Material Changes vs. Prior Period
- Revenue Growth: Net revenues increased $242 million (17%) driven by higher trading volumes and net interest income. Commission revenue rose 19% due to a 25% increase in stock volumes, 20% in futures, and 16% in options.
- Interest Rate Environment: Despite a decline in the average federal funds effective rate to 3.64% (from 4.33% in Q1 2025), net interest income grew 17% due to significantly higher average customer margin loan and credit balances.
- Expense Management: Total non-interest expenses increased only 2% to $381 million. Execution, clearing, and distribution fees decreased 12% to $106 million, primarily due to the SEC Section 31 transaction fee rate reduction to zero in May 2025 and increased liquidity rebates.
- Customer Statistics: Customer equity grew 38% year-over-year to $789.4 billion. Daily Average Revenue Trades (DARTs) increased 24% to 4.37 million.
- Currency Impact: The Company's currency diversification strategy (GLOBAL) resulted in a $53 million reduction in comprehensive earnings for the quarter due to a 0.30% decrease in the GLOBAL's value against the U.S. dollar.

Investor Verification Checklist
- Verify the impact of the SEC Section 31 fee elimination on future execution costs and commission pass-throughs.
- Monitor the Net Interest Margin (NIM) trend (1.88% in Q1 2026 vs 2.10% in Q1 2025) as interest rates remain volatile.
- Review the currency diversification strategy performance, as fluctuations in the GLOBAL basket directly impact comprehensive income.
- Assess the noncontrolling interest structure, where approximately 73.7% of IBG LLC membership interests are held by Holdings (Thomas Peterffy and affiliates), affecting the portion of net income attributable to public shareholders.
- Confirm the status of the class action settlement and potential opt-out rates that could affect the final payout amount.
