## Exhibit 99.1

Marex Group plc announces first quarter 2026 results

NEW YORK, May 6, 2026 (GLOBE NEWSWIRE) – Marex Group plc ('Marex' or the 'Group'; Nasdaq: MRX) a diversified global financial services platform, providing market access, infrastructure services and essential liquidity, to clients across global markets, today reported financial results for the first quarter ('Q1 2026').

Ian Lowitt, Group Chief Executive Officer, stated: "This record result demonstrates the strength and resilience of our diversified business and our ability to continue to deliver consistent growth. This is our eighth quarter as a public company, and every quarter has demonstrated year-on-year profit growth, which illustrates our strengthening franchise. While all of our businesses performed well in the first quarter, elevated volatility supported particularly strong results in Market Making and Hedging and Investment Solutions. Performance in April has been positive thanks to favorable trading conditions and the continued growth of our platform. While we do not expect the extreme volatility seen in the first quarter to persist, thanks to the diversified business we have built we remain confident in our outlook for the full year."

---

1.&nbsp;&nbsp;&nbsp;&nbsp;For analysis purposes, average headcount is used in the performance commentary outlined below.

2. Headcount table represents headcount for continuing operations and FTE associated with the Group's discontinued operation have been excluded for comparability.

Performance for the three months ended March 31, 2026

Revenue increased by $225.0m to $692.3m (Q1 2025: $467.3m), a record first quarter, with broad-based revenue growth across all four business segments reflecting increased business with a growing number of clients alongside a supportive market environment.

Net trading income more than doubled, increasing by $173.2m to $332.3m (Q1 2025: $159.1m), driven by higher client activity and favorable market conditions across Market Making ($71.6m), Hedging and Investment Solutions ($62.9m) and Agency and Execution ($60.1m).

Net commission income increased by $45.0m to $295.7m (Q1 2025: $250.7m), driven by Clearing ($20.3m) and Agency and Execution ($24.7m) as heightened volatility resulted in increased volumes principally in the energy, securities and metals markets.

Net physical commodities income increased by $19.3m to $23.4m (Q1 2025: $4.1m) primarily from physical recycled metals, reflecting an increase in client demand.

Net interest income decreased by $12.5m to $40.9m (Q1 2025: $53.4m). Interest income grew, reflecting higher average balances of $22.1bn (Q1 2025: $17.1bn) which more than offset a 70 bps reduction in the average Fed Funds rate. However, higher interest expenses related to the Group's $500m senior debt issuance (May 2025) and structured note issuance in Hedging and Investment Solutions brought net interest income lower overall.

Total expenses increased by $165.8m to $539.2m (Q1 2025: $373.4m), reflecting strong revenue performance which resulted in higher performance related pay and ongoing investment to support growth including the costs associated with acquisitions completed after Q1 2025, principally Aarna, Hamilton Court, Winterflood and Agrinvest.

Compensation and benefits increased by $129.1m to $420.8m (Q1 2025: $291.7m) reflecting higher performance related pay and a higher average FTE headcount.

Other expenses increased by $32.9m to $106.7m (Q1 2025: $73.8m) driven by the impact of acquisitions and continued investment in our technology infrastructure to accelerate business growth, alongside higher professional fees.

Reported Profit Before Tax increased by $51.8m to $149.8m (Q1 2025: $98.0m), with margin improving to 21.6% (Q1 2025: 21.0%), driven by margin growth across Agency and Execution, Market Making and Solutions. Adjusting items were $2.9m in Q1 2026 (Q1 2025: $(1.7)m) and related to the amortization of acquired brands and customer lists.

Adjusted Profit Before Tax¹ increased by $56.4m to $152.7m (Q1 2025: $96.3m), our strongest quarter on record, and the Adjusted Profit Before Tax Margin¹ increased to 22.1% (Q1 2025: 20.6%).

Segmental performance

Clearing

Marex provides Clearing services across the full range of commodity and financial markets. We act as principal for our clients and provide direct access to more than 60 exchanges globally.

Performance for the three months ended March 31, 2026

Clearing revenue increased by $18.0m to $137.2m (Q1 2025: $119.2m), driven by record client balances and an increase in contracts cleared, with heightened client activity throughout the quarter. Growth was further supported by new client wins and the acquisition of Aarna, which completed in Q2 2025.

Net commission income increased by $20.3m to $88.1m (Q1 2025: $67.8m), reflecting higher client activity amid very elevated volatility, particularly in Energy and Metals markets, resulting in higher volume of contracts cleared.

