[424B2] Marex Group plc Prospectus Supplement

Rhea-AI Filing Summary

Marex Group plc is offering leveraged barrier notes linked to the STOXX® Europe 600 Index. Each Note has a $1,000 principal amount, trades in book-entry form and is expected to mature on December 27, 2027, with the final index level observed on December 20, 2027. Application has been made to list the Notes on the Vienna MTF of the Vienna Stock Exchange.

At maturity, investors receive cash based on index performance. If the index return is positive, the payoff is $1,000 plus 151% of the positive return. If the index return is between 0% and the -15% barrier, investors receive only their $1,000 back. If the index return falls below the -15% barrier, the payoff is reduced one-for-one with the index loss, down to a possible total loss of principal. The Notes pay no periodic interest, are senior unsecured obligations of Marex and are subject to its credit risk. The Estimated Initial Value on the pricing date is expected to be between $940 and $980 per Note, lower than the price to the public.

GENERAL

This document relates to an offering of Notes linked to the Reference Asset. The purchaser of a Note will acquire a senior unsecured debt security of Marex. We reserve the right to withdraw, cancel or modify this offering and to reject orders in whole or in part. Although the offering of Notes relates to the Reference Asset, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any security included in the Reference Asset or as to the suitability of an investment in the Notes.

You should read this document together with the prospectus dated August 4, 2025 (the “prospectus”), the prospectus supplement dated August 4, 2025 (the “prospectus supplement”) and the Equity Index Underlying Supplement dated August 4, 2025 (the “underlying supplement”). If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus, prospectus supplement or underlying supplement, the terms described in this document shall control. You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-7 of this document, page S-1 of the prospectus supplement and page S-1 of the underlying supplement, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes. As used herein, references to the “Issuer”, “Marex”, “we”, “us” and “our” are to Marex Group plc. Certain terms used but not defined herein will have the meanings set forth in the underlying supplement, the prospectus supplement or the prospectus.

You may access the underlying supplement, the prospectus supplement and the prospectus on the SEC website www.sec.gov as follows (or if such address has changed, by reviewing our filing for the relevant date on the SEC website):

^▶  The underlying supplement at: https://www.sec.gov/Archives/edgar/data/1997464/000119312525172164/d92960d424b2.htm

We are using this document to solicit from you an offer to purchase the Notes. You may revoke your offer to purchase the Notes at any time prior to the time at which we accept your offer by notifying MCMI. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their issuance. In the event of any material changes to the terms of the Notes, we will notify you.

PS-4

PAYMENT ON THE NOTES

On the Maturity Date, for each $1,000 Principal Amount of the Notes, we will pay you the Payment at Maturity, which is an amount in cash, calculated as follows:

If the Reference Return is greater than zero:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

If the Reference Return is less than or equal to zero but greater than or equal to the Barrier Percentage:

$1,000 (zero return).

If the Reference Return is less than the Barrier Percentage:

$1,000 + ($1,000 × Reference Return).

In this case, you will lose 1% of the Principal Amount of your Notes for each percentage point that the Reference Return is below zero. For example, if the Reference Return is -50%, you will suffer a 50% loss and receive 50% of the Principal Amount, subject to the credit risk of Marex. If the Reference Return is less than the Barrier Percentage, you will lose more than 15%, and possibly all, of your investment.

Interest

The Notes will not pay interest.

PS-6

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-1 of the accompanying prospectus supplement and page S-1 of the accompanying underlying supplement. You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this document and the accompanying prospectus, prospectus supplement and underlying supplement. In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and underlying supplement including the explanation of risks relating to the Notes described in the following sections:

^▶  “—Risks Related to Note Issuances” in the prospectus supplement; and

^▶  “—General risks related to an Index” in the underlying supplement.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

Risks Relating to the Structure or Features of the Notes

You may lose some or all of the principal at maturity.

You will be exposed to any decrease in the Final Value from the Initial Value if the Reference Return is below the Barrier Percentage. Accordingly, if the Reference Return is less than the Barrier Percentage, your Payment at Maturity will be less than the Principal Amount of your Notes, and you will lose some or all of your investment at maturity.

The amount payable on the Notes is not linked to the value of the Reference Asset at any time other than on the Final Valuation Date.

