IBKR BestXTM Maximize Execution Quality, Minimize Market Impact. IBKR BestXTM is a powerful suite of advanced trading technologies designed to help clients achieve best execution and maximize price improvement while minimizing market impact and maintaining complete control over their orders. For IBKR Pro clients, Interactive Brokers does not sell its customer order ﬂow to high frequency traders. Orders are routed by IBKR directly to one or more execution venues, including multiple exchanges, dark pools, and IBKR’s own alternative trading system (ATS). IBKR BestX’s suite of choices offers clients a powerful solution for helping to achieve best execution and price improvement across their trading activities by combining (depending on the product being traded) the IBUSOPT destination, the IBKR ATS, advanced order types, and IB SmartRoutingSM. IBUSOPT IB SmartRoutingSM For US listed equity options and certain index options, the IBUSOPT destination is designed to offer clients the opportunity to interact with IB SmartRouted marketable order ﬂow and have their orders ﬁlled between the National Best Bid/Offer (NBBO). Clients can buy between the bid and the midpoint or sell between the offer and the midpoint without revealing their trading interests to the market or being subject to adverse selection by market-moving orders. IBKR ATS For US listed stocks and ETFs, the IBKR ATS allows IBKR Pro clients to choose to interact solely with IB SmartRouted order ﬂow and access order ﬂows that may not be available at exchanges. This helps to provide price improvement on large volume and block orders while minimizing market impact. For IBKR Pro clients, IB SmartRoutingSM is designed to provide best execution by continuously searching for the best available prices for stocks, options, and combinations across exchanges and dark pools. This technology dynamically re-routes all or part of clients’ orders to achieve immediate electronic execution, while factoring in transaction costs, fees, rebates, and other factors that impact trade execution. Advanced Order Types and Algorithms IBUSOPT and IBKR ATS offer proprietary order types designed to help clients maximize price improvement. For additional information, see ibkr.com/options Options involve risk and are not suitable for all investors. For more information read the “Characteristics and Risks of Standardized Options” by visiting ibkr.com/occ Securities Lending Dashboard Clients can now access the same expanded securities lending data and key metrics for US equities that previously were only available to banks, broker-dealers and large institutional investors.

Barron’s is a registered trademark of Dow Jones & Co. Inc. See ibkr.com/awards March 1, 2024 Dear Shareholders, Another year, another new record, for number of clients, customer equity, revenues and proﬁts. Thanks to our single-minded focus on automation we were able to achieve a 71% pretax proﬁt margin, which is unique in our industry. As far as we can see, there is every reason to believe that our winning streak will continue into the future. Not because there are no increasing political and ﬁscal uncertainties visible on both the U.S. domestic and international fronts. But rather because underneath all that trouble there is the growing conviction that newly evolving technologies developed by curious and ambitious scientists and engineers will help us overcome them. AI-fueled productivity gains will save the economy from imploding under rapidly growing deﬁcits and technological solutions will enable us to cope with climate change. Last year I promised that Interactive Brokers will provide the tools to help our customers focus on the crucial questions surrounding these issues. They will inform and will be informed by consensus opinion of what to expect and when, and our customers will be able to adjust their course accordingly. We hope to make these products available for trading within the next few months. The addition of these products to our ever increasing arsenal of account management, research and trading tools together with our growing educational resources will position our platform as a complete destination for investors.

Sustainable Investing Tools • • • • • IMPACT by Interactive BrokersSM – IMPACT by Interactive BrokersSM (‘‘IMPACT App’’) is a unique, simple and intuitive mobile app that helps customers easily align their investment portfolio with their values. The IMPACT App allows customers to select their personal investment criteria from thirteen impact values and principles, and also allow customers to exclude investments based on business practices they would like to avoid.

Interactive Advisors also offers our customers Smart Beta Portfolios which combine the benefits of actively managed fund stock selection techniques with passive ETFs low-cost automation to provide broad market exposure and potentially higher returns, as well as Socially Responsible Investing. 9 Technology Our proprietary technology is the key to our success. We believe that integrating our system with electronic exchanges and market centers worldwide results in transparency, liquidity and efficiencies of scale. Together with the IB SmartRoutingSM system and our low execution costs, this approach reduces overall transaction costs to our IBKR ProSM customers and, in turn, increases our transaction volume and profits (customers who elect to use our IBKR LiteSM offering do not take advantage of our IB SmartRoutingSM technology). Over the past four decades, we have developed an integrated trading system and communications network and have positioned our company as an efficient conduit for the global flow of risk capital across asset and product classes on electronic marketplaces around the world, permitting us to have one of the lowest cost structures in the industry. We believe that developing, maintaining and continuing to enhance our proprietary technology provides us and our customers with the competitive advantage of being able to adapt quickly to the changing environment of our industry and to take advantage of opportunities presented by new exchanges, products, pricing mechanisms or regulatory changes before our competitors. Our proprietary technology infrastructure enables us to provide our customers with the ability to execute trades at among the lowest execution costs in the industry for comparable services. Customer trades are both automatically captured and reported in real time in our system. Our customers can trade on more than 150 electronic exchanges and market centers in 34 countries around the world. These exchanges and market centers are all partially or fully electronic, meaning that customers can buy or sell a product traded on that exchange via an electronic link from their computer or mobile device through our system to the exchange. We offer our products and services through a global communications network that is designed to provide secure, reliable and timely access to the most current market information. We provide our customers with a variety of means to connect to our brokerage systems, including cross connects, dedicated point-to-point data circuits, extranets, virtual private networks and the Internet. Specifically, our customers receive electronic access worldwide via our Trader WorkstationSM (real-time Java-based trading platform), our proprietary Application Programming Interface (‘‘API’’), our IBKR Mobile app, our Client Portal-based Quick Trade feature or industry standard Financial Information Exchange (‘‘FIX’’) connectivity. Customers who want a professional quality trading application with a sophisticated user interface utilize our Trader WorkstationSM, which can be accessed through a desktop or variety of mobile devices. Customers interested in developing programmatic trading utilize our API, which supports multiple programming languages. Large institutions with FIX infrastructure prefer to use our FIX solution for seamless integration of their existing order gathering and reporting applications. While many brokerages, including some online brokerages, rely on employees performing manual procedures to execute many day-to-day functions, we employ proprietary technology to automate, or otherwise facilitate, many of the following functions: • • • • • • • • • account opening and funding; smart order routing resulting in industry-leading execution quality; seamless trading across all types of securities, futures and currencies around the world from one account; diverse order types and analytical tools offered to customers; securities lending and short stock availability; delivery of customer information, such as confirmations, customizable real-time account statements, audit trails and regulatory trade reporting; compliance; customer service; and risk management through automated real-time credit management of all new orders and margin monitoring. 10 Research and Development One of our core strengths is our expertise in the rapid development and deployment of automated technology for the financial markets. Our core software technology is developed internally, and we do not generally rely on outside vendors for software development or maintenance. To achieve optimal performance from our systems and in response to changing market conditions, we continuously rewrite and upgrade our software. Use of the best available technology not only improves our performance but also helps us attract and retain talented developers. Our software development costs are relatively low because the employees who oversee the development of the software are often the same employees who design the application, evaluate its performance, and participate along with our quality assurance professionals in our robust quality assurance testing procedures. The involvement of our developers in each of these processes enables us to add features and further refine our software rapidly. Our internally-developed, fully integrated trading and risk management systems are unique and transact across all product classes. These systems have the flexibility to assimilate new trading venues and new product classes without compromising transaction speed or fault tolerance. Fault tolerance, or the ability to maintain system performance despite trading venue malfunctions or hardware failures, is crucial to ensuring best possible executions for our customers. Our systems are designed to detect trading venue malfunctions and quickly take corrective actions by re-routing pending orders when possible. Our company is technology-focused, and our management team is hands-on and technology-savvy. Most members of the management team participate in algorithm design and supervise the creation of detailed specifications for new applications. The development queue is prioritized and highly disciplined. Progress on programming initiatives is generally tracked on a bi-weekly basis by the Steering Committee and other committees consisting of senior executives. This enables us to prioritize key initiatives and achieve rapid results. All new business involves a software development project. We generally do not engage in any business that we cannot automate and incorporate into our platform prior to entering the business. We achieve a rapid software development and deployment cycle by leveraging a highly integrated, object-oriented development environment. The software code is modular, with each object providing a specific function and being reusable in multiple applications. New software releases are tracked and tested with proprietary automated testing tools. We are not hindered by disparate and often limiting legacy systems assembled through acquisitions. Virtually all our software has been developed and maintained with a unified purpose. For over four decades, we have built and continuously refined our automated and integrated, real-time systems for world-wide trading, risk management, clearing and cash management, among others. We have also assembled a proprietary connectivity network between us and exchanges and market centers around the world. Efficiency and speed in performing prescribed functions are always crucial requirements for our systems. As a result, our systems can assimilate market data, disseminate market prices to customers and update risk management information in real time, across tradable products in all available product classes and across multiple geographies. Risk Management Activities Our risk management policies are developed and implemented by our Steering Committee, which is chaired by our Chief Executive Officer and comprised of senior executives of our various operating subsidiaries. The core of our risk management philosophy is the utilization of our fully integrated computer systems to perform critical risk-management activities on a real-time basis. Our integrated risk management seeks to ensure that each customer’s positions are continuously credit checked and brought into compliance if equity falls short of margin requirements, curtailing bad debt losses. We calculate margin requirements for each of our customers on a real-time basis across all product classes (stocks, options, futures, forex, bonds, mutual funds, ETFs and other financial instruments) and across all currencies. Recognizing that our customers generally are experienced investors, we expect our customers to manage their positions proactively, and we provide tools to facilitate our customers’ position management. However, if a customer’s equity falls below what is required to support that customer’s margin, we will automatically liquidate positions on a real-time basis to bring the customer’s account into margin compliance. We do this to protect ourselves, as well as the customer, from excessive losses. These systems further contribute to our low-cost structure. The entire credit management process is automated. 11 As a safeguard, all liquidations are displayed on custom built liquidation monitoring screens that are part of the toolset our risk management professionals use to minimize market exposure. In addition, our risk management staff uses these displays to monitor the performance of our risk systems at all times across all open markets around the world. Should our systems absorb erroneous market data from exchanges that prompt liquidations, our risk specialists have the capability to temporarily halt liquidations that meet specific criteria. The liquidation halt function is highly restricted. Our customer interfaces include color coding on the account screen and pop-up warning messages to notify customers that they are approaching their margin limits. This feature allows customers to take action, such as entering margin reducing trades, to avoid having their positions liquidated under our automated liquidation algorithm. These tools and real-time margining aid our customers in understanding their trading risk at any moment of the day and help us maintain low commissions. We actively manage our global currency exposure on a continuous basis by maintaining our equity in a basket of currencies we call the GLOBAL. We define the GLOBAL as consisting of fractions of a U.S. dollar, Euro, Japanese yen, British pound, Swiss franc, Chinese renminbi, Indian rupee, Canadian dollar, Australian dollar and Hong Kong dollar. The currencies comprising the GLOBAL and their relative proportions can change over time. Additional information regarding our currency diversification strategy is set forth in ‘‘Quantitative and Qualitative Disclosures about Market Risk’’ in Part II, Item 7A of this Annual Report on Form 10-K. With respect to our remaining market making activities, we employ certain hedging and risk management techniques to protect us from a severe market dislocation. Our automated system evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates the outstanding quotes in our portfolio many times per second. Our model automatically rebalances our positions throughout each trading day to manage risk exposures. Under risk management policies implemented and monitored primarily through our computer systems, reports to management, including risk profiles, profit and loss analysis and trading performance, are prepared on real-time and periodical bases. Although our remaining market making activities are completely automated, the trading process and risk exposures are monitored by a team of individuals who, in real-time, observe various risk parameters of our consolidated positions. Operational Risk and Controls We manage the operational risk inherent in our business and limit potential exposure to operational incidents by maintaining robust and comprehensive controls. Our control environment is designed to ensure that services and controls are resilient during periods of operational stress (e.g., extreme market volatility) and business disruptions. These controls are periodically assessed for both design appropriateness and operating effectiveness by our Enterprise Risk Management and Internal Audit functions. In addition, an Independent Service Auditor annually examines our brokerage operations system and the suitability of the design and operating effectiveness of the related controls (System and Organizational Controls 1 Report). We have automated the full cycle of controls surrounding our businesses. Key automated controls include the following: • • • Our technical operations team continuously monitors our network and the proper functioning of each of our nodes (exchanges and market centers, internet service providers (‘‘ISPs’’), leased customer lines and our own data centers) around the world. Our real-time credit manager software provides pre- and post-execution controls by: • • testing every customer order to ensure that the customer’s account holds enough equity to support the execution of the order, rejecting the order if equity is insufficient or directing the order to an execution destination without delay if equity is sufficient; and continuously updating a customer account’s equity and margin requirements and, if the account’s equity falls below its minimum margin requirements, automatically issuing liquidating orders in a smart sequence designed to minimize the impact on the account’s equity. Our clearing system captures trades in real-time and performs automated reconciliation of trades and positions, corporate action processing, customer account transfer, options exercise, securities lending and inventory management, allowing us to effectively manage operational risk. 12 • • Our accounting system operates with automated data feeds from clearing and banking systems, allowing us to produce financial statements for all parts of our business every day by mid-day on the day following trade date. Our market making system continuously evaluates securities and futures products in which we provide bid and offer quotes and changes our bids and offers in such a way as to maintain an overall hedge and a low-risk profile. The speed of communicating with exchanges and market centers is maximized through continuous software and network engineering maintenance, thereby allowing us to achieve real-time controls over market exposure. Transaction Processing Our transaction processing is automated over the full life cycle of a trade. Our fully automated IB SmartRoutingSM system searches for the best possible combination of prices available at the time a customer order is placed and immediately seeks to execute that order electronically or send it where the order has the highest possibility of execution at the best price. Our market making software generates and disseminates to the exchanges and market centers, in which we still operate, continuous bid and offer quotes on tradable, exchange-listed products. When an order is executed, our systems capture and deliver this information back to the source, either to the customer via the brokerage system or to the market making system, generally within a fraction of a second. Simultaneously, the trade record is written into our clearing system, where it flows through a chain of control accounts that allow us to reconcile trades, positions and money until the final settlement occurs. Our integrated software tracks other important activities, such as dividends, corporate actions, options exercises, securities lending, margining, risk management and funds receipt and disbursement. IB SmartRoutingSM IB SmartRoutingSM searches for the best destination price in view of the displayed prices, sizes and accumulated statistical information about the behavior of market centers at the time an order is placed, then immediately seeks to execute that order electronically. Unlike other smart routers, IB SmartRoutingSM never relinquishes control of the order, and constantly searches for the best price. It continuously evaluates fast-changing market conditions and dynamically re-routes all or parts of the order seeking to achieve optimal execution. For example, for U.S. options, IB SmartRoutingSM can represent each leg of a spread order independently, if needed, and in that event enters each leg at the best possible venue. IB SmartRouting AutorecoverySM re-routes a customer’s U.S. options order in the case of an exchange malfunction, and we absorb the risk of double executions. In addition, IB SmartRoutingSM checks each new order to see if it could be executed against any of its pending orders in our automated trading system (‘‘ATS’’). As the system continues to gain more users, IB SmartRouting exchanges, market centers and penny-priced orders because it increases the possibility of best possible executions for our customers ahead of customers of other brokers. As a result of this feature, our customers have a greater chance of executing limit orders and can do so sooner than those who use less sophisticated routers. and the IBKR ATS facilities become more important for customers in a world of multiple SM Clearing and Margining Our activities in the U.S. are entirely self-cleared. We are a clearing member of OCC (formerly known as the Options Clearing Corporation), The Depository Trust and Clearing Corporation, the Chicago Mercantile Exchange Clearing House, and ICE Clear U.S. In addition, we are fully or partially self-cleared in Canada, the United Kingdom, Switzerland, France, Germany, Belgium, Austria, the Netherlands, Spain, Norway, Sweden, India, Hong Kong, Japan and Australia. Customers Our customers primarily fall into two groups based on services provided, both of which take advantage of our low commissions as well as our best price execution. Cleared customers, the large majority of our customers, use our trade execution and clearing services, low financing rates, high interest paid (when available) and, under our IBKR LiteSM offering, commission-free trades. Non-cleared customers use our trade execution services while choosing to clear with another prime broker or a custodian bank. 13 We currently service approximately 2.56 million cleared customer accounts and have customers residing in over 200 countries and territories around the world. Our target customer is one who requires the latest in trading technology and worldwide access, and who expects low overall transaction and financing costs and market rate interest on idle cash balances. Our customers are mainly comprised of individuals, trading desk professionals, electronic retail brokers, hedge funds, mutual funds, financial advisors, proprietary trading firms, and introducing brokers and banks that require global access. No single customer represented more than 1% of our commissions in 2023. Human Capital As of December 31, 2023, we had 2,932 employees across 27 locations globally. We aim to attract, develop and retain employees to drive our business forward. To help our employees thrive at work and at home, we offer industry-leading benefits programs, including paid leave time for all parents, adoption and fertility support, childcare support, mental health services, and healthcare travel reimbursement. In the U.S., we fund healthcare premiums at no cost to employees. Social Initiatives We believe that communication and connectivity are critical to creating a culture of inclusion, and in 2023 we implemented a new digital platform with over 60 employee-led communities that employees use to engage in shared interests ranging from philanthropy and sports to innovative technologies. In response to the results of our 2023 Employee Engagement Survey, we rolled out new programs to support the well-being of our employees. We implemented a global mental health program operated by an external specialist, which includes peer-to-peer, interactive group sessions and one-on-one sessions to facilitate awareness and education on mental health topics. We also launched a global Steps Challenge to motivate our employees to build fitness into their work routine. We continued to expand our global mentorship program, with more than 120 mentors providing peer-to-peer career support. We believe philanthropic giving is a personal and powerful tool to connect to local communities and causes that matter most to our employees. To facilitate employee giving, we partner with a workplace giving platform in a program that features matching contributions from the Company. Employee and Leadership Development We support career and skill development for our employees through online and in-person training. Our IBKR Training Portal offers over 900 courses encompassing market and industry knowledge building, technical skills, and soft-skills training that supports managers and employees in developing in their roles. We believe managers have an outsized impact on employee experience and careers, so we have invested in supporting managers with content and training focused on coaching, giving and receiving feedback, managing unconscious bias, performance management, and interview skills. We launched the New Manager Development Program to help first-time managers transition and learn from each other. Over 175 leaders completed one of our programs in 2023. In addition, all employees must complete compliance training in many role-relevant areas, meeting or exceeding all regulatory requirements. Topics include Anti-Money Laundering, Anti-Bribery and Corruption, Sanctions, Cybersecurity and Data Privacy. Diversity, Equity and Inclusion We believe a diverse workforce enriches our employees’ and customers’ experience. We are dedicated to promoting a culture of inclusion and attracting and developing a diverse global workforce. To broaden the pool of applicants who apply to our jobs and internships, we partner with organizations like 100 Women in Finance and Girls Who Code. We continue to support our employee resource groups to promote personal growth and professional development for women, minorities and others at the Company. These include our Women’s Resource Group, Military Veterans and Families Group, and Pride Network. We continue to support these communities by running networking events and skills workshops, such as: • Panels with our Non-Executive Board and female members of our Board of Directors; 14 • • • • International Women’s Day events; Learning sessions on Neurodiversity and other topics; Pride Month awareness and events; and Employee wellness events. Sustainability Our Board’s ESG Committee provides ongoing leadership governance for related strategies and initiatives throughout the Company. In 2023, we produced our first Sustainability Report which summarizes the three primary areas of our sustainability strategy: (1) Leadership and Governance, (2) Our People, and (3) Environmental Stewardship. Our Sustainability Report can be found on our website located at www.interactivebrokers.com. The contents of our Sustainability Report are not incorporated by reference into this Annual Report on Form 10-K or in any other report or document we file with the SEC. In 2023, we also completed our baseline Greenhouse Gas (‘‘GHG’’) assessment to help us inventory and analyze our Scope 1 and Scope 2 emissions. We continue to implement sustainable practices that help protect the environment. All of our offices have completed an environmental review to assess current and best practices for energy, water and waste management, and in 2023, we developed our Environmental Standards, a framework for managing our GHG, waste, water and recycling. We also procured renewable power sources for all of our offices through the purchase of renewable energy certificates representing over 95% of our operational footprint. We use third-party providers for data centers. Worldwide, 90% of these data centers use renewable power provided directly through the landlord or via renewable energy certificates. Competition The market for electronic brokerage services is rapidly evolving and highly competitive, and we expect it to remain so. The environment in which we operate has a broad array of competitors ranging from large integrated banks to online brokers to early-stage private companies. Our primary competitors, both in the U.S. and abroad, are other companies that provide electronic brokerage, prime brokerage, and financial advisor and introducing broker products and services. We compete based on numerous factors, including quality of transaction execution, customer experience, products and services, technological excellence and innovation, reputation, global access, and price. Since our inception, we have been transforming the electronic brokerage business through automation and innovation, with software development, product improvement, expansion of products and geographies, and management focus dedicated to this mission. We believe these are significant differentiators that set us apart from our competitors. We experience competition in hiring and retaining qualified employees. The market for qualified personnel in our business is highly competitive and, at various times, the demand in the market for different functions and roles can become especially high, which may oblige us to pay more to attract and retain talent. We also compete on non-monetary forms of compensation, providing what we believe to be a robust set of benefits to our employees. Regulation Our securities and derivatives businesses are extensively regulated by U.S. federal and state regulators, foreign regulatory agencies, and numerous exchanges and self-regulatory organizations of which our subsidiaries are members. In the current era of heightened regulation of financial institutions, we expect to incur increasing compliance costs, along with the industry as a whole. Our approach has been to build many of our regulatory and compliance functions into our integrated order routing, custodial, customer onboarding and transaction processing systems, and augment these systems with experienced staff members. Overview As registered U.S. broker-dealers, Interactive Brokers LLC (‘‘IB LLC’’), IBKR Securities Services LLC (‘‘IBKRSS’’) and Interactive Brokers Corp. are subject to the rules and regulations of the Exchange Act, and as members of various exchanges, we are also subject to such exchanges’ rules and requirements. Additionally, IB LLC is subject to the Commodity Exchange Act and rules promulgated by the Commodity Futures Trading Commission (‘‘CFTC’’) and the various commodity exchanges of which it is a member. We are also subject to 15 the requirements of various self-regulatory organizations such as the Financial Industry Regulatory Authority (‘‘FINRA’’), the Chicago Mercantile Exchange (‘‘CME’’) and the National Futures Association (‘‘NFA’’). Our foreign subsidiaries are similarly regulated under the laws and institutional frameworks of the countries in which they operate. U.S. broker-dealers and futures commission merchants are subject to laws, rules and regulations that cover all aspects of the securities and derivatives business, including: • • • • • • • • • • sales methods; ‘‘know your customer’’ requirements; anti-money laundering requirements; trade practices; use and safekeeping of customers’ funds and securities; capital structure; risk management; record-keeping; financing of customers’ purchases; and conduct of directors, officers and employees. In addition, the businesses that we may conduct are limited by our arrangements with and our oversight by regulators. Participation in new business lines, including trading of new products or participation on new exchanges or in new countries often requires governmental and/or exchange approvals, which may take significant time and resources. As a result, we may be prevented from entering new businesses that may be profitable in a timely manner, or at all. As certain of our subsidiaries are members of FINRA, we are subject to certain regulations regarding changes in control of our ownership. FINRA Rule 1017 generally provides that FINRA approval must be obtained in connection with any transaction resulting in a change in control of a member firm. FINRA defines control as ownership of 25% or more of the firm’s equity by a single entity or person and would include a change in control of a parent company. As a result of these regulations, our future efforts to sell shares or raise additional capital may be delayed or prohibited by FINRA. Net Capital Rule The SEC, FINRA, CFTC and various other regulatory agencies within the U.S. have stringent rules and regulations with respect to the maintenance of specific levels of net capital by regulated entities. Generally, a broker-dealer’s capital is its net worth plus qualified subordinated debt less deductions for certain types of assets. The Net Capital Rule requires that at least a minimum part of a broker-dealer’s assets be maintained in a relatively liquid form. If these net capital rules are changed or expanded, or if there is an unusually large charge against our net capital, our operations that require the intensive use of capital would be limited. A large operating loss or charge against our net capital could adversely affect our ability to expand or even maintain these current levels of business, which could have a material adverse effect on our business and financial condition. The U.S. regulators impose rules that require notification when net capital falls below certain predefined criteria. These rules also dictate the ratio of debt-to-equity in the regulatory capital composition of a broker-dealer and constrain the ability of a broker-dealer to expand its business under certain circumstances. If a firm fails to maintain the required net capital, it may be subject to suspension or revocation of registration by the applicable regulatory agency, and suspension or expulsion by these regulators could ultimately lead to the firm’s liquidation. Additionally, the Net Capital Rule and certain FINRA rules impose requirements that may have the effect of prohibiting a broker-dealer from distributing or withdrawing capital and requiring prior notice to U.S. regulators and approval from FINRA for certain capital withdrawals. 16 Our foreign subsidiaries are similarly regulated with regard to capital requirements in support of their brokerage activities. As of December 31, 2023, aggregate excess regulatory capital for all of the operating subsidiaries was $10.2 billion. IB LLC is subject to the Uniform Net Capital Rule (Rule 15c3-1) under the Exchange Act and to the CFTC’s minimum financial requirements (Regulation 1.17) under the Commodities Exchange Act. Additionally, Interactive Brokers Canada Inc. (‘‘IBC’’) is subject to the Canadian Investment Regulatory Organization (‘‘CIRO’’) risk adjusted capital requirement; Interactive Brokers (U.K.) Limited (‘‘IBUK’’) is subject to the United Kingdom’s (‘‘U.K.’’) Financial Conduct Authority (‘‘FCA’’) financial resources requirement; Interactive Brokers Ireland Limited (‘‘IBIE’’) is subject to the Central Bank of Ireland (‘‘CBI’’) financial resources requirement; IBKR Financial Services AG (‘‘IBKRFS’’) is subject to the Swiss Financial Market Supervisory Authority (‘‘FINMA’’) eligible equity requirement; Interactive Brokers Central Europe Zrt. (‘‘IBCE’’) is subject to the Hungarian National Bank (‘‘MNB’’) financial resource requirement; Interactive Brokers (India) Private Limited (‘‘IBI’’) is subject to the National Stock Exchange of India net capital requirements; Interactive Brokers Hong Kong Limited (‘‘IBHK’’) is subject to the Hong Kong Securities and Futures Commission (‘‘SFC’’) financial resource requirement; Interactive Brokers Securities Japan, Inc. (‘‘IBSJ’’) is subject to the Japanese Financial Services Agency (‘‘FSA’’) capital requirements; Interactive Brokers Singapore Pte. Ltd. (‘‘IBSG’’) is subject to the Monetary Authority of Singapore (‘‘MAS’’) capital requirements; and Interactive Brokers Australia Pty Limited (‘‘IBA’’) is subject to the Australian Securities Exchange (‘‘ASX’’) liquid capital requirement. The table below summarizes capital, capital requirements and excess regulatory capital as of December 31, 2023.

