MarketAxess (MKTX) grows 2025 revenue, ups buybacks and extends $750M credit line

Rhea-AI Filing Summary

MarketAxess Holdings Inc. renewed its funding and reported steady 2025 results. The company entered an amended and restated credit agreement preserving a $750.0 million revolving credit facility, extending maturity to February 2, 2029, with an option to request two additional 364‑day extensions and potential upsizing by up to $375.0 million. It has $220.0 million currently drawn. For 2025, revenue rose 4% to $846.3 million, while net income declined 10% to $246.9 million and diluted EPS was $6.64. Fourth‑quarter revenue was $209.4 million with net income of $92.4 million, helped by a $31.3 million tax reserve benefit. The board authorized additional buybacks and completed a $300.0 million accelerated share repurchase, buying 1,980,715 shares in 2025 at a cost of $360.0 million. A quarterly dividend of $0.78 per share will be paid on March 4, 2026 to holders of record on February 18, 2026. 2026 guidance calls for mid‑single‑digit services revenue growth, expenses excluding notable items of $530.0–$545.0 million, a 24–26% tax rate, and $65.0–$75.0 million of capital expenditures.

Insights

Equity and credit analyst

Stable growth, higher costs, more leverage and sustained capital returns.

MarketAxess delivered modest 2025 top-line growth with pressure on profitability. Revenue rose to $846.3 million (up 4%), but net income fell 10% to $246.9 million as expenses increased 6% to $504.4 million and EBITDA margin eased slightly.

Trading metrics were broadly healthy: total 2025 trading volume climbed 13% to $10.50 trillion, credit trading ADV increased 10%, and non‑U.S. products like emerging markets and eurobonds grew double‑digits. However, average credit variable fees per million declined 7%, indicating pricing or mix headwinds.

Capital allocation was active. The company used its credit facility, ending 2025 with $220.0 million of borrowings versus none a year earlier, and executed a $300.0 million ASR within a broader $400.0 million authorization, repurchasing about 1.98 million shares for $360.0 million. A quarterly dividend increase to $0.78 per share and 2026 guidance for mid‑single‑digit services growth and 8% expense growth (at guidance midpoint) suggest continued investment alongside ongoing shareholder returns.

Subject to satisfaction of certain specified conditions, the Company continues to be permitted to upsize the Credit Facility by up to $375.0 million in total.

As of the date hereof, the Company has $220.0 million in borrowings outstanding under the Credit Facility and one standby letter of credit, which borrowings were outstanding under the Existing Credit Agreement and remain outstanding under the A&R Credit Agreement.

Credit

•Total credit commission revenue of $165.2 million (including $32.8 million in fixed-distribution fees) increased $3.0 million, or 2%, compared to $162.2 million (including $32.8 million in fixed-distribution fees) in the prior year, and was consistent with 3Q25 levels. An 11% increase in total credit ADV compared to the prior year, driven by growth in market volumes, was partially offset by an 8% decrease in total credit variable transaction fee per million (“FPM”). The 2% increase in total credit commission revenue was driven by a 7% increase in emerging markets and eurobonds commission revenue, reflecting continued product and geographic diversification. The decline in 4Q25 total credit FPM both year-over-year and quarter-over-quarter was due principally to protocol mix.

Rates

•Total rates commission revenue of $6.8 million decreased $0.5 million, or 7%, compared to the prior year, and increased 2% from 3Q25 levels. A 17% decrease in total rates ADV compared to the prior year was partially offset by an 11% increase in FPM.

Other

•Record total other commission revenue of $9.4 million increased $4.1 million, or 79%, compared to the prior year, driven by the inclusion of approximately $3.4 million from RFQ-Hub, majority control of which was acquired in 2Q25.

Page 3

Services revenue

•Services revenue3 of $28.1 million increased $0.4 million, or 2%, compared to the prior year.

Information services

—Information services revenue of $13.5 million increased $0.3 million, or 2%, compared to the prior year. The increase was principally driven by an increase of $0.3 million from the impact of foreign currency fluctuations.

Post-trade services

—Post-trade services revenue of $11.0 million increased $0.1 million, or 1%, compared to the prior year principally due to an increase of $0.6 million from the impact of foreign currency fluctuations, partially offset by lower net contract revenue.

Technology services

—Total technology services revenue of $3.6 million increased $0.1 million, or 2%, 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 $133.4 million increased 9% from the prior year, including approximately $3.5 million of RFQ-hub expenses and an increase of $1.3 million from the impact of foreign currency fluctuations.

Non-operating

•Other income (expense): Other income was $3.8 million, down from $4.6 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 unrealized gains on investments compared to unrealized losses in the prior year.

•Tax rate: The effective tax rate was (15.8%), compared to 23.0% in the prior year. The effective tax rate excluding notable items1 was 23.4%.

Capital

•The Company had $678.9 million in cash, cash equivalents, corporate bond investments and U.S. Treasury investments as of December 31, 2025, down from $698.6 million as of December 31, 2024.

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 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.

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

4 The Company's guidance for full year 2026 is based on foreign exchange rates as of December 31, 2025, and assumes a constant business portfolio.

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. The Company does not reconcile its forward-looking non-GAAP financial measures, including the 2026 expense guidance, to the corresponding U.S. GAAP measures, due to variability and difficulty in making accurate forecasts and projections and/or certain information not being ascertainable or accessible; and because not all of the information, such as foreign currency impacts necessary for a quantitative reconciliation of these forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP financial measure, is available to the Company without unreasonable efforts. For the same reasons, the Company is unable to address the probable significance of the unavailable information. The Company provides forward-looking non-GAAP financial measures that it believes will be achieved, however, it cannot accurately predict all of the components of the adjusted calculations and the U.S. GAAP measures may be materially different than the non-GAAP measures.