The Final Value will be the Closing Level of the Reference Asset on the Final Valuation Date, subject to postponement for non-trading days and certain Market Disruption Events. Even if the value of the Reference Asset increases during the term of the Notes other than on the Final Valuation Date but then decreases on the Final Valuation Date to a value that is less than the Initial Value, the Payment at Maturity will be less, possibly significantly less, than it would have been had the Payment at Maturity been linked to the value of the Reference Asset prior to that decrease. Although the actual value of the Reference Asset on the Maturity Date or at other times during the term of the Notes may be higher than the Final Value, the Payment at Maturity will be based solely on the value of the Reference Asset on the Final Valuation Date.

The Notes will not bear interest.

As a holder of the Notes, you will not receive interest payments.

Risks Relating to the Reference Asset

Changes that affect the Reference Asset may affect the value of the Reference Asset and the return on the Notes.

The policies of the Reference Sponsor of the Reference Asset concerning additions, deletions and substitutions of the stocks included in the Reference Asset , and the manner in which the Reference Sponsor takes account of certain changes affecting those stocks, may adversely affect the value of the Reference Asset. The policies of the Reference Sponsor with respect to the calculation of the Reference Asset could also adversely affect the value of the Reference Asset. The Reference Sponsor may discontinue or suspend calculation or dissemination of the Reference Asset. Any such actions could adversely affect the value of the Reference Asset and the value of and the return on the Notes.

The Notes are subject to risks associated with non-U.S. companies.

The value of the Index depends upon the stocks of non-U.S. companies, and thus involves risks associated with the home countries of those non-U.S. companies. The prices of these non-U.S. stocks may be affected by political, economic, financial and social factors in the home country of each applicable company, including changes in that country’s government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could affect the value of the Notes. These foreign securities may have less liquidity and could be more volatile than many of the securities traded in U.S. or other securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the Index and, as a result, the value of the Notes.

The Notes will not be adjusted for changes in exchange rates.

Although the equity securities included in the Index are traded in currencies other than U.S. dollars, and your Notes are denominated in U.S. dollars, the amount payable on your Notes at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the currencies in which these non-U.S. equity securities are denominated. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the value of the Index and therefore your Notes. The amount we pay on your Notes at maturity, if any, will be determined solely in accordance with the procedures described in this document.

PS-7

General Risk Factors

The Notes are subject to our credit risk.

Marex may partially or wholly fail to meet their obligations under the Notes. Investors should therefore take the creditworthiness of Marex and its subsidiaries into account in their investment decision. Credit risk means the risk of insolvency or illiquidity of an issuer, i.e. a potential, temporary or final inability to fulfil their interest and repayment obligations on time. An increased insolvency risk is typical of issuers that have a low creditworthiness. The payment of any amount due on the Notes is subject to the credit risk of Marex. The Notes are senior unsecured debt obligations of Marex, and are not, either directly or indirectly, an obligation of any third party. Investors are dependent on Marex’s ability to pay all amounts due on the Notes, and therefore investors are subject to the credit risk of the Marex and to changes in the market’s view of its creditworthiness.

The Notes are not bank deposits and are not insured or guaranteed by the U.S. Federal Deposit Insurance Corporation, the UK Financial Services Compensation Scheme or any other government or governmental or private agency or deposit protection scheme in any jurisdiction. Investors are dependent on Marex’s ability to pay all amounts due on the Notes, and therefore investors are subject to Marex’s credit risk and to changes in the market’s view of the Marex’s creditworthiness. The payment of any amount due on the Notes is not guaranteed by any entity.

The Notes are not insured against loss by any third parties; you can depend only on our earnings and assets for any payment on the Notes.

The Notes will be solely our obligations, and no other entity will have any obligation, contingent or otherwise, to make any payments in respect of the Notes.

The Estimated Initial Value of the Notes, which will be determined by us on the Trade Date, is expected to be less than the price to public and may differ from the market value of the Notes in the secondary market, if any.

The Estimated Initial Value of the Notes will be calculated by us on the Trade Date and is expected to be less than the price to public. The Estimated Initial Value will reflect our and our affiliates’ internal funding rate, which is the borrowing rate paid to issue market-linked securities, as well as the mid-market value of the embedded derivatives in the Notes. This internal funding rate is typically lower than the rate we would use when we issue conventional fixed or floating rate debt securities. As a result of the difference between our internal funding rate and the rate we would use when we issue conventional fixed or floating rate debt securities, the Estimated Initial Value of the Notes may be lower if it were based on the prices at which our fixed or floating rate debt securities trade in the secondary market. In addition, if we were to use the rate we use for our conventional fixed or floating rate debt issuances, we would expect the economic terms of the Notes to be more favorable to you. We will determine the value of the embedded derivatives in the Notes by reference to our or our affiliates’ internal pricing models. These pricing models consider certain assumptions and variables, which can include volatility and interest rates. Different pricing models and assumptions could provide valuations for the Notes that are different from our Estimated Initial Value. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. The Estimated Initial Value does not represent a minimum price at which we or any of our affiliates would be willing to purchase your Notes in the secondary market (if any exists) at any time.

