**About This Prospectus Supplement**

This document consists of two parts. The first part is this prospectus supplement, which describes the common stock that the selling stockholders may offer and sell and supplements information contained in the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus. To the extent required by applicable law, each time the selling stockholders sell shares of common stock under this prospectus supplement, the selling stockholders will provide you with this prospectus supplement. The second part is the accompanying prospectus, which describes more general information, some of which may not apply to this offering. You should read both this prospectus supplement and the accompanying prospectus, including the documents incorporated by reference.

If the description of the offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement.

Any statement made in this prospectus supplement, the accompanying prospectus or in a document incorporated or deemed to be incorporated by reference in this prospectus supplement will be deemed to be modified or superseded for purposes of this prospectus supplement to the extent that a statement contained in this prospectus supplement or in any other subsequently filed document that is also incorporated or deemed to be incorporated by reference in this prospectus supplement modifies or supersedes that statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus supplement. See "Where You Can Find More Information; Incorporation of Certain Documents by Reference" in this prospectus supplement.

Neither the Company nor the selling stockholders have authorized anyone to provide you with any information or to make any representations about anything not contained or incorporated by reference in this prospectus supplement, any accompanying prospectus or in any free writing prospectus filed by us with the U.S. Securities and Exchange Commission ("SEC"). We do not take any responsibility for, and can provide no assurance as to the reliability of, any other information or representations that others may give you.

Neither the Company nor the selling stockholders are making an offer to sell or soliciting offers to buy these securities in any jurisdiction where, or to any person to whom, the offer or sale is not permitted.

Our business, financial condition, results of operations and future growth prospects may have changed since those dates.

On April 13, 2025, the Company and certain of its affiliate entities entered into a definitive agreement with RJO and certain affiliated entities and equity holders thereof, including affiliates of the selling stockholders, to acquire RJO (as amended, the "RJO Merger Agreement"). A portion of the consideration for the RJO Acquisition consisted of shares in the form of common stock issued by the Company to the selling stockholders. Pursuant to the RJO Merger Agreement, we agreed to register with the SEC the resale of all the shares of common stock issued to the selling stockholders in connection with the RJO Acquisition.

For investors outside the United States ("U.S."): neither the Company nor the selling stockholders have done anything that would permit this offering or possession or distribution of this prospectus supplement, the accompanying prospectus or any free writing prospectus we may provide to you in connection with this offering in any jurisdiction where action for that purpose is required, other than in the U.S. You are required to inform yourselves about and to observe any restrictions relating to this offering and the distribution of this prospectus supplement, the accompanying prospectus and any such free writing prospectus outside of the U.S.

These forward-looking statements involve known and unknown risks and uncertainties, many of which are beyond the control of the Company, including statements about the benefits of the RJO acquisition, including expected synergies and future financial and operating results, the plans, objectives, expectations and intentions of StoneX after the acquisition, adverse changes in economic, political and market conditions, including losses from our market-making and trading activities arising from counterparty failures, global trade policies and tariffs, the loss of key personnel, the impact of increasing competition, the impact of changes in government regulation, uncertainty concerning fiscal or monetary policies established by central banks and financial regulators, the possibility of liabilities arising from violations of foreign, U.S. federal and U.S. state securities laws, the impact of changes in technology in the securities and commodities trading industries, and other risks discussed in our filings with the SEC, including in our Annual Report.

The number of shares of common stock to be outstanding after this offering is based on 52,173,843 shares of common stock (including 3,085,554 shares of common stock that may be sold from time to time by the selling stockholders in this offering) outstanding as of August 25, 2025, and except as otherwise indicated, the number of shares of our common stock outstanding after this offering excludes 7,433,945 shares of our common stock issuable under the 2022 Omnibus Equity Incentive Plan (the "Omnibus Plan").

**Risk Factors**

Investing in our common stock involves risks. You should carefully review the risk factors and other cautionary statements described under the section entitled "Risk Factors" in our Annual Report which is incorporated by reference in this prospectus supplement, or any similar caption in the documents that we subsequently file with the SEC that are deemed to be incorporated by reference in this prospectus supplement, and in any free writing prospectus that we provide you in connection with the offering of common stock pursuant to this prospectus supplement. The risks and uncertainties discussed in the documents referred to above, as well as other matters discussed in this prospectus supplement and in those documents, could materially and adversely affect our business, financial condition, liquidity and results of operations and the market price of the common stock. Moreover, the risks and uncertainties discussed in the foregoing documents are not the only risks and uncertainties that we face, and our business, financial condition, liquidity and results of operations and the market price of the common stock could be materially adversely affected by other matters that are not known to us or that we currently do not consider to be material risks to our business.

**Use of Proceeds**

The selling stockholders will receive all of the net proceeds from the sale of the shares of common stock offered from time to time under this prospectus supplement. We will not receive any proceeds from the sale of shares of common stock by the selling stockholders. We have agreed to pay certain expenses incurred in connection with the registration of the resale of shares of common stock under this prospectus supplement. See "Selling Stockholders" and "Plan of Distribution."

**Selling Stockholders**

This prospectus supplement relates to the resale by the selling stockholders from time to time of up to 3,085,554 shares of common stock that the selling stockholders received in the form of common stock as partial consideration for the RJO Acquisition. The selling stockholders may from time to time offer and sell any or all of the shares of common stock set forth below pursuant to this prospectus supplement or any further supplements.

Pursuant to the RJO Merger Agreement, we agreed to register with the SEC the resale of all the shares of common stock issued to the selling stockholders in connection with the RJO Acquisition.

The following table shows information as of August 25, 2025 regarding the beneficial ownership of our common stock by the selling stockholders and sets forth the maximum number of shares of common stock eligible for resale by the selling stockholders under this prospectus supplement. The selling stockholders may in the future sell or transfer some or all of the securities indicated below in transactions exempt from the registration requirements of the Securities Act rather than under this prospectus supplement. The number of shares of common stock owned by the selling stockholders assumes that they do not beneficially own any shares of common stock other than the shares of common stock that the Company has issued to them in connection with the RJO Acquisition. We have prepared the following table based on information given to us by, or on behalf of, the selling stockholders. Information about the selling stockholders may change over time.

Beneficial ownership of shares is determined under the rules of the SEC and generally includes any shares over which a person exercises sole or shared voting or investment power. Except as noted by footnote, and subject to community property laws where applicable, we believe based on the information provided to us that the entities named in the table below have sole voting and investment power with respect to all shares of our common stock shown as beneficially owned by them.

**Material U.S. Federal Income and Estate Tax Considerations to Non-U.S. Holders**

The following is a general discussion of the material U.S. federal income and estate tax consequences of the ownership and disposition of our common stock by a "non-U.S. holder." A "non-U.S. holder" is a beneficial owner of a share of our common stock that is, for U.S. federal income tax purposes:

&nbsp;&nbsp;&nbsp;&nbsp;· a non-resident alien individual, other than a former citizen or resident of the United States subject to U.S. tax as an expatriate,

&nbsp;&nbsp;&nbsp;&nbsp;· a foreign corporation, or

&nbsp;&nbsp;&nbsp;&nbsp;· a foreign estate or trust.

If an entity or arrangement treated as a partnership or other type of pass-through entity for U.S. federal income tax purposes owns our common stock, the tax treatment of a partner or beneficial owner of the entity may depend upon the status of the partner or beneficial owner, the activities of the entity and certain determinations made at the partner or beneficial owner level. Partners and beneficial owners in partnerships or other pass-through entities that own our common stock should consult their own tax advisors as to the particular U.S. federal income and estate tax consequences applicable to them.

