payments unless the holder (i) is an exempt recipient or (ii) provides a correct taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred.

Information reporting and backup withholding generally will not apply to payments to a non-U.S. holder of interest on the Notes, or to the payment of the proceeds from the disposition of a Note, if the certification described above under "-Payments of Interest" is received, provided that the applicable withholding agent does not have actual knowledge or reason to know that the holder is a U.S. person.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a holder generally will be allowed as a credit against such holder's U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

FATCA Withholding

Pursuant to Sections 1471 through 1474 of the Code, commonly referred to as "FATCA," withholding at a rate of 30% will generally be required in certain circumstances on interest payable on Notes held by or through certain financial institutions (including investment funds), unless such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons or by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country, or other guidance, may modify these requirements. Accordingly, the entity through which the Notes are held will affect the determination of whether such withholding is required. Similarly, interest payable on the Notes held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will generally be subject to withholding at a rate of 30%, unless such entity either (i) certifies that it does not have any "substantial United States owners" or (ii) provides certain information regarding the entity's "substantial United States owners," which will, in turn, be provided to the U.S. Department of the Treasury. Although FATCA also would have imposed withholding on payments of gross proceeds from the sale or other disposition of the Notes, proposed U.S. Treasury Regulations (upon which taxpayers may rely until final Treasury Regulations are issued) eliminate FATCA withholding on payments of gross proceeds. We will not be required to pay any additional amounts with respect to amounts withheld. Prospective investors are urged to consult their own tax advisors regarding the possible implications of these rules on an investment in the Notes.

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

S-45

UNDERWRITING

We have entered into an underwriting agreement with Piper Sandler & Co., as representative of the underwriters listed below (collectively, the "underwriters") with respect to the Notes being offered pursuant to this prospectus supplement. Subject to certain conditions, each underwriter has agreed, severally and not jointly, to purchase the aggregate principal amount of Notes set forth next to its name in the following table.

The underwriting agreement provides that the obligations of the underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers' certificates and legal opinions and approval of certain legal matters by its counsel. The underwriting agreement provides that the underwriters have agreed, severally and not jointly, to purchase all of the Notes offered hereby if any of them 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 under certain circumstances. We and First Merchants Bank have agreed to indemnify the underwriters, jointly and severally, against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The Notes will constitute a new class of securities with no established trading market. The underwriters have advised us that, following the completion of this offering, they currently intend to make a market in the Notes as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and the underwriters may discontinue any market-making activities at any time without notice in their sole discretion. Accordingly, no assurance can be given as to the liquidity of the trading market for the Notes, that you will be able to sell any of the Notes held by you at a particular time or that the prices that you receive when you sell will be favorable.

The underwriters are offering the Notes offered hereby subject to their acceptance of such Notes from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel, or modify offers to the public and to reject orders in whole or in part.

Commission and Expenses

Notes sold by the underwriters to the public will be offered at the public offering price set forth on the cover of this prospectus supplement. Any Notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price not to exceed   % of the principal amount of the Notes. If all of the Notes are not sold at their applicable initial offering prices, the underwriters may change the offering prices and the other selling terms. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

S-46

The following table shows the public offering price, the underwriting discounts and commissions that we are to pay the underwriters, and the proceeds, before expenses, to us in connection with this offering (expressed as a percentage of the principal amount of the Notes offered hereby).

We estimate expenses payable by us in connection with this offering, other than, in each case, underwriting discounts and commissions, will be approximately $  . We have agreed to reimburse the underwriters up to $230,000 for certain legal and other expenses in connection with this offering. Such reimbursement is deemed underwriter compensation by the Financial Industry Regulatory Authority ("FINRA") under FINRA Rule 5110.

We expect that delivery of the Notes will be made against payment therefor on or about   , 2026, which will be the second business day following the date of pricing of the Notes, or "T+ .

No Listing

The Notes will not be listed on any securities exchange or included in any automated quotation system.

No Sale of Similar Securities

We have agreed with the underwriters that for a period from the date of the underwriting agreement through and including the closing date of the offering, we and our subsidiaries will not, without the prior consent of each of the underwriters, offer, sell, contract to sell, or otherwise dispose of any debt securities issued or guaranteed by us or any of our subsidiaries.

Stabilization

In connection with this offering of the Notes, the underwriters may engage in overallotment, stabilizing transactions, and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which create a short position for the underwriters. Stabilizing transactions involve bids to purchase the Notes in the open market for the purpose of pegging, fixing, or maintaining the price of the Notes. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the Notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue such activities at any time without notice.

Neither we nor any of the underwriters makes 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 makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Activities and Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing, and brokerage activities. The underwriters or their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for us and our affiliates, for which they received or will receive customary fees and expenses.

S-47

In the ordinary course of their various business activities, the underwriters and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities or instruments issued by us and our affiliates. If the underwriters or their affiliates have a lending relationship with us, they routinely hedge their credit exposure to us consistent with their customary risk management policies. The underwriters and their affiliates may 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 or the securities of our affiliates, including potentially the Notes offered hereby. Any such short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also communicate independent investment recommendations, market color or trading ideas or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

S-48

LEGAL MATTERS

Certain legal matters and the validity of the Notes offered hereby will be passed upon for FMC by Dentons Bingham Greenebaum LLP, Indianapolis, Indiana. Certain legal matters related to the offering will be passed upon for the underwriters by Dorsey & Whitney LLP, Seattle, Washington.

