2. Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated. These consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The consolidated financial information as of December 31, 2024 has been derived from audited financial statements not included herein. These unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) with respect to Form 10-Q and reflect all adjustments that, in the opinion of management, are normal and recurring, and that are necessary for a fair statement of the results for the interim periods presented. In accordance with such rules and regulations, certain disclosures that are normally included in annual financial statements have been omitted. Interim period operating results may not be indicative of the operating results for a full year.

Cash and Cash Equivalents

The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.

Investments

The Company determines the appropriate classification of securities at the time of purchase which are recorded in the Consolidated Statements of Financial Condition on the trade date. Securities are classified as available-for-sale or trading. Available-for-sale investments are carried at fair value with unrealized gains or losses reported in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition and realized gains or losses reported in other, net in the Consolidated Statements of Operations. Trading investments include U.S. Treasuries and are carried at fair value, with realized and unrealized gains or losses included in other, net in the Consolidated Statements of Operations.

The Company assesses whether an impairment loss on its available-for-sale debt securities has occurred due to declines in fair value or other market conditions. When the amortized cost basis of an available-for-sale debt security exceeds its fair value, the security is deemed to be impaired. The portion of an impairment related to credit losses is determined by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security and is recorded as a charge in the Consolidated Statements of Operations. The remainder of an impairment is recognized in accumulated other comprehensive loss if the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security prior to recovery.

Fair Value Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” A three-tiered hierarchy for determining fair value has been established that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as Level 1 (unadjusted quoted prices for identical assets or liabilities in active markets), Level 2 (inputs that are observable in the marketplace other than those inputs classified in Level 1) and Level 3 (inputs that are unobservable in the marketplace). The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of its money market funds, trading securities, available-for-sale securities and foreign currency forward contracts. All other financial instruments are short-term in nature and the carrying amounts reported on the Consolidated Statements of Financial Condition approximate fair value.

Receivables from broker-dealers, clearing organizations and customers include amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (“securities failed-to-deliver”) and cash deposits held at clearing organizations and clearing brokers to facilitate the settlement and clearance of matched principal transactions. Payables to broker-dealers, clearing organizations and customers include amounts payable for securities not received by the Company from a seller by the settlement date (“securities failed-to-receive”). Securities failed-to-deliver and securities failed-to-receive for transactions executed on a matched principal basis where the Company serves as a counterparty to both the buyer and the seller are recorded on a settlement date basis. The Company presents its securities failed-to-deliver and securities failed-to-receive balances on a net-by-counterparty basis within receivables from and payables to broker-dealers, clearing organizations and customers. The difference between the Company’s trade-date receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade date basis.

Allowance for Credit Losses

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. The Company continually monitors collections and payments from its customers and maintains an allowance for doubtful accounts. The allowance for credit losses is based on the estimated expected credit losses in accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific collection issues that have been identified. Account balances are grouped for evaluation based on various risk characteristics, including billing type, legal entity, and geographic region. Additions to the allowance for credit losses are charged to bad debt expense, which is included in general and administrative expense in the Company’s Consolidated Statements of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses.

The allowance for credit losses was $0.5 million and $1.0 million as of June 30, 2025 and December 31, 2024, respectively. The provision for bad debts and write-offs and other charges against the allowance for credit losses were immaterial for the three and six months ended June 30, 2025 and 2024, respectively.

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven years. The Company amortizes leasehold improvements on a straight-line basis over the lesser of the life of the improvement or the remaining term of the lease.

Software Development Costs

The Company capitalizes certain costs associated with the development of internal use software, including, among other items, employee compensation and related benefits and third-party consulting costs at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. Once the product is ready for its intended use, such costs are amortized on a straight-line basis over three to five years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.

Foreign Currency Translation and Forward Contracts

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the period; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are a component of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Transaction gains and losses are recorded in other, net in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to economically hedge its foreign currency transaction gains and losses. Realized and unrealized gains and losses on these forward contracts are included in other, net in the Consolidated Statements of Operations. The Company records the fair value of the forward contract asset in prepaid expenses and other assets or the fair value of the forward contract liability in accounts payable, accrued expenses and other liabilities in the Consolidated Statements of Financial Condition.

Revenue Recognition

The Company’s classification of revenues in the Consolidated Statements of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has four revenue streams as described below.

