**2. Significant Accounting Policies**

***Basis of Presentation*** 

These condensed consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP") and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") regarding financial reporting with respect to Form 10-Q.

These condensed consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's 2025 Annual Report on Form 10-K for the year ended December 31, 2025, which was filed with the SEC on February 27, 2026. The condensed consolidated financial information as of December 31, 2025 has been derived from the audited financial statements not included herein.

These condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries and reflect all adjustments of a normal and recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the periods presented. The operating results for interim periods are not necessarily indicative of the operating results for the entire year.

On April 15, 2025, the Company announced its intention to effect a four-for-one forward split of its common stock in the form of a stock dividend. This was executed by the filing of an amendment to the Company's Certificate of Incorporation, which was approved by the Company's Board of Directors and the Company's majority stockholder on April 14, 2025 and on April 22, 2025, respectively, that, among other things (i) increased the Company's authorized shares of Class A common stock to 4,000,000,000 shares from 1,000,000,000 shares and (ii) increased the Company's authorized shares of Class B Common Stock to 1,000 shares from 100 shares to accommodate the stock split. Each holder of record of common stock as of the close of market on June 16, 2025, received three additional shares of common stock. All prior period shares, per share amounts and stock incentive awards presented herein have been retroactively adjusted to reflect the stock split.

***Principles of Consolidation, including Noncontrolling Interests***

These condensed consolidated financial statements include the accounts of IBG, Inc. and its majority and wholly-owned subsidiaries. As sole managing member of IBG LLC, IBG, Inc. exerts control over IBG LLC's operations. In accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 810, "Consolidation," the Company consolidates IBG LLC's financial statements and records the interests in IBG LLC that it does not own as noncontrolling interests.

**Interactive Brokers Group, Inc. and Subsidiaries**

**Notes to Unaudited Condensed Consolidated Financial Statements**

The Company's policy is to consolidate all other entities in which it owns more than 50% unless it does not have control and any potential variable interest entities ("VIEs") where the Company is deemed to be the primary beneficiary when it has the power to make the decisions that most significantly affect the economic performance of the VIE and has the obligation to absorb significant losses or the right to receive benefits that could potentially be significant to the VIE. As of March 31, 2026, the Company was not the primary beneficiary of any VIEs. All inter-company balances and transactions have been eliminated.

***Use of Estimates***

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in these condensed consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. Such estimates include the allowance for credit losses, valuation of certain investments, compensation accruals, current and deferred income taxes, and contingency reserves.

***Fair Value***

Substantially all of the Company's assets and liabilities, including financial instruments, are carried at fair value based on observable market prices and are marked to market, or are assets and liabilities which are short-term in nature and are carried at amounts that approximate fair value.

The Company applies the fair value hierarchy in accordance with FASB ASC Topic 820, "Fair Value Measurement" ("ASC Topic 820"), to prioritize the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy are:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;Level 1 | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. |
| &nbsp;&nbsp;&nbsp;Level 2 | Quoted prices for similar assets in an active market, quoted prices in markets that are not considered to be active or financial instruments for which all significant inputs are observable, either directly or indirectly. |
| &nbsp;&nbsp;&nbsp;Level 3 | Prices or valuations that require inputs that are both significant to fair value measurement and unobservable. |

---

Financial instruments owned, at fair value, and financial instruments sold, but not yet purchased, at fair value are generally classified as Level 1 of the fair value hierarchy. The Company's Level 1 financial instruments, which are valued using quoted market prices as published by exchanges and clearing houses or otherwise broadly distributed in active markets, include active listed stocks, options, warrants and U.S. and foreign government securities. The Company does not adjust quoted prices for financial instruments classified as Level 1 of the fair value hierarchy, even if the Company may hold a large position whereby a purchase or sale could reasonably be expected to impact quoted prices.

Currency forward contracts are valued using broadly distributed bank and broker prices and are classified as Level 2 of the fair value hierarchy since inputs to their valuation can generally be corroborated by market data. Precious metals are valued using an internal model, which incorporates the exchange-traded futures price of the underlying instruments, benchmark interest rates and estimated storage costs, and are classified as Level 2 of the fair value hierarchy since the significant inputs to their valuation are observable. Other securities that are not traded in active markets are also classified as Level 2 of the fair value hierarchy. Level 3 financial instruments are comprised of securities that have been delisted or otherwise are no longer tradable in active markets and have been valued by the Company based on internal estimates.

***Earnings per Share***

Earnings per share ("EPS") is computed in accordance with FASB ASC Topic 260, "Earnings per Share." Basic EPS is computed by dividing the net income available for common stockholders by the weighted average number of shares outstanding for that period. Diluted EPS is calculated by dividing the net income available for common stockholders by the diluted weighted average shares outstanding for that period. Diluted EPS includes the determinants of basic EPS and, in addition, reflects the dilutive effect of shares of common stock estimated to be distributed in the future under the Company's stock-based compensation plans, with no adjustments to net income available for common stockholders for potentially dilutive common shares.

**Notes to Unaudited Condensed Consolidated Financial Statements**

***Current Expected Credit Losses***

The Company follows FASB ASC Topic 326 – "Financial Instruments – Credit Losses" ("ASC Topic 326") which applies to financial assets measured at amortized cost, held-to-maturity debt securities and off-balance sheet credit exposures. For on-balance sheet assets, an allowance must be recognized at the origination or purchase of in-scope assets and represents the expected credit losses over the contractual life of those assets. Expected credit losses on off-balance sheet credit exposures must be estimated over the contractual period the Company is exposed to credit risk as a result of a present obligation to extend credit. The impact to the current period is not material since the Company's in-scope assets are primarily subject to collateral maintenance provisions for which the Company elected to apply the practical expedient of reporting the difference between the fair value of the collateral and the amortized cost for the in-scope assets as the allowance for current expected credit losses.

***Cash and Cash Equivalents***

Cash and cash equivalents consist of deposits with banks and all highly liquid investments, with maturities of three months or less, that are not segregated and deposited for regulatory purposes or to meet margin requirements at clearing houses and clearing banks.

***Cash and Securities – Segregated for Regulatory Purposes***

As a result of customer activities, certain operating subsidiaries are obligated by rules mandated by their primary regulators to segregate or set aside cash or qualified securities to satisfy such regulations, which have been promulgated to protect customer assets. Restricted cash represents cash and cash equivalents that are subject to withdrawal or usage restrictions. Cash segregated for regulatory purposes meets the definition of restricted cash and is reported in "Cash, cash equivalents and restricted cash" in the condensed consolidated statements of cash flows.

The table below presents the composition of the Company's securities segregated for regulatory purposes for the periods indicated.

|  | $41889 | $26521 |

---

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.These balances are collateralized by U.S. government securities.

***Securities Borrowed and Securities Loaned***

Securities borrowed and securities loaned are recorded at the amount of the cash collateral advanced or received. Securities borrowed transactions require the Company to provide counterparties with collateral, which may be in the form of cash, letters of credit or other securities. With respect to securities loaned, the Company receives collateral, which may be in the form of cash or other securities in an amount generally in excess of the fair value of the securities loaned. The Company monitors the market value of securities borrowed and loaned daily, with additional collateral obtained or refunded as permitted contractually. The Company's policy is to net, in the condensed consolidated statements of financial condition, securities borrowed and securities loaned contracts entered into with the same counterparty that meet the offsetting requirements prescribed in FASB ASC Topic 210-20, "Balance Sheet – Offsetting" ("ASC Topic 210-20").

Securities lending fees received and paid by the Company are reported in "Interest income" and "Interest expense," respectively, in the condensed consolidated statements of comprehensive income.

**Notes to Unaudited Condensed Consolidated Financial Statements**

***Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase***

Securities purchased under agreements to resell and securities sold under agreements to repurchase, which are reported as collateralized financing transactions, are recorded at contract value, which approximates fair value. To ensure that the fair value of the underlying collateral remains sufficient, the collateral is valued daily with additional collateral obtained or excess collateral returned, as permitted under contractual provisions. The Company's policy is to net, in the condensed consolidated statements of financial condition, securities purchased under agreements to resell transactions and securities sold under agreements to repurchase transactions entered into with the same counterparty that meet the offsetting requirements prescribed in ASC Topic 210-20.

***Financial Instruments Owned and Financial Instruments Sold, But Not Yet Purchased, at Fair Value***

Financial instrument transactions are accounted for on a trade date basis. Financial instruments owned and financial instruments sold, but not yet purchased are stated at fair value based upon quoted market prices, or if not available, are valued by the Company based on internal estimates (see Fair Value above). The Company's financial instruments pledged to counterparties where the counterparty has the right, by contract or custom, to sell or repledge the financial instruments are reported in "Financial instruments owned and pledged as collateral" in the condensed consolidated statements of financial condition.

***Customer Receivables and Payables***

Receivables from and payables to customers include amounts due on cash and margin transactions, including futures contracts transacted on behalf of customers. Securities owned by customers, including those that collateralize margin loans or other similar transactions, are not reported in the condensed consolidated statements of financial condition. Amounts receivable from customers that are determined by management to be uncollectible are reported in "Customer bad debt" in the condensed consolidated statements of comprehensive income (see Current Expected Credit Losses above).

***Receivables from and Payables to Brokers, Dealers and Clearing Organizations***

Receivables from and payables to brokers, dealers and clearing organizations include net receivables and payables from unsettled trades, including amounts related to futures and options on futures contracts executed on behalf of customers, amounts receivable for securities not delivered by the Company to the purchaser by the settlement date ("fails to deliver") and cash deposits. Payables to brokers, dealers and clearing organizations also include amounts payable for securities not received by the Company from a seller by the settlement date ("fails to receive").

***Investments***

The Company makes certain strategic investments related to its business which are reported in "Other assets" in the condensed consolidated statements of financial condition. The Company accounts for these investments as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Under the equity method of accounting as required under FASB ASC Topic 323, "Investments – Equity Method and Joint Ventures." These investments, including where the investee is a limited partnership or limited liability company, are recorded at the fair value amount of the Company's initial investment and are adjusted each period for the Company's share of the investee's income or loss. Contributions paid to and distributions received from equity method investees are recorded as additions or reductions, respectively, to the respective investment balance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•At fair value, if the investment in equity securities has a readily determinable fair value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•At adjusted cost, if the investment does not have a readily determinable fair value. Adjusted cost represents the historical cost, less impairment if any. If the Company identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, the Company measures the equity security at fair value as of the date that the observable transaction occurred in accordance with FASB ASC Topic 321, "Investments in Equity Securities."

A judgmental aspect of accounting for investments is evaluating whether a decline in the value of an investment has occurred. The evaluation of impairment is dependent on specific quantitative and qualitative factors and circumstances surrounding an investment, including recurring operating losses, credit defaults and subsequent rounds of financing. Most of the Company's equity investments do not have readily determinable market values. All investments are reviewed for changes in circumstances or occurrence of events that suggest the Company's investment may not be recoverable. An impairment loss, if any, is recognized in the period the determination is made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The Company's share of income or losses is reported in "Other income" in the condensed consolidated statements of comprehensive income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.These investments do not qualify for the equity method of accounting. Dividends received are reported in "Other income" in the condensed consolidated statements of comprehensive income.

***Property, Equipment and Intangible Assets***

Property, equipment and intangible assets, which are reported in "Other assets" in the condensed consolidated statements of financial condition, consist of leasehold improvements, computer equipment, software developed for the Company's internal use, office furniture and equipment.

Property and equipment are recorded at historical cost, less accumulated depreciation and amortization. Additions and improvements that extend the lives of assets are capitalized, while expenditures for repairs and maintenance are expensed as incurred. Depreciation and amortization are computed using the straight-line method. Equipment is depreciated over the estimated useful lives of the assets, while leasehold improvements are amortized over the lesser of the estimated economic useful life of the asset or the term of the lease. Computer equipment is depreciated over three to five years and office furniture and equipment are depreciated over five to seven years. Intangible assets with a finite life are amortized on a straight-line basis over their estimated useful lives of three to five years, and tested for recoverability whenever events indicate that the carrying amounts may not be recoverable. Qualifying costs for internally developed software are capitalized and amortized over the expected useful life of the developed software, not to exceed three years. Upon retirement or disposition of property and equipment, the cost and related accumulated depreciation are removed from the condensed consolidated statements of financial condition and any resulting gain or loss is reported in "Other income" in the condensed consolidated statements of comprehensive income. Fully depreciated (or amortized) assets are retired periodically throughout the year.