For additional information regarding our net capital requirements see Note 16 – ‘‘Regulatory Requirements’’ to the audited consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K. Protection of Customer Assets To conduct customer activities, IB LLC is obligated under rules mandated by its primary regulators, the SEC and the CFTC, to segregate cash or qualified securities belonging to customers. In accordance with the Securities Exchange Act of 1934, IB LLC is required to maintain separate bank accounts for the exclusive benefit of customers. In accordance with the Commodity Exchange Act, IB LLC is required to segregate all monies, securities and property received from commodities customers in specially designated accounts. IBC, IBUK, IBIE, IBCE, IBI, IBHK, IBSJ, IBSG and IBA are subject to similar requirements within their respective jurisdictions. To further enhance the protection of our customers’ assets, IB LLC performs daily (i.e., instead of the required weekly) customer reserve computations along with daily adjustments of the money set aside in safekeeping for our customers. Supervision and Compliance Our Compliance department supports and seeks to ensure proper operations of our business in accordance with applicable regulatory requirements. The philosophy of the Compliance department, and the Company as a whole, is to build automated systems to try to minimize manual steps in the compliance process and then to augment these systems with experienced staff members who apply their judgment where needed. We have built automated systems to handle wide-ranging compliance issues such as trade and audit trail reporting, financial operations reporting, enforcement of short sale rules, enforcement of margin rules and pattern day trading restrictions, recording and review of employee correspondence, archival of required records, execution quality and order routing reports, approval and documentation of new customer accounts, surveillance of customer trading for 17 market manipulation or abuse or violations of exchange rules, and anti-money laundering and anti-fraud surveillance in line with our anti-money laundering policies. Our automated operations and automated compliance systems provide substantial efficiencies to our Compliance department. As part of this continuing effort, we have implemented a robust case management and surveillance system and increased our Compliance staffing over the past several years to meet the growing regulatory burdens faced by all industry participants. Our electronic brokerage subsidiaries have Chief Compliance Officers who report to the Chief Executive Officer or business head for their subsidiary, and to the Global Chief Regulatory Officer (or regional Compliance Head). In the U.S., the Chief Compliance Officer and certain other senior staff members are FINRA and NFA registered principals with supervisory responsibility over the compliance aspects of our businesses. Similar roles are undertaken by staff in certain non-U.S. locations as well. Staff members in the Compliance department and in other departments are also registered with FINRA, NFA or other regulatory organizations. Patriot Act and Increased Anti-Money Laundering (‘‘AML’’) and ‘‘Know Your Customer’’ Obligations Registered broker-dealers traditionally have been subject to a variety of rules that require that they ‘‘know their customers’’ and monitor their customers’ transactions for suspicious activities. Under the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the ‘‘USA Patriot Act’’), broker-dealers are subject to even more stringent requirements. Likewise, the SEC, CFTC, foreign regulators, and the various exchanges and self-regulatory organizations, of which our operating subsidiaries are members, have passed numerous AML and customer due diligence rules. Significant criminal and civil penalties can be imposed for violations of the USA Patriot Act, and significant fines and regulatory penalties can also be imposed for violations of other governmental and self-regulatory organization AML rules. As required by the USA Patriot Act and other rules, we have established comprehensive AML and customer identification procedures, and designated AML Compliance Officers for each electronic brokerage subsidiary; and we provide formal AML training to our AML, customer facing, and other relevant employees, and conduct regular independent audits of our AML programs. Our AML screening is conducted using a mix of automated and manual reviews and has been structured to comply with regulations in various jurisdictions. We collect required information through our new account opening process and screen accounts against databases for the purposes of identity verification and for review of potential negative information and appearance on government sanction lists, including the Office of Foreign Assets and Control, Specially Designated Nationals and Blocked Persons lists and several other global, United Nations, European Union (‘‘EU’’) and other non-U.S. sanction lists. Additionally, we have designed and implemented restrictions to prevent certain types of high-risk activity, including potentially manipulative patterns of trading or higher risk patterns of money movement. We generate and review a sophisticated suite of surveillance reports and queues to identify potential money laundering, market manipulation or abuse, fraud and other suspicious activities. Dodd-Frank Reform Act The Dodd-Frank Wall Street Reform and Consumer Protection Act imposes strict reporting and disclosure requirements on the financial services industry. We maintain a robust system for evidence of our supervisory review of controls over financial reporting and management monitors accounting and regulatory rulemaking developments for their potential effect on our financial statements and internal controls over financial reporting. Business Continuity Planning Federal regulators and industry self-regulatory organizations have passed a series of rules in the past several years requiring regulated firms to maintain business continuity plans that describe what actions firms would take in the event of a disaster (such as a fire, natural disaster, climate-related event or terrorist incident) that might significantly disrupt operations. We have developed business continuity plans that describe steps that we and our employees would take in the event of various scenarios. We have built backup capabilities for key operations performed at our regional offices in North America, Europe and Asia that would be utilized in the event of a significant outage at our main data center or primary office locations. In addition, we have strengthened our technical infrastructure and have built redundancy of systems so that most operations can be handled from multiple offices or remotely. Spurred by the COVID-19 pandemic, we have substantially enhanced this infrastructure and our remote access capabilities so that most employees, including all with critical job functions, can work remotely. We continually evaluate opportunities to further our business continuity planning efforts. 18 Foreign Regulation Our international subsidiaries are subject to extensive regulation in the various jurisdictions where they have operations. The most significant of our international subsidiaries are: IBC, registered to do business in Canada as an investment dealer; IBUK, registered to do business in the U.K. as a broker; IBIE, registered in Ireland as an investment firm; IBKRFS, registered to do business in Switzerland as a securities dealer; IBCE, registered in Hungary as an investment firm; IBI, registered to do business in India as a stock broker; IBHK, registered to do business in Hong Kong as a securities dealer; IBSJ, registered in Japan as a financial instruments firm; IBSG, registered in Singapore as a capital markets firm; and IBA, registered to do business in Australia as a securities dealer and futures broker.

