Marex wins consent to amend 2029 notes terms

Marex Group plc has successfully completed a consent solicitation for its 6.404% Senior Notes due 2029 and entered into a Fourth Supplemental Indenture.

Rhea-AI Filing Summary

Marex Group plc has successfully completed a consent solicitation for its 6.404% Senior Notes due 2029 and entered into a Fourth Supplemental Indenture. Holders representing more than a majority of the notes approved amendments that allow a Bermuda or similar holding company to assume Marex’s obligations under the notes and indenture.

Consenting holders will receive a cash payment of $1.00 per $1,000 principal amount, expected to be paid on May 19, 2026. The changes align the 2029 notes with Marex’s other SEC‑registered notes and support its previously announced plan to redomicile the parent holding company to Bermuda, subject to shareholder, court and regulatory approvals.

Insights

Capital structure and credit analyst

Marex secures noteholder consent to align 2029 notes with redomiciliation plans.

Marex obtained majority consents from holders of its 6.404% Senior Notes due 2029 to amend the governing indenture. The Fourth Supplemental Indenture permits a Bermuda holding company to assume obligations on these notes, consistent with Marex’s other SEC‑registered notes.

The company will pay a $1.00 consent fee per $1,000 principal to participating holders, a modest cost to secure flexibility for its proposed move of the parent company’s domicile to Bermuda. That redomiciliation still depends on shareholder, court and regulatory approvals.

For creditors, the filing clarifies that, if approvals are obtained, a new Bermuda parent may become issuer of the 2029 notes on terms aligned with the 2028 and 2031 series. Subsequent company filings about the proposed redomiciliation will provide further detail on timing and structure.

6 terms

Consent Solicitation financial

"pursuant to the Company’s previously announced solicitation of consents for the Notes (the “Consent Solicitation”)."

A consent solicitation is a formal request sent to shareholders or creditors asking them to sign off on a proposed corporate change—such as altering governance rules, approving a deal, or waiving contract terms—without holding a full meeting. It matters to investors because it can quickly change their rights, voting power or the company’s direction, much like asking neighbors to sign a petition to alter a shared fence rather than discussing it at a community meeting.

Fourth Supplemental Indenture financial

"entered into a fourth supplemental indenture to the Indenture (the “Fourth Supplemental Indenture”) governing the Notes"

Proposed Redomiciliation financial

"its proposal to change the legal domicile of its parent holding company to Bermuda from England and Wales (the “Proposed Redomiciliation”)"

Senior Notes financial

"its 6.404% Senior Notes due 2029 (the “Notes”)"

Senior notes are a type of loan that a company borrows from investors, promising to pay it back with interest. They are called "senior" because in case the company faces financial trouble, these lenders are paid back before others. This makes senior notes safer for investors compared to other types of loans or bonds.

Structured Notes financial

"other SEC-registered structured notes (the “Structured Notes” and, together with the 2031 Notes and the 2028 Notes, the “Other Existing SEC-Registered Notes”)"

Structured notes are investment contracts issued by banks that combine a regular loan-like component with a payment formula tied to the performance of stocks, indexes, interest rates or other assets. Think of them as a customized financial recipe: they can offer higher potential returns or partial downside protection compared with a plain bond, but those benefits depend on complex terms and the issuer’s ability to pay. Investors should care because structured notes mix market exposure with issuer credit risk, limited liquidity and fees, so outcomes can be hard to predict and may differ from plain stock or bond investments.

forward-looking statements regulatory

"This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995."

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What did Marex Group plc (MRX) announce regarding its 6.404% Senior Notes due 2029?

Marex announced that holders of its 6.404% Senior Notes due 2029 approved amendments to the indenture. These changes allow a qualifying Bermuda holding company to assume the notes, supporting Marex’s proposed redomiciliation and aligning terms with its other SEC‑registered notes.

What incentive did Marex (MRX) offer noteholders in the consent solicitation?

Marex offered a cash consent payment of $1.00 per $1,000 principal amount of notes to holders who validly consented before the May 15, 2026 expiration. The company expects to pay this consent fee on May 19, 2026, to those eligible holders.

How does the Fourth Supplemental Indenture affect Marex’s 2029 notes?

The Fourth Supplemental Indenture amends the 2029 notes’ indenture to permit a Bermuda or specified‑jurisdiction holding company to assume Marex’s obligations. That holding company may then succeed Marex as issuer and obligor on the notes, once the supplemental indenture is effective.

How is Marex’s proposed redomiciliation connected to the 2029 notes amendments?

Marex plans to change its parent holding company’s legal domicile to Bermuda and reorganize the group into regional sub‑groups. The 2029 notes amendments ensure a new Bermuda parent could assume these notes on consistent terms if shareholder, court and regulatory approvals are obtained.

Did Marex (MRX) disclose whether the consent solicitation met the required threshold?

Yes. As of the expiration date, Marex reported consents from holders representing in excess of the majority of the outstanding aggregate principal. This majority level is sufficient under the indenture to implement the proposed amendments to the 6.404% Senior Notes due 2029.

Are Marex’s 2029 notes now aligned with its other SEC‑registered notes?

The approved amendments align the 2029 notes’ assumption provisions with Marex’s 5.680% 2031 notes, 5.829% 2028 notes and other structured notes. Each now permits a qualifying Bermuda holding company to assume obligations under their respective indentures on a similar basis.