***Leases***

The Company reviews all relevant contracts to determine if the contract contains a lease at its inception date. A contract contains a lease if the contract conveys to the company the right to control the use of an underlying asset for a period of time in exchange for consideration. If the Company determines that a contract contains a lease, it recognizes, in the condensed consolidated statements of financial condition, a lease liability and a corresponding right-of-use asset on the commencement date of the lease. The lease liability is initially measured at the present value of the future lease payments over the lease term using the rate implicit in the lease or, if not readily determinable, the Company's secured incremental borrowing rate. An operating lease right-of-use asset is initially measured at the value of the lease liability minus any lease incentives and initial direct costs incurred plus any prepaid rent.

The Company's leases are classified as operating leases and consist of real estate leases for office space, data centers and other facilities. Each lease liability is measured using the Company's secured incremental borrowing rate, which is based on an internally developed yield curve using interest rates of third parties' corporate debt issued with a similar risk profile as the Company and a duration similar to the lease term. The Company's leases have remaining terms of less than one year to thirteen years, some of which include options to extend the lease term, and some of which include options to terminate the lease upon notice. The Company considers these options when determining the lease term used to calculate the right-of-use asset and the lease liability when the Company is reasonably certain it will exercise such option.

------

[**<u>**Table of Contents**</u>**](#toc_page)

**Interactive Brokers Group, Inc. and Subsidiaries**

**Notes to Unaudited Condensed Consolidated Financial Statements**

The Company's operating leases contain both lease components and non-lease components. Non-lease components are distinct elements of a contract that are not related to securing the use of the underlying assets, such as common area maintenance and other management costs. The Company elected to measure the lease liability by combining the lease and non-lease components as a single lease component. As such, the Company includes the fixed payments and any payments that depend on a rate or index that relate to the lease and non-lease components in the measurement of the lease liability. Some of the non-lease components are variable and not based on an index or rate, and as a result, are not included in the measurement of the right-of-use asset or lease liability.

Operating lease expense is recognized on a straight-line basis over the lease term and is reported in "Occupancy, depreciation and amortization" in the condensed consolidated statements of comprehensive income.

***Comprehensive Income and Foreign Currency Translation***

The Company's operating results are reported in the condensed consolidated statements of comprehensive income pursuant to FASB ASC Topic 220, "Comprehensive Income."

Comprehensive income consists of two components: net income and other comprehensive income ("OCI"). The Company's OCI is comprised of gains and losses resulting from translating foreign currency financial statements of non-U.S. subsidiaries, net of related income taxes, where applicable. In general, the practice and intention of the Company is to reinvest the earnings of its non-U.S. subsidiaries in those operations; therefore, tax is usually not accrued on OCI.

The Company's non-U.S. domiciled subsidiaries have a functional currency that is other than the U.S. dollar. Such subsidiaries' assets and liabilities are translated into U.S. dollars at period-end exchange rates, and revenues and expenses are translated at average exchange rates prevailing during the period. Adjustments that result from translating amounts from a subsidiary's functional currency to the U.S. dollar (as described above) are reported net of tax, where applicable, in "Accumulated other comprehensive income" in the condensed consolidated statements of financial condition.

***Revenue Recognition***

*Commissions* 

Commissions earned for executing and/or clearing transactions are accrued on a trade date basis and are reported in "Commissions" in the condensed consolidated statements of comprehensive income. Commissions also include payments for order flow income received from IBKR Lite<sup>SM</sup> liquidity providers. The Company's IBKR Lite<sup>SM</sup> offering provides commission-free trades on U.S. exchange-listed stocks and ETFs and generates no commission revenues from customers on these trades. See Note 8 for further information on revenue from contracts with customers.

*Other Fees and Services*

The Company earns fee income on services provided to customers, which includes market data fees, risk exposure fees, payments for order flow from exchange-mandated programs, Insured Bank Deposit Sweep Program fees ("FDIC sweep fees"), and other fees and services charged to customers, which are reported in "Other fees and services" in the condensed consolidated statements of comprehensive income. Fee income is recognized either daily or monthly. See Note 8 for further information on revenue from contracts with customers.

*Interest Income and Expense*

The Company earns interest income and incurs interest expense primarily in connection with its brokerage customer business and its securities lending activities, which are recorded on an accrual basis and are reported in "Interest income" and "Interest expense," respectively, in the condensed consolidated statements of comprehensive income.

*Principal Transactions* 

Principal transactions include gains and losses as a result of changes in the fair value of financial instruments owned, at fair value, financial instruments sold, but not yet purchased, at fair value, and other investments measured at fair value (i.e., unrealized gains and losses) and realized gains and losses related to the Company's principal transactions. These include net gains and losses on stocks, options, U.S. and foreign government securities, municipal securities, futures, foreign exchange, precious metals and other derivative instruments, which are reported on a net basis in "Other income" in the condensed consolidated statements of comprehensive income. Dividends are integral to the valuation of stocks. Accordingly, dividend income and expense attributable to financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value, are reported on a net basis in "Other income" in the condensed consolidated statements of comprehensive income.

**Notes to Unaudited Condensed Consolidated Financial Statements**

*Foreign Currency Gains and Losses*

Foreign currency balances are assets and liabilities in currencies other than the Company's functional currency. At every reporting date, the Company revalues its foreign currency balances to its functional currency at the spot exchange rate and records the associated foreign currency gains and losses. These foreign currency gains and losses are reported in the condensed consolidated statements of comprehensive income, as follows: (a) foreign currency gains and losses related to the Company's currency diversification strategy are reported in "Other income"; (b) foreign currency gains and losses arising from currency swap transactions are reported in "Interest income" or "Interest expense"; and (c) all other foreign currency gains and losses are reported in "Other income."

***Rebates***

Rebates consist of volume discounts, credits, or payments received from exchanges or other market centers related to the placement and/or removal of liquidity from the marketplace and are recorded on an accrual basis. Rebates are reported net within "Execution, clearing and distribution fees" in the condensed consolidated statements of comprehensive income. Rebates received for trades executed on behalf of customers that elect tiered pricing are passed, in whole or part, to these customers, and such pass-through amounts are reported net within "Commissions" in the condensed consolidated statements of comprehensive income.

***Stock-Based Compensation*** 

The Company follows FASB ASC Topic 718, "Compensation - Stock Compensation" ("ASC Topic 718"), to account for its stock-based compensation plans. ASC Topic 718 requires all share-based payments to employees to be recognized in the condensed consolidated financial statements using a fair value-based method. Grants, which are denominated in U.S. dollars, are communicated to employees in the year of the grant, thereby establishing the fair value of each grant. The fair value of awards granted to employees are generally expensed as follows: 50% in the year of grant in recognition of the plans' post-employment provisions (as described below) and the remaining 50% over the related vesting period utilizing the "graded vesting" method permitted under ASC Topic 718. In the case of "retirement eligible" employees (those employees older than 59), 100% of awards are expensed when granted.

Awards granted under stock-based compensation plans are subject to the plans' post-employment provisions in the event an employee ceases employment with the Company. The plans provide that employees who discontinue employment with the Company without cause and continue to meet the terms of the plans' post-employment provisions will be eligible to earn 50% of previously granted but not yet earned awards, unless the employee is over the age of 59, in which case the employee would be eligible to receive 100% of previously granted but not yet earned awards.

***Income Taxes***

The Company accounts for income taxes in accordance with FASB ASC Topic 740, "Income Taxes" ("ASC Topic 740")*.* The Company's income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws (see Note 11) and reflect management's best assessment of estimated future taxes to be paid. The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgment and estimates.

Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statement recognition of underlying assets and liabilities. In evaluating the ability to recover deferred tax assets within the jurisdictions from which they arise, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates the Company is using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested.

[**<u>**Table of Contents**</u>**](#toc_page)

**Interactive Brokers Group, Inc. and Subsidiaries**

**Notes to Unaudited Condensed Consolidated Financial Statements**

The calculation of the Company's tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company's global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. A number of jurisdictions outside of the United States, including the European Union countries, have enacted legislation for global minimum taxation that was established by the Organization for Economic Cooperation and Development ("OECD") as part of the base erosion and profit shifting project known as "Pillar Two," which generally imposes a minimum effective tax rate of 15% in each of the participating jurisdictions. The Pillar Two legislation is highly complex and continues to undergo significant changes, and we continue to monitor any newly issued OECD guidance and legislation enacted by individual jurisdictions and evaluate the potential impact on income tax expense as the Pillar Two legislation becomes effective in countries where the Company operates.

The Company records tax liabilities in accordance with ASC Topic 740 and adjusts these liabilities when management's judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available.

The Company recognizes a tax benefit from an uncertain tax position only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of its technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement.

The Company recognizes interest related to income tax matters as interest income or interest expense and penalties related to income tax matters as "Income tax expense" in the condensed consolidated statements of comprehensive income.

**3. Trading Activities and Related Risks**

Trading activities expose the Company to market and credit risks. These risks are managed in accordance with established risk management policies and procedures. To accomplish this, management has established a risk management process that includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a regular review of the risk management process by executive management as part of its oversight role;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•defined risk management policies and procedures supported by a rigorous analytic framework; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•articulated risk tolerance levels as defined by executive management that are regularly reviewed to ensure that the Company's risk-taking is consistent with its business strategy, its capital structure, and current and anticipated market conditions.

***Market Risk***

The Company is exposed to various market risks. Exposures to market risks arise from equity price risk, foreign currency exchange rate fluctuations and changes in interest rates. The Company seeks to mitigate market risk associated with trading inventories by employing hedging strategies that correlate rate, price and spread movements of trading inventories and related financing and hedging activities. The Company uses a combination of cash instruments and exchange-traded derivatives to hedge its market exposures. The Company does not apply hedge accounting. The following discussion describes the types of market risk faced:

*Equity Price Risk*

Equity price risk arises from the possibility that equity security prices will fluctuate, affecting the value of equity securities and other instruments that derive their value from a particular stock, a defined basket of stocks, or a stock index. The Company is subject to equity price risk primarily in financial instruments owned, at fair value and financial instruments sold, but not yet purchased, at fair value. The Company attempts to limit such risks by continuously reevaluating prices and by diversifying its portfolio across many different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security.

*Interest Rate Risk*

Interest rate risk arises from the possibility that changes in interest rates will affect the value of financial instruments. The Company is exposed to interest rate risk on cash and margin balances, positions carried in equity and fixed income securities, options, futures and on its borrowings. These risks are managed through investment policies and by entering into interest rate futures contracts.

*Currency Risk*

Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact the value of financial instruments. The Company manages this risk using spot (i.e., cash) currency transactions, currency futures contracts and currency forward contracts. The Company actively manages its currency exposure using a currency diversification strategy that is based on a defined basket of ten currencies internally referred to as the "GLOBAL." These strategies minimize the fluctuation of the Company's equity as expressed in GLOBALs, thereby diversifying its risk in alignment with these global currencies, weighted by the Company's view of their importance. As the Company's financial results are reported in U.S. dollars, the change in the value of the GLOBAL as expressed in U.S. dollars affects the Company's earnings. The impact of this currency diversification strategy in the Company's earnings is reported in "Other income" in the condensed consolidated statements of comprehensive income.

***Credit Risk***

The Company is exposed to the risk of loss if a customer, counterparty or issuer fails to perform its obligations under contractual terms ("default risk"). Both cash instruments and derivatives expose the Company to default risk. The Company has established policies and procedures for mitigating credit risk on principal transactions, including reviewing and establishing limits for credit exposure, maintaining collateral and continually assessing the creditworthiness of counterparties.

------

[**<u>**Table of Contents**</u>**](#toc_page)

**Interactive Brokers Group, Inc. and Subsidiaries**

**Notes to Unaudited Condensed Consolidated Financial Statements**

The Company's exposure to credit risk is limited as contracts entered into are settled directly at securities and commodities clearing houses or are settled through member firms and banks with substantial financial and operational resources. Over-the-counter transactions, such as securities lending and contracts for differences ("CFDs"), are marked to market daily and are conducted with counterparties that have undergone a thorough credit review. The Company seeks to control the risks associated with its customer margin activities by requiring customers to maintain collateral in compliance with regulatory and internal guidelines.