This discussion is based on the Internal Revenue Code of 1986, as amended to the date hereof (the "Code"), administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein (possibly with retroactive effect). This discussion does not address all aspects of U.S. federal income and estate taxation that may be relevant to non-U.S. holders in light of their particular circumstances and does not address any U.S. federal gift, alternative minimum tax or Medicare contribution tax considerations or any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction. Prospective holders are urged to consult their tax advisors with respect to the particular tax consequences to them of owning and disposing of our common stock, including the consequences under the laws of any state, local or non-U.S. jurisdiction.

**Dividends**

To the extent that we make a distribution of cash or other property (other than certain pro rata distributions of our stock) in respect of our common stock, the distribution generally will be treated as a dividend for U.S. federal income tax purposes to the extent it is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Any portion of a distribution that exceeds our current and accumulated earnings and profits generally will be treated first as a tax-free return of capital that reduces a non-U.S. holder's adjusted tax basis in our common stock, and to the extent the amount of the distribution exceeds a non-U.S. holder's adjusted tax basis in our common stock, the excess will be treated as gain from the disposition of our common stock (the tax treatment of which is discussed below under "—Gain on Disposition of Common Stock").

Dividends paid to a non-U.S. holder generally will be subject to U.S. federal withholding tax at a 30% rate, or a reduced rate specified by an applicable income tax treaty. In order to obtain a reduced rate of withholding under an applicable income tax treaty, a non-U.S. holder generally will be required to provide a properly executed Internal Revenue Service (the "IRS") Form W-8BEN or IRS Form W-8BEN-E, as applicable, certifying its entitlement to benefits under the treaty.

A non-U.S. holder eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

However, dividends paid to a non-U.S. holder that are effectively connected with the non-U.S. holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by the non-U.S. holder in the United States) will not be subject to U.S. federal withholding tax if the non-U.S. holder provides a properly executed IRS Form W-8ECI. Instead, the effectively connected dividend income will generally be subject to regular U.S. income tax as if the non-U.S. holder were a U.S. person as defined under the Code. A non-U.S. holder that is treated as a corporation for U.S. federal income tax purposes receiving effectively connected dividend income may also be subject to an additional "branch profits tax" imposed at a rate of 30% (or a lower treaty rate) on its effectively connected earnings and profits (subject to certain adjustments).

**Gain on Disposition of Common Stock**

Subject to the discussions of backup withholding and FATCA withholding taxes below, a non-U.S. holder generally will not be subject to U.S. federal income tax on gain realized on a sale or other disposition of common stock unless:

&nbsp;&nbsp;&nbsp;&nbsp;· the gain is effectively connected with a trade or business
of the non-U.S. holder in the United States (and, if required by an applicable tax treaty, the gain is attributable to a permanent establishment
or fixed base maintained by the non-U.S. holder in the United States), in which case the gain will be subject to U.S. federal income
tax generally in the same manner as if the non-U.S. holder were a U.S. person as defined under the Code (and, in the case of a non-U.S.
holder that is treated as a corporation for U.S. federal income tax purposes, may also be subject to the "branch profits tax"
described above);

&nbsp;&nbsp;&nbsp;&nbsp;· the non-U.S. holder is an individual present in the United
States for 183 days or more in the taxable year of disposition and certain other conditions are met, in which case the gain (net of certain
U.S.-source losses) generally will be subject to U.S. federal income tax at a rate of 30% (or a lower treaty rate); or

&nbsp;&nbsp;&nbsp;&nbsp;· we are or have been a "United States real property
holding corporation" (as described below) at any time within the five-year period preceding the disposition or the non-U.S. holder's
holding period, whichever period is shorter, and either (i) our common stock is not regularly traded on an established securities market
prior to the beginning of the calendar year in which the sale or disposition occurs or (ii) the non-U.S. holder has owned or is deemed
to have owned, at any time within the five-year period preceding the disposition or the non-U.S. holder's holding period, whichever period
is shorter, more than 5% of our common stock.

We will be a United States real property holding corporation at any time that the fair market value of our "United States real property interests," as defined in the Code and applicable Treasury regulations, equals or exceeds 50% of the aggregate fair market value of our worldwide real property interests and our other assets used or held for use in a trade or business (all as determined for U.S. federal income tax purposes). We believe that we are not, and do not anticipate becoming in the foreseeable future, a United States real property holding corporation.

**Information Reporting and Backup Withholding**

Distributions paid to a non-U.S. holder and the amount of any tax withheld with respect to such distributions generally will be reported to the IRS. Copies of the information returns reporting such distributions and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will not be subject to backup withholding on dividends received if such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a U.S. person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition of our common stock made within the U.S. or conducted through certain U.S.-related financial intermediaries, unless the non-U.S. holder complies with certification procedures to establish that it is not a U.S. person in order to avoid additional information reporting and backup withholding. The certification procedures required to claim a reduced rate of withholding under a treaty will generally satisfy the certification requirements necessary to avoid backup withholding as well.

Backup withholding is not an additional tax and the amount of any backup withholding from a payment to a non-U.S. holder will be allowed as a credit against the non-U.S. holder's U.S. federal income tax liability and may entitle the non-U.S. holder to a refund, provided that the required information is furnished to the IRS in a timely manner.

**FATCA** 

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as "FATCA"), payments of dividends on and the gross proceeds of dispositions of common stock of a U.S. issuer paid to (i) a "foreign financial institution" (as specifically defined in the Code) or (ii) a "non-financial foreign entity" (as specifically defined in the Code) will be subject to a withholding tax (separate and apart from, but without duplication of, the withholding tax described above) at a rate of 30%, unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied or an exemption from these rules applies. Under proposed U.S. Treasury regulations promulgated by the Treasury Department on December 13, 2018, which state that taxpayers may rely on the proposed Treasury regulations until final Treasury regulations are issued, this withholding tax will not apply to the gross proceeds from the sale or disposition of common stock. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under "—Dividends," the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Non-U.S. holders should consult their tax advisors regarding the possible implications of this withholding tax on their investment in our common stock.

**Federal Estate Tax**

Individual non-U.S. holders (as specifically defined for U.S. federal estate tax purposes) and entities the property of which is potentially includible in such an individual's gross estate for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers) should note that the common stock will be treated as U.S. situs property subject to U.S. federal estate tax, unless an applicable estate tax treaty provides otherwise.

**Plan of Distribution**

This prospectus supplement relates to the offer and sale from time to time of the shares of common stock covered by this prospectus supplement. The shares of common stock received by the selling stockholders as partial consideration pursuant to the RJO Merger Agreement are "restricted securities" within the meaning of Rule 144(a)(3) under the Securities Act and will contain a legend setting out such restriction and will be segregated until such time as they are sold under the registration statement of which this prospectus supplement forms a part. The Company is registering the resale of the shares of common stock to provide the holders thereof with freely tradeable securities, but such shares of common stock will not become freely tradeable until sold pursuant to the registration statement of which this prospectus supplement forms a part. There can be no assurance that the selling stockholders will sell any or all of the shares of common stock registered pursuant to the registration statement of which this prospectus supplement forms a part.