The price of your Notes in the secondary market, if any, immediately after the Trade Date is expected to be less than the price to public.

The price to public takes into account certain costs. These costs include our affiliates’ projected hedging profits (which may or may not be realized) for assuming risks inherent in hedging our obligations under the Notes, the underwriting discount and the costs associated with structuring and hedging our obligations under the Notes. These costs will be used or retained by us or one of our affiliates, except for underwriting discounts paid to unaffiliated distributors. If you were to sell your Notes in the secondary market, if any, the price you would receive for your Notes may be less than the price you paid for them because secondary market prices will not take into account these costs. The price of your Notes in the secondary market, if any, at any time after issuance will vary based on many factors, including the value of the Reference Asset and changes in market conditions, and cannot be predicted with accuracy. The Notes are not designed to be short-term trading instruments, and you should, therefore, be able and willing to hold the Notes to maturity. Any sale of the Notes prior to maturity could result in a loss to you.

If we were to repurchase your Notes immediately after the Original Issue Date, the price you receive may be higher than the Estimated Initial Value of the Notes.

Assuming that all relevant factors remain constant after the Original Issue Date, the price at which MCMI may initially buy or sell the Notes in the secondary market, if any, and the value that may initially be used for customer account statements, if any, may exceed the Estimated Initial Value on the Trade Date for a temporary period expected to be approximately 6 months after the Original Issue Date. This temporary price difference may exist because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes that we will no longer expect to incur over the term of the Notes. We will make such discretionary election and determine this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the Original Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

PS-8

You will not have any ownership interest in the stocks included in the Reference Asset.

As a holder of the Notes, you will not have any ownership interest in the stocks included in the Reference Asset , such as rights to vote, dividend payments or other distributions. Because the return on the Notes will not reflect any dividends on those stocks, the Notes may underperform an investment in the stocks included in the Reference Asset.

The Notes lack liquidity.

The Notes are a new issue of securities for which there is no established market. Although we will apply for the Notes to be listed for trading on the Vienna MTF, we cannot provide you with any assurance regarding whether the Notes will become or remain listed or whether a trading market for the Notes will develop or as to the liquidity or sustainability of any such market, the ability of holders of the Notes to sell their Notes or the price at which holders may be able to sell their Notes. The listing application will be subject to approval by the Vienna Stock Exchange. There can be no assurance that application for listing and admission to trading will be granted or than an active trading market in the Notes will develop. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the Notes at any time. In addition, MCMI is not required to offer to purchase the Notes in the secondary market. Even if a secondary market were to develop, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which MCMI is willing to buy the Notes.

Potential conflicts of interest may exist.

Marex and its affiliates play a variety of roles in connection with the issuance of the Notes, including acting as calculation agent and hedging our obligations under the Notes. Following the occurrence of certain events – relating to the Issuer, the Issuer’s hedging arrangements, the Reference Asset, taxation, the relevant currency or other matters – outside of the Issuer’s control, the calculation agent may determine in its discretion to take one of the actions available to it in order to deal with the impact of such event on the Notes or the Issuer or both. These actions may include (i) adjustment to the terms and conditions of the Notes, (ii) substitution of the Reference Asset and/or (iii) early redemption or exercise of the Notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Notes. Any such discretionary determination by the Issuer or the calculation agent could have a negative impact on the value of the Notes. We will not have any obligation to consider your interests as a holder of the Notes in taking any action that might adversely affect the value of your Notes.

Uncertain tax treatment.

For a discussion of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “U.S. Federal Income Tax Considerations” herein, the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement and the discussion under “Material Tax Considerations — Material U.S. Federal Income Tax Considerations” in the accompanying prospectus.