Commission Revenue – The Company charges its broker-dealer clients variable transaction fees for trades executed on its platforms and, under certain plans, distribution fees or monthly minimum fees to use the platforms for a particular product area. Variable transaction fees are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on the platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. Bonds that are more actively traded or that have shorter maturities generally generate lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. Under the Company’s disclosed trading transaction fee plans, variable transaction fees, distribution fees and unused monthly fee commitments are invoiced and recorded on a monthly basis.

For Open Trading trades that the Company executes between and among institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller, the Company earns its commission through the difference in price between the two trades. The commission is collected upon settlement of the trade, which typically occurs within one to two trading days after the trade date. For the majority of the Company’s U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis.

The Company also earns other commissions on equities and foreign exchange products for algorithmic trading services. These fees incorporate variable transaction fees, which are calculated as a percentage of the notional dollar volume traded and are billed on a monthly basis.

Information services – Information services includes data licensed to the Company’s broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. The nature and timing of each performance obligation may vary as these contracts are either subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services that are transferred at a point in time. Revenues for services transferred over time are recognized ratably over the contract period as the Company’s performance obligation is met, whereas revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period. The following table presents information services revenue by timing of recognition:

Post-trade services – Post-trade services revenue is generated from regulatory transaction reporting, trade publication and post-trade matching services. Customers are generally billed monthly in arrears, and revenue is recognized in the period transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. The Company also generates one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is completed.

The majority of the Company’s information services and post-trade services contracts are short-term in nature with durations of one year or less. For contracts with original durations extending beyond one year, the aggregate amount of the transaction price allocated to remaining performance obligations was $40.4 million as of June 30, 2025. The Company expects to recognize revenue associated with the remaining performance obligations over the next 40 months.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital. Forfeitures are recognized as they occur.

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized against deferred tax assets if it is more likely than not that such assets will not be realized in future years. Tax benefits for uncertain tax positions are recognized when it is more likely than not that the positions will be sustained upon examination based on their technical merits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statements of Operations. All tax effects related to share-based payments are recorded in the provision for income taxes in the periods during which the awards are exercised or vest.

Business Combinations, Goodwill and Intangible Assets

Business combinations are accounted for under the purchase method of accounting. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed requires judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, revenue growth rates, customer attrition rates, royalty rates, obsolescence and asset lives. Intangible assets are valued using various methodologies, including the relief-from-royalty method and multi-period excess earnings method.

The Company operates as a single reporting unit. Following an acquisition, goodwill no longer retains its identification with a particular acquisition, but instead becomes identifiable with the entire reporting unit. As a result, all of the fair value of the Company is available to support the value of goodwill. An impairment review of goodwill is performed on an annual basis, at year-end, or more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives which range from one to 15 years using either a straight-line or accelerated amortization method based on the pattern of economic benefit the Company expects to realize from such assets. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.

Equity Investments and Consolidation

The Company evaluates equity investments for potential consolidation under the voting-interest or variable-interest models. The Company consolidates investees over which the Company determines it has control under the voting interest model, generally greater than 50% ownership, or for which the Company is the primary beneficiary under the variable-interest model. The Company uses the equity method of accounting when it exercises significant influence over the investee, but does not have operating control, generally between 20% and 50% ownership. Under the equity method of accounting, original investments are recorded at cost in prepaid expenses and other assets on the Consolidated Statements of Financial Condition and adjusted by the Company’s proportionate share of the investees’ undistributed earnings or losses. Equity investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average shares outstanding of common stock reflects the dilutive effect that could occur if convertible securities or other contracts to issue common stock were converted into or exercised for common stock.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation and income taxes paid. The ASU is effective for the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The guidance may be applied on a prospective or retrospective basis and early adoption is permitted. Adoption of this ASU will result in additional disclosures, but will not have an impact on the Company’s consolidated statements of financial condition, operations and cash flows.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The ASU primarily will require enhanced disclosures about certain types of expenses. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, and may be applied either on a prospective or retrospective basis. The Company is currently evaluating the impact of the standard on its disclosures.

Money market funds are included in cash and cash equivalents on the Consolidated Statements of Financial Condition. Securities available-for-sale and trading securities are included in investments, at fair value on the Consolidated Statements of Financial Condition. Securities classified within Level 2 were valued using a market approach utilizing prices and other relevant information generated by market transactions involving comparable assets. The foreign currency forward contracts are included in either other assets or accounts payable, accrued expenses and other liabilities on the Consolidated Statements of Financial Condition, and are classified within Level 2 as the valuation inputs are based on quoted market prices. The mutual funds held in a rabbi trust represent investments associated with the Company’s deferred cash incentive plan.

