Filing Explained

The proposed ICE acquisition still depends on stockholder approval and other closing conditions.

The company reports a definitive agreement for Intercontinental Exchange to acquire it, but the transaction remains proposed rather than completed: stockholder approval and other closing conditions are still outstanding, so no completed ownership transfer is disclosed.

Separately, the earnings release is furnished under Item 2.02 and is not treated as filed for Section 18 purposes or incorporated into other company filings unless specifically referenced.

5 terms

EBITDA financial

"including earnings before interest, taxes, depreciation and amortization (“EBITDA”), EBITDA margin"

EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's profitability by focusing on the money it makes from its core operations, ignoring expenses like taxes and accounting adjustments. Investors use EBITDA to compare how well different companies are performing financially, as it provides a clearer picture of operational success without the influence of financial structure or accounting choices.

free cash flow financial

"We define free cash flow as net cash provided by/(used in) operating activities"

Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

notable items financial

"Notable items are revenues, expenses, other income (expense) and tax related items"

Portfolio Trading ADV financial

"33% Increase in Portfolio Trading ADV to Record $2.0 Billion"

redeemable noncontrolling interest financial

"Redeemable noncontrolling interest | | | 14,441"

A redeemable noncontrolling interest is a minority ownership stake in a business that the minority owner can require to be bought back for cash or that must be redeemed under set conditions. Investors care because it is not permanent equity: it represents a foreseeable cash obligation and can reduce the parent company’s reported equity and available cash, much like a loan from a roommate you must repay on request rather than shared ownership of the house.

Credit

• Total credit commission revenue of $168.4 million (including $34.1 million in fixed-distribution fees) decreased $8.1 million, or 5%, compared to $176.6 million (including $33.6 million in fixed-distribution fees) in the prior year. Total credit ADV remained relatively flat compared with the prior year. The 5% decrease in total credit commission revenue was primarily driven by a 9% decrease in U.S. credit commission revenue, partially offset by growth in emerging markets and higher fixed distribution fees. The decline in 2Q26 total credit FPM year-over-year was driven by protocol and product mix, as well as lower duration of bonds traded in U.S. high-grade.

Rates

• Total rates commission revenue of $8.1 million was relatively flat compared to the prior year.

Other

• Total other commission revenue of $10.3 million increased $3.2 million, or 46%, compared to the prior year, primarily driven by the inclusion of RFQ-hub beginning in May 2025.

Services Revenue

• Record services revenue² of $31.5 million increased $3.8 million, or 14%, compared to the prior year.

Information Services

— Information services revenue of $16.1 million increased $3.0 million, or 23%, compared to the prior year. The increase was principally driven by net new contract revenue.

Post-trade Services

— Post-trade services revenue of $11.6 million increased $0.5 million, or 5%, compared to the prior year principally driven by net new contract revenue.

Technology Services

— Total technology services revenue of $3.8 million increased $0.3 million, or 8%, compared to the prior year principally driven by higher connectivity and licensing fees reflecting the inclusion of RFQ-hub.

Expenses

• Total expenses of $128.5 million increased 1% from the prior year. Total expenses, excluding notable items,¹ of $127.0 million increased 3% from the prior year.

Non-Operating

• Other Income (Expense): Other income was $(0.1) million, down from $5.6 million in the prior year. The decrease was largely driven by lower interest income resulting from lower average cash balances and lower yields driven by central bank rate cuts, higher interest expense mainly due to borrowings on the Company’s credit facility, along with cash on hand, to fund the accelerated stock repurchase agreement (the “ASR”) that settled in the first quarter of 2026, as well as foreign currency transaction losses in the current year as compared to foreign currency transaction gains in the prior year.

• Tax rate: The effective tax rate was 23.9%, compared to 26.9% in the prior year. The effective tax rate excluding notable items¹ was 24.5%, compared to 26.9% in the prior year.