The selling stockholders may, from time to time, sell any or all of the shares of common stock offered hereby directly or indirectly through one or more broker-dealers or agents. The selling stockholders will be responsible for any agent's commissions. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. The selling stockholders may use any one or more of the following methods when selling shares of common stock:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· on NASDAQ or any other national securities exchange or quotation service on which the securities may be listed or quoted at the time
of sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the over-the-counter market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through the writing of options, swaps or derivatives whether such options are listed on an options exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through block trades in which the broker-dealer will attempt to sell the shares of common stock as agent but may position and resell
a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through purchases by a broker-dealer as principal and resale by such broker-dealer for its account;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through an exchange or market distribution in accordance with the rules of the applicable exchange or market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in privately negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through broker-dealers that may agree with the selling stockholders to sell a specified number of such shares of common stock at a
stipulated price per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· through a combination of any such methods of sale; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares of common stock under Rule 144 under the Securities Act, if available, rather than under this prospectus supplement.

The selling stockholders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. If the selling stockholders effect such transactions through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal, or both (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be less than or in excess of those customary in the types of transactions involved).

Pursuant to the RJO Merger Agreement, the Company has agreed to bear certain other costs, fees and expenses incurred in connection with the offering of common stock pursuant to this prospectus supplement. However, the Company does not have any obligation to pay any underwriting fees, discounts or commissions attributable to the sale of such shares of common stock, or any fees and expenses of any broker-dealer or other financial intermediary engaged by the selling stockholders.

**Legal Matters**

Davis Polk & Wardwell LLP, New York, New York, will pass upon the validity of the common stock offered by this prospectus supplement.

**THE COMPANY**

We operate a global financial services network that connects companies, organizations, traders and investors to the global market ecosystem through a unique blend of digital platforms, end-to-end clearing and execution services, high touch service and deep expertise. We strive to be the one trusted partner to our clients, providing our network, product and services to allow them to pursue trading opportunities, manage their market risks, make investments and improve their business performance. Our businesses are supported by our global infrastructure of regulated operating subsidiaries, our advanced technology platforms and our team of more than 4,600 employees as of December 31, 2024. We believe our client-first approach differentiates us from large banking institutions, engenders trust and has enabled us to establish market leading positions in a number of complex fields in financial markets around the world.

&nbsp;&nbsp;&nbsp;&nbsp;We offer a vertically integrated product suite, beginning with high-touch and electronic access to nearly all major financial markets worldwide, as well as numerous liquidity venues. We deliver this access through the entire lifecycle of a trade, from deep market expertise and on-the-ground intelligence to best execution and finally post-trade clearing, custody and settlement services. We believe this is a unique product offering outside of the bulge bracket banks, which creates long-term relationships with our clients. Our business model has created a revenue stream that is diversified by asset class, client type and geography, earning commissions and spreads as clients execute transactions across our global network, monetizing non-trading client activity including interest and fee earnings on client balances as well as earning consulting and fees for our market intelligence and risk management services.

We currently serve more than 54,000 commercial, institutional, and payments clients, and over 400,000 self-directed/retail accounts located in more than 180 countries. Our clients include commercial entities, regional, national and introducing broker-dealers, asset managers, insurance companies, brokers, institutional and individual investors, professional traders, commercial and investment banks as well as government and non-governmental organizations. We believe our clients value us for our attention to their needs, our expertise and flexibility, our global reach, our ability to provide access to liquidity in hard-to-reach markets and opportunities, and our status as a well-capitalized and regulatory-compliant organization.

We engage in direct sales efforts to seek new clients, with a strategy of extending our services to potential clients that are similar in size and operations to our existing client base. In executing this strategy, we intend to both target new geographic locations and expand the services offered in geographic locations in which we currently operate in an effort to increase our market share or where there is an unmet demand for our services. Through our mobile platforms and intranet websites, including StoneX.com, FOREX.com, and StoneXBullion.com we seek to attract and onboard new clients generated from digital marketing and brand advertising initiatives. We also pursue new clients through indirect channels, including our StoneX Marketing Partners affiliate program, StoneX.com/marketing partnerships; our relationships with introducing brokers, who solicit clients on our behalf; and white label partners, who offer our services to their clients under their own brand. In addition, we selectively pursue small- to medium-sized acquisitions, focusing primarily on targets that satisfy specified criteria, including client-centric organizations that enable us to increase market share in existing products, or which help us expand into new asset classes, client segments and geographies where we currently have a small or limited market presence.

&nbsp;&nbsp;&nbsp;&nbsp;We focus on mitigating exposure to market risk, ensuring adequate liquidity to maintain our daily operations and making non-interest expenses variable, to the greatest extent possible. Our strategy is to utilize a centralized and disciplined process for capital allocation, risk management and cost control, while delegating the execution of strategic objectives and day-to-day management to experienced individuals. This requires high quality managers, a clear communication of performance objectives and strong financial, operational and compliance controls. We believe this strategy will enable us to build a more scalable and significantly larger organization that embraces an entrepreneurial approach to business, supported and underpinned by strong centralized financial and compliance controls.

&nbsp;&nbsp;&nbsp;&nbsp;Our executive offices are located at 230 Park Ave, 10th Floor, New York, NY 10169. Our primary telephone number is (212) 485-3500 and our Internet address is <u>www.stonex.com</u>. Information on our website is not incorporated into this prospectus and is not a part of this prospectus.

**DESCRIPTION OF DEBT SECURITIES**

Please note that in this section entitled "Description of Debt Securities," references to the "Company," "we," "us," "ours" or "our" refer only to StoneX Group Inc. and not to its consolidated subsidiaries. Also, in this section, references to holders mean those who own debt securities registered in their own names, on the books that the Company or the trustee maintains for this purpose, and not those who own beneficial interests in debt securities registered in street name or in debt securities issued in book-entry form through one or more depositaries. Owners of beneficial interests in the debt securities should read the section below entitled "Form, Exchange and Transfer—Book-Entry Procedures and Settlement."

**General**

The following description sets forth general terms and provisions of the debt securities that we may issue, which may include convertible or exchangeable debt securities. We will set forth the particular terms of the debt securities we offer in a prospectus supplement. The extent, if any, to which the following general provisions apply to particular debt securities will be described in the applicable prospectus supplement. The following description of general terms relating to the debt securities and the indenture under which the debt securities will be issued are summaries only and therefore are not complete. You should read the indenture and the prospectus supplement regarding any particular issuance of debt securities.

The debt securities will represent our unsecured general obligations, unless otherwise provided in the prospectus supplement. We currently conduct all of our operations through our subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the debt securities or to make any funds available therefor, whether by dividends, loans or other payments. The holders of debt securities (whether senior or subordinated debt securities) will be effectively subordinated to the creditors of our subsidiaries. This means that creditors of our subsidiaries will have a claim to the assets of our subsidiaries that is superior to the claim of our creditors, including holders of our debt securities.

The debt securities will be issued under an indenture to be entered into between us and The Bank of New York Mellon, as trustee, which we refer to as the "trustee." The indenture, and any supplemental indentures thereto, will be subject to, and governed by, the Trust Indenture Act of 1939, as amended.

The form of indenture gives us broad authority to set the particular terms of each series of debt securities issued thereunder, including, without limitation, the right to modify certain of the terms contained in the indenture.

Except to the extent set forth in a prospectus supplement, the indenture does not contain any covenants or restrictions that afford holders of the debt securities special protection in the event of a change of control or highly leveraged transaction.