ILLUSTRATIVE EXAMPLES

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the Final Value relative to the Initial Value. We cannot predict the Closing Level of the Reference Asset at any time during the term of the notes, including the Final Valuation Date. The assumptions we have made in connection with the illustrations set forth below may not reflect actual events. You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset or the return on your Notes. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table and examples below illustrate the Payment at Maturity on a $1,000 investment in the Notes for a hypothetical range of Reference Returns from -100% to +100%. The following results are based solely on the assumptions outlined below. The “Hypothetical Return on the Notes” as used below is the number, expressed as a percentage, that results from comparing the Payment at Maturity per $1,000 Principal Amount to $1,000. The potential returns described below assume that the Notes are held to maturity. The following table and examples assume the following:

Principal Amount:		$1,000
Hypothetical Initial Value:		100.00
Upside Participation Rate:		151.00%
Barrier Percentage:		-15.00%

Hypothetical Final Value		Hypothetical Reference Return		Hypothetical Payment at Maturity		Hypothetical Return on the Notes
200.00		100.00%		$2,510.00		151.00%
175.00		75.00%		$2,132.50		113.25%
150.00		50.00%		$1,755.00		75.50%
125.00		25.00%		$1,377.50		37.75%
110.00		10.00%		$1,151.00		15.10%
100.00(1)		0.00%		$1,000.00		0.00%
95.00		-5.00%		$1,000.00		0.00%
90.00		-10.00%		$1,000.00		0.00%
85.00		-15.00%(2)		$1,000.00		0.00%
84.00		-16.00%		$840.00		-16.00%
80.00		-20.00%		$800.00		-20.00%
75.00		-25.00%		$750.00		-25.00%
50.00		-50.00%		$500.00		-50.00%
25.00		-75.00%		$250.00		-75.00%
0.00		-100.00%		$0.00		-100.00%

(1) The hypothetical Initial Value of 100 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Initial Value of the Reference Asset.

(2) This is the Barrier Percentage.

PS-10

The following examples indicate how the Payment at Maturity would be calculated with respect to a hypothetical $1,000 investment in the Notes assuming that the Notes are held to maturity.

Example 1: The Reference Return Is 10.00%.

Because the Reference Return is greater than zero, the Payment at Maturity would be $1,151.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return × Upside Participation Rate)

= $1,000 + ($1,000 × 10.00% ×151.00%)

= $1,151.00

Example 1 shows that the Notes provide a leveraged return if the Reference Return is positive.

Example 2: The Reference Return Is -5.00%.

Because the Reference Return is less than or equal to zero but greater than or equal to the Barrier Percentage, the Payment at Maturity would be $1,000.00 per $1,000 Principal Amount (a zero return).

Example 2 shows that the Payment at Maturity will equal the Principal Amount if the Reference Return is less than or equal to zero but greater than or equal to the Barrier Percentage, although the value of the Reference Asset has decreased moderately.

Example 3: The Reference Return Is -75.00%.

Because the Reference Return is less than the Barrier Percentage, the Payment at Maturity would be $250.00 per $1,000 Principal Amount, calculated as follows:

$1,000 + ($1,000 × Reference Return)

= $1,000 + ($1,000 × -75.00%)

= $250.00

Example 3 shows that you are exposed on a 1-to-1 basis to any decrease in the value of the Reference Asset if the Reference Return is less than the Barrier Percentage. You may lose up to 100% of your Principal Amount at maturity.

DESCRIPTION OF THE REFERENCE ASSET

General

The Index is a free float capitalization-weighted index of 600 stocks. The Index is designed to provide a broad yet investable representation of the largest (by free float market capitalization) companies of 17 European countries and contains a fixed number of 600 components with a weighting cap of 20%. The Index was created by STOXX Limited (“STOXX” or the “Reference Sponsor”). The Index is reported daily on the Bloomberg Professional^® service (“Bloomberg”) under the symbol “SX5E” and on the STOXX website. We are not incorporating by reference the STOXX website or any material it includes in this pricing supplement. STOXX is under no obligation to continue to publish the Index and may discontinue publication of the Index at any time.

Component Selection

The composition of the Index is reviewed by STOXX quarterly and changes are typically implemented on the third Friday of every March, June, September and December, with effect on the next trading day. If the third Friday of the relevant month is not a trading day, then the implementation occurs on the next trading day, with effect on the following trading day. In connection with the quarterly review, the eligible stocks in the STOXX^® Europe Total Market Index are ranked in terms of free float market capitalization to produce the selection list for the Index. The STOXX^® Europe Total Market Index consists of the top 95% (subject to applicable buffer rules) by free-float market capitalization of the total equity having a country assignment in one of the 17 countries listed above (based on the country of incorporation, the primary listing and the country with the largest trading volume).