During each of the six months ended June 30, 2025 and 2024, there were no transfers of securities between Level 1, Level 2 and Level 3.

 

The table below presents the carrying value, fair value and fair value hierarchy category of the Company’s financial assets and liabilities that are not measured at fair value on the Consolidated Statements of Financial Condition. The carrying values of the Company’s financial assets and liabilities not measured at fair value categorized in the fair value hierarchy as Level 1 and Level 2 approximate fair value due to the short-term nature of the underlying assets and liabilities.

6. Acquisitions and Equity Investments

RFQ Hub Holdings LLC Acquisition

In May 2022, the Company acquired a minority ownership stake in RFQ–hub Holdings LLC (“RFQ-hub”), an entity formed with a consortium of market participants to support the growth of a multi-asset request for quote platform. In April 2024, the Company entered into a Unit Purchase Agreement with Virtu Financial Operating LLC and RFQ-hub to purchase a controlling stake of RFQ–hub (the “2025 RFQ-hub Acquisition”). The 2025 RFQ-hub Acquisition was completed on May 9, 2025 (the “Acquisition Date”).

Between May 2022 and the Acquisition Date, the Company possessed significant influence over RFQ–hub and accounted for its investment under the equity method of accounting. The Company’s investment was recorded at carrying value within prepaid expenses and other assets on the Consolidated Statements of Financial Condition and the Company’s proportionate share of RFQ–hub’s net earnings was recorded within equity in earnings of unconsolidated affiliate on the Consolidated Statements of Operations.

Following the Acquisition Date, the Company holds a 90.3% controlling stake in RFQ-hub, subject to the call and put rights and incentive agreements described below under “−Redeemable Noncontrolling Interest.” The 2025 RFQ-hub Acquisition is being accounted for as a business combination under ASC 805, Business Combinations. The 2025 RFQ-hub Acquisition cash consideration totaled $38.1 million.

The Company has performed a preliminary valuation analysis of the fair market values of its previously-held interests in RFQ-hub and of the assets and liabilities of RFQ-hub and its wholly-owned subsidiaries. The final purchase price allocation will be determined when the Company has completed its evaluation of the valuation analysis. The final allocation could differ materially from the preliminary allocation and may include changes in (i) allocations to acquired intangible assets; (ii) goodwill; (iii) redeemable noncontrolling interest; and (iv) other assets and liabilities. The Company expects to finalize the valuation and complete the accounting for the business combination as soon as practicable, but no later than one year from the Acquisition Date. Measurement period adjustments, if any, will be recognized in the reporting period in which the adjustment amounts are determined.

The following table sets forth the components and the allocation of the purchase price for the business combination and summarizes the preliminary fair values of the assets acquired and liabilities assumed at the Acquisition Date:

RFQ-hub’s assets and liabilities were measured at estimated fair values on the Acquisition Date. Estimates of fair value represent management’s best estimate and require significant judgment about future events and uncertainties. Third-party valuation specialists were engaged to assist in the valuation of these assets and liabilities. The redeemable noncontrolling interests were valued using an option pricing model. The acquired developed technology and customer relationships intangible assets were valued using the relief-from-royalty method and multi-period excess earnings method, respectively. The fair values of the intangible assets acquired are as follows:

The goodwill recognized in connection with the 2025 RFQ-hub Acquisition is primarily attributable to the acquisition of an assembled workforce and expected future technology and synergies from the integration of the operations of RFQ-hub into the Company's operations. Approximately $19.5 million of the goodwill recognized in connection with the 2025 RFQ-hub Acquisition is expected to be deductible for income tax purposes.

Pro forma financial information and current period results for the 2025 RFQ-hub Acquisition were not material to the Company’s consolidated financial statements and therefore have not been presented.

Redeemable Noncontrolling Interest

The Second Amended and Restated Limited Liability Company Agreement of RFQ-Hub Holdings LLC (the “RFQ-hub LLC Agreement”) contains a call right under which the Company may, during certain pre-set periods, require the noncontrolling equity holders of RFQ-hub to sell their interest to the Company at the fair market value of RFQ-hub as determined at the time this right is exercised (the “Call Right”). The RFQ-hub LLC Agreement also contains a put right under which the noncontrolling equity holders may, during certain periods after expiration of the availability of the Call Right, require the Company to purchase their interests at the fair market value of RFQ-hub as determined at the time this right is exercised. The redeemable noncontrolling interest is classified as temporary equity on the Consolidated Statements of Financial Condition and is recorded at fair value.