RISK FACTORS We face a variety of risks that are substantial and inherent in our businesses, including market, liquidity, credit, operational, legal and regulatory. In addition to the risks identified elsewhere in this Annual Report on Form 10-K, the following is a summary of the risk factors that apply to our business results of operations and financial condition. Please read the detailed discussion of these risks following the summary. 20 Risks Related to Our Company Structure • • Future sales of our common stock in the public market could lower our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us. Control by Mr. Thomas Peterffy of a majority of the combined voting power of our common stock may give rise to conflicts of interests and could discourage a change of control that other stockholders may favor, which could negatively affect our stock price, and adversely affect stockholders in other ways. • We depend on IBG LLC to distribute cash to us in amounts sufficient to pay our tax liabilities and other expenses. • We are required to pay Holdings for the benefit relating to additional tax depreciation or amortization deductions we claim as a result of the tax basis step-up our subsidiaries received in connection with our initial public offering (‘‘IPO’’) and certain subsequent redemptions of Holdings membership interests. • Certain provisions in our amended and restated certificate of incorporation may prevent efforts by our stockholders to change our direction or management. Risks Related to Our Business • Macroeconomic, geopolitical and other challenges and uncertainties could have a negative impact on our business. Our business could be harmed by a systemic market event. Damage to our reputation could harm our business. The impact of a public health emergency may have a material adverse impact on our business and results of operations. Our future success will depend on our response to the demand for new services, products and technologies. The loss of our key employees would materially adversely affect our business. • • • • • • We may not pay dividends on our common stock at any time in the foreseeable future. • Our direct market access clearing and non-clearing brokerage operations face intense competition. • We are subject to potential losses as a result of our clearing and execution activities. • We are exposed to risks associated with our international operations. • We are subject to counterparty risk whereby defaults by parties with whom we do business can have an adverse effect on our business, financial condition and results of operations. • • Any future acquisitions may result in significant transaction expenses, integration and consolidation risks and risks associated with entering new markets, and we may be unable to profitably operate our consolidated company. Because our revenues and profitability depend on trading volume and interest rate levels, they are prone to significant fluctuations and are difficult to predict. • We may incur material trading losses from our market making activities. • Reduced spreads in securities pricing, levels of trading activity and trading through market makers could harm our business. • We may incur losses in our market making activities in the event of failures of our proprietary pricing model. • The valuation of the financial instruments we hold may result in large and occasionally anomalous swings in the value of our positions and in our earnings in any period. 21 • We are exposed to losses due to lack of perfect information. • Rules governing designated market makers may require us to make unprofitable trades or prevent us from making profitable trades. • • • Our risk management policies and procedures may not be fully effective in mitigating our risk exposure in all market environments or against all types of risks. Risks Related to Laws, Regulations and Litigation Our future efforts to sell shares or raise additional capital may be delayed or prohibited by regulations. Regulatory and legal uncertainties could harm our business. • We are subject to risks relating to litigation and potential securities laws liability. • Heightened regulatory and legislative requirements and changes in the U.S. and globally have increased our compliance, regulatory and other risks and costs. • We may incur additional tax expense or become subject to additional tax liabilities. Risks Related to Our Intellectual Property, Technology, Cybersecurity and Data Privacy • We may not be able to protect our intellectual property rights or may be prevented from using intellectual property necessary for our business. • Our reliance on our computer software could cause us great financial harm in the event of any disruption or corruption of our computer software. We may experience technology failures while developing our software. • We depend on our proprietary technology, and our future results may be impacted if we cannot maintain technological superiority in our industry. • We do not have fully redundant systems. System failures could harm our business. • Failure of third-party systems on which we rely could adversely affect our business. • Internet-related issues may reduce or slow the growth in the use of our services in the future. • We could be the target of a cyber-attack or experience a cybersecurity incident that impairs internal systems, degrades services we provide to customers, or results in a data compromise, causing reputational or monetary damages as a consequence. • We are subject to stringent and complex data privacy rules. Failure to comply with these rules could have an adverse effect on our business, financial condition, and results of operation. Risks Related to Cryptocurrency • We rely on third-party Cryptocurrency Service Providers (‘‘CSPs’’) to provide our customers the ability to access cryptocurrency trading and custody services. • A data breach at the CSP may result in irreversible losses, which would adversely affect our customers and our business. • We may encounter technical issues which would result in disruption or interruption of our customers’ access to their CSP accounts. • • Changes in laws and regulations regarding cryptocurrency may negatively impact our ability to enable our customers to buy, hold and sell cryptocurrencies in the future and may adversely affect our business. A loss event incurred by the CSP may adversely impact our operating results. 22 Risks Related to Our Company Structure Future sales of our common stock in the public market could lower our stock price, and any additional capital raised by us through the sale of equity or convertible securities may dilute your ownership in us. The members of Holdings have the right to cause the redemption of their Holdings membership interests over time in connection with offerings of shares of our common stock. We intend to sell additional shares of common stock in public offerings in the future, which may include offerings of our common stock to finance future purchases of IBG LLC membership interests which, in turn, will finance corresponding redemptions of Holdings membership interests. These offerings and related transactions are anticipated to occur at least annually into the future. The size and occurrence of these offerings may be affected by market conditions. We may also issue additional shares of common stock or convertible debt securities to finance future acquisitions or business combinations. We currently have approximately 107.0 million outstanding shares of common stock. Assuming no anti-dilution adjustments based on combinations or divisions of our common stock, the offerings referred to above could result in the issuance by us of up to an additional approximately 314.0 million shares of common stock. It is possible, however, that such shares could be issued in one or a few large transactions. We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of shares of our common stock may have on the market price of our common stock. Sales of substantial amounts of our common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may cause the market price of our common stock to decline. Control by Mr. Thomas Peterffy of a majority of the combined voting power of our common stock may give rise to conflicts of interests and could discourage a change of control that other stockholders may favor, which could negatively affect our stock price, and adversely affect stockholders in other ways. Mr. Thomas Peterffy, our founder and Chairman, and his affiliates beneficially own approximately 91.3% of the economic interests and all of the voting interests in Holdings, which owns all of our Class B common stock, representing approximately 74.6% of the combined voting power of all classes of our voting stock. As a result, Mr. Peterffy has the ability to elect all of the members of our Board of Directors and thereby to control our management and affairs, including determinations with respect to acquisitions, dispositions, material expansions or contractions of our business, entry into new lines of business, borrowings, issuances of common stock or other securities, and the declaration and payment of dividends on our common stock. In addition, Mr. Peterffy is able to determine the outcome of all matters requiring stockholder approval and will be able to cause or prevent a change of control of our company or a change in the composition of our Board of Directors and could preclude any unsolicited acquisition of our company. The concentration of ownership could discourage potential takeover attempts that other stockholders may favor and could deprive stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and this may adversely affect the market price of our common stock. Moreover, because of Mr. Peterffy’s substantial ownership, we are eligible to be and are, treated as a ‘‘controlled company’’ for purposes of the Nasdaq Marketplace Rules. As a result, we are not required by Nasdaq to have a majority of independent directors or to maintain Compensation and Nominating and Corporate Governance Committees composed entirely of independent directors to continue to list the shares of our common stock on Nasdaq. Our Compensation Committee is comprised of Messrs. Thomas Peterffy (Chairman of the Compensation Committee), Earl H. Nemser (our Vice Chairman) and Milan Galik (our Chief Executive Officer). Mr. Peterffy’s membership on the Compensation Committee may give rise to conflicts of interests in that Mr. Peterffy is able to influence all matters relating to executive compensation, including his own compensation. We depend on IBG LLC to distribute cash to us in amounts sufficient to pay our tax liabilities and other expenses. We are a holding company and our primary assets are our approximately 25.4% equity interest in IBG LLC and our controlling interest and related rights as the sole managing member of IBG LLC and, as such, we operate and control all of the business and affairs of IBG LLC and are able to consolidate IBG LLC’s financial results into our financial statements. We have no independent means of generating revenues. IBG LLC is treated as a partnership for U.S. federal income tax purposes and, as such, is not subject to U.S. federal income tax. Instead, its taxable income is allocated on a pro rata basis to Holdings and us. Accordingly, we incur income taxes on our proportionate share of the net taxable income of IBG LLC, and also incur expenses related to our operations. 23 We intend to cause IBG LLC to distribute cash to its members in amounts at least equal to that necessary to cover their tax liabilities, if any, with respect to the earnings of IBG LLC. To the extent we need funds to pay such taxes, or for any other purpose, and IBG LLC is unable to provide such funds, it could have a material adverse effect on our business, financial condition and results of operations. We are required to pay Holdings for the benefit relating to additional tax depreciation or amortization deductions we claim as a result of the tax basis step-up our subsidiaries received in connection with our initial public offering (‘‘IPO’’) and certain subsequent redemptions of Holdings membership interests. In connection with our IPO, we purchased interests in IBG LLC from Holdings for cash. In connection with redemptions of Holdings membership interests, we acquired additional interests in IBG LLC by issuing shares of Class A common stock in exchange for an equivalent number of shares of member interests in IBG LLC (the ‘‘Redemptions’’). In addition, IBG LLC membership interests held by Holdings may be sold in the future to us and financed by our issuances of shares of our common stock. The initial purchase and the Redemptions did, and the subsequent purchases may, result in increases in the tax basis of the tangible and intangible assets of IBG LLC and its subsidiaries that otherwise would not have been available. Such increase will be approximately equal to the amount by which our stock price at the time of the purchase exceeds the income tax basis of the assets of IBG LLC underlying the IBG LLC interests acquired by us. These increases in tax basis will result in increased deductions in computing our taxable income and resulting tax savings for us generally over the 15-year period which commenced with the initial purchase and subsequent purchases, respectively. We have agreed to pay 85% of these tax savings, if any, to Holdings as they are realized as additional consideration for the IBG LLC interests that we acquire, with the balance to be retained by us. As a result of the IPO and the Redemptions by Holdings, the increase in the tax basis attributable to our interest in IBG LLC is $2.1 billion. The tax savings that we would actually realize as a result of this increase in tax basis likely would be significantly less than this amount multiplied by our effective tax rate due to a number of factors, including the allocation of a portion of the increase in tax basis to foreign or non-depreciable fixed assets, the impact of the increase in the tax basis on our ability to use foreign tax credits and the rules relating to the amortization of intangible assets, for example. Based on facts and assumptions as of December 31, 2023, including that subsequent purchases of IBG LLC interests will occur in fully taxable transactions, the potential tax basis increase resulting from the historical and future purchases of the IBG LLC interests held by Holdings could be as much as $12.4 billion. The actual increase in tax basis depends, among other factors, upon the price of shares of our common stock at the time of the purchase and the extent to which such purchases are taxable and, as a result, could differ materially from this amount. Our ability to achieve benefits from any such increase, and the amount of the payments to be made under the Tax Receivable Agreement, depends upon a number of factors, as discussed above, including the timing and amount of our future income. The tax basis increase of $12.4 billion assumes that (a) all remaining IBG LLC membership interests held by Holdings are purchased by us in one or more taxable transactions and (b) such purchases in the future are made at prices that reflect the closing share price as of December 31, 2023. If the Internal Revenue Service (‘‘IRS’’) successfully challenges the tax basis increase, under certain circumstances, we could be required to make payments to Holdings under the Tax Receivable Agreement in excess of our cash tax savings. Certain provisions in our amended and restated certificate of incorporation may prevent efforts by our stockholders to change our direction or management. Provisions contained in our amended and restated certificate of incorporation could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. For example, our amended and restated certificate of incorporation authorizes our Board of Directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock, without any vote or action by our stockholders. We could issue a series of preferred stock that could impede the completion of a merger, tender offer or other takeover attempt. These provisions may discourage potential acquisition proposals and may delay, deter or prevent a change of control of us, including through transactions, and, in particular, unsolicited transactions, that some or all of our stockholders might consider to be desirable. As a result, efforts by our stockholders to change our direction or management may be unsuccessful. 24 Risks Related to Our Business Macroeconomic, geopolitical and other challenges and uncertainties could have a negative impact on our business. We are affected by domestic and international macroeconomic and political conditions, as well as, the level of interest rates, inflation, and by fiscal and monetary policy. Our business depends in part on the level of global trading volumes and volatility, which are affected by factors beyond our control. These factors may cause a weakness in securities markets, leading to a slowdown in trading volumes, which would result in reduced transaction revenues. Changes in tax law and regulation, or market uncertainty caused by a change in the political environment, may negatively affect our business. Our international operations may also be subject to risk of loss due to political, economic or financial instability, unexpected changes in regulatory requirements, tax laws, and changes in governmental or central bank policies. These risks could have a material adverse effect on our business, financial condition and results of operations. Our business could be harmed by a systemic market event. Some market participants could be overleveraged. In case of sudden, large price movements, such market participants may not be able to meet their obligations to brokers who, in turn, may not be able to meet their obligations to their counterparties. As a result, the financial system or a portion thereof could collapse, and the impact of such an event could be catastrophic to our business. Damage to our reputation could harm our business. Maintaining our reputation is critical to attracting and maintaining customers, investors, and employees. If we fail to address, or appear to fail to address, issues that may give rise to reputational risk, we could significantly harm our business. These issues may include, but are not limited to, any of the risks discussed in this Item 1A, including appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money laundering, cybersecurity and data privacy, record-keeping, sales and trading practices, and employee misconduct. Adverse developments could impair our reputation and materially adversely affect our business, financial condition and results of operations. The impact of a public health emergency may have a material adverse impact on our business and results of operations. The response of governments and societies to a public health emergency, which could include temporary closures of certain businesses; social distancing; travel restrictions, ‘‘shelter in place’’ and other governmental regulations; and reduced consumer spending due to job losses, may significantly impact volatility in the financial, commodities and energy markets, and general economic conditions. These measures may negatively impact businesses, market participants, our counterparties and customers, and the global economy and could continue for a prolonged period of time. Our net interest income and profitability could be negatively affected by lower benchmark interest rates caused by central banks lowering target benchmark rates in an attempt to buffer their economies from a public health emergency. As a result of our hybrid work model, which we adopted for our offices globally, any disruption to our information technology systems, including from cyber incidents, could have a material adverse effect on our business. We have taken measures to maintain the health and safety of our employees, but widespread illness could negatively affect staffing levels within certain functions or locations. In addition, our ability to recruit, hire and onboard employees could be negatively impacted by a public health emergency. The impact of a public health emergency on our future financial results could be significant but currently cannot be quantified, as it would depend on numerous evolving factors that cannot be accurately predicted, including, but not limited to, the duration and spread of the public health emergency; its impact on our customers, employees and vendors; governmental regulations in response to the public health emergency; and the overall impact of the public health emergency on the economy and society, among other factors. Any of these events, alone or in combination with others, could exacerbate many of the risk factors discussed or incorporated by reference herein and could have a material adverse effect on our business, financial condition and results of operations. 25 Our future success will depend on our response to the demand for new services, products and technologies. The demand for our services that rely on electronic communications gateways, is characterized by: • • • • rapid technological change; changing customer demands; the need to enhance existing services and products or introduce new services and products; and evolving industry standards. New services, products and technologies may render our existing services, products and technologies less competitive. Our future success will depend, in part, on our ability to respond to the demand for new services, products and technologies on a timely and cost-effective basis and to adapt to technological advancements and changing standards to address the increasingly sophisticated requirements and varied needs of our customers and prospective customers. We cannot assure you that we will be successful in developing, introducing or marketing new services, products and technologies. In addition, we may experience difficulties that could delay or prevent the successful development, introduction or marketing of these services and products, and our new service and product enhancements may not achieve market acceptance. Any failure on our part to anticipate or respond adequately to technological advancements, customer requirements or changing industry standards, or any significant delays in the development, introduction or availability of new services, products or enhancements could have a material adverse effect on our business, financial condition and results of operations. The loss of our key employees would materially adversely affect our business. Our key executives have substantial experience and have made significant contributions to our business, and our continued success is dependent upon the retention of our key management executives, as well as the services provided by our staff of trading system, technology and programming specialists and a number of other key managerial, marketing, planning, financial, technical and operations personnel. The loss of such key personnel could have a material adverse effect on our business. Growth in our business is dependent, to a large degree, on our ability to retain and attract such employees. We may not pay dividends on our common stock at any time in the foreseeable future. As a holding company for our interest in IBG LLC, we will be dependent upon the ability of IBG LLC to generate earnings and cash flows and distribute them to us so that we may pay any dividends to our stockholders. To the extent (if any) that we have excess cash, any decision to declare and pay dividends in the future will be made at the discretion of our Board of Directors and will depend on, among other things, our results of operations, financial conditions, cash requirement, contractual restrictions and other factors that our Board of Directors may deem relevant. Since the second quarter of 2011, we have declared and paid a quarterly cash dividend of $0.10 per share. Although not required, we currently intend to pay quarterly dividends of $0.10 per share to our common stockholders for the foreseeable future. Our direct market access clearing and non-clearing brokerage operations face intense competition. With respect to our direct market access brokerage business, the market for electronic and interactive bidding, offering and trading services in connection with equities, options and futures is rapidly evolving and intensely competitive. We expect competition to continue and intensify in the future. Our current and potential future competition principally comes from five categories of competitors: • • • • • prime brokers who, in an effort to satisfy the demands of their customers for hands-on electronic trading facilities, universal access to markets, smart routing, better trading tools, and lower commissions and financing rates, have embarked upon building such facilities and product and service enhancements; direct market access and online equity brokers, and online options and futures firms; zero commission brokers, while technically not offering direct market access, who use simplified interfaces and a limited product offering to attract new market participants; software development firms and vendors who create global trading networks and analytical tools and make them available to brokers; and traditional brokers. 26 In addition, we compete with financial institutions, mutual fund sponsors and other organizations, many of which provide online, direct market access or other investing services. A number of brokers provide our technology and execution services to their customers, and these brokers can become our competitors if they develop their own technology. Some of our competitors in this area have greater name recognition, longer operating histories and significantly greater financial, technical, marketing and other resources than we have and offer a wider range of services and financial products than we do. Some of our competitors may also have an ability to charge lower or zero commissions. We cannot assure you that we will be able to compete effectively or efficiently with current or future competitors. These increasing levels of competition in the online trading industry could significantly harm this aspect of our business. We are subject to potential losses as a result of our clearing and execution activities. As a clearing member firm providing financing services to certain of our brokerage customers, we are ultimately responsible for their financial performance in connection with various securities and derivatives transactions. Our clearing operations require a commitment of our capital and, despite safeguards implemented by our software, involve risks of losses due to the potential failure of our customers to perform their obligations under these transactions. If our customers default on their obligations, we remain financially liable for such obligations, and although these obligations are collateralized, we are subject to market risk in the liquidation of customer collateral to satisfy those obligations. There can be no assurance that our risk management procedures will be adequate. Any liability arising from clearing operations could have a material adverse effect on our business, financial condition and results of operations. As a clearing member firm of securities and derivatives clearing houses in the U.S. and abroad, we are also exposed to clearing member credit risk. Securities and derivatives clearing houses require member firms to deposit cash, stock and/or government securities for margin requirements and to clearing funds. If a clearing member defaults in its obligations to the clearing house in an amount larger than its own margin and clearing fund deposits, the shortfall is absorbed pro rata from the deposits of the other clearing members. Many clearing houses of which we are members also have the authority to assess their members for additional funds if the clearing fund is depleted. A large clearing member default could result in a substantial cost to us if we are required to pay such assessments. We are exposed to risks associated with our international operations. During 2023, approximately 30% of our net revenues were generated by our operating subsidiaries outside the U.S. We are exposed to risks and uncertainties inherent in doing business in international markets, particularly in the heavily regulated brokerage industry. Such risks and uncertainties include political, economic and financial instability; unexpected changes in regulatory requirements, tariffs and other trade barriers; exchange rate fluctuations; applicable currency controls; and difficulties in staffing, including reliance on newly hired local experts, and managing foreign operations. These risks could cause a material adverse effect on our business, financial condition and results of operations. We are subject to counterparty risk whereby defaults by parties with whom we do business can have an adverse effect on our business, financial condition and results of operations. We are exposed to the risk of loss if a customer, counterparty or issuer fails to perform its obligations under contractual terms. Our counterparty risk is primarily from margin loans extended to customers, securities purchased under agreements to resell (‘‘repos’’), securities borrowing and lending arrangements, cash and/or collateral deposited with clearing houses, exchanges, banks, securities firms and other financial counterparties, all of which may result in credit exposure in the event the counterparty defaults on their obligations to us due to bankruptcy, lack of liquidity, operational failure or other reasons. Our customer margin credit exposure is to a great extent mitigated by our policy of automatically evaluating each account throughout the trading day and closing out positions automatically for accounts that are found to be under-margined. While this methodology is effective in most situations, it may not be effective in situations in which no liquid market exists for the relevant securities or commodities or in which, for any reason, automatic liquidation for certain accounts has been disabled. If no liquid market exists or automatic liquidation has been 27 disabled, we are subject to risks inherent in extending credit, especially during periods of rapidly declining markets. Any loss or expense incurred due to defaults by our customers in failing to repay margin loans or to maintain adequate collateral for these loans would cause harm to our business, financial condition and results of operations. Repos are collateralized by securities with a market value in excess of the obligation under the contract and are cleared and marked to market through a central clearing counterparty. Securities lending agreements are collateralized by deposits of cash or securities. We attempt to minimize credit risk associated with these activities by monitoring collateral values daily and requiring additional collateral to be deposited with or returned to us as permitted under contractual provisions. Similarly, over-the-counter transactions, such as contracts for differences (‘‘CFDs’’), are marked to market daily and are conducted with counterparties that have undergone a thorough credit review. Any loss or expense incurred due to defaults by our counterparties in failing to fulfill their contractual obligations would cause harm to our business, financial condition and results of operations. In addition, as a clearing member of several central clearing houses, we participate in the mutualization of risk and could incur financial losses in the event of default by other clearing members. Although we regularly review our credit exposures, default risk may arise from events or circumstances that are difficult to detect or foresee. Any future acquisitions may result in significant transaction expenses, integration and consolidation risks and risks associated with entering new markets, and we may be unable to profitably operate our consolidated company. Although our growth strategy has not focused historically on acquisitions, we may in the future engage in evaluations of potential acquisitions and new businesses. We may not have the financial resources necessary to consummate any acquisitions in the future or the ability to obtain the necessary funds on satisfactory terms. Any future acquisitions may result in significant transaction expenses and risks associated with entering new markets in addition to integration and consolidation risks. Because acquisitions historically have not been a core part of our growth strategy, we have little experience in successfully utilizing acquisitions. We may not have sufficient management, financial and other resources to integrate any such future acquisitions or to successfully operate new businesses and we may be unable to profitably operate our expanded company. Because our revenues and profitability depend on trading volume and interest rate levels, they are prone to significant fluctuations and are difficult to predict. Our revenues are dependent on the level of trading activity on securities and derivatives exchanges in the U.S. and abroad and on the general level of interest rates. In the past, our revenues and operating results have varied significantly from period to period primarily due to movements and trends in the underlying markets and to fluctuations in trading and interest rate levels. As a result, period to period comparisons of our revenues and operating results may not be meaningful, and future revenues and profitability may be subject to significant fluctuations or declines. We may incur material trading losses from our market making activities. A portion of our revenues and operating profits is derived from our trading as principal in our role as a market maker. We may incur trading losses relating to these activities since each primarily involves the purchase or sale of securities for our own account. In any period, we may incur trading losses in a significant number of securities for a variety of reasons including: • • • price changes in securities; lack of liquidity in securities in which we have positions; and the required performance of our market making obligations. These risks may limit or restrict our ability to either resell securities we purchased or to repurchase securities we sold. In addition, we may experience difficulty borrowing securities to make delivery to purchasers to whom we 28 sold short, or lenders from whom we have borrowed. From time to time, we may have large position concentrations in securities of a single issuer or issuers engaged in a specific industry or traded in a particular market. Such a concentration could result in higher trading losses than would occur if our positions and activities were less concentrated. In our role as a market maker, we attempt to derive a profit from the difference between the prices at which we buy and sell, or sell and buy, securities. However, competitive forces often require us to match the quotes other market makers display and to hold varying amounts of securities in inventory. By having to maintain inventory positions, we are subjected to a high degree of risk. We cannot assure you that we will be able to manage such risk successfully or that we will not experience significant losses from such activities, which could have a material adverse effect on our business, financial condition and results of operations. Reduced spreads in securities pricing, levels of trading activity and trading through market makers could harm our business. Computer-generated buy/sell programs and other technological advances and regulatory changes in the marketplace may continue to tighten spreads on securities transactions. Tighter spreads and increased competition could make our remaining market making activities less profitable. We may incur losses in our market making activities in the event of failures of our proprietary pricing model. Our market making activities are substantially dependent on the accuracy of our proprietary pricing mathematical model, which continuously evaluates and monitors the risks inherent in our portfolio, assimilates market data and reevaluates our outstanding quotes many times per second. Our model is designed to automatically rebalance our positions throughout the trading day to manage risk exposures on our positions in options, futures and the underlying securities. In the event of a flaw in our pricing model and/or a failure in the related software, our pricing model may lead to unexpected and/or unprofitable trades, which may result in material trading losses. The valuation of the financial instruments we hold may result in large and occasionally anomalous swings in the value of our positions and in our earnings in any period. The market prices of our long and short positions are reflected on our books at closing prices which are typically the last trade price before the official close of the primary exchange on which each such security trades. If prices of derivatives and their underlying securities close out of alignment, there may be large and occasionally anomalous swings in the value of our positions daily and, accordingly, in our earnings in any period. This is especially true on the last business day of each calendar quarter. We are exposed to losses due to lack of perfect information. As market makers, we provide liquidity by buying from sellers and selling to buyers. Quite often, we trade with others who have different information than we do, and as a result, we may accumulate unfavorable positions preceding large price movements in companies. Should the frequency or magnitude of these events increase, our losses will likely increase correspondingly. Rules governing designated market makers may require us to make unprofitable trades or prevent us from making profitable trades. Designated market makers are granted certain rights and have certain obligations to ‘‘make a market’’ in a particular security. They agree to specific obligations to maintain a fair and orderly market. In acting as a designated market maker, we are subjected to a high degree of risk by having to support an orderly market. In this role, we may at times be required to make trades that adversely affect our profitability. In addition, we may at times be unable to trade for our own account in circumstances in which it may be to our advantage to trade, and we may be obligated to act as a principal when buyers or sellers outnumber each other. In those instances, we may take a position counter to the market, buying or selling securities to support an orderly market. Additionally, the rules of the markets which govern our activities as a designated market maker are subject to change. If these rules are made more stringent, our trading revenues and profits as a designated market maker could be adversely affected. 29 Our risk management policies and procedures may not be fully effective in mitigating our risk exposure in all market environments or against all types of risks. We seek to manage, monitor and control our market, credit, operational, liquidity, and legal and regulatory compliance risks through risk management policies developed and implemented by our Steering Committee, which is chaired by our Chief Executive Officer and comprised of senior executives of our various operating subsidiaries. However, there can be no assurance that our procedures will be adequate. Historically, market conditions have included unprecedented market events which highlighted the limitations inherent in using historical data to manage risk. While we employ a broad and diversified set of risk management tools, they cannot anticipate every economic and financial outcome or the specifics and timing of such outcomes, as a result a failure in our risk management policies and procedures could have a material adverse effect on our business, financial condition and results of operations. See ‘‘Item 1. Business - Risk Management Activities’’ for more information. Risks Related to Laws, Regulations and Litigation Our future efforts to sell shares or raise additional capital may be delayed or prohibited by regulations. As certain of our subsidiaries are members of FINRA, we are subject to certain regulations regarding changes in control of our ownership. FINRA Rule 1017 generally provides that FINRA approval must be obtained in connection with any transaction resulting in a change in control of a member firm. FINRA defines control as ownership of 25% or more of the firm’s equity by a single entity or person and would include a change in control of a parent company. Interactive Brokers Canada, Inc., Interactive Brokers (U.K.) Limited, Interactive Brokers Ireland Limited, IBKR Financial Services AG, Interactive Brokers Central Europe Zrt., Interactive Brokers Hong Kong Limited, and Interactive Brokers Singapore Pte. Ltd. are subject to similar change in control regulations promulgated by the CIRO in Canada, the FCA in the United Kingdom, the CBI in Ireland, the FINMA in Switzerland, the MNB in Hungary, the SFC in Hong Kong, and the MAS in Singapore, respectively. As a result of these regulations, our future efforts to sell shares or raise additional capital may be delayed or prohibited. We may be subject to similar restrictions in other jurisdictions in which we operate. Regulatory and legal uncertainties could harm our business. The securities and derivatives businesses are heavily regulated. Firms in financial service industries have been subject to an increasingly regulated environment over recent years, and penalties and fines sought by regulatory authorities have increased accordingly. Our broker-dealer subsidiaries are subject to regulations in the U.S. and abroad covering all aspects of their business. Regulatory bodies include, in the U.S., the SEC, FINRA, the Board of Governors of the Federal Reserve System, the Chicago Board Options Exchange, the CME, the CFTC, and the NFA; in Canada, the CIRO and various Canadian securities commissions; in the United Kingdom, the FCA; in Ireland, the CBI; in Switzerland, the FINMA; in Hungary, the MNB; in India, the Securities and Exchange Board of India; in Hong Kong, the SFC; in Japan, the Financial Supervisory Agency and the Japan Securities Dealers Association; in Singapore, the MAS; and in Australia, the Australian Securities and Investment Commission. Our mode of operation and profitability may be directly affected by additional legislation changes in rules promulgated by various domestic and foreign government agencies and self-regulatory organizations that oversee our businesses, and changes in the interpretation or enforcement of existing laws and rules, including the potential imposition of transaction taxes. Noncompliance with applicable laws or regulations could result in sanctions being levied against us, including fines and censures, suspension or expulsion from a certain jurisdiction or market or the revocation or limitation of licenses. Noncompliance with applicable laws or regulations could adversely affect our reputation, prospects, revenues and earnings. In addition, changes in current laws or regulations or in governmental policies could adversely affect our business, financial condition and results of operations. Domestic and foreign stock exchanges, other self-regulatory organizations and state and foreign securities commissions can censure, fine, issue cease-and-desist orders, suspend or expel a broker-dealer or any of its officers or employees. Our ability to comply with all applicable laws and rules is largely dependent on our internal systems to ensure compliance, as well as our ability to attract and retain qualified compliance personnel. We could be subject to disciplinary or other actions in the future due to claimed noncompliance, which could have a material adverse effect on our business, financial condition and results of operations. To continue to operate and to expand our services internationally, we may have to comply with the regulatory controls of each 30 country in which we conduct, or intend to conduct business, the requirements of which may not be clearly defined. The varying compliance requirements of these different regulatory jurisdictions, which are often unclear, may limit our ability to continue existing international operations and further expand internationally. We are subject to risks relating to litigation and potential securities laws liability. We are exposed to substantial risks of liability under federal and state securities laws, other federal and state laws and court decisions, as well as rules and regulations promulgated by the SEC, the CFTC, the Federal Reserve, state securities regulators, self-regulatory organizations and foreign regulatory agencies. We are also subject to the risk of litigation and claims that may be without merit. We could incur significant legal expenses in defending ourselves against and resolving lawsuits or claims. An adverse resolution of any future lawsuits or claims against us could result in a negative perception of the Company and have a material adverse effect on our business, financial condition and results of operations. See ‘‘Legal Proceedings and Regulatory Matters’’ in Part I Item 3 of this Annual Report on Form 10 K. Heightened regulatory and legislative requirements in the U.S. and internationally have increased our compliance, regulatory and other risks and costs. We are required to interpret and implement extensive and frequently changing regulatory and legislative requirements in the U.S. and other jurisdictions in which we do business resulting in substantial compliance, regulatory and other risks and costs, including the hiring of additional personnel. In addition, there is heightened regulatory scrutiny and expectations in the U.S. and internationally with respect to governance, infrastructure, data, risk management practices and controls. A failure to comply with these requirements and expectations, even if inadvertent, or resolve any identified deficiencies, could result in increased regulatory oversight and restrictions, enforcement proceedings, penalties and fines. We may incur additional tax expense or become subject to additional tax liabilities. We are subject to the tax laws and regulations of the U.S. and its states and municipalities, as well as numerous foreign jurisdictions in which we do business. These laws, regulations and treaties are complex, and the manner they apply to us is sometimes open to interpretations, therefore significant judgments are required in determining our provision for income taxes, deferred tax assets and liabilities balances, and other tax liabilities. We are also regularly under audit by the U.S. Internal Revenue Service and other tax authorities, both in the U.S. and abroad, which may not agree with our tax positions and cause our tax liabilities to increase. In addition, our tax liabilities are subject to other significant risks and uncertainties, including those arising from potential changes in laws and regulations in the countries in which we do business (e.g., on December 15, 2022, the EU formally adopted the EU’s Pillar Two Directive, effective January 1, 2024, which provides for a minimum effective tax rate of 15%, as established by the Organization for Economic Cooperation and Development (‘‘OECD’’) Pillar Two Framework; and a significant number of other countries have either already or are expected to also implement similar legislation with varying effective dates), the possibility of tax controversy related to adverse determinations with respect to the application of existing laws, changes in our business or structure, and changes in the valuation of our deferred tax assets and liabilities. Any unfavorable resolution of these and other uncertainties may have a significant adverse impact on our effective tax rate and results of operations. If our tax expense were to increase, or if the ultimate determination of our taxes owed is for an amount in excess of the amounts previously accrued, it could have a material adverse effect on our business, financial condition, cash flows, and results of operations. Risks Related to Our Intellectual Property, Technology, Cybersecurity and Data Privacy We may not be able to protect our intellectual property rights or may be prevented from using intellectual property necessary for our business. We rely primarily on trade secret, contract, copyright, patent and trademark laws to protect our proprietary technology. It is possible that third parties may copy or otherwise obtain and use our proprietary technology without authorization or otherwise infringe on our rights. We may also face claims of infringement that could interfere with our ability to use technology that is material to our business operations. 31 In the future, we may have to rely on litigation to enforce our intellectual property rights, protect our trade secrets, determine the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. Any such litigation, whether successful or unsuccessful, could result in substantial costs and the diversion of resources and the attention of management, any of which could negatively affect our business. Our reliance on our computer software could cause us great financial harm in the event of any disruption or corruption of our computer software. We may experience technology failures while developing our software. We rely on our computer software to receive and properly process internal and external data. Any disruption in the proper functioning of our software due to, for example, erroneous or corrupted data, or cyber-attacks, may cause us to make erroneous trades or suspend our services and could cause us great financial harm. To maintain our competitive advantage, our software is under continuous development. As we identify and enhance our software, there is risk that software failures may occur and result in service interruptions and have other unintended consequences. We depend on our proprietary technology, and our future results may be impacted if we cannot maintain technological superiority in our industry. Our success in the past has largely been attributable to our sophisticated proprietary technology that has taken many years to develop. We have benefited from the fact that the type of proprietary technology equivalent to that which we employ has not been widely available to our competitors. If our technology becomes more widely available to our current or future competitors for any reason, our operating results may be adversely affected. Additionally, adoption or development of similar or more advanced technologies by our competitors may require that we devote substantial resources to the development of more advanced technology to remain competitive. The markets in which we compete are characterized by rapidly changing technology, evolving industry standards and changing trading systems, practices and techniques. Although we have been at the forefront of many of these developments in the past, we may not be able to keep up with these rapid changes in the future, develop new technology, realize a return on amounts invested in developing new technologies or remain competitive in the future. New developments in the field of Artificial Intelligence (‘‘AI’’) could enable competitors to offer new products or services never before seen in the marketplace. While we strive to provide the most cutting-edge technology to our customers, breakthroughs or significant innovations made using AI (or discoveries uncovered through the use of AI) could change the nature of our business. Competitors who advance in this space may be able to offer superior products and services and may materially adversely affect our business, financial condition and results of operations. We do not have fully redundant systems. System failures could harm our business. If our systems fail to perform, we could experience unanticipated disruptions in operations, slower response times or decreased customer service and customer satisfaction. Our ability to facilitate transactions successfully and provide high quality customer service also depends on the efficient and uninterrupted operation of our computer and communications hardware and software systems. Our service has experienced periodic system interruptions, which we believe will continue to occur from time to time. Our systems and operations are also potentially vulnerable to damage or interruption from human error, cyber-attacks, natural disasters, power loss, telecommunication failures, break-ins, sabotage, computer viruses, intentional acts of vandalism and similar events. We do not have fully redundant systems, and our formal business continuity plan does not include restoration of all services. We currently have limited separate backup facilities dedicated to our non-U.S. operations. It is our intention to provide for and progressively deploy backup facilities for all facilities and infrastructure globally over time. In addition, we do not carry business interruption insurance to compensate for losses that could occur to the extent not required. Any system failure that causes an interruption in our service or decreases the responsiveness of our service could impair our reputation, damage our brand name and materially adversely affect our business, financial condition and results of operations. 32 Failure of third-party systems on which we rely could adversely affect our business. We rely on certain third-party computer systems or third-party service providers, including clearing systems, exchange systems, banking systems, cryptocurrency systems, Internet services, third-party identity verification services, co-location facilities, communications facilities and other facilities. Any interruption in these third-party services, or deterioration in their performance, could be disruptive to our business. If our arrangement with any third party is terminated, we may not be able to find an alternative source of systems support on a timely basis or on commercially reasonable terms. This could have a material adverse effect on our business, financial condition and results of operations. Internet-related issues may reduce or slow the growth in the use of our services in the future. Our ability to provide services to consumers and increase the scope and quality of such services is limited by and dependent upon the speed and reliability of our customers’ unrestricted access to the Internet, which is beyond our control. If periods of decreased performance, outages or delays on the Internet occur frequently, growth in the usage of our web-based products could be delayed or decline, which could have a material adverse effect on our business, financial condition and results of operations. We could be the target of a cyber-attack or experience a cybersecurity incident that impairs internal systems, degrades services we provide to customers, or results in a data compromise, causing reputational or monetary damages as a consequence. Our business relies on technology and automation, causing us to be potentially vulnerable to various forms of cyber-attacks by external actors or malicious insiders. Any resulting security breaches could expose us to liability to one or more third parties, including our customers, and disrupt our operations. Though we take steps to mitigate the various cyber threats and devote resources to protecting our systems and networks, we may be unable to anticipate all types of attacks or to implement adequate preventative measures against all eventualities. Our cybersecurity measures may not detect or prevent all attempts to compromise our systems. Furthermore, whereas we expend efforts on evaluating and ensuring adequacy of security measures employed by third-party service providers, we may not be able to exercise full control over them. Failures or deficiencies of such controls could result in adverse impacts to our business, operations, or confidential information, depending on the nature of the services provided. Breaches of our cybersecurity measures or those of our third-party service providers could result in any of the following: unauthorized access to our systems; unauthorized access to and misappropriation of information or data, including confidential or proprietary information about ourselves, third parties with whom we do business or our proprietary systems; viruses, worms, spyware, ransomware, or other malware being placed in our systems; misappropriation, deletion or modification of customer information; or a denial-of-service or other interruptions to our business operations. To the extent that our activities involve the storage and transmission of proprietary information such as personal financial information, security breaches could expose us to a risk of financial loss, litigation and other liabilities. Any of these events, particularly if they (individually or in the aggregate) result in a loss of confidence in our company or electronic brokerage firms in general, could have a material adverse effect on our business, financial condition and results of operations. We are subject to stringent and complex data privacy rules. Failure to comply with these rules could expose us to a risk of financial loss, litigation, and other liabilities. We are subject to numerous data privacy rules, including federal, state, local and international laws, as well as industry standards and regulations, and contractual obligations relating to data privacy and the collection, protection, use, retention, security, disclosure, transfer, and other processing of personal and other data. In the U.S., we are subject to rules including the Gramm-Leach-Bliley Act of 1999 and Section 5(c) of the Federal Trade Commission Act; internationally, we are subject to the EU’s General Data Protection Regulation (‘‘GDPR’’), the Data Protection Act 2018 in the U.K, the Personal Information Protection Law of the People’s Republic of China, and other data privacy rules. We continue our efforts to safeguard the data entrusted to us in accordance with applicable laws and our data protection policies, including taking steps to reduce the potential for the improper use or disclosure of personal data; and continue to monitor regulations related to data privacy on both a domestic and international level to assess requirements and impacts on our business operations. 33 Rules regarding data privacy and security worldwide are continuously evolving and developing, increasing complexity and, as a result, interpretation and implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future. New laws, amendments to or reinterpretations of existing laws, regulations, standards, and other obligations might require us to incur additional costs and change how we use, collect, store, transfer or otherwise process certain types of personal data, to implement new processes to comply with those laws and our customers’ exercise of their rights thereunder. If we fail to follow these security standards, even if no customer information is compromised, we might incur significant fines or experience a significant increase in costs. Any failure or perceived failure by us or our third-party service providers to comply with our privacy policies or any applicable laws, regulations, industry standards, or rules relating to data privacy and security, or any compromise of security that results in the theft, unauthorized access, acquisition, use, disclosure, or misappropriation of personal data, could result in significant fines, criminal penalties, monetary damages, regulatory enforcement actions, litigation and reputational harm, one or all of which could have an adverse effect on our business, financial condition and results of operations. Risks Related to our Cryptocurrency Offering We rely on third-party Cryptocurrency Service Providers (‘‘CSPs’’) to provide our customers the ability to access cryptocurrency trading and custody services. We have entered into agreements with third-party CSPs, which provide (i) cryptocurrency exchange platforms and services whereby investors can buy and sell certain cryptocurrencies and (ii) custody services for certain cryptocurrencies (collectively, the ‘‘Exchange Services’’), enabling some of our customers to trade and custody Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH) and potentially other cryptocurrencies, (collectively, ‘‘Cryptocurrency Assets’’) via CSPs. A disruption in our partnership with a CSP or in the Exchange Services provided by a CSP could have adverse effects on our customers’ confidence in our cryptocurrency offering through CSPs and on our business. A data breach at the CSPs may result in irreversible losses, which would adversely affect our customers and our business. The CSPs are responsible for securing the customers’ Cryptocurrency Assets and protecting them from loss or theft. Access to the Cryptocurrency Assets is controllable only by the possessor of the unique private key(s) relating to the digital wallet in which such Cryptocurrency Assets are held. To the extent any of the CSPs’ private keys are lost, destroyed, unable to be accessed by the CSPs, or otherwise compromised and no backup of such private key(s) is accessible, the CSPs may be unable to access the Cryptocurrency Assets held in the respective wallets. In addition, neither the CSPs nor any cryptocurrency custodian can provide absolute assurance that any or all of the CSPs’ wallets will not be hacked or compromised such that the private keys are obtained by a third party or otherwise compromised in a manner such that Cryptocurrency Assets are sent to one or more addresses that the CSPs do not control, which could result in the loss of some or all of the Cryptocurrency Assets that the CSPs hold in custody on behalf of our customers. Eligible customers of IB LLC can enroll to access a digital asset exchange and custody services provided by one or more CSPs to buy, sell and hold Cryptocurrency Assets in an account in the customer’s name at the CSP. IB LLC does not provide execution, custody or safeguarding services for the customers’ Cryptocurrency Assets and does not maintain (or have access to) the cryptographic key information and wallets necessary to access the Cryptocurrency Assets, nor does IB LLC have any legal title or claim to those Cryptocurrency Assets. The agreement the customer signs with IB LLC before the customer is permitted to access the CSP’s services through IB LLC’s platform provides that: [Customer] acknowledges and agrees that [IB LLC] is not responsible for any trading or other losses (including, without limitation, losses due to theft, fraud, cybersecurity breach, loss of control of private keys, or any other loss arising from trading or holding digital assets with [the CSP]) resulting directly or indirectly from or in connection with [Customer’s] relationship with [the CSP] and/or [Customer’s] trading or holding of digital assets, including activity or holdings in the [CSP] Account. 34 Eligible customers of IBHK can enroll to trade and hold Cryptocurrency Assets through a relationship IBHK has established with a CSP, which is an SFC-licensed digital asset exchange and custodian. The Cryptocurrency Assets are sub-custodied by the CSP on an omnibus basis for the benefit of the customers of IBHK. IBHK notifies its customers that exchange and sub-custody services are provided by a CSP. IBHK does not maintain (or have access to) the cryptographic key information and wallets necessary to access the Cryptocurrency Assets, nor does IBHK have any beneficial claim to those Cryptocurrency Assets. The CSP is responsible for securing the customers’ Cryptocurrency Assets and protecting them from loss or theft, and the SFC requires the CSP to maintain adequate controls and insurance against the risk of theft or loss of the customers’ Cryptocurrency Assets. The agreement the customer signs with IBHK before the customer is permitted to access digital asset trading provides that: To the maximum extent permitted by applicable Rules, [IBHK] is not liable to [Customer] for loss arising from or attributable to the insolvency of any [CSP], in the event of hacking or otherwise caused by the default of the [CSP], where [IBHK] has not failed to exercise reasonable care and diligence in the selection, appointment and ongoing monitoring of the [CSP], except (i) such loss arising from the gross negligence, willful default or fraud of [IBHK], or (ii) to the extent prohibited under applicable Rules. Notwithstanding any other provision of these Terms, in the absence of either (a) a failure by [IBHK] to exercise reasonable care and diligence in the selection, appointment and ongoing monitoring of the [CSP], or (b) gross negligence, wilful default or fraud on the part of [IBHK], [IBHK] will only be obliged to return Virtual Assets held for [Customer] with the [CSP] who is insolvent, or which Virtual Assets have otherwise been subjected to loss due to an event of hacking, embezzlement, or theft at the [CSP] or which losses are otherwise caused by the default of the [CSP], solely if and to the extent that those Virtual Assets or equivalent value are recovered by [IBHK] from the [CSP]. Unless otherwise provided under applicable Rules, [Customer] hereby agree[s] not to bring any action against [IBHK] on any claim arising from a loss occurring at the [CSP], in the absence of circumstances addressed under (a) or (b) above, so long as [IBHK] makes commercially reasonable efforts to assert a claim for recovery against the [CSP]. The CSPs’ failure to safeguard the Cryptocurrency Assets may result in losses to our customers which could have adverse effects on our customers’ confidence in our cryptocurrency offering through CSPs and on our business. We may encounter technical issues which would result in disruption or interruption of our customers’ access to their CSP accounts. Both we and the CSPs rely on computer software, hardware and telecommunications infrastructure and networking to provide the respective services to our customers with respect to trading and custody of the Cryptocurrency Assets. These computer-based systems and services are inherently vulnerable to disruption, delay, or failure, which may cause our customers to lose access to our trading platform and the Exchange Services provided by the CSPs. Any such disruption could have an adverse effect on our customers’ confidence in our cryptocurrency offering through the CSPs and an adverse effect on our business. Changes in laws and regulations regarding cryptocurrency may negatively impact our ability to enable our customers to buy, hold and sell cryptocurrencies in the future and may adversely affect our business. Regulation of the cryptocurrency industry continues to evolve and is subject to change. Securities and commodities laws and regulations and other bodies of laws can apply to certain cryptocurrency assets. These laws and regulations are complex and the interpretations of them may be subject to challenge by the relevant regulators. Future regulatory developments, including the treatment of certain cryptocurrency assets for U.S. federal income tax and foreign tax purposes, could have an adverse effect on our cryptocurrency offering through CSPs and on our business. A loss event incurred by a CSP may adversely impact our operating results. In March 2022, the SEC published Staff Accounting Bulletin No. 121 (‘‘SAB 121’’), which provides interpretive accounting and disclosure guidance to entities that have obligations to safeguard crypto-assets held for their platform users, whether directly or through an agent or another third party acting on its behalf. SAB 121 requires an entity to recognize a liability to reflect its obligation to safeguard the crypto-assets held for its platform users and a corresponding safeguarding asset on its balance sheet, even when the entity does not control the crypto-assets. 35 Even though we are not responsible for the safeguarding of crypto-assets at the CSPs, our customers’ crypto-assets held at the CSPs are deemed to be in scope of SAB 121. Pursuant to SAB 121, we measure the crypto-asset safeguarding liability and the corresponding safeguarding asset at the fair value of the crypto-assets held by the CSPs for our customers. Because, under the guidance, the measurement of the safeguarding asset shall take into account any potential loss events, if a CSP were to suffer a loss event that impacted our customers’ crypto-assets held by that CSP, then (subject to consultation with the SEC’s Office of the Chief Accountant) we may be required to recognize a reduction in the value of the safeguarding asset at the time of the CSP’s loss event, without recognizing a corresponding reduction in the value of the safeguarding liability, even though we have no legal obligation to our customers with respect to the crypto-assets held by the CSPs. The recognition of such loss event could have a material adverse effect on our results of operations. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 1C. CYBERSECURITY As part of our overall risk management framework, we have processes in place to identify, assess, and manage material risks from cybersecurity threats. Cybersecurity Program Overview Our cybersecurity program is designed to identify, assess, and manage cyber risks. The program involves risk assessments, implementation of security measures, and ongoing monitoring of systems and networks. We continually evaluate the current threat landscape in an effort to identify material risks arising from new and evolving cybersecurity threats. We engage external experts, including cybersecurity assessors, consultants, and auditors to evaluate cybersecurity measures and risk management processes. Where we engage or rely on third parties, including suppliers, vendors, and service providers, our information security personnel have processes in place to identify and manage risks from cybersecurity threats associated with our use of such third parties. Board Oversight of Cybersecurity Risks Our Board of Directors receives periodic updates on cybersecurity matters from our Chief Executive Officer (based on consultation with our Chief Information Security Officer (‘‘CISO’’) and other senior members of our Information Security and/or Technology teams). In addition, a member of senior management responsible for the Company’s Information Security team provides an annual briefing to our Board of Directors regarding the overall state of our cybersecurity program, information on the current cybersecurity threat landscape, risks from cybersecurity threats and any cybersecurity incidents that are reasonably likely to materially affect, or which have materially affected, the Company. Management’s Role in Cybersecurity Risk Management The Company’s management, including the Company’s Chief Information Officer, Executive Vice President of Technology, and CISO, are responsible for assessing and managing material risks from cybersecurity threats. Members of Company management possess relevant expertise in various disciplines that are key to effectively managing such risks. Specifically: • Dr. Thomas Frank, Executive Vice President and Chief Information Officer: Dr. Frank has been with the Company since 1985 and was instrumental in the development of the Company’s early market making systems. Dr. Frank became Chief Information Officer in 2006. Dr. Frank is responsible for the Company’s technical infrastructure and operations and information security, among other duties. Dr. Frank is a member of the Board of Directors of OCC. Dr. Frank received an S.B. and a Ph.D. in Physics from the Massachusetts Institute of Technology. 36 • • Somayajulu (Soma) Bulusu, Executive Vice President of Technology: Mr. Bulusu joined the Company as EVP of Technology in February 2024. Mr. Bulusu has over 25 years of experience in engineering, product, and service delivery. Mr. Bulusu joined the Company from Chewy, Inc., where he led the Information Technology and Engineering teams. His previous roles include leadership positions at Amazon, Nuance, and TouchCommerce. Dr. Boris Kogan, Chief Information Security Officer: Dr. Kogan has served as the Company’s Chief Information Security Officer since 2016. Dr. Kogan has over 20 years of cybersecurity management experience in the financial services sector. Earlier in his career, after obtaining a Ph.D. in Computer Science from Princeton University, Dr. Kogan served on the faculty of George Mason University, where he conducted government-sponsored research in cybersecurity. The Company’s management, including through its oversight of the Company’s policies and procedures regarding cybersecurity, is actively involved in the prevention, detection, mitigation, and remediation of cybersecurity incidents impacting the Company. Management’s oversight is augmented through the Company’s Enterprise Risk Management Framework, which includes risk and control assessments related to the Company’s cybersecurity program. Additionally, the Company’s Internal Audit Group periodically audits aspects of the Company’s cybersecurity program and provides reports to the Board’s Audit Committee, and an external audit firm conducts an annual SOC 2 attestation of the Company’s information security controls. Assessment of Cybersecurity Risk The potential impact of risks from cybersecurity threats to the Company is assessed on an ongoing basis. During the reporting period and through the issuance of this Annual Report on Form 10-K, the Company has not identified any risks from cybersecurity threats, including as a result of previous cybersecurity incidents, that the Company believes have materially affected, or are reasonably likely to materially affect, the Company, including its business strategy, operational results, and financial condition. For additional information about cybersecurity risks, see Part I, Item 1A, ‘‘Risk Factors’’ in this Annual Report on Form 10-K. 37 ITEM 2.

