NEW YORK, April 27, 2011 — 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 first quarter ended March 31, 2011.

“Our record first quarter results reflect continuing U.S. high grade market share gains, which have expanded from 7.9% a year ago to 9.9% in the first quarter of 2011, and strong volume growth in our other product category,” said Richard M. McVey, chairman and chief executive officer of MarketAxess. “Operating margins exceeded 40% for the first time and have doubled in the past two years. The pace of margin improvement is a demonstration of the significant operating leverage in our business.”

First Quarter Results

Total revenues for the first quarter of 2011 increased 25.0% to $43.6 million, compared to $34.9 million for the first quarter of 2010. Pre-tax income was a record $17.7 million, compared to $11.1 million for the first quarter of 2010, an increase of 59.4%. Pre-tax margin was 40.5%, compared to 31.8% for the first quarter of 2010. Net income totaled $10.8 million, or $0.27 per share on a diluted basis, compared to $6.7 million, or $0.17 per share on a diluted basis, for the first quarter of 2010.

Commission revenue for the first quarter of 2011 totaled $37.8 million on total trading volume of $135.2 billion, compared to $29.3 million in commission revenue on total trading volume of $99.2 billion for the first quarter of 2010. U.S. high-grade trading volume as a percentage of FINRA’s high-grade TRACE trading volume increased to an estimated 9.9%, compared to an estimated 7.9% for the first quarter of 2010.

Technology products and services revenue, which includes revenue for technology licenses, support and professional services, totaled $3.1 million for the first quarter of 2011, compared to $3.2 million for the first quarter of 2010. Other revenue, which consists of information and user access fees, investment income and other revenue, increased 12.6% to $2.7 million, compared to $2.4 million for the first quarter of 2010.

Total expenses for the first quarter of 2011 increased 9.0% to $25.9 million, compared to $23.8 million for the first quarter of 2010. Full year 2011 expenses are now expected to be towards the upper end of the guidance range of $101 million to $107 million. The increase in expenses during the first quarter of 2011 was primarily due to higher employee compensation and benefits expense of $2.3 million and professional and consulting fees of $0.7 million, offset by a decline in general and administrative expenses of $1.1 million. The decline in general and administrative expenses was primarily due to the settlement of a favorable sales tax reimbursement claim amounting to approximately $0.7 million.

The effective tax rate for the first quarter of 2011 was 39.0%, compared to 39.5% for the first quarter of 2010.

Employee headcount as of March 31, 2011 was 232, compared to 219 as of March 31, 2010.

Dividend

The Company’s board of directors declared a quarterly cash dividend of $0.09 per share of common stock outstanding or issuable upon conversion of outstanding shares of non-voting common stock, to be paid on May 25, 2011 to stockholders of record as of the close of business on May 11, 2011.

Balance Sheet Data

As of March 31, 2011, total assets were $303.7 million and included $196.2 million in cash, cash equivalents and securities. Total stockholders’ equity as of March 31, 2011 was $281.4 million. The Series B preferred stock was automatically converted to common stock on January 24, 2011. This conversion does not impact the computation of diluted weighted-average common shares outstanding.

Non-GAAP Financial Measure

EBITDA 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 operating results. See attached schedule for a full reconciliation of GAAP net income to EBITDA.
