Adoption of MarketAxess X-Pro, our new trading platform, continues to grow. We are seeing early signs that our unique proprietary data is enhancing the client experience on our platforms, including the execution of portfolio trades. Additionally, we just completed the acquisition of Pragma, which we expect to accelerate our automation and client algo strategies.   We believe that the progress we have made in enhancing the franchise over the past few years has set the foundation for a return to stronger levels of growth in the coming quarters.”

3Q23 overview of results

Revenues and trading volume

Credit

• Total credit commission revenue of $145.2 million (including $36.2 million in fixed-distribution fees) decreased $2.4 million, or 2%, compared to $147.6 million (including $31.3 million in fixed-distribution fees) in the prior year. The decrease in total credit commission revenue was driven principally by lower estimated market share and lower average fee per million (“FPM”), partially offset by a $4.8 million, or 15%, increase in total credit fixed-distribution fees. The increase in total credit fixed-distribution fees was driven principally by new dealers on fixed fee plans and upgrades of dealers on existing fixed fee plans. The decline in FPM for total credit to $154.85 from $165.60 in the third quarter of 2022 was mainly due to product mix-shift in other credit products, primarily lower U.S. high-yield activity and the lower duration of bonds traded in U.S. high-grade.

• The last week of September 2023 was the second highest week of credit trading volume ever for the Company, as volatility increased at the end of the month.

• U.S. high-grade ADV of $5.2 billion, up 1.1% with estimated market share of 20.0%. U.S. high-grade estimated market ADV increased 6.4%.

• U.S. high-yield ADV of $1.3 billion, down 20.4% with estimated market share of 16.1%. U.S. high-yield estimated market ADV decreased 4.5%. The decrease in U.S. high-yield estimated market share was driven principally by low levels of credit spread volatility, resulting in a decrease in ETF market maker activity on the platform. The VIX index, an indicator of volatility, was an average 15.1 in 3Q23, down 39.1% from 24.7 in 3Q22.

• 8.0% increase in emerging markets ADV to $2.8 billion, driven by a 26.9% increase in local markets trading volume, partially offset by a 4.2% decline in hard currency trading volume; 4.3% decrease in emerging markets estimated market ADV.⁷

• 18.2% increase in Eurobonds ADV to $1.5 billion. Eurobonds estimated market ADV increased 31.6%.⁵

• Municipal bond ADV of $388 million, up 7.4% with estimated market share of 5.8%. Municipal bond estimated market ADV decreased 10.1%.

• $27.5 billion in total portfolio trading volume, up 11.1% from $24.7 billion in 3Q22.

• 33% Open Trading^® share¹ of total credit trading volume, down from 37% in the prior year on lower credit spread volatility. Estimated price improvement² delivered via Open Trading in the quarter was approximately $120 million and is $529 million year-to-date through September 2023.

Rates

• Total rates commission revenue of $5.2 million decreased 5% compared to the prior year, mainly due to the 11% decrease in rates ADV to $18.1 billion, which was partially offset by a 9% increase in FPM for total rates products to $4.56, compared to $4.17 in the third quarter of 2022.

• 289 active client firms on the platform, up 40% from 206 in the prior year.

Information services & post-trade services

• Record information services revenue of $11.8 million increased $2.1 million, or 22%, compared to the prior year. The increase in revenue was principally driven by new Composite+ data contract revenue and the impact of foreign currency fluctuations. Excluding the impact of foreign currency fluctuations, information services revenue would have increased approximately 17%.

• Post-trade services revenue of $9.8 million was up 9% compared to the prior year mainly due to the impact of foreign currency fluctuations. Excluding the impact of foreign currency fluctuations, post-trade services revenue would have increased approximately 2%.

Expenses

• Total expenses of $105.4 million increased $9.5 million, or 10%. The increase in expenses was driven principally by higher employee compensation and benefits as a result of a 17% increase in headcount, mainly in technology and customer-facing roles, higher depreciation and amortization expense and increased professional and consulting fees. Excluding the impact of foreign currency fluctuations, total expenses would have increased approximately 8%.

Non-operating

• Other income (expense): Other income was $4.8 million, up from $2.6 million in the prior year. The current quarter included interest income of $6.6 million, compared to $1.4 million in the prior year, driven by higher interest rates.

• Tax rate: The effective tax rate was 23.4%, compared to 24.8% in the prior year.

Capital

• The Company had $553.3 million in cash, cash equivalents and investments; there were no outstanding borrowings under the Company’s credit facility.

