REPORTS COMPREHENSIVE EARNINGS PER SHARE OF $0.41,

INCOME BEFORE TAXES OF $204 MILLION ON $387 MILLION IN NET REVENUES,

AND EARNINGS PER SHARE ON NET INCOME OF $0.32.

DECLARES QUARTERLY DIVIDEND OF $0.10 PER SHARE.

GREENWICH, CONN, July 18, 2017 — Interactive Brokers Group, Inc. (NASDAQ GS: IBKR) an automated global electronic broker and market maker, today reported diluted earnings per share on a comprehensive basis of $0.41 for the quarter ended June 30, 2017, compared to diluted earnings per share on a comprehensive basis of $0.36 for the same period in 2016.

Net revenues were $387 million and income before income taxes was $204 million this quarter, compared to net revenues of $369 million and income before income taxes of $213 million for the same period in 2016.

The results for the quarter were positively impacted by strong growth in net interest income, which increased $29 million, or 23%, and higher commissions, which increased $8 million, or 5% from the year-ago quarter. Trading gains decreased 62% from the year-ago quarter on lower market making trading volumes, as we wind down our options market making business, and decreases in volatility and in the actual-to-implied volatility ratio.

In addition, the results for the quarter include a $66 million gain on our currency diversification strategy, compared to a $2 million loss in the same period in 2016; a $3 million net mark-to-market loss on our U.S. government securities portfolio compared to a $14 million net mark-to-market gain in the same period in 2016; and approximately $22 million in one-time exit costs related to the wind-down of our options market making business, primarily consisting of the write-down of exchange trading rights.

The Interactive Brokers Group, Inc. Board of Directors declared a quarterly cash dividend of $0.10 per share. This dividend is payable on September 14, 2017 to shareholders of record as of September 1, 2017.

Segment Overview

Electronic Brokerage

Electronic brokerage segment income before income taxes increased 4%, to $198 million in the quarter ended June 30, 2017, compared to the same period last year. Net revenues increased 8% to $334 million on higher net interest income and commissions revenue, partially offset by a net mark-to-market loss on our U.S. government securities portfolio.

Net interest income increased 25% as average customer credit and margin balances and benchmark interest rates increased from the year-ago quarter. Commissions revenue increased 5% from the year-ago quarter on higher customer volumes in options and stocks, which increased 12% and 55%, respectively, from the year-ago quarter. Other income decreased 33% over the year-ago quarter, driven by a non-recurrence of net mark-to-market gains on investments in U.S. government securities in the year-ago quarter. Pretax profit margin was 59% for the quarter ended June 30, 2017, down from 62% in the same period last year.

Customer accounts grew 20% to 428 thousand and customer equity increased 42% from the year-ago quarter to $104.8 billion. Total DARTs1 for cleared and execution-only customers increased 3% to 669 thousand from the year-ago quarter. Cleared DARTs were 621 thousand, 4% higher than in the same period last year.

Market Making

Market making segment income before income taxes decreased to a loss of $24 million in the quarter ended June 30, 2017, due to lower trading volumes, as we wind down our options market making business, and decreases in volatility and in the actual-to-implied volatility ratio. In addition, the results for the quarter include approximately $22 million in one-time exit costs, primarily consisting of the write-down of exchange trading rights, in line with previously disclosed estimates.

Effects of Foreign Currency Diversification

In connection with our currency diversification strategy, we have determined to base our net worth in GLOBALs, a basket of 14 major currencies in which we hold our equity. In this quarter, our currency diversification strategy increased our comprehensive earnings by $66 million, as the U.S. dollar value of the GLOBAL increased by approximately 1.06%. The effects of the currency diversification strategy are reported as components of (1) Other Income in the corporate segment and (2) Other Comprehensive Income (“OCI”).
