NEW YORK, February 6, 2008 — MarketAxess Holdings Inc. (Nasdaq: MKTX), the operator of a leading electronic trading platform for U.S. and European high-grade corporate bonds, emerging markets bonds and other types of fixed-income securities, today announced results for the fourth quarter and full year ended December 31, 2007.

Total revenues for the fourth quarter of 2007 increased 1.3% to $22.4 million, compared to $22.1 million for the fourth quarter of 2006. Pre-tax income for the fourth quarter of 2007 was $3.1 million, compared to $3.6 million for the fourth quarter of 2006, a decrease of 13.6%. Net income for the fourth quarter of 2007 totaled $1.9 million, or $0.06 per share on a diluted basis, compared to $2.2 million, or $0.06 per share on a diluted basis, for the fourth quarter of 2006.

For the fourth quarter of 2007, pre-tax margin was 13.9%, compared to 16.3% for the fourth quarter of 2006.

Richard M. McVey, chairman and chief executive officer of MarketAxess, commented, “While we were not immune to the unstable market environment during the fourth quarter of 2007, our business model performed well, driven by a solid base of fixed commission revenues, higher variable fees per million in our U.S. high grade business and strong recurring revenue generation from our information and data business. Free cash flow generation from our businesses continues to be strong and was in excess of two times net income for the full year 2007. Institutional investor demand for the MarketAxess system is robust, as the number of client trade inquiries submitted in our core U.S. high-grade product in the fourth quarter of 2007 was consistent with the number of inquiries submitted in the pre-market dislocation levels in the first and second quarters of 2007.”

Mr. McVey continued “We remain confident that the long-term trend toward higher market share for electronic trading in credit markets is intact, and we believe that we are well positioned for a return to more normal trading conditions.”

For the full year ended December 31, 2007, total revenue increased 12.4% to a record $93.6 million, from $83.3 million for the full year ended December 31, 2006. Pre-tax income for 2007 was a record

$17.3 million, compared to $8.6 million for 2006, an increase of 100.5%. Net income for 2007 was $10.3 million, or $0.30 per diluted share, compared to $5.4 million, or $0.15 per diluted share, for 2006.

For the full-year 2007, pre-tax margin was 18.4%, compared to 10.3% for 2006.

2007 Business Highlights

	•		Our estimated share of FINRA (Financial Industry Regulatory Authority) high-grade TRACE trading volume increased to 9.4% for 2007, compared to 8.5% for 2006, including a new record estimated quarterly share of 11.1% for the second quarter of 2007.

	•		We were awarded “Best Multi-Dealer Credit Default Swaps Trading Platform” and “Best Multi-Dealer Corporate Bond Trading Platform” in both the United States and Europe by Credit Magazine based on a poll of fixed-income investors. This is the third consecutive year that MarketAxess has been recognized as the Best Multi-Dealer Corporate Bond Trading Platform.

	•		We significantly expanded our recurring revenue base with the successful introduction of our new European high-grade fee plan.

	•		We leveraged our success in client-to-dealer Emerging Markets (EM) trading across new trading protocols and markets. We launched DealerAxess^® inter-dealer trading in EM Credit Default Swaps (CDS) and launched client-to-dealer local market trading, initially in bonds denominated in the local currencies of Mexico, Brazil and Argentina, in December 2007.

	•		We diversified our revenues and expanded our technology services capabilities through our acquisition of substantially all the assets of Trade West Systems, LLC (TWS), a financial software innovator that provides gateway adapters to connect order management systems (OMS) and trading systems to fixed-income trading venues.

	•		We significantly increased client connectivity, with approximately 150 client OMS connections established by the end of 2007. Trades executed directly from OMS connections in 2007 more than doubled, to 22% of all trades executed over the platform.