LEGAL PROCEEDINGS AND REGULATORY MATTERS The securities and commodities industry is highly regulated and many aspects of our business involve substantial risk of liability. In past years, there has been an increasing incidence of litigation involving the brokerage industry, including class action suits that generally seek substantial damages, including in some cases punitive damages. Compliance and trading problems that are reported to federal, state and provincial regulators, exchanges or other self-regulatory organizations by dissatisfied customers are investigated by such regulatory bodies, and, if pursued by such regulatory body or such customers, may rise to the level of arbitration or disciplinary action. We are also subject to periodic regulatory audits and inspections. Like other brokerage firms, we have been named as a defendant in lawsuits and from time to time we have been threatened with, or named as a defendant in arbitrations and administrative proceedings. We may in the future become involved in additional litigation or regulatory proceedings in the ordinary course of our business, including litigation or regulatory proceedings that could be material to our business. For more information regarding pending and threatened legal actions and proceedings see Note 14 - ‘‘Commitments, Contingencies, and Guarantees’’ to the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K. Pending Regulatory Inquiries Our businesses are heavily regulated by state, federal and foreign regulatory agencies as well as numerous exchanges and self-regulatory organizations. Most of our companies are regulated under some or all of the following: state securities laws, U.S. and foreign securities, commodities and financial services laws and the rules of the more than 150 exchanges, market centers and self-regulatory organizations of which one or more of our companies may be members. In the current era of heightened regulatory scrutiny of financial institutions, we have incurred increased compliance costs, along with the industry as a whole. Increased regulation also creates increased barriers to entry. We have built and continue to build human and automated infrastructure in light of increasing regulatory scrutiny, which provides us with a possible advantage over potential newcomers to the business. We receive many regulatory inquiries each year in addition to being subject to frequent regulatory examinations. The great majority of these inquiries do not lead to fines or any further action against us. We are generally the subject of regulatory inquiries regarding subjects including, but not limited to: audit trail reporting, trade reporting, best execution and order execution procedures, display of market data, short sales, margin lending, exchange fees charged to customers, anti-money laundering or potentially manipulative trading by customers, sanctions compliance, procedures for accounts managed by independent financial advisors or referred by third parties, technology development practices, registration, record-keeping, business continuity planning, cybersecurity and other topics of recent regulatory interest. The Company has procedures for evaluating whether potential regulatory fines are probable, estimable and material and for updating its contingency reserves and disclosures accordingly. In the current climate, we expect to pay significant and increasing regulatory fines on various topics on an ongoing basis, as other regulated financial services businesses do. The amount of any fines, and when and if they will be incurred, typically is impossible to predict given the nature of the regulatory process. ITEM 4. MINE SAFETY DISCLOSURES Not applicable. 39 PART II ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY; RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Common Stock Information Interactive Brokers Group Inc.’s Class A common stock trades under the symbol ‘‘IBKR’’ on Nasdaq. As of February 20, 2024, there were 35 holders of record, which does not reflect those shares held beneficially or those shares held in ‘‘street’’ name. Accordingly, the number of beneficial owners of our common stock exceeds this number. Dividends and Other Restrictions We currently intend to pay quarterly dividends of $0.10 per share to our common stockholders for the foreseeable future.

From 2019 through 2023, the Company issued 420,000 shares and an additional 50,000 shares in January 2024 to IBG LLC for distribution to eligible customers of certain of its subsidiaries. On July 27, 2023, the Company filed a Prospectus Supplement on Form 424B5 (File Number 333-273451) with the SEC to issue 2,632,748 shares of common stock (with a fair value of $229 million) in exchange for an equivalent number of shares of member interests in IBG LLC. As a consequence of these redemption transactions, and distribution of shares to employees, IBG, Inc.’s interest in IBG LLC has increased to approximately 25.4%, with Holdings owning the remaining 74.6% as of December 31, 2023. The redemptions also resulted in an increase in the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 84.6% at the IPO to approximately 91.3% as of December 31, 2023. See Note 4 – ‘‘Equity and Earnings per Share’’ and Note 10 – ‘‘Employee Incentive Plans’’ to the financial statements in Part II, Item 8 of this Annual Report on Form 10-K.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the audited consolidated financial statements and the related notes in Part II, Item 8, of this Annual Report on Form 10-K. In addition to historical information, the following discussion also contains forward-looking statements that include risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under the heading ‘‘Risk Factors’’ in Part I, Item 1A of this Annual Report on Form 10-K. Business Overview We are an automated global electronic broker. We custody and service accounts for hedge and mutual funds, ETFs, registered investment advisers, proprietary trading groups, introducing brokers and individual investors. We specialize in routing orders and executing and processing trades in stocks, options, futures, forex, bonds, mutual funds, ETFs and precious metals on more than 150 electronic exchanges and market centers in 34 countries and 27 currencies seamlessly around the world. In addition, our customers can use our trading platform to trade certain cryptocurrencies through third-party cryptocurrency service providers that execute, clear and custody the cryptocurrencies. As an electronic broker, we execute, clear and settle trades globally for both institutional and individual customers. Capitalizing on our proprietary technology, our systems provide our customers with the capability to monitor multiple markets around the world simultaneously and to execute trades electronically in these markets at a low cost, in multiple products and currencies from a single trading account. The ever-growing complexity of multiple market centers across diverse geographies provides us with ongoing opportunities to build and continuously adapt our order routing software to secure excellent execution prices. Since our inception in 1977, we have focused on developing proprietary software to automate broker-dealer functions. The proliferation of electronic exchanges and market centers has allowed us to integrate our software with an increasing number of trading venues, creating one automatically functioning, computerized platform that requires minimal human intervention. Our customer base is diverse with respect to geography and type. Currently, approximately 81% of our customers reside outside the U.S. in over 200 countries and territories, and over 80% of new customers come from outside the U.S. Approximately 57% of our customers’ equity is in institutional accounts such as hedge funds, financial advisors, proprietary trading firms and introducing brokers. Specialized products and services that we have developed successfully attract these accounts. For example, we offer prime brokerage services, including financing and securities lending, to hedge funds; our model portfolio technology and automated share allocation and rebalancing tools are particularly attractive to financial advisors; and our trading platform, global access and low pricing attract introducing brokers. Business Environment In 2023, most world equities markets, including the U.S., Europe, Japan and Australia, reached all-time highs (one notable exception was Hong Kong, which was down on the year). Elevated inflation, and the tighter monetary policy and resulting higher interest rates deployed to fight it, led to recession fears early in the year. In the second half, however, the expectation of lower interest rates and a ‘‘soft landing’’ for global economies drove markets higher, despite the ongoing backdrop of geopolitical uncertainty. Individual investors, who helped drive equities market volumes higher in prior years, were more engaged in 2023 with the options markets and less so in equities markets. The following is a summary of the key economic drivers that affect our business and how they compared to the prior-year quarter: Global trading volumes. Worldwide, equities volumes at most major exchanges declined in the current year, while major market indexes reached all-time highs. Within U.S. equities, a small number of technology stocks (the so-called ‘‘Magnificent 7’’) were responsible for a large portion of market index gains during the year. While stock trading volumes remained higher than pre-pandemic levels, they were lower in the current year versus a year ago as investors chose to maintain their holdings in these technology stocks. In the U.S., according to industry data, average daily volume in exchange-listed equity-based options increased by 8% and futures by 42 5%, while listed cash equities volume decreased by 7%, compared to 2022. Options trading volumes have risen with the growing popularity of shorter-dated options contracts, while in futures, market volumes increased in agriculture, interest rate, metals and energy products, in part as investors sought to mitigate exposure to persistent inflation, higher interest rates and geopolitical uncertainties. These factors led to mixed results across our major product types. Our customer options and futures volumes were up 12% and 1%, respectively, while stock and foreign exchange volumes declined 24% and 29%, respectively, compared to the prior year. Note that while U.S. options, futures and cash equities volumes are readily comparable measures, they reflect most but not all of the global volumes that generate our commission revenue. See ‘‘Trading Volumes and Customer Statistics’’ below in this Item 7 for additional details regarding our trade volumes, contract and share volumes, and customer statistics. Volatility. U.S. market volatility, as measured by the average Chicago Board Options Exchange Volatility Index (‘‘VIX®’’), declined 35%, from an average of 26.0 in 2022 to 16.8 in the current year. Volatility levels had been elevated for most of 2022 in light of geopolitical events such as regional conflicts; more unpredictable world economies and markets; and consistent, significant interest rate hikes. In contrast, the current level of volatility has dipped below long-term trends. In particular, the current year did not exhibit the brief spikes in volatility that were more frequently seen in prior years. In general, higher volatility typically enhances our performance because it often correlates positively with customer trading activity across product types. Interest Rates. The U.S. Federal Reserve increased the benchmark federal funds rate four times in 2023, in February, March, May and July, which raised rates cumulatively by 100 basis points. The U.S. Treasury yield curve remained inverted, with long-term rates markedly lower than short-term. In most countries with developed financial markets, benchmark interest rates also rose over the year as central banks continued to take steps to control inflation. Higher U.S. benchmark rates have boosted the interest we earn on our segregated cash, the majority of which is invested in short-term U.S. government securities and related instruments. Higher short-term rates, and uncertainty over future U.S. Federal Reserve rate policy, have led us to maintain a short duration portfolio, all of which matured within three months at December 31, 2023, to more closely match our asset and liability maturities on our interest-sensitive assets. Further, our margin balances are tied to benchmark rates, so higher rates in 2023 have also improved the interest we earn on margin lending to our customers. We continue to offer among the lowest rates in the industry on margin lending, and we believe our low rates are an important feature that attracts customers to our platform. Rising rates also increase our interest expense. For example, in U.S. dollars we pay interest to customers on their qualified cash balances when the federal funds effective rate is above 0.50%, which it has been since May 2022. Central banks in many other countries have also increased their interest rates in recent months. We believe the attractive rates we pay on customer cash are among the highest in the industry and are another important feature that draws customers to our platform. Net interest income on customer cash and margin loan balances increased significantly compared to the prior year as the average federal funds effective rate increased to 5.03% in the current year from 1.68% in the prior year. During an extended period prior to and including part of 2022, the interest we paid on customer cash balances and earned on customer margin loans and investment of customer segregated funds resulted in spreads that were compressed at low benchmark rates. Now that benchmark interest rates are over 50 basis points and spread compression has been eliminated, we earn higher net interest income. Higher interest rates contributed to a 68% rise in net interest income over the prior year. Combined with increases in average interest-earning assets, particularly in segregated cash balances, these higher rates led to a widening of our net interest margin from 1.53% in the prior year to 2.36% in the current year. Currency fluctuations. As a global electronic broker trading on exchanges around the world in multiple currencies, we are exposed to foreign currency risk. We actively manage this exposure by keeping our equity in proportion to a defined basket of 10 currencies we call the ‘‘GLOBAL’’ to diversify our risk and to align our hedging strategy with the currencies that we use in our business. Because we report our financial results in 43 U.S. dollars, the change in the value of the GLOBAL versus the U.S. dollar affects our earnings. During the current year, the value of the GLOBAL, as measured in U.S. dollars, increased 0.41% compared to its value at December 31, 2022, which had a positive impact on our comprehensive earnings for the current year. A discussion of our approach for managing foreign currency exposure is contained in Part I, Item 7A of this Quarterly Report on Form 10-Q entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Financial Overview We report non-GAAP financial measures, which exclude certain items that may not be indicative of our core operating results and business outlook and are useful in evaluating the operating performance of our business. See the ‘‘Non-GAAP Financial Measures’’ section below in this Item 7 for additional details. Diluted earnings per share were $5.67 for the year ended December 31, 2023 (‘‘current year’’), compared to $3.75 for the year ended December 31, 2022 (‘‘prior year’’). Adjusted diluted earnings per share were $5.75 for the current year, compared to $4.05 for the prior year. The calculation of diluted earnings per share is detailed in Note 4 – ‘‘Equity and Earnings Per Share’’ to the audited consolidated financial statements, in Part II, Item 8 of this Annual Report on Form 10-K. For the current year, our net revenues were $4,340 million and income before income taxes was $3,069 million, compared to net revenues of $3,067 million and income before income taxes of $1,998 million in the prior year. Adjusted net revenues were $4,367 million and adjusted income before income taxes was $3,101 million, compared to adjusted net revenues of $3,213 million and adjusted income before income taxes of $2,144 million in the prior year. The financial highlights for the current year were: • • • • • • Net interest income increased 68% from the prior year to $2,794 million, driven by higher benchmark interest rates and customer credit balances. Commission revenue increased 3% from the prior year to $1,360 million on higher options and futures volumes, partially offset by lower customer stock trading volumes. Other fees and services increased 7% from the prior year to $197 million on higher risk exposure fees and Insured Bank Deposit Sweep Program fees (‘‘FDIC sweep fees’’). Other income increased $96 million from the prior year to a loss of $11 million. This increase was mainly comprised of (1) $20 million related to our currency diversification strategy, (2) $52 million related to our U.S. government securities portfolio, and (3) $25 million related to our strategic investment in Up Fintech Holding Limited (‘‘Tiger Brokers’’). Execution, clearing and distribution fees expenses increased 19% to $386 million, driven by higher customer trading volume in options and futures. Pretax profit margin was 71%, up from 65% in the prior year. Adjusted pretax profit margin was 71%, up from 67% in the prior year. In connection with our currency diversification strategy as of December 31, 2023, approximately 25% of our equity was denominated in currencies other than the U.S. dollar. In the current year, our currency diversification strategy increased our comprehensive earnings by $42 million (compared to a decrease of $211 million in the prior year), as the U.S. dollar value of the GLOBAL increased by approximately 0.41%, compared to its value as of December 31, 2022. The effects of our currency diversification strategy are reported as (1) a component of other income (loss of $80 million) in the consolidated statements of comprehensive income and (2) other comprehensive income (‘‘OCI’’) (gain of $122 million) in the consolidated statements of financial condition and the consolidated statements of comprehensive income. The full effect of the GLOBAL is captured in comprehensive income. 44 Certain Trends and Uncertainties We believe that our current operations may be favorably or unfavorably impacted by the following trends and uncertainties that may affect our financial condition and results of operations: • • • • • • • Retail participation in the equity markets has fluctuated in the past due to investor sentiment, market conditions and a variety of other factors. Retail transaction volumes may not be sustainable and are not predictable. Consolidation among market centers may adversely affect the value of our IB SmartRoutingSM software. Price competition among broker-dealers may continue to intensify. Benchmark interest rates tend to fluctuate with economic conditions. Changes in interest rates may not be predictable. Fiscal and/or monetary policy may change and impact the financial services business and securities markets. New legislation or modifications to existing regulations and rules could occur in the future. Scrutiny of payment for order flow and order routing practices by regulatory and legislative authorities has increased. The COVID-19 pandemic precipitated unprecedented market conditions with equally unprecedented social and community challenges. The impact of a public health emergency going forward will depend on numerous evolving factors that cannot be accurately predicted, including the duration and spread of the pandemic, governmental regulations in response to the pandemic, and the effectiveness of vaccinations and other medical advancements. • We continue to be exposed to the risks and uncertainties of doing business in international markets, particularly in the heavily regulated brokerage industry. Such risks and uncertainties include political, economic and financial instability, and foreign policy changes. For example, tensions between the U.S. and China have escalated in recent years, and changes in Chinese governmental oversight of Hong Kong and in the Chinese and Hong Kong capital markets could result in adverse effects on our business and loss of assets we hold in the region. Additionally, although our direct and indirect exposures to Russia and Ukraine are not material, the war in Ukraine and related sanctions have created substantial uncertainty in the global economy and financial markets. We continue to monitor the war and assess any potential impact to our business, including effects relating to currency control restrictions imposed by the Central Bank of Russia and restrictions by the Moscow Stock Exchange regarding the sale of assets by non-Russian residents. • Our remaining market making activities will continue to be impacted by market structure changes, market conditions, the level of automation of competitors, and the relationship between actual and implied volatility in the equities markets. See ‘‘Risk Factors’’ in Part I, Item 1A of this Annual Report on Form 10-K for a discussion of other risks that may affect our financial condition and results of operations. 45 Trading Volumes and Customer Statistics The tables below present historical trading volumes and customer statistics for our business.

The increase in net revenues was due to higher net interest income, commissions, other fees and services, and other income. Commissions We earn commissions from our cleared customers for whom we act as an executing and clearing broker and also from our non-cleared customers for whom we act as an execution-only broker. Our commission structure allows customers to choose between (1) an all-inclusive fixed, or ‘‘bundled’’, rate; (2) a tiered, or ‘‘unbundled’’, rate that offers lower commissions for high volume customers where we pass through regulatory and exchange fees; and (3) our IBKR LiteSM offering, which provides commission-free trades on U.S. exchange-listed stocks and ETFs. IBKR LiteSM trades generate payments from market makers and others to whom we route these orders, which are reported in commissions. Our commissions are geographically diversified. In 2023, 2022, and 2021 we generated 37%, 37% and 39%, respectively, of commissions from operations conducted by our subsidiaries outside the U.S. Commissions for the current year increased $38 million, or 3%, compared to the prior year, to $1,360 million, driven by higher customer trading volumes in options and futures, partially offset by lower customer trading volume in stocks. Total customer options and futures contract volumes increased 12% and 1%, respectively, while stock share volume decreased 24% from the prior year. Total DARTs for cleared and execution-only customers, for the current year, decreased 9% to 1.9 million, compared to 2.1 million for the prior year. DARTs 49 for cleared customers, i.e., customers for whom we execute trades, as well as clear and carry positions, for the current year, decreased 8% to 1.7 million, compared to 1.9 million for the prior year. Average commission per commissionable order for cleared customers, for the current year, increased 11% to $3.14, compared to $2.83 for the prior year, as our customers’ trading volume mix resulted in higher per order commissions across options, futures and stocks. Other Fees and Services We earn fee income on services provided to customers, which includes market data fees, risk exposure fees, payments for order flow from exchange-mandated programs, FDIC sweep fees, minimum activity fees, and other fees and services charged to customers. Other fees and services, for the current year increased $13 million, or 7%, compared to the prior year, to $197 million, driven by a $13 million increase in risk exposure fees as customers exhibited more risk-on behavior, and a $9 million increase in FDIC sweep fees due to higher benchmark interest rates and customer balances; partially offset by a $6 million decrease in market data fees and a $6 million decrease in payments for order flow. Other Income (Loss) Other income consists of foreign exchange gains (losses) from our currency diversification strategy, gains (losses) from principal transactions, gains (losses) from our equity method investments, and other revenue not directly attributable to our core business offerings. A discussion of our approach to managing foreign currency exposure is contained in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Other income, for the current year, increased $96 million, compared to the prior year, to a loss of $11 million. This increase was mainly comprised of $52 million from our U.S. government securities portfolio which gained $8 million in the current year compared to a $44 million loss in the prior year, $20 million related to our currency diversification strategy, and $25 million related to our strategic investment in Up Fintech Holding Limited (‘‘Tiger Brokers’’). Interest Income and Interest Expense We earn interest on margin lending to customers that is secured by marketable securities these customers hold with us; from our investments in U.S. and foreign government securities; from borrowing and lending securities; on deposits (in positive interest rate currencies) with banks; and on certain customers’ cash balances in negative rate currencies. We pay interest on customer cash balances (in sufficiently positive interest rate currencies); for borrowing and lending securities; on deposits (in negative interest rate currencies) with banks; and on our borrowings. Net interest income (interest income less interest expense), for the current year, increased $1,126 million, or 68%, compared to the prior year, to $2,794 million. The increase in net interest income was driven by higher benchmark interest rates and customer credit balances. Net interest income on customer balances, for the current year, increased $882 million, compared to the prior year, driven by an increase in the average federal funds effective rate to 5.02% from 1.68% in the prior year and a $5.9 billion increase in average customer credit balances. See the ‘‘Business Environment’’ section above in this Item 7 for a further discussion about the change in interest rates in the current year. The Company measures return on interest-earning assets using net interest margin (‘‘NIM’’). NIM is computed by dividing the annualized net interest income by the average interest-earning assets for the period. Interest-earning assets consist of cash and securities segregated for regulatory purposes (including U.S. government securities and securities purchased under agreements to resell), customer margin loans, securities borrowed, other interest-earning assets (solely firm assets) and customer cash balances swept into FDIC-insured banks as part of our Insured Bank Deposit Sweep Program. Interest-bearing liabilities consist of customer credit balances, securities loaned, and other interest-bearing liabilities. Yields are generally a reflection of benchmark interest rates in each currency in which the Company and its customers hold cash balances. Because a meaningful portion of customer cash and margin loans are denominated 50 in currencies other than the U.S. dollar, changes in U.S. benchmark interest rates do not impact the total amount of segregated cash and securities, customer margin loans and customer credit balances. Furthermore, because interest, when benchmark rates are at sufficiently high levels, is paid only on eligible cash credit balances (i.e., balances over $10 thousand or equivalent, in securities accounts with over $100 thousand in equity, and in smaller accounts at reduced rates), changes in benchmark interest rates are not passed through to the total amount of customer credit balances. Finally, the Company’s policies with respect to currencies with negative interest rates impact the overall yields on segregated cash and customer credit balances as effective interest rates in those currencies move above or below zero. We earn income on securities loaned and borrowed to support customer long and short stock holdings in margin accounts. A securities lending transaction generates (1) net interest earned on lending a security, which is based on supply and demand for that security, and (2) interest earned on the cash collateral deposited for the loan of that security, which is based on benchmark interest rates. Interest on this collateral is reported as net interest on segregated cash, since cash collateral from securities lending is held in specially-designated bank accounts for the benefit of customers, in accordance with U.S. customer protection rules. Generally, as benchmark interest rates rise, while the overall revenue generated from a securities lending transaction may not change, the portion derived from interest earned on the cash collateral, which is classified as net interest income on ‘‘Segregated cash and securities, net’’ increases, while the portion classified as ‘‘Securities borrowed and loaned, net’’ decreases. In the current year, average securities borrowed balances increased 34%, to $5.3 billion, and average securities loaned balances decreased 6%, to $9.5 billion, compared to the prior year. Net interest earned from securities lending is affected by the level of demand for securities positions held by our customers that investors are looking to sell short. During the current year, net interest earned from securities lending transactions decreased $137 million, or 33%, compared to the prior year. Despite generally lower demand for so-called ‘‘hard-to-borrow’’ stocks, we were able to capitalize on opportunities to lend certain high-rate stocks. However, as noted above, the rise in benchmark interest rates has shifted a portion of the interest reported as generated by lending securities to interest income on segregated cash (see further explanation above). It should be noted that securities lending transactions entered into to support customer activity may produce interest income (expense) that is offset by interest expense (income) related to customer balances. Our Stock Yield Enhancement Program provides an opportunity for customers with fully-paid stock to allow us to lend it out. We pay customers a rebate on the cash collateral generally equal to 50% of a market-based rate for lending the shares. We place cash and/or U.S. Treasury securities as collateral securing the loans in the customer’s account, which is held in segregated accounts, or at an affiliate acting as collateral agent for the benefit of our customer. 51 The table below presents net interest income information corresponding to interest-earning assets and interest-bearing liabilities for the periods indicated.

This item is not recorded in the Company’s consolidated statements of financial condition. Income derived from program deposits is reported in other net interest income in the table above. (2) (3) Interest income and interest expense on customer margin loans and customer credit balances, respectively, are calculated on daily cash balances within each customer’s account on a net basis, which may result in an offset of balances across multiple account segments (e.g., between securities and commodities segments). Includes income from financial instruments that has the same characteristics as interest, but is reported in other fees and services and other income in the Company’s consolidated statements of comprehensive income. For the years ended December 31, 2023, 2022, and 2021, $19 million, $10 million and $15 million were reported in other fees and services, respectively. For the years ended December 31, 2023, 2022, and 2021, $7 million, $4 million and $0 million were reported in other income, respectively. Non-Interest Expenses Non-interest expenses, for the current year, increased $202 million, or 19%, compared to the prior year, to $1,271 million, mainly due to a $73 million increase in employee compensation and benefits; a $62 million increase in execution, clearing and distribution fees; a $46 million increase in general and administrative expenses; a $9 million increase in occupancy, depreciation and amortization; and an $8 million increase in communications expenses. As a percentage of total net revenues, non-interest expenses were 29% for the current year and 35% for the prior year. 52 Execution, Clearing and Distribution Fees Execution, clearing and distribution fees include the costs of executing and clearing trades, net of liquidity rebates received from various exchanges and market centers, as well as regulatory fees and market data fees. Execution fees are paid primarily to electronic exchanges and market centers on which we trade. Clearing fees are paid to clearing houses and clearing agents. Market data fees, which are associated with market data revenue included in other fees and services, are paid to third parties to receive streaming price quotes and related information. Execution, clearing and distribution fees, for the current year, increased $62 million, or 19%, compared to the prior year, to $386 million, primarily driven by a $60 million increase in exchange fees on higher customer trading volumes in options and futures, which carry higher fees, and an $8 million increase in clearing and depository fees; partially offset by a $6 million decrease in regulatory fees on lower fee rates. As a percentage of total net revenues, execution, clearing and distribution fees were 9% for the current year and 11% for the prior year. Employee Compensation and Benefits Employee compensation and benefits include salaries, bonuses and other incentive compensation plans, group insurance, contributions to benefit programs and other related employee costs. Employee compensation and benefits expenses, for the current year, increased $73 million, or 16%, compared to the prior year, to $527 million, associated with a combination of staffing increases and inflation. The average number of employees increased 6% to 2,892 for the current year, compared to 2,721 for the prior year. We continued to add staff worldwide, primarily in software development and information technology services. As we continue to grow, our focus on automation has allowed us to maintain a relatively small staff. As a percentage of total net revenues, employee compensation and benefits expenses were 12% for the current year and 15% for the prior year. Employee compensation and benefits expenses as a percentage of adjusted net revenues were 12% for the current year and 14% for the prior year. Occupancy, Depreciation and Amortization Occupancy expenses consist primarily of rental payments on office and data center leases and related occupancy costs, such as utilities. Depreciation and amortization expenses result from the depreciation of fixed assets, such as computing and communications hardware, as well as amortization of leasehold improvements and capitalized in-house software development. Occupancy, depreciation and amortization expenses, for the current year, increased $9 million, or 10%, compared to the prior year, to $99 million, mainly due to higher costs related to the expansion of our physical space for both offices and data centers. As a percentage of total net revenues, occupancy, depreciation and amortization expenses were 2% for the current year and 3% for the prior year. Communications Communications expenses consist primarily of the cost of voice and data telecommunications lines supporting our business, including connectivity to exchanges and market centers around the world. Communications expenses, for the current year, increased $8 million, or 24%, compared to the prior year, to $41 million, mainly due to higher costs related to colocation sites and customer communications services. As a percentage of total net revenues, communications expenses were 1% for both the current year and the prior year. General and Administrative General and administrative expenses consist primarily of advertising; professional services expenses, such as legal and audit work; legal and regulatory matters; and other operating expenses. General and administrative expenses, for the current year, increased $46 million, or 28%, compared to the prior year, to $211 million, primarily due to the legal settlement with the SEC and CFTC of a regulatory investigation into the use of unapproved electronic messaging subject to record keeping requirements. As a percentage of total net revenues, general and administrative expenses were 5% for both the current year and the prior year. 53 Customer Bad Debt Customer bad debt expense consists primarily of losses incurred by customers in excess of their assets with us, net of amounts recovered by us. Customer bad debt expense, for the current year increased $4 million, or 133%, compared to the prior year, to $7 million. The current year expense includes a $5 million credit loss on a loan not related to margin lending. Income Tax Expense We pay U.S. federal, state and local income taxes on our taxable income, which is proportional to the percentage we own of IBG LLC. Also, our operating subsidiaries are subject to income tax in the respective jurisdictions in which they operate. Income tax expense, for the current year, increased $101 million, or 65%, compared to the prior year, to $257 million, primarily due to (1) higher income before income taxes at our operating subsidiaries outside the U.S. and (2) higher income before income taxes subject to U.S. income tax at IBG, Inc., additionally increased by IBG, Inc.’s higher average ownership percentage of IBG LLC, which rose from 24.0% to 25.0%.