In the normal course of business, the Company executes, settles and finances various customer securities transactions. Execution of these transactions includes the purchase and sale of securities which exposes the Company to default risk arising from the potential that customers or counterparties may fail to satisfy their obligations. In these situations, the Company may be required to purchase or sell financial instruments at unfavorable market prices to satisfy obligations to customers or counterparties. Liabilities to other brokers and dealers related to unsettled transactions (i.e., securities fails to receive) are recorded at the amount for which the securities were purchased, and are paid upon receipt of the securities from other brokers or dealers. In the case of aged securities fails to receive, the Company may purchase the underlying security in the market and seek reimbursement for any losses from the counterparty.

For cash management purposes, the Company enters into short-term securities purchased under agreements to resell and securities sold under agreements to repurchase transactions ("repos") in addition to securities borrowing and lending arrangements, all of which may result in credit exposure in the event the counterparty to a transaction is unable to fulfill its contractual obligations. Repos are collateralized by securities with a market value in excess of the obligation under the contract. Similarly, securities lending agreements are collateralized by deposits of cash or securities. The Company attempts to minimize credit risk associated with these activities by monitoring collateral values daily and requiring additional collateral to be deposited with or returned to the Company as permitted under contractual provisions.

***Concentrations of Credit Risk***

The Company's exposure to credit risk associated with its trading and other activities is measured on an individual counterparty basis, as well as by groups of counterparties that share similar attributes. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, credit limits are established and exposure is monitored in light of changing counterparty and market conditions. As of March 31, 2026, the Company did not have any material concentrations of credit risk outside the ordinary course of business.

***Off-Balance Sheet Risks***

The Company may be exposed to a risk of loss not reflected in the condensed consolidated financial statements to settle futures and certain over-the-counter contracts at contracted prices, which may require repurchase or sale of the underlying products in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk as the Company's cost to liquidate such contracts may exceed the amounts reported in the condensed consolidated statements of financial condition.

**4. Equity and Earnings per Share**

In connection with IBG, Inc.'s initial public offering of Class A common stock ("IPO") in May 2007, it purchased 10.0% of the membership interests in IBG LLC from IBG Holdings LLC ("Holdings"), became the sole managing member of IBG LLC and began to consolidate IBG LLC's financial results into its financial statements. Holdings owns all of IBG, Inc.'s Class B common stock, which has voting rights in proportion to its ownership interests in IBG LLC. The table below presents the amount of IBG LLC membership interests held by IBG, Inc. and Holdings as of March 31, 2026.

***Recapitalization and Post-IPO Capital Structure***

Immediately before and immediately following the consummation of the IPO, IBG, Inc., Holdings, IBG LLC and the members of IBG LLC consummated a series of transactions collectively referred to herein as the "Recapitalization." In connection with the Recapitalization, IBG, Inc., Holdings and the historical members of IBG LLC entered into an exchange agreement, dated as of May 3, 2007 (the "Exchange Agreement"), under which the historical members of IBG LLC received membership interests in Holdings in exchange for their membership interests in IBG LLC. Additionally, IBG, Inc. became the sole managing member of IBG LLC.

In connection with the consummation of the IPO, Holdings used the net proceeds to redeem 10.0% of members' interests in Holdings in proportion to their interests. Immediately following the Recapitalization and IPO, Holdings owned approximately 90% of IBG LLC and 100% of IBG, Inc.'s Class B common stock.

Since the consummation of the IPO and Recapitalization, IBG, Inc.'s equity capital structure has been comprised of Class A and Class B common stock. All shares of common stock have a par value of $0.01 per share and have identical rights to earnings and dividends and in liquidation. The below table presents the authorized, issued, and outstanding shares for the periods indicated.

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 reported in "Other assets" in the 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 March 31, 2026 and December 31, 2025, the unamortized balance of these deferred tax assets was $217 million and $222 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 in "Payable to affiliate" in the condensed consolidated statements of financial condition. The remaining 15% is accounted for as a permanent increase to "Additional paid-in capital" in the 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 March 31, 2026 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 March 31, 2026 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 2025, IBG, Inc. issued 165,613,780 shares of common stock (with a fair value of $2.2 billion) directly to Holdings in exchange for an equivalent number of member interests 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 March 31, 2026, the Company issued 3,080,000 shares to IBG LLC for distribution to eligible customers of certain of its subsidiaries.

**7. Collateralized Transactions**

The Company enters into securities borrowing and lending transactions and agreements to repurchase and resell securities to finance trading inventory, to obtain securities for settlement and to earn residual interest rate spreads. In addition, the Company's customers pledge their securities owned to collateralize margin loans. Under these transactions, the Company either receives or provides collateral, including equity, corporate debt and U.S. government securities. Under typical agreements, the Company is permitted to sell or repledge securities received as collateral and use these securities to secure securities purchased under agreements to resell, enter into securities lending transactions or deliver these securities to counterparties to cover short positions.

The Company also engages in securities financing transactions with and for customers through margin lending. Customer receivables generated from margin lending activity are collateralized by customer-owned securities held by the Company. Customers' required margin levels and established credit limits are monitored continuously by risk management staff using automated systems. Pursuant to the Company's policy and as enforced by such systems, customers are required to deposit additional collateral or reduce positions, when necessary, to avoid automatic liquidation of their positions.

Margin loans are extended to customers on a demand basis and are not committed facilities. Factors considered in the acceptance or rejection of margin loans are the amount of the loan, the degree of leverage being employed in the customer account and an overall evaluation of the customer's portfolio to ensure proper diversification or, in the case of concentrated positions, appropriate liquidity of the underlying collateral. Additionally, transactions relating to concentrated or restricted positions are limited or prohibited by raising the level of required margin collateral (to 100% in the extreme case). The underlying collateral for margin loans is evaluated with respect to the liquidity of the collateral positions, valuation of securities, volatility analysis and an evaluation of industry concentrations. Adherence to the Company's collateral policies significantly limits the Company's credit exposure to margin loans in the event of a customer's default. Under margin lending agreements, the Company may request additional margin collateral from customers and may sell securities that have not been paid for or purchase securities sold but not delivered from customers, if necessary. As of March 31, 2026 and December 31, 2025, approximately $86.5 billion and $90.5 billion, respectively, of customer margin loans were outstanding.

The table below presents a summary of the amounts related to collateralized transactions for the periods indicated.

**8. Revenues from Contracts with Customers** 

Revenue from contracts with customers is recognized when, or as, the Company satisfies its performance obligations by transferring the promised services to the customers. A service is transferred to a customer when, or as, the customer obtains control of that service. A performance obligation may be satisfied at a point in time or over time. Revenue from a performance obligation satisfied at a point in time is recognized at the point in time that the Company determines the customer obtains control over the promised service. Revenue from a performance obligation satisfied over time is recognized by measuring the Company's progress in satisfying the performance obligation in a manner that depicts the transfer of the services to the customer. The amount of revenue recognized reflects the consideration the Company expects to receive in exchange for those promised services (i.e., the "transaction price"). In determining the transaction price, the Company considers multiple factors, including the effects of variable consideration, if any.

The Company's revenues from contracts with customers are recognized when the performance obligations are satisfied at an amount that reflects the consideration expected to be received in exchange for such services. The majority of the Company's performance obligations are satisfied at a point in time and are typically collected from customers by debiting their brokerage account with the Company.

***Nature of Services***

The Company's main sources of revenues from contracts with customers are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Commissions* are charged to customers for order execution services and trade clearing and settlement services. These services represent a single performance obligation as the services are not separately identifiable in the context of the contract. The Company recognizes revenue at a point in time at the execution of the order (i.e., trade date). Commissions are generally collected from cleared customers on trade date and from non-cleared customers monthly. Commissions also include payments for order flow received from IBKR Lite<sup>SM</sup> liquidity providers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Market data fees* are charged to customers for market data services to which they subscribe that the Company delivers. The Company recognizes revenue monthly as the performance obligation is satisfied over time by continually providing market data for the period. Market data fees are collected monthly, generally in advance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Risk exposure fees* are charged to customers who carry positions with a market risk that exceeds defined thresholds. The Company recognizes revenue daily as the performance obligation is satisfied at a point in time by the Company taking on the additional risk of account liquidation and potential losses due to insufficient margin. Risk exposure fees are collected daily.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Payments for order flow* are earned from various options exchanges based upon options trading volume originated by the Company that meets certain criteria. The Company recognizes revenue daily as the performance obligation is satisfied at a point in time on customer orders that qualify for payments subject to exchange-mandated programs. Payments for order flow are collected monthly, in arrears.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*FDIC sweep fees* are earned from the banks that participate in the Company's Insured Bank Deposit Sweep Program with respect to the Company's customers' funds deposited with each participating bank. The Company recognizes revenue daily as the performance obligation is satisfied when customer funds are swept to their FDIC insured accounts with the participating banks.

The Company also earns revenues from other services, including minimum activity fees, order cancelation or modification fees, position transfer fees, telecommunications fees, and withdrawal fees, among others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Reported in "Other fees and services" in the condensed consolidated statements of comprehensive income.

***Receivables and Contract Balances***

Receivables arise when the Company has an unconditional right to receive payment under a contract with a customer and are derecognized when the cash is received. Receivables of $45 million and $34 million, as of March 31, 2026 and December 31, 2025, respectively, are reported in "Other assets" in the condensed consolidated statements of financial condition.

Contract assets arise when the revenue associated with the contract is recognized before the Company's unconditional right to receive payment under a contract with a customer (i.e., unbilled receivable) and are derecognized when either it becomes a receivable or the cash is received. Contract assets are reported in "Other assets" in the condensed consolidated statements of financial condition. As of March 31, 2026 and December 31, 2025, there were no contract asset balances outstanding.

Contract liabilities arise when customers remit contractual cash payments in advance of the Company satisfying its performance obligations under the contract and are derecognized when the revenue associated with the contract is recognized either when a milestone is met triggering the contractual right to bill the customer or when the performance obligation is satisfied. Contract liabilities are reported in "Accounts payable, accrued expenses and other liabilities" in the condensed consolidated statements of financial condition. As of March 31, 2026 and December 31, 2025, there were no contract liability balances outstanding.

**10. Employee Incentive Plans**

*Defined Contribution Plan*

The Company offers substantially all employees of U.S.-based operating subsidiaries who have met minimum service requirements the opportunity to participate in defined contribution retirement plans qualifying under the provisions of Section 401(k) of the Internal Revenue Code. The general purpose of this plan is to provide employees with an incentive to make regular savings in order to provide additional financial security during retirement. This plan provides for the Company to match 50% of the employees' pre-tax contribution, up to a maximum of 10% of eligible earnings. The employee is vested in the matching contribution incrementally over six years of service. Reported in "Employee compensation and benefits" in the condensed consolidated statements of comprehensive income was $3 million and $2 million of plan contributions for the three months ended March 31, 2026 and 2025, respectively.

*2007 Stock Incentive Plan*

On February 26, 2026, the Company amended the 2007 Stock Incentive Plan to extend its term for a ten-year period through April 24, 2037, which was approved by the Company's stockholders at its 2026 Annual Meeting held on April 23, 2026. Under the Company's Stock Incentive Plan, up to 160 million shares of the Company's Class A common stock may be issued to satisfy vested restricted stock units granted to directors, officers, employees, contractors and consultants of the Company. The purpose of the Stock Incentive Plan is to promote the Company's long-term financial success by attracting, retaining and rewarding eligible participants.

As a result of the Company's organizational structure, a description of which can be found in "Business – Our Organizational Structure" in Part I, Item 1 of the Company's 2025 Annual Report on Form 10-K, filed with the SEC on February 27, 2026, there is no material dilutive effect upon ownership of common stockholders of issuing shares under the Stock Incentive Plan. The issuances do not dilute the book value of the ownership of common stockholders since the restricted stock units are granted at market value, and upon their vesting and the related issuance of shares of common stock, the ownership of IBG, Inc. in IBG LLC, increases proportionately to the shares issued. As a result of such proportionate increase in share ownership, the dilution upon issuance of common stock is borne by IBG LLC's majority member (i.e., noncontrolling interest), Holdings, and not by IBG, Inc. or its common stockholders. Additionally, dilution of earnings that may take place after issuance of common stock is reflected in EPS reported in the Company's financial statements. The EPS dilution can be neither estimated nor projected, but historically it has not been material.

The Stock Incentive Plan is administered by the Compensation Committee of the Company's Board of Directors. The Compensation Committee has discretionary authority to determine the eligibility to participate in the Stock Incentive Plan and establishes the terms and conditions of the awards, including the number of awards granted to each participant and all other terms and conditions applicable to such awards in individual grant agreements. Awards are expected to be made primarily through grants of restricted stock units. Stock Incentive Plan awards are subject to issuance over time. All previously granted but not yet earned awards may be canceled by the Company upon the participant's termination of employment or violation of certain applicable covenants before issuance, unless determined otherwise by the Compensation Committee.