The indenture will not limit the aggregate principal amount of debt securities that may be issued under it and provides that debt securities may be issued in one or more series, in such form or forms, with such terms and up to the aggregate principal amount that we may authorize from time to time. We will establish the terms of each series of debt securities, and such terms will be set forth or determined in the manner provided in one or more resolutions of the board of directors or by a supplemental indenture. The particular terms of the debt securities offered pursuant to any prospectus supplement will be described in the prospectus supplement. All debt securities of one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of any holder, for issuances of additional debt securities of that series.

**Information in the Prospectus Supplement**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate principal amount of the debt securities and any limit upon the aggregate principal amount of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where the principal and premium, if any, make-whole amount, if any, and interest on the debt securities, if any, shall be payable, where the holders may surrender debt securities for conversion, transfer or exchange and where notices or demands to or upon us may be served;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions relating to the issuance of the debt securities at an original issue discount;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price or prices at which, the period or periods within which and the terms and conditions upon which we may redeem the debt securities, in whole or in part, pursuant to any sinking fund or otherwise (including, without limitation, the form or method of payment if other than in cash);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our obligation, if any, to redeem, purchase or repay the debt securities pursuant to any mandatory redemption, sinking fund or analogous provisions or at the option of a holder, the price at which, the period within which and the terms and conditions upon which the debt securities shall be redeemed, purchased or repaid, in whole or in part, pursuant to such obligation (including, without limitation, the form or method of payment thereof if other than in cash) and any provisions for the remarketing of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our obligation, if any, to permit the conversion or exchange of the debt securities of such series into shares of common stock or other capital stock or property, or combination thereof, and the terms and conditions upon which such conversion shall be effected (including, without limitation, the initial conversion or exchange price or rate, the conversion or exchange period, the provisions for conversion or exchange price or rate adjustments and any other provision relative to such obligation) and any limitations on the ownership or transferability of the securities or property into which holders may convert or exchange the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any trustees, authenticating or paying agents, transfer agents or registrars or any other agents with respect to the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency or currency units, including composite currencies, in which the debt securities shall be denominated if other than the currency of the United States of America;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the principal of, premium, if any, make-whole amount, if any, or interest on the debt securities is to be payable, at our election or the election of a holder, in currency or currency units other than that in which the debt securities are denominated or stated, the period within which, and the terms and conditions upon which such election may be made and the time and manner of and identity of the exchange rate agent with responsibility for determining the exchange rate between the currency or currency units in which the debt securities are denominated or stated to be payable and the currency or currency units in which the debt securities will be payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the amount of the payments of principal of, premium, if any, make-whole amount, if any, and interest on the debt securities may be determined with reference to an index, the manner in which the amount shall be determined from that index;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether and under what circumstances we will pay additional amounts on the debt securities held by foreign holders in respect of any tax, assessment or governmental charge withheld or deducted and, if so, whether we will have the option to redeem the debt securities rather than pay such additional amounts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if receipt of certain certificates or other documents or satisfaction of other conditions will be necessary for any purpose, including, without limitation, as a condition to the issuance of the debt securities in definitive form (whether upon original issue or upon exchange of a temporary debt security), the form and terms of such certificates, documents or conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other affirmative or negative covenants with respect to the debt securities;

Unless otherwise indicated in the prospectus supplement relating to the debt securities, the principal amount of and any premium or make-whole amount or interest on the debt securities will be payable, and the debt securities will be exchangeable and transfers thereof will be registrable, at the office of the trustee. However, at our option, payment of interest may be made by check mailed to the address of the person entitled thereto as it appears in the debt security register. Any payment of principal and any premium or make-whole amount or interest required to be made on an interest payment date, redemption date or at maturity that is not a business day need not be made on such date, but may be made on the next succeeding business day with the same force and effect as if made on the applicable date, and no interest shall accrue for the period from and after such date.

Unless otherwise indicated in the prospectus supplement relating to debt securities, the debt securities will be issued only in fully registered form, without coupons, in denominations of $1,000 or any integral multiple thereof. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge required to be paid in connection with a transfer or exchange.

------

Debt securities may bear interest at fixed or floating rates. We may issue our debt securities at an original issue discount, bearing no interest or bearing interest at a rate that, at the time of issuance, is below market rate, to be sold at a substantial discount below their stated principal amount. Generally speaking, if our debt securities are issued at an original issue discount and there is an acceleration of their maturity, holders will receive an amount less than the debt securities' principal amount. Tax and other special considerations applicable to any series of debt securities, including original issue discount debt, will be described in the prospectus supplement in which we offer those debt securities. In addition, certain United States federal income tax or other considerations, if any, applicable to any debt securities which are denominated in a currency or currency unit other than United States dollars may be described in the applicable prospectus supplement.

**Global Securities** 

The debt securities of a series may be issued in the form of one or more global securities that will be deposited with a depositary or its nominees identified in the prospectus supplement relating to the debt securities. In such a case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding debt securities of the series to be represented by such global security or securities.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a global security may not be registered for transfer or exchange except as a whole by the depositary for such global security to a nominee of the depositary and except in the circumstances described in the prospectus supplement relating to the debt securities. The specific terms of the depositary arrangement with respect to a series of debt securities will be described in the prospectus supplement relating to such series.

**Modification of the Indenture** 

We and the trustee may modify the indenture with respect to the debt securities of any series, with or without the consent of the holders of debt securities, under certain circumstances to be described in a prospectus supplement.

**Defeasance; Satisfaction and Discharge** 

The prospectus supplement will outline the conditions under which we may elect to have certain of our obligations under the indenture discharged and under which the indenture obligations will be deemed to be satisfied.

**Defaults and Notice** 

The debt securities of any series will contain events of default to be specified in the applicable prospectus supplement, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay the principal of, or premium or make-whole amount, if any, on any debt security of such series when due and payable (whether at maturity, by call for redemption, through any mandatory sinking fund, by redemption at the option of the holder, by declaration of acceleration or otherwise);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to make a payment of any interest on any debt security of such series when due, which failure shall have continued for a period of 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to perform or observe any of our other covenants or agreements in the indenture with respect to the debt securities of such series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain events relating to our bankruptcy, insolvency or reorganization; and certain cross defaults.

If an event of default with respect to debt securities of any series shall occur and be continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding debt securities of such series may declare the principal amount (or, if the debt securities of such series are issued at an original issue discount, such portion of the principal amount as may be specified in the terms of the debt securities of such series) of all debt securities of such series and/or such other amount or amounts as the debt securities or supplemental indenture with respect to such series may provide, to be immediately due and payable.

The trustee under the indenture shall, within 90 days after the occurrence of a default, give to the holders of debt securities of any series notice of all uncured defaults with respect to such series known to it. However, in the case of a default

------

that results from an event other than the failure to make any payment of the principal of, premium or make-whole amount, if any, or interest on the debt securities of any series, or in the payment of any mandatory sinking fund installment with respect to the debt securities of such series, the trustee may withhold giving such notice if it in good faith determines that the withholding of such notice is in the interest of the holders of the debt securities of such series.

The indenture will contain a provision entitling the trustee to be indemnified by holders of debt securities before proceeding to exercise any trust or power under the indenture at the request of such holders. The indenture will provide that the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee, with respect to the debt securities of such series. However, the trustee may decline to follow any such direction if, among other reasons, the trustee determines in good faith that the actions or proceedings as directed may not lawfully be taken, would involve the trustee in personal liability or would be unduly prejudicial to the holders of the debt securities of such series not joining in such direction.

