StoneX | Annual Report 2024 8 In a year that tested the resilience of financial companies globally, StoneX delivered exceptional results, achieving revenue targets and demonstrating the strength of our evolving business model. Despite declining volatility and interest rates, which typically pose challenges for StoneX, we have grown our trading volumes and achieved in excess of our 15% ROE target by attracting new clients, effectively managing costs and expanding our product and geographical range. This adaptability, irrespective of market conditions, reflects the fundamental strength of our business model that has guided us to achieve a 32% revenue CAGR for the last 21 years. Chairman’s letter StoneX’s success is also reflected in our strong stock market performance, which shows recognition by the investment community of our continuing growth and increasing importance in the financial services industry. The value proposition is clear: our stock rose nearly 27% year-over-year, while still trading at less than half the earnings multiple of the S&P 500 (a 13.03 PE ratio vs 30.52). Our performance underscores the significant potential for value creation, as more investors recognize our consistent execution and growing market presence as a leading financial services franchise. The financial markets are undergoing fundamental structural changes which create significant opportunities for StoneX. Regulatory requirements, including the Basel regime, have imposed stricter capital constraints on the trading activities of larger banks and raised regulatory costs for smaller players, forcing many out of the market. StoneX is uniquely positioned to capitalize on these changes, leveraging this environment to onboard a record number of Commercial/ Institutional clients in Q3 2024. Simultaneously, the rise of off-exchange trading is reshaping public markets. Major financial platforms have been increasingly executing trades internally, reducing reliance on public exchanges. This model enhances efficiency, lowers transaction costs, and improves control over trading processes. With our strategic focus on internalization, StoneX is extremely well- positioned to be a key player in this evolving financial ecosystem, laying the groundwork for future growth. Our internalization strategy is proving particularly transformative for the business - by designing our trading platforms to aggregate trading and internalize spreads, we’ve created a virtuous cycle: best pricing for clients, reduced hedging costs for our business, and maximized revenue opportunities as spreads are internal. Our diverse product and geographical base make internalization possible, raising the probability of offsetting trades and driving substantial revenue capture and margin increase. 8

9 Strategy Governance Financial StatementsAppendixOverview As a business, we have established comprehensive capabilities across every aspect of a financial transaction – from execution to clearance and settlement while creating natural spreads and hedges through our product diversity. Our total addressable market (TAM) is enormous and presents an extraordinary growth opportunity; currently, we are leaving ample room to develop across all our business units. I’d like to also highlight one of our business units that significantly outperformed this year. Our acquisition of Gain Capital Holdings, Inc. has evolved to become a cornerstone of our growth strategy, delivering a 19% increase in Self-Directed/Retail segment operating revenues year-over-year despite less than favorable market conditions. The acquisition has exceeded our expectations as we benefited significantly from both internalization of spreads and product diversification. But we must be mindful of ongoing macroeconomic challenges. As our company has grown to over 70 offices and 4,500+ employees, we cannot simply keep our nose to the grindstone and ignore the broader market impacts. Interest rates, volatility, and upcoming electoral changes add uncertainty to our business at every turn. The ever-growing U.S. deficit and elevated stock market valuations relative to U.S. GDP warrant careful consideration. I remain confident in our disciplined approach to market exposure, and applaud our risk controls during critical moments, such as the unprecedented volatility in cocoa futures prices earlier this year. The financial markets are undergoing fundamental structural changes which create significant opportunities for StoneX. 9