The selection list for the Index is updated and published on a monthly basis according to the review component selection process in case a replacement is needed for a deletion. To create the selection list for the Index, for each company having more than one eligible class of stock, only the most liquid class is eligible, and a liquidity screen of a 3-month average daily trading volume of greater than one million Euros is applied to the eligible stocks. The eligible stocks remaining after application of the liquidity screen are ranked by their free float market capitalizations.

At the quarterly review, the largest 550 stocks on the selection list qualify for selection for the Index. The remaining 50 stocks for the Index are selected from the current components ranked between 551 and 750 that meet all of the criteria (including the liquidity screen). If the number of stocks selected is still below 600, the largest (by free float market capitalization) stocks on the selection list are selected until there are 600 stocks.

Index Maintenance

The component stocks of the Index are monitored on an ongoing monthly basis for deletion and quarterly basis for addition. Changes to the composition of the Index due to corporate actions (including mergers and takeovers, spin-offs, sector changes and bankruptcy) are announced immediately, implemented two trading days later and become effective on the next trading day after implementation.

Any component stocks that are not traded for 10 consecutive days, are suspended from trading for 10 consecutive days or more and have not announced a resumption trading date, are officially delisted or are the subject of ongoing bankruptcy proceeds will be deleted from the Index. A deleted stock is replaced by the highest-ranked non-component on the selection list in the STOXX Europe Total Market Index to maintain the fixed number of stocks in the Index.

In the case of a spin-off, if the original stock was a component stock, then each spin-off stock qualifies for addition to the Index if it is equal to or above 550 on the latest selection list. The largest qualifying spin-off stock replaces the original component stock, while the next qualifying spin-off stock replaces the lowest ranked component stock and likewise for other qualifying spin-off stocks. Additions and deletions in connection with a quarterly review are announced on the first trading day of the review implementation month.

The free float factors and outstanding number of shares for each index stock that STOXX uses to calculate the Index, as described below, are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review. These changes are announced five trading days before they are implemented. Certain extraordinary adjustments to the factors and/or the number of outstanding shares are implemented and made effective more quickly. The timing depends on the magnitude of the change. The free float factor reduces the index stock’s number of shares to the actual amount available on the market. All holdings that are larger than five percent of the total outstanding number of shares and held on a long-term basis are excluded from the Index calculation (including, but not limited to, stock owned by the company itself, stock owned by governments, stock owned by certain individuals or families, and restricted shares). In addition, the weight of each component in the Index is capped at 20% of the Index’s total free float market capitalization.

Index Calculation

STOXX calculates the Index using the “Laspeyres formula,” which measures the aggregate price changes in the index stocks against a fixed base quantity weight. The discussion below describes the “price return” calculation of the Index. The formula for calculating the Index value can be expressed as follows:

Index level = free float market capitalization of the Index / divisor

The “free float market capitalization of the Index” is equal to the sum of the product of the price, the number of shares, the free float factor and the weighting cap factor for each index stock as of the time the Index is being calculated. Where any index component stock price is unavailable on any trading day, the index sponsor will generally use the last reported price for such component stock. If an index stock trades in a currency other than Euros, its stock price is converted into Euros using the midpoint between the latest real-time bid and ask prices for that currency. The closing index level is calculated by converting non-Euro stock prices to Euros using fixed foreign exchange rates (WM fixed exchange rates).

PS-12

In case the investability and tradability of the Index and index based products is affected by an upcoming market or company event that is considered significant or “extreme” by the STOXX Management Board, the following actions or a combination of the following actions are taken. For all such changes a minimum notification period of two full trading days will be observed. The action scope may include but is not limited to:

• application of expert judgment for index component pricing data,

• adjustment of operational procedures,

• postponement of index adjustments,

• adjustment of selection lists,

• change of weights of index constituents by adjusting the number of shares, free-float factors or weighting cap-factors, or

• adjustment of index compositions.

