As a result of a federal income tax election made by IBG LLC applicable to the acquisition of IBG LLC member interests by IBG, Inc., the income tax basis of the assets of IBG LLC acquired by IBG, Inc. have been adjusted based on the amount paid for such interests. Deferred tax assets were recorded as of the IPO date and in connection with subsequent redemptions of Holdings member interests in exchange for common stock. These deferred tax assets are included in “Other assets” in the Company’s condensed consolidated statements of financial condition and are being amortized as additional deferred income tax expense over 15 years from the IPO date and from the additional redemption dates, respectively, as allowable under current tax law. As of September 30, 2025 and December 31, 2024, the unamortized balance of these deferred tax assets was $223 million and $196 million, respectively. IBG, Inc. also entered into an agreement (the “Tax Receivable Agreement”) with Holdings to pay Holdings (for the benefit of the former members of IBG LLC) 85% of the tax savings that IBG, Inc. actually realizes as the result of tax basis increases. These payables to Holdings are reported as “Payable to affiliate” in the Company’s condensed consolidated statements of financial condition. The remaining 15% is accounted for as a permanent increase to “Additional paid-in capital” in the Company’s condensed consolidated statements of financial condition. The cumulative amounts of deferred tax assets, payables to Holdings and additional paid-in capital arising from stock offerings from the date of the IPO through September 30, 2025 were $727 million, $618 million and $109 million, respectively. Amounts payable under the Tax Receivable Agreement are payable to Holdings annually following the filing of IBG, Inc.’s federal income tax return. The Company has paid Holdings a cumulative total of $308 million through September 30, 2025 under the terms of the Tax Receivable Agreement. The Exchange Agreement, as amended, provides for future redemptions of member interests and for the purchase of member interests in IBG LLC by IBG, Inc. from Holdings, which could result in IBG, Inc. acquiring the remaining member interests in IBG LLC that it does not own. On an annual basis, members of Holdings can request redemption of their interests. At the time of IBG, Inc.’s IPO in 2007, the Company reserved 360 million shares, 1.440 billion shares on a post-split basis, of authorized common stock for future sales and redemptions. From 2008 through 2010, Holdings redeemed 20,053,036 IBG LLC interests with a total value of $114 million, which redemptions were funded using cash on hand at IBG LLC. Upon cash redemption, these IBG LLC interests were retired. From 2011 through 2024, IBG, Inc. issued 161,777,780 shares of common stock (with a fair value of $2.0 billion) directly to Holdings in exchange for an equivalent number of member interests in IBG LLC. On July 30, 2025, the Company filed a Prospectus Supplement on Form 424B5 with the SEC to issue 3,836,000 shares of common stock (with a fair value of $254 million) in exchange for an equivalent number of shares of member interest in IBG LLC. On July 26, 2023, the Company filed a Prospectus Supplement on Form 424B (File Number 333-273451) with the SEC to re-register up to 2,520,000 shares of common stock, offering the opportunity for eligible persons to receive awards in the form of an offer to receive such shares by participating in one or more promotions that are designed to attract new customers to the Company’s brokerage platform, increase assets held with the Company’s brokerage business and enhance customer loyalty. The Company has authorized a total of 4,000,000 shares of common stock to be issued under these promotions. From 2019 through September 30, 2025, the Company issued 2,880,000 shares to IBG LLC for distribution to eligible customers of certain of its subsidiaries. As a consequence of redemption transactions in accordance with the Exchange Agreement, distribution of shares to customers under one or more promotions, and distribution of shares to employees (see Note 10), IBG, Inc.’s interest in IBG LLC has increased to approximately 26.3%, with Holdings owning the remaining 73.7% as of September 30, 2025. The redemptions also increased the Holdings interest held by Mr. Thomas Peterffy and his affiliates from approximately 84.6% at the IPO to approximately 91.6% as of September 30, 2025.