Pretax profit margin was 71% for the current year and 65% for the prior year. Comparing our operating results for the current year to the prior year using non-GAAP financial measures, adjusted net revenues were $4,367 million, up 36%; adjusted income before income taxes was $3,101 million, up 45%; and adjusted pre-tax profit margin was 71% for the current year and 67% for the prior year. See the ‘‘Non-GAAP Financial Measures’’ section below in this Item 7 for additional details. 54 Noncontrolling Interest We are the sole managing member of IBG LLC and, as such, operate and control all of the business and affairs of IBG LLC and its subsidiaries and consolidate IBG LLC’s financial results into our financial statements. As of December 31, 2023, we held approximately 25.4% ownership interest in IBG LLC. Holdings holds approximately 74.6% ownership interest in IBG LLC. We reflect Holdings’ ownership as a noncontrolling interest in our consolidated statements of financial condition, consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows. Our share of IBG LLC’s net income, excluding Holdings’ noncontrolling interest, for the current year was approximately 25.0%, compared to approximately 24.0% for the prior year. Year Ended December 31, 2022 compared to the Year Ended December 31, 2021 For a discussion of changes for the year ended December 31, 2022 compared to the Year Ended December 31, 2021 refer to the Annual Report on Form 10-K filed with the SEC on February 24, 2023. 55 Non-GAAP Financial Measures We use certain non-GAAP financial measures as additional measures to enhance the understanding of our financial results. These non-GAAP financial measures include adjusted net revenues, adjusted income before income taxes, adjusted net income available for common stockholders, and adjusted diluted earnings per share (‘‘EPS’’). We believe that these non-GAAP financial measures are important measures of our financial performance because they exclude certain items that may not be indicative of our core operating results and business outlook. We believe these non-GAAP financial measures are useful to investors and analysts in evaluating the operating performance of the business. • We define adjusted net revenues as net revenues adjusted to remove the effect of our currency diversification strategy, our net mark-to-market gains (losses) on investments, and the remeasurement of our Tax Receivable Agreement (‘‘TRA’’) liability. • We define adjusted income before income taxes as income before income taxes adjusted to remove the effect of our currency diversification strategy, our net mark-to-market gains (losses) on investments, the remeasurement of our TRA liability, and unusual bad debt expense. • We define adjusted net income available to common stockholders as net income available for common stockholders adjusted to remove the after-tax effects attributable to IBG, Inc. of our currency diversification strategy, our net mark-to-market gains (losses) on investments, the remeasurement of our TRA liability, unusual bad debt expense, and the remeasurement of certain deferred tax assets. • We define adjusted diluted EPS as adjusted net income available for common stockholders divided by the diluted weighted average number of shares outstanding for the period. Mark-to-market on investments represents the net mark-to-market gains (losses) on investments in equity securities that do not qualify for equity method accounting which are measured at fair value, on our U.S. government and municipal securities portfolios, which are typically held to maturity, and on certain other investments, including equity securities taken over by the Company from customers related to unusual losses on margin loans. In the event an investment is sold prior to maturity, accumulated gains (losses) are realized and previously accumulated non-GAAP adjustments are reversed in the period of sale. Remeasurement of our TRA liability represents the change in the amount payable to IBG Holdings LLC under the TRA, primarily due to changes in the Company’s effective tax rates, which is related to the remeasurement of the deferred tax assets described below. For further information refer to Note 4 – Equity and Earnings per Share under Part II, Item 8 – Financial Statements and Supplementary Data of this Annual Report on Form 10-K. Unusual bad debt expense consists of a credit loss on a loan not related to margin lending. Remeasurement of certain deferred tax assets represents the change in the unamortized balance of deferred tax assets related to the step-up in basis arising from the acquisition of interests in IBG LLC, primarily due to changes in the Company’s effective tax rates. For further information refer to Note 4 – Equity and Earnings per Share under Part II, Item 8 – Financial Statements and Supplementary Data of this Annual Report on Form 10-K. We also report compensation and benefits expenses as a percent of adjusted net revenues, as we believe this measure is useful to investors and analysts in evaluating the growth of our work force in relation to the growth of our core revenues. These non-GAAP financial measures should be considered in addition to, rather than as a substitute for, measures of financial performance prepared in accordance with GAAP1. 1 Refers to generally accepted accounting principles in the United States. 56 The tables below present a reconciliation of consolidated GAAP to non-GAAP financial measures for the periods indicated.

The majority of our assets consist of investments of customer funds, collateralized receivables arising from customer-related and proprietary securities transactions, and exchange-listed marketable securities, which are marked-to-market daily. Collateralized receivables consist primarily of customer margin loans, securities borrowed, and securities purchased under agreements to resell. As of December 31, 2023, total assets were $128.4 billion of which approximately $127.2 billion, or 99.0%, were considered liquid. Decisions on the allocation of capital are based upon, among other things, prudent risk management guidelines, potential liquidity and cash flow needs for current and future business activities, regulatory capital requirements, and projected profitability. Our Treasury department, Market Risk Committee, Enterprise Risk Management department and other management control groups assist in evaluating, monitoring and controlling the impact that our business activities have on our financial condition, liquidity and capital structure. The objective of these policies is to support our business strategies while ensuring ongoing and sufficient liquidity. Our significant capital comprises an aggregate across our many regulated subsidiaries, and in addition to supporting our current and future expansion plans we believe this financial strength provides our customers with a source of confidence. Daily monitoring of liquidity needs and available collateral levels is undertaken to help ensure that an appropriate liquidity cushion, in the form of cash and unpledged collateral, is maintained at all times. We actively manage our excess liquidity and maintain significant borrowing capabilities through the securities lending markets and in the form of credit facilities with banks. As a general practice, we maintain sufficient levels of cash on hand to provide us with a buffer should we need immediately available funds for any reason. In addition, pursuant to our liquidity risk management plan we perform periodic liquidity stress tests, which are designed to identify and reserve liquid assets that would be available under market or idiosyncratic stress events. Based on our current level of operations, we believe our cash flows from operations, available cash and available borrowings will be adequate to meet our future liquidity needs for more than the next twelve months. As of December 31, 2023, liability balances in connection with securities loaned, payable to customers and our short-term borrowings were higher than the average monthly balance during the current year. Cash and cash equivalents held by our non-U.S. operating subsidiaries as of December 31, 2023 were $1,625 million ($1,394 million as of December 31, 2022). These funds are primarily intended to finance each individual operating subsidiary’s local operations, and thus would not be available to fund U.S. domestic operations unless repatriated through payment of dividends to IBG LLC. As of December 31, 2023, we had no intention to repatriate any amounts from non-U.S. operating subsidiaries. With the enactment of the U.S. Tax Cuts and Jobs Act on December 22, 2017, we recognized a liability for the one-time transition tax on deemed repatriation of earnings of some of our foreign subsidiaries for the year ended December 31, 2017. As a result, in the event dividends were to be paid to the Company in the future by a non-U.S. operating subsidiaries, the Company would not be required to accrue and pay income taxes on such dividends, except for foreign taxes in the form of dividend withholding tax, and in connection with accumulated other comprehensive income/loss from currency exchange rate changes not previously taxed in the U.S., if any, imposed on the recipient of the distribution or dividend distribution tax imposed on the payor of the distribution. Historically, our consolidated equity has consisted primarily of accumulated retained earnings, which to date have been sufficient to fund our operations and growth. Our consolidated equity increased 21% to $14.1 billion as of December 31, 2023, from $11.6 billion as of December 31, 2022. This increase is attributable to total comprehensive income, partially offset by distributions and dividends paid during 2023. 58 Cash Flows The table below presents our cash flows from operating activities, investing activities and financing activities for the periods indicated. 2023 Year-Ended December 31, 2022 (in millions) 2021 Net cash provided by operating activities. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Our cash flows from investing activities are primarily related to other investments, capitalized internal software development, purchases and sales of memberships, trading rights and shares at exchanges where we trade, and strategic investments where such investments may enable us to offer better execution alternatives to our current and prospective customers, allow us to influence exchanges to provide competing products at better prices using sophisticated technology, or enable us to acquire either technology or customers faster than we could develop them on our own. Our cash flows from financing activities are comprised of short-term borrowings, capital transactions and payments made to Holdings under the Tax Receivable Agreement. Short-term borrowings from banks are part of our daily cash management in support of operating activities. Capital transactions consist primarily of quarterly dividends paid to common stockholders and related distributions paid to Holdings. Year Ended December 31, 2023: Our cash, cash equivalents and restricted cash (i.e., cash and cash equivalents that are subject to withdrawal or usage restrictions) increased by $3,990 million to $32.6 billion for the year ended December 31, 2023. We raised $4,544 million in net cash from operating activities mainly driven by customer credit balances which increased by $7.8 billion, securities loaned which increased $2.4 billion, and other receivables (primarily receivables from brokers, dealers and clearing organizations) which decreased $1.8 billion; partially offset by customer margin loans which increased $5.7 billion, securities segregated for regulatory purposes which increased $3.6 billion, and securities borrowed which increased $1.1 billion. We used net cash of $676 million in our investing and financing activities, primarily for distributions to noncontrolling interests, short-term borrowings, dividends paid to our common stockholders and payments made to Holdings under the Tax Receivable Agreement. Investing activities mainly consisted of distributions and proceeds from sales of other investments, and purchases of other investments and property, equipment and intangible assets. Year Ended December 31, 2022: For a discussion of changes in cash flows for the year ended December 31, 2022 refer to our Annual Report on Form 10-K filed with the SEC on February 24, 2023. Year Ended December 31, 2021: For a discussion of changes in cash flows for the year ended December 31, 2021 refer to our Annual Report on Form 10-K filed with the SEC on February 25, 2022. Senior Notes In 2020, IBG LLC initiated a program to offer senior notes in private placements to certain qualified customers of IB LLC. IBG LLC intends to use the proceeds for general financing purposes when interest spread opportunities arise. The senior notes are offered at an issue price of $1 thousand per note at an interest rate calculated by adding the benchmark rate to a rate (spread) that IBG LLC announces from time to time. The benchmark rate is the effective federal funds rate as reported by the Federal Reserve Bank of New York on the morning of the date of the offering. The senior notes mature no later than the thirtieth day following the issuance 59 date, and IBG LLC, at its option, may redeem the senior notes at any time, at a redemption price equal to 100% of the principal amount of the senior notes to be redeemed, plus accrued and unpaid interest. During the year ended December 31, 2023, the Company did not issue any senior notes. Regulatory Capital Requirements As of December 31, 2023, all operating subsidiaries were in compliance with their respective regulatory capital requirements. For additional information regarding our regulatory capital requirements see Note 16 – ‘‘Regulatory Requirements’’ to the audited consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K. Capital Expenditures Our capital expenditures are comprised of compensation costs of our software engineering staff for development of software for internal use and expenditures for computer, networking and communications hardware, and leasehold improvements. These expenditure items are reported as property, equipment, and intangible assets. Capital expenditures for property, equipment, and intangible assets were approximately $49 million, $69 million and $77 million for the three years ended December 31, 2023, 2022, and 2021, respectively. In the future, we plan to meet capital expenditure needs with cash from operations and cash on hand, as we continue our focus on technology infrastructure initiatives to further enhance our competitive position. In response to changing economic conditions, we believe we have the flexibility to modify our capital expenditures by adjusting them (either upward or downward) to match our actual performance. If we pursue any additional strategic acquisitions, we may incur additional capital expenditures.

Through December 31, 2023, approximately $268 million of cumulative cash payments have been made. (2) The Tax Act implemented a modified territorial tax system that includes a one-time transition tax on deemed repatriated earnings of foreign subsidiaries to be paid over an eight-year period starting in 2018. We believe this tax will not have a material impact on our liquidity. Seasonality Our businesses are subject to seasonal fluctuations, reflecting varying numbers of market participants at times during the year, varying numbers of trading days from quarter-to-quarter, and declines in trading activity due to holidays. Typical seasonal trends may be superseded by market or world events, which can have a significant impact on prices and trading volume. 60 Inflation Although we cannot accurately anticipate the effects of inflation on our operations, we believe that, for the current year, inflation may have indirectly had a material impact on our results of operations. Inflation has been one of the factors driving our employee compensation and benefits expenses higher during the current period, although as a percentage of net revenues these expenses remain stable. In an effort to stem inflation, central banks have increased benchmark interest rates in most currencies, which has contributed to our net interest income. Inflation may also be a contributing factor to general uncertainty in the markets in the foreseeable future. Statements about future inflation are subject to the risk that actual inflation and its effects may differ, possibly materially, due to, among other things, changes in economic growth, impact of supply chain disruptions, unemployment and consumer demand. Investments in U.S. Government Securities We invest in U.S. government securities to satisfy U.S. regulatory requirements. As a broker-dealer, unlike banks, we are required to mark these investments to market even though we intend to hold them to maturity. Sudden increases (decreases) in interest rates will cause mark-to-market losses (gains) on these securities, which are recovered (eliminated) if we hold them to maturity, as currently intended. As of December 31, 2023, all of our U.S. government securities mature within three months. The impact of changes in interest rates is further described in Part II, Item 7A of this Annual Report on Form 10-K entitled ‘‘Quantitative and Qualitative Disclosures about Market Risk.’’ Strategic Investments and Acquisitions We regularly evaluate potential strategic investments and acquisitions. We hold strategic investments in certain electronic trading exchanges, including BOX Options Exchange, LLC. We also hold strategic investments in certain businesses, including Tiger Brokers, an online stock brokerage established for Chinese retail and institutional customers, and Zero Hash Holdings Ltd., a crypto-service provider, in which we have beneficial ownership interests of 6.2% and 31.6%, respectively. We intend to continue making acquisitions on an opportunistic basis, generally only when the acquisition candidate will, in our opinion, enable us to offer better execution alternatives to our current and prospective customers, allow us to influence exchanges to provide competing products at better prices using sophisticated technology, or enable us to acquire either technology or customers faster than we could develop them on our own. As of December 31, 2023, there were no definitive agreements with respect to any material acquisition. Certain Information Concerning Off-Balance-Sheet Arrangements We may be exposed to a risk of loss not reflected in our consolidated financial statements for futures products, which represent our obligations to settle at contracted prices, and which may require us to repurchase or sell in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk, as our cost to liquidate such futures contracts may exceed the amounts reported in our consolidated statements of financial condition. Critical Accounting Policies and Estimates Our consolidated financial statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. We believe that the critical policies listed below represent the most significant estimates used in the preparation of our consolidated financial statements. See Note 2 – ‘‘Significant Accounting Policies’’ to the audited consolidated financial statements for a summary of our significant accounting policies in Part II, Item 8 of this Annual Report on Form 10-K. 61 Contingencies Our policy is to estimate and accrue for potential losses that may arise out of litigation and regulatory proceedings, to the extent that such losses are probable and can be estimated. Significant judgment is required in making these estimates and our final liabilities may ultimately be materially different. Our total liability accrued with respect to litigation and regulatory proceedings is determined on a case by case basis and represents an estimate of probable losses based on, among other factors, the progress of each case, our experience with and industry experience with similar cases and the opinions and views of internal and external legal counsel. Given the inherent difficulty of predicting the outcome of litigation and regulatory matters, particularly in cases or proceedings in which substantial or indeterminate damages or fines are sought, or where cases or proceedings are in the early stages, we cannot estimate losses or ranges of losses for cases or proceedings where there is only a reasonable possibility that a loss may be incurred. Income Taxes Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws and reflect management’s best assessment of estimated future taxes to be paid. We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgment and estimates. Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statement recognition of the underlying assets and liabilities. In evaluating our ability to recover our deferred tax assets within the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. We record tax liabilities in accordance with Financial Accounting Standards Board (‘‘FASB’’) ASC Topic 740 and adjust these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available. We recognize that a tax benefit from an uncertain tax position may be recognized only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. Accounting Pronouncements Issued but Not Yet Adopted For additional information regarding FASB Accounting Standards Updates (‘‘ASU’’s) that have been issued but not yet adopted and that may impact the Company, refer to Note 2 – ‘‘Significant Accounting Policies’’ to the audited consolidated financial statements in Part II, Item 8 of this Annual Report on form 10-K. 62 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to various market risks. Our exposures to market risks arise from assumptions built into our pricing models, equity price risk, foreign currency exchange rate fluctuations related to our international operations, changes in interest rates and risks relating to the extension of margin credit to our customers. Market risk refers to the risk that a change in the level of one or more market prices, rates, indices, implied volatilities (the price volatility of the underlying instrument imputed from option prices), correlations or other market factors, such as market liquidity, will result in losses for a position or portfolio. Generally, we incur trading-related market risk as a result of our remaining market making activities, where the substantial majority of our Value-at-Risk (‘‘VaR’’) for market risk exposures is generated. In addition, we incur non-trading-related market risk primarily from investment activities and from foreign currency exposure held in the equity of our foreign subsidiaries, i.e., our non-U.S. brokerage subsidiaries and information technology subsidiaries, and held to meet target balances in our currency diversification strategy. We use various risk management tools in managing our market risk, which are embedded in our real-time market making systems. We employ certain hedging and risk management techniques to protect us from a severe market dislocation. Our risk management policies are developed and implemented by our Steering Committee, which is chaired by our Chief Executive Officer and comprised of senior executives of our various operating subsidiaries. The strategy of our remaining market making activities is to calculate quotes a few seconds ahead of the market and execute small trades at a tiny but favorable differential as a result. This strategy is made possible by our proprietary pricing model, which evaluates and monitors the risks inherent in our portfolio, assimilates external market data and reevaluates the outstanding quotes in our portfolio many times per second. Our model automatically rebalances our positions throughout each trading day to manage risk exposures on our options and futures positions and the underlying securities and will price the increased risk that a position would add to the overall portfolio into the bid and offer prices we post. Under risk management policies implemented and monitored primarily through our computer systems, reports to management, including risk profiles, profit and loss analysis and trading performance, are prepared on a real-time basis as well as daily and periodical bases. Although our remaining market making activities are completely automated, the trading process and our risk are monitored by a team of individuals who, in real time, observe various risk parameters of our consolidated positions. Our assets and liabilities are marked-to-market daily for financial reporting purposes and re-valued continuously throughout the trading day for risk management and asset/liability management purposes. We use a covariant VaR methodology to measure, monitor and review the market risk of our market making portfolios, with the exception of fixed income products, and our currency exposures. The risk of fixed income products, which comprise primarily U.S. government securities, is measured using a stress test. Pricing Model Exposure As described above, our proprietary pricing model, which continuously evaluates and monitors the risks inherent in our portfolio, assimilates external market data and reevaluates the outstanding quotes in our entire portfolio many times per second. Certain aspects of the model rely on historical prices of securities. If the behavior of price movements of individual securities diverges substantially from what their historical behavior would predict, we might incur trading losses. We attempt to limit such risks by diversifying our portfolio across many different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security. Historically, our losses from these events have been immaterial in comparison to our annual trading profits. Foreign Currency Exposure As a result of our international activities and accumulated earnings in our foreign subsidiaries, our income and equity are exposed to fluctuations in foreign exchange rates. For example, some of our European and Asian operations are conducted by our Swiss subsidiary, IBKRFS. IBKRFS is regulated by the Swiss Financial Market Supervisory Authority as a securities dealer and its financial statements are presented in Swiss francs. Accordingly, IBKRFS is exposed to certain foreign exchange risks as described below: • IBKRFS buys and sells securities denominated in various currencies and carries bank balances and borrows and lends such currencies in its regular course of business. At the end of each accounting period, IBKRFS’ assets and liabilities are revalued into Swiss francs for presentation in its financial 63 statements. The resulting foreign currency gains or losses are reported in IBKRFS’ income statement and, as translated into U.S. dollars for U.S. GAAP purposes, in our consolidated statements of comprehensive income as a component of other income. • IBKRFS’ financial statements are presented in Swiss francs (i.e., its functional currency) as noted above. At the end of each accounting period, IBKRFS’ equity is translated at the then prevailing exchange rate into U.S. dollars and the resulting translation gain or loss is reported as OCI in our consolidated statements of financial condition and consolidated statements of comprehensive income. OCI is also produced by our other non-U.S. subsidiaries. Historically, we have taken the approach of not hedging the above exposures, based on the notion that the cost of constantly hedging over the years would amount to more than the random impact of rate changes on our non-U.S. dollar balances. For instance, an increase in the value of the Swiss franc would be unfavorable to the earnings of IBKRFS but would be counterbalanced to some extent by the fact that the translation gain or loss into U.S. dollars is likely to move in the opposite direction. Our risk management systems incorporate cash forex to hedge our currency exposure at little or no cost. Currency spot positions entered into as part of our currency diversification strategy are held by the parent holding company, IBG LLC. In connection with the development of our currency diversification strategy, we determined to base our equity in GLOBALs, a basket of currencies. Because we conduct business in many countries and many currencies and because we consider ourselves a global enterprise based in a diversified basket of currencies rather than a U.S. dollar-based company, we actively manage our global currency exposure by maintaining our equity in GLOBALs. The U.S. dollar value of the GLOBAL increased 0.41% as of December 31, 2023 compared to December 31, 2022. As of December 31, 2023, approximately 25% of our equity was denominated in currencies other than the U.S. dollar. The table below presents a comparison of the U.S. dollar equivalent of the GLOBAL for the periods indicated. Currency Composition FX Rate GLOBAL in USD Equiv. % of Comp.

The full effect of the GLOBAL is captured in the consolidated statements of comprehensive income. Reported results on a comprehensive basis reflect the U.S. GAAP convention that requires the reporting of currency translation results contained in OCI as part of reportable earnings. Interest Rate Risk We had no variable-rate debt outstanding as of December 31, 2023. We pay our customers interest based on benchmark overnight interest rates in various currencies, when interest rates are above a benchmark rate plus a small spread, on cash balances above $10 thousand (or equivalent) in securities accounts holding more than $100 thousand and at lower, tiered rates for accounts holding less than $100 thousand (or equivalent) net asset value. In currencies with negative rates, we pass through the cost of holding certain cash balances to our customers; therefore, we charge our customers interest on these cash balances. In a normal rate environment, we typically invest a portion of these funds in U.S. government securities with maturities of up to two years, although 64 given the current interest rate environment, at this time all such investments mature within three months. If interest rates were to increase rapidly and substantially, our net interest income would not increase proportionally with the interest rates for the portion of the funds invested at fixed yields. In addition, the mark-to-market changes in the value of these fixed rate securities will be reflected in other income, instead of net interest income. Our margin balances are priced to a benchmark rate plus a spread, with a minimum charge of 0.75% in U.S. dollars and most foreign currencies. At negative or near-zero benchmark rates, such as during 2021, our interest sensitivity to rate increases is limited to the extent that a higher benchmark rate plus a spread may still be below the minimum charge. Based on customer balances and investments outstanding as of December 31, 2023, and assuming reinvestment of maturing instruments in instruments of short-term duration, an unexpected increase of 0.25% over current U.S. dollar interest rate levels would increase our net interest income by approximately $56 million on an annualized basis, assuming the full effect of reinvestment at higher rates. A 0.25% increase in all the relevant non-U.S. dollar benchmark rates would increase our net interest income by approximately $18 million to $20 million on an annualized basis. Our interest rate sensitivity estimate contains separate assumptions for U.S. dollar rates from other currencies’ rates and it isolates the effects of a rate increase on reinvestments. We do not approximate mark-to-market impact from interest rate changes; if U.S. government securities whose prices were to fall under these scenarios were held to maturity, as intended, then the reduction in other income would be temporary, as the securities would mature at par value. If such securities were sold prior to maturity, the loss would be realized and the proceeds reinvested at prevailing higher interest rates. We also face the potential for reduced net interest income from customer deposits and margin loans if benchmark rates were to fall. Based on customer balances and investments outstanding as of December 31, 2023, and assuming reinvestment of maturing instruments in instruments of short-term duration, an unexpected decrease in U.S. dollar interest rates of 0.25% would decrease our net interest income by approximately $56 million on an annualized basis, assuming the full effect of reinvestment at lower rates. A 0.25% decrease in all the relevant non-U.S. dollar benchmark rates would decrease our net interest income by approximately $18 million to $20 million on an annualized basis. We also face interest rate risk due to positions carried for our remaining market making activities to the extent that long or short stock positions may have been established for future or forward dates on options or futures contracts and the value of such positions is impacted by interest rates. The amount of such risk cannot be quantified, however, the current low level of market making positions does not indicate a material potential exposure. Dividend Risk We face dividend risk in our remaining market making activities as we derive revenues and incur expenses in the form of dividend income and expense, respectively, from our inventory of equity securities, and must make payments in lieu of dividends on short positions in equity securities within our portfolio. Projected future dividends are an important component of pricing equity options and other derivatives, and incorrect projections may lead to trading losses. The amount of such risk cannot be quantified, however, the current low level of market making positions does not indicate a material potential exposure. Margin Loans We extend margin loans to our customers, which are subject to various regulatory requirements. Margin loans are collateralized by cash and securities in the customers’ accounts. The risks associated with margin credit increase during periods of fast market movements or in cases where collateral is concentrated and market movements occur. During such times, customers who utilize margin loans and who have collateralized their obligations with securities may find that the securities have a rapidly depreciating value and may not be sufficient to cover their obligations in the event of a liquidation. We are also exposed to credit risk when our customers execute transactions, such as short sales of options and equities that can expose them to risk beyond their invested capital. We expect this kind of exposure to increase with the growth of our overall business. Because we indemnify and hold harmless our clearing houses and counterparties from certain liabilities or claims, the use of margin loans and short sales may expose us to significant off-balance-sheet risk if collateral requirements are not sufficient to fully cover losses that customers may incur and those customers fail to satisfy their obligations. As of December 31, 2023, we extended $44.5 billion in margin loans to our customers. The amount of risk to which we are exposed from the margin loans we extend to our customers and from short sale transactions by our customers is unlimited and not quantifiable as the risk is dependent upon analysis of a potentially significant and undeterminable rise or fall in stock prices. Our account level margin requirements meet or exceed those required 65 by Regulation T of the Board of Governors of the Federal Reserve and FINRA portfolio margin rules, as applicable. As a matter of practice, we enforce real-time margin compliance monitoring and liquidate customers’ positions if their equity falls below required margin requirements. We have a comprehensive policy implemented in accordance with regulatory standards to assess and monitor the suitability of investors to engage in various trading activities. To mitigate our risk, we also continuously monitor customer accounts to detect excessive concentration, large orders or positions, patterns of day trading and other activities that indicate increased risk to us. Our credit exposure is to a great extent mitigated by our real-time margining system, which automatically evaluates each account throughout the trading day and closes out positions automatically for accounts that are found to be under-margined. While this methodology is effective in most situations, it may not be effective in situations where no liquid market exists for the relevant securities or commodities or where, for any reason, automatic liquidation for certain accounts has been disabled. Our Risk Management Committee continually monitors and evaluates our risk management policies, including the implementation of policies and procedures to enhance the detection and prevention of potential events to mitigate margin loan losses. Value-at-Risk We estimate VaR using a historical approach, which uses the historical daily price returns of underlying assets as well as estimates of the end of day implied volatility for options. Our one-day VaR is defined as the unrealized loss in portfolio value that, based on historically observed market risk factors, would have been exceeded with a frequency of one percent, based on a calculation with a confidence interval of 99%. Our VaR model generally takes into account exposures to equity and commodity price risk and foreign exchange rates. We use VaR as one of a range of risk management tools. Among their benefits, VaR models permit the estimation of a portfolio’s aggregate market risk exposure, incorporating a range of varied market risks and portfolio assets. One key element of the VaR model is that it reflects risk reduction due to portfolio diversification or hedging activities. However, VaR has various strengths and limitations, which include, but are not limited to: use of historical changes in market risk factors, which may not be accurate predictors of future market conditions, and may not fully incorporate the risk of extreme market events that are outsized relative to observed historical market behavior or reflect the historical distribution of results beyond the confidence interval; and reporting of losses in a single day, which does not reflect the risk of positions that cannot be liquidated or hedged in one day. A small proportion of market risk generated by trading positions is not included in VaR. The modeling of the risk characteristics of some positions relies on approximations that, under certain circumstances, could produce significantly different results from those produced using more precise measures. VaR is most appropriate as a risk measure for trading positions in liquid financial markets and will understate the risk associated with severe events, such as periods of extreme illiquidity. The VaR calculation simulates the performance of the portfolio based on several years of daily price changes of the underlying assets and determines the VaR as the calculated loss that occurs at the 99th percentile. Since the reported VaR statistics are estimates based on historical data, VaR should not be viewed as predictive of our future revenues or financial performance or of our ability to monitor and manage risk. There can be no assurance that our actual losses on a particular day will not exceed the indicated VaR or that such losses will not occur more than one time in 100 trading days. VaR does not predict the magnitude of losses which, should they occur, may be significantly greater than the VaR amount. Stress Test We estimate the market risk of our fixed income portfolio using a risk analysis model provided by a leading external vendor. For corporate bonds, this stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in five scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/−100 and +/−200 basis points. For U.S. government securities, the stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in three scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/−50 basis points. 66 VaR and Stress Test Measures Market Risk Category Trading(1) At December 31, 2023 At December 31, 2022 (in millions) Average 2023 High 2023 Equities and Currencies(2) . . . . . . . . . . . . . . . . . . . . . . . . .

The ‘‘Non-trading’’ category reflects investment activities and foreign currency exposures of the Company’s non-market making subsidiaries (i.e., its brokerage subsidiaries and information technology subsidiaries). This category also includes corporate activities in foreign exchange designed to achieve the Company’s currency diversification strategy. The average and high VaR amounts are based on the four quarter ending calculations performed in 2023. (2) Equities and currencies held for market making purposes are combined because these products are part of an integrated, hedged market making portfolio, on which the risk is measured using VaR. (3) The Non-Trading – Fixed Income, Other category contains primarily U.S. government securities held in segregated safekeeping accounts for the exclusive benefit of our brokerage customers, on which the risk is measured using a stress test analysis. 67 ITEM 8.