StoneX | Annual Report 2024 10 John Radziwill Chairman I am grateful to our employees for their contributions, and to our shareholders for their trust and support. As StoneX transitions into a major financial franchise, the preservation of our company’s culture remains a fundamental priority. Our power lies in our people, and our culture serves as a key differentiator that builds our client relationships and fosters long-term trust. The exceptional talent of our internal teams is a major driver of our success. Hand in hand with our culture are the exceptional people who have driven the company forward. Sean O’Connor is the best example of this and one of his major achievements has been the establishment of a strong management team. Therefore, it is with great pride that we are able to internally appoint a new Chief Executive Officer, Philip Smith, and President, Charles Lyon, to take primary responsibility for the day-to- day running of the company. They will report to Sean, who is appointed Executive Vice Chairman and will continue to be an active member of StoneX’s executive committee with a primary focus on longer-term strategy, capital allocation and M&A activity. On a personal note, Sean and I have attended approximately 90 board meetings since 2003, and the remarkable progress of the company under his leadership, from a market value of approximately $5 million to over $3.0 billion today, is both incredible and impressive. I am confident that the new management structure will ensure the continuation of this trajectory. Our strategy going forward will continue to be anchored by our key company objectives: building our ecosystem, growing and diversifying our client base, digitizing our business, compounding capital, and increasing internalization of our product flows. These strategic objectives have proven effective time and time again as we maintain a strong ROE on an expanding capital base. Despite the numerous investments made this year in technology and infrastructure, the cost of developing new capabilities, and the integration of numerous acquisitions, we have exceeded our revenue targets. We’ve deployed our increasing capital with efficiency, achieving growth with minimal share dilution and maintaining strict discipline in our acquisition strategy. When potential opportunities don’t meet our criteria, we maintain the restraint to step away – a principle that has served us well over the years. In closing, I believe that our combination of a client-first mentality, strategic diversification and advancing digital capabilities will continue to differentiate us in the financial marketplace in 2025.

StoneX | Annual Report 2024 12 Shareholder equity $1,709.1 | CAGR 28% Market value $2,609.9 | CAGR 29% Operating revenue $3,436.2 | CAGR 32% Our track record 2002 - 2024 (in USD mm) StoneX has achieved a strong compound annual growth rate (CAGR), driven by strategic expansion across asset classes and increased market share in equities, commodities, foreign exchange, and fixed income. This consistent growth highlights StoneX’s ability to adapt to client needs and capitalize on market opportunities, reinforcing its position as a resilient and integrated global financial services provider. Chief Executive’s letter Introduction As we reflect on a milestone year at StoneX, I want to extend my gratitude for your confidence and continued support. Fiscal Year 2024 was marked by the highest earnings and operating revenues in our history—achievements made even more significant as they were accomplished despite diminished volatility and an overall challenging market environment. These results underscore the strength of our business model, the dedication of our employees, and the trust of our clients. As we celebrate our centennial year, we are also laying the groundwork for future success. With strategic realignments to our offerings, we are positioning StoneX to thrive and continue to deliver exceptional value to our shareholders.

13 Overview Strategy Governance Financial StatementsAppendixt Record financial performance Fiscal 2024 was a record year for StoneX, with operating revenues reaching $3.4 billion, an 18% increase from the prior year, driven by strong client activity and increased volumes across nearly all segments. Net income grew 9% to a record $260.8 million, and diluted earnings per share (EPS) rose 7% to $7.96. Our return on equity (ROE) of 16.9% exceeded our 15% target, reflecting our disciplined capital allocation and resilient approach to challenging market environments. These results, capped by a very strong fourth quarter, underscore our success in deepening client engagement and expanding market penetration and provide solid momentum as we enter Fiscal 2025. As proud as we are of these results, we believe the true measure of our approach’s success lies in our long-term performance. Over the past 21 years, we have grown stockholder equity, operating revenue, and market capitalization at nearly 30% compound annual growth rates. This track record, which we believe is unmatched in the industry, enables us to continue delivering sustained value regardless of market conditions.