Net interest income increased by $19.1m to $67.5m (Q1 2025: $48.4m), reflecting higher average client balances which increased from $12.0bn in Q1 2025 to $16.0bn in Q1 2026. This increase reflected increased margin requirements amid heightened volatility, as well as continued new client onboarding which more than offset a 70 bps reduction in the average Fed Funds rate over the same period.

Net trading income decreased by $21.4m to $(18.4)m (Q1 2025: $3.0m). This includes the impact of a default from a natural gas client, recognized across both trading income ($28.2m) and credit loss provisions ($5.7m). The loss arose from an idiosyncratic event during a period of exceptional volatility. The impact of the default is partly offset by lower performance related pay in the front office and in control and support.

Despite the client loss, our strong underlying performance drove Adjusted Profit Before Tax¹ to grow 2% to $58.0m (Q1 2025: $56.6m). Adjusted Profit Before Tax Margin¹ was 42.3% (Q1 2025: 47.5%), a reduction of 520 bps reflecting the impact of the client default. Front office headcount increased to 284 (Q1 2025: 273) reflecting continued investment in geographic expansion and product capabilities.

Agency and Execution

Agency and Execution provides essential liquidity and execution services to our clients primarily in the energy and financial securities markets.

Our Securities division provides essential liquidity and risk management solutions to clients across global financial markets. Leveraging our international network, we connect buyers and sellers in equities, credit, financing, foreign exchange (FX), and rates, enabling efficient price discovery and tailored hedging strategies. Through our Prime business we also deliver comprehensive solutions for institutional clients, including clearing, custody, capital introduction, portfolio financing, and outsourced trading.

Our Energy division provides essential liquidity to clients by connecting buyers and sellers in the energy markets. We have leading positions in many of the markets we operate in, including key gas and power markets in Europe; environmental and crude markets in North America; and oil products globally. We achieve this through the breadth and depth of the services we offer to customers, including market intelligence for each product we transact in, based on the extensive knowledge and experience of our teams.

Performance for the three months ended March 31, 2026

Revenue increased by $82.8m to $322.3m (Q1 2025: $239.5m), reflecting broad-based revenue growth across our Securities and Energy businesses.

Securities revenue increased by $62.7m to $213.7m (Q1 2025: $151.0m), driven by strong performance across most of our asset classes. Growth was underpinned by Prime ($21.6m) reflecting strong client demand. Revenues also benefited from market share gains in equities, increased client activity in rates, and continued momentum in FX following the integration of Hamilton Court, including expansion in Italy and Spain and the onboarding of new clients.

Energy revenue increased by $17.5m to $105.7m (Q1 2025: $88.2m), reflecting strong growth across the business, supported by higher client activity and trading volumes. Performance in Q1 2026 benefited from weather related disruption in the US in January and heightened volatility following developments in the Middle East in March, both of which contributed to record Energy revenues for the quarter.

Adjusted Profit Before Tax<sup>1</sup> increased by $34.5m to $91.2m (Q1 2025: $56.7m), with Adjusted Profit Before Tax Margin<sup>1</sup> increasing by 460 bps to 28.3% (Q1 2025: 23.7%), reflecting increasing contribution from higher margin activities, particularly Prime. Average front office headcount increased to 876 (Q1 2025: 670), reflecting the addition of Hamilton Court alongside continued investment in new trading desks and capabilities.

Market Making

Our Market Making business provides direct liquidity to our clients across a variety of products across the Energy, Metals, Securities and Agriculture markets.

Performance for the three months ended March 31, 2026

Revenue increased by $86.7m to $139.6m (Q1 2025: $52.9m), driven by exceptional performance across our asset classes amid very elevated market volatility.

Metals revenue increased by $41.8m to $64.5m (Q1 2025: $22.7m), our best ever quarter driven by increased volatility and diversified client activity across base, precious and recycled metals markets. Market volatility resulted in wider bid-offer spreads, which created favorable trading opportunities.

Energy revenue increased by $23.4m to $32.0m (Q1 2025: $8.6m), reflecting heightened hedging activity from clients driven by price volatility linked to the conflict in the Middle East.

Securities revenue increased by $18.3m to $32.7m (Q1 2025: $14.4m), primarily reflecting the contribution from Winterflood following completion of the acquisition in December 2025.

Agriculture revenue increased by $3.2m to $10.4m (Q1 2025: $7.2m), driven by a more stable performance across the business compared with a more challenging market environment in the prior year.