Completion of Consent Solicitation for 6.404% Senior Notes due 2029; Entry into Fourth Supplemental Indenture

On May 18, 2026, Marex Group plc (the “Company”) issued a press release announcing it has received the requisite consents from registered holders of its 6.404% Senior Notes due 2029 (the “Notes”) to approve certain proposed amendments (the “Proposed Amendments”) to the Senior Indenture, dated as of October 15, 2024, as supplemented by the First Supplemental Indenture, dated as of November 4, 2024 (together, the “Indenture”), each between the Company and Citibank, N.A., as the trustee (the “Trustee”), pursuant to the Company’s previously announced solicitation of consents for the Notes (the “Consent Solicitation”). The Consent Solicitation expired at 5:00 p.m., New York City time, on May 15, 2026.

The Fourth Supplemental Indenture became effective and operative immediately upon its execution.

Marex Group plc announces successful completion of consent solicitation for its 6.404% Senior Notes due 2029

May 18, 2026

NEW YORK, May 18, 2026 (GLOBE NEWSWIRE) – Marex Group plc (Nasdaq: MRX) (“Marex” or the “Company”), a diversified global financial services platform, announced today that it has received the requisite consents from registered holders of its 6.404% Senior Notes due 2029 (the “Notes”) to approve certain proposed amendments (the “Proposed Amendments”) to the Indenture, dated as of October 15, 2024 (the “Base Indenture”), as supplemented by the First Supplemental Indenture, dated as of November 4, 2024 (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), each between Marex and Citibank, NA, as the trustee (the “Trustee”), pursuant to the Company’s previously announced solicitation of consents for the Notes (the “Consent Solicitation”). As used in this press release, the term “Group” refers to Marex Group plc, together with its consolidated subsidiaries, as a consolidated entity.

The Consent Solicitation was made pursuant to the terms and conditions set forth in the consent solicitation statement dated May 7, 2026 (the “Consent Solicitation Statement”), and expired at 5:00 p.m., New York City time, on May 15, 2026 (the “Expiration Date”). Subject to the terms and conditions set forth in the Consent Solicitation Statement, holders of the Notes who validly delivered (and did not validly revoke) consents prior to the Expiration Date will receive a cash payment equal to $1.00 per $1,000 principal amount of the Notes (the “Consent Payment”) for which such consents were delivered (and not validly revoked). The Company expects to pay such holders the Consent Payment on May 19, 2026 (the “Settlement Date”). Holders who failed to validly deliver (or who validly revoked) their consents on or prior to the Expiration Date will not be entitled to receive the Consent Payment.

On March 26, 2026, Marex announced its proposal to change the legal domicile of its parent holding company to Bermuda from England and Wales (the “Proposed Redomiciliation”) and to reorganize the Group. If the requisite shareholder, court and regulatory approvals are obtained, the Proposed Redomiciliation will result in the reorganization of all Group subsidiaries into four regional sub-groups (UK, US, EMEA and Rest of World) under a new Bermuda parent holding company (“New ParentCo”).

As previously announced by Marex, consent was sought from holders of the Notes with respect to the Proposed Amendments to align the terms of the Notes and the Indenture with the existing terms of the Company’s recently issued 5.680% Senior Notes due 2031 (the “2031 Notes”) and the relevant indentures governing the 2031 Notes (the “2031 Notes Indenture”). The Proposed Amendments permit a holding company of the Group that is incorporated in the UK overseas territory of Bermuda, such as New ParentCo, to assume the Company’s obligations under the Notes and Indenture, and succeed to, and be substituted for, the Company as issuer and obligor under the Notes and Indenture, in the same manner as such holding company or New ParentCo is permitted under the terms of the 2031 Notes, the Company’s 5.829% Senior Notes due 2028 (the “2028 Notes”) and other SEC-registered structured notes (the “Structured Notes” and, together with the 2031 Notes and the 2028 Notes, the “Other Existing SEC-Registered Notes”) and the relevant indentures governing the Other Existing SEC-Registered Notes (the “Other Existing SEC-Registered Note Indentures”) to assume the Company’s obligations under the Other Existing SEC-Registered Notes and the Other Existing SEC-Registered Note Indentures, and succeed to, and be substituted for, the Company as issuer and obligor thereunder. If the requisite shareholder, court and regulatory approvals are obtained, then, following the Proposed Redomiciliation, New ParentCo may assume the Notes and, upon such assumption, succeed to and be substituted for Marex Group plc, as obligor under and issuer of the Notes.

As reported by the Information and Tabulation Agent, as of the Expiration Date, holders representing in excess of the majority of the outstanding aggregate principal of the Notes validly delivered (and not validly revoked) consents pursuant to the Consent Solicitation. The consents received in the Consent Solicitation are sufficient to effect the Proposed Amendments to the indenture governing the Notes. Accordingly, the Company intends to execute and deliver to the Trustee on the Settlement Date, a fourth supplemental indenture to the Indenture (the “Fourth Supplemental Indenture”) to effect the Proposed Amendments. The Proposed Amendments will become effective and operative upon the execution by the Company and Trustee of the Fourth Supplemental Indenture.