StoneX | Annual Report 2024 14 Over the past 21 years, we have grown stockholder equity, operating revenue, and market capitalization at a nearly 30% compound annual growth rate. Our continued financial performance is powered by four drivers: market opportunities and industry consolidation that enable us to expand our client footprint and grow volumes over time, market volatility which drives our revenue capture, the impact of interest rates on our client float, and finally, our ability to control costs and drive operational leverage. The market environment remains favorable for client acquisition, with larger banks increasingly focused on servicing only their biggest clients as capital pressures from Basel III mount. Meanwhile, consolidation continues at the lower end of the market. Together, these trends create meaningful opportunities for expansion in our addressable market, a dynamic which I expect will continue for some time. In this environment where the market structure is changing and being reformatted, our comprehensive financial ecosystem becomes a key determinate for winning new clients. Our unique ability to provide efficient execution, as well as post-trade clearing, custody and financing services across all asset classes make us a financial counterparty of choice for these clients. This is validated by record levels of client onboarding, including an all-time high in the third quarter, as well as increased cross-selling revenue as our clients leverage our unique and growing ecosystem. Our success in this regard is best demonstrated by client volumes across our various products. As shown in the table below, we increased volumes across nearly all our products, an even more impressive result given the reduced volatility environment. Listed derivatives and securities were standout performers, with volumes up 34% and 36%, respectively. The lower volatility impacted revenue capture across nearly all of our products with the exception of FX/CFDs which saw a 32% increase. We are committed to delivering ‘best execution’ for our clients across all our products, which means we primarily operate as a ‘price taker’ in terms of revenue capture the market affords to us. This lower volatility environment reduced our revenue capture from 5-15% compared to the prior year, significantly offsetting the positive impact of client volume increases. In many markets though, volatility seems to have reached its lowest points and we are unlikely to see further erosion in revenue capture. Going forward, volume growth should now translate more linearly into revenue growth for each of our products. Of course, any increase in revenue capture due to heightened volatility would further amplify the impact of greater client volumes on revenue realized. Since the onset of the COVID-19 pandemic, interest has been a tailwind for our business, driven not only by the Federal Reserve’s rate hikes but also by a substantial growth in client float. Over the last three years, our expanded client base and higher margin requirements, driven by increased market volatility, have led to this expansion. We have now seen this cycle peak, and although our interest and fees earned on client balances still increased 12% over the prior year, we now face headwinds from declining interest rates and lower margin requirements due to suppressed volatility. Fortunately, the majority of our float earns a net interest margin which is unaffected by lower interest rates – unless we return to zero rates, which I view as highly unlikely. The impact of reduced rates may be further offset as the rate trajectory now appears flatter than initially anticipated, and the ongoing growth of our client base can result in increased client float. 14

15 Overview Strategy Governance Financial StatementsAppendixt 15 Our significant growth and product expansion over the last three years have led to higher operational costs. Additionally, as we continue to digitize our business, we have made substantial investments in technology and talent, resulting in costs that are incurred ahead of revenue. Consequently, expenses have increased nearly in line with net revenue, with limited operational leverage realized. Overall, costs increased by 8% for the year, which is considerably lower than in the previous two years and slightly below the 9% growth rate of our net operating revenues. We believe our overall costs, including investments, should moderate as a percentage of revenue, assuming all else remains equal. We have heightened our focus on cost management and ensuring that our infrastructure is more digital and scalable to drive operational leverage and margin expansion as we continue to grow revenues. We expect to see tangible benefits from our technology investments, which will fuel revenue growth, create operational scalability, and ultimately drive margins.

StoneX | Annual Report 2024 16 1 Progress on our strategic initiatives At StoneX, we continue to employ the same fundamental strategy that has remained as relevant today as it was 20 years ago. At StoneX, our ecosystem is the foundation for long-term growth. By integrating a diverse suite of products, services, and advanced technologies, we connect clients to global financial markets, providing seamless access to essential tools and solutions. Our strategy focuses on delivering scalable, innovative, and client-focused solutions, backed by investments in talent and technology to continually enhance our capabilities. These investments, though incurring upfront costs, are crucial for building long-term value and expanding our market reach. As our ecosystem grows, we expect to achieve operational leverage, improve margins, and strengthen our position as a leading financial services provider. By staying committed to focused execution, we ensure that every action we take is aligned with our core goals and delivers measurable impact. Our approach to innovation keeps us at the forefront of industry advancements, while client-centricity drives us to consistently meet and exceed the evolving needs of those we serve. Ecosystem optimization 2 3 StoneX is client-centric, focused on expanding our footprint into new markets and increasing market share with existing clients. We aim to serve new segments and channels, leveraging our capabilities to tap into a large, underpenetrated market, while enhancing our ecosystem to strengthen our value proposition for both new and existing clients. Over the past decade, we have significantly expanded our client footprint, aided by a favorable industry environment. We believe that our unique global financial ecosystem positions us to be the counterparty of choice, placing us in a strong position to capture market share. In 2024, we leveraged our extensive marketing assets, particularly in digital, to aggressively grow the StoneX brand and enhance market visibility. Central to our strategy is building a comprehensive financial ecosystem that meets the diverse needs of our clients, with cross-selling becoming deeply embedded in our culture and actively tracked. This approach has proven successful, as evidenced by the sustained high level of new account onboarding, culminating in an all-time quarterly record in Q3, which highlights our ability to continually attract and serve new clients. We continue to strengthen our global presence with strategic investments in key markets. In the EU, we’ve expanded our Frankfurt office post-Brexit, enabling us to better serve our existing clients while reaching new ones who may be underserved in the current environment. Alongside this, we’ve enhanced our regulatory standing in Germany with a full BaFin license and an upgraded EEX membership. In Asia, we’ve expanded our product capabilities in Singapore, adding expertise in fixed income, prime services and clearing, foreign exchange, and commodities, which positions us for deeper market penetration in the region. These efforts, along with the broadening of our licensing to support a wider range of payments and securities offerings, are gaining momentum in an underrepresented yet highly promising market. Market expansion