Adjusted Profit Before Tax<sup>1</sup> increased by $39.0m to $55.8m (Q1 2025: $16.8m), underpinned by the significant revenue growth. Adjusted Profit Before Tax Margin<sup>1</sup> expanded by 820 bps to 40.0% (Q1 2025: 31.8%), reflecting strong operating leverage. Front office costs increased by $41.7m to $70.6m (Q1 2025: $28.9m), principally reflecting an increase in performance related pay alongside an increase in headcount primarily driven by the inclusion of Winterflood.

Corporate

Corporate manages the control and support functions of the Group and provides operational support to the business functions. In addition, Corporate manages the Group's funding requirements. Interest expense is incurred through the issuance of senior debt and structured notes which is recharged to other segments through inter-segmental funding allocations to reflect their consumption of these resources. Revenues generated in Corporate decreased in Q1 2026 from the prior period as the Group maintained surplus levels of liquidity.

Control and support costs increased from the prior year reflecting an increase in salary and discretionary pay linked to the performance of the Group, the recently completed acquisitions and continued investment across our finance, risk, technology and compliance functions as we invest in our people and systems to support the Group's future growth.

Summary Financial Position

Our balance sheet continues to consist of high-quality liquid assets which underpin client activity on our platform.

Total Assets rose from $34.7bn at December 31, 2025 to $36.5bn at March 31, 2026. This increase was largely driven by continued growth in the Group's Clearing business which resulted in a significant increase in the Group's Client Balances during Q1 2026. The growth was mainly driven by higher margin requirements due to market volatility, continued client acquisitions and increased margin balances from larger clients. This client activity was the main driver of the increase in Cash & Liquid Assets from $7.0bn to $8.6bn and the $1.8bn increase in Trade Payables to $14.8bn.

The Group's equity base increased during the three months ended March 31, 2026, with Total Equity increasing by 7% primarily driven by strong profitability in the period with Profit After Tax from Continuing Operations of $112.3m, partly offset by ordinary dividend payments of $10.8m.

| Total available liquid resources | 2991.3 | 2747.1 |
| Liquidity headroom | 1372.5 | 1045.8 |

---

A prudent approach to capital and liquidity and commitment to maintain an investment grade credit rating are core principles which underpin the successful delivery of our growth strategy. As at March 31, 2026, the Group held $3.0bn of total available liquid resources, including the undrawn portion of the committed revolving credit facility (December 31, 2025: $2.7bn).

Group liquidity resources consist of cash and high-quality liquid assets that can be quickly converted to meet immediate and short-term obligations. The resources include non-segregated cash, short-term money market funds, unencumbered securities guaranteed by the U.S. Government, excess funds held at exchanges or brokers, and other liquid unencumbered securities post haircut. The Group also includes any undrawn portion of its revolving credit facility in its total available liquid resources. The unsecured revolving credit facility of $150.0m remains undrawn as at March 31, 2026 (FY 2025: $150.0m, undrawn). Facilities held by operating subsidiaries, and which are only available to the relevant subsidiary, have been excluded from these figures as they are not available to the Group.

Liquidity headroom is based on the Group's Liquid Asset Threshold Requirement, which is prepared according to the principles of the UK Investment Firms Prudential Regime (IFPR). The requirement includes a liquidity stress impact calculated from a combination of systematic and idiosyncratic risk factors.

Regulatory capital

The Group is subject to consolidated supervision by the UK Financial Conduct Authority and has regulated subsidiaries in jurisdictions both inside and outside of the UK.

The Group is regulated as a MIFIDPRU investment firm under IFPR. The minimum capital requirement as at March 31, 2026 was determined by the Own Funds Threshold Requirement set via an assessment of the Group's capital adequacy and risk assessment conducted annually and updated after the recent acquisitions in December 2025.

The Group and its subsidiaries are in compliance with their regulatory requirements and are appropriately capitalized relative to the minimum requirements as set by the relevant competent authority. The Group maintained a capital surplus over its regulatory requirements at all times.

Maintaining a prudent approach to capital and liquidity in order to maintain an investment grade credit rating are core principles which underpin the successful delivery of our growth strategy. The Group manages its capital structure in order to comply with regulatory requirements, ensuring its capital base is more than adequate to cover the risks inherent in the business and to maximize shareholder value through the strategic deployment of capital to support the Group's growth and strategic development.