The right of a holder to institute a proceeding with respect to the indenture is subject to certain conditions including, that the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of such series make a written request upon the trustee to exercise its power under the indenture, indemnify the trustee to its satisfaction and afford the trustee reasonable opportunity to act. Even so, the holder has an absolute right to receipt of the principal of, premium or make-whole amount, if any, and interest when due, to require conversion or exchange of debt securities if the indenture provides for convertibility or exchangeability at the option of the holder and to institute suit for the enforcement of such rights.

**Conversion or Exchange Rights** 

If debt securities of any series are convertible or exchangeable, the applicable prospectus supplement will specify:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the type of securities into which they may be converted or exchanged;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the conversion price or exchange ratio, or its method of calculation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether conversion or exchange is mandatory or at the holder's election;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• how and when the conversion price or exchange ratio may be adjusted; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other important terms concerning the conversion or exchange rights.

**Concerning the Trustee** 

The Bank of New York Mellon will serve as the trustee under the indenture pursuant to which any debt securities will be issued. The prospectus supplement with respect to particular debt securities will describe any other relationship that we may have with The Bank of New York Mellon.

**Governing Law** 

The indenture and the debt securities will be governed by the laws of the State of New York.

------

**DESCRIPTION OF WARRANTS**

Please note that in this section entitled "Description of Warrants," references to the "Company," "we," "us," "ours" or "our" refer only to StoneX Group Inc. and not to its consolidated subsidiaries. Also, in this section, references to holders mean those who own warrants registered in their own names, on the books that the Company or its agent maintains for this purpose, and not those who own beneficial interests in warrants registered in street name or in warrants issued in book-entry form through one or more depositaries. Owners of beneficial interests in the warrants should read the section below entitled "Form, Exchange and Transfer—Book-Entry Procedures and Settlement."

**General**

We may offer warrants separately or together with our debt or equity securities.

We may issue warrants in such amounts or in as many distinct series as we wish. This section summarizes terms of the warrants that apply generally to all series. The financial and other specific terms of your warrant and any warrant agreement will be described in the prospectus supplement. Those terms may vary from the terms described here.

The warrants of a series will be issued under a separate warrant agreement to be entered into between us and one or more banks or trust companies, as warrant agent, as set forth in the prospectus supplement. A form of each warrant agreement, including a form of warrant certificate representing each warrant, reflecting the particular terms and provisions of a series of offered warrants, will be filed with the SEC at the time of the offering and incorporated by reference in the registration statement of which this prospectus forms a part. You can obtain a copy of any form of warrant agreement when it has been filed by following the directions outlined in "Where You Can Find More Information" or by contacting the applicable warrant agent.

The following briefly summarizes the material provisions of the warrant agreements and the warrants. As you read this section, please remember that the specific terms of your warrant as described in the prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section. You should read carefully the prospectus supplement and the more detailed provisions of the warrant agreement and the warrant certificate, including the defined terms, for provisions that may be important to you. If there are differences between the prospectus supplement and this prospectus, the prospectus supplement will control. Thus, the statements made in this section may not apply to your warrant.

**Types of Warrants**

We may issue debt warrants or equity warrants. A debt warrant is a warrant for the purchase of our debt securities on terms to be determined at the time of sale. An equity warrant is a warrant for the purchase or sale of our equity securities. We may also issue warrants for the purchase or sale of, or whose cash value is determined by reference to the performance, level or value of, one or more of the following: securities of one or more issuers, including those issued by us and described in this prospectus or debt or equity securities issued by third parties; a currency or currencies; a commodity or commodities; and other financial, economic or other measure or instrument, including the occurrence or non-occurrence of any event or circumstances, or one or more indices or baskets of these items.

**Information in the Prospectus Supplement**

The prospectus supplement will contain, where applicable, the following information about the warrants:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the specific designation and aggregate number of, and the price at which we will issue, the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency or currency unit with which the warrants may be purchased and in which any payments due to or from the holder upon exercise must be made;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the exercise price may be paid in cash, by the exchange of warrants or other securities or both, and the method of exercising the warrants;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the warrants will be settled by delivery of the underlying securities or other property or in cash;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether and under what circumstances we may cancel the warrants prior to their expiration date, in which case the holders will be entitled to receive only the applicable cancellation amount, which may be either a fixed amount or an amount that varies during the term of the warrants in accordance with a schedule or formula;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the warrants will be issued in global or non-global form, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any debt security included in that unit;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the identities of the warrant agent, any depositaries and any paying, transfer, calculation or other agents for the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchange or quotation system on which the warrants or any securities deliverable upon exercise of the warrants may be listed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the warrants are to be sold separately or with other securities, as part of units or otherwise, and if the warrants are to be sold with the securities of another company or other companies, certain information regarding such company or companies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other terms of the warrants.

If warrants are issued as part of a unit, the prospectus supplement will specify whether the warrants will be separable from the other securities in the unit before the warrants expiration date.

No holder of a warrant will, as such, have any rights of a holder of the debt securities, equity securities or other warrant property purchasable under or in the warrant, including any right to receive payment thereunder.

**Additional Information in the Prospectus Supplement for Debt Warrants**

In the case of debt warrants, the prospectus supplement will contain, where appropriate, the following additional information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation, aggregate principal amount, currency and terms of the debt securities that may be purchased upon exercise of the debt warrants; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation, terms and amount of debt securities, if any, to be issued together with each of the debt warrants and the date, if any, after which the debt warrants and debt securities will be separately transferable.

**No Limit on Issuance of Warrants**

The warrant agreements will not limit the number of warrants or other securities that we may issue.

**Modifications** 

We and the relevant warrant agent may, without the consent of the holders, amend each warrant agreement and the terms of each issue of warrants, for the purpose of curing any ambiguity or of correcting or supplementing

any defective or inconsistent provision, or in any other manner that we may deem necessary or desirable and that will not adversely affect the interests of the holders of the outstanding unexercised warrants in any material respect.

We and the relevant warrant agent also may, with the consent of the holders of at least a majority in number of the outstanding unexercised warrants affected, modify or amend the warrant agreement and the terms of the warrants.

No such modification or amendment may, without the consent of each holder of an affected warrant:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the amount receivable upon exercise, cancellation or expiration;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• shorten the period of time during which the warrants may be exercised;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• otherwise materially and adversely affect the exercise rights of the beneficial owners of the warrants; or

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage of outstanding warrants whose holders must consent to modification or amendment of the applicable warrant agreement or the terms of the warrants.

**Merger and Similar Transactions Permitted; No Restrictive Covenants or Events of Default**

The warrant agreements will not restrict our ability to merge or consolidate with, or sell our assets to, another firm or to engage in any other transactions. If at any time there is a merger or consolidation involving us or a sale or other disposition of all or substantially all of our assets, the successor or assuming company will be substituted for us, with the same effect as if it had been named in the warrant agreement and in the warrants. We will be relieved of any further obligation under the warrant agreement or warrants, and, in the event of any such merger, consolidation, sale or other disposition, we as the predecessor corporation may at any time thereafter be dissolved, wound up or liquidated.

The warrant agreements will not include any restrictions on our ability to put liens on our assets, including our interests in our subsidiaries, nor will they provide for any events of default or remedies upon the occurrence of any events of default.

**Warrant Agreements Will Not Be Qualified under Trust Indenture Act**

No warrant agreement will be qualified as an indenture, and no warrant agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of warrants issued under a warrant agreement will not have the protection of the Trust Indenture Act with respect to their warrants.