17 Overview Strategy Governance Financial StatementsAppendixt Finally, our business is underpinned by capital, and we need to support our growth with internally generated capital, accessing capital markets when appropriate, and approach acquisitions in a disciplined manner. We prioritize ROE and capital compounding as key metrics of success. Over the past decade, we have more than tripled our shareholders’ funds, acquired over 15 businesses, and expanded our client footprint, largely financed through retained earnings and the power of compounding. Achieving our ROE target remains a critical goal, and as we continue to digitize our platform and scale our operations, we expect improvements in both margins and ROE. Our strategy also involves selectively engaging with capital markets, ensuring any additional capital raised is appropriately priced. This was demonstrated by our successful refinancing of senior secured notes from the GAIN acquisition, where we upsized the deal from $350 million to $550 million and extended the duration of our capital stack at a significantly lower yield spread. This approach strengthens our financial position and supports long- term growth. Compounding capital 3 4StoneX is actively embracing digitization to drive growth, scalability, and efficiency across its operations. By leveraging technology, we are enhancing client engagement, expanding our addressable market, and improving margin expansion. Our trading platforms are increasingly digital, allowing us to aggregate trades, internalize spreads, and improve revenue capture, particularly in our self-directed/retail business. We have made significant strides in risk management through real- time data aggregation and monitoring, which strengthens our ability to manage risk across the organization. A major focus is to make it easier for clients to start doing business with us by streamlining onboarding and monitoring processes through a global technology solution that simplifies workflows, harmonizes data, and provides self-service options. This initiative is already underway and is expected to significantly enhance operational efficiency. Additionally, we’re focusing on using ‘best cost locations’ for support, allowing us to manage costs more effectively. To further enhance scalability, we’ve developed a centralized data lake to integrate client and transactional data, and introduced a global StoneX ID for seamless data matching. Looking ahead, we plan to centralize all market data into a hub, dramatically reducing data costs. These initiatives collectively position StoneX to achieve greater digital transformation, expanding our capabilities and improving margins as we scale globally. Digital transformation

19 Overview Strategy Governance Financial StatementsAppendixt Commercial Our commercial segment reported operating revenues of $871.9 million, roughly in line with Fiscal Year 2023. Stronger results from listed derivatives, up 14% year-over-year, and interest income were offset by lower revenues from OTC derivatives and physical commodities. 2024 marked significant expansion in the commercial segment overall. In January, StoneX became Abaxx Exchange’s first clearing and trading member, providing clients access to physically deliverable futures contracts for LNG, nickel sulphate, and carbon. We also joined the Montreal Exchange (TMX), expanding our expertise in listed products including fixed income. Additionally, we continue to evaluate other potential trading venues to expand our capabilities and better serve our clients. In October, StoneX Metals Limited completed its acquisition of JBR’s precious metal recovery and refinery business, strengthening our market-leading metals offering by integrating a key part of the supply chain and addressing growing global demand for recycled silver. The newly established StoneX Specialty Coffee team brings decades of green coffee expertise and a powerful network spanning over 20 countries, further enhancing our commercial capabilities. Our electronic metals trading platform, PMX, has become a market-leading execution venue, achieving a record daily notional trading volume of over $3.6 billion. We are also very active on Bloomberg FXGO, where we were ranked #1 overall for all metals-related products. Our StoneHedge offering has achieved critical mass and is now the go-to solution for large grain elevators in the Midwest. This platform has doubled its volumes for the third straight year, now with over 620 locations and 900 traders. It is a prime example of using technology to add value to our large commercial clients and embed ourselves as a long-term partner in their business. We are now looking to expand this offering to include other commodity products and more jurisdictions. We have expanded our capabilities in physical commodities to provide comprehensive services, including risk management and logistics. Our acquisition of CDI, a physical cotton brokerage business based in Brazil and Switzerland, has almost doubled its gross revenues in its first year, validating the integration of hedging services with the sale of physical commodities and related logistics. We are now offering this bundled service to coffee producers in Brazil, with promising early results, and plan to expand this approach to other products and regions. During the year, we established an office in GIFT City in Gujarat, India, to facilitate trading of precious metals into the strategically important Indian market. We also became the first international trading and self-clearing entity on the local Indian International Bullion Exchange (IIBX), positioning ourselves for broader access to other products and capabilities across the subcontinent. 19

