NEW YORK, February 3, 2010— 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, 2009.

“Our record fourth quarter results reflect the continuing benefits of our drive over the past 18 months to expand our trading network to improve liquidity for credit market participants,” said Richard M. McVey, chairman and chief executive officer. “Greater electronic trading connectivity allowed us to take advantage of improved market conditions leading to record quarterly income before taxes, a doubling of volumes and a 140% increase in variable transaction fees from a year ago. ”

Fourth Quarter Results

Total revenues for the fourth quarter of 2009 increased 55.6% to a record $34.0 million, compared to $21.8 million for the fourth quarter of 2008. Pre-tax income was a record $11.0 million, compared to

1

$3.0 million for the fourth quarter of 2008, an increase of 266.5%. Pre-tax margin was 32.5%, compared to 13.8% for the fourth quarter of 2008. Adjusted net income totaled $6.7 million or $0.17 per share on a diluted basis, excluding a non-cash income tax charge of $1.3 million or $0.03 per share, compared to $1.9 million, or $0.05 per share on a diluted basis, for the fourth quarter of 2008. Net income totaled $5.4 million, or $0.14 per share on a diluted basis. The non-cash income tax charge resulted from an adjustment to our deferred tax asset to reflect an anticipated reduction in the rate at which we will pay state and local taxes in the future. We anticipate that the overall effective tax rate for 2010 will be between 39% and 41%.

Commission revenue for the fourth quarter of 2009 increased 69.3% to $28.6 million compared to $16.9 million for the fourth quarter of 2008. Variable transaction fees totaled $16.6 million on total trading volume of $92.0 billion, compared to variable transaction fees of $6.9 million on total trading volume of $43.2 billion for the fourth quarter of 2008. U.S. high-grade trading volume as a percentage of FINRA’s high-grade TRACE trading volume increased to an estimated 8.1%, compared to an estimated 5.2% for the fourth quarter of 2008 and 6.5% for the third quarter of 2009.

Technology products and services revenue, which includes revenue for technology licenses, support and professional services, increased 24.0% to $3.1 million, compared to $2.5 million for the fourth quarter of 2008. Other revenue, which consists of information and user access fees, investment income and other revenue, decreased 6.1% to $2.3 million, compared to $2.5 million for the fourth quarter of 2008.

Total expenses for the fourth quarter of 2009 increased 21.8% to $22.9 million, compared to $18.8 million for the fourth quarter of 2008. The increase was primarily due to higher employee compensation and benefits expense of $3.7 million as a result of increased incentive compensation that varies based on operating results and increased headcount. Employee headcount as of December 31, 2009 was 212, compared to 185 as of December 31, 2008.

Full Year 2009 Results

Total revenues for the year ended December 31, 2009 increased 22.9% to a record $114.4 million, compared to $93.1 million for 2008. Pre-tax income was a record $30.0 million, compared to $12.8 million for 2008, an increase of 134.1%. Pre-tax margin was 26.3%, compared to 13.8% for 2008. Adjusted net income totaled $17.4 million or $0.46 per share on a diluted basis, excluding the non-cash income tax charge in the fourth quarter of $1.3 million or $0.03 per share, compared to $7.9 million, or $0.22 per share on a diluted basis, for 2008. Net income totaled $16.1 million, or $0.42 per share on a diluted basis.

Commission revenue for the year ended December 31, 2009 increased 30.7% to $96.1 million, compared to $73.5 million for 2008. Variable transaction fees increased 81.6% to $52.8 million on total trading volume of $299.3 billion, compared to variable transaction fees of $29.1 million on total trading volume of $226.5 billion for 2008.

Technology products and services revenue totaled $9.8 million for the year ended December 31, 2009, compared to $8.6 million for 2008. Other revenue decreased 22.5% to $8.5 million, compared to $11.0 million for 2008, primarily due to a decline in investment income as a result of lower interest rates.

Total expenses for the year ended December 31, 2009 increased 5.2% to $84.4 million, compared to $80.3 million for 2008. The increase was primarily due to higher employee compensation and benefits expense of $6.5 million, offset by decreases in depreciation and amortization expenses of $1.1 million and professional and consulting fees of $1.3 million. Capital spending for the year ended

2

December 31, 2009 was $6.8 million and included $2.2 million in expenditures related to our new premises.

The effective tax rate for 2009 was 46.4%, compared to 38.5% for 2008. The 2009 provision for income taxes includes the fourth quarter adjustment of $1.3 million to our deferred tax asset balance and the effect of a greater portion of our earnings generated in higher tax rate jurisdictions.

Dividend

The Company’s board of directors declared a quarterly cash dividend of $0.07 per share of common stock outstanding or issuable upon conversion of outstanding shares of non-voting common stock and Series B preferred stock, to be paid on March 3, 2010 to stockholders of record as of the close of business on February 17, 2010.

Balance Sheet Data

As of December 31, 2009, total assets were $277.3 million and included $174.3 million in cash, cash equivalents and securities, and a deferred tax asset of $24.0 million. Total stockholders’ equity, including the Series B preferred stock, as of December 31, 2009 was $246.8 million.

Guidance for 2010

The Company expects total expenses for 2010 to be in the range of $90.0 million to $94.0 million.

The Company expects its full year 2010 capital spending, which includes approximately $3.0 million in expenditures relating to our new premises, to be in the range of $7.0 million to $9.0 million.

We anticipate that the overall effective tax rate for 2010 will be between 39% and 41%.

Non-GAAP Financial Measure

Adjusted net income is a non-GAAP financial measure. The Company believes that this non-GAAP financial measure, when taken into consideration with the corresponding GAAP financial measure, is important in gaining an understanding of the Company’s ongoing business and to provide for comparative results from period to period.