**Enforceability of Rights by Beneficial Owner**

Each warrant agent will act solely as our agent in connection with the issuance and exercise of the applicable warrants and will not assume any obligation or relationship of agency or trust for or with any registered holder of or owner of a beneficial interest in any warrant. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant certificate, including any duty or responsibility to initiate any proceedings at law or otherwise or to make any demand upon us.

Holders may, without the consent of the applicable warrant agent, enforce by appropriate legal action, on their own behalf, their right to exercise their warrants, to receive debt securities, in the case of debt warrants, and to receive payment, if any, for their warrants, in the case of universal warrants.

**Governing Law**

Unless otherwise stated in the prospectus supplement, the warrants and each warrant agreement will be governed by the laws of the State of New York.

------

**DESCRIPTION OF PREFERRED STOCK**

As of the date of this prospectus, our authorized capital stock includes 1,000,000 shares of preferred stock, none of which were issued and outstanding as of February 19, 2025.

The following briefly summarizes the material terms of our preferred stock, other than pricing and related terms disclosed for a particular issuance in an accompanying prospectus supplement. You should read the particular terms of any series of preferred stock we offer which will be described in more detail in the prospectus supplement prepared for such series, together with the more detailed provisions of our certificate of incorporation and the certificate of designations relating to each particular series of preferred stock, for provisions that may be important to you. The certificate of designations relating to a particular series of preferred stock offered by way of an accompanying prospectus supplement will be filed with the SEC at the time of the offering and incorporated by reference in the registration statement of which this prospectus forms a part. You can obtain a copy of this document by following the directions outlined in "Where You Can Find More Information." The prospectus supplement will also state whether any of the terms summarized below do not apply to the series of preferred stock being offered.

**General**

Under our certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series, and to establish from time to time a series of preferred stock with the following terms specified:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number of shares to be included in the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation, powers, preferences and rights of the shares of the series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the qualifications, limitations or restrictions of such series, except as otherwise stated in the certificate of incorporation.

Prior to the issuance of any series of preferred stock, our board of directors will adopt resolutions creating and designating the series as a series of preferred stock and the resolutions will be filed in a certificate of designations as an amendment to the certificate of incorporation. The term board of directors includes any duly authorized committee.

The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future, provided that the future issuances are first approved by the holders of the class(es) of preferred stock adversely affected. The board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose. Examples of proper corporate purposes include issuances to obtain additional financing in connection with acquisitions or otherwise, and issuances to our officers, directors and employees pursuant to benefit plans or otherwise. Shares of preferred stock we issue may have the effect of rendering more difficult or discouraging an acquisition of us deemed undesirable by our board of directors.

The preferred stock will be, when issued, fully paid and nonassessable. Holders of preferred stock will not have any preemptive or subscription rights to acquire more of our stock.

We will name the transfer agent, registrar, dividend disbursing agent and redemption agent for shares of each series of preferred stock in the prospectus supplement relating to such series.

**Rank**

Unless otherwise specified for a particular series of preferred stock in an accompanying prospectus supplement, each series will rank on an equal basis with each other series of preferred stock, and prior to the common stock, as to dividends and distributions of assets.

------

**Dividends**

Holders of each series of preferred stock will be entitled to receive cash dividends, when, as and if declared by our board of directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books or, on the record dates fixed by the board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative.

We may not declare, pay or set apart for payment dividends on the preferred stock unless full dividends on any other series of preferred stock that ranks on an equal or senior basis have been paid or sufficient funds have been set apart for payment for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all prior dividend periods of the other series of preferred stock that pay dividends on a cumulative basis; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the immediately preceding dividend period of the other series of preferred stock that pay dividends on a noncumulative basis.

Partial dividends declared on shares of preferred stock and any other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for both series of preferred stock.

Similarly, we may not declare, pay or set apart for payment non-stock dividends or make other payments on the common stock or any other of our stock ranking junior to the preferred stock until full dividends on the preferred stock have been paid or set apart for payment for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all prior dividend periods if the preferred stock pays dividends on a cumulative basis; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the immediately preceding dividend period if the preferred stock pays dividends on a noncumulative basis.

**Conversion and Exchange**

The prospectus supplement for any series of preferred stock will state the terms, if any, on which shares of that series are convertible into or exchangeable for shares of our common stock.

**Redemption**

If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or at the option of the holder thereof and may be mandatorily redeemed.

Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable.

Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of such shares will terminate except for the right to receive the redemption price.

**Liquidation Preference**

Upon our voluntary or involuntary liquidation, dissolution or winding up, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount set forth in the prospectus supplement relating to such series of preferred stock, plus an amount equal to any accrued and unpaid dividends. Such distributions will be made before any distribution is made on any securities ranking junior relating to preferred stock in liquidation, including common stock.

If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of such series and such other securities will share in any such distribution of our available assets on a ratable basis in proportion to the full liquidation preferences. Holders of such series of preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.

------

**Voting Rights**

The holders of shares of our preferred stock will have no voting rights, except:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• as otherwise stated in the prospectus supplement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• as otherwise stated in the certificate of designations establishing such series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• as required by applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms of the units and of the warrants, debt securities, preferred shares and common shares comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a description of the terms of any unit agreement governing the units;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• description of the provisions for the payment, settlement, transfer or exchange or the units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any applicable U.S. federal income tax consequences.

The terms and conditions described under "Description of Debt Securities," "Description of Warrants," "Description of Preferred Stock," and "Description of Common Stock" will apply to each unit and to any warrants, shares of preferred stock, shares of common stock or debt securities issued by us included in each unit, as applicable, unless otherwise specified in the applicable prospectus supplement.

We will issue the units under one or more unit agreements, each referred to as a Unit Agreement, to be entered into between us and a bank or trust company, as unit agent. The specific terms of any Unit Agreement will be described in the applicable prospectus supplement. We may issue units in one or more series, which will be described in the applicable prospectus supplement.

Each holder of common stock is entitled to one vote per share for the election of directors and for all other matters to be voted on by stockholders. Except as otherwise provided by law, the holders of common stock vote as one class together with holders of our preferred stock (if they have voting rights). Holders of common stock may not cumulate their votes in the election of directors, and are entitled to share equally in the dividends that may be declared by the board of directors, but only after payment of dividends required to be paid on outstanding shares of preferred stock.

Upon our voluntary or involuntary liquidation, dissolution or winding up, holders of common stock share ratably in the assets remaining after payments to creditors and provision for the preference of any preferred stock. There are no preemptive or other subscription rights, conversion rights or redemption or scheduled installment payment provisions relating to shares of our common stock. All of the outstanding shares of our common stock are fully paid and non-assessable. The transfer agent and registrar for the common stock is BNY Mellon Shareowner Services. The common stock is listed on the NASDAQ Global Select Market under the symbol "SNEX".

**Delaware Law, Certificate of Incorporation and By-Law Provisions that May Have an Antitakeover Effect**

The following discussion concerns certain provisions of Delaware law and our certificate of incorporation and by-laws that may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interest, including offers or attempts that might result in a premium being paid over the market price for its shares.

*Delaware Law*. We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prior to the business combination the corporation's board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the stockholder owned at least 85% of the outstanding voting stock of the corporation at the time the transaction commenced, excluding for the purpose of determining the number of shares outstanding those shares owned by the corporation's officers and directors and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at or subsequent to the time the business combination is approved by the corporation's board of directors and authorized at an annual or special meeting of its stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of its outstanding voting stock which is not owned by the interested stockholder.

A business combination includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An interested stockholder is a person who, together with affiliates and associates, owns (or within three years did own) 15% or more of the corporation's voting stock.