StoneX | Annual Report 2024 20 Institutional Our institutional segment delivered strong results in Fiscal Year 2024, with operating revenues rising 30% year-over-year to $1,962 million. This growth was driven by strong performance in equity market- making, derivatives, and interest income. In equities, we expanded our electronic market-making platform for domestic NMS equities, achieving a record 118 billion shares traded. Key drivers of our global growth include StoneX’s network of localized expertise and a comprehensive trading and execution platform, enabling us to expand into new markets while strengthening our presence in existing ones. Notably, StoneX Financial Pty Ltd became a direct clearing and trading member of the Australian Securities Exchange (ASX), granting clients access to the Australian derivatives market, while StoneX Financial (Canada) Inc. achieved Approved Participant status on the Montreal Exchange (TMX), expanding access to institutional-grade products globally. Our prime services offering, essential for hedge funds, has evolved into a global multi-asset execution and custody platform, supporting activity across all segments. In 2024, we expanded our reach in the UK with repo financing and securities lending, while continuing to invest in technology for trading, regulatory reporting, and back-office operations. The global prime business grew by more than 20%, fueled in part by growth in the ETF space, where we provide tailored custody and execution solutions. Our outsourced services business, which has become a core part of our prime offerings, continues to grow and has received industry recognition, including awards for Best Outsourced Solution from Hedge Fund Magazine and HedgeWeek. Additionally, we expanded into credit and sell-side outsourced trading, introducing two new approaches to the industry. To strengthen our presence in the emerging regulated crypto market, we made key hires for StoneX Digital in the U.S. and established the infrastructure to become a digital asset custodian in Ireland, where we have received regulatory approval. Similarly, we continue to make progress in the growing carbon trading market, with an expanding client base and revenue stream. Our fixed income offering continues to expand, broadening both our credit capabilities and global reach. As part of this growth, we recently announced our intention to acquire Octo Finances, a leading fixed-income trading firm based in Paris, pending regulatory approval. This acquisition will enhance our offerings in bonds, convertible securities, and credit research while providing greater access to the EU institutional market. Additionally, we are leveraging technological advancements to deliver resilient, low-latency solutions that address the evolving needs of institutional clients and developing innovative platforms like LoanMatch, designed to bring greater transparency and liquidity to the loan market.

21 Overview Strategy Governance Financial StatementsAppendixt Self-Directed/Retail Our self-directed segment delivered exceptional results in 2024, with operating revenues increasing 19% to $395.0 million and segment income rising by 160%, reflecting the operational leverage in our self-directed platforms. Even with challenging market conditions, lower trading volumes were offset by record-breaking new client acquisition, improved revenue capture, better internalization of spreads, and product diversification, resulting in operating revenue rising 19%, further emphasizing the strength of this segment. We evolved our retail segment to “self-directed” with the goal of integrating the full suite of StoneX products and services into our retail digital platform. This initiative, powered by our digital marketing team, will expand our addressable market for StoneX products globally. The self-directed platform enables us to offer a curated set of products to clients, allowing for efficient digital marketing, onboarding, servicing, and trade execution. We’ve made meaningful progress on this multi-year project, already delivering impactful results. Our flagship FOREX.com platform reinforced its position as the number one forex broker in the U.S. through an innovative partnership with Kalshi, a CFTC-regulated exchange. This collaboration allows trading on the outcome of future events, further enhancing our technology-driven solutions for self- directed clients. On the agricultural side, StoneX Plus has gained momentum, reaching over 300 active clients, including many large enough for high-touch relationships. With a proven, scalable product, we can now digitally market to hundreds of thousands of farmers globally, providing risk management advice and hedging capabilities without the constraints of traditional high-touch models. 21

StoneX | Annual Report 2024 22 1 22 Payments The payments business remained relatively flat in 2024, with operating revenues of $209.6 million reflecting the impact of tighter FX spreads in key payment corridors. Despite challenging market conditions, we made a significant investment to enhance our infrastructure in order to better serve an expanding network of banks and financial institutions. We are finalizing the rework of our global payments system architecture, with most clients migrated to our new cloud-based system, delivering significantly higher STP rates on payments. Our internally built XPay system enables payments-at-scale and eliminates costly vendor-based solutions, improving efficiency, scalability, and the ability to meet diverse client needs globally. These upgrades provide secure, reliable, and real-time payment capabilities, strengthening our position as a trusted partner in the global payments ecosystem. Additionally, StoneX was one of the first financial organizations to enable Swift’s new pre-validation service for cross-border payments, enhancing transaction speed and improving straight-through- processing for a more seamless client experience.