In addition, pursuant to certain incentive agreements, the Company and the noncontrolling equity holders of RFQ-hub may earn additional equity interests in RFQ-hub based on certain performance metrics. The Company records expense for the additional equity interests earned by the noncontrolling equity holders based on the fair market value of these equity units as of the Acquisition Date. The expense recorded by the Company for the three months ended June 30, 2025 was $0.9 million and is included within other, net on the Consolidated Statements of Operations, with a corresponding increase to redeemable noncontrolling interest.

The provision for income taxes was $26.2 million and $21.4 million for the three months ended June 30, 2025 and 2024, respectively, and $107.3 million and $45.5 million for the six months ended June 30, 2025 and 2024, respectively. The Company’s effective tax rate was 26.9% and 24.8% for the three months ended June 30, 2025 and 2024, respectively, and 55.4% and 24.9% for the six months ended June 30, 2025 and 2024, respectively. The Company’s effective tax rate can vary from period to period depending on the geographic mix of our earnings, changes in tax legislation and tax rates, changes in unrecognized tax benefits and the amount and timing of excess tax benefits related to stock-based payments, among other factors. The provision for income taxes includes provisions for unrecognized tax benefits of $2.5 million and $58.8 million for the three and six months ended June 30, 2025, respectively. As of June 30, 2025, the Company’s liability for unrecognized tax benefits was $58.8 million.

The Company or one of its subsidiaries files U.S. federal, state and foreign income tax returns. The Company is currently under a New York State income tax examination for tax years 2015 through 2020 and a New York City income tax examination for the tax years 2016 through 2018. At this time, the Company cannot estimate when the examinations will conclude or the impact such examinations will have on the Company’s Consolidated Financial Statements, if any. Generally, other than the New York City and New York State audits, the Company is no longer subject to tax examinations by tax authorities for years prior to 2020.

Credit Agreements and Short-term Financing

11. Credit Agreements and Short-term Financing

Credit Agreement

On August 9, 2023, the Company entered into a three-year revolving credit facility (the “Credit Agreement”) provided by a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent, which provides aggregate commitments totaling $750.0 million, including a revolving credit facility, a $5.0 million letter of credit sub-limit for standby letters of credit and a $380.0 million sub-limit for swingline loans. The Credit Agreement will mature on August 9, 2026, with the Company’s option to request up to two additional 364-day extensions at the discretion of each lender and subject to customary conditions. Subject to satisfaction of certain specified conditions, the Company is permitted to upsize the Credit Agreement by up to $375.0 million in total. As of June 30, 2025, the Company had $0.1 million in letters of credit outstanding and $749.9 million in available borrowing capacity under the Credit Agreement.

Borrowings under the Credit Agreement will bear interest at a rate per annum equal to an alternate base rate or the adjusted term Secured Overnight Financing Rate (“SOFR”) rate, plus an applicable margin that varies with the Company’s consolidated total leverage ratio. The Credit Agreement requires that the Company satisfy certain covenants, including a requirement not to exceed a maximum consolidated total leverage ratio. The Company incurred no interest expense under the Credit Agreement for the three and six months ended June 30, 2025. The Company incurred $0.2 million of interest expense under the Credit Agreement for the three and six months ended June 30, 2024.

Uncommitted Collateralized Agreements

In connection with their self-clearing operations, certain of the Company’s U.S. and U.K. operating subsidiaries maintain agreements with a settlement bank to allow the subsidiaries to borrow in the aggregate of up to $500.0 million on an uncommitted basis, collateralized by eligible securities pledged by the subsidiaries to the settlement bank, subject to certain haircuts. Borrowings under these agreements will bear interest at a base rate per annum equal to the higher of the upper range of the Federal Funds Rate, 0.25% or one-month SOFR, plus 1.00%.

The Company incurred no interest expense on borrowings under such agreements during each of the three and six months ended June 30, 2025 and 2024. As of June 30, 2025, the Company had no borrowings outstanding and up to $500.0 million in available uncommitted borrowing capacity under such agreements.