*Certificate of Incorporation and By-Laws*. Our by-laws provide that special meetings of stockholders may be called by our Secretary only at the request of the President, a majority of our board of directors or the holders of not less than one-fifth of all the shares issued and outstanding and entitled to vote at the particular meeting. Written notice of a special meeting stating the place, date and hour of the meeting and the purposes for which the meeting is called must be given between 10 and 60 days before the date of the meeting, and only business specified in the notice may come before the meeting. In addition, our by-laws provide that directors be elected by a plurality of votes cast at an annual meeting and does not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors.

------

**FORM, EXCHANGE AND TRANSFER**

Each debt security, equity security, warrant, and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Both certificated securities in definitive form and global securities will be issued only in registered form.

Definitive securities name you or your nominee as the owner of the security, and, in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor's beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below under "- Global Securities."

Our obligations, as well as the obligations of the trustee under any indenture and the obligations, if any, of any warrant agents and unit agents and any other agents of ours, any agents of the trustee or any agents of any warrant agents or unit agents, run only to the persons or entities named as holders of the securities in the relevant security register. Neither we nor any trustee, warrant agent, unit agent, other agent of ours, agent of the trustee or agent of the warrant agents or unit agents have obligations to investors who hold beneficial interest in global securities, in street name or by any other indirect means.

Upon making a payment or giving a notice to the holder as required by the terms of that security, we will have no further responsibility for that payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect owners of beneficial interests in that security but does not do so. Similarly, if we want to obtain the approval or consent of the holders of any securities for any purpose, we would seek the approval only from the holders, and not the indirect owners, of the relevant securities. Whether and how the holders contact the indirect owners would be governed by the agreements between such holders and the indirect owners.

References to you in this prospectus refer to those who invest in the securities being offered by this prospectus, whether they are the direct holders or only indirect owners of beneficial interests in those securities.

**Global Securities**

We may issue debt securities, equity securities, warrants and units in the form of one or more global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or its nominee. In those cases, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a global security may not be transferred except as a whole by and among the depositary for the global security, the nominees of the depositary or any successors of the depositary or those nominees.

Debt securities issued in registered global form primarily outside the United States will be deposited with a common safekeeper for Euroclear and/or Clearstream, Luxembourg and will be registered in the name of a nominee of the common safekeeper. We anticipate that the provisions described under The Depositary section below will apply to all other depositary arrangements, unless otherwise described in the prospectus supplement relating to those securities.

**The Depositary**

Except as otherwise described herein or in the applicable prospectus supplement, The Depository Trust Company, New York, New York (the "Depositary") will be designated as the depositary for any registered global security. Each registered global security will be registered in the name of Cede & Co., the Depositary's nominee.

The Depositary is a limited-purpose trust company organized under the New York Banking Law, a banking organization within the meaning of the New York Banking Law, a member of the Federal Reserve System, a clearing corporation within the meaning of the New York Uniform Commercial Code, and a clearing agency registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities deposited with it by its direct participants, and it facilitates the settlement of transactions among its direct participants in those securities through electronic computerized book-entry changes in participants' accounts, eliminating the need for physical movement of securities certificates. The Depositary's direct participants

------

include both U.S. and non-U.S. securities brokers and dealers, including the agents, banks, trust companies, clearing corporations and other organizations, some of whom and/or their representatives own the Depositary. Access to the Depositary's book-entry system is also available to others, such as both U.S. and non-U.S. brokers and dealers, banks, trust companies and clearing corporations, such as Euroclear and Clearstream, Luxembourg that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to the Depositary and its participants are on file with the SEC.

Purchases of the securities under the Depositary's system must be made by or through its direct participants, which will receive a credit for the securities on the Depositary's records. The ownership interest of each actual purchaser of each security (the "beneficial owner") is in turn to be recorded on the records of direct and indirect participants. Beneficial owners will not receive written confirmation from the Depositary of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through which the beneficial owner entered into the transaction. Transfers of ownership interests in the securities are to be made by entries on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in securities, except in the event that use of the book-entry system for the securities is discontinued.

To facilitate subsequent transfers, all securities deposited with the Depositary are registered in the name of the Depositary's partnership nominee, Cede & Co., or such other name as may be requested by the Depositary. The deposit of securities with the Depositary and their registration in the name of Cede & Co. or such other nominee of the Depositary do not affect any change in beneficial ownership. The Depositary has no knowledge of the actual beneficial owners of the securities; the Depositary's records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by the Depositary to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither the Depositary nor Cede & Co. (nor such other nominee of the Depositary) will consent or vote with respect to the securities unless authorized by a direct participant in accordance with the Depositary's procedures. Under its usual procedures, the Depositary mails an omnibus proxy to us as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants identified in a listing attached to the omnibus proxy to whose accounts the securities are credited on the record date.

Redemption proceeds, distributions, and dividend payments on the securities will be made to Cede & Co. or such other nominee as may be requested by the Depositary. The Depositary's practice is to credit direct participants accounts upon the Depositary's receipt of funds and corresponding detail information from us or any agent of ours, on the date payable in accordance with their respective holdings shown on the Depositary's records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in street name, and will be the responsibility of such participant and not of the Depositary or its nominee, the trustee, any agent of ours, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payments of redemption proceeds, distributions, and dividend payments to Cede & Co. or such other nominee as may be requested by the Depositary is the responsibility of us or of any paying agent of ours, disbursement of such payments to direct participants will be the responsibility of the Depositary, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

The Depositary may discontinue providing its services as depositary with respect to the securities at any time by giving reasonable notice to us or our agent. Under such circumstances, in the event that a successor depositary is not obtained by us within 90 days, security certificates are required to be printed and delivered. In addition, under the terms of the indentures, we may at any time and in our sole discretion decide not to have any of the securities represented by one or more registered global securities. We understand, however, that, under current

industry practices, the Depositary would notify its participants of our request, but will only withdraw beneficial interests from a global security at the request of each participant. We would issue definitive certificates in exchange for any such interests withdrawn. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the Depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the Depositary's instructions will be based upon directions received by the Depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the Depositary.

------

According to the Depositary, the foregoing information relating to the Depositary has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

The information in this section concerning the Depositary and Depositary's book-entry system has been obtained from sources we believe to be reliable, but we take no responsibility for the accuracy thereof. The Depositary may change or discontinue the foregoing procedures at any time.

**Book-Entry Procedures and Settlement**

The securities will be issued in the form of one or more fully registered global securities which will be deposited with, or on behalf of the Depositary, and registered in the name of Cede & Co. Beneficial interests in the registered global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in the Depositary, as described above. Investors may elect to hold interests in the registered global securities held by the Depositary through Clearstream, Luxembourg or Euroclear if they are participants in those systems, or indirectly through organizations which are participants in those systems. Clearstream, Luxembourg and Euroclear will hold interests on behalf of their participants through customers' securities accounts in Clearstream, Luxembourg's and Euroclear's names on the books of their respective depositaries, which in turn will hold interests in the registered global securities in customers' securities accounts in the depositaries names on the books of the Depositary. Citibank, N.A. will act as depositary for Clearstream, Luxembourg, and The Bank of New York Mellon, a New York banking corporation, will act as depositary for Euroclear. We refer to each of Citibank, N.A. and The Bank of New York Mellon, acting in this depositary capacity, as the U.S. depositary for the relevant clearing system. Except as set forth below, the registered global securities may be transferred, in whole but not in part, only to the Depositary, another nominee of the Depositary or to a successor of the Depositary or its nominee.