23 Overview Strategy Governance Financial StatementsAppendix 1 2 3 Our commitment to ESG We are actively measuring and seeking ways to reduce our environmental footprint. From improving energy efficiency across our offices to exploring sustainable procurement practices, we are committed to minimizing our impact on the planet while aligning with global efforts to address climate change. At StoneX, we recognize that our people are our greatest asset. We are dedicated to fostering a diverse and inclusive workplace, where every employee feels valued and empowered. This commitment extends to supporting the communities we serve, through philanthropic efforts, financial literacy initiatives, and partnerships that drive positive social impact.

StoneX | Annual Report 2024 2424 2025 Outlook Looking ahead, we are well-positioned to capitalize on the ongoing industry transformation driven by regulatory changes and market consolidation. These shifts not only create significant opportunities for StoneX to expand its market share but also provide a substantial runway for growth. Our ecosystem, underpinned by broad capabilities and diverse offerings, enables us to deliver innovative solutions that simplify client operations, expand their market reach, and create long-term value. Central to our strategy is the disciplined use of capital, supported by our ‘fortress balance sheet’. Over the past decade, we have tripled shareholder funds, acquired more than 15 businesses, and expanded our client footprint, primarily financed organically through retained earnings and the remarkable power of compounding. We anticipate our recent acquisitions, combined with selective access to capital markets, will continue to drive meaningful growth and further strengthen our position in the market. The evolving regulatory landscape, shifting market dynamics, and our increasingly recognized ecosystem—along with the prospect of improved market volatility despite declining interest rates—still provide a favorable tailwind for our business. As we continue to move forward, we remain committed to expanding our client base in both new and existing markets, while deepening client relationships through effective cross-selling strategies. In summary, we believe that our growth strategy is underpinned by the following: Constructive market dynamics that will enable us to capture market share from larger banks Leveraging our geographic footprint to expand into markets where we are underrepresented Adding new product and services to our ecosystem (white space) to create new revenue streams Cross-selling our expanding ecosystem of products and services to our growing client base Scaling our self-directed offering to broaden our addressable market, and overcoming the limitations of our high- touch approach and geographic reach

25 Overview Strategy Governance Financial StatementsAppendixt Over the past decade, we have tripled shareholder funds, acquired more than 15 businesses, and significantly expanded our client footprint. Thank you for being part of the StoneX journey. It has been 22 years since I founded StoneX and became CEO. From humble beginnings—just 10 people and less than $10 million in equity—we have grown into a thriving financial franchise with over 4,500 employees and over $3 billion in revenue and market value. This remarkable achievement is a testament to the incredible team at StoneX, whose hard work has made this journey possible and provided me with an experience beyond my wildest dreams. Leading this company has been an enormous privilege, and one for which I am deeply grateful. However, it has become time to transition of management to the next generation of exceptionally capable leaders. As such, I am thrilled that Philip Smith and Charles Lyon have taken on the day-to-day leadership of StoneX as CEO andPresident, respectively. I have transitioned to the role of Executive Vice Chairman, remaining a full-time employee and member of the executive committee with a focus on longer-term strategy, capital allocation and M&A activity, Philip, Charles, andI have worked together for over 20 years, and I have complete confidence in their ability to build on our track record of success. On behalf of the executive team, I want to thank our clients, employees, and shareholders for their unwavering support. As we mark the 100th anniversary of Saul Stone & Company, we honor the entrepreneurial spirit that laid the foundation for the company we are today. With a strong legacy and a clear vision for the future, StoneX is ready to seize emerging opportunities as a leading global financial franchise. Closing remarks Sean O’Connor Chief Executive Officer