Short-term Financing

Under arrangements with their settlement banks, certain of the Company’s U.S. and U.K. operating subsidiaries may receive overnight financing in the form of bank overdrafts. The Company incurred interest expense on such overnight financing of $0.1 million and $0.5 million during the three months ended June 30, 2025 and 2024, respectively, and $0.3 million and $0.8 million during the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025, the Company had no overdrafts payable outstanding.

12. Leases

The Company has operating leases for corporate offices with initial lease terms ranging from one year to 15 years. Certain leases contain options to extend the initial term at the Company’s discretion. The Company accounts for the option to extend when it is reasonably certain of being exercised. The Company’s lease agreements do not contain any material residual value guarantees, restrictions or covenants. The Company also has operating and finance leases for equipment with initial lease terms ranging from one-year to 5 years.

Finance lease expense was $0.1 million for each of the three and six months ended June 30, 2025 and 2024.

The Company determines whether an arrangement is, or includes, a lease at contract inception. Operating lease right-of-use assets and liabilities are recognized at commencement date and are initially measured based on the present value of lease payments over the defined lease term. As the Company’s leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at the adoption date in determining the present value of lease payments.

The weighted average remaining lease term and weighted average discount rate are as follows:

Commitments and Contingencies

13. Commitments and Contingencies

Legal

In the normal course of business, the Company and its subsidiaries included in the consolidated financial statements may be involved in various lawsuits, proceedings and regulatory examinations. The Company assesses its liabilities and contingencies in connection with outstanding legal proceedings, if any, utilizing the latest information available. For matters where it is probable that the Company will incur a material loss and the amount can be reasonably estimated, the Company will establish an accrual for the loss. Once established, the accrual will be adjusted to reflect any relevant developments. When a loss contingency is not both probable and estimable, the Company does not establish an accrual.

Based on currently available information, the outcome of the Company’s outstanding matters is not expected to have a material adverse impact on the Company’s financial position. It is not presently possible to determine the ultimate exposure to these matters, and there is no assurance that the resolution of the outstanding matters will not significantly exceed any reserves accrued by the Company.

Other

The Company, through certain of its subsidiaries, executes securities transactions between its institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller in trades. The Company’s operating subsidiaries settle such transactions pursuant to their self-clearing operations or through the use of third-party clearing brokers or settlement agents. Settlement typically occurs within one to two trading days after the trade date. Cash settlement of the transaction occurs upon receipt or delivery of the underlying instrument that was traded. Under both the self-clearing and the third-party clearing models, the Company may be exposed to credit risk in the event a counterparty does not fulfill its obligation to complete a transaction or if there is an error in executing a matched principal transaction. Pursuant to the terms of the securities clearing agreements, each third-party clearing broker has the right to charge the Company for any losses they suffer resulting from a counterparty’s failure on any of the Company’s trades. The Company did not record any liabilities or losses with regard to counterparty failures for the six months ended June 30, 2025 and 2024.

In the normal course of business, the Company enters into contracts that contain a variety of representations, warranties and indemnification provisions. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, based on experience, the Company expects the risk of loss to be remote.

In January 2022, the Board of Directors authorized a share repurchase program for up to $150.0 million (the “2022 Repurchase Program”). In August 2024, the Board of Directors authorized a share repurchase program for up to an additional $200.0 million (the “2024 Repurchase Program” and, together with the 2022 Repurchase Program, the “Repurchase Programs”). The Repurchase Programs do not have an expiration date. During the six months ended June 30, 2025, the Company repurchased 355,688 shares of common stock under the Repurchase Programs at a cost of $74.8 million. The 2022 Repurchase Plan was exhausted during the first quarter of 2025 and, as of June 30, 2025, the Company had $150.3 million of remaining capacity under the 2024 Repurchase Program. Shares repurchased under the Repurchase Programs will be held in treasury for future use.

Segment Reporting [Abstract]  
Segment and Geographic Information

15. Segment and Geographic Information

The Company’s end-to-end trading solutions comprise one reportable segment. The Company’s end-to-end trading solutions segment includes the operation of electronic platforms for the trading of fixed-income and other securities and related data, analytics, compliance tools, post-trade services and technology services. The Company derives revenue primarily in North America and Europe and manages its business activities on a consolidated basis. The Company considers its operations to constitute a single business segment due to the highly integrated nature of these products and services within the trading lifecycle, the use of a single inter-connected suite of technology solutions underlying all services, the financial markets in which the Company competes and the Company’s worldwide business activities.