**Notes to Unaudited Condensed Consolidated Financial Statements**

The Stock Incentive Plan provides that, upon a change in control, the Compensation Committee may, at its discretion, fully vest any granted but not yet earned awards under the Stock Incentive Plan, or provide that any such granted but not yet earned awards will be honored or assumed, or new rights substituted by the new employer on a substantially similar basis and terms and conditions substantially comparable to those of the Stock Incentive Plan.

The Company expects to continue to grant awards on or about December 31 of each year to eligible participants as part of an overall plan of equity compensation. In 2021, the Company's Compensation Committee approved a change to the vesting schedule for the Stock Incentive Plan. For awards granted on December 31, 2021 onwards, restricted stock units vest and become distributable to participants 20% on each vesting date, which is on or about May 9 of each year, assuming continued employment with the Company and compliance with non-competition and other applicable covenants. The vesting and distribution of grants prior to December 31, 2021 remain in accordance with the following schedule: (a) 10% on the first vesting date, which is on or about May 9 of each year; and (b) an additional 15% on each of the following six anniversaries of the first vesting.

Awards granted to directors vest and are distributed as follows: (a) one-time award granted to external directors on December 31 of the year of appointment vests over a five-year period (20% per year) commencing one year after the date of grant, and (b) annual awards granted to all directors on December 31 of each year are fully vested and distributed immediately on grant date. A total of 170,902 restricted stock units have been granted to the directors cumulatively since the plan's inception.

The table below presents Stock Incentive Plan awards granted and the related fair values since the plan's inception.

In accordance with the vesting schedule, outstanding awards vest and are distributed to participants yearly on or about May 9 of each year. At the end of each year, no vested awards remain undistributed.

Compensation expense related to the Stock Incentive Plan recognized in the condensed consolidated statements of comprehensive income was $33 million and $31 million for the three months ended March 31, 2026 and 2025, respectively.

**11. Income Taxes**

Income tax expense for the three months ended March 31, 2026 and 2025 differs from the U.S. federal statutory rate primarily due to the tax treatment of income attributable to noncontrolling interests in IBG LLC. These noncontrolling interests are held directly through a U.S. partnership. Accordingly, the income attributable to these noncontrolling interests is reported in the condensed consolidated statements of comprehensive income, but the related U.S. income tax expense attributable to these noncontrolling interests is not reported by the Company as it is generally the obligation of the noncontrolling interests. Income tax expense is also affected by the differing effective tax rates in foreign, state and local jurisdictions where certain of the Company's subsidiaries are subject to corporate taxation.

Deferred income taxes arise primarily due to the amortization of the deferred tax assets recognized in connection with the common stock offerings (see Note 4), differences in the valuation of financial assets and liabilities, net operating losses and for other temporary differences arising from the deductibility of compensation and depreciation expenses in different periods for accounting and income tax return purposes.

As of and for the three months ended March 31, 2026 and 2025, the Company had no material valuation allowances on deferred tax assets.

The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. As of March 31, 2026, the Company is no longer subject to U.S. Federal and State income tax examinations for tax years before 2016, and to non-U.S. income tax examinations for tax years prior to 2011.

Under U.S. GAAP, a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Based upon the Company's review of its federal, state, local and foreign income tax returns and tax filing positions, the Company has recorded a $11 million tax liability (including interest) for an uncertain tax position for an Internal Revenue Service audit of IRC Section 199 Domestic Production Activities Deduction and certain U.S. state income tax liabilities.

The enactment of H.R.1 (the "One Big Beautiful Bill Act") in July of 2025 introduced several corporate tax changes, many of which became effective January 1, 2026, including the extension of key Tax Cuts and Jobs Act provisions, enhanced bonus depreciation, modifications to interest limitation, modifications to the rules for Global Intangible Low Taxed Income ("GILTI"), which was renamed Net CFC Tested Income ("NCTI"), amongst other international tax rules modifications. Under ASC 740, companies are required to recognize the effects of enacted tax law changes in the period of enactment, including the remeasurement of deferred tax assets and liabilities and any related valuation allowances. The Company included the impact of H.R.1 on its condensed consolidated financial statements as of March 31, 2026 and December 31, 2025, respectively.

**12. Leases**

All of the Company's leases are classified as operating leases and primarily consist of real estate leases for corporate offices, data centers and other facilities. As of March 31, 2026, the weighted-average remaining lease term on these leases is approximately 7 years and the weighted-average discount rate used to measure the lease liabilities is approximately 4.91%. For the three months ended March 31, 2026, right-of-use assets obtained under new operating leases were $2 million. The Company's lease agreements do not contain any residual value guarantees, restrictions, or covenants.

**13. Commitments, Contingencies and Guarantees**

***Legal, Regulatory and Governmental Matters***

The Company is subject to certain pending and threatened legal, regulatory and governmental actions and proceedings that arise out of the normal course of business. Given the inherent difficulty of predicting the outcome of such matters, particularly in proceedings where claimants seek substantial or indeterminate damages, or which are in their early stages, the Company is generally not able to quantify the actual loss or range of loss related to such legal proceedings, the manner in which they will be resolved, the timing of their final resolution or the ultimate settlement. Management believes that the resolution of these matters will not have a material effect, if any, on the Company's business or financial condition, but may have a material impact on the results of operations for a given period.

The Company accounts for potential losses related to litigation in accordance with FASB ASC Topic 450, "Contingencies." As of March 31, 2026 and 2025, accruals for potential losses related to legal, regulatory and governmental actions and proceedings matters were not material.

*Class Action Matter* 

On December 18, 2015, a former individual customer filed a purported class action complaint against IB LLC, IBG, Inc., and Thomas Frank, Ph.D., the Company's Executive Vice President and former Chief Information Officer, in the U.S. District Court for the District of Connecticut. The complaint alleged that a purported class of IB LLC's customers were harmed by alleged "flaws" in the computerized system used to close out (i.e., liquidate) positions in customer brokerage accounts that have margin deficiencies. The complaint sought, among other things, undefined compensatory damages and declaratory and injunctive relief.

On September 28, 2016, the District Court issued an order granting the Company's motion to dismiss the complaint in its entirety, without leave to amend. On September 28, 2017, the plaintiff appealed to the United States Court of Appeals for the Second Circuit. On September 26, 2018, the Court of Appeals affirmed the dismissal of plaintiff's claims of breach of contract and commercially unreasonable liquidation but remanded plaintiff's claims for negligence back to the District Court. The Company's motion to dismiss plaintiff's subsequent amended complaint was denied on September 30, 2019. The Company's answer and counterclaim were filed on July 26, 2022. On August 25, 2023, the Court granted plaintiff's motion for class certification, certifying a class that consists of IB LLC account holders who are U.S. residents (with some exclusions) who had positions liquidated during the period of December 18, 2013 to the date of trial at prices outside of a "pricing corridor" defined in the Court's decision.

On August 15, 2025, the parties disclosed to the District Court that a settlement in principle had been reached. On January 20, 2026, the parties signed a class action settlement agreement, which received preliminary approval from the District Court on January 27, 2026. Under the terms of the settlement agreement, the Company will pay up to $5 million to the class and IB LLC will forgive approximately $1.8 million of debts owed by certain class members, with no admission of liability, in exchange for a release of claims. Final payment and debt forgiveness amounts are subject to certain class member opt-outs from the settlement. The Court's fairness hearing for the settlement is scheduled for June 17, 2026.

***Guarantees*** 

Certain of the operating subsidiaries provide guarantees to securities and commodities clearing houses and exchanges which meet the accounting definition of a guarantee under FASB ASC Topic 460, "Guarantees." Under standard membership agreements, clearing house and exchange members are required to guarantee collectively the performance of other members. Under the agreements, if a member becomes unable to satisfy its obligations, other members would be required to meet shortfalls. In the opinion of management, the operating subsidiaries' liability under these arrangements is not quantifiable and could exceed the cash and securities they have posted as collateral. However, the potential for these operating subsidiaries to be required to make payments under these arrangements is remote. Accordingly, no contingent liability is carried in the condensed consolidated statements of financial condition for these arrangements.

In connection with its retail brokerage business, IB LLC or other brokerage operating subsidiaries perform securities and commodities execution, clearance and settlement on behalf of their customers for whom they commit to settle trades submitted by such customers with the respective clearing houses. If a customer fails to fulfill its settlement obligations, the respective operating subsidiary must fulfill those settlement obligations. No contingent liability is carried on the condensed consolidated statements of financial condition for such customer obligations.

***Other Commitments*** 

Certain clearing houses, clearing banks and firms used by certain operating subsidiaries are given a security interest in certain assets of those operating subsidiaries held by those clearing organizations. These assets may be applied to satisfy the obligations of those operating subsidiaries to the respective clearing organizations.

**14. Segment Reporting and Geographic Information**

***Segment Reporting***

The Company has a single reportable segment, brokerage, which is managed on a consolidated basis since the Company's chief operating decision maker ("CODM") assesses performance and allocates resources on a consolidated basis based on income before income taxes and net income as reported on the consolidated statements of comprehensive income. The Company's CODM is its Chief Executive Officer and President.

The brokerage segment provides execution, clearing and settlement of trades globally for hedge and mutual funds, ETFs, registered investment advisors, proprietary trading groups, introducing brokers and individual investors. The brokerage segment derives revenue from customers in the U.S. and international markets by routing orders and executing and processing trades in stocks, options, futures, foreign exchange instruments ("forex"), bonds, mutual funds, ETFs, precious metals, and forecast contracts on more than 170 electronic exchanges and market centers in 40 countries and 29 currencies around the world, and by offering custody, prime brokerage, and securities and margin lending services to customers. In addition, brokerage customers can use its trading platform to trade certain cryptocurrencies through third-party cryptocurrency service providers that execute, clear and custody the cryptocurrencies.

Since the brokerage segment is managed on a consolidated basis, no reconciling items exist between segment and the consolidated amounts reported in these financial statements, including total assets and segment assets. The accounting policies of the brokerage segment are the same as those described in the summary of significant accounting policies in Note 2.

The table below presents selected financial information, including significant expenses, for the Company's single operating segment for the periods indicated.

The Company may extend credit to these related parties in connection with margin and securities loans. Such loans are (i) made in the ordinary course of business, (ii) are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the company, and (iii) do not involve more than the normal risk of collectability or present other unfavorable features.

During the year ended December 31, 2025, an affiliate of the Company's founder and Chairman, Mr. Thomas Peterffy, entered into agreements to fund certain advertising campaigns on behalf of IB LLC (the "Agreements"). The fees under the Agreements were paid directly by Mr. Peterffy's affiliate. On September 30, 2025, IB LLC amended its operating agreement to allow Mr. Peterffy to make additional capital contributions to IB LLC provided that such additional contributions shall not alter Mr. Peterffy's ownership percentage interests in IB LLC and shall be made for the benefit of IB LLC to offset certain expenses which Mr. Peterffy or his affiliates have contractually agreed to pay. During the three months ended March 31, 2026, Mr. Peterffy made additional non-cash capital contributions to IB LLC of less than $1 million to fund advertising campaigns pursuant to the Agreements. These contributions were made in Mr. Peterffy's capacity as a related party and were not made pursuant to any contractual obligation or agreement requiring repayment by the Company.

These contributions are reported in "Noncontrolling interest" in the condensed consolidated statements of financial condition and the related advertising expenses are reported in "General and administrative" and are allocated 100% to "Income attributable to non-controlling interest" in the condensed consolidated statements of comprehensive income.

**ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements and the related notes in Item 1, included elsewhere in this report. In addition to historical information, the following discussion also contains forward-looking statements that include risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth under the heading "Risk Factors" in our Annual Report on Form 10-K filed with the Securities Exchange Commission ("SEC") on February 27, 2026, and elsewhere in this report.

When we use the terms "we," "us," "our," and "IBKR," we mean IBG, Inc. and its subsidiaries (including IBG LLC) for the periods presented. Unless otherwise indicated, the term "common stock" refers to the Class A common stock of IBG, Inc.

On April 15, 2025, the Company announced its intention to effect a four-for-one forward split of its common stock. This was executed by the filing of an amendment to the Company's Certificate of Incorporation that, among other things (i) increased the Company's authorized shares of Class A common stock to 4,000,000,000 shares from 1,000,000,000 shares and (ii) increased the Company's authorized shares of Class B Common Stock to 1,000 shares from 100 shares to accommodate the stock split. The Company's Board of Directors subsequently authorized the stock split and each holder of record of common stock as of the close of market on June 16, 2025, received three additional shares of common stock. All prior period share and per share amounts presented herein have been retroactively adjusted to reflect the stock split.

