Marex Group Ltd (MRX) SEC Filings, Jul 6-9, 2026

Marex Group Limited is offering Capped Leveraged Buffered Notes linked to the S&P 500® Index due August 3, 2028. Each Note has a $1,000 Principal Amount and a Final Valuation Date of July 31, 2028. The Notes provide an Upside Participation Rate of 150% (1.50x) subject to a Maximum Return of 24.00%, and include a Buffer Percentage of -10.00% (Buffer Amount 10.00%). If the Reference Return is below the Buffer Percentage, loss is 1% of principal for each 1% index decline beyond 10%, up to a potential loss of 90% of principal. The Estimated Initial Value on the Trade Date is expected to be between $950.00 and $990.00 per Note, which the document states will be less than the price to public. Marex has applied to list the Notes on the Vienna MTF. The Notes are senior unsecured obligations of Marex and are subject to Marex credit risk and other risks discussed in the "Risk Factors" sections.

Marex Group Limited is offering Contingent Income (with Memory) Barrier Notes linked to the worst performing common stock of GE Vernova Inc., General Motors Company and Intuitive Surgical, Inc.. The Notes have a $1,000 principal amount per note, a Pricing Date of July 28, 2026, a Trade Date of July 29, 2026, an Original Issue Date of July 31, 2026 and a scheduled Maturity Date of August 2, 2029.

The Notes pay a monthly contingent coupon (with memory) if each underlying’s Closing Price on a Coupon Determination Date is at or above its Coupon Trigger (50.00% of Initial Value). The stated monthly coupon equals at least $15.67 per $1,000 (1.567% monthly, equivalent to 18.804% per annum), to be fixed on the Trade Date. At maturity the holder receives $1,000 plus the final contingent coupon if the Worst Performing Underlying’s Reference Return is greater than or equal to -50.00%; otherwise the maturity payment equals $1,000 plus ($1,000 × Reference Return), exposing holders to up to 100% principal loss if the Final Value is below the Barrier Value (50.00% of Initial Value).

Marex Group Limited is offering Autocallable Contingent Income Barrier Notes linked to the MerQube US Large‑Cap Vol Advantage Index due July 31, 2031. The Notes pay a quarterly Contingent Coupon of $39.25 per $1,000 (3.925% per quarter; 15.70% per annum) only if the Reference Asset meets the Coupon Trigger on each determination date, and may be automatically called if the Reference Asset closes at or above its Call Threshold (100% of Initial Value) on any Call Observation Date. If the Notes are not called, payment at maturity depends on the Reference Return: holders receive $1,000 plus the final Contingent Coupon when the Reference Return is greater than or equal to -40.00%, but will suffer a dollar‑for‑dollar loss below that level (up to 100% loss of principal). The Notes reflect Marex’s credit risk, include a daily 6.0% per annum decrement in the Reference Asset calculation and reference a volatility‑targeting strategy (35% target) that can employ up to 500% exposure; investors should review the Risk Factors and tax discussion in the prospectus materials.

Marex Group Limited has completed a corporate reorganization that makes a new Bermuda company the parent of the Marex group. On July 1, 2026, holders of ordinary shares in the former parent, Marex Group plc, received ordinary shares in Marex Group Limited on a one-for-one basis, and the former parent became a wholly owned subsidiary.

The former parent has been renamed Marex UK Holdings Limited and converted into a private limited company in England and Wales. Following this redomiciliation, Marex Group Limited filed post-effective amendments to existing shelf registration statements and, on July 6, 2026, entered into multiple supplemental indentures so it now directly assumes all obligations under the group’s senior notes, structured notes, subordinated notes and contingent capital convertible securities.