The accounting policies of the Company’s reportable segment are the same as those described in the summary of significant accounting policies. The Company’s chief operating decision maker (“CODM”) assesses performance of the Company overall and decides how to allocate resources based on net income that is reported on the consolidated statement of operations as net income. The measure of segment assets is reported on the consolidated statement of financial condition as total assets. The Company’s CODM is its Chief Executive Officer. The CODM uses net income to evaluate income generated from segment assets in deciding whether to reinvest profits into the Company’s end-to-end trading solutions or into other areas, such as for acquisitions or to pay dividends. Net income is used to monitor budget versus actual results. The significant segment expenses and net income reviewed by the CODM conform to the presentation of such items in the consolidated statements of operations.

For the three and six months ended June 30, 2025 and 2024, the U.K. was the only individual foreign country in which the Company had operations that accounted for 10.0% or more of total revenues or total long-lived assets. Revenues and long-lived assets are attributed to a geographic area based on the location of the client trading activity and receipt of services. Long-lived assets are defined as furniture, equipment, leasehold improvements and capitalized software. Revenues for the three and six months ended June 30, 2025 and 2024, and long-lived assets as of June 30, 2025 and December 31, 2024 were as follows:

Accounting Policies [Abstract]  
Basis of Presentation

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated. These consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The consolidated financial information as of December 31, 2024 has been derived from audited financial statements not included herein. These unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) with respect to Form 10-Q and reflect all adjustments that, in the opinion of management, are normal and recurring, and that are necessary for a fair statement of the results for the interim periods presented. In accordance with such rules and regulations, certain disclosures that are normally included in annual financial statements have been omitted. Interim period operating results may not be indicative of the operating results for a full year.
Cash and Cash Equivalents

Cash and Cash Equivalents

The Company defines cash equivalents as short-term interest-bearing investments with maturities at the time of purchase of three months or less.
Investments

Investments

The Company determines the appropriate classification of securities at the time of purchase which are recorded in the Consolidated Statements of Financial Condition on the trade date. Securities are classified as available-for-sale or trading. Available-for-sale investments are carried at fair value with unrealized gains or losses reported in accumulated other comprehensive loss in the Consolidated Statements of Financial Condition and realized gains or losses reported in other, net in the Consolidated Statements of Operations. Trading investments include U.S. Treasuries and are carried at fair value, with realized and unrealized gains or losses included in other, net in the Consolidated Statements of Operations.

The Company assesses whether an impairment loss on its available-for-sale debt securities has occurred due to declines in fair value or other market conditions. When the amortized cost basis of an available-for-sale debt security exceeds its fair value, the security is deemed to be impaired. The portion of an impairment related to credit losses is determined by comparing the present value of cash flows expected to be collected from the security with the amortized cost basis of the security and is recorded as a charge in the Consolidated Statements of Operations. The remainder of an impairment is recognized in accumulated other comprehensive loss if the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security prior to recovery.
Fair Value Financial Instruments

Fair Value Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” A three-tiered hierarchy for determining fair value has been established that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as Level 1 (unadjusted quoted prices for identical assets or liabilities in active markets), Level 2 (inputs that are observable in the marketplace other than those inputs classified in Level 1) and Level 3 (inputs that are unobservable in the marketplace). The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of its money market funds, trading securities, available-for-sale securities and foreign currency forward contracts. All other financial instruments are short-term in nature and the carrying amounts reported on the Consolidated Statements of Financial Condition approximate fair value.
Receivables from and Payables to Broker - dealers, Clearing Organizations and Customers

Receivables from and Payables to Broker-dealers, Clearing Organizations and Customers

Receivables from broker-dealers, clearing organizations and customers include amounts receivable for securities not delivered by the Company to the purchaser by the settlement date (“securities failed-to-deliver”) and cash deposits held at clearing organizations and clearing brokers to facilitate the settlement and clearance of matched principal transactions. Payables to broker-dealers, clearing organizations and customers include amounts payable for securities not received by the Company from a seller by the settlement date (“securities failed-to-receive”). Securities failed-to-deliver and securities failed-to-receive for transactions executed on a matched principal basis where the Company serves as a counterparty to both the buyer and the seller are recorded on a settlement date basis. The Company presents its securities failed-to-deliver and securities failed-to-receive balances on a net-by-counterparty basis within receivables from and payables to broker-dealers, clearing organizations and customers. The difference between the Company’s trade-date receivables and payables for unsettled matched principal transactions reflects commissions earned and is recorded within accounts receivable, net on a trade date basis.