**Introduction**

**Business Environment**

During the quarter ended March 31, 2026 ("current quarter"), global equity markets were mixed, with most major market indices declining amid uncertainties related to ongoing geopolitical conflicts and inflationary pressures, including those associated with rising oil prices. In the Americas, U.S. equity markets began the quarter strongly in January but declined over the rest of the period, with the S&P 500<sup>®</sup> index decreasing 4.6% compared to the prior quarter, while Canadian markets posted modest gains. Most European markets also declined. In the Asia-Pacific region, performance was mixed, with declines in China, Hong Kong and Australia, and gains in Japan.

Within the U.S., market performance diverged as investors rotated away from large-cap technology stocks into commodity-linked sectors, particularly energy. The decline in the S&P 500<sup>®</sup> index was driven in part by the group of large-cap technology companies commonly referred to as the "Magnificent Seven", each of which underperformed the broader market, resulting in relative outperformance by the remainder of the index.

Inflationary pressures re-emerged during the quarter, contributing to uncertainty regarding monetary policy across several major economies. Most central banks maintained policy interest rates and adopted a cautious, wait-and-see approach, as ongoing geopolitical conflicts and trade policy uncertainty reduced the likelihood of near-term rate cuts. As a result, expectations for additional monetary easing faded, weighing on market sentiment. Retail investor participation remained elevated, with continued engagement in equity, futures and options markets.

The following is a summary of the key economic drivers that affect our business and how they compared to the prior-year quarter:

*Global trading volumes.* Worldwide, equity trading volumes at most major venues increased during the current quarter compared to the prior-year quarter. In the U.S., according to industry data, average daily volume increased by 27% in listed cash equities, 20% in exchange-listed equity-based options and 22% in futures, each compared to the prior-year quarter. Options trading volumes continue to benefit from the growing popularity of shorter-dated contracts. In futures markets, volumes increased across all major product categories, including metals, energy, interest rates, equity indices, agriculture products and foreign exchange, as market participants sought to manage exposure to ongoing economic and geopolitical uncertainties.

These market dynamics produced strong results across our major product types. Customer trading volumes in equities, options, and futures increased by 25%, 16%, and 20%, respectively, compared to the prior-year quarter, though foreign exchange volumes decreased by 12% over the same period.

Note that while U.S. cash equities, options and futures volumes are readily comparable measures, they reflect most but not all of the global volumes that generate our commission revenue. See ''Trading Volumes and Customer Statistics'' below in this Item 7 for additional details regarding our trade volumes, contract and share volumes, and customer statistics.

*Volatility*. U.S. market volatility, as measured by the average Chicago Board Options Exchange Volatility Index (''VIX <sup>®</sup>''), increased by 10%, from an average of 18.5 in the prior-year quarter to 20.4 in the current quarter, still below the elevated levels reached in 2020 and 2022. In general, higher volatility typically enhances our performance because it often correlates positively with customer trading activity across product types.

*Interest Rates*. The U.S. Federal Reserve maintained the benchmark federal funds rate during the quarter, after cutting it three times in the second half of 2025 (September, October and December) by a total of 75 basis points. This resulted in a target range of 3.50% to 3.75% at year end, the lowest level since late 2022. During the current quarter, the U.S. Treasury yield curve inversion from the short- to medium-term substantially flattened, before rising steeply toward longer-term rates. In most countries with developed financial markets, benchmark interest rates also remained unchanged during the current quarter as inflationary pressures resurfaced and central banks adopted a cautious approach before adjusting monetary policy.

Lower U.S. benchmark rates reduce the interest we earn on our segregated cash, the majority of which is invested in short-term U.S. government securities and related instruments. A relatively flat near-term yield curve and uncertainty over future U.S. Federal Reserve rate policy have led us to maintain a short duration portfolio, all of which matured within three months at March 31, 2026, to more closely match our asset and liability maturities on our interest-sensitive assets. Further, our margin balances are tied to benchmark rates, so lower rates also limit the interest we earn on margin lending to our customers. We continue to offer among the lowest rates in the industry on margin lending, and we believe our low rates are an important feature that attracts customers to our platform.

As an offset, lower rates also reduce our interest expense. For example, in U.S. dollars we pay interest to customers on their qualified cash balances when the federal funds effective rate is above 0.50%, which it has been since May 2022. Any rate cuts are passed through to our customers, so we maintain a 0.50% spread. We believe the attractive rates we pay on customer cash are among the highest in the industry and are another important feature that draws customers to our platform.

[**<u>**Table of Contents**</u>**](#toc_page)

Net interest income on margin lending rose compared to the prior-year quarter. This increase was due to the growth in margin loan balances in the current active market environment, despite the decline in the average federal funds effective rate to 3.64% in the current quarter from 4.33% in the prior-year quarter.

Higher average balances contributed to a 17% rise in net interest income over the prior-year quarter. Net interest margin declined from 2.10% in the prior-year quarter to 1.88% in the current quarter primarily due to lower interest rates.

*Currency fluctuations*. As a global broker trading on exchanges around the world in multiple currencies, we are exposed to foreign currency risk. We actively manage this exposure by keeping our equity in proportion to a defined basket of 10 currencies we call the ''GLOBAL'' to diversify our risk and to align our hedging strategy with the currencies that we use in our business. Because we report our financial results in U.S. dollars, the change in the value of the GLOBAL versus the U.S. dollar affects our earnings. During the current quarter, the value of the GLOBAL, as measured in U.S. dollars, decreased 0.30% compared to its value at December 31, 2025, which had a negative impact on our comprehensive earnings for the current year. A discussion of our approach for managing foreign currency exposure is contained in Part I, Item 3 of this Quarterly Report on Form 10-Q entitled "Quantitative and Qualitative Disclosures about Market Risk."

**Financial Overview**

We report non-GAAP financial measures, which exclude certain items that may not be indicative of our core operating results and business outlook and are useful in evaluating the operating performance of our business. See the "Non-GAAP Financial Measures" section below in this Item 2 for additional details.

Diluted earnings per share were $0.59 for the current quarter, compared to diluted earnings per share of $0.48 for the prior-year quarter. Adjusted diluted earnings per share were $0.60 for the current quarter and $0.47 for the prior-year quarter. The calculation of diluted earnings per share is detailed in Note 4 – "Equity and Earnings per Share" to the unaudited condensed consolidated financial statements in Part 1, Item 1 of this Quarterly Report on Form 10-Q.

For the current quarter, our net revenues were $1,669 million and income before income taxes was $1,288 million, compared to net revenues of $1,427 million and income before income taxes of $1,055 million in the prior-year quarter. Adjusted net revenues were $1,680 million and adjusted income before income taxes was $1,299 million, compared to adjusted net revenues of $1,396 million and adjusted income before income taxes of $1,024 million in the prior-year quarter.

Financial highlights for the current quarter (compared to the prior-year quarter):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Commission revenue increased 19% to $613 million on higher customer trading volumes. Customer trading volume in stocks, futures and options increased 25%, 20% and 16%, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net interest income increased 17% to $904 million on higher average customer margin loans and customer credit balances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Other fees and services increased 10% to $86 million, led by increases of $2 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 $3 million in risk exposure fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Execution, clearing and distribution fees decreased 12% to $106 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Pretax profit margin was 77% for the current quarter compared to 74% in the prior-year quarter. Adjusted pretax profit margin for the current quarter was 77% compared to 73% in the prior-year quarter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total equity as of March 31, 2026, was $21.3 billion.

In connection with our currency diversification strategy, as of March 31, 2026, approximately 25% of our equity was denominated in currencies other than the U.S. dollar. In the current quarter, our currency diversification strategy decreased our comprehensive earnings by $53 million (compared to an increase of $127 million in the prior-year quarter), as the U.S. dollar value of the GLOBAL decreased by approximately 0.30% compared to its value as of December 31, 2025. The effects of our currency diversification strategy are reported as (1) a component of "Other income" (gain of $26 million) in the condensed consolidated statements of comprehensive income and (2) other comprehensive income ("OCI") (loss of $79 million) in the condensed consolidated statements of financial condition and the condensed consolidated statements of comprehensive income. The full effect of the GLOBAL is captured in comprehensive income.

**Certain Trends and Uncertainties** 

We believe that our current operations may be favorably or unfavorably impacted by the following trends and uncertainties that may affect our financial condition and results of operations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Retail participation in the equity markets has fluctuated in the past due to investor sentiment, market conditions and a variety of other factors. Retail transaction volumes may not be sustainable and are not predictable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Consolidation among market centers may adversely affect the value of our IB SmartRouting<sup>SM</sup> software.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Competition among broker-dealers may continue to intensify.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Benchmark interest rates tend to fluctuate with economic conditions. Changes in interest rates may not be predictable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Fiscal and/or monetary policy may change and impact the financial services business and securities markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•New legislation or modifications to existing regulations and rules could occur in the future. Scrutiny in the use of artificial intelligence ("AI") and information security by regulatory and legislative authorities has increased.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The impact of a pandemic or other public health emergency will depend on numerous evolving factors that cannot be accurately predicted, including the duration and spread of the pandemic, governmental regulations in response to the pandemic, and the effectiveness of vaccinations and other medical advancements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We continue to be exposed to the risks and uncertainties of doing business in international markets, particularly in the heavily regulated brokerage industry. Such risks and uncertainties include political, economic and financial instability, and foreign policy changes. For example, tensions between the U.S. and China have escalated in recent years, and changes in Chinese governmental oversight of the Chinese and Hong Kong capital markets could result in adverse effects on our business and loss of assets we hold in the region. Additionally, although our direct and indirect exposures to Russia, Ukraine and the Middle East are not material, the war in Ukraine and the conflict in the Middle East and related sanctions have created substantial uncertainty in the global economy and financial markets. Finally, government actions such as tariff policy changes may create uncertainty that affects volumes and volatility in the financial markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Our remaining market making activities, while not material, will continue to be impacted by market structure changes, market conditions, the level of automation of competitors, and the relationship between actual and implied volatility in the equities markets.

See "Risk Factors" in Part I, Item 1A of our Annual Report on Form 10-K, filed with the SEC on February 27, 2026, and elsewhere in this report for a discussion of other risks that may affect our financial condition and results of operations.

**Three Months Ended March 31, 2026 ("current quarter") compared to the Three Months Ended March 31, 2025 ("prior-year quarter")**

***Net Revenues***

Total net revenues, for the current quarter, increased $242 million, or 17%, compared to the prior-year quarter, to $1,669 million. The increase in net revenues was due to higher net interest income, commissions, other fees and services, and other income.

*Commissions*

We earn commissions from our cleared customers for whom we act as an executing and clearing broker and from our non-cleared customers for whom we act as an execution-only broker. Our commission structure allows customers to choose between (1) an all-inclusive fixed, or "bundled", rate; (2) a tiered, or "unbundled", rate that offers lower commissions for high volume customers where we pass through regulatory and exchange fees; and (3) our IBKR Lite<sup>SM</sup> offering, which provides commission-free trades on U.S. exchange-listed stocks and ETFs. IBKR Lite<sup>SM</sup> trades generate payments from market makers and others to whom we route these orders, which are reported in commissions. Our commissions are geographically diversified around the world, though a substantial majority are generated on products traded in the U.S.

Commissions, for the current quarter, increased $99 million, or 19%, compared to the prior-year quarter, to $613 million, driven by higher customer trading volumes in stocks, futures and options. Total customer stock share and futures and options contract volumes increased 25%, 20% and 16%, respectively. Total DARTs for the current quarter increased 24% to 4.4 million, compared to 3.5 million for the prior-year quarter. Average commission per commissionable order for cleared customers decreased 3% to $2.69 for the current quarter compared to $2.76 for the prior-year quarter, primarily due to smaller order sizes in stocks; greater capture of liquidity rebates; and a reduction in the SEC transaction fee rate to zero in the second quarter of 2025. As pass-throughs, the liquidity rebates and SEC fees affect both our commission revenues and our execution costs.

*Other Fees and Services* 

We earn fee income on services provided to customers, which includes market data fees, risk exposure fees, payments for order flow from exchange-mandated programs, FDIC sweep fees, and other fees and services charged to customers.

