— — —

GAAP DILUTED EPS OF $0.69, ADJUSTED¹ EPS OF $0.69

GAAP NET REVENUES OF $1.90 BILLION, ADJUSTED NET REVENUES OF $1.88 BILLION

GREENWICH, CT, July 21, 2026 — Interactive Brokers Group, Inc. (Nasdaq: IBKR), an automated global broker, announced results for the quarter ended June 30, 2026.

Reported and adjusted diluted earnings per share were both $0.69 for the current quarter. For the year-ago quarter, reported and adjusted diluted earnings per share were both $0.51.

Reported net revenues were $1.90 billion for the current quarter and $1.88 billion as adjusted. For the year-ago quarter, reported and adjusted net revenues were both $1.48 billion.

Reported income before income taxes was $1.46 billion for the current quarter and $1.44 billion as adjusted. For the year-ago quarter, reported and adjusted income before income taxes were both $1.10 billion.

Financial Highlights

(All comparisons are to the year-ago quarter.)

- Commission revenue increased 30% to $673 million on higher customer trading volumes. Customer trading volume in options, stocks and futures increased 17%, 14% and 2%, respectively.
- Net interest income increased 23% to $1.06 billion primarily on higher average customer margin loans and customer credit balances.
- Other fees and services increased 40% to $87 million, led by increases of $9 million in payments for order flow from exchange-mandated programs, $8 million in risk exposure fees, and $3 million in market data fees.
- Execution, clearing and distribution fees increased 22% to $142 million, driven by a $19 million increase in regulatory fees, as the SEC Section 31 transaction fee rate increased on April 4, 2026; partially offset by greater capture of liquidity rebates from certain exchanges due to higher trading volumes in stocks and options.
- Pretax profit margin for the current quarter was 77% both as reported and as adjusted. For the year-ago quarter, pretax margin was 75% both as reported and as adjusted.
- Total equity of $22.3 billion.

The Interactive Brokers Group, Inc. Board of Directors declared a quarterly cash dividend of $0.0875 per share. This dividend is payable on September 14, 2026, to shareholders of record as of September 1, 2026.

Other Items

Other income increased 88% to $79 million. This increase is comprised mainly of $26 million from our currency diversification strategy and $11 million from our investing activities.

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 $36 million, as the U.S. dollar value of the GLOBAL decreased by approximately 0.21%. The effects of the currency diversification strategy are reported as components of (1) Other Income (gain of $21 million) and (2) Other Comprehensive Income (loss of $57 million).

¹ Represents the average amount of customer cash swept into FDIC-insured banks as part of our Insured Bank Deposit Sweep Program. 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 Net interest income on "Segregated cash and securities, net" for the three and six months ended June 30, 2025, excludes approximately $26 million of interest income, recorded in the consolidated statements of comprehensive income, related to taxes withheld at source in prior periods which was determined to be fully refundable.

³ We estimate that if the interest earned and paid on cash collateral related to our securities lending transactions were included under “Securities borrowed and loaned, net” in the table above, the total net interest income related to our securities lending activities would have been $343 million and $612 million for the three and six months ended June 30, 2026, respectively, compared to $251 million and $437 million for the three and six months ended June 30, 2025, respectively. Such additional interest attributed to our securities lending activities would be reclassified from net interest income on “Segregated cash and securities, net” and “Customer credit balances, net” in the table above, so it would have no effect on our overall net interest income or net interest margin.

⁴ 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).

⁵ 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 three and six months ended June 30, 2026 and 2025, $11 million, $22 million, $9 million, and $17 million were reported in "Other fees and services", respectively. For the three and six months ended June 30, 2026 and 2025, $32 million, $70 million, $18 million, and $34 million were reported in "Other income", respectively.

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 Amounts may not add due to rounding.