SECURITIES WE MAY OFFER

We may use this prospectus to offer securities in one or more offerings. A prospectus supplement, which we will provide each time we offer securities, will describe the amounts, prices and detailed terms of the securities, may describe risks associated with an investment in the securities, and will describe the particular material terms of the offered securities. If indicated in the applicable prospectus supplement, the terms of the offered securities may differ from the terms summarized in this prospectus. We will also include in the prospectus supplement, where applicable, information about material United States federal income tax considerations relating to the securities and the securities exchange, if any, on which the securities will be listed. Terms used in this prospectus will have the meanings described in this prospectus unless otherwise specified. The securities of each class as described in this prospectus may also be offered and sold, from time to time, by one or more selling security holders to be identified in the future. The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize certain material terms and provisions of the various types of securities that we or selling security holders may offer and do not contain all of the information that may be useful or important to you. You should refer to the provisions of the actual documents whose terms are summarized herein and in the applicable prospectus supplement because those documents, and not the summaries, define your rights as holders of the relevant securities. The forms of these documents will be filed with the SEC and will be available as described under the heading "Where You Can Find More Information."

We may sell the securities to or through underwriters, dealers or agents or directly to purchasers. We, as well as any agents acting on our behalf, reserve the sole right to accept or reject, in whole or in part, any proposed purchase of our securities. Each prospectus supplement will set forth the names of any underwriters, dealers or agents involved in the sale of our securities described in that prospectus supplement and any applicable fee, commission or discount arrangements with them. We may issue securities in book-entry form through one or more depositaries, such as The Depository Trust Company, named in the applicable prospectus supplement. Each sale of a security in book-entry form will settle in immediately available funds through the applicable depositary, unless otherwise stated. We will issue the securities in registered form, without coupons.

This prospectus may not be used to sell securities unless accompanied by the applicable prospectus supplement. If any securities are to be listed on a securities exchange, the applicable prospectus supplement will state that information.

Warrants may be offered independently, together with other securities offered by any prospectus supplement, or through a dividend or other distribution to shareholders and may be attached to or separate from other securities. In a prospectus supplement, we will inform you of the exercise price and other specific terms of the warrants, including whether our or your obligations, if any, under any warrants may be satisfied by delivering or purchasing the underlying securities or their cash value.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock, certain provisions of our articles of incorporation and bylaws and certain provisions of Indiana law is a summary. The following description of the material terms of our capital stock is only a summary. The summary does not purport to be exhaustive and is qualified in its entirety by reference to our articles of incorporation, bylaws and the Indiana Business Corporation Law (the "IBCL"), as well as any other documents referenced in this summary and from which this summary is derived. Copies of our articles of incorporation and our bylaws have been filed with the SEC and are filed as exhibits to the registration statement of which this prospectus forms a part.

Common Stock

Authorized Common Stock

The total number of shares of common stock that we are authorized to issue is 100,000,000, all with no par value. Our common stock is listed on the Nasdaq Global Select Market under the symbol "FRME." As such, the holders of our common stock are generally not restricted on sales of their shares.

General

Voting Rights. Each share of our common stock is entitled to one vote. Directors are elected by a plurality of the votes cast by the shares entitled to vote in an election at a shareholder's meeting at which a quorum is present. Shareholders do not have a right to cumulate their votes for directors. The affirmative vote of a majority of the shares present and voting at a meeting of shareholders, in person or by proxy, is required for approval of all items submitted to the shareholders for consideration other than (i) the election of directors, as described above, which is based on a plurality of votes cast, (ii) certain amendments to our articles of incorporation, as described below under "Articles of Incorporation and Bylaw Amendments," which require a greater percentage, and (iii) certain transactions involving one or more shareholders owning, directly or indirectly, not less than ten percent (10%) of our voting shares (see "Indiana Law and Certain Provisions of Our Articles of Incorporation; Anti-takeover Measures" below) or a liquidation or dissolution of us or any of our material subsidiaries, which, in such cases, requires the affirmative vote of the holders of not less than three-fourths (3/4) of our voting shares.

Dividend Rights. The holders of our common stock are entitled to dividends and other distributions when, as and if declared by our board of directors.

Generally, we may not pay a dividend if, after giving effect to the dividend:

Our principal source of funds for dividend payments to shareholders is dividends received from First Merchants Bank, our wholly-owned bank subsidiary. Banking regulations limit the maximum amount of dividends that a bank may pay without requesting prior approval of regulatory agencies. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to a bank's retained net income (as defined in the regulations) for the current year plus those for the previous two years, subject to the capital requirements described above.

First Merchants Bank will ordinarily be restricted to paying dividends in a lesser amount to us than is legally permissible because of the need for banks to maintain adequate capital consistent with the capital adequacy guidelines promulgated by the banks' principal federal regulatory authorities. If a bank's capital levels are deemed inadequate by the regulatory authorities, payment of dividends to its parent holding company may be prohibited. First Merchants Bank is not currently subject to such a restriction.

11

Redemption. Under Indiana law, we may only redeem or acquire shares of our common stock with funds legally available therefor, and shares so acquired constitute authorized but unissued shares. We may not redeem or acquire our shares of common stock if, after such redemption, we would not be able to pay our debts as they become due. Additionally, we may not redeem our shares if our total assets would be less than the sum of our total liabilities plus preferential rights of shareholders payable upon dissolution.

Liquidation Rights. In the event of any liquidation or dissolution of us, our shareholders are entitled to receive pro rata, according to the number of shares held, any assets distributable to shareholders, subject to the payment of our liabilities and any rights of creditors and holders of shares of our preferred stock then outstanding.

Preemptive Rights. Our articles of incorporation do not provide for preemptive rights for shareholders to subscribe for any new or additional shares of common stock.

Articles of Incorporation and Bylaw Amendments. Indiana law generally requires shareholder approval for most amendments to a corporation's articles of incorporation by a majority of a quorum at a shareholder's meeting (and, in certain cases, a majority of all shares held by any voting group entitled to vote). However, Indiana law permits a corporation in its articles of incorporation to specify a higher shareholder vote requirement for certain amendments. Our articles of incorporation require (i) the affirmative vote of three-fourths (3/4) of our outstanding shares of stock entitled to vote for an amendment to certain significant provisions of the articles of incorporation (see "Removal of Directors" and "Classification of the Board of Directors" below), and (ii) a majority of our outstanding shares for all other amendments.