44 StoneX | Annual Report 2024 Corporate governance statement The Company is committed to high standards of corporate governance and has put in place a framework that fosters good governance, is practical for a company of our size and satisfies our current listing and regulatory requirements. The Company has instituted a Code of Ethics that demands honest and ethical conduct from all employees. Specific topics covered are conflicts of interest, fair dealing, compliance with regulations, and accurate financial reporting. Board of Directors The Company has a Board of Directors consisting of one executive and seven independent directors. The Chairman is a non-executive director. The Board oversees the strategy, finances, operations and regulatory compliance of the Company through regular quarterly meetings and additional special meetings when required. The non-executive directors regularly meet independently of the executive director. The Nominating & Governance, Audit, Compensation, Risk, and Technology and Operations Committees are each composed of at least three independent Directors. The Audit Committee meets the SEC requirement that at least one of its members should be a financial expert. Board independence We are committed to maintaining the independence of our board as it relates to applicable rules and industry best practices because we believe doing so serves the best interests of our shareholders. No Director is considered independent if he or she is an executive officer or employee of the Company or has a relationship which, in the opinion of the Company’s Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a Director. In its annual review based on this criteria (in line with Rule 5600 of the NASDAQ Stock Exchange), the Nominating & Governance Committee of the Board determined that each of our directors qualifies as independent, with the exception of Sean O’Connor, the Company’s Executive Vice-Chairman of the Board of Directors. Executive structure The roles of Chairman and CEO are split in accordance with widely recognized best practices with regard to maintaining board independence. John Radziwill serves as the Company’s Chairman. The CEO and CFO make all necessary representations to satisfy regulatory and listing requirements. Executive compensation is determined by a Compensation Committee composed exclusively of independent directors. Executive pay tied to performance The pay for the members of our executive committee is closely tied to the financial performance of the Company. Specifically, the annual cash bonus for each executive is based entirely on the Company’s return on equity, a metric that is considered to be closely linked to stock price appreciation. A substantial portion of the annual cash bonus – generally 30% – is paid in the form of restricted company stock, which is purchased at a discount but vests over a three-year period. In addition, executives receive long-term cash awards, which generally vest five years following grant, and their growth in value is also tied to the Company’s return on equity. Executive compensation information can be found in our filings with the SEC on Form DEF 14A -Other definitive proxy statements.

45 Overview Strategy Governance Financial StatementsAppendix Forward-looking statements This Annual Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These forward-looking statements involve known and unknown risks and uncertainties, including the risks and uncertainties described in the Company’s Annual Report on Form 10-K and other filings with the Securities and Exchange Commission, many of which are beyond the Company’s control. These risks and uncertainties include adverse changes in economic, political and market conditions, losses from the Company’s activities arising from customer or counterparty failures, changes in market conditions, the possible loss of key personnel, the impact of increasing competition, the impact of changes in government regulation, the possibility of liabilities arising from violations of laws or regulations and the impact of changes in technology on our businesses. Although the Company believes that its forward-looking statements are based upon reasonable assumptions regarding its businesses and future market conditions, there can be no assurances that the Company’s actual results will not differ materially from any results expressed or implied by the Company’s forward-looking statements. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Readers are cautioned that any forward-looking statements are not guarantees of future performance. Financial interest requirements for directors and CEO We require directors and our CEO to own a substantial equity stake in company stock. This requirement has been based on a meaningful percentage of the director’s or CEO’s most recent year’s cash compensation and we now require our directors and CEO to own an amount of company stock equal in value to three times their annual cash compensation, subject to a phase-in period for new directors. Financial reporting and internal control The Company strives to present clear, accurate and timely financial statements. Management has a system of internal controls in place, regularly assesses the effectiveness of these controls and modifies them as necessary. Risk management is an important aspect of this system of internal controls, and the Risk Committee monitors compliance with risk policies. Investor relations The Company seeks to provide accurate and timely information to stockholders and other stakeholders to facilitate a better understanding of the Company and its activities. The Company seeks to distribute such information as widely as possible through filings on Form 8-K, press releases and postings on its website, www.stonex.com.

50 StoneX | Annual Report 2024 The table below presents net income as reported in accordance with Generally Accepted Accounting Principles (“GAAP”). The table below also presents a reconciliation to adjusted net income and adjusted ROE, which are non-GAAP measures. The adjusted non-GAAP amounts reflect each item after removing the impact of the gains on acquisitions and related transaction costs and other expenses for the years ended September 30, 2024, 2023, 2022, 2021 and 2020. Management believes that presenting our results excluding the gains on acquisitions and related transaction costs and other expenses is meaningful, as it increases the comparability of period-to-period results.
