Second Consecutive Month of Record Total Trading ADV on Continued Strong Market Volumes

NEW YORK--(BUSINESS WIRE)--MarketAxess Holdings Inc. (Nasdaq: MKTX), the operator of a leading electronic trading platform for fixed-income securities, today announced trading volume and preliminary variable transaction fees per million ("FPM") for October 2024.1

Chris Concannon, CEO of MarketAxess, commented:

"We delivered the second straight month of record total trading ADV in October, driven by continued robust market volumes and strength in our international businesses. Our rates business also generated record ADV in October, surpassing the previous monthly record set during a period of extreme market volatility in March 2020.

While we are disappointed with the absolute level of market share in U.S. high-grade in October, we were pleased to see record trading volumes, an increase in U.S. high-yield estimated market share compared to September and an increase in our preliminary total credit fee capture during the month. Most importantly, our preliminary total credit variable commission revenue in October was slightly above September levels. We believe the decline in our high-grade market share was driven by lower portfolio trading and a client shift to large block trading in the market. Large portfolio trades in the market and the mix of activity across U.S. high-grade TRACE can generate significant swings in market share without materially impacting revenue generation.

We are continuing the roll-out of X-Pro to our global client base and we now have our block solution in the market, which we believe will be integral to the success of our "high-touch" strategy."

General Notes Regarding the Data Presented

Reported MarketAxess volume in all product categories includes only fully electronic trading volume. MarketAxess trading volumes and the Financial Industry Regulatory Authority ("FINRA") Trade Reporting and Compliance Engine ("TRACE") reported volumes are available on the Company's website at investor.marketaxess.com/volume.

For periods beginning with January 2024, the Company has made changes to the market volume data used to calculate estimated market share for Municipal and U.S. Government Bonds. For Municipal Bonds, the Company previously used estimates, derived from data issued by the Municipal Securities Rule Making Board ("MSRB"), including estimates for new issuance, commercial paper and variable-rate trading activity, and excluded these volumes from the estimated market volume data. While the Company still uses estimates, the new methodology for identifying and excluding these volumes from the market volume data is now based on MSRB "flags" to identify new issuance, commercial paper, and variable-rate volumes. For U.S. Government Bonds, the previous data source for estimated market volumes was the Federal Reserve Bank's Reported Primary Dealer U.S. Treasury Bond Trading Volumes, which was reported on a one-week lag. The new source for U.S. Government Bond trading volumes is FINRA's U.S. Treasury TRACE data. The Company believes that the refined methodology used for Municipal Bonds, and the new data source for U.S. Government Bonds, provides more accurate measures of estimated market volumes and estimated market share. Prior comparable periods have been recast retrospectively for both Municipal and U.S. Government Bonds to conform to the updated presentation of the data. The new estimated market volume data is also available on the Company's website at investor.marketaxess.com/volume.