Unless otherwise provided in the bylaws or in the articles of incorporation, our board of directors, by a majority vote of the actual number of directors elected and qualified, may from time to time make, alter, amend or repeal the bylaws.

Removal of Directors. Our articles of incorporation and bylaws provide that any director or all directors may be removed, with or without cause, at a meeting of shareholders upon the vote of the holders of not less than two-thirds (2/3) of the outstanding shares of capital stock entitled to vote on the election of directors. However, if two-thirds (2/3) of the entire board of directors recommends removal of a director to the shareholders, then such director may be removed by the affirmative vote of the holders of at least a majority of the outstanding shares of capital stock entitled to vote on the election of directors at a shareholders meeting. Amendment of these provisions of our articles of incorporation requires the affirmative vote of three-fourths (3/4) of our outstanding shares of stock entitled to vote on such amendment. A two-thirds (2/3) vote of the entire board of directors is required to amend such provisions of our bylaws.

Classification of the Board of Directors. Our articles of incorporation and bylaws provide that the directors of the board of directors shall be divided into three classes, with the number of directors in each class being as nearly equal as possible and the term for one class expiring at each annual meeting of shareholders (i.e., directors generally serve three-year staggered terms). The directors in each class are eligible for re-election to a new term by the shareholders at the annual meeting held in the year in which the term for their class expires. Amendment of these provisions of our articles of incorporation requires the affirmative vote of three-fourths (3/4) of our outstanding shares of stock entitled to vote on such amendment. A two-thirds (2/3) vote of the entire board of directors is required to amend such provisions of our bylaws. Commencing with the annual meeting of shareholders to be held in 2027, the classification of our board of directors shall terminate and all directors shall, as of such meeting and thereafter, be elected for a one-year term expiring at the next annual meeting of shareholders and until their successors are elected and qualified.

Vacancies occurring between annual meetings caused by a director's resignation, death or other incapacity, or by an increase in the number of directors, may be filled by a majority vote of the remaining members of the board of directors until our next annual meeting of shareholders.

As stated above, our shareholders do not have cumulative voting rights in the election of directors.

12

Preferred Stock

Authorized Preferred Stock

Our authorized preferred stock consists of 500,000 shares of preferred stock, without par value. As of June 30, 2026, 10,000 shares of preferred stock were issued and outstanding, comprised of 10,000 shares of 7.50% Non-Cumulative Perpetual Preferred Stock, Series A.

General

Under our articles of incorporation and the IBCL, preferred stock may be issued from time to time in one or more series, upon board authorization and without shareholder approval. Within certain legal limits, our board of directors is authorized to determine the terms of any series of preferred stock, including:

As a result, our board of directors, without shareholder approval, could authorize preferred stock to be issued with voting, conversion and other rights that could adversely affect the voting power and other rights of common shareholders or other outstanding series of preferred stock.

Each series of preferred stock will have the dividend, liquidation, redemption and voting rights described below unless otherwise described in a prospectus supplement pertaining to a specific series of preferred stock.

The applicable prospectus supplement will describe the following terms of the series of preferred stock in respect of which this prospectus is being delivered:

Shares of our preferred stock, when issued against full payment of the purchase price, will be validly issued, fully paid and non-assessable.

When appropriate, the applicable prospectus supplement will describe the United States federal income tax considerations relevant to the preferred stock.

13

Rank. Each series of preferred stock will, with respect to dividend rights and rights upon our liquidation, dissolution or winding up, rank prior to common stock. The rank of each separate series of preferred stock will be described in the applicable prospectus supplement, but all shares of each series will be of equal rank with each other.

Dividends. Holders of each series of preferred stock will be entitled to receive, when, as and if our board of directors declares, cash dividends, payable at the dates and at the rates per share as described in the applicable prospectus supplement. Those rates may be fixed, variable or both.

Dividends may be cumulative or non-cumulative, as described in the applicable prospectus supplement. If dividends on a series of preferred stock are non-cumulative and if our board of directors fails to declare a dividend for a dividend period for that series, then holders of that preferred stock will have no right to receive a dividend for that dividend period, and we will have no obligation to pay the dividend for that period, whether or not dividends are declared for any future dividend payment dates. If dividends on a series of preferred stock are cumulative, the dividends on those shares will accrue from and after the date mentioned in the applicable prospectus supplement.

Redemption. The terms on which any series of preferred stock may be redeemed will be set forth in the applicable prospectus supplement. All shares of preferred stock which we redeem, purchase or acquire, including shares surrendered for conversion or exchange, will be retired and restored to the status of authorized but unissued shares, but may be reissued only as a part of the preferred stock other than the series of which they were originally a part.

Liquidation. In the event of our voluntary or involuntary liquidation, dissolution or winding up, preferred shareholders of any particular series will be entitled, subject to creditors' rights and holders of any series of preferred stock ranking senior as to liquidation rights, but before any distribution to common shareholders or holders of any series of preferred stock ranking junior as to liquidation rights, to receive a liquidating distribution in the amount of the liquidation preference, if any, per share as mentioned in the applicable prospectus supplement, plus accrued and unpaid dividends for the current dividend period. This would include any accumulation of unpaid dividends for prior dividend periods, if dividends on that series of preferred stock are cumulative. If the amounts available for distribution upon our liquidation, dissolution or winding up are not sufficient to satisfy the full liquidation rights of all the outstanding preferred stock of that series and all stock ranking equal to that series of preferred stock, then the holders of each series of that stock will share ratably in any distribution of assets in proportion to the full respective preferential amount, which may include accumulated dividends, to which they are entitled. After the full amount of the liquidation preference is paid, the holders of preferred stock will not be entitled to any further participation in any distribution of our assets.