All accounts receivable have contractual maturities of less than one year and are derived from trading-related fees and commissions and revenues from products and services. The Company continually monitors collections and payments from its customers and maintains an allowance for doubtful accounts. The allowance for credit losses is based on the estimated expected credit losses in accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific collection issues that have been identified. Account balances are grouped for evaluation based on various risk characteristics, including billing type, legal entity, and geographic region. Additions to the allowance for credit losses are charged to bad debt expense, which is included in general and administrative expense in the Company’s Consolidated Statements of Operations. Balances that are determined to be uncollectable are written off against the allowance for credit losses.

The allowance for credit losses was $0.5 million and $1.0 million as of June 30, 2025 and December 31, 2024, respectively. The provision for bad debts and write-offs and other charges against the allowance for credit losses were immaterial for the three and six months ended June 30, 2025 and 2024, respectively.
Depreciation and Amortization

Depreciation and Amortization

Fixed assets are carried at cost less accumulated depreciation. The Company uses the straight-line method of depreciation over three to seven years. The Company amortizes leasehold improvements on a straight-line basis over the lesser of the life of the improvement or the remaining term of the lease.
Software Development Costs

Software Development Costs

The Company capitalizes certain costs associated with the development of internal use software, including, among other items, employee compensation and related benefits and third-party consulting costs at the point at which the conceptual formulation, design and testing of possible software project alternatives have been completed. Once the product is ready for its intended use, such costs are amortized on a straight-line basis over three to five years. The Company reviews the amounts capitalized for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable.
Foreign Currency Translation and Forward Contracts

Foreign Currency Translation and Forward Contracts

Assets and liabilities denominated in foreign currencies are translated using exchange rates at the end of the period; revenues and expenses are translated at average monthly rates. Gains and losses on foreign currency translation are a component of accumulated other comprehensive loss in the Consolidated Statements of Financial Condition. Transaction gains and losses are recorded in other, net in the Consolidated Statements of Operations.

The Company enters into foreign currency forward contracts to economically hedge its foreign currency transaction gains and losses. Realized and unrealized gains and losses on these forward contracts are included in other, net in the Consolidated Statements of Operations. The Company records the fair value of the forward contract asset in prepaid expenses and other assets or the fair value of the forward contract liability in accounts payable, accrued expenses and other liabilities in the Consolidated Statements of Financial Condition.

Revenue Recognition

Revenue Recognition

The Company’s classification of revenues in the Consolidated Statements of Operations represents revenues from contracts with customers disaggregated by type of revenue. The Company has four revenue streams as described below.

Commission Revenue – The Company charges its broker-dealer clients variable transaction fees for trades executed on its platforms and, under certain plans, distribution fees or monthly minimum fees to use the platforms for a particular product area. Variable transaction fees are recognized on a trade date basis, are generally calculated as a percentage of the notional dollar volume of bonds traded on the platforms and vary based on the type, size, yield and maturity of the bond traded, as well as individual client incentives. Bonds that are more actively traded or that have shorter maturities generally generate lower commissions, while bonds that are less actively traded or that have longer maturities generally command higher commissions. Under the Company’s disclosed trading transaction fee plans, variable transaction fees, distribution fees and unused monthly fee commitments are invoiced and recorded on a monthly basis.

For Open Trading trades that the Company executes between and among institutional investor and broker-dealer clients on a matched principal basis by serving as counterparty to both the buyer and the seller, the Company earns its commission through the difference in price between the two trades. The commission is collected upon settlement of the trade, which typically occurs within one to two trading days after the trade date. For the majority of the Company’s U.S. Treasury matched principal trades, commissions are invoiced and recorded on a monthly basis.

The Company also earns other commissions on equities and foreign exchange products for algorithmic trading services. These fees incorporate variable transaction fees, which are calculated as a percentage of the notional dollar volume traded and are billed on a monthly basis.

Information services – Information services includes data licensed to the Company’s broker-dealer clients, institutional investor clients and data-only subscribers; professional and consulting services; technology software licenses; and maintenance and support services. The nature and timing of each performance obligation may vary as these contracts are either subscription-based services transferred over time, and may be net of volume-based discounts, or one-time services that are transferred at a point in time. Revenues for services transferred over time are recognized ratably over the contract period as the Company’s performance obligation is met, whereas revenues for services transferred at a point in time are recognized in the period the services are provided. Customers are generally billed monthly, quarterly, or annually; revenues billed in advance are deferred and recognized ratably over the contract period.