Other fees and services, for the current quarter, increased $8 million, or 10%, compared to the prior-year quarter, to $86 million, driven by a $2 million increase in FDIC sweep fees on higher customer balances, a $2 million increase in market data fees due to our growing customer base, and a $2 million increase in payments for order flow from exchange-mandated programs driven by higher customer trading volume; partially offset by a $3 million decrease in risk exposure fees as customers exhibited more cautious risk-taking behavior.

*Other Income* 

Other income consists of foreign exchange gains (losses) from our currency diversification strategy, gains (losses) from principal transactions, gains (losses) from our equity method and other investments, and other revenue not directly attributable to our core business offerings. A discussion of our approach to managing foreign currency exposure is contained in Part I, Item 3 of this Quarterly Report on Form 10-Q entitled "Quantitative and Qualitative Disclosures about Market Risk."

Other income, for the current quarter, increased $1 million, or 2% compared to the prior-year quarter, to $66 million. This increase was mainly due to $23 million related to our investing and trading activities and $6 million related to our currency diversification strategy, partially offset by $27 million related to our strategic investment in Up Fintech Holding Limited ("Tiger Brokers"), which lost $16 million in the current quarter compared to a gain of $11 million in the prior-year quarter.

*Interest Income and Interest Expense* 

We earn interest on margin lending to customers that is secured by marketable securities and currency balances these customers hold with us; from our investments in U.S. and foreign government securities; from borrowing and lending securities; on deposits (in positive interest rate currencies) with banks; and on certain customers' cash balances in negative rate currencies. We pay interest on customer cash balances (in sufficiently positive interest rate currencies); for borrowing and lending securities; on deposits (in negative interest rate currencies) with banks; and on our borrowings.

Net interest income (interest income less interest expense), for the current quarter, increased $134 million, or 17%, compared to the prior-year quarter, to $904 million. The increase in net interest income was driven by higher average customer margin loans and customer credit balances, partially offset by lower benchmark interest rates.

------

[**<u>**Table of Contents**</u>**](#toc_page)

Net interest income on customer balances, for the current quarter, increased $103 million compared to the prior-year quarter, driven by increases of $39.3 billion, $24.8 billion and $17.0 billion in average customer credit balances, margin loans, and segregated cash and securities, respectively. Yields on all three components decreased as rates have declined worldwide. See the "Business Environment" section above in this Item 2 for a further discussion about the change in interest rates in the current quarter.

The Company measures return on interest-earning assets using net interest margin ("NIM"). NIM is computed by dividing the annualized net interest income by the average interest-earning assets for the period. Interest-earning assets consist of cash and securities segregated for regulatory purposes (including U.S. government securities and securities purchased under agreements to resell), customer margin loans, securities borrowed, other interest-earning assets (solely firm assets) and customer cash balances swept into FDIC-insured banks as part of our Insured Bank Deposit Sweep Program. Interest-bearing liabilities consist of customer credit balances, securities loaned, and other interest-bearing liabilities.

Yields are generally a reflection of benchmark interest rates in each currency in which the Company and its customers hold cash balances. Because a meaningful portion of customer cash and margin loans are denominated in currencies other than the U.S. dollar, changes in U.S. benchmark interest rates do not impact the total amount of segregated cash and securities, customer margin loans and customer credit balances. Furthermore, because interest, when benchmark rates are at sufficiently high levels, is paid only on eligible cash credit balances (i.e., balances over $10 thousand or equivalent, in securities accounts with over $100 thousand in equity, and in smaller accounts at reduced rates), changes in benchmark interest rates are not passed through to the total amount of customer credit balances. Finally, the Company's policies with respect to currencies with near zero or negative interest rates impact the overall yields on segregated cash and customer credit balances as effective interest rates in those currencies move above or below zero.

We earn income on securities loaned and borrowed to support customer long and short stock holdings in margin accounts.

A securities lending transaction generates (1) net interest earned on lending a security, which is based on supply and demand for that security, and (2) interest earned on the cash collateral deposited for the loan of that security, which is based on benchmark interest rates. Interest on this collateral is reported as net interest on segregated cash, since cash collateral from securities lending is held in specially-designated bank accounts for the benefit of customers, in accordance with U.S. customer protection rules. Generally, as benchmark interest rates rise, while the overall revenue generated from a securities lending transaction may not change, the portion derived from interest earned on the cash collateral, which is classified as net interest income on "Segregated cash and securities, net" increases, while the portion classified as "Securities borrowed and loaned, net" decreases.

In the current quarter, average securities borrowed balances increased 84%, to $8.9 billion, and average securities loaned balances increased 58%, to $25.6 billion, compared to the prior-year quarter. Net interest earned from securities lending is affected by the level of demand for securities positions held by our customers that investors are looking to sell short. During the current quarter, net interest earned from securities lending transactions increased $23 million, or 230%, compared to the prior-year quarter, driven by (1) our growing account base, which increases our inventory of attractive stocks to lend, including international securities; (2) the interest we pay on short cash balances, which makes us attractive to investors who utilize short selling; (3) our fully-paid lending program shares proceeds with clients generally on a 50/50 basis, which appeals to investors looking to maximize the return on their portfolios; and (4) more activity in some of the typical drivers of securities lending, including IPOs and merger & acquisition activity. However, as noted above, the rise in benchmark interest rates from near zero in 2022 has shifted a portion of the interest reported as generated by lending securities to interest income on segregated cash (see further explanation above). It should be noted that securities lending transactions entered into to support customer activity may produce interest income (expense) that is offset by interest expense (income) related to customer balances.

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 below, the total net interest income related to our securities lending activities would have been $269 million in the current quarter, compared to $186 million in the prior-year quarter. 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 below, so it would have no effect on our overall net interest income or net interest margin.

Our Stock Yield Enhancement Program provides an opportunity for customers with fully-paid stock to allow us to lend it out. We pay customers a rebate on the cash collateral generally equal to 50% of a market-based rate for lending the shares. We place cash and/or U.S. Treasury securities as collateral securing the loans in the customer's account, which is held in segregated accounts or at an affiliate acting as collateral agent for the benefit of our customer.

This item is not recorded in the condensed consolidated statements of financial condition. Income derived from program deposits is reported in other net interest income in the table above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.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).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.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 condensed consolidated statements of comprehensive income. For the three months ended March 31, 2026 and 2025, $11 million and $8 million were reported in other fees and services, respectively; and $38 million and $16 million were reported in other income, respectively.

***Non-Interest Expenses***

Non-interest expenses, for the current quarter, increased $9 million, or 2%, compared to the prior-year quarter, to $381 million, mainly due to a $13 million increase in employee compensation and benefits, a $6 million increase in general and administrative expenses, and a $3 million increase in occupancy, depreciation and amortization expenses; partially offset by a $15 million decrease in execution, clearing and distribution fees. As a percentage of total net revenues, non-interest expenses were 23% for the current quarter and 26% for the prior-year quarter.

------

[**<u>**Table of Contents**</u>**](#toc_page)

*Execution, Clearing and Distribution Fees* 

Execution, clearing and distribution fees include the costs of executing and clearing trades, net of liquidity rebates received from various exchanges and market centers, as well as regulatory fees and market data fees. Execution fees are paid primarily to electronic exchanges and market centers on which we trade. Clearing fees are paid to clearing houses and clearing agents. Market data fees, which are associated with market data revenue included in other fees and services, are paid to third parties to receive streaming price quotes and related information.

Execution, clearing and distribution fees, for the current quarter, decreased $15 million, or 12%, compared to the prior-year quarter, to $106 million, mainly driven by a $24 million decrease in regulatory fees as the SEC Section 31 transaction fee rate was reduced to zero on May 14, 2025, and by greater capture of liquidity rebates from certain exchanges on higher customer trading volumes in stocks and options. SEC fees, as with other regulatory fees, are passed through to customers. As a percentage of total net revenues, execution, clearing and distribution fees were 6% for the current quarter and 8% for the prior-year quarter.

*Employee Compensation and Benefits*

Employee compensation and benefits include salaries, bonuses and other incentive compensation plans, group insurance, contributions to benefit programs and other related employee costs.

Employee compensation and benefits expenses, for the current quarter, increased $13 million, or 8%, compared to the prior-year quarter, to $167 million, associated with a combination of staffing increases and inflation. The average number of employees increased 6% to 3,207 for the current quarter, compared to 3,013 for the prior-year quarter. As we continue to grow, our focus on automation has allowed us to increase our staff at a relatively modest pace. As a percentage of total net revenues, employee compensation and benefits expenses were 10% for the current quarter and 11% for the prior-year quarter.

*Occupancy, Depreciation and Amortization*

Occupancy expenses consist primarily of rental payments on office and data center leases and related occupancy costs, such as utilities. Depreciation and amortization expenses result from the depreciation of fixed assets, such as computing and communications hardware, as well as amortization of leasehold improvements and capitalized in-house software development.

Occupancy, depreciation and amortization expenses, for the current quarter, increased $3 million, or 13%, compared to the prior-year quarter, to $27 million, mainly due to higher rent expense for new offices. As a percentage of total net revenues, occupancy, depreciation and amortization expenses were 2% for both the current quarter and the prior-year quarter.

*Communications* 

Communications expenses consist primarily of the cost of voice and data telecommunications lines supporting our business, including connectivity to exchanges and market centers around the world.

Communications expenses, for the current quarter, increased $2 million, or 20%, compared to the prior-year quarter, to $12 million. As a percentage of total net revenues, communications expenses were 1% for both the current quarter and the prior-year quarter.

*General and Administrative*

General and administrative expenses consist primarily of advertising; professional services expenses, such as legal and audit work; legal and regulatory matters; and other operating expenses.

General and administrative expenses, for the current quarter, increased $6 million, or 10%, compared to the prior-year quarter, to $68 million, driven primarily by a $7 million increase in advertising expenses. As a percentage of total net revenues, general and administrative expenses were 4% for both the current quarter and the prior-year quarter.

*Customer Bad Debt*

Customer bad debt expense consists primarily of losses incurred by customers in excess of their assets with us, net of amounts recovered by us.

Customer bad debt expense, for the current quarter, was unchanged from the prior-year quarter, at $1 million.

[**<u>**Table of Contents**</u>**](#toc_page)

*Income Tax Expense* 

We pay U.S. federal, state and local income taxes on our taxable income, which is proportional to the percentage we own of IBG LLC. Also, our operating subsidiaries are subject to income tax in the respective jurisdictions in which they operate.

Income tax expense, for the current quarter, increased $26 million, or 29%, compared to the prior-year quarter, to $117 million, primarily due to (1) higher income before taxes at our operating subsidiaries outside the U.S.; (2) higher income before income taxes subject to U.S. income tax at IBG, Inc.; and (3) IBG, Inc.'s higher average ownership percentage of IBG LLC, which rose from 25.8% in the prior-year quarter to 26.3% in the current quarter.

*Operating Results*

Income before income taxes, for the current quarter, increased $233 million, or 22%, compared to the prior-year quarter, to $1,288 million. Pretax profit margin was 77% for the current quarter and 74% for the prior-year quarter.

Comparing our operating results for the current quarter to the prior-year quarter using non-GAAP financial measures, adjusted net revenues were $1,680 million, up 20%; adjusted income before income taxes was $1,299 million, up 27%; and adjusted pre-tax profit margin was 77% for the current quarter compared to 73% for the prior-year quarter. See the "Non-GAAP Financial Measures" section below in this Item 2 for additional details.

------

[**<u>**Table of Contents**</u>**](#toc_page)

**Non-GAAP Financial Measures**

We use certain non-GAAP financial measures as additional measures to enhance the understanding of our financial results. These non-GAAP financial measures include adjusted net revenues, adjusted income before income taxes, adjusted net income available for common stockholders and adjusted diluted earnings per share ("EPS"). We believe that these non-GAAP financial measures 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. We believe these non-GAAP financial measures are useful to investors and analysts in evaluating the operating performance of the business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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 investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•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.

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. In the event an investment is sold prior to maturity, accumulated gains (losses) are realized and previously accumulated non-GAAP adjustments are reversed in the period of sale.

We also report compensation and benefits expenses as a percentage of adjusted net revenues, as we believe this measure is useful to investors and analysts in evaluating the growth of our workforce in relation to the growth of our core revenues.

These non-GAAP financial measures should be considered in addition to, rather than as a substitute for, measures of financial performance prepared in accordance with GAAP <sup>1</sup>.

