— — —
GAAP DILUTED EPS OF $0.63, ADJUSTED1 EPS OF $0.65
GAAP NET REVENUES OF $1.64 BILLION, ADJUSTED NET REVENUES OF $1.67 BILLION
GREENWICH, CT, January 20, 2026 — Interactive Brokers Group, Inc. (Nasdaq: IBKR), an automated global electronic broker, announced results for the quarter ended December 31, 2025.
Reported diluted earnings per share were $0.63 for the current quarter and $0.65 as adjusted. For the year-ago quarter, reported diluted earnings per share2 were $0.50 and $0.51 as adjusted.
Reported net revenues were $1.64 billion for the current quarter and $1.67 billion as adjusted. For the year-ago quarter, reported net revenues were $1.39 billion and $1.42 billion as adjusted.
Reported income before income taxes was $1.30 billion for the current quarter and $1.33 billion as adjusted. For the year-ago quarter, reported income before income taxes was $1.04 billion and $1.08 billion as adjusted.
Financial Highlights
(All comparisons are to the year-ago quarter.)
Commission revenue increased 22% to $582 million on higher customer trading volumes. Customer trading volume in options, futures and stocks increased 27%, 22% and 16%, respectively.
Net interest income increased 20% to $966 million on higher average customer margin loans and customer credit balances and stronger securities lending activity.
Other fees and services increased 5% to $85 million, led by increases of $5 million in payments for order flow from exchange-mandated programs, $2 million in FDIC sweep fees and $2 million in market data fees, partially offset by a decrease of $9 million in risk exposure fees.
Execution, clearing and distribution fees decreased 21% to $91 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.
Pretax profit margin for the current quarter was 79% both as reported and as adjusted. For the year-ago quarter, pretax margin was 75% as reported and 76% as adjusted.
Total equity of $20.5 billion.
The Interactive Brokers Group, Inc. Board of Directors declared a quarterly cash dividend of $0.08 per share. This dividend is payable on March 13, 2026, to shareholders of record as of February 27, 2026.
1 See the reconciliation of non-GAAP financial measures starting on page 10.
2 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.
Business Highlights
(All comparisons are to the year-ago quarter.)

In this quarter, our currency diversification strategy decreased our comprehensive earnings by $7 million, as the U.S. dollar value of the GLOBAL decreased by approximately 0.07%. The effects of the currency diversification strategy are reported as components of (1) Other Income (loss of $23 million) and (2) Other Comprehensive Income (gain of $16 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 twelve months ended December 31, 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 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).
4 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 twelve months ended December 31, 2025 and 2024, $11 million, $38 million, $8 million, and $28 million were reported in other fees and services, respectively. For the three and twelve months ended December 31, 2025 and 2024, $30 million, $86 million, $15 million, and $47 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 Remeasurement of our TRA liability represents the change in the amount payable to IBG Holdings LLC under the TRA, primarily due to changes in the Company’s effective tax rates. This is related to the remeasurement of the deferred tax assets described below. For further information refer to Note 4 – Equity and Earnings per Share under Part II, Item 8 – Financial Statements and Supplementary Data of the Company’s Annual Report on Form 10-K filed with the Securities Exchange Commission (“SEC”) on February 27, 2025.
4 The income tax effect is estimated using the statutory income tax rates applicable to the Company.
5 Remeasurement of certain deferred tax assets represents the change in the unamortized balance of deferred tax assets related to the step-up in basis arising from the acquisition of interests in IBG LLC, primarily due to changes in the Company’s effective tax rates. For further information refer to Note 4 – Equity and Earnings per Share under Part II, Item 8 – Financial Statements and Supplementary Data of the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2025.
6 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.
7Amounts may not add due to rounding.