The Group performs business model assessment, business and capital forecasting, stress testing and recovery planning at least annually. The following table summarizes the Group's capital position as at March 31, 2026 and December 31, 2025:

---

| | | |
|:---|:---|:---|
| | March 31, 2026<br>$m | December 31, 2025<br>$m |

| Own Funds Threshold Requirement<sup>2</sup> | 402.6 | 402.6 |
| Total Capital Ratio<sup>3</sup> | 253% | 230% |

1. Total capital resources include unaudited results for the three months ended March 31, 2026.

2. Own Funds Requirement presented as higher of K-factor requirements and the Own Funds Threshold Requirement (OFTR) based on the latest ICARA process.

3. Total Capital Ratio expresses the Group's total capital as a percentage of Own Funds Requirement.

At March 31, 2026, the Group had a Total Capital Ratio of 253% (December 31, 2025: 230%), representing significant capital headroom to minimum requirements. The increase in the Total Capital Ratio resulted from an increase in Total Capital Resources due to profit (unaudited) in the three months ended March 31, 2026.

Dividend

The Board of Directors approved the payment of a dividend of $0.16 per share to be paid on June 3, 2026 to the shareholders on record at the close of business on May 18, 2026. &nbsp;&nbsp;&nbsp;&nbsp;

Non-IFRS Financial Measures and Key Performance Indicators

This press release contains non-IFRS financial measures, including Adjusted Profit Before Tax, Adjusted Profit Before Tax Margin, Adjusted Basic Earnings per Share, Adjusted Diluted Earnings per Share, Adjusted Profit After Tax Attributable to Common Equity and Adjusted Return on Equity. These non-IFRS financial measures are presented for supplemental informational purposes only and should not be considered a substitute for profit after tax, profit margin, return on equity or any other financial information presented in accordance with IFRS and may be different from similarly titled non-IFRS financial measures used by other companies.

Adjusted Profit Before Tax

We define Adjusted Profit Before Tax as profit after tax adjusted for (i) tax, (ii) goodwill impairment charges, (iii) acquisition costs, (iv) bargain purchase gains, (v) owner fees, (vi) amortization of acquired brands and customer lists, (vii) activities in relation to shareholders, (viii) employer tax on the vesting of Growth Shares, (ix) IPO preparation costs, (x) fair value of the cash settlement option on the Growth Shares and (xi) public offering of ordinary shares. Items (i) to (xi) are referred to as "Adjusting Items." Adjusting Items are excluded because they are not reflective of our ongoing underlying trading performance. They typically relate to acquisition accounting, shareholder-related activities and other non-recurring items, which can vary significantly between periods and are not considered part of the Group's core operations.

Adjusted Profit Before Tax is the primary measure used by our management to evaluate and understand our underlying operations and business trends, forecast future results and determine future capital investment allocations. Adjusted Profit Before Tax is the measure used by our executive board to assess the financial performance of our business in relation to our trading performance. The most directly comparable IFRS Accounting Standards measure is profit after tax.

We believe Adjusted Profit Before Tax is a useful measure as it allows management to monitor our ongoing core operations and provides useful information to investors and analysts regarding the net results of the business. The core operations represent the primary trading operations of the business.

Adjusted Profit Before Tax Margin

We define Adjusted Profit Before Tax Margin as Adjusted Profit Before Tax (as defined above) divided by revenue. We believe that Adjusted Profit Before Tax Margin is a useful measure as it allows management to assess the profitability of our business in relation to revenue.

IFRS accounting standards do not define profit margin. Therefore the most directly comparable IFRS measure for profit margin is Profit After Tax divided by revenue.

Adjusted Profit After Tax Attributable to Common Equity

We define Adjusted Profit After Tax Attributable to Common Equity as profit after tax adjusted for the items outlined in the Adjusted Profit Before Tax paragraph above. Additionally, Adjusted Profit After Tax Attributable to Common Equity is also adjusted for (i) tax and the tax effect of the Adjusting Items to calculate Adjusted Profit Before Tax and (ii) profit attributable to AT1 note holders, which is the coupons on the AT1 issuance and accounted for as dividends, adjusted for the tax benefit of the coupons, and (iii) profit attributable to non-controlling interest.

We define Common Equity as being the equity belonging to the holders of the Group's share capital. We believe Adjusted Profit After Tax Attributable to Common Equity is a useful measure as it allows management to assess the profitability of the equity belonging to the holders of the Group's share capital.

The most directly comparable IFRS Accounting Standards measure is profit after tax.

Adjusted Return on Equity

We define the Adjusted Return on Equity as the Adjusted Profit After Tax Attributable to Common Equity (as defined above) divided by the average Common Equity for the period.