Greenwich, CT Opinion on the Financial Statements We have audited the accompanying consolidated statements of financial condition of Interactive Brokers Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2023 and 2022, the related consolidated statements of comprehensive income, cash flows and changes in equity, for each of the three years in the period ended December 31, 2023, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the ‘‘financial statements’’). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 26, 2024, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Income taxes — Refer to Notes 2 and 11 to the financial statements Critical Audit Matter Description The Company’s income tax expense, deferred tax assets and liabilities are based on enacted tax laws and reflects management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in both the U.S. and numerous foreign jurisdictions. The Company has deferred tax assets and liabilities that arose from temporary differences between tax and financial statement recognition of underlying assets and liabilities. Determining income tax expense and deferred tax assets and liabilities requires significant management judgments and estimates. 69 We identified management’s calculation of income tax expense and deferred tax assets and liabilities as a critical audit matter because of the significant judgments and estimates management makes to determine these amounts. Performing audit procedures to evaluate the reasonableness of management’s interpretation of tax law in a multitude of jurisdictions across the Company’s global operations, and its estimate of the associated tax expense and deferred tax assets and liabilities, required a high degree of auditor judgment and increased effort, including the need to involve our income tax specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to income tax expense and deferred tax assets and liabilities included, among others, the following which were performed with the assistance of our income tax specialists: - - - - Testing the operating effectiveness of controls over income tax balances and deferred tax assets and liabilities. Evaluating the Company’s income tax expense calculation, including testing the appropriateness of income tax rates applied and of income allocations among the taxing jurisdictions, and the mathematical accuracy of the calculation. Evaluating the Company’s analyses supporting its conclusions as to the recognition and measurement of deferred tax assets and liabilities. Evaluating management’s assessment of the Company’s ability to utilize the net deferred tax assets in future years. /s/ Deloitte & Touche LLP New York, New York February 26, 2024 We have served as the Company’s auditor since 1990. 70 Interactive Brokers Group, Inc. and Subsidiaries Consolidated Statements of Financial Condition (in millions, except share amounts) Assets Cash and cash equivalents . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Significant Accounting Policies Basis of Presentation These consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. (‘‘U.S. GAAP’’) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (‘‘SEC’’) regarding financial reporting with respect to Form 10-K. These consolidated financial statements include the accounts of the Company and its consolidated subsidiaries and reflect all adjustments of a normal and recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the periods presented. Principles of Consolidation, including Noncontrolling Interests These consolidated financial statements include the accounts of IBG, Inc. and its majority and wholly-owned subsidiaries. As sole managing member of IBG LLC, IBG, Inc. exerts control over IBG LLC’s operations. In accordance with Financial Accounting Standards Board (‘‘FASB’’) Accounting Standards Codification (‘‘ASC’’) Topic 810, ‘‘Consolidation,’’ the Company consolidates IBG LLC’s financial statements and records the interests in IBG LLC that it does not own as noncontrolling interests. The Company’s policy is to consolidate all other entities in which it owns more than 50% unless it does not have control and any potential variable interest entities (‘‘VIEs’’) where the Company is deemed to be the primary beneficiary when it has the power to make the decisions that most significantly affect the economic performance of the VIE and has the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. As of December 31, 2023, the Company was not the primary beneficiary of any VIEs. All inter-company balances and transactions have been eliminated. 75 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in these consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. Such estimates include the allowance for credit losses, valuation of certain investments, compensation accruals, current and deferred income taxes, and contingency reserves. Fair Value Substantially all of the Company’s assets and liabilities, including financial instruments, are carried at fair value based on observable market prices and are marked to market, or are assets and liabilities which are short-term in nature and are carried at amounts that approximate fair value. The Company applies the fair value hierarchy in accordance with FASB ASC Topic 820, ‘‘Fair Value Measurement’’ (‘‘ASC Topic 820’’), to prioritize the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are: Level 1 Level 2 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Quoted prices for similar assets in an active market, quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly. Level 3 Prices or valuations that require inputs that are both significant to fair value measurement and unobservable. Financial instruments owned, at fair value, and financial instruments sold, but not yet purchased, at fair value are generally classified as Level 1 of the fair value hierarchy. The Company’s Level 1 financial instruments, which are valued using quoted market prices as published by exchanges and clearing houses or otherwise broadly distributed in active markets, include active listed stocks, options, warrants and U.S. and foreign government securities. The Company does not adjust quoted prices for financial instruments classified as Level 1 of the fair value hierarchy, even if the Company may hold a large position whereby a purchase or sale could reasonably be expected to impact quoted prices. Currency forward contracts are valued using broadly distributed bank and broker prices and are classified as Level 2 of the fair value hierarchy since inputs to their valuation can generally be corroborated by market data. Precious metals are valued using an internal model, which incorporates the exchange-traded futures price of the underlying instruments, benchmark interest rates and estimated storage costs, and are classified as Level 2 of the fair value hierarchy since the significant inputs to their valuation are observable. Other securities that are not traded in active markets are also classified as Level 2 of the fair value hierarchy. Level 3 financial instruments are comprised of securities that have been delisted or otherwise are no longer tradable in active markets and have been valued by the Company based on internal estimates. Earnings per Share Earnings per share (‘‘EPS’’) is computed in accordance with FASB ASC Topic 260, ‘‘Earnings per Share.’’ Basic EPS is computed by dividing the net income available for common stockholders by the weighted average number of shares outstanding for that period. Diluted EPS is calculated by dividing the net income available for common stockholders by the diluted weighted average shares outstanding for that period. Diluted EPS includes the 76 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) determinants of basic EPS and, in addition, reflects the dilutive effect of shares of common stock estimated to be distributed in the future under the Company’s stock-based compensation plans, with no adjustments to net income available for common stockholders for potentially dilutive common shares. Current Expected Credit Losses The Company follows FASB ASC Topic 326 – ‘‘Financial Instruments – Credit Losses’’ (‘‘ASC Topic 326’’) which applies to financial assets measured at amortized cost, held-to-maturity debt securities and off-balance sheet credit exposures. For on-balance sheet assets, an allowance must be recognized at the origination or purchase of in-scope assets and represents the expected credit losses over the contractual life of those assets. Expected credit losses on off-balance sheet credit exposures must be estimated over the contractual period the Company is exposed to credit risk as a result of a present obligation to extend credit. The impact to the current period is not material since the Company’s in-scope assets are primarily subject to collateral maintenance provisions for which the Company elected to apply the practical expedient of reporting the difference between the fair value of the collateral and the amortized cost for the in-scope assets as the allowance for current expected credit losses. Cash and Cash Equivalents Cash and cash equivalents consist of deposits with banks and all highly liquid investments, with maturities of three months or less, that are not segregated and deposited for regulatory purposes or to meet margin requirements at clearing houses and clearing banks. Cash and Securities - Segregated for Regulatory Purposes As a result of customer activities, certain operating subsidiaries are obligated by rules mandated by their primary regulators to segregate or set aside cash or qualified securities to satisfy such regulations, which have been promulgated to protect customer assets. Restricted cash represents cash and cash equivalents that are subject to withdrawal or usage restrictions. Cash segregated for regulatory purposes meets the definition of restricted cash and is included in ‘‘cash, cash equivalents and restricted cash’’ in the consolidated statements of cash flows. The table below presents the composition of the Company’s securities segregated for regulatory purposes for the periods indicated.

Securities Borrowed and Securities Loaned Securities borrowed and securities loaned are recorded at the amount of the cash collateral advanced or received. Securities borrowed transactions require the Company to provide counterparties with collateral, which may be in the form of cash, letters of credit or other securities. With respect to securities loaned, the Company receives collateral, which may be in the form of cash or other securities in an amount generally in excess of the fair value of the securities loaned. The Company monitors the market value of securities borrowed and loaned daily, with 77 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) additional collateral obtained or refunded as permitted contractually. The Company’s policy is to net, in the consolidated statements of financial condition, securities borrowed and securities loaned contracts entered into with the same counterparty that meet the offsetting requirements prescribed in FASB ASC Topic 210-20, ‘‘Balance Sheet – Offsetting’’ (‘‘ASC Topic 210-20’’). Securities lending fees received and paid by the Company are included in interest income and interest expense, respectively, in the consolidated statements of comprehensive income. Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase Securities purchased under agreements to resell and securities sold under agreements to repurchase, which are reported as collateralized financing transactions, are recorded at contract value, which approximates fair value. To ensure that the fair value of the underlying collateral remains sufficient, the collateral is valued daily with additional collateral obtained or excess collateral returned, as permitted under contractual provisions. The Company’s policy is to net, in the consolidated statements of financial condition, securities purchased under agreements to resell transactions and securities sold under agreements to repurchase transactions entered into with the same counterparty that meet the offsetting requirements prescribed in ASC Topic 210-20. Financial Instruments Owned and Financial Instruments Sold, But Not Yet Purchased, at Fair Value Financial instrument transactions are accounted for on a trade date basis. Financial instruments owned and financial instruments sold, but not yet purchased are stated at fair value based upon quoted market prices, or if not available, are valued by the Company based on internal estimates (see Fair Value above). The Company’s financial instruments pledged to counterparties where the counterparty has the right, by contract or custom, to sell or repledge the financial instruments are reported as financial instruments owned and pledged as collateral in the consolidated statements of financial condition. Customer Receivables and Payables Receivables from and payables to customers include amounts due on cash and margin transactions, including futures contracts transacted on behalf of customers. Securities owned by customers, including those that collateralize margin loans or other similar transactions, are not reported in the consolidated statements of financial condition. Amounts receivable from customers that are determined by management to be uncollectible are recorded as customer bad debt expense in the consolidated statements of comprehensive income. Receivables from and Payables to Brokers, Dealers and Clearing Organizations Receivables from and payables to brokers, dealers and clearing organizations include net receivables and payables from unsettled trades, including amounts related to futures and options on futures contracts executed on behalf of customers, amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (‘‘fails to deliver’’) and cash deposits. Payables to brokers, dealers and clearing organizations also include amounts payable for securities not received by the Company from a seller by the settlement date (‘‘fails to receive’’). Investments The Company makes certain strategic investments related to its business which are included in other assets in the consolidated statements of financial condition. The Company accounts for these investments as follows: • Under the equity method of accounting as required under FASB ASC Topic 323, ‘‘Investments - Equity Method and Joint Ventures.’’ These investments, including where the investee is a limited partnership or limited liability company, are recorded at the fair value amount of the Company’s initial investment and are adjusted each period for the Company’s share of the investee’s income or loss. Contributions paid to and distributions received from equity method investees are recorded as additions or reductions, respectively, to the respective investment balance. 78 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) • At fair value, if the investment in equity securities has a readily determinable fair value. • At adjusted cost, if the investment does not have a readily determinable fair value. Adjusted cost represents the historical cost, less impairment if any. If the Company identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, the Company measures the equity security at fair value as of the date that the observable transaction occurred in accordance with FASB ASC Topic 321, ‘‘Investments in Equity Securities.’’ A judgmental aspect of accounting for investments is evaluating whether a decline in the value of an investment has occurred. The evaluation of impairment is dependent on specific quantitative and qualitative factors and circumstances surrounding an investment, including recurring operating losses, credit defaults and subsequent rounds of financing. Most of the Company’s equity investments do not have readily determinable market values. All investments are reviewed for changes in circumstances or occurrence of events that suggest the Company’s investment may not be recoverable. An impairment loss, if any, is recognized in the period the determination is made. The table below presents the composition of the Company’s investments for the periods indicated.

(2) These investments do not qualify for the equity method of accounting. Dividends received are included in other income in the consolidated statements of comprehensive income. Property, Equipment and Intangible Assets Property, equipment and intangible assets, which are included in other assets in the consolidated statements of financial condition, consist of leasehold improvements, computer equipment, software developed for the Company’s internal use, office furniture and equipment. Property and equipment are recorded at historical cost, less accumulated depreciation and amortization. Additions and improvements that extend the lives of assets are capitalized, while expenditures for repairs and maintenance are expensed as incurred. Depreciation and amortization are computed using the straight-line method. Equipment is depreciated over the estimated useful lives of the assets, while leasehold improvements are amortized over the lesser of the estimated economic useful life of the asset or the term of the lease. Computer equipment is depreciated over three to five years and office furniture and equipment are depreciated over five to seven years. Intangible assets with a finite life are amortized on a straight-line basis over their estimated useful lives of three to five years, and tested for recoverability whenever events indicate that the carrying amounts may not be recoverable. Qualifying costs for internally developed software are capitalized and amortized over the expected useful life of the developed software, not to exceed three years. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the consolidated statements of financial condition and any resulting gain or loss is recorded in other income in the consolidated statements of comprehensive income. Fully depreciated (or amortized) assets are retired periodically throughout the year. 79 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) Leases The Company reviews all relevant contracts to determine if the contract contains a lease at its inception date. A contract contains a lease if the contract conveys to the company the right to control the use of an underlying asset for a period of time in exchange for consideration. If the Company determines that a contract contains a lease, it recognizes, in the consolidated statements of financial condition, a lease liability and a corresponding right-of-use asset on the commencement date of the lease. The lease liability is initially measured at the present value of the future lease payments over the lease term using the rate implicit in the lease or, if not readily determinable, the Company’s secured incremental borrowing rate. An operating lease right-of-use asset is initially measured at the value of the lease liability minus any lease incentives and initial direct costs incurred plus any prepaid rent. The Company’s leases are classified as operating leases and consist of real estate leases for office space, data centers and other facilities. Each lease liability is measured using the Company’s secured incremental borrowing rate, which is based on an internally developed yield curve using interest rates of third parties’ corporate debt issued with a similar risk profile as the Company and a duration similar to the lease term. The Company’s leases have remaining terms of less than one year to thirteen years, some of which include options to extend the lease term, and some of which include options to terminate the lease upon notice. The Company considers these options when determining the lease term used to calculate the right-of-use asset and the lease liability when the Company is reasonably certain it will exercise such option. The Company’s operating leases contain both lease components and non-lease components. Non-lease components are distinct elements of a contract that are not related to securing the use of the underlying assets, such as common area maintenance and other management costs. The Company elected to measure the lease liability by combining the lease and non-lease components as a single lease component. As such, the Company includes the fixed payments and any payments that depend on a rate or index that relate to the lease and non-lease components in the measurement of the lease liability. Some of the non-lease components are variable and not based on an index or rate, and as a result, are not included in the measurement of the right-of-use asset or lease liability. Operating lease expense is recognized on a straight-line basis over the lease term and is included in occupancy, depreciation and amortization expense in the Company’s consolidated statements of comprehensive income. Crypto-assets safeguarding liability and corresponding safeguarding asset Staff Accounting Bulletin No. 121 (‘‘SAB 121’’) requires an entity to recognize a liability to reflect its obligation to safeguard the crypto-assets held for its platform users and a corresponding safeguarding asset on its balance sheet, even when the Company does not control the crypto-assets. Both the crypto-asset safeguarding liability and the corresponding safeguarding asset shall be measured at the fair value of the crypto-assets held for the platform users with the measurement of the safeguarding asset taking into account any potential loss events. The Company has entered into agreements with third-party Cryptocurrency Service Providers (‘‘CSPs’’), which provide (i) cryptocurrency exchange platforms and services whereby investors can buy and sell certain cryptocurrencies and (ii) custody services for certain cryptocurrencies, enabling some of our customers to trade and custody Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH) and potentially other cryptocurrencies via CSPs. Even though the Company is not responsible for the safeguarding of crypto-assets at the CSPs, its customers’ crypto-assets held at the CSPs are deemed to be in scope of SAB 121. 80 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) As of December 31, 2023, the fair value of the Company’s customers’ crypto-assets held at the CSPs that the Company recognized on its balance sheet for both the crypto-asset safeguarding liability and the corresponding safeguarding asset, which are included in ‘‘accounts payable, accrued expenses and other liabilities’’ and ‘‘other assets,’’ respectively, in the consolidated statements of financial condition, was $172 million ($80 million as of December 31, 2022), which consisted of $120 million of Bitcoin, $50 million of Ethereum and $2 million of other crypto-assets. Changes in the fair value of crypto-assets, held by our customers, do not impact our consolidated statements of comprehensive income unless a loss event is identified. As of December 31, 2023, no loss events were identified. Comprehensive Income and Foreign Currency Translation The Company’s operating results are reported in the consolidated statements of comprehensive income pursuant to FASB ASC Topic 220, ‘‘Comprehensive Income.’’ Comprehensive income consists of two components: net income and other comprehensive income (‘‘OCI’’). The Company’s OCI is comprised of gains and losses resulting from translating foreign currency financial statements of non-U.S. subsidiaries, net of related income taxes, where applicable. In general, the practice and intention of the Company is to reinvest the earnings of its non-U.S. subsidiaries in those operations; therefore, tax is usually not accrued on OCI. The Company’s non-U.S. domiciled subsidiaries have a functional currency that is other than the U.S. dollar. Such subsidiaries’ assets and liabilities are translated into U.S. dollars at period-end exchange rates, and revenues and expenses are translated at average exchange rates prevailing during the period. Adjustments that result from translating amounts from a subsidiary’s functional currency to the U.S. dollar (as described above) are reported net of tax, where applicable, in accumulated OCI in the consolidated statements of financial condition. Revenue Recognition Commissions Commissions earned for executing and/or clearing transactions are accrued on a trade date basis and are reported as commissions in the consolidated statements of comprehensive income. Commissions also include payments for order flow income received from IBKR LiteSM liquidity providers. The Company’s IBKR LiteSM offering provides commission-free trades on U.S. exchange-listed stocks and ETFs and generates no commission revenues from customers on these trades. See Note 8 for further information on revenue from contracts with customers. Other Fees and Services The Company earns fee income on services provided to customers, which includes market data fees, risk exposure fees, payments for order flow from exchange-mandated programs, Insured Bank Deposit Sweep Program fees (‘‘FDIC sweep fees’’), minimum activity fees, and other fees and services charged to customers. Fee income is recognized either daily or monthly. See Note 8 for further information on revenue from contracts with customers. Interest Income and Expense The Company earns interest income and incurs interest expense primarily in connection with its electronic brokerage customer business and its securities lending activities, which are recorded on an accrual basis and are included in interest income and interest expense, respectively, in the consolidated statements of comprehensive income. 81 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) Principal Transactions Principal transactions include gains and losses as a result of changes in the fair value of financial instruments owned, at fair value, financial instruments sold, but not yet purchased, at fair value, and other investments measured at fair value (i.e., unrealized gains and losses) and realized gains and losses related to the Company’s principal transactions. Included are net gains and losses on stocks, options, U.S. and foreign government securities, municipal securities, futures, foreign exchange, precious metals and other derivative instruments, which are reported on a net basis in other income in the consolidated statements of comprehensive income. Dividends are integral to the valuation of stocks. Accordingly, dividend income and expense attributable to financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value, are reported on a net basis in other income in the consolidated statements of comprehensive income. Foreign Currency Gains and Losses Foreign currency balances are assets and liabilities in currencies other than the Company’s functional currency. At every reporting date, the Company revalues its foreign currency balances to its functional currency at the spot exchange rate and records the associated foreign currency gains and losses. These foreign currency gains and losses are reported in the consolidated statements of comprehensive income, as follows: (a) foreign currency gains and losses related to the Company’s currency diversification strategy are reported in other income; (b) foreign currency gains and losses arising from currency swap transactions are reported in interest income or interest expense; and (c) all other foreign currency gains and losses are reported in other income. Rebates Rebates consist of volume discounts, credits, or payments received from exchanges or other market centers related to the placement and/or removal of liquidity from the marketplace and are recorded on an accrual basis. Rebates are recorded net within execution, clearing and distribution fees in the consolidated statements of comprehensive income. Rebates received for trades executed on behalf of customers that elect tiered pricing are passed, in whole or part, to these customers, and such pass-through amounts are recorded net within commissions in the consolidated statements of comprehensive income. Stock-Based Compensation The Company follows FASB ASC Topic 718, ‘‘Compensation - Stock Compensation’’ (‘‘ASC Topic 718’’), to account for its stock-based compensation plans. ASC Topic 718 requires all share-based payments to employees to be recognized in the consolidated financial statements using a fair value-based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of the grant, thereby establishing the fair value of each grant. The fair value of awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of the plans’ post-employment provisions (as described below) and the remaining 50% over the related vesting period utilizing the ‘‘graded vesting’’ method permitted under ASC Topic 718. In the case of ‘‘retirement eligible’’ employees (those employees older than 59), 100% of awards are expensed when granted. Awards granted under stock-based compensation plans are subject to the plans’ post-employment provisions in the event an employee ceases employment with the Company. The plans provide that employees who discontinue employment with the Company without cause and continue to meet the terms of the plans’ post-employment provisions will be eligible to earn 50% of previously granted but not yet earned awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned awards. 82 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements 2. Significant Accounting Policies (Continued) Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740, ‘‘Income Taxes’’ (‘‘ASC Topic 740’’). The Company’s income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws (see Note 11) and reflect management’s best assessment of estimated future taxes to be paid. The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgment and estimates. Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statement recognition of underlying assets and liabilities. In evaluating the ability to recover deferred tax assets within the jurisdictions from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates the Company is using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested. The calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company’s global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. On December 15, 2022, the European Union (‘‘EU’’) formally adopted the EU’s Pillar Two Directive, effective January 1, 2024, which provides for a minimum effective tax rate of 15%, as established by the Organization for Economic Cooperation and Development (‘‘OECD’’) Pillar Two Framework. A significant number of other countries have either already or are expected to also implement similar legislation with varying effective dates. The Company is continuing to evaluate the potential impact of the EU’s Pillar Two Directive and similar legislations adopted by other countries on its future results of operations, financial condition and cash flows. The Company records tax liabilities in accordance with ASC Topic 740 and adjusts these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available. The Company recognizes a tax benefit from an uncertain tax position only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. The Company recognizes interest related to income tax matters as interest income or interest expense and penalties related to income tax matters as income tax expense in the consolidated statements of comprehensive income. 83 Interactive Brokers Group, Inc. and Subsidiaries Notes to Consolidated Financial Statements Effect on financial statements • Effective date: January 1, 2023. • The changes did not have a material impact on the Company’s consolidated financial statements.

Trading Activities and Related Risks Trading activities expose the Company to market and credit risks. These risks are managed in accordance with established risk management policies and procedures. To accomplish this, management has established a risk management process that includes: • • • a regular review of the risk management process by executive management as part of its oversight role; defined risk management policies and procedures supported by a rigorous analytic framework; and articulated risk tolerance levels as defined by executive management that are regularly reviewed to ensure that the Company’s risk-taking is consistent with its business strategy, its capital structure, and current and anticipated market conditions. Market Risk The Company is exposed to various market risks. Exposures to market risks arise from equity price risk, foreign currency exchange rate fluctuations and changes in interest rates. The Company seeks to mitigate market risk associated with trading inventories by employing hedging strategies that correlate rate, price and spread movements of trading inventories and related financing and hedging activities. The Company uses a combination of cash instruments and exchange-traded derivatives to hedge its market exposures. The Company does not apply hedge accounting. The following discussion describes the types of market risk faced: Equity Price Risk Equity price risk arises from the possibility that equity security prices will fluctuate, affecting the value of equity securities and other instruments that derive their value from a particular stock, a defined basket of stocks, or a stock index. The Company is subject to equity price risk primarily in financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value. The Company attempts to limit such risks by continuously reevaluating prices and by diversifying its portfolio across many 85 3. Trading Activities and Related Risks (Continued) different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security. Interest Rate Risk Interest rate risk arises from the possibility that changes in interest rates will affect the value of financial instruments. The Company is exposed to interest rate risk on cash and margin balances, positions carried in equity and fixed income securities, options, futures and on its borrowings. These risks are managed through investment policies and by entering into interest rate futures contracts. Currency Risk Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact the value of financial instruments. The Company manages this risk using spot (i.e., cash) currency transactions, currency futures contracts and currency forward contracts. The Company actively manages its currency exposure using a currency diversification strategy that is based on a defined basket of ten currencies internally referred to as the ‘‘GLOBAL.’’ These strategies minimize the fluctuation of the Company’s equity as expressed in GLOBALs, thereby diversifying its risk in alignment with these global currencies, weighted by the Company’s view of their importance. As the Company’s financial results are reported in U.S. dollars, the change in the value of the GLOBAL as expressed in U.S. dollars affects the Company’s earnings. The impact of this currency diversification strategy in the Company’s earnings is included in other income in the consolidated statements of comprehensive income. Credit Risk The Company is exposed to the risk of loss if a customer, counterparty or issuer fails to perform its obligations under contractual terms (‘‘default risk’’). Both cash instruments and derivatives expose the Company to default risk. The Company has established policies and procedures for mitigating credit risk on principal transactions, including reviewing and establishing limits for credit exposure, maintaining collateral and continually assessing the creditworthiness of counterparties. The Company’s credit risk is limited as contracts entered into are settled directly at securities and commodities clearing houses or are settled through member firms and banks with substantial financial and operational resources. Over-the-counter transactions, such as securities lending and contracts for differences (‘‘CFDs’’), are marked to market daily and are conducted with counterparties that have undergone a thorough credit review. The Company seeks to control the risks associated with its customer margin activities by requiring customers to maintain collateral in compliance with regulatory and internal guidelines. In the normal course of business, the Company executes, settles and finances various customer securities transactions. Execution of these transactions includes the purchase and sale of securities which exposes the Company to default risk arising from the potential that customers or counterparties may fail to satisfy their obligations. In these situations, the Company may be required to purchase or sell financial instruments at unfavorable market prices to satisfy obligations to customers or counterparties. Liabilities to other brokers and dealers related to unsettled transactions (i.e., securities fails to receive) are recorded at the amount for which the securities were purchased, and are paid upon receipt of the securities from other brokers or dealers. In the case of aged securities fails to receive, the Company may purchase the underlying security in the market and seek reimbursement for any losses from the counterparty. For cash management purposes, the Company enters into short-term securities purchased under agreements to resell and securities sold under agreements to repurchase transactions (‘‘repos’’) in addition to securities borrowing and lending arrangements, all of which may result in credit exposure in the event the counterparty to a transaction is unable to fulfill its contractual obligations. Repos are collateralized by securities with a market value in excess of the obligation under the contract. Similarly, securities lending agreements are collateralized by deposits of cash or securities. The Company attempts to minimize credit risk associated with these activities by monitoring collateral values daily and requiring additional collateral to be deposited with or returned to the Company as permitted under contractual provisions. 86 3. Trading Activities and Related Risks (Continued) Concentrations of Credit Risk The Company’s exposure to credit risk associated with its trading and other activities is measured on an individual counterparty basis, as well as by groups of counterparties that share similar attributes. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, credit limits are established and exposure is monitored in light of changing counterparty and market conditions. As of December 31, 2023, the Company did not have any material concentrations of credit risk outside the ordinary course of business. Off-Balance Sheet Risks The Company may be exposed to a risk of loss not reflected in the consolidated financial statements to settle futures and certain over-the-counter contracts at contracted prices, which may require repurchase or sale of the underlying products in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk as the Company’s cost to liquidate such contracts may exceed the amounts reported in the Company’s consolidated statements of financial condition. 4.

