• Net interest income increased 21% to $967 million on stronger securities lending activity and higher average customer margin loans and customer credit balances.

• Execution, clearing and distribution fees decreased 21% to $92 million, driven by lower regulatory fees, as the SEC Section 31 transaction fee rate was reduced to zero on May 14, 2025, and greater capture of liquidity rebates from certain exchanges due to higher trading volumes in stocks and options.

• General and administrative expenses decreased 59% to $62 million, driven primarily by the non-recurrences of $88 million related to legal and regulatory matters and of $12 million related to the consolidation of our European subsidiaries; partially offset by an increase of $10 million in advertising expenses.

In connection with our currency diversification strategy, we base our net worth in GLOBALs, a basket of 10 major currencies in which we hold our equity. In this quarter, our currency diversification strategy decreased our comprehensive earnings by $33 million, as the U.S. dollar value of the GLOBAL decreased by approximately 0.25%.

Note: The term "GAAP" in the following explanation refers to generally accepted accounting principles in the United States.

¹ Adjusted net revenues, adjusted income before income taxes, adjusted net income available for common stockholders and adjusted diluted earnings per share ("EPS") are non-GAAP financial measures.

• We define adjusted net revenues as net revenues adjusted to remove the effect of our currency diversification strategy and our net mark-to-market gains (losses) on investments².
• We define adjusted income before income taxes as income before income taxes adjusted to remove the effect of our currency diversification strategy and our net mark-to-market gains (losses) on investments.
• 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 and our net mark-to-market gains (losses) on investments.
• 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.

Management believes these non-GAAP items 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 and may be useful to investors and analysts in evaluating the operating performance of the business and facilitating a meaningful comparison of our results in the current period to those in prior and future periods. Our currency diversification strategy and our mark-to-market on investments are excluded because management does not believe they are indicative of our underlying core business performance. Adjusted net revenues, adjusted income before income taxes, adjusted net income available to common stockholders and adjusted diluted EPS should be considered in addition to, rather than as a substitute for, GAAP net revenues, income before income taxes, net income attributable to common stockholders and diluted EPS.

² 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.

³ The income tax effect is estimated using the statutory income tax rates applicable to the Company.

⁴ Prior period share and per share amounts have been retroactively adjusted to reflect the four-for-one forward stock split, effected in the form of a stock dividend, on June 17, 2025.