Voting. The voting rights of preferred stock of any series will be described in the applicable prospectus supplement. Under Indiana law, regardless of whether a class or a series of shares is granted voting rights by the terms of our articles of incorporation, the shareholders of that class or series are entitled to vote as a separate voting group, or together with other similarly affected series, on certain amendments to our articles of incorporation and certain other fundamental changes that directly affect that class or series.

Under regulations of the Board of Governors of the Federal Reserve System the ("Federal Reserve Board"), if the holders of any series of preferred stock become entitled to vote for the election of directors because dividends on that series are in arrears, that series may then be deemed a "class of voting securities," and a holder of 25% or more of that series (or a holder of 5% or more if it otherwise exercises a "controlling influence" over First Merchants) may then be subject to regulation as a bank holding company. In addition, in that event:

14

Conversion or Exchange. The terms on which preferred stock of any series may be converted into or exchanged for another class or series of securities will be described in the applicable prospectus supplement.

Other Rights. The shares of a series of preferred stock may have the preferences, voting powers or relative, participating, optional or other special rights as may be described in the applicable prospectus supplement, our articles of incorporation, or as otherwise required by law. The holders of preferred stock will not have any preemptive rights to subscribe to any of our securities.

Title. First Merchants, any transfer agent and registrar for a series of preferred stock, and any of their agents may treat the registered owner of that preferred stock as the absolute owner of that stock, whether or not any payment for that preferred stock shall be overdue and despite any notice to the contrary, for any purpose.

Transfer Agent and Registrar. Unless the applicable prospectus supplement specifies otherwise, Broadridge Corporate Issuer Solutions, Inc. will be the transfer agent, registrar and dividend disbursement agent for each series of preferred stock.

Indiana Law and Certain Provisions of Our Articles of Incorporation; Anti-takeover Measures

Articles of Incorporation

Our articles of incorporation currently authorize the issuance of 100,000,000 shares of common stock and 500,000 shares of preferred stock. Within the limits of applicable law and the listing rules of the Nasdaq Global Select Market, these shares are available to be issued, without prior shareholder approval, with relative rights, privileges and preferences determined by our board of directors. The board could therefore authorize preferred stock with voting, conversion or other rights that could adversely affect the voting power and other rights of common shareholders or other outstanding preferred stock.

Our articles of incorporation also provide that the affirmative vote of holders of not less than three-fourths (3/4) of the voting shares is required for certain business combinations involving a 10% shareholder, including certain mergers, dispositions of material assets, liquidations or dissolutions, recapitalizations and other transactions that increase a 10% shareholder's proportionate ownership.

Before approval of a business combination, the board of directors must evaluate all relevant factors and issues and report its conclusion to shareholders. Those factors include the impact of the business combination on the communities in which we or our subsidiaries conduct business, employees, suppliers and customers, as well as any other financial or non-financial factors the board deems relevant.

Any director may be removed, with or without cause, by the affirmative vote of holders of not less than two-thirds (2/3) of the outstanding shares entitled to vote on the election of directors. If the board of directors, by an affirmative vote of at least two-thirds (2/3) of the entire board, recommends removal, the removal may be effected by the affirmative vote of holders of a majority of those shares.

No amendment may repeal, modify, amend, alter or diminish the provisions of Article V, Section 1, Section 1 of Article VII, Sections 4, 11 or 12 of Article IX, or Article X of our articles of incorporation without the affirmative vote of three-fourths (3/4) of the outstanding shares entitled to vote on the amendment.

These provisions in our articles of incorporation are designed to encourage potential acquirers to negotiate with our board of directors and to preserve for shareholders our value in a takeover attempt. These provisions

15

reduce the likelihood that a potential acquirer who is unwilling to pay a market premium determined by the board to be sufficient will attempt to acquire shares of our common stock by means of an open market accumulation, front-end loaded tender offer or other coercive or unfair takeover tactic.

Indiana Law

Chapters 42 and 43 of the IBCL, which are applicable to us, may be deemed to have certain anti-takeover effects by prescribing, in the case of Chapter 42, certain voting requirements in instances in which a person acquires our shares in excess of certain thresholds or proscribing, in the case of Chapter 43, certain transactions between the us and an "interested stockholder" (defined generally as a person beneficially owning 10% or more of a corporation's outstanding voting stock) during the five year period following the time such person became an interested stockholder.

In addition, Chapter 35 of the IBCL provides that in taking or declining to take any action, or in making or declining to make any recommendation to the shareholders of the corporation with respect to any matter, a board of directors may, in its discretion, consider both the short term and long term best interests of the corporation, taking into account, and weighing as the directors deem appropriate, the effects thereof on the corporation's shareholders and the other corporate constituent groups and interests, as well as any other factors deemed pertinent by the directors. As a result, by expanding the factors that may be considered relevant by the directors in assessing a takeover proposal, this provision could be deemed to have certain anti-takeover effects.

Banking Holding Company Act

The Bank Holding Company Act generally would prohibit any company that, together with its affiliates, is not solely engaged in activities that are permissible for a bank holding company or a financial holding company from acquiring control of us. For these purposes, "control" is generally defined as ownership, control or the ability to vote 25% or more of any class of voting stock of, control of the election of a majority of the directors of or other exercise of a controlling influence over a bank holding company. In addition, any existing bank holding company would need the prior approval of the Federal Reserve before acquiring more than 5% of our voting stock. The Change in Bank Control Act of 1978, as amended, prohibits a person or group of persons from acquiring control of a bank holding company unless the Federal Reserve has been notified and has not objected to the transaction. Under a rebuttable presumption established by regulations of the Federal Reserve, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as us, is presumed to constitute acquisition of control of the bank holding company for purposes of the Change in Bank Control Act of 1978.

