Interactive Brokers Group, Inc.

As of December 31, 2025, we had 3,182 employees in 24 cities across 16 countries. We remain committed to helping our employees thrive, enabling them to drive our business forward.

Social Initiatives

The 2025 IBKR Engagement Survey demonstrated a strong and growing culture of trust and transparency, with a 90% employee participation rate, an increase of 20% over the prior year, highlighting employees’ confidence in our commitment to meaningful progress. For the second consecutive year, the highest-rated survey question reflected employees’ strong belief in our business model, reinforcing alignment with our strategy and long-term direction. Survey results were shared openly with all employees, and a clear action plan was developed with our leaders to address common themes and feedback. At IBKR, we view employee experience as a critical priority, and the engagement survey remains an essential tool for listening to our workforce and staying closely connected to what matters most to our people.

Our Mentorship Program continues to foster connection and career development across our global workforce. The program engaged over 250 participants this year, spanning 20 locations and 30+ departments, facilitating knowledge sharing and cross-functional collaboration.

Our 10-week Summer Internship Program is a critical talent pipeline. After receiving over 12,000 applications, we hosted 53 interns at our Greenwich and Chicago offices from 34 universities. Through project work, leadership exposure, and industry training, the program consistently converts early career talent into full-time employees.

We continue to support our employees and the communities where we operate on a global scale. Our employees contribute to important causes through our corporate giving program, which is matched by IBKR.

Employee and Leadership Development

We provide all employees with learning tools that support their professional and personal growth. In 2025, our internal learning platform grew to over 1,200 on-demand courses. We enhanced our Employee Development program, allowing employees and managers to select from instructor-led training sessions tailored to their development priorities. We also provided new tools to showcase potential career pathways and job mobility opportunities.

Additionally, we launched comprehensive AI training and learning resources to equip employees with the skills to confidently and creatively leverage AI tools in their work. We expanded our financial literacy initiatives, providing employees with access to live events, educational materials, and specialized courses to support their personal financial well-being. Additionally, we maintain a comprehensive global mandatory training program covering critical areas, including Anti-Money Laundering, Sanctions and Cybersecurity, to fulfill essential operational and regulatory requirements.

Our People

Our people are fundamental to our business. We prioritize a merit-based culture and are focused on attracting, retaining, and developing a global workforce across diverse communities and geographic markets.

Our total rewards strategy is designed to deliver highly competitive compensation and benefits across our global locations, supporting the physical, emotional, and financial wellbeing of our employees. Many benefit programs are organized locally to ensure alignment with market competitive practices and statutory requirements, including medical coverage and pension plans. In addition, we offer global benefits intended to reinforce our culture and support employee engagement, including the following:

•

Stock Incentive Plan: We maintain a stock incentive plan under which we grant equity awards to employees on an annual basis. Equity-based compensation aligns employee interests with long-term performance of IBKR by linking a portion of total compensation to stock ownership and company results.

•

Global Employee Assistance Program (“EAP”): We provide employees and their families with access to a global Employee Assistance Program offering 24/7 confidential mental health and wellness support services.

•

IBKR Fit: We introduced a global fitness center benefit to support and motivate employee physical wellness.

Where applicable, we fund all or a portion of healthcare premiums to reduce the costs for employees. We provide paid parental leave for all employee parents and sponsor locally administered benefits in numerous global locations, including adoption and fertility benefits and childcare support. In addition, we support employee resource groups and internal social communities across the Company.

Sustainability

Our sustainability initiatives are driven by the strategies led by our Board and are implemented throughout the Company. In 2025, we expanded our Sustainability Report, consistent with the Task Force on Climate-Related Financial Disclosures (“TCFD”), which outlines our approach to climate related risk under governance, strategy, risk management and metrics. In addition, we expanded our assessment of Greenhouse Gas (“GHG”) under Scope 1, Scope 2 and material Scope 3 emissions and expect to present the results in our 2025 Sustainability Report.

We have procured renewable power sources for all our offices through direct renewable energy or through the purchase of renewable energy certificates. We use third-party providers for data centers. Globally, where possible, our data centers use renewable power provided directly through the landlord or via renewable energy certificates. Annually, we assess current and best practices when reviewing our efficiency measures.
