Insights

Equity research analyst

MarketAxess delivered double‑digit revenue growth, higher margins and robust trading volumes in Q1 2026.

MarketAxess generated total revenue of $233.4 million, up 12% year over year, as both credit and rates trading volumes expanded. Operating income rose 14% to $100.9 million, and GAAP net income climbed to $78.1 million, helped by a much lower effective tax rate versus the prior year.

On a non‑GAAP basis excluding notable items, diluted EPS increased 20% to $2.25, with EBITDA of $121.7 million and an EBITDA margin of 52.1%. Credit commission revenue grew 9% to $183.8 million, supported by a 17% increase in total credit average daily volume, while rates commission revenue rose 29% to $9.0 million.

Capital returns remained meaningful: the company completed final settlement of a $300.0 million accelerated share repurchase and ended March 31, 2026 with $205.0 million remaining under repurchase authorizations. The Board declared a quarterly dividend of $0.78 per share, modestly higher than the prior year. Overall, the filing reflects solid operating momentum without fundamentally changing the investment thesis.

Key Terms

EBITDA, accelerated share repurchase, average daily volume, variable transaction fee per million, +2 more

6 terms

EBITDA financial

"EBITDA 3 | | | 122 | | | 95 | | | 107 | | | 28"

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.

accelerated share repurchase financial

"Final settlement of the previously disclosed $300.0 million ASR occurred on February 4, 2026"

An accelerated share repurchase is a deal where a company hires a bank to buy back a large block of its own stock immediately on the open market, with the bank later settling the exact number of shares over time. For investors it matters because the immediate reduction in shares outstanding can raise per‑share earnings and often supports the stock price, but it also uses company cash or borrowing and can change liquidity and future growth funding.

average daily volume financial

"Total credit ADV compared to the prior year, driven by growth in market volumes"

Average daily volume is the typical number of shares or contracts of a security traded each day, calculated by averaging daily trading amounts over a recent period. It matters to investors because it indicates how easy it is to buy or sell without moving the price—like traffic on a road: high volume is a busy freeway that lets many cars pass smoothly, while low volume can make large orders cause big price changes and higher costs.

variable transaction fee per million financial

"total credit variable transaction fee per million (“FPM”)"

A variable transaction fee per million is a charge that changes with the size or frequency of trades or transfers and is expressed as an amount for each one million units of currency handled. Think of it like a delivery charge that rises or falls depending on how much you ship: larger volumes may lower the fee per million, while smaller or riskier activity can raise it. Investors care because this fee directly affects trading costs, net returns and the profitability of high-volume strategies.

non-GAAP financial measures financial

"Results excluding notable items are non-GAAP financial measures."

Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

effective tax rate financial

"The effective tax rate was 24.8%, compared to 84.3% in the prior year."

The effective tax rate is the percentage of a company's profits that it pays in taxes. It shows how much of its earnings go to taxes after all deductions and credits are considered. For investors, it indicates how much of the company's income is taken by taxes, impacting overall profitability and financial health.

Credit

•Record total credit commission revenue of $183.8 million (including $33.4 million in fixed-distribution fees) increased $14.6 million, or 9%, compared to $169.1 million (including $33.3 million in fixed-distribution fees) in the prior year, and was up 11% from 4Q25 levels. A 17% increase in total credit ADV compared to the prior year, driven by growth in market volumes, was partially offset by a 5% decrease in total credit variable transaction fee per million (“FPM”). The 9% increase in total credit commission revenue was driven by a 21% increase in emerging markets and eurobonds commission revenue, reflecting continued product and geographic diversification. The decline in 1Q26 total credit FPM year-over-year was driven by protocol and product mix, partially offset by the higher duration of bonds traded in U.S. high-grade. The quarter-over-quarter decline was due principally to product mix.

Rates

•Record total rates commission revenue of $9.0 million increased $2.0 million, or 29%, compared to the prior year, and increased 33% from 4Q25 levels. The increase compared to the prior year was driven by a 16% increase in total rates ADV and an 11% increase in FPM.

Other

•Record total other commission revenue of $10.7 million increased $5.5 million, or 104%, compared to the prior year, driven by the inclusion of approximately $4.3 million from RFQ-hub, majority control of which was acquired in 2Q25.

Services revenue

•Record services revenue2 of $29.9 million increased $2.7 million, or 10%, compared to the prior year.

Information services

—Information services revenue of $14.4 million increased $1.5 million, or 12%, compared to the prior year. The increase was principally driven by net new contract revenue and an increase of $0.5 million from the impact of foreign currency fluctuations.

Post-trade services

—Post-trade services revenue of $11.6 million increased $0.5 million, or 5%, compared to the prior year principally due to an increase of $1.0 million from the impact of foreign currency fluctuations.

Technology services

—Total technology services revenue of $3.9 million increased $0.6 million, or 19%, compared to the prior year. The increase was driven by connectivity fees from RFQ-hub, majority control of which was acquired in 2Q25.

Expenses

•Total expenses of $132.5 million increased 10% from the prior year, including approximately $3.4 million of RFQ-hub expenses and an increase of $2.2 million from the impact of foreign currency fluctuations. Total expenses, excluding notable items,1 of $130.3 million increased 8% from the prior year.

Non-operating

•Other income (expense): Other income was $3.0 million, down from $7.8 million in the prior year. The decrease was driven by lower interest income due to a decrease in interest rates and higher interest expense due to borrowings on the Company’s credit facility that were used, along with cash on hand, to fund the ASR, partially offset by receipt of a tax credit.

•Tax rate: The effective tax rate was 24.8%, compared to 84.3% in the prior year. The effective tax rate excluding notable items1 in the prior year was 27.2%.

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.