16

DESCRIPTION OF DEPOSITARY SHARES

The depositary shares will be issued under deposit agreements to be entered into between us and a bank or trust company, as depositary, all to be set forth in the applicable prospectus supplement relating to any or all depositary shares in respect of which this prospectus is being delivered. We will file a copy of the deposit agreement and the depositary receipt with the SEC each time we issue a series of depositary shares, and these depositary receipts and deposit agreements will be incorporated by reference into the registration statement of which this prospectus forms a part.

General

If we elect to offer fractional interests in shares of preferred stock, we will provide for the issuance by a depositary to the public of receipts for depositary shares. Each depositary share will represent fractional interests of preferred stock. We will deposit the shares of preferred stock underlying the depositary shares under a deposit agreement between us and a bank or trust company selected by us. The bank or trust company must have its principal office in the United States and a combined capital and surplus of at least $50 million. The depositary receipts will evidence the depositary shares issued under the deposit agreement.

The deposit agreement will contain terms applicable to the holders of depositary shares in addition to the terms stated in the depositary receipts. Each owner of depositary shares will be entitled to all the rights and preferences of the preferred stock underlying the depositary shares in proportion to the applicable fractional interest in the underlying shares of preferred stock. The depositary will issue the depositary receipts to individuals purchasing the fractional interests in shares of the related preferred stock according to the terms of the offering described in a prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the entitled record holders of depositary shares in proportion to the number of depositary shares that the holder owns on the relevant record date. The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent. The depositary will add the undistributed balance to and treat it as part of the next sum received by the depositary for distribution to holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the entitled record holders of depositary shares, in proportion, insofar as possible, to the number of depositary shares owned by the holders, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution. If this occurs, the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to the holders. The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Conversion, Exchange and Redemption

If any series of preferred stock underlying the depositary shares may be converted or exchanged, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares represented by the depositary receipts.

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem, at the same time, the number of depositary shares representing the preferred stock. The depositary will redeem the depositary shares from the proceeds it receives from the corresponding redemption, in whole or in part, of the applicable series of preferred stock. The depositary will mail a notice of redemption to the record holders of the

17

depositary shares that are to be redeemed between 30 and 60 days before the date fixed for redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share on the applicable series of preferred stock. If less than all the depositary shares are to be redeemed, the depositary will select which shares to be redeemed by lot, proportionate allocation or another method.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will end, except the right to receive money, securities or other property payable upon redemption.

Voting

When the depositary receives notice of a meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the particulars of the meeting to the record holders of the depositary shares. Each record holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder's depositary shares. The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions. The depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock. We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Record Date

Whenever (1) any cash dividend or other cash distribution will become payable, any distribution other than cash will be made, or any rights, preferences or privileges will be offered with respect to the preferred stock, or (2) the depositary receives notice of any meeting at which holders of preferred stock are entitled to vote or of which holders of preferred stock are entitled to notice, or of the mandatory conversion of or any election on our part to call for the redemption of any preferred stock, the depositary will in each instance fix a record date (which will be the same as the record date for the preferred stock) for the determination of the holders of depositary receipts (x) who will be entitled to receive such dividend, distribution, rights, preferences or privileges or the net proceeds of the sale thereof or (y) who will be entitled to give instructions for the exercise of voting rights at any such meeting or to receive notice of such meeting or of such redemption or conversion, subject to the provisions of the deposit agreement.

Amendments

We and the depositary may agree to amend the deposit agreement and the depositary receipt evidencing the depositary shares. Any amendment that (1) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or (2) otherwise prejudices any substantial existing right of holders of depositary shares, will not take effect until 30 days after the depositary has mailed notice of the amendment to the record holders of depositary shares. Any holder of depositary shares that continues to hold its shares at the end of the 30-day period will be deemed to have agreed to the amendment.

Termination

We may direct the depositary to terminate the deposit agreement by mailing a notice of termination to holders of depositary shares at least 30 days before termination. In addition, a deposit agreement will automatically terminate if:

18

The depositary may likewise terminate the deposit agreement if at any time 60 days have expired after the depositary has delivered to us a written notice of its election to resign and a successor depositary has not been appointed and accepted its appointment. If any depositary receipts remain outstanding after the date of termination, the depositary thereafter will discontinue the transfer of depositary receipts, will suspend the distribution of dividends to the holders thereof, and will not give any further notices (other than notice of such termination) or perform any further acts under the deposit agreement except as provided below and except that the depositary will continue (1) to collect dividends on the preferred stock and any other distributions with respect thereto and (2) to deliver the preferred stock together with such dividends and distributions and the net proceeds of any sales of rights, preferences, privileges or other property, without liability for interest thereon, in exchange for depositary receipts surrendered. At any time after the expiration of two years from the date of termination, the depositary may sell the preferred stock then held by it at public or private sales, at such place or places and upon such terms as it deems proper and may thereafter hold the net proceeds of any such sale, together with any money and other property then held by it, without liability for interest thereon, for the pro rata benefit of the holders of depositary receipts that have not been surrendered.

Payment of Fees and Expenses

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

Resignation and Removal of Depositary

At any time, the depositary may resign by delivering notice to us, and we may remove the depositary. Resignations or removals will take effect upon the appointment of a successor depositary and its acceptance of the appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million.

Reports

The depositary will forward to the holders of depositary shares all reports and communications from us that are delivered to the depositary and that we are required by law, the rules of an applicable securities exchange or our articles of incorporation to furnish to the holders of the preferred stock. Neither we nor the depositary will be liable if the depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. The deposit agreement limits our obligations and the depositary's obligations to performance in good faith of the duties stated in the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding connected with any depositary shares or preferred stock unless the holders of depositary shares requesting us to do so furnish us with satisfactory indemnity. . In performing our obligations, we and the depositary may rely upon the written advice of our counsel or accountants, on any information that competent people provide to us and on documents that we believe are genuine.