The noncontrolling interests in IBG LLC attributable to Holdings are reported as a component of total equity in the consolidated statements of financial condition. Recapitalization and Post-IPO Capital Structure Immediately before and immediately following the consummation of the IPO, IBG, Inc., Holdings, IBG LLC and the members of IBG LLC consummated a series of transactions collectively referred to herein as the ‘‘Recapitalization.’’ In connection with the Recapitalization, IBG, Inc., Holdings and the historical members of IBG LLC entered into an exchange agreement, dated as of May 3, 2007 (the ‘‘Exchange Agreement’’), under which the historical members of IBG LLC received membership interests in Holdings in exchange for their membership interests in IBG LLC. Additionally, IBG, Inc. became the sole managing member of IBG LLC. In connection with the consummation of the IPO, Holdings used the net proceeds to redeem 10.0% of members’ interests in Holdings in proportion to their interests. Immediately following the Recapitalization and IPO, Holdings owned approximately 90% of IBG LLC and 100% of IBG, Inc.’s Class B common stock. Since the consummation of the IPO and Recapitalization, IBG, Inc.’s equity capital structure has been comprised of Class A and Class B common stock. All shares of common stock have a par value of $0.01 per share and have identical rights to earnings and dividends and in liquidation. As of December 31, 2023 and 2022, 1,000,000,000 shares of Class A common stock were authorized, of which 107,178,928 and 103,057,148 shares have been issued; and 107,045,894 and 102,887,728 shares were outstanding, respectively. Class B common stock is comprised of 100 authorized shares, of which 100 shares were issued and outstanding as of December 31, 2023 and 2022. In addition, 10,000 shares of preferred stock have been authorized, of which no shares are issued or outstanding as of December 31, 2023 and 2022. 87 4. Equity and Earnings per Share (Continued) As a result of a federal income tax election made by IBG LLC applicable to the acquisition of IBG LLC member interests by IBG, Inc., the income tax basis of the assets of IBG LLC acquired by IBG, Inc. have been adjusted based on the amount paid for such interests. Deferred tax assets were recorded as of the IPO date and in connection with subsequent redemptions of Holdings member interests in exchange for common stock. These deferred tax assets are included in other assets in the Company’s consolidated statements of financial condition and are being amortized as additional deferred income tax expense over 15 years from the IPO date and from the additional redemption dates, respectively, as allowable under current tax law. As of December 31, 2023 and 2022, the unamortized balance of these deferred tax assets was $197 million and $193 million, respectively. IBG, Inc. also entered into an agreement (the ‘‘Tax Receivable Agreement’’) with Holdings to pay Holdings (for the benefit of the former members of IBG LLC) 85% of the tax savings that IBG, Inc. actually realizes as the result of tax basis increases. These payables to Holdings are reported as payable to affiliate in the Company’s consolidated statements of financial condition. The remaining 15% is accounted for as a permanent increase to additional paid-in capital in the Company’s consolidated statements of financial condition. The cumulative amounts of deferred tax assets, payables to Holdings and additional paid-in capital arising from stock offerings from the date of the IPO through December 31, 2023 were $682 million, $580 million and $102 million, respectively. Amounts payable under the Tax Receivable Agreement are payable to Holdings annually following the filing of IBG, Inc.’s federal income tax return. The Company has paid Holdings a cumulative total of $268 million through December 31, 2023 under the terms of the Tax Receivable Agreement. The Exchange Agreement, as amended, provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. On an annual basis, members of Holdings can request redemption of their interests. At the time of IBG, Inc.’s IPO in 2007, three hundred sixty (360) million shares of authorized common stock were reserved for future sales and redemptions. From 2008 through 2010, Holdings redeemed 5,013,259 IBG LLC interests with a total value of $114 million, which redemptions were funded using cash on hand at IBG LLC. Upon cash redemption, these IBG LLC interests were retired. From 2011 through 2022, IBG, Inc. issued 37,478,697 shares of common stock (with a fair value of $1.7 billion) directly to Holdings in exchange for an equivalent number of member interests in IBG LLC. On July 27, 2023, the Company filed a Prospectus Supplement on Form 424B5 (File Number 333-273451) with the SEC to issue 2,632,748 shares of common stock (with a fair value of $229 million) in exchange for an equivalent number of shares of member interests in IBG LLC. On July 26, 2023, the Company filed a Prospectus Supplement on Form 424B (File Number 333-273451) with the SEC to re-register up to 630,000 shares of common stock, offering the opportunity for eligible persons to receive awards in the form of an offer to receive such shares by participating in one or more promotions that are designed to attract new customers to the Company’s brokerage platform, increase assets held with the Company’s brokerage business and enhance customer loyalty. From 2019 through 2023, the Company issued 420,000 shares and an additional 50,000 shares in January 2024 to IBG LLC for distribution to eligible customers of certain of its subsidiaries. As a consequence of these redemption transactions and distribution of shares to employees (see Note 10), IBG, Inc.’s interest in IBG LLC has increased to approximately 25.4%, with Holdings owning the remaining 74.6% as of December 31, 2023. The redemptions also increased the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 84.6% at the IPO to approximately 91.3% as of December 31, 2023. 88 4.

Financial Assets and Financial Liabilities (Continued) Netting of Financial Assets and Financial Liabilities The Company’s policy is to net securities borrowed and securities loaned, and securities purchased under agreements to resell and securities sold under agreements to repurchase that meet the offsetting requirements prescribed in ASC Topic 210-20. In the tables below, the amounts of financial instruments that are not offset in the consolidated statements of financial condition, but could be netted against cash or financial instruments with specific counterparties under master netting agreements, according to the terms of the agreements, including clearing houses (exchange-traded options, warrants and discount certificates) or over the counter currency forward contract counterparties, are presented to provide financial statement readers with the Company’s net payable or receivable with counterparties for these financial instruments.

In addition, the Company’s customers pledge their securities owned to collateralize margin loans. Under these transactions, the Company either receives or provides collateral, including equity, corporate debt and U.S. government securities. Under typical agreements, the Company is permitted to sell or repledge securities received as collateral and use these securities to secure securities purchased under agreements to resell, enter into securities lending transactions or deliver these securities to counterparties to cover short positions. The Company also engages in securities financing transactions with and for customers through margin lending. Customer receivables generated from margin lending activity are collateralized by customer-owned securities held by the Company. Customers’ required margin levels and established credit limits are monitored continuously by risk management staff using automated systems. Pursuant to the Company’s policy and as enforced by such systems, customers are required to deposit additional collateral or reduce positions, when necessary, to avoid automatic liquidation of their positions. Margin loans are extended to customers on a demand basis and are not committed facilities. Factors considered in the acceptance or rejection of margin loans are the amount of the loan, the degree of leverage being employed in the customer account and an overall evaluation of the customer’s portfolio to ensure proper diversification or, in the case of concentrated positions, appropriate liquidity of the underlying collateral. Additionally, transactions relating to concentrated or restricted positions are limited or prohibited by raising the level of required margin collateral (to 100% in the extreme case). The underlying collateral for margin loans is evaluated with respect to the liquidity of the collateral positions, valuation of securities, volatility analysis and an evaluation of industry concentrations. Adherence to the Company’s collateral policies significantly limits the Company’s credit exposure to margin loans in the event of a customer’s default. Under margin lending agreements, the Company may request additional margin collateral from customers and may sell securities that have not been paid for or purchase securities sold but not delivered from customers, if necessary. As of December 31, 2023 and 2022, approximately $44.5 billion and $38.8 billion, respectively, of customer margin loans were outstanding. 96 7.

Revenues from Contracts with Customers Revenue from contracts with customers is recognized when, or as, the Company satisfies its performance obligations by transferring the promised services to the customers. A service is transferred to a customer when, or as, the customer obtains control of that service. A performance obligation may be satisfied at a point in time or over time. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that the Company determines the customer obtains control over the promised service. Revenue from a performance obligation satisfied over time is recognized by measuring the Company’s progress in satisfying the performance obligation in a manner that depicts the transfer of the services to the customer. The amount of revenue recognized reflects the consideration the Company expects to receive in exchange for those promised services (i.e., the ‘‘transaction price’’). In determining the transaction price, the Company considers multiple factors, including the effects of variable consideration, if any. The Company’s revenues from contracts with customers are recognized when the performance obligations are satisfied at an amount that reflects the consideration expected to be received in exchange for such services. The majority of the Company’s performance obligations are satisfied at a point in time and are typically collected from customers by debiting their brokerage account with the Company. Nature of Services The Company’s main sources of revenues from contracts with customers are as follows: • Commissions are charged to customers for order execution services and trade clearing and settlement services. These services represent a single performance obligation as the services are not separately 97 8. Revenues from Contracts with Customers (Continued) identifiable in the context of the contract. The Company recognizes revenue at a point in time at the execution of the order (i.e., trade date). Commissions are generally collected from cleared customers on trade date and from non-cleared customers monthly. Commissions also include payments for order flow received from IBKR LiteSM liquidity providers. • Market data fees are charged to customers for market data services to which they subscribe that the Company delivers. The Company recognizes revenue monthly as the performance obligation is satisfied over time by continually providing market data for the period. Market data fees are collected monthly, generally in advance. • • • Risk exposure fees are charged to customers who carry positions with a market risk that exceeds defined thresholds. The Company recognizes revenue daily as the performance obligation is satisfied at a point in time by the Company taking on the additional risk of account liquidation and potential losses due to insufficient margin. Risk exposure fees are collected daily. Payments for order flow are earned from various options exchanges based upon options trading volume originated by the Company that meets certain criteria. The Company recognizes revenue daily as the performance obligation is satisfied at a point in time on customer orders that qualify for payments subject to exchange-mandated programs. Payments for order flow are collected monthly, in arrears. FDIC sweep fees are earned from the banks that participate in the Company’s Insured Bank Deposit Sweep Program with respect to the Company’s customers’ funds deposited with each participating bank. The Company recognizes revenue daily as the performance obligation is satisfied when customer funds are swept to their FDIC insured accounts with the participating banks. • Minimum activity fees are charged to customers that do not generate the required minimum monthly commission. The Company recognizes revenue monthly as the performance obligation is satisfied at a point in time by servicing customer accounts that do not generate the required minimum monthly commissions. Minimum activity fees are collected monthly, in arrears. Effective July 1, 2021, the Company eliminated minimum activity fees for most account types. The Company also earns revenues from other services, including order cancelation or modification fees, position transfer fees, telecommunications fees, and withdrawal fees, among others.

Revenues from Contracts with Customers (Continued) Receivables and Contract Balances Receivables arise when the Company has an unconditional right to receive payment under a contract with a customer and are derecognized when the cash is received. Receivables of $26 million and $17 million, as of December 31, 2023 and 2022, respectively, are reported in other assets in the consolidated statements of financial condition. Contract assets arise when the revenue associated with the contract is recognized before the Company’s unconditional right to receive payment under a contract with a customer (i.e., unbilled receivable) and are derecognized when either it becomes a receivable or the cash is received. Contract assets, if any, are reported in other assets in the consolidated statements of financial condition. As of December 31, 2023 and 2022, there were no contract asset balances outstanding. Contract liabilities arise when customers remit contractual cash payments in advance of the Company satisfying its performance obligations under the contract and are derecognized when the revenue associated with the contract is recognized either when a milestone is met triggering the contractual right to bill the customer or when the performance obligation is satisfied. Contract liabilities, if any, are reported in accounts payable, accrued expenses and other liabilities in the consolidated statements of financial condition. As of December 31, 2023 and 2022, there were no contract liability balances outstanding. 9.

Employee Incentive Plans Defined Contribution Plan The Company offers substantially all employees of U.S.-based operating subsidiaries who have met minimum service requirements the opportunity to participate in defined contribution retirement plans qualifying under the provisions of Section 401(k) of the Internal Revenue Code. The general purpose of this plan is to provide employees with an incentive to make regular savings in order to provide additional financial security during retirement. This plan provides for the Company to match 50% of the employees’ pre-tax contribution, up to a maximum of 10% of eligible earnings. The employee is vested in the matching contribution incrementally over six years of service. Included in employee compensation and benefits expenses in the consolidated statements of comprehensive income were $7 million, $6 million and $5 million of plan contributions for the years ended December 31, 2023, 2022, and 2021, respectively. 2007 Stock Incentive Plan On February 28, 2023, the Company amended the 2007 Stock Incentive Plan to increase the number of shares of Class A common stock authorized and reserved for issuance from 30 million to 40 million, which was approved by the Company’s stockholders at its 2023 Annual Meeting held on April 20, 2023, and the shares were registered with the SEC on July 27, 2023. Under the Company’s Stock Incentive Plan, up to 40 million shares of 99 10. Employee Incentive Plans (Continued) the Company’s Class A common stock may be issued to satisfy vested restricted stock units granted to directors, officers, employees, contractors and consultants of the Company. The purpose of the Stock Incentive Plan is to promote the Company’s long-term financial success by attracting, retaining and rewarding eligible participants. As a result of the Company’s organizational structure, a description of which can be found in ‘‘Business – Organizational Structure’’ in Part I, Item I of this Annual Report on Form 10-K, there is no material dilutive effect upon ownership of common stockholders of issuing shares under the Stock Incentive Plan. The issuances do not dilute the book value of the ownership of common stockholders since the restricted stock units are granted at market value, and upon their vesting and the related issuance of shares of common stock, the ownership of IBG, Inc. in IBG LLC, increases proportionately to the shares issued. As a result of such proportionate increase in share ownership, the dilution upon issuance of common stock is borne by IBG LLC’s majority member (i.e., noncontrolling interest), Holdings, and not by IBG, Inc. or its common stockholders. Additionally, dilution of earnings that may take place after issuance of common stock is reflected in EPS reported in the Company’s financial statements. The EPS dilution can be neither estimated nor projected, but historically it has not been material. The Stock Incentive Plan is administered by the Compensation Committee of the Company’s Board of Directors. The Compensation Committee has discretionary authority to determine the eligibility to participate in the Stock Incentive Plan and establishes the terms and conditions of the awards, including the number of awards granted to each participant and all other terms and conditions applicable to such awards in individual grant agreements. Awards are expected to be made primarily through grants of restricted stock units. Stock Incentive Plan awards are subject to issuance over time. All previously granted but not yet earned awards may be canceled by the Company upon the participant’s termination of employment or violation of certain applicable covenants before issuance, unless determined otherwise by the Compensation Committee. The Stock Incentive Plan provides that, upon a change in control, the Compensation Committee may, at its discretion, fully vest any granted but not yet earned awards under the Stock Incentive Plan, or provide that any such granted but not yet earned awards will be honored or assumed, or new rights substituted by the new employer on a substantially similar basis and terms and conditions substantially comparable to those of the Stock Incentive Plan. The Company expects to continue to grant awards on or about December 31 of each year to eligible participants as part of an overall plan of equity compensation. In 2021, the Company’s Compensation Committee approved a change to the vesting schedule for the Stock Incentive Plan. For awards granted on December 31, 2021 onwards, restricted stock units vest and become distributable to participants 20% on each vesting date, which is on or about May 9 of each year, assuming continued employment with the Company and compliance with non-competition and other applicable covenants. The vesting and distribution of grants prior to December 31, 2021 remain in accordance with the following schedule: (a) 10% on the first vesting date, which is on or about May 9 of each year; and (b) an additional 15% on each of the following six anniversaries of the first vesting. Awards granted to directors vest and are distributed as follows: (a) one-time award granted to external directors on December 31 of the year of appointment vests over a five-year period (20% per year) commencing one year after the date of grant, and (b) annual awards granted to all directors on December 31 of each year are fully vested and distributed immediately on grant date. A total of 39,025 restricted stock units have been granted to the directors cumulatively since the plan’s inception. 100 10.

(2) Stock Incentive Plan number of granted restricted stock units related to 2022 was adjusted by 3,722 additional restricted stock units during the year ended December 31, 2023. Estimated future grants under the Stock Incentive Plan are accrued for ratably during each year (see Note 2). In accordance with the vesting schedule, outstanding awards vest and are distributed to participants yearly on or about May 9 of each year. At the end of each year, no vested awards remain undistributed. Compensation expense related to the Stock Incentive Plan recognized in the consolidated statements of comprehensive income was $100 million, $92 million and $80 million for the years ended December 31, 2023, 2022, and 2021, respectively. Estimated future compensation costs for unvested awards, net of credits for canceled awards, as of December 31, 2023 are $42 million.

Employee Incentive Plans (Continued) Awards previously granted but not yet earned under the stock plans are subject to the plans’ post-employment provisions in the event a participant ceases employment with the Company. Through December 31, 2023, a total of 1,320,900 restricted stock units have been distributed under these post-employment provisions. These distributions are included in the table above. 11. Income Taxes Income tax expense for the three years ended December 31, 2023, 2022, and 2021 differs from the U.S. federal statutory rate primarily due to the taxation treatment of income attributable to noncontrolling interests in IBG LLC. These noncontrolling interests are held directly through a U.S. partnership. Accordingly, the income attributable to these noncontrolling interests is reported in the consolidated statements of comprehensive income, but the related U.S. income tax expense attributable to these noncontrolling interests is not reported by the Company as it is generally the obligation of the noncontrolling interests. Income tax expense is also affected by the differing effective tax rates in foreign, state and local jurisdictions where certain of the Company’s subsidiaries are subject to corporate taxation. Deferred income taxes arise primarily due to the amortization of the deferred tax assets recognized in connection with the common stock offerings (see Note 4), differences in the valuation of financial assets and liabilities, and for other temporary differences arising from the deductibility of compensation and depreciation expenses in different periods for accounting and income tax return purposes. Under U.S. GAAP, the Company is allowed to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to global intangible low tax income as a current-period expense when incurred (the ‘‘period cost method’’) or (2) factoring such amounts into the Company’s measurement of its deferred taxes (the ‘‘deferred method’’).

The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. As of December 31, 2023, the Company is no longer subject to U.S. Federal and State income tax examinations for tax years before 2016, and to non-U.S. income tax examinations for tax years prior to 2012. As of December 31, 2023, accumulated earnings held by non-U.S. subsidiaries totaled $2.7 billion (as of December 31, 2022 $1.9 billion), of which $2.4 billion of such earnings are indefinitely reinvested abroad due to regulatory and other capital requirements in foreign jurisdictions. As a result, the Company has not provided for its proportionate share of additional foreign taxes or deferred U.S. tax on Internal Revenue Code (‘‘IRC’’) Section 986 gains/losses on previously taxed earnings and any local foreign withholding taxes associated with the repatriation of such earnings. If the Company were to record a deferred tax liability due to a hypothetical repatriation of such earnings, the estimated amount of such taxes would be up to $16 million of foreign withholding taxes as of December 31, 2023. Under U.S. GAAP, a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Based upon the Company’s review of its federal, state, local and foreign income tax returns and tax filing positions, the Company has recorded a $2 million tax liability for an uncertain tax position for an IRS audit primarily related to the IRC Section 199 Domestic Production Activities Deduction. 103 12. Leases All of the Company’s leases are classified as operating leases and primarily consist of real estate leases for corporate offices, data centers and other facilities. As of December 31, 2023, the weighted-average remaining lease term on these leases is approximately 6 years and the weighted-average discount rate used to measure the lease liabilities is approximately 3.73%. For the year ended December 31, 2023, right-of-use assets obtained under new operating leases were $28 million. The Company’s lease agreements do not contain any residual value guarantees, restrictions, or covenants.

Amortization expense related to the Company’s intangible assets as of December 31, 2023 is expected to be approximately $24 million, $15 million, and $4 million, for years ended December 31, 2024, 2025, and 2026, respectively. 14. Commitments, Contingencies and Guarantees Legal, Regulatory and Governmental Matters The Company is subject to certain pending and threatened legal, regulatory and governmental actions and proceedings that arise out of the normal course of business. Given the inherent difficulty of predicting the outcome of such matters, particularly in proceedings where claimants seek substantial or indeterminate damages, or which are in their early stages, the Company is generally not able to quantify the actual loss or range of loss related to such legal proceedings, the manner in which they will be resolved, the timing of their final resolution or the ultimate settlement. Management believes that the resolution of these matters will not have a material effect, if any, on the Company’s business or financial condition, but may have a material impact on the results of operations for a given period. The Company accounts for potential losses related to litigation in accordance with FASB ASC Topic 450, ‘‘Contingencies.’’ As of December 31, 2023 and 2022, accruals for potential losses related to legal, regulatory and governmental actions and proceedings matters were not material. Trading Technologies Matter As previously disclosed, on February 3, 2010, Trading Technologies International, Inc. (‘‘Trading Technologies’’) filed a complaint in the U.S. District Court for the Northern District of Illinois, Eastern Division (the ‘‘District Court’’), against IBG LLC and IB LLC (the ‘‘Defendants’’). The complaint, as amended, alleged that the Defendants infringed twelve U.S. patents held by Trading Technologies, and sought damages and injunctive relief. After proceedings before the United States Patent and Trademark Office Patent Trial Appeal Board, and review by the United States Court of Appeals for the Federal Circuit, all but four patents were found to be invalid. In June 2021, the District Court found two of the remaining four patents to be invalid, and trial on the two remaining patents began on August 6, 2021. On September 7, 2021, the jury rendered its verdict, finding that the Defendants infringed the two patents and awarding $6.6 million in damages to Trading Technologies, while 105 14. Commitments, Contingencies and Guarantees (Continued) rejecting Trading Technologies’ claims of willful infringement and request for damages of at least $962.4 million. On January 11, 2022, the District Court awarded Trading Technologies pre-judgment interest of $2.1 million and post-judgment interest, and on March 31, 2022, granted Trading Technologies’ bill of costs of $490,232. On March 24, 2022, Harris Brumfield, the successor-in-interest to the patents-in-suit, filed a notice of appeal with the Court of Appeals of the Federal Circuit. On April 7, 2022, the Defendants filed a notice of cross-appeal, which the Defendants subsequently dismissed. After briefing on the appeal, oral argument was held on January 8, 2024. The parties are awaiting the Federal Circuit’s decision. Class Action Matter On December 18, 2015, a former individual customer filed a purported class action complaint against IB LLC, IBG, Inc., and Thomas Frank, Ph.D., the Company’s Executive Vice President and Chief Information Officer, in the U.S. District Court for the District of Connecticut. The complaint alleges that a purported class of IB LLC’s customers were harmed by alleged ‘‘flaws’’ in the computerized system used to close out (i.e., liquidate) positions in customer brokerage accounts that have margin deficiencies. The complaint seeks, among other things, undefined compensatory damages and declaratory and injunctive relief. On September 28, 2016, the District Court issued an order granting the Company’s motion to dismiss the complaint in its entirety, without leave to amend. On September 28, 2017, the plaintiff appealed to the United States Court of Appeals for the Second Circuit. On September 26, 2018, the Court of Appeals affirmed the dismissal of plaintiff’s claims of breach of contract and commercially unreasonable liquidation but vacated and remanded back to the District Court plaintiff’s claims for negligence. The Company’s motion to dismiss plaintiff’s subsequent second amended complaint was denied on September 30, 2019. On July 14, 2022, after obtaining leave to amend his complaint, the plaintiff filed a third amended complaint. The Company’s answer and counterclaim were filed on July 26, 2022. On August 25, 2023, the Court granted plaintiff’s motion for class certification, certifying a class that consists of IB LLC account holders (with some exclusions) who had positions liquidated from December 18, 2013 to the date of trial at prices outside of a ‘‘pricing corridor’’ defined in the Court’s decision. On September 8, 2023, the Company filed a petition for permission to appeal the District Court’s class certification decision to the United States Court of Appeals for the Second Circuit, which denied the Company’s petition on December 19, 2023. The Company continues to believe that a purported class action is inappropriate given the great differences in portfolios, markets and many other circumstances surrounding the liquidation of any particular customer’s margin-deficient account. Pursuant to a District Court scheduling order, trial is tentatively scheduled to commence in 2025. IB LLC and the related defendants continue to believe that the plaintiff’s claims are deficient and intend to continue to defend themselves vigorously and, consistent with past practice, may pursue any potential claims for counsel fees and expenses incurred in defending the case. Regulatory Matters On September 29, 2023, IB LLC and Interactive Brokers Corp. (‘‘IB Corp.’’) entered into settlements with the SEC and CFTC to resolve investigations into compliance with records preservation requirements relating to business communications sent over electronic messaging channels that IB LLC and IB Corp. had not approved. Under the terms of the settlements, IB LLC and IB Corp. together paid $35 million to the SEC and $20 million to the CFTC, and agreed to cease and desist from further violations of certain records preservation requirements. As required by the settlements, IB LLC and IB Corp. have also engaged an independent compliance consultant and are implementing additional enhancements to their related compliance policies and procedures. As has been publicly reported, the SEC and CFTC have settled a number of similar investigations of other financial services firms, and are still in the process of conducting other similar investigations. IB LLC has identified a number of issues dating back to 2016 related to the Company’s compliance with sanctions regulations, predominantly transactions engaged in from countries or by entities prohibited by the Office of Foreign Assets Control (‘‘OFAC’’) of the United States Department of the Treasury. The Company has made voluntary self-disclosures to OFAC, has received additional inquiries from OFAC related to the Company’s sanctions compliance program, and is cooperating with the investigation. The Company cannot currently predict when OFAC’s investigation will conclude or the exact amount of any potential civil money penalty. The 106 14. Commitments, Contingencies and Guarantees (Continued) Company believes that, in addition to its voluntary self-disclosures and continued cooperation with OFAC, the significant investment in and improvements to the Company’s Anti-Money Laundering and Sanctions programs over the past five years will be considered as mitigating factors with respect to the matter, and that any monetary fines or restrictions will not be material to the Company’s financial results. Guarantees Certain of the operating subsidiaries provide guarantees to securities and commodities clearing houses and exchanges which meet the accounting definition of a guarantee under FASB ASC Topic 460, ‘‘Guarantees.’’ Under standard membership agreements, clearing house and exchange members are required to guarantee collectively the performance of other members. Under the agreements, if a member becomes unable to satisfy its obligations, other members would be required to meet shortfalls. In the opinion of management, the operating subsidiaries’ liability under these arrangements is not quantifiable and could exceed the cash and securities they have posted as collateral. However, the potential for these operating subsidiaries to be required to make payments under these arrangements is remote. Accordingly, no contingent liability is carried in the consolidated statements of financial condition for these arrangements. In connection with its retail brokerage business, IB LLC or other electronic brokerage operating subsidiaries perform securities and commodities execution, clearance and settlement on behalf of their customers for whom they commit to settle trades submitted by such customers with the respective clearing houses. If a customer fails to fulfill its settlement obligations, the respective operating subsidiary must fulfill those settlement obligations. No contingent liability is carried on the consolidated statements of financial condition for such customer obligations. Other Commitments Certain clearing houses, clearing banks and firms used by certain operating subsidiaries are given a security interest in certain assets of those operating subsidiaries held by those clearing organizations. These assets may be applied to satisfy the obligations of those operating subsidiaries to the respective clearing organizations. 15. Geographic Information The Company operates its automated global business in the U.S. and international markets on more than 150 electronic exchanges and market centers. A significant portion of the Company’s net revenues is generated by subsidiaries operating outside the U.S. International operations are conducted in 33 countries in Europe, Asia/Pacific and the Americas (outside the U.S.). The following table presents total net revenues and income before income taxes by geographic area for the periods indicated. Significant transactions and balances between the operating subsidiaries occur, primarily as a result of certain operating subsidiaries holding exchange or clearing organization memberships, which are utilized to provide execution and clearing services to subsidiaries. Intra-region income and expenses and related balances have been eliminated in this geographic information to reflect the external business conducted in each geographic region. The geographic analysis presented below is based on the location of the subsidiaries in which the transactions are recorded.

Also, certain operating subsidiaries are subject to other regulatory restrictions and requirements. As of December 31, 2023, all regulated operating subsidiaries were in compliance with their respective regulatory capital requirements. 17. Related Party Transactions Receivable from affiliate, reported in other assets in the consolidated statements of financial condition, represents amounts advanced to Holdings and payable to affiliate represents amounts payable to Holdings under the Tax Receivable Agreement (see Note 4). Included in receivables from and payables to customers in the consolidated statements of financial condition as of December 31, 2023 and 2022 were accounts receivable from directors, officers and their affiliates of $6 million and $17 million, respectively, and payables of $985 million and $1,208 million, respectively. The Company may extend credit to these related parties in connection with margin and securities loans. Such loans are (i) made in the ordinary course of business, (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the company, and (iii) do not involve more than the normal risk of collectability or present other unfavorable features. 18. Senior Notes Payable IBG LLC from time to time may offer senior notes in private placements to certain qualified customers of IB LLC at an issue price of $1 thousand per note. The senior notes will mature no later than the thirtieth day following the issuance date. IBG LLC, at its option, may redeem the senior notes at any time, at a redemption price equal to 100% of the principal amount of the senior notes to be redeemed, plus accrued interest. The senior notes will pay a fixed rate of interest during their tenure. The interest rate is calculated by adding the benchmark rate to a rate (spread) that IBG LLC will announce from time to time. The benchmark rate is the effective federal funds rate as reported by the Federal Reserve Bank of New York on the morning of the date of the offering. IBG LLC intends to use the proceeds for general financing purposes when interest spread opportunities arise. 108 18. Senior Notes Payable (Continued) The carrying value of the senior notes approximates fair value since the notes are short-term in nature.

Interest expense on the senior notes for the year ended December 31, 2023, 2022, and 2021 was $0, and $0 and $1 million, respectively. 19.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures The Company maintains disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed in the reports it files or submits under the Securities Exchange Act of 1934 (the ‘‘Exchange Act’’) is recorded, processed, summarized and reported accurately and within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer (‘‘CEO’’) and Chief Financial Officer (‘‘CFO’’), as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our CEO and our CFO, we conducted an evaluation of our disclosure controls and procedures; as such term is defined under Exchange Act Rule 13a-15(e). Based on this evaluation, our CEO and our CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this annual report. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. IBG, Inc.’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of IBG, Inc.; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of IBG, Inc.’s management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Our Accounting Policy Committee (the ‘‘APC’’) provides a robust framework for the design and implementation of all relevant controls. The APC is comprised of six (6) experienced subject matter experts from within the Company’s accounting and regulatory disciplines, and includes the CFO and the Chief Accounting Officer. The APC is responsible for assessing the effects of complex transactions and related accounting guidance on the Company’s financial statements and to report the results of its assessments to management and to the Audit Committee. The APC’s mandate includes review and approval of the adoption and implementation of accounting guidance (new or newly applicable) by the Company. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Management, including our CEO and our CFO, assessed the effectiveness of IBG, Inc.’s internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (‘‘COSO’’). Based on management’s assessment and those criteria, management concluded that IBG, Inc. maintained effective internal control over financial reporting as of December 31, 2023. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2023, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which appears herein. 110 Changes to Internal Control over Financial Reporting No changes to our internal control over financial reporting for the year ended December 31, 2023 have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Interactive Brokers Group, Inc. Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Interactive Brokers Group, Inc. and subsidiaries (the ‘‘Company’’) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements as of and for the year ended December 31, 2023, of the Company and our report dated February 26, 2024, expressed an unqualified opinion on those financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 111 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP New York, New York February 26, 2024 112 ITEM 9B.