Index Divisor

The Index is calculated using a divisor that helps to maintain the continuity of the Index’s value so that corporate actions do not artificially increase or decrease the level of the Index. The divisor is calculated by starting with the previous divisor in effect for the Index (which we call the “original divisor value”) and multiplying it by a fraction, the numerator of which is the previous free float market capitalization of the Index, plus or minus the difference between the closing market capitalization of the Index and the adjusted closing market capitalization of the Index, and the denominator of which is the previous free float market capitalization of the Index. The adjusted free float market capitalization is calculated for stocks of companies that have experienced a corporate action of the type described below as of the time the new divisor value is being calculated using the free float market capitalization calculated with adjusted closing prices, the new number of shares, and the new free float factor minus the free float market capitalization calculated with that stock’s original closing price, number of shares, and free float factor, in each case as used in calculating the original divisor value. Errors in divisor calculation are corrected on an intraday basis if discovered on the same day the new divisor is effective. If the error is discovered later, the error is corrected on an intraday basis if feasible and only if the error is considered significant by the STOXX Management Board.

STOXX adjusts the divisor for the Index to maintain the continuity of the index values across changes due to certain corporate actions. Changes in weights due to corporate actions are distributed proportionally across all Index components and equal an investment into the portfolio.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed MCMI, an affiliate of Marex, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, MCMI will purchase the Notes from Marex at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this document relates, for distribution to other registered broker-dealers or will offer the Notes directly to investors. MCMI proposes to offer the Notes at the price to public set forth on the cover page of this document. MCMI will use the underwriting discount to pay selling concessions or fees (including custodial or clearing fees) to other registered broker-dealers.

An affiliate of Marex has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the Notes. We or one of our affiliates may pay a fee to one or more broker dealers for providing certain services with respect to this offering, which may reduce the economic terms of the Notes to you.

In addition, MCMI or another of our affiliates or agents may use the pricing supplement to which this document relates in market-making transactions after the initial sale of the Notes, but is under no obligation to make a market in the Notes and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-61 in the prospectus supplement.

We expect that delivery of the Notes will be made against payment for the Notes on or about the Original Issue Date set forth on the inside cover page of this document, which is more than one business day following the Trade Date. Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than one business day prior to the Original Issue Date will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The U.S. federal income tax consequences of each holder’s investment in the Notes are uncertain. There are no Treasury Regulations, published rulings or judicial decisions addressing the treatment for U.S. federal income tax purposes of securities with terms that are substantially the same as the Notes. By purchasing the Notes, each holder agrees (in the absence of a change in law, an administrative determination or a judicial ruling to the contrary) to treat each Note as a pre-paid executory contract for U.S. federal income tax purposes. In the opinion of our counsel, Mayer Brown LLP, it would generally be reasonable to treat the Notes as pre-paid executory contracts in respect of the Reference Asset for U.S. federal income tax purposes.

In addition, a U.S. Holder should generally recognize capital gain or loss upon redemption, sale or maturity or other taxable disposition of such holder’s Notes in an amount equal to the difference between the amount realized at such time and such holder’s tax basis in such Notes. In general, a U.S. Holder’s tax basis in the Notes will equal the holder’s cost for the Notes. Such gain or loss should generally be long-term capital gain or loss if a U.S. Holder has held the Notes for more than one year (otherwise such gain or loss should be short-term capital gain or loss if held for one year or less). The deductibility of capital losses is subject to limitations. U.S. Holders should consult their tax advisors regarding this risk.

The U.S. federal income tax consequences of a U.S. Holder’s investment in the Notes are uncertain and the Internal Revenue Service could assert that the Notes should be taxed in a manner that is different from that described above. Please see the discussion in the accompanying prospectus supplement under “U.S. Federal Income Tax Considerations” and in particular the discussion under “U.S. Federal Income Tax Considerations —U.S. Holders — Certain Notes Treated as a Put Option and a Deposit or an Executory Contract — Certain Notes Treated as Executory Contracts” and the discussion in the accompanying prospectus under “Material Tax Considerations — Material U.S. Federal Income Tax Considerations”. Non-U.S. Holders should review the discussion in the accompanying prospectus supplement under “U.S. Federal Income Tax Considerations — Non-U.S. Holders” for a discussion of the U.S. federal income tax consequences applicable to Non-U.S. Holders.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury Regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027. We expect that the delta of the Notes will not be one, and therefore, we expect that Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Reference Asset or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or an applicable withholding agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

PROSPECTIVE PURCHASERS OF THE NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE TAX CONSEQUENCES OF THE ABOVE DESCRIBED CHARACTERIZATION OF THE NOTES AND ANY POSSIBLE ALTERNATIVE CHARACTERIZATIONS OF THE NOTES FOR U.S. FEDERAL INCOME TAX PURPOSES. PROSPECTIVE PURCHASERS OF NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.