DESCRIPTION OF DEBT SECURITIES

We have summarized below general terms and conditions of the debt securities that we will offer and sell pursuant to this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms and conditions of the series in a prospectus supplement to this prospectus. We will also indicate in the applicable prospectus supplement whether the general terms and conditions described in this prospectus apply to the series of debt securities. The terms and conditions of the debt securities of a series may be different in one or more respects from the terms and conditions described below. If so, those differences will be described in the applicable prospectus supplement.

We will issue the debt securities in one or more series under either a senior indenture or a subordinated indenture, in each case between us and a trustee as identified in the applicable prospectus supplement. The following description of provisions of the indentures does not purport to be complete and is subject to, and qualified in its entirety by reference to, the indentures, each of which has been filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part. A form of each debt security, any future supplemental indenture or similar document also will be so filed. You should read the indentures and any supplemental indenture or similar document because they, and not this description, define your rights as holder of our debt securities. All capitalized terms have the meanings specified in the indentures.

For purposes of this section of this prospectus, references to "Corporation," "we," "us" and "our" are to First Merchants Corporation and not to any of its subsidiaries.

General

We may issue, from time to time, debt securities, in one or more series, which will consist of either senior debt ("Senior Debt Securities") or subordinated debt ("Subordinated Debt Securities"). Debt securities, whether senior or subordinated, may be issued as convertible debt securities or exchangeable debt securities. Senior Debt Securities will be issued under an indenture, referred to as the "senior indenture," between us and a senior indenture trustee to be named in the applicable prospectus supplement. Subordinated Debt Securities will be issued under a separate indenture, referred to as the "subordinated indenture," between us and a subordinated indenture trustee to be named in the applicable prospectus supplement. The senior indenture and the subordinated indenture are sometimes collectively referred to in this prospectus as the "indentures." The indentures will be subject to and governed by the Trust Indenture Act of 1939. A form of each of these indentures is included as an exhibit to the registration statement of which this prospectus is a part.

The following briefly describes the general terms and provisions of the debt securities which may be offered and the indentures governing them. The particular terms of the debt securities offered, and the extent, if any, to which these general provisions may apply to the debt securities so offered, will be described in more detail in the applicable prospectus supplement relating to those securities. The following descriptions of the indentures are not complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the respective indentures.

Unless we give you different information in the prospectus supplement, the Senior Debt Securities will be unsubordinated obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. Payments on the Subordinated Debt Securities will be subordinated to the prior payment in full of all of our Senior Indebtedness (as described in the applicable prospectus supplement).

Neither indenture limits the amount of debt securities that we may issue. We may, without the consent of the holders of the debt securities of any series, issue additional debt securities ranking equally with, and otherwise similar in all respects to, the debt securities of the series (except for any differences in the issue price and, if applicable, the initial interest accrual date and interest payment date) so that those additional debt securities will be consolidated and form a single series with the debt securities of the series previously offered and sold;

20

provided that if the additional debt securities are not fungible with the debt securities of the series previously offered or sold for U.S. federal income tax purposes, the additional debt securities will have a separate CUSIP or other identifying number.

The indentures provide that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit designated by us. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indentures, the terms of the indentures do not contain any covenants or other provisions designed to afford holders of any debt securities protection with respect to our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indentures as "discount securities," which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may, for U.S. federal income tax purposes, be treated as if they were issued with "original issue discount," because of interest payment and other characteristics. Special U.S. federal income tax considerations applicable to debt securities issued with original issue discount will be described in more detail in any applicable prospectus supplement.

Provisions of the Indentures

The applicable prospectus supplement for a series of debt securities that we issue will describe, among other things, the following terms of the offered debt securities:

21

The applicable prospectus supplement will set forth certain U.S. federal income tax considerations for holders of any debt securities and the securities exchange or quotation system on which any debt securities are listed or quoted, if any.

Debt securities issued by us will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries, except to the extent any such subsidiary guarantees or is otherwise obligated to make payment on such debt securities.

Conversion or Exchange Rights

Debt securities may be convertible into or exchangeable for other securities or property of ours. The terms and conditions of conversion or exchange will be set forth in the applicable prospectus supplement. The terms will include, among others, the following:

Consolidation, Merger or Sale

The indentures provide that we may not consolidate with or merge with or into, or sell or convey all or substantially all of our assets to any person, firm or corporation, unless:

Events of Default

For any series of debt securities, in addition to any event of default described in the prospectus supplement applicable to that series, an event of default will include the following events:

22

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indentures.

If an event of default with respect to any outstanding debt securities occurs and is continuing, then the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series may, by written notice to us (and to the trustee if given by the holders), accelerate the payment of the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) on all debt securities of that series. Following acceleration, payments on our subordinated debt securities, if any, will be subject to the subordination provisions described above under "Subordinated Debt Securities." At any time after acceleration with respect to debt securities of any series, but before the trustee has obtained a court judgment or decree for payment of the amounts due, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration of all events of default. The prospectus supplement relating to any series of debt securities that are discount securities will contain particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

Obligations of the Trustee

The indentures provide that the trustee will be under no obligation to exercise any rights or powers under such indenture at the request of any holder of outstanding debt securities unless the trustee is indemnified against any costs, liability or expense.

Remedies

Subject to certain rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

No holder of any debt security may institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

23

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

Under the indentures, we must furnish the trustee a statement as to compliance with such indenture within 120 days after the end of our fiscal year (beginning with the fiscal year ending immediately following the execution of such indenture). The indentures provide that, other than with respect to payment defaults, the trustee may withhold notice to the holders of debt securities of any series of a default or event of default if it in good faith determines that withholding notice is in the interests of the holders of those debt securities.