This summary does not purport to be complete and is qualified in its entirety by the provisions of our certificate of incorporation and bylaws, copies of which are incorporated by reference as exhibits to this Annual Report on Form 10-K. When we use the terms ‘‘we,’’ ‘‘us,’’ and ‘‘our,’’ we mean solely Interactive Brokers Group, Inc. and not our subsidiaries. Our authorized capital stock consists of 1,000,000,000 shares of Class A common stock, par value $0.01 per share, 100 shares of Class B common stock, par value $0.01 per share and 10,000 shares of preferred stock. In this section, when we refer to ‘‘common stock,’’ we are referring to Class A common stock and Class B common stock, taken as a whole. Common Stock Except as otherwise provided in our organizational documents and applicable law, all shares of common stock are identical and entitle the holder to the same rights and privileges and subjects them to the same limitations and restrictions. The principle difference between the Class A and Class B common stock concerns relative voting rights. Class A common stock Voting rights The holders of Class A common stock are entitled to one vote per share. Holders of shares of Class A common stock are not entitled to cumulate their votes in the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all shares of Class A common stock and Class B common stock present in person or represented by proxy, voting together as a single class. Except as otherwise provided by law, amendments to our amended and restated certificate of incorporation must be approved by a majority of the combined voting power of all shares of Class A common stock and Class B common stock, voting together as a single class. However, amendments to the amended and restated certificate of incorporation that would alter or change the powers, preferences or special rights of the Class A common stock so as to affect them adversely also must be approved by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class. Notwithstanding the foregoing, any amendment to our amended and restated certificate of incorporation to increase or decrease the authorized shares of any class of common stock (but not below the number of shares thereof then outstanding) shall be approved upon the affirmative vote of the holders of a majority of the shares of Class A common stock and Class B common stock, voting together as a single class. Dividend rights Subject to the rights of any Preferred Stock, holders of Class A common stock share ratably (based on the number of shares of common stock held) in any dividend declared by our board of directors. Dividends consisting of shares of Class A common stock may be paid only as follows: (i) shares of Class A common stock may be paid only to holders of shares of Class A common stock; and (ii) shares are paid proportionally with respect to each outstanding share of Class A common stock. We may not subdivide or combine shares of either class of common stock without at the same time proportionally subdividing or combining shares of the other class. Dividends payable to holders of Class B common stock can only be paid if dividends in the same amount per share are simultaneously paid to holders of Class A common stock. Liquidation rights On our liquidation, dissolution or winding up and subject to the rights of any Preferred Stock, all holders of Class A common stock are entitled to share ratably in any assets available for distribution to holders of shares of common stock. 1 Other matters In accordance with the amended and restated limited liability company agreement pursuant to which IBG LLC is governed, we intend to keep the number of outstanding IBG LLC membership interests owned by us equal to the number of outstanding shares of our common stock at all times. This means that as we issue additional shares of our common stock we would expect to use the proceeds to acquire a corresponding number of shares in IBG LLC. To the extent this occurs, existing common stockholders experience no material dilution with regard to their equity interest in IBG LLC as a result of the issuance of additional shares of our common stock. In the event of our merger or consolidation with or into another company in connection with which shares of either class of common stock are converted into or exchangeable for shares of stock, other securities or property (including cash), all holders of common stock, regardless of class, are entitled to receive the same kind and amount of shares of stock and other securities and property (including cash), provided that if shares of either class of common stock are exchanged for shares of capital stock, such shares exchanged for or changed into may differ to the extent that the Class A common stock and the Class B common stock differ. No shares of either class of common stock are subject to redemption or have preemptive rights to purchase additional shares of either class of common stock. All outstanding shares of Class A common stock have been legally issued, fully paid and nonassessable. Class B common stock Voting rights The holders of Class B common stock, in the aggregate, are entitled to the number of votes equal to the number of IBG LLC membership interests held by such holders. IBG Holdings LLC, as the sole holder of the Class B common stock, is entitled to approximately 314 million votes, as of December 31, 2023. Holders of shares of Class B common stock are not entitled to cumulate their votes in the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all shares of Class B common stock and Class A common stock present in person or represented by proxy, voting together as a single class. Except as otherwise provided by law, amendments to the amended and restated certificate of incorporation must be approved by a majority of the combined voting power of all shares of Class B common stock and Class A common stock, voting together as a single class. However, amendments to the certificate of incorporation that would alter or change the powers, preferences or special rights of the Class B common stock so as to affect them adversely also must be approved by a majority of the votes entitled to be cast by the holders of the shares affected by the amendment, voting as a separate class. Notwithstanding the foregoing, any amendment to our amended and restated certificate of incorporation to increase or decrease the authorized shares of any class of common stock (but not below the number of shares thereof then outstanding) shall be approved upon the affirmative vote of the holders of a majority of the shares of Class B common stock and Class A common stock, voting together as a single class. Dividend rights Subject to the rights of any Preferred Stock, holders of Class B common stock share ratably (based on the number of shares of common stock held) in any dividend declared by the board of directors. Dividends consisting of shares of Class B common stock may be paid only as follows: (i) shares of Class B common stock may be paid only to holders of shares of Class B common stock; and (ii) shares are paid proportionally with respect to each outstanding share of Class B common stock. We may not subdivide or combine shares of either class of common stock without at the same time proportionally subdividing or combining shares of the other class. Dividends payable to holders of Class B common stock can only be paid if dividends in the same amount per share are simultaneously paid to holders of Class A common stock. Liquidation rights On our liquidation, dissolution or winding up and subject to the rights of any Preferred Stock, all holders of Class B common stock are entitled to share ratably in any assets available for distribution to holders of shares of common stock. 2 Other matters In the event of our merger or consolidation with or into another company in connection with which shares of either class of common stock are converted into or exchangeable for shares of stock, other securities or property (including cash), all holders of common stock, regardless of class, are entitled to receive the same kind and amount of shares of stock and other securities and property (including cash), provided that, if shares of either class of common stock are exchanged for shares of capital stock, such shares exchanged for or changed into may differ to the extent that the Class A common stock and the Class B common stock differ. No shares of either class of common stock are subject to redemption or will have preemptive rights to purchase additional shares of either class of common stock. All outstanding shares of Class B common stock have been legally issued and are fully paid and nonassessable. Preferred Stock Our board of directors has the authority, without further action by our stockholders, to issue our preferred stock in one or more series and to fix the rights, preferences, privileges, and restrictions thereof. These rights, preferences, and privileges include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms, and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of our common stock. The issuance of our preferred stock could adversely affect the voting power of our holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of our preferred stock could have the effect of delaying, deferring, or preventing a change in our control. Anti-takeover Effects of the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws Certain provisions of our amended and restated certificate of incorporation and our bylaws could have anti-takeover effects. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our corporate policies formulated by our board of directors. In addition, these provisions also are intended to ensure that our board of directors will have sufficient time to fulfill its fiduciary duties to us and our stockholders. These provisions also are designed to reduce our vulnerability to an unsolicited proposal for our takeover that does not contemplate the acquisition of all of our outstanding shares or an unsolicited proposal for the restructuring or sale of all or part of us. The provisions are also intended to discourage certain tactics that may be used in proxy fights. However, these provisions could delay or frustrate the removal of incumbent directors or the assumption of control of us by the holder of a large block of common stock, and could also discourage or make more difficult a merger, tender offer, or proxy contest, even if such event would be favorable to the interest of our stockholders. Special meetings of stockholders. Our bylaws preclude our stockholders from calling special meetings of stockholders or requiring the board of directors or any officer to call such a meeting or from proposing business at such a meeting. Our bylaws provide that only a majority of our board of directors, the chairman of the board or the chief executive officer can call a special meeting of stockholders. Because our stockholders do not have the right to call a special meeting, a stockholder cannot force stockholder consideration of a proposal over the opposition of the board of directors by calling a special meeting of stockholders prior to the time a majority of the board of directors, the chairman of the board or the chief executive officer believes the matter should be considered or until the next annual meeting provided that the requestor met the notice requirements. The restriction on the ability of stockholders to call a special meeting means that a proposal to replace board members also can be delayed until the next annual meeting. Other limitations on stockholder actions. Advance notice is required for stockholders to nominate directors or to submit proposals for consideration at meetings of stockholders. This provision may have the effect of precluding the conduct of certain business at a meeting if the proper notice is not provided and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company. In addition, the ability of our stockholders to remove directors without cause is precluded. 3 Section 203 of the General Corporation Law of the State of Delaware We are subject to Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that such stockholder became an interested stockholder, with the following exceptions: • • • prior to such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder; upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; and on or subsequent to such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 662/3% of the outstanding voting stock that is not owned by the interested stockholder. Section 203 defines business combination to include the following (each as more particularly described under Delaware law): • • • • • any merger or consolidation involving the corporation and the interested stockholder; any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder; subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges, or other financial benefits by or through the corporation. In general, Section 203 defines an interested stockholder as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation or any entity or person affiliated with or controlling or controlled by such entity or person. Transfer Agent and Registrar The transfer agent and registrar for shares of our common stock is Computershare Shareholder Services, Inc. Listing Our common stock is listed on The Nasdaq Stock Market LLC’s Global Select Market under the symbol ‘‘IBKR.’’ 4 Exhibit 19.1 INSIDER TRADING POLICES AND PROCEDURES I. OVERVIEW All employees of Interactive Brokers Group, Inc. and its direct and indirect subsidiaries (collectively, the ‘‘Group’’) have a continuing obligation to: (i) comply with all applicable laws and regulations related to securities trading, including the prohibition against trading based on material non-public information; (ii) disclose any trading activity undertaken in securities or commodities accounts under their control or in which they or their families have any interest, and; (iii) refrain from engaging in any trading or investing activity that conveys, or appears to convey, a personal benefit to an employee related to a Group action over which the employee had influence. The following explains the various regulatory requirements to which Group affiliates and their employees are subject, and the requirements, obligations and restrictions applicable to the Group and its employees. II. REGULATORY REQUIREMENTS Group affiliates are subject to the rules and regulations of the various national, state and/or provincial government regulators of a variety of jurisdictions globally, as well as of the Self- Regulatory Organizations of which they are members (collectively, ‘‘Regulatory Authorities’’). Certain Regulatory Authorities require the monitoring and/or reporting of employee trading activity in order to identify trades that may violate the prohibitions on insider trading and/or manipulative or deceptive practices. Such prohibitions include trading on the basis of information relating to the trading activities of Group. The rules require that firms review all trades effected for the accounts of exchange members or employees and their families. For these purposes, ‘‘employee accounts’’ include any account in which an Employee has an interest or has the power, directly or indirectly, to make investment decisions and ‘‘family member accounts’’ include accounts of the following: • • • • an employee’s spouse; children of employees and the children’s spouses, provided that they reside in the same household with, or are financially dependent upon the employee; any other related individual over whose account the employee has control or financial interest in; and any other individual over whose account the employee has control and to whose financial support the employee materially contributes. III. ACCOUNT DISCLOSURE In order to comply with the requirements of the Regulatory Authorities, Group employees must disclose all ‘‘employee accounts’’ and ‘‘family member accounts,’’ and must arrange for the Group to receive duplicate copies of all account statements for the trading activity in these accounts. (Copies should be sent directly from the brokerage firm to the Group. The enclosed form letter should be completed and returned to the Compliance Department, where it will be signed and forwarded to the brokerage firm.) Each Group employee is under a continuing obligation to immediately advise the Group prior to establishing any new trading account by providing the information requested on the attached form, and returning it signed and dated to the Compliance Department within one week of receipt. Each Group employee is also under a continuing obligation to immediately notify the Group if the employee closes an existing trading account. Periodically, the Group will remind Group employees to review the trading account information that the Group has on file and confirm whether such information is accurate or needs to be revised. Group employees must receive consent from the Group Compliance Department prior to participating in private securities transactions (e.g., private placement offerings). Please note that any false or misleading statements made to the Group are cause for immediate termination of employment. IV. INSIDER TRADING IS PROHIBITED AND UNLAWFUL The Group forbids any officer, director or employee from trading based on material non-public information, or communicating material non-public information to others in violation of the law. The law concerning insider trading prohibits: • • • trading by an insider, either personally or on behalf of others, while in possession of material nonpublic information; trading by a non-insider, while in possession of material nonpublic information; or communicating material nonpublic information to others. Penalties for trading on or communicating material nonpublic information are severe, both for individuals involved in such unlawful conduct and potentially their employers. Identifying Inside Information: Before considering trading for yourself or others in the securities of a company about which you may have potential inside information, consider (and if unsure seek guidance from Compliance) the following questions: • • Is the information material? Is this information that an investor would consider important in making his or her investment decisions? Is this information that would substantially affect the market price of the securities if generally disclosed? Is the information nonpublic? To whom has this information been provided? Has the information been effectively communicated to the marketplace? If you believe that the information is material and nonpublic, or if you have any questions as to whether the information is material and nonpublic, you should take the following steps: 1. Report the matter immediately to your Chief Compliance Officer (‘‘CCO’’). 2. Do not use the information to purchase or sell the securities on behalf of yourself or others, including customer accounts carried by the Firm. 3. Do not communicate the information inside or outside IB Group, other than to the CCO. After IB Group management has reviewed the issue, you will be given appropriate guidance. V. RESTRICTION ON TRADING RELATED TO IB GROUP ACTIONS Group officers, directors and employees who have any knowledge, role in, or influence over a Group decision to take an action (other than one required by law, rule or regulation) that could affect the market price of any security or investment product are prohibited from engaging in trading related to such security or investment product for such period of time as the action taken could affect pricing. The purpose of this policy is to ensure no Group employee can personally benefit, or even create the perception of deriving personal benefit, from a Group action over which the employee had influence or knowledge. This prohibition applies even after the action is publicly disclosed. For example, an employee involved in a Group decision to limit Group trading of a particular security or category of securities is prohibited from engaging in trading related to such security or securities so long as the Group limitation is in place. VI. ADDITIONAL TRADING RESTRICTIONS: 1. Restrictions Applicable to Employees who trade on behalf of IBKR: Employees with knowledge of pending IBKR trading that could affect the market price of any security or investment product are prohibited from engaging in trading related to such security or investment product so long as such pending activity is undisclosed and could affect pricing. 2. Restrictions Applicable to Floor Personnel. Trading floor employees are prohibited from trading in securities, commodities, derivative products, financial instruments, or other exchange traded investment products that trade at the exchange at which the employee works. 3. Restrictions Applicable to All Group Employees. Group employees may not personally trade securities, commodities, derivative products, financial instruments or exchange traded investment products on their own behalf between the hours of 8:30 a.m. and 6:00 p.m. local time at the Group employee’s place of employment (the ‘‘Prohibited Hours’’); however, with the approval of the Compliance Department of their region, Group employees may make arrangements for trading activity on their behalf during Prohibited Hours, so long as the activity does not require their personal attention or involvement during Prohibited Hours. Such approved arrangements may include, for example, retaining a Financial Advisor authorized to trade on behalf of an employee during Prohibited Hours (without requiring any communication with or action by the employee during Prohibited Hours) or use of automated trading tools that execute trades without requiring any monitoring by or attention from employee during Prohibited Hours. 4. Restrictions Applicable to Trading Interactive Brokers Group, Inc. Securities (IBKR). Group employees, officers and directors, and their spouses or significant others, children and other immediate family members who live with them (each a ‘‘Covered Person’’) may purchase or sell IBKR shares only within the ten (10) calendar day period beginning on the first U.S. business day following one full trading day after the announcement of IBKR’s final quarterly (or annual) earnings as filed with the SEC (‘‘Trading Window’’). Resulting trades must be executed within the Trading Window. Any orders that are capable of executing outside the Trading Window, e.g., ‘‘good ‘til cancelled’’ (‘‘GTC’’) orders, must be cancelled at or before the end of the Trading Window. For example, if earnings are announced on a Tuesday, then the Trading Window would begin two days later on Thursday and last until Friday of the following week (barring holidays). The foregoing restriction shall not apply to transactions made under a trading plan adopted pursuant to SEC Rule 10b5-1 (c) (a ‘‘Rule 10b5-1 Plan’’) and approved in writing by the Group Compliance Officer. Rule 10b5-1 Plans must be submitted to the Compliance Department for prior approval and may only be entered into or amended during a Trading Window. No Covered Person may (at any time, including during the Trading Window) hedge IBKR stock, sell IBKR stock short or trade IBKR-related derivative products (including without limitation equity options contracts, security futures contracts and CFDs) (collectively, ‘‘IBKR Derivatives’’). In addition, no Covered Person may buy, sell, or otherwise trade in IBKR shares or IBKR Derivatives, or tip others to trade in IBKR shares or IBKR Derivatives, while in possession of material, non-public information. If you have any question as to whether you possess material, non-public information, you must consult with Compliance. 5. Restrictions Applicable to IBG Holdings LLC Members. IBG Holdings LLC Members and their ‘‘Related Parties’’ may not under any circumstances purchase or otherwise acquire IBKR shares or IBKR Derivatives without the prior consent of the Group’s Chairman. For purposes of this item 5, ‘‘Related Parties’’ mean any family members (including spouse, siblings, ancestors, and lineal descendants or any shares or interests that are beneficially owned by you or your family members through a trust or a partnership, and any shares or interests owned by any other partner in a partnership in which you or one of your family members holds an interest). If you have any questions regarding application of the foregoing, you must consult with the Group’s Chairman. VII. PURPOSE OF GROUP TRADING POLICIES AND RESTRICTIONS: This policy is aimed at avoiding the possibility of violations of insider trading regulations and otherwise protects the Group from loss. If any employee discovers that another employee has traded without disclosure to the Group or in violation of the above trading restrictions, or believes that another person has violated, or is about to violate, the prohibition against insider trading, or otherwise engage, or is about to engage in, a manipulative or deceptive practice, such Group employee should immediately advise the Compliance Department either directly or (including for anonymous reporting) through https://interactivebrokers.ethicspoint.com. Appropriate rewards will be made to anyone who discovers and reports violations of these rules.

POLICY RELATING TO RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION Exhibit 97.1 INTERACTIVE BROKERS GROUP, INC. CLAWBACK POLICY The Board of Directors (the ‘‘Board’’) of Interactive Brokers Group, Inc. (the ‘‘Company’’) has adopted this Clawback Policy (this ‘‘Policy’’), which provides for the recovery of certain incentive compensation in the event of an Accounting Restatement (as defined below). This Policy is designed to comply with, and shall be interpreted in a manner consistent with, Section 10D of the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’), Rule 10D-1 promulgated under the Exchange Act (‘‘Rule 10D-1’’) and Rule 5608 of the Nasdaq Stock Market (‘‘NASDAQ’’) Rulebook. 1. Definitions For purposes of this Policy, the following capitalized terms shall have the meanings set forth in this Section 1: (i) ‘‘Accounting Restatement’’ means an accounting restatement of the Company’s financial statements due to the Company’s material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. (ii) ‘‘Administrator’’ means the Audit Committee of the Company’s Board of Directors or such other committee that may be appointed by the Board to administer this Policy. (iii) ‘‘Board’’ means the Company’s Board of Directors. (iv) (v) ‘‘Clawback Eligible Incentive Compensation’’ means all Incentive-Based Compensation Received by a Covered Executive (a) on or after the Effective Date that results from attainment of a Financial Reporting Measure based on or derived from financial information for any fiscal period ending on or after the Effective Date, (b) after beginning service as a Covered Executive, (c) who served as a Covered Executive at any time during the applicable performance period for the applicable Incentive-based Compensation, (d) while the Company has a class of securities listed on a national securities exchange or a national securities association and (e) during the applicable Clawback Period. ‘‘Clawback Period’’ means the three completed fiscal years immediately preceding the date on which the Company is required to prepare an Accounting Restatement, as well as any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years (except that a transition period that comprises a period of at least nine months shall count as a completed fiscal year). The ‘‘date on which the Company is required to prepare an Accounting Restatement’’ is the earlier to occur of (a) the date the Board, a committee of the Board (or the officer or officers of the Company authorized to take such action if Board action is not required) concludes, or reasonably should have concluded, that the Company is required to prepare an Accounting Restatement or (b) the date a court, regulator or other legally authorized body directs the Company to prepare an Accounting Restatement, in each case regardless of whether or when the restated financial statements are filed. (vi) ‘‘Code’’ means the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder. (vii) ‘‘Covered Executive’’ means the Company’s current and former president, principal financial officer, principal accounting officer (or if there is no such accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or finance), any other officer who performs a policy-making function, or any other person who performs similar policy-making functions for the Company. Individuals employed by one of the Company’s subsidiaries shall be deemed Covered Executives under this Policy if they perform 1 such policy making functions for the Company. For purposes of identifying Covered Executives, ‘‘policy-making’’ function is not intended to include policy-making functions that are not significant. Identification of a Covered Executive shall include at a minimum executive officers identified pursuant to 17 C.F.R. Section 229.401(b). (viii) ‘‘Effective Date’’ means December 1, 2023. (ix) ‘‘Erroneously Awarded Compensation’’ has the meaning set forth in Section 4 of this Policy. (x) ‘‘Financial Reporting Measure’’ means any measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measure. Financial Reporting Measures include but are not limited to the following (and any measures derived from the following measures): Company stock price; total shareholder return (‘‘TSR’’); revenues; net income; operating income; profitability of one or more reportable segments; financial ratios; earnings before interest, taxes, depreciation and amortization (‘‘EBITDA’’); funds from operations and adjusted funds from operations; liquidity measures (e.g., working capital, operating cash flow); return measures (e.g., return on invested capital, return on assets); earnings measures (e.g., earnings per share); revenue per user, or average revenue per user, where revenue is subject to an Accounting Restatement; cost per employee, where cost is subject to an Accounting Restatement; any of such financial reporting measures relative to a peer group, where the Company’s financial reporting measure is subject to an Accounting Restatement; and tax basis income. A metric that is used to determine an amount of compensation need not be presented within the Company’s financial statements or included in a filing with the Securities Exchange Commission in order to be considered a Financial Reporting Measure. (xi) ‘‘Incentive-Based Compensation’’ means any compensation that is granted, earned or vested based, wholly or in part, upon the attainment of a Financial Reporting Measure. (xii) Incentive-Based Compensation is ‘‘Received’’ for purposes of this Policy in the Company’s fiscal period during which the Financial Reporting Measure specified in the Incentive-Based Compensation award is attained, even if the payment or grant of such Incentive-Based Compensation occurs after the end of that period. 2. Administration The Administrator is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate or advisable for the administration of this Policy, including, without limitation, to identify the Covered Executives that are subject to this Policy. Any determinations made by the Administrator shall be final and binding on all affected individuals and need not be uniform with respect to each individual covered by this Policy. In the administration of this Policy, the Administrator is authorized and directed to consult with the full Board, the Compensation Committee of the Board or such other committees of the Board as may be necessary or appropriate as to matters within the scope of such other committee’s responsibilities and authority. Subject to any limitation of applicable law, the Administrator may authorize and empower any officer or employee of the Company to take any and all actions necessary or appropriate to carry out the purpose and intent of this Policy (other than with respect to any recovery under this Policy involving such officer or employee). 3. Required Recoupment of Erroneously Awarded Compensation in the Event of an Accounting Restatement In the event that the Company is required to prepare an Accounting Restatement, the Company shall promptly recoup the amount of any Erroneously Awarded Compensation Received by any Covered Executive, as calculated pursuant to Section 4 of this Policy, during the Clawback Period. Recovery under this Policy with respect to a Covered Executive shall not require the finding of any misconduct by such Covered Executive or any finding that such Covered Executive bore any level of responsibility for the accounting error or errors leading to the applicable Accounting Restatement. 2 4. Erroneously Awarded Compensation: Amount Subject to Recovery The amount of ‘‘Erroneously Awarded Compensation’’ subject to recovery under this Policy, as determined by the Administrator, is the amount of Clawback Eligible Incentive Compensation that exceeds the amount of Incentive-Based Compensation that otherwise would have been Received by the Covered Executive had it been determined based on the financial statements as prepared pursuant to the applicable Accounting Restatement. Erroneously Awarded Compensation shall be computed by the Administrator without regard to any taxes paid by the Covered Executive in respect of the Erroneously Awarded Compensation. With respect to any compensation plans or programs that take into account Incentive-Based Compensation, the amount of Erroneously Awarded Compensation subject to recovery hereunder includes, but is not limited to, the amount contributed to any notional account based on Erroneously Awarded Compensation and any earnings accrued to date on that notional amount. With respect to Incentive-Based Compensation based on (or derived from) the Company’s stock price or TSR, in which the amount of Erroneously Awarded Compensation is not subject to mathematical calculation directly from the information in the applicable Accounting Restatement: (a) the Administrator shall determine the amount of Erroneously Awarded Compensation based on a reasonable estimate of the effect of the Accounting Restatement on the stock price or TSR upon which the Incentive-Based Compensation was Received and (b) the Company shall maintain documentation of the determination of such reasonable estimate and shall provide such documentation to NASDAQ. 5. Method of Recoupment The Administrator shall determine, in its sole discretion, the timing and method for promptly recouping Erroneously Awarded Compensation hereunder, which may include, without limitation, (a) seeking reimbursement of all or part of any cash or equity-based award, (b) cancelling prior cash or equity-based awards, whether vested or unvested or paid or unpaid, (c) cancelling or offsetting against any planned future cash or equity-based awards, (d) forfeiture of deferred compensation, subject to compliance with Section 409A of the Code and (e) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Administrator may effect recovery under this Policy from any amount otherwise payable to the Covered Executive, including amounts payable to such individual under any otherwise applicable Company plan or program, including base salary, bonuses or commissions and compensation previously deferred by the Covered Executive. The Company is authorized and directed pursuant to this Policy to recoup Erroneously Awarded Compensation in compliance with this Policy unless the Audit Committee of the Board has determined that recovery would be impracticable solely for the following limited reasons, and subject to the following procedural and disclosure requirements: • • The direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation based on the expense of enforcement, the Administrator must make a reasonable attempt to recover such Erroneously Awarded Compensation, document such attempt(s) and to provide such documentation to NASDAQ; or Recovery would likely cause a plan that is intended to be tax-qualified under Section 401(a) of the Code, under which benefits are broadly available to employees of the Company or any of its subsidiaries, to fail to meet the requirements of Section 401(a)(13) or Section 411(a) of the Code or any regulations promulgated thereunder. 6. No Indemnification of Covered Executives Notwithstanding the terms of any indemnification or insurance policy or any contractual arrangement with any Covered Executive that may be interpreted to the contrary, the Company shall not indemnify any Covered Executives against the loss of any Erroneously Awarded Compensation, including any payment or reimbursement for the cost of third-party insurance purchased by any Covered Executives to fund potential clawback obligations under this Policy. 3 7. Administrator Indemnification Any members of the Administrator, and any other members of the Board who assist in the administration of this Policy, shall not be personally liable for any action, determination or interpretation made with respect to this Policy and shall be fully indemnified by the Company to the fullest extent under applicable law and Company policy with respect to any such action, determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the Board under applicable law or Company policy. 8. Retroactive Application The terms of this Policy shall apply to any Incentive-Based Compensation that is received by Covered Executives on or after the Effective Date, even if such Incentive-Based Compensation was approved, awarded, granted or paid to Covered Executives prior to the Effective Date. Without limiting the generality of Section 5 of this Policy, and subject to applicable law, the Administrator may effect recovery under this Policy from any amount of compensation approved, awarded, granted, payable or paid to the Covered Executive prior to, on, or after the Effective Date. This Policy shall replace and supersede any other clawback or compensation recoupment policy previously adopted or maintained by the Company or any of its subsidiaries, including any clawback rules under any applicable compensation plan, award or agreement. 9. Amendment; Termination The Board or the Administrator may amend, modify, supplement, rescind or replace all or any portion of this Policy at any time and from time to time in its discretion, and shall amend this Policy as it deems necessary to comply with applicable law or any rules or standards adopted by NASDAQ or any other national securities exchange on which the Company’s securities are listed. 10. Other Recoupment Rights; Company Claims The Board intends that this Policy shall be applied to the fullest extent of the law. Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment that may be available to the Company under applicable law or pursuant to the terms of any similar policy in any employment agreement, equity award agreement or similar agreement and any other legal remedies available to the Company. Nothing contained in this Policy, and no recoupment or recovery as contemplated by this Policy, shall limit any claims, damages or other legal remedies the Company or any of its affiliates may have against a Covered Executive arising out of or resulting from any actions or omissions by such Covered Executive. 11. Successors This Policy shall be binding and enforceable against all Covered Executives and their beneficiaries, heirs, executors, administrators or other legal representatives. 12. Governing Law; Venue This Policy and all rights and obligations hereunder are governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of laws principles of any jurisdiction. All actions arising out of or relating to this Policy shall be heard and determined exclusively in the United States District Court for the Southern District of New York or, if such court does not have valid jurisdiction over any such action, in the state courts located in New York County, New York. 13.