Common Equity is defined as being the equity belonging to the holders of the Group's share capital. Average Common Equity for the three months ended March 31, 2026 and March 31, 2025 is calculated as the average of Common Equity as at 31 December of the prior period and 31 March of the current period. For the three months ended March 31, 2026 and March 31, 2025, Adjusted Return on Equity is calculated for comparison purposes on an annualized basis as Adjusted Profit After Tax Attributable to Common Equity for the period multiplied by four and then divided by average Common Equity for the period. It is presented on an annualized basis for comparison purposes. We believe Adjusted Return on Equity is a useful measure as it allows management to assess the return on the equity belonging to the holders of the Group's share capital.

The most directly comparable IFRS Accounting Standards measure for Adjusted Return on Equity is Return on Equity, which is calculated as profit after tax for the period divided by average equity. Average equity is calculated as the average of total equity as at 31 December of the prior year and 31 March of the current year.

Adjusted Basic Earnings per Share and Adjusted Diluted Earnings per Share

Adjusted Basic Earnings per Share is defined as the Adjusted Profit After Tax Attributable to Common Equity for the period divided by the weighted average number of ordinary shares for the period. We believe Adjusted Basic Earnings per Share is a useful measure as it allows management to assess the profitability of our business per share. The most directly comparable IFRS Accounting Standards metric is Basic Earnings per Share. This metric has been designed to highlight the Adjusted Profit After Tax Attributable to Common Equity over the available share capital of the Group.

Adjusted Diluted Earnings per Share is defined as the Adjusted Profit After Tax Attributable to Common Equity for the period divided by the diluted weighted average shares for the period. We believe Adjusted Diluted Earnings per Share is a useful measure as it allows management to assess the profitability of our business per share on a diluted basis. Dilution is calculated in the same way as it has been for Diluted Earnings per Share. The most directly comparable IFRS Accounting Standards metric is Diluted Earnings per Share.

Non-IFRS Financial Measures and Key Performance Indicators continued

We believe that these non-IFRS financial measures provide useful information to both management and investors by excluding certain items that management believes are not indicative of our ongoing operations. Our management uses these non-IFRS financial measures to evaluate our business strategies and to facilitate operating performance comparisons from period to period. We believe that these non-IFRS financial measures provide useful information to investors because they improve the comparability of our financial results between periods and provide for greater transparency of key measures used to evaluate our performance. In addition these non-IFRS financial measures are frequently used by securities analysts, investors and other interested parties in their evaluation of companies comparable to us, many of which present related performance measures when reporting their results.

These non-IFRS financial measures are used by different companies for differing purposes and are often calculated in different ways that reflect the circumstances of those companies. In addition, certain judgments and estimates are inherent in our process to calculate such non-IFRS financial measures. You should exercise caution in comparing these non-IFRS financial measures as reported by other companies.

These non-IFRS financial measures have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under IFRS Accounting Standards. Some of these limitations are:

• they do not reflect costs incurred in relation to the acquisitions that we have undertaken;

• they do not reflect impairment of goodwill;

• other companies in our industry may calculate these measures differently than we do, limiting their usefulness as comparative measures; and

• the adjustments made in calculating these non-IFRS measures are those that management considers to be not representative of our core operations and, therefore, are subjective in nature.

Accordingly, prospective investors should not place undue reliance on these non-IFRS financial measures.

Key Performance Indicators

We also use key performance indicators ("KPIs") such as Average Balances and Contracts Cleared to assess the performance of our business and believe that these KPIs provide useful information to both management and investors by showing the growth of our business across the periods presented.

Our management uses these KPIs to evaluate our business strategies and to facilitate operating performance comparisons from period to period. We define certain terms used in this release as follows:

"FTE" means the number of our full-time equivalents as of the end of a given period, which includes permanent employees and contractors.

"Average FTE" means the average number of our full-time equivalents over the period, including permanent employees and contractors.

"Average Balances" means the average of the daily holdings in exchanges, banks and other investments over the period. Previously, average balances were calculated as the average month end amount of segregated and non-segregated client balances that generated interest income over a given period.

"Total Capital Ratio" means our total capital resources in a given period divided by the capital requirement for such period under the IFPR.

"Contracts Cleared" means the total number of contracts cleared in a given period.

"Volumes" means the volume of exchange traded derivatives transacted in a given period.

Clearing Market Volumes are calculated as futures and options traded and/or cleared on Marex key exchanges (CBOT, CME, Eurex, Euronext, ICE, LME, NYMEX, COMEX, SGX).