Registered Global Securities

We may issue the debt securities of a series in whole or in part in the form of one or more fully registered global securities that we will deposit with a depositary or with a nominee for a depositary identified in the applicable prospectus supplement and registered in the name of such depositary or nominee. In such case, we will issue one or more registered global securities denominated in an amount equal to the aggregate principal amount of all of the debt securities of the series to be issued and represented by such registered global security or securities.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a registered global security may not be transferred except as a whole:

The prospectus supplement relating to a series of debt securities will describe the specific terms of the depositary arrangement with respect to any portion of such series represented by a registered global security. We anticipate that the following provisions will apply to all depositary arrangements for debt securities:

24

The laws of some states may require that certain purchasers of securities take physical delivery of the securities in definitive form. These laws may limit the ability of those persons to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary for a registered global security, or its nominee, is the registered owner of the registered global security, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the indenture.

Except as set forth below, owners of beneficial interests in a registered global security:

Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for the registered global security and, if the person is not a participant, on the procedures of a participant through which the person owns its interest, to exercise any rights of a holder under the indenture.

We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take the action, and those participants would authorize beneficial owners owning through those participants to give or take the action or would otherwise act upon the instructions of beneficial owners holding through them.

We will make payments of principal and premium, if any, and interest, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee to the depositary or its nominee, as the case may be, as the registered owners of the registered global security. None of us, the trustee or any other agent of us or the trustee will be responsible or liable for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payments of principal and premium, if any, and interest, if any, in respect of the registered global security, will immediately credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the registered global security as shown on the records of the depositary. We also expect that standing customer instructions and customary practices will govern payments by participants to owners of beneficial interests in the registered global security held through the participants, as is now the case with the securities held for the accounts of customers in bearer form or registered in "street name." We also expect that any of these payments will be the responsibility of the participants.

If the depositary for any debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, we will appoint an eligible successor depositary. If we fail to appoint an eligible successor depositary, we will issue the debt securities in definitive form in exchange for the registered global security. In addition, we may at any time and in our sole discretion decide not to have any of the debt securities of a series represented by one or more registered global securities. In such event, we will issue debt securities of that series in a definitive form in exchange for all of the registered global securities representing the debt securities. The trustee will register any debt securities issued in definitive form in exchange for a registered global security in such name or names as the depositary, based upon instructions from its participants, instructed to the trustee.

25

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance

We may deposit with the trustee, in trust, cash or U.S. government securities in an amount that, through the payment of interest and principal in accordance with their terms, will provide, not later than one day before the due date of any payment of money, an amount in cash that is sufficient to make all payments of principal and interest on, and any mandatory sinking fund payments in respect of, the debt securities of that series on the due dates for such payments in accordance with the terms of the indenture and those debt securities. If we make such a deposit, unless otherwise provided under the applicable series of debt securities, we will be discharged from any and all obligations in respect of the debt securities of such series (except for obligations relating to the transfer or exchange of debt securities and the replacement of stolen, lost or mutilated debt securities and relating to maintaining paying agencies and the treatment of funds held by paying agents and certain rights of the trustee and our obligations with respect thereto). However, this discharge may occur only if, among other things, we have delivered to the trustee a legal opinion stating that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and, based thereon confirming that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance had not occurred.

Defeasance of Certain Covenants

Under the indentures (and unless otherwise provided by the terms of the applicable series of debt securities), upon making the deposit and delivering the legal opinion described in "Legal Defeasance" above, we will not

need to comply with certain covenants set forth in the indentures, as well as any additional covenants that may be set forth in the applicable prospectus supplement, and any such noncompliance will not constitute a default or an event of default with respect to the debt securities of that series, or covenant defeasance.

Covenant Defeasance and Events of Default

If we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amounts on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. We will remain liable for those payments.

Satisfaction and Discharge

We may discharge our obligations under either indenture and the debt securities of a series (except for certain surviving rights of the trustee and our obligations in connection therewith) if: (a) all outstanding debt securities of that series and all other outstanding debt securities issued under such indenture (i) have been delivered for cancellation, or (ii) (1) have become due and payable, (2) will become due and payable at their stated maturity within one year or (3) are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice and redemption by the trustee (and in the case of clauses (1), (2) and (3), we have deposited with the trustee an amount sufficient to pay and discharge the principal of (and premium, if any), and interest on all outstanding debt securities and any other sums due on the stated maturity date or redemption date, as the case may be); (b) we have paid all other sums payable by us under such indenture; and (c) we have delivered an officers' certificate and opinion of counsel confirming compliance with all conditions precedent relating to the satisfaction and discharge of the indenture.

26

Amendments to the Indentures

Each indenture provides that we and the trustee may enter into supplemental indentures without the consent of the holders of debt securities:

27

Each indenture also provides that we and the trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series of Senior Debt Securities or Subordinated Debt Securities, as the case may be, then outstanding and affected thereby (voting as one class), add any provisions to, or change in any manner, eliminate in any way the provisions of, the indenture or supplemental indenture or modify in any manner the rights of the holders of the debt securities. We and the trustee may not, however, without the consent of the holder of each outstanding debt security affected thereby:

Concerning the Trustee

The indentures limit the right of the trustee, should it become a creditor of ours, to obtain payment of claims or secure its claims. The trustee is permitted to engage in certain other transactions. However, if the trustee acquires any conflicting interest, and there is a default under the debt securities of any series for which it is trustee, the trustee must eliminate the conflict or resign.