• The Company had $404.8 million in cash, cash equivalents, corporate bond investments and U.S. Treasury investments as of June 30, 2026, down from $678.9 million as of December 31, 2025. The decline from year-end 2025 primarily reflects capital allocation activity during the first half of 2026, including cash used to pay down borrowings under the revolving credit facility, and quarterly dividend payments, in addition to an increase in net receivables from broker-dealers, clearing organizations and customers, partially offset by cash generated from operating activities. The Company had $112.0 million in borrowings outstanding under the Company’s credit facility as of June 30, 2026, as compared to $220.0 million in borrowings outstanding as of December 31, 2025.

¹ See Table 1A in this release for a listing of notable items. Results excluding notable items are non-GAAP financial measures. Refer to “Non-GAAP financial measures and other items” for a discussion of these non-GAAP financial measures and Table 6 for a reconciliation of these non-GAAP financial measures to their most directly comparable GAAP measures.

²  Services revenue is defined as combined information, post-trade and technology services revenue.

³ EBITDA and EBITDA margin are non-GAAP financial measures. Refer to “Non-GAAP financial measures and other items” for a discussion of these non-GAAP financial measures and Table 7 for a reconciliation of these non-GAAP financial measures to their most directly comparable GAAP measures.

Non-GAAP Financial Measures and Other Items

To supplement the Company’s unaudited financial statements presented in accordance with generally accepted accounting principles (“GAAP”), the Company uses certain non-GAAP financial measures, including earnings before interest, taxes, depreciation and amortization (“EBITDA”), EBITDA margin and free cash flow. From time to time, we present selected GAAP-basis financial results, excluding notable items. Notable items are revenues, expenses, other income (expense) and tax related items that are non-recurring and outside of the Company’s normal course of business or other notables, such as acquisition and restructuring charges or gains/losses on sales (collectively, “notable items”). We define EBITDA margin as EBITDA divided by revenues. We define free cash flow as net cash provided by/(used in) operating activities excluding the net change in trading investments and net change in securities failed-to-deliver and securities failed-to-receive from broker-dealers, clearing organizations and customers, less expenditures for furniture, equipment and leasehold improvements and capitalized software development costs. Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in conformity with GAAP. The Company believes that these non-GAAP financial measures, when taken into consideration with the corresponding GAAP financial measures, provide additional information regarding the Company’s operating results because they assist both investors and management in analyzing and evaluating the performance of our business. Please refer to Tables 6, 7 & 8 for a reconciliation of: (i) selected GAAP-basis financial results, each excluding notable items, to their most directly comparable GAAP measure; (ii) GAAP net income to EBITDA and GAAP net income margin to EBITDA margin; and (iii) GAAP net cash provided by/(used in) operating activities to free cash flow, in each case, the most directly comparable GAAP measure.

