RAISES QUARTERLY DIVIDEND FROM $0.0875 TO $0.15

Interactive Brokers Group, Inc. (NASDAQ:IBKR), an automated global broker, announced results for the quarter ended September 30, 2026.

Reported diluted earnings per share were $0.69 for the current quarter and $0.67 as adjusted. For the year-ago quarter, reported diluted earnings per share were $0.59 and $0.57 as adjusted.

Reported net revenues were $1.91 billion for the current quarter and $1.87 billion as adjusted. For the year-ago quarter, reported net revenues were $1.66 billion and $1.61 billion as adjusted.

Reported income before income taxes was $1.50 billion for the current quarter and $1.45 billion as adjusted. For the year-ago quarter, reported income before income taxes were $1.31 billion and $1.27 billion as adjusted.

Financial Highlights

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

Commission revenue increased 12% to $602 million on 18% higher DARTs² and higher regulatory fees, which are passed through to customers. Customer trading volume in futures increased 13%, while stocks and options volumes decreased 24% and 1%, respectively.

Net interest income increased 19% to $1.15 billion, primarily on higher average customer margin loans and customer credit balances.

Other fees and services increased 33% to $88 million, led by increases of $11 million in risk exposure fees, $3 million in payments for order flow from exchange-mandated programs, and $3 million in market data fees.

Execution, clearing and distribution fees increased 46% to $134 million, mainly driven by a $30 million increase in regulatory fees due to a higher SEC Section 31 transaction fee rate.

Pretax profit margin for the current quarter was 78% both as reported and as adjusted. For the year-ago quarter, pretax margin was 79% both as reported and as adjusted.

Total equity of $23.3 billion.

The Interactive Brokers Group, Inc. Board of Directors declared an increase in the quarterly cash dividend from $0.0875 per share to $0.15 per share. This dividend is payable on December 14, 2026, to shareholders of record as of December 1, 2026.

Business Highlights

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

Customer accounts increased 35% to 5.58 million.
Customer equity increased 27% to $964.7 billion.
Total DARTs increased 18% to 4.27 million.
Customer credits increased 20% to $186.2 billion.
Customer margin loans increased 36% to $105.2 billion.

Other Items

Other income decreased 18% to $70 million. This decrease is comprised mainly of $50 million from our investing activities; partially offset by an increase of $36 million from our currency diversification strategy.

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 $4 million, as the U.S. dollar value of the GLOBAL decreased by approximately 0.08%. The effects of the currency diversification strategy are reported as components of (1) Other Income (gain of $40 million) and (2) Other Comprehensive Income (loss of $44 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 nine months ended September 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 $427 million and $1,039 million for the three and nine months ended September 30, 2026, respectively, compared to $314 million and $751 million for the three and nine months ended September 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 nine months ended September 30, 2026 and 2025, $11 million, $33 million, $10 million, and $27 million were reported in "Other fees and services", respectively. For the three and nine months ended September 30, 2026 and 2025, $26 million, $96 million, $22 million, and $56 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.

¹Adjusted 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.

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

⁴Amounts may not add due to rounding.