• The Board declared a quarterly cash dividend of $0.72 per share, payable on November 22, 2023 to stockholders of record as of the close of business on November 8, 2023.

Other

• Employee headcount was 853 as of September 30, 2023, compared to 732 as of September 30, 2022 and 803 as of June 30, 2023. The increase in headcount compared to the prior year was principally due to the continued investment in the Company’s growth initiatives, including geographic expansion, trading automation and new trading protocols.

Guidance

• Based on the progression of operating expenses and the acquisition of Pragma, which closed on October 2, 2023, the Company is refining its previously stated full-year 2023 expense guidance range of $418.0 million to $446.0 million, to a new range of $432.0 million to $438.0 million. The new range includes an estimated $12.5 million of M&A related expenses, including $8.5 million of direct operating expenses related to Pragma and $4.0 million of non-recurring M&A expenses.

• The Company is reconfirming its full-year 2023 capital expenditures guidance range of $52.0 million to $58.0 million.

• The Company now expects the full-year 2023 effective tax rate to be approximately 23.5%, below the previously stated range of 25.0% to 26.0%. The lower effective tax rate for the year is mainly driven by favorable apportionment in connection with state tax filings and other federal tax filing positions.

¹ Open Trading share of total credit trading volume is derived by taking total Open Trading volume across all credit products where Open Trading is offered and dividing by total credit trading volume across all credit products where Open Trading is offered.

² Estimated price improvement consists of estimated liquidity taker price improvement (defined as the difference between the winning price and the best disclosed dealer cover price) and estimated liquidity provider price improvement (defined as the difference between the winning price and then current Composite+ bid or offer level, offer if the provider is buying, bid if provider is selling) at the time of the inquiry.

³ EBITDA and EBITDA margin are non-GAAP financial measures. Refer to “Non-GAAP financial measures and other items” for a discussion of changes made to the calculation of EBITDA beginning in the first quarter of 2023.

⁴  The number of U.S. trading days is based on the SIFMA holiday recommendation calendar and the number of U.K. trading days is based primarily on the U.K. bank holiday schedule.

⁵  Eurobonds estimated market ADV is derived from MarketAxess TraX data for Eurobonds and covered bonds market trading volume, which is now estimated to represent approximately 80% of the total European market beginning in September 2023, up from the previous estimate of 70%.

⁶ Composite corporate bond estimated market share is defined as combined estimated market share across U.S. high-grade (derived from FINRA TRACE reported data), U.S. high-yield (derived from FINRA TRACE reported data), emerging markets (derived from FINRA TRACE-reportable emerging markets volume, principally U.S. dollar denominated corporates) and Eurobonds (derived from MarketAxess TraX data, which is now estimated to represent approximately 80% of the total European market, up from the previous estimate of 70%) product areas.

⁷ Emerging markets estimated market ADV is derived by combining MarketAxess TraX emerging markets trading volume (estimated to represent approximately 60% of the total emerging markets market beginning in September 2023, up from the previous estimate of 55%) and FINRA TRACE-reportable emerging markets trading volume, principally U.S. dollar denominated corporates.

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 measures of financial performance, including earnings before interest, taxes, depreciation and amortization (“EBITDA”), EBITDA margin and free cash flow. Starting with the first quarter of 2023, our calculation of EBITDA has been revised to adjust for interest income in addition to interest expense. In prior periods, we only adjusted for interest expense because interest income amounts were insignificant. Prior comparable periods have now been recast to conform to the current presentation. Likewise, starting with the first quarter of 2023, EBITDA margin is calculated by adjusting for interest income in addition to interest expense and prior comparable periods have been recast to conform to the current presentation. 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. 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. See the attached schedule for a reconciliation of GAAP net income to EBITDA, GAAP net income margin to EBITDA margin and GAAP net cash provided by/(used in) operating activities to free cash flow.

The Company also presents revenue and expense growth rates excluding the impact of foreign currency fluctuations. The Company believes that it is useful to provide investors with this framework that is also used by management to assess how our business performed excluding the effect of foreign currency fluctuations. To present this information, current and comparative prior period results for product areas reporting in currencies other than U.S. dollars are converted into U.S. dollars using the average exchange rates from the comparative period rather than the actual exchange rates in effect during the current period.

Please refer to Tables 6 and 7 for a reconciliation of these non-GAAP financial measures to their most directly comparable GAAP measures.