**Liquidity and Capital Resources**

We maintain a highly liquid balance sheet. The majority of our assets consists of investments of customer funds, collateralized receivables arising from customer-related and proprietary securities transactions, and exchange-listed marketable securities, which are marked-to-market daily. Collateralized receivables consist primarily of customer margin loans, securities borrowed, and securities purchased under agreements to resell. As of March 31, 2026, total assets were $218.7 billion of which $216.5 billion, or 99.0%, were considered liquid.

Decisions on the allocation of capital are based upon, among other things, prudent risk management guidelines, potential liquidity and cash flow needs for current and future business activities, regulatory capital requirements, and projected profitability. Our Treasury department, Market Risk Committee, Enterprise Risk Management department and other management control groups assist in evaluating, monitoring and controlling the impact that our business activities have on our financial condition, liquidity and capital structure. The objective of these policies is to support our business strategies while ensuring ongoing and sufficient liquidity. Our significant capital comprises an aggregate across our many regulated subsidiaries, and in addition to supporting our current business and future expansion plans, we believe this financial strength provides our customers with a source of confidence.

Daily monitoring of liquidity needs and available collateral levels is undertaken to help ensure that an appropriate liquidity cushion, in the form of cash and unpledged collateral, is maintained at all times. We actively manage our excess liquidity and maintain significant borrowing capabilities through the securities lending markets and in the form of credit facilities with banks. As a general practice, we maintain sufficient levels of cash on hand to provide us with a buffer should we need immediately available funds for any reason. In addition, pursuant to our liquidity risk management plan we perform periodic liquidity stress tests, which are designed to identify and reserve liquid assets that would be available under market or idiosyncratic stress events. Based on our current level of operations, we believe our cash flows from operations, available cash and available borrowings will be adequate to meet our future liquidity needs for more than the next twelve months.

As of March 31, 2026, liability balances in connection with securities loaned and payables to customers were higher than their average monthly balances during the current quarter, and the short-term borrowings balance was lower than its average monthly balance during the current quarter.

Cash and cash equivalents held by our non-U.S. operating subsidiaries as of March 31, 2026, were $2,242 million ($2,019 million as of December 31, 2025). These funds are primarily intended to finance each individual operating subsidiary's local operations, and thus would not be available to fund U.S. domestic operations unless repatriated through payment of dividends to IBG LLC. As of March 31, 2026, we had no intention to repatriate any amounts from non-U.S. operating subsidiaries. With the enactment of the U.S. Tax Cuts and Jobs Act on December 22, 2017, we recognized a liability for the one-time transition tax on deemed repatriation of earnings of some of our foreign subsidiaries for the year ended December 31, 2017, which was paid over eight years ending in 2025. As a result, in the event dividends were to be paid to the Company in the future by a non-U.S. operating subsidiaries, the Company would not be required to accrue and pay income taxes on such dividends, except for foreign taxes in the form of dividend withholding tax, and in connection with accumulated other comprehensive income/loss from currency exchange rate changes not previously taxed in the U.S., if any, imposed on the recipient of the distribution or dividend distribution tax imposed on the payor of the distribution.

Historically, our consolidated equity has consisted primarily of accumulated retained earnings, which to date have been sufficient to fund our operations and growth. Our consolidated equity increased 22% to $21.3 billion as of March 31, 2026, from $17.5 billion as of March 31, 2025. This increase is attributable to total comprehensive income, partially offset by distributions and dividends paid during the last four quarters.

***Cash Flows*** 

The table below presents our cash flows from operating activities, investing activities and financing activities for the periods indicated.

---

| | | |
|:---|:---|:---|

| Effect of exchange rate changes on cash, cash equivalents, and restricted cash | (79) | 107 |
| Increase in cash, cash equivalents, and restricted cash | $3204 | $2440 |

---

Our cash, cash equivalents, and restricted cash (i.e., cash and cash equivalents that are subject to withdrawal or usage restrictions) increased by $3,204 million to $58.5 billion for the three months ended March 31, 2026.

***Operating Activities***

Our cash flows from operating activities are largely a reflection of the changes in customer credit and margin loan balances. We raised $3.6 billion in net cash from operating activities mainly driven by customer credit balances and securities loaned which increased $8.6 billion and $7.3 billion, respectively, and receivables from customers which decreased $3.9 billion; partially offset by securities segregated for regulatory purposes, which increased $15.4 billion.

***Investing Activities***

Our cash flows from investing activities are primarily related to other investments, capitalized internal software development, purchases and sales of memberships, trading rights and shares at exchanges where we trade, and strategic investments where such investments may enable us to offer better execution alternatives to our current and prospective customers, allow us to influence exchanges to provide competing products at better prices using sophisticated technology, or enable us to acquire either technology or customers faster than we could develop them on our own. We used net cash of $12 million in our investing activities primarily for purchases of property, equipment, and intangible assets, partially offset by distributions received and proceeds from sales of other investments.

***Financing Activities***

Our cash flows from financing activities are comprised of short-term borrowings, capital transactions, and payments made to Holdings under the Tax Receivable Agreement. Short-term borrowings from banks are part of our daily cash management in support of operating activities. Capital transactions consist primarily of quarterly dividends paid to common stockholders and related distributions paid to Holdings. We used net cash of $316 million in our financing activities, primarily for distributions to noncontrolling interests and dividends paid to common stockholders.

**Three months Ended March 31, 2025:** For a discussion of changes in cash flows for the three months ended March 31, 2025 refer to our Quarterly Report on Form 10-Q filed with the SEC on May 8, 2025.

***Regulatory Capital Requirements*** 

As of March 31, 2026, all operating subsidiaries were in compliance with their respective regulatory capital requirements. For additional information regarding our regulatory capital requirements see Note 15 – ''Regulatory Requirements'' to the unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.

**Capital Expenditures**

We expect capital expenditures to remain primarily focused on technology infrastructure, system capacity, cybersecurity, and regulatory requirements. Our capital expenditures are comprised of compensation costs of our software engineering staff for development of software for internal use and expenditures for computer, networking and communications hardware, and leasehold improvements. These expenditure items are reported as property, equipment, and intangible assets. Capital expenditures for property, equipment, and intangible assets were $26 million and $16 million for the three months ended March 31, 2026 and 2025, respectively. In the future, we plan to meet capital expenditure needs with cash from operations and cash on hand, as we continue our focus on technology infrastructure initiatives to further enhance our competitive position. In response to changing economic conditions, we believe we have the flexibility to modify our capital expenditures by adjusting them (either upward or downward) to match our actual performance. If we pursue any additional strategic acquisitions, we may incur additional capital expenditures.

[**<u>**Table of Contents**</u>**](#toc_page)

**Seasonality**

Our businesses are subject to seasonal fluctuations, reflecting varying numbers of market participants at times during the year, varying numbers of trading days from quarter-to-quarter, and declines in trading activity due to holidays. Typical seasonal trends may be superseded by market or world events, which can have a significant impact on prices and trading volume.

**Inflation**

Although we cannot accurately anticipate the effects of inflation on our operations, we believe that, for the past several years, inflation may have indirectly had a material impact on our results of operations. Inflation has been one of the factors driving our employee compensation and benefits expenses higher during the current period, although as a percentage of net revenues these expenses remain stable. Inflation may also be a contributing factor to general uncertainty in the markets in the foreseeable future. Statements about future inflation are subject to the risk that actual inflation and its effects may differ, possibly materially, due to, among other things, changes in economic growth, impact of supply chain disruptions, unemployment and consumer demand.

**Investments in U.S. Government Securities**

We invest in U.S. government securities to satisfy U.S. regulatory requirements. As a broker-dealer, unlike banks, we are required to mark these investments to market even though we intend to hold them to maturity. Sudden increases (decreases) in interest rates will cause mark-to-market losses (gains) on these securities, which are recovered (eliminated) if we hold them to maturity, as currently intended. As of March 31, 2026, all of our U.S. government securities had maturities within three months. The impact of changes in interest rates is further described in Part I, Item 3 of this Quarterly Report on Form 10-Q entitled "Quantitative and Qualitative Disclosures about Market Risk."

**Strategic Investments and Acquisitions**

We regularly evaluate potential strategic investments and acquisitions. We hold strategic investments in certain electronic trading exchanges, including BOX Options Exchange, LLC and Miami International Holdings Inc. We also hold strategic investments in certain businesses, including Zero Hash Holdings Ltd. (a crypto-service provider) and Next Securities Corporation (a South Korea-based securities company).

We intend to continue making acquisitions on an opportunistic basis, generally only when the acquisition candidate will, in our opinion, enable us to offer better execution alternatives to our current and prospective customers, allow us to influence exchanges to provide competing products at better prices using sophisticated technology, or enable us to acquire either technology or customers faster than we could develop them on our own.

As of March 31, 2026, there were no definitive agreements with respect to any material acquisition.

**Certain Information Concerning Off-Balance-Sheet Arrangements**

We may be exposed to a risk of loss not reflected in our condensed consolidated financial statements for futures products, which represent our obligations to settle at contracted prices, and which may require us to repurchase or sell in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk, as our cost to liquidate such futures contracts may exceed the amounts reported in our condensed consolidated statements of financial condition.

**Critical Accounting Policies and Estimates**

Our consolidated financial statements have been prepared in accordance with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements and accompanying notes. These estimates and assumptions are based on judgment and the best available information at the time. Therefore, actual results could differ materially from those estimates. We believe that the critical policies listed below represent the most significant estimates used in the preparation of our consolidated financial statements. See Note 2 – "Significant Accounting Policies" to the unaudited condensed consolidated financial statements for a summary of our significant accounting policies in Part I, Item 1 of this Quarterly Report on Form 10-Q.

***Contingencies***

Our policy is to estimate and accrue for potential losses that may arise out of litigation and regulatory proceedings, to the extent that such losses are probable and can be estimated. Significant judgment is required in making these estimates and our final liabilities may ultimately be materially different. Our total liability accrued with respect to litigation and regulatory proceedings is determined on a case by case basis and represents an estimate of probable losses based on, among other factors, the progress of each case, our experience with and industry experience with similar cases and the opinions and views of internal and external legal counsel. Given the inherent difficulty of predicting the outcome of litigation and regulatory matters, particularly in cases or proceedings in which substantial or indeterminate damages or fines are sought, or where cases or proceedings are in the early stages, we cannot estimate losses or ranges of losses for cases or proceedings where there is only a reasonable possibility that a loss may be incurred.

***Income Taxes***

Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits are based on enacted tax laws and reflect management's best assessment of estimated future taxes to be paid. We are subject to income taxes in both the U.S. and numerous foreign jurisdictions. Determining income tax expense requires significant judgment and estimates.

Deferred income tax assets and liabilities arise from temporary differences between the tax and financial statement recognition of the underlying assets and liabilities. In evaluating our ability to recover our deferred tax assets within the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations.

In projecting future taxable income, historical results are adjusted for changes in accounting policies and incorporate assumptions including the amount of future state, federal and foreign pre-tax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, three years of cumulative operating income (loss) are considered. Deferred income taxes have not been provided for U.S. tax liabilities or for additional foreign taxes on the unremitted earnings of foreign subsidiaries that have been indefinitely reinvested.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. For example, a number of jurisdictions, including the European Union countries, have enacted legislation to implement the Pillar Two framework established by the Organization for Economic Cooperation and Development, which generally imposes a minimum effective tax rate of 15% in each such jurisdiction. We record tax liabilities in accordance with Financial Accounting Standards Board ("FASB") ASC Topic 740 and adjust these liabilities when management's judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in payments that are different from the current estimates of these tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information becomes available.

We recognize that a tax benefit from an uncertain tax position may be recognized only when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. A tax position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement.

**Accounting Pronouncements Issued but Not Yet Adopted**

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are exposed to various market risks. Our exposures to market risks arise from assumptions built into our pricing models, equity price risk, foreign currency exchange rate fluctuations related to our international operations, changes in interest rates and risks relating to the extension of margin credit to our customers.

Market risk refers to the risk that a change in the level of one or more market prices, rates, indices, implied volatilities (the price volatility of the underlying instrument imputed from option prices), correlations or other market factors, such as market liquidity, will result in losses for a position or portfolio. Generally, we incur trading-related market risk as a result of our remaining market making activities, where the substantial majority of our Value-at-Risk ("VaR") for market risk exposures is generated. In addition, we incur non-trading-related market risk primarily from investment activities and from foreign currency exposure held in the equity of our foreign subsidiaries, i.e., our non-U.S. brokerage subsidiaries and information technology subsidiaries, and held to meet target balances in our currency diversification strategy.

