Exhibit 10.2

Second Supplemental Indenture

    THIS SECOND SUPPLEMENTAL INDENTURE, dated as of April 21, 2022 (this “Supplemental Indenture”), by and among StoneX Payment Services Ltd., a Washington profit corporation (the “Guaranteeing Subsidiary”), StoneX Group Inc. (formerly known as INTL FCStone Inc.), a Delaware corporation (the “Issuer”), the Guarantors party to the Indenture (as defined below) and The Bank of New York Mellon, as trustee (in such capacity, the “Trustee”) and collateral agent (in such capacity, the “Collateral Agent”).

W I T N E S S E T H:

    WHEREAS, the Issuer and the Guarantors party thereto from time to time have heretofore executed and delivered to the Trustee the Indenture, dated as of June 11, 2020 (as amended, supplemented or otherwise modified to the date of this Supplemental Indenture, the “Indenture”), governing the Issuer’s 8.625% Senior Secured Notes due 2025 (the “Notes”);

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee and the Collateral Agent a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee and the Collateral Agent are authorized to execute and deliver this Supplemental Indenture without the consent of any Holder.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

1.CAPITALIZED TERMS. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Indenture.

2.AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide a full and unconditional Guarantee on the terms and subject to the conditions set forth in the Indenture, including, without limitation, Article 11 thereof.

3.NO RECOURSE AGAINST OTHERS. No director, officer, employee, partner (including, for greater certainty, any general partner of any general partnership who is an individual person), incorporator, manager, stockholder or member of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Issuer, the Guaranteeing Subsidiary or any other Guarantors under the Indenture Documents or this Supplemental Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws.

5.COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture manually, electronically or by facsimile. Each signed copy or counterpart shall be an original, but all of them together represent the same agreement. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or portable document format transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture and signature pages for all purposes.

E-1

Signatures of the parties hereto transmitted by facsimile or portable document format shall be deemed to be their original signatures for all purposes.

6.EFFECT OF HEADINGS. The section headings herein are for convenience only and shall not affect the construction hereof.

7.RATIFICATION OF INDENTURE; SUPPLEMENTAL INDENTURES PART OF INDENTURE. Except as expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and each Holder of Notes heretofore or hereafter authenticated and delivered shall be bound hereby.

8.TRUSTEE. Neither the Trustee nor the Collateral Agent shall be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Issuer.