No Individual Liability of Directors, Officers, Employees or Stockholders

The indentures provide that none of our incorporators, directors, officers, employees, stockholders or agents will have any liability for any of our obligations under the debt securities or the indentures or for any claim based on, in respect of or by reason of such obligations or their creation. Each holder of debt securities by accepting a debt security waives and releases all such liability. The waiver and release will be part of the consideration for the issue of the debt securities.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

28

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including contracts obligating holders to purchase from, or to sell to, us, and obligating us to sell to, or to purchase from, the holders, a specified number of shares of our common stock, preferred stock or depositary shares at a future date or dates. The price per share of common stock, preferred stock or depositary shares and the number of shares of each may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts. The applicable prospectus supplement will describe the terms of the purchase contracts, including, if applicable, collateral or depositary arrangements.

29

DESCRIPTION OF UNITS

We may sell any combination of one or more of the other securities described in this prospectus, together as units. In a prospectus supplement, we will describe the particular combination of securities constituting any units and any other specific terms of the units.

USE OF PROCEEDS

We will retain broad discretion over the use of the net proceeds from the sale of the securities offered hereby. Unless otherwise specified in the applicable prospectus supplement, we expect to use the net proceeds of our sale of securities for general corporate purposes. General corporate purposes may include, among others, the following:

The precise amounts and the timing of our use of the net proceeds will depend upon market conditions, our bank subsidiary's funding requirements, the availability of other funds, and other factors. Pending such use for general corporate purposes, we may temporarily invest the net proceeds in short-term securities or reduce our short-term indebtedness, or we may hold the net proceeds in deposit accounts in our subsidiary bank. We expect that we will, on a recurrent basis, engage in additional financings as the need arises to finance our corporate strategies, to fund our subsidiaries, to finance acquisitions or otherwise.

The prospectus supplement with respect to an offering of any security may identify different or additional uses for the proceeds of that offering.

30

SELLING SECURITY HOLDERS

Selling security holders are persons or entities that, directly or indirectly, have acquired or will from time to time acquire from us, our securities in various private transactions. Such selling security holders may be parties to registration rights agreements with us, or we otherwise may have agreed or will agree to register their securities for resale. The initial purchasers of our securities, as well as their transferees, pledgees, donees or successors, all of whom we refer to as "selling security holders," may from time to time offer and sell the securities pursuant to this prospectus and any applicable prospectus supplement.

The applicable prospectus supplement will set forth the name of each selling security holder and the number of and type of securities beneficially owned by such selling security holder that are covered by such prospectus supplement. The applicable prospectus supplement also will disclose whether any of the selling security holders have held any position or office with, have been employed by or otherwise have had a material relationship with us during the three years prior to the date of the prospectus supplement.

31

PLAN OF DISTRIBUTION

We and/or any selling security holder may sell common stock, preferred stock, depositary shares, debt securities, purchase contracts or units in one or more of the following ways from time to time:

Any underwriters, dealers, or agents will be identified, and the purchase price of the securities, the proceeds to us from the sale, any underwriting discounts and commissions, agency fees, discounts or concessions allowed or reallowed to dealers, and other items constituting underwriters' or agents' compensation, any initial public offering price, and any securities exchanges on which the securities are listed, will be described in the applicable prospectus supplement or term sheet.

We (directly or through agents) or any selling security holder may sell, and the underwriters, dealers or agents may resell, the offered securities in one or more transactions, including negotiated transactions, through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate, at a fixed public offering price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. If underwriters are used in the sale, the underwriters will acquire the offered securities for their own account and may resell them from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. Unless otherwise set forth in a prospectus supplement, the obligations of the underwriters to purchase any series of offered securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all of such series of offered securities if any are purchased.

In connection with the sale of offered securities, the underwriters or agents may receive compensation from us or from purchasers of the offered securities for whom they may act as agents. The underwriters may sell offered securities to or through dealers, who may also receive compensation from purchasers of the offered securities for whom they may act as agents. Compensation may be in the form of discounts, concessions or commissions, including discounts or concessions allowed or reallowed or paid to dealers. If a dealer is used in the sale, we will sell such offered securities to the dealer, as principal. The dealer may then resell the offered securities to the public at varying prices to be determined by that dealer at the time for resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction. Offered securities may be sold directly by us to one or more institutional purchasers, or through agents designated by us from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Any agent involved in the offer or sale of the offered securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement relating to that offering. Unless otherwise indicated in such prospectus supplement, any such agent will be acting on a best-efforts basis for the period of its appointment. Underwriters, dealers and agents that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act and any discounts or commissions received by them from us and any profit on the resale of the offered securities by them may be treated as underwriting discounts and commissions under the Securities Act.

In connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise

32

affect the market price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids. A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security. A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering. A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions. These transactions may be effected on the Nasdaq Global Select Market or otherwise. Underwriters are not required to engage in any of these activities, or to continue such activities if commenced.

To the extent that we make sales to or through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will issue and sell shares of our common stock to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell shares on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement will provide that any shares of our common stock sold will be sold at prices related to the then prevailing market prices for our common stock. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus. If any underwriter or agent acts as principal, or broker-dealer acts as underwriter, it may engage in certain transactions that stabilize, maintain or otherwise affect the price of our securities. We will describe any such activities in the prospectus supplement relating to the transaction.

We may indemnify the underwriters and agents against certain civil liabilities, including liabilities under the Securities Act, or contribute to payments they may be required to make in respect of such liabilities. Underwriters, dealers and agents may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that the underwriters, dealers or agents may be required to make in respect thereof.

Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our affiliates in the ordinary course of their businesses. Other than our common stock, which is listed on the Nasdaq Global Select Market, each of the securities issued hereunder will be a new issue of securities, will have no prior trading market, and may or may not be listed on a national securities exchange. Any common stock sold pursuant to a prospectus supplement will be listed on the Nasdaq Global Select Market, subject to official notice of issuance. Any underwriters to whom we sell securities for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot assure you that there will be a market for the offered securities.

33