Clearstream, Luxembourg advises that distributions with respect to the securities held through Clearstream, Luxembourg will be credited to cash accounts of Clearstream, Luxembourg customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream, Luxembourg.

Euroclear advises that distributions with respect to the securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the terms and conditions, to the extent received by the U.S. depositary for Euroclear.

Euroclear further advises that investors that acquire, hold and transfer interests in securities by book-entry through accounts with Euroclear or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between their intermediary and each other intermediary, if any, standing between themselves and the securities.

Individual certificates in respect of the securities will not be issued in exchange for the registered global securities, except in very limited circumstances. If the Depositary notifies us that it is unwilling or unable to continue as a clearing system in connection with the registered global securities or ceases to be a clearing agency registered under the Exchange Act, and a successor clearing system is not appointed by us within 90 days after receiving that notice from the Depositary or upon becoming aware that the Depositary is no longer so registered, we will issue or cause to be issued individual certificates in registered form on registration of transfer of, or in exchange for, book-entry interests in the securities represented by registered global securities upon delivery of those registered global securities for cancellation.

Title to book-entry interests in the securities will pass by book-entry registration of the transfer within the records of Clearstream, Luxembourg, Euroclear or the Depositary, as the case may be, in accordance with their respective procedures. Book-entry interests in the securities may be transferred within Clearstream, Luxembourg and within Euroclear and between Clearstream, Luxembourg and Euroclear in accordance with procedures established for these purposes by Clearstream, Luxembourg and Euroclear. Book-entry interests in the securities may be transferred within the Depositary in accordance with procedures established for this purpose by the Depositary. Transfers of book-entry interests in the securities among Clearstream, Luxembourg and Euroclear and the Depositary may be effected in accordance with procedures established for this purpose by Clearstream, Luxembourg, Euroclear and the Depositary.

**Global Clearance and Settlement Procedures**

Initial settlement for the securities offered on a global basis through the Depositary will be made in immediately available funds. Secondary market trading between the Depositary's participants will occur in the ordinary way in accordance

------

with the Depositary's rules and will be settled in immediately available funds using the Depositary's Same-Day Funds Settlement System. Secondary market trading between Clearstream, Luxembourg customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream, Luxembourg and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through the Depositary on the one hand, and directly or indirectly through Clearstream, Luxembourg customers or Euroclear participants, on the other, will be effected through the Depositary in accordance with the Depositary's rules on behalf of the relevant European international clearing system by its U.S. depositary; however, these cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in the clearing system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering interests in the securities to or receiving interests in the securities from the Depositary, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to the Depositary. Clearstream, Luxembourg customers and Euroclear participants may not deliver instructions directly to their respective U.S. depositaries.

Because of time-zone differences, credits of interests in the securities received in Clearstream, Luxembourg or Euroclear as a result of a transaction with a Depositary participant will be made during subsequent securities settlement processing and dated the business day following the Depositary settlement date. Credits of interests or any transactions involving interests in the securities received in Clearstream, Luxembourg or Euroclear as a result of a transaction with a Depositary participant and settled during subsequent securities settlement processing will be reported to the relevant Clearstream, Luxembourg customers or Euroclear participants on the business day following the Depositary settlement date. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales of interests in the securities by or through a Clearstream, Luxembourg customer or a Euroclear participant to a Depositary participant will be received with value on the Depositary settlement date but will be available in the relevant Clearstream, Luxembourg or Euroclear cash account only as of the business day following settlement in the Depositary.

Although the Depositary, Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of interests in the securities among participants of the Depositary, Clearstream, Luxembourg and Euroclear, they are under no obligation to perform or continue to perform the foregoing procedures and these procedures may be changed or discontinued at any time.

**USE OF PROCEEDS**

Unless otherwise set forth in the applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities we offer by this prospectus for general corporate purposes, which may include, among other things: additions to working capital; the redemption or repurchase of outstanding equity and debt securities; the repayment of indebtedness; and the expansion of our business through internal growth or acquisitions.

We may raise additional funds from time to time through equity or debt financing, including borrowings under credit facilities, to finance our business and operations.

**PLAN OF DISTRIBUTION**

We may offer the securities to or through underwriters or dealers, by ourselves directly, through agents, or through a combination of any of these methods of sale. Any such underwriters, dealers or agents may include our affiliates. The details of any such offering will be set forth in the any prospectus supplement relating to the offering.

We may sell any series of debt securities, common stock, preferred stock and depositary shares being offered directly to one or more purchasers, through agents, to or through underwriters or dealers, or through a combination of any such methods of sale. The distribution of the securities may be effected from time to time in one or more transactions at fixed prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The prospectus supplement will set forth the terms of the offering, including the names of any underwriters, dealers or agents, the purchase price of such securities and the proceeds to us from such sale, any underwriting discounts and commissions or agency fees and other items constituting underwriters' or agents' compensation, any initial public offering price and any discounts or concessions allowed or paid to dealers or any securities exchange on which such securities may be listed. Any initial public offering price, discounts or concessions allowed or paid to dealers may be changed from time to time.

------

Any discounts, concessions or commissions received by underwriters or agents and any profits on the resale of securities by them may be deemed to be underwriting discounts and commissions under the Securities Act. Unless otherwise set forth in the applicable prospectus supplement, the obligations of underwriters to purchase the offered securities will be subject to certain conditions precedent, and such underwriters will be obligated to purchase all such securities, if any are purchased. Unless otherwise indicated in the applicable prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

We may also offer and sell securities, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms referred to as remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters under the Securities Act in connection with the securities they remarket.

We may authorize underwriters, dealers or other persons acting as agents for us to solicit offers by certain institutions to purchase securities from us, pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by us. The obligations of any purchaser under any such contract will be subject to the conditions that the purchase of the offered securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts.

We may authorize underwriters, dealers or other persons acting as agents for us to make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through The NASDAQ Global Select Market, the existing trading market for our common stock, or sales made to or through a market maker other than on an exchange.

In connection with the offering of securities, we may grant to the underwriters an option to purchase additional securities to cover over-allotments at the initial public offering price, with an additional underwriting commission, as may be set forth in the accompanying prospectus supplement. If we grant any over-allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement for such securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

The securities may be a new issue of securities that have no established trading market. Any underwriters to whom securities are sold for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. Such securities may or may not be listed on a national securities exchange. No assurance can be given as to the liquidity of or the existence of trading markets for any securities.

We may indemnify agents, underwriters, dealers and remarketing firms against certain liabilities, including liabilities under the Securities Act. Our agents, underwriters, dealers and remarketing firms, or their affiliates, may be customers of, engage in transactions with or perform services for us, in the ordinary course of business.

**LEGAL MATTERS**

Unless otherwise specified in the prospectus supplement accompanying this prospectus, the validity of the securities and certain other legal matters will be passed upon for us by Davis Polk & Wardwell LLP, New York, New York. Any underwriters, dealers or agents will be advised about the validity of the securities and other legal matters by their own counsel, which will be named in the prospectus supplement.

**__________________________________________ Offering Note(s)**

&nbsp;&nbsp;&nbsp;&nbsp;(1) In accordance with Rules 456(b) and 457(r) under the Securities Act of 1933, as amended (the "Securities Act"), StoneX Group Inc. (the "Company") initially deferred payment of all of the registration fees for the Registration Statement on Form S-3 (Registration No. 333-285071), filed with the Securities and Exchange Commission (the "SEC") on February 20, 2025.
