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, our net mark-to-market<br> gains (losses) on investments^2^, and the remeasurement of our Tax Receivable Agreement (“TRA”) liability^3^.
We define adjusted income before income taxes as income before income taxes adjusted to remove the effect of our currency diversification strategy,<br> our net mark-to-market gains (losses) on investments, the remeasurement of our TRA liability, and unusual bad debt expense^4^.
--- ---
We define adjusted net income available to common stockholders as net income available for common stockholders adjusted to remove the after-tax<br> effects attributable to IBG, Inc. of our currency diversification strategy our net mark-to-market gains (losses) on investments, the remeasurement of our TRA liability, unusual bad debt expense, and the remeasurement of certain deferred tax<br> assets^6^.
--- ---
We define adjusted diluted EPS as adjusted net income available for common stockholders divided by the diluted weighted average number of shares<br> 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 portfolio, which are typically held to maturity, and on certain other investments, including equity securities taken over by the Company from customers related to losses on margin loans.

^3^Remeasurement of our tax receivable agreement (“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 24, 2023.

^4^Unusual bad debt expense consists of a credit loss on a loan not related to margin lending.

^5^The income tax effect is estimated using the statutory income tax rates applicable to the Company.

^6^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 Securities Exchange Commission (“SEC”) on February 24, 2023.