Forward-looking statements are inherently subject to certain risks, trends, changes in circumstances and uncertainties, many of which we cannot predict with accuracy and some of which we may not anticipate, including, but not limited to: historical financial information may not be representative of future results; the completion of the proposed transaction on the anticipated terms and timing, or at all, including obtaining the requisite approval by the stockholders of the Company, and the satisfaction of other conditions to the completion of the proposed transaction as well as the failure to realize anticipated benefits of the proposed transaction; there may be significant transaction costs in connection with the proposed transaction and the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; there may be liabilities that are not known, probable or estimable at this time or unexpected costs, charges or expenses; the occurrence of any event, change or other circumstance that could give rise to the termination of the proposed transaction, including in circumstances requiring the Company to pay a termination fee pursuant to the terms of the merger agreement; any effect of the announcement of the proposed transaction on the Company’s ability to operate its business and retain and hire key personnel and to maintain favorable business relationships; the proposed transaction may result in the diversion of management’s time and attention from ordinary course business operations to issues relating to the proposed transaction; certain restrictions during the pendency of the proposed transaction that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; unfavorable outcome of legal proceedings related to the proposed transaction; the risk that the Company’s share price may decline significantly if the proposed transaction is not consummated; legislative, regulatory and economic developments; unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism, outbreaks of war or hostilities or public health issues, as well as management’s response to any of the aforementioned factors; other risks and uncertainties detailed in periodic reports that the Company files with the SEC; actions by third parties, including government agencies; reputational risk and potential adverse reactions of the Company’s or ICE’s customers, employees or other business partners, including those resulting from the announcement or completion of the proposed transaction; the ability to promptly and effectively integrate the Company’s business with ICE’s business and realize the anticipated cost savings, synergies, and other financial benefits of the proposed transaction within the expected time period or at all; ICE’s ability to obtain the contemplated debt financing on a timely basis, on favorable terms or at all; global economic, political and market factors; the level of trading volume transacted on the MarketAxess platform; the rapidly evolving nature of the electronic financial services industry; the level and intensity of competition in the fixed-income electronic trading industry and the pricing pressures that may result; the variability of our growth rate; our ability to introduce new fee plans and our clients’ response; our ability to attract clients or adapt our technology and marketing strategy to new markets; risks related to our growing international operations; our dependence on our broker-dealer clients; the loss of any of our significant institutional investor clients; our exposure to risks resulting from non-performance by counterparties to transactions executed between our clients in which we act as an intermediary in matched principal trades; risks related to self-clearing; our dependence on third-party suppliers for key products and services; our ability to enter into strategic alliances and to acquire other businesses and successfully integrate them with our business; our dependence on our management team and our ability to attract and retain talent; risks related to sanctions levied against states or individuals that could expose us to operational or regulatory risks; the effects of climate change or other sustainability risks that could affect our operations or reputation; the effect of rapid market or technological changes on us and the users of our technology; issues related to the development and use of artificial intelligence; our ability to

successfully maintain the integrity of our trading platform and our response to system failures, capacity constraints and business interruptions; the occurrence of design defects, errors, failures or delays with our platforms, products or services; our vulnerability to malicious cyber-attacks and attempted cybersecurity breaches; our actual or perceived failure to comply with privacy and data protection laws; our ability to protect our intellectual property rights or technology and defend against intellectual property infringement or other claims; our use of open-source software; limitations on our flexibility because we operate in a highly regulated industry; the increasing government regulation of us and our clients; our exposure to costs and penalties related to our extensive regulation; our risks of litigation and securities laws liability; our tax filing positions; our future capital needs and our ability to obtain capital when needed; limitations on our operating flexibility contained in our credit agreement; our exposure to financial institutions by holding cash in excess of federally insured limits; and other factors.

There can be no assurance that the proposed transaction will be completed, or if it is completed, that it will close within the anticipated time period. While the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties and should be read in conjunction with the other forward-looking statements. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. The forward-looking statements relate only to events as of the date on which the statements are made and we undertake no obligation to update, and expressly disclaim any obligation to update, any forward-looking statements, or any other information in this communication, whether resulting from developments, circumstances or events that arise after the date the statements are made, new information, or otherwise. If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we may have expressed or implied by these forward-looking statements. All forward-looking statements in this communication are qualified in their entirety by this cautionary statement. You should specifically consider the factors identified in this communication that could cause actual results to differ. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

Although we believe that the expectations reflected in such forward-looking statements are based upon reasonable assumptions at the time made, we can give no assurance that such expectations will be achieved as anticipated or that our results, estimates or assumptions will be correct. Future events and actual results, financial and otherwise, may differ materially from the results discussed in the forward-looking statements, many of which are beyond the Company’s control. Readers are cautioned not to place undue reliance on these forward-looking statements and are advised to consider the factors listed above together with the additional factors under the heading “Disclosure Regarding Forward-Looking Statements” and “Risk Factors” in the Company’s Annual Report on Form 10-K, as may be supplemented or amended by the Company’s Quarterly Reports on Form 10-Q. The Company assumes no obligation to update or supplement forward-looking statements that become untrue because of subsequent events, new information or otherwise, except as required under applicable law. More information about these and other factors affecting MarketAxess’ business and prospects is contained in MarketAxess’ periodic filings with the Securities and Exchange Commission and can be accessed at www.marketaxess.com.