Post-trade services – Post-trade services revenue is generated from regulatory transaction reporting, trade publication and post-trade matching services. Customers are generally billed monthly in arrears, and revenue is recognized in the period transactions are processed. Revenues billed in advance are deferred and recognized ratably over the contract period. The Company also generates one-time implementation fees for onboarding clients, which are invoiced and recognized in the period the implementation is completed.

The majority of the Company’s information services and post-trade services contracts are short-term in nature with durations of one year or less. For contracts with original durations extending beyond one year, the aggregate amount of the transaction price allocated to remaining performance obligations was $40.4 million as of June 30, 2025. The Company expects to recognize revenue associated with the remaining performance obligations over the next 40 months.
Stock-Based Compensation

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards based on their estimated fair values measured as of the grant date. These costs are recognized as an expense in the Consolidated Statements of Operations over the requisite service period, which is typically the vesting period, with an offsetting increase to additional paid-in capital. Forfeitures are recognized as they occur.

Income Taxes

Income Taxes

Income taxes are accounted for using the asset and liability method. Deferred income taxes reflect the net tax effects of temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when such differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recognized against deferred tax assets if it is more likely than not that such assets will not be realized in future years. Tax benefits for uncertain tax positions are recognized when it is more likely than not that the positions will be sustained upon examination based on their technical merits. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes in the Consolidated Statements of Operations. All tax effects related to share-based payments are recorded in the provision for income taxes in the periods during which the awards are exercised or vest.

Business Combinations, Goodwill and Intangible Assets

Business Combinations, Goodwill and Intangible Assets

Business combinations are accounted for under the purchase method of accounting. The total cost of an acquisition is allocated to the underlying net assets based on their respective estimated fair values. The excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Determining the fair value of certain assets acquired and liabilities assumed requires judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, revenue growth rates, customer attrition rates, royalty rates, obsolescence and asset lives. Intangible assets are valued using various methodologies, including the relief-from-royalty method and multi-period excess earnings method.

The Company operates as a single reporting unit. Following an acquisition, goodwill no longer retains its identification with a particular acquisition, but instead becomes identifiable with the entire reporting unit. As a result, all of the fair value of the Company is available to support the value of goodwill. An impairment review of goodwill is performed on an annual basis, at year-end, or more frequently if circumstances change. Intangible assets with definite lives, including purchased technologies, customer relationships and other intangible assets, are amortized over their estimated useful lives which range from one to 15 years using either a straight-line or accelerated amortization method based on the pattern of economic benefit the Company expects to realize from such assets. Intangible assets are assessed for impairment when events or circumstances indicate the existence of a possible impairment.
Equity Investments and Consolidation

Equity Investments and Consolidation

The Company evaluates equity investments for potential consolidation under the voting-interest or variable-interest models. The Company consolidates investees over which the Company determines it has control under the voting interest model, generally greater than 50% ownership, or for which the Company is the primary beneficiary under the variable-interest model. The Company uses the equity method of accounting when it exercises significant influence over the investee, but does not have operating control, generally between 20% and 50% ownership. Under the equity method of accounting, original investments are recorded at cost in prepaid expenses and other assets on the Consolidated Statements of Financial Condition and adjusted by the Company’s proportionate share of the investees’ undistributed earnings or losses. Equity investments are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable.

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing the net income attributable to common stock by the weighted-average number of shares of common stock outstanding during the period. For purposes of computing diluted earnings per share, the weighted-average shares outstanding of common stock reflects the dilutive effect that could occur if convertible securities or other contracts to issue common stock were converted into or exercised for common stock.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU requires disaggregated information about a reporting entity’s effective tax rate reconciliation and income taxes paid. The ASU is effective for the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The guidance may be applied on a prospective or retrospective basis and early adoption is permitted. Adoption of this ASU will result in additional disclosures, but will not have an impact on the Company’s consolidated statements of financial condition, operations and cash flows.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The ASU primarily will require enhanced disclosures about certain types of expenses. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, and may be applied either on a prospective or retrospective basis. The Company is currently evaluating the impact of the standard on its disclosures.