We use various risk management tools in managing our market risk, which are embedded in our real-time market making systems. We employ certain hedging and risk management techniques to protect us from a severe market dislocation. Our risk management policies are developed and implemented by our Steering Committee, which is chaired by our Chief Executive Officer and comprised of senior executives of our various operating subsidiaries. The strategy of our remaining market making activities is to calculate quotes a few seconds ahead of the market and execute small trades at a tiny but favorable differential as a result. This strategy is made possible by our proprietary pricing model, which evaluates and monitors the risks inherent in our portfolio, assimilates external market data and reevaluates the outstanding quotes in our portfolio many times per second. Our model automatically rebalances our positions throughout each trading day to manage risk exposures on our options and futures positions and the underlying securities and will price the increased risk that a position would add to the overall portfolio into the bid and offer prices we post. Under risk management policies implemented and monitored primarily through our computer systems, reports to management, including risk profiles, profit and loss analysis and trading performance, are prepared on a real-time basis as well as daily and periodical bases. Although our remaining market making activities are completely automated, the trading process and our risk are monitored by a team of individuals who, in real time, observe various risk parameters of our consolidated positions. Our assets and liabilities are marked-to-market daily for financial reporting purposes and re-valued continuously throughout the trading day for risk management and asset/liability management purposes.

We use a covariant VaR methodology to measure, monitor and review the market risk of our market making portfolios, with the exception of fixed income products, and our currency exposures. The risk of fixed income products, which comprise primarily U.S. government securities, is measured using a stress test.

***Pricing Model Exposure***

As described above, our proprietary pricing model, which continuously evaluates and monitors the risks inherent in our portfolio, assimilates external market data and reevaluates the outstanding quotes in our entire portfolio many times per second. Certain aspects of the model rely on historical prices of securities. If the behavior of price movements of individual securities diverges substantially from what their historical behavior would predict, we might incur trading losses. We attempt to limit such risks by diversifying our portfolio across many different options, futures and underlying securities and avoiding concentrations of positions based on the same underlying security. Historically, our losses from these events have been immaterial in comparison to our annual trading profits.

***Foreign Currency Exposure***

As a result of our international activities and accumulated earnings in our non-U.S. subsidiaries, our income and equity are exposed to fluctuations in foreign exchange rates. For example, our non-U.S. subsidiaries are exposed to foreign exchange risks as described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Some of our non-U.S. subsidiaries support customer transactions in financial instruments, carry bank balances, and borrow and lend securities in various currencies in their regular course of business. At the end of each accounting period, these non-U.S. subsidiaries' assets and liabilities are revalued into their respective functional currencies for presentation in their financial statements. The resulting foreign currency gains or losses are reported in their income statements and, as translated into U.S. dollars for U.S. GAAP purposes, in our condensed consolidated statements of comprehensive income, as a component of "Other income."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•These non-U.S. subsidiaries' financial statements are presented in their respective functional currencies, as noted above. For U.S. GAAP purposes, at the end of each accounting period, each non-U.S. subsidiary's equity is translated at the then prevailing exchange rate into U.S. dollars and the resulting translation gain or loss is reported as OCI in our condensed consolidated statements of financial condition and condensed consolidated statements of comprehensive income.

------

[**<u>**Table of Contents**</u>**](#toc_page)

By periodically converting currency balances into functional currency, we substantially reduce the foreign currency exposures for each of these non-U.S. subsidiaries, which minimizes the impact of exchange rate changes to its income statement. However, historically, we have taken the approach of not hedging our consolidated foreign currency exposures to the U.S. dollar, based on the notion that the cost of constantly hedging over the years would amount to more than the random impact of rate changes on our non-U.S. dollar balances.

Instead, because we conduct business in many countries and many currencies and because we consider ourselves a global enterprise based in a diversified basket of currencies rather than a U.S. dollar-based company, we actively manage our global currency exposure by maintaining our equity in GLOBALs, a basket of currencies. Our risk management systems incorporate cash forex to hedge our currency exposure at little or no cost. Currency spot positions entered into as part of our currency diversification strategy are held by the parent holding company, IBG LLC.

The U.S. dollar value of the GLOBAL increased 0.99% as of March 31, 2026 compared to March 31, 2025. As of March 31, 2026, approximately 25% of our equity was denominated in currencies other than the U.S. dollar.

The effects of our currency diversification strategy appear in two places in the condensed consolidated financial statements: (1) as a component of "Other income" in the condensed consolidated statements of comprehensive income and (2) as OCI in the condensed consolidated statements of financial condition and the condensed consolidated statements of comprehensive income. The full effect of the GLOBAL is captured in the condensed consolidated statements of comprehensive income.

The table below presents a comparison of the U.S. dollar equivalent of the GLOBAL for the periods indicated.

***Interest Rate Risk***

We had no variable-rate debt outstanding as of March 31, 2026.

We pay our customers interest based on benchmark overnight interest rates in various currencies, when interest rates are above a benchmark rate plus a small spread, on cash balances above $10 thousand (or equivalent) in securities accounts holding more than $100 thousand and at lower, tiered rates for accounts holding less than $100 thousand (or equivalent) net asset value. In currencies, if any, with negative rates, we pass through the cost of holding certain cash balances to our customers; therefore, we charge our customers interest on these cash balances. In a normal rate environment, we typically invest a portion of these funds in U.S. government securities with maturities of up to two years, although given the current interest rate environment, at this time all such investments mature within three months. If interest rates were to increase rapidly and substantially, our net interest income would not increase proportionally with the interest rates for the portion of the funds invested at fixed yields. In addition, the mark-to-market changes in the value of these fixed rate securities will be reflected in other income, instead of net interest income. Our margin balances are priced to a benchmark rate plus a spread, with a minimum charge of 0.75% in U.S. dollars and most foreign currencies.

Based on customer balances and investments outstanding as of March 31, 2026, and assuming reinvestment of maturing instruments in instruments of short-term duration, an increase of 0.25% over current U.S. dollar interest rate levels would increase our net interest income by $82 million on an annualized basis, assuming the full effect of reinvestment at higher rates. A 0.25% increase in all the relevant non-U.S. dollar benchmark rates would increase our net interest income by $32 million on an annualized basis. Our interest rate sensitivity estimate contains separate assumptions for U.S. dollar rates from other currencies' rates and it isolates the effects of a rate increase on reinvestments. We do not approximate mark-to-market impact from interest rate changes; if U.S. government securities whose prices were to fall under these scenarios were held to maturity, as intended, then the reduction in other income would be temporary, as the securities would mature at par value. If such securities were sold prior to maturity, the loss would be realized and the proceeds reinvested at prevailing higher interest rates.

------

[**<u>**Table of Contents**</u>**](#toc_page)

We also face the potential for reduced net interest income from customer deposits and margin loans if benchmark rates were to fall. Based on customer balances and investments outstanding as of March 31, 2026, and assuming reinvestment of maturing instruments in instruments of short-term duration, a decrease in U.S. dollar interest rates of 0.25% would decrease our net interest income by $82 million on an annualized basis, assuming the full effect of reinvestment at lower rates. A 0.25% decrease in all the relevant non-U.S. dollar benchmark rates would decrease our net interest income by $35 million on an annualized basis.

We also face interest rate risk due to positions carried for our remaining market making activities to the extent that long or short stock positions may have been established for future or forward dates on options or futures contracts and the value of such positions is impacted by interest rates. The amount of such risk cannot be quantified, however, the current low level of market making positions does not indicate a material potential exposure.

***Dividend Risk***

We face dividend risk in our remaining market making activities as we derive revenues and incur expenses in the form of dividend income and expense, respectively, from our inventory of equity securities, and must make payments in lieu of dividends on short positions in equity securities within our portfolio. Projected future dividends are an important component of pricing equity options and other derivatives, and incorrect projections may lead to trading losses. The amount of such risk cannot be quantified, however, the current low level of market making positions does not indicate a material potential exposure.

***Margin Loans***

We extend margin loans to our customers, which are subject to various regulatory requirements. Margin loans are collateralized by cash and securities in the customers' accounts. The risks associated with margin credit increase during periods of fast market movements or in cases where collateral is concentrated and market movements occur. During such times, customers who utilize margin loans and who have collateralized their obligations with securities may find that the securities have a rapidly depreciating value and may not be sufficient to cover their obligations in the event of a liquidation. We are also exposed to credit risk when our customers execute transactions, such as short sales of options and equities that can expose them to risk beyond their invested capital.

We expect this kind of exposure to increase with the growth of our overall business. Because we indemnify and hold harmless our clearing houses and counterparties from certain liabilities or claims, the use of margin loans and short sales may expose us to significant off-balance-sheet risk if collateral requirements are not sufficient to fully cover losses that customers may incur and those customers fail to satisfy their obligations. As of March 31, 2026, we had $86.5 billion in margin loans extended to our customers. The amount of risk to which we are exposed from the margin loans we extend to our customers and from short sale transactions by our customers is unlimited and not quantifiable as the risk is dependent upon analysis of a potentially significant and undeterminable rise or fall in stock prices. Our account level margin requirements meet or exceed those required by Regulation T of the Board of Governors of the Federal Reserve and FINRA portfolio margin rules, as applicable. As a matter of practice, we enforce real-time margin compliance monitoring and liquidate customers' positions if their equity falls below required margin requirements.

We have a comprehensive policy implemented in accordance with regulatory standards to assess and monitor the suitability of investors to engage in various trading activities. To mitigate our risk, we also continuously monitor customer accounts to detect excessive concentration, large orders or positions, patterns of day trading and other activities that indicate increased risk to us.

Our credit exposure is to a great extent mitigated by our real-time margining system, which automatically evaluates each account throughout the trading day and closes out positions automatically for accounts that are found to be under-margined. While this methodology is effective in most situations, it may not be effective in situations where no liquid market exists for the relevant securities or commodities or where, for any reason, automatic liquidation for certain accounts has been disabled. Our Market Risk Committee continually monitors and evaluates our risk management policies, including the implementation of policies and procedures to enhance the detection and prevention of potential events to mitigate margin loan losses.

[**<u>**Table of Contents**</u>**](#toc_page)

***Value-at-Risk***

We estimate VaR using a historical approach, which uses the historical daily price returns of underlying assets as well as estimates of the end of day implied volatility for options. Our one-day VaR is defined as the unrealized loss in portfolio value that, based on historically observed market risk factors, would have been exceeded with a frequency of one percent, based on a calculation with a confidence interval of 99%.

Our VaR model generally takes into account exposures to equity and commodity price risk and foreign exchange rates.

We use VaR as one of a range of risk management tools. Among their benefits, VaR models permit the estimation of a portfolio's aggregate market risk exposure, incorporating a range of varied market risks and portfolio assets. One key element of the VaR model is that it reflects risk reduction due to portfolio diversification or hedging activities. However, VaR has various strengths and limitations, which include, but are not limited to: use of historical changes in market risk factors, which may not be accurate predictors of future market conditions, and may not fully incorporate the risk of extreme market events that are outsized relative to observed historical market behavior or reflect the historical distribution of results beyond the confidence interval; and reporting of losses in a single day, which does not reflect the risk of positions that cannot be liquidated or hedged in one day. A small proportion of market risk generated by trading positions is not included in VaR. The modeling of the risk characteristics of some positions relies on approximations that, under certain circumstances, could produce significantly different results from those produced using more precise measures. VaR is most appropriate as a risk measure for trading positions in liquid financial markets and will understate the risk associated with severe events, such as periods of extreme illiquidity.

The VaR calculation simulates the performance of the portfolio based on several years of daily price changes of the underlying assets and determines the VaR as the calculated loss that occurs at the 99<sup>th</sup> percentile.

Since the reported VaR statistics are estimates based on historical data, VaR should not be viewed as predictive of our future revenues or financial performance or of our ability to monitor and manage risk. There can be no assurance that our actual losses on a particular day will not exceed the indicated VaR or that such losses will not occur more than one time in 100 trading days. VaR does not predict the magnitude of losses which, should they occur, may be significantly greater than the VaR amount.

***Stress Test*** 

We estimate the market risk of our fixed income portfolio using a risk analysis model provided by a leading external vendor. For corporate bonds, this stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in five scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/-100 and +/-200 basis points. For U.S. government securities, the stress test is configured to calculate the change in value of each fixed income security in the portfolio over one day in three scenarios each of which represents a parallel shift of the U.S. Treasury yield curve. The scenarios are shifts of +/-50 basis points.
