COMPANY REITERATES GUIDANCE FOR FULL YEAR 2004

NEW YORK - May 3, 2004 - eSpeed, Inc. (NASDAQ:ESPD), the leading developer of electronic trading technology, today reported results for the first quarter ended March 31, 2004.

EARNINGS

eSpeed reported net income of $10.7 million, or $0.18 per diluted share, for the first quarter 2004 on a Generally Accepted Accounting Principles (GAAP) basis. To reflect earnings generated from the Company's operations, eSpeed also reports operating income. For the same period, the Company reported fully taxed operating income of $11.0 million, or $0.19 per diluted share. The difference between fully taxed operating income and GAAP net income was a $0.3 million non-cash charge for business partner securities. For comparative purposes, eSpeed reported pre-tax operating income of $18.0 million, or $0.31 per diluted share, in the first quarter 2004, compared to $10.1 million in pre-tax operating income, or $0.18 per diluted share reported in the first quarter 2003, 78 percent and 72 percent increases respectively.

REVENUES

eSpeed's total revenues for the first quarter 2004 were $44.6 million, 31 percent higher than total revenues of $34.0 million for the first quarter 2003. First quarter 2004 fully electronic revenues were $30.5 million, up 36 percent compared to $22.5 million in the first quarter 2003. Total revenues from Software Solutions in the first quarter 2004 were $7.1 million versus $5.8 million in the first quarter 2003, an increase of 22 percent.

First quarter 2004 pre-tax operating margins grew to 40.3 percent versus 29.6 percent in the first quarter 2003 and compared to 36.9 percent in the fourth quarter 2003.

Howard W. Lutnick, Chairman & CEO of eSpeed, commented, "We are proud to have reported strong top and bottom line results this quarter. Our pre-tax operating margin of over 40 percent for the first quarter clearly demonstrates the strength and leverage of our business model."

VOLUME & TRANSACTIONS

Fully electronic volume for the first quarter 2004 was $8.3 trillion, a 22 percent increase over $6.8 trillion for the first quarter 2003. eSpeed's total electronic volume, including fully electronic and voice-assisted transactions, for the first quarter 2004 was $11.9 trillion, up 27 percent from $9.4 trillion in the first quarter 2003. This growth compares to a 26 percent increase in US Treasury volume as reported by the Federal Reserve over the same period. Average daily Federal Reserve US Treasury volume was $481 billion for the first quarter.

Lee Amaitis, Vice Chairman of eSpeed, commented, "The continued success of our Price Improvement product enhancement was illustrated in the solid growth we saw this quarter in both revenues and volumes. We will continue to add value to our clients' execution capabilities with the introduction this quarter of our product enhancement Better Fill. We are excited to be able to offer additional proprietary trading tools that can improve the quality of our customers' trade executions and their profitability."

Fully electronic notional volume for new products, which we define as mortgage-backed securities, foreign exchange, interest rate swaps, and futures, was $133 billion in the first quarter 2004, compared to $21 billion in


the fourth quarter 2003. Volume for the eSpeed Equities direct access product was 85 million shares in the first quarter 2004, up from 56 million shares in the fourth quarter 2003. This is the first time eSpeed has reported these new metrics.

Additionally, the Company announced that it launched its U.S. Treasury repos product in early April. Data regarding this new product rollout will be reported with new product volume beginning in the second quarter.

Mr. Amaitis continued, "We are aggressively launching new products including repos, and while we are in the early stages of these initiatives, we are pleased to offer increased transparency into our new product volumes. As expected, no single new product has yet reached traction, but we are encouraged by our results over the last two quarters."

FREE CASH FLOW & CASH

The Company generated free cash flow of $2.4 million for the first quarter 2004. Excluding related party receivables and payables, free cash flow for the first quarter was $5.9 million. This free cash flow is net of a $7.2 million purchase of fixed assets. The Company is entitled to receive $19.5 million of replacement insurance related to September 11, 2001.

As of March 31, 2004, eSpeed's cash and cash equivalents was approximately $233 million.

OUTLOOK

The Company is maintaining its previously stated guidance for the full year 2004. eSpeed continues to expect to generate revenues in excess of $185 million and expects its pre-tax operating margins to exceed 41 percent for the full year 2004. eSpeed anticipates that its incremental margins will exceed 75 percent for the full year 2004. Operating earnings after tax for 2004 are expected to be in a range of $0.80 to $0.84 per diluted share. This guidance is based on the Company's expectations that average daily Federal Reserve US Treasury volume will be between $490 and $510 billion for the full year 2004.

For the second quarter 2004, eSpeed expects operating earnings to be in the range of $0.19 to $0.20 per share diluted and after-tax. This guidance is based on the Company's expectations that the average daily Federal Reserve US Treasury volume will be between $490 and $510 billion for the second quarter 2004.

In conclusion, Mr. Lutnick added, "As we look ahead for the rest of 2004, we remain confident in eSpeed's leadership position in US Treasuries, continue to have high expectations about the increased acceptance of our product enhancements, and are committed to successfully rolling out new products. To further ensure our success, we have strengthened our management team with the additions of Kevin Foley, our new President, and Paul Saltzman, our new Chief Operating Officer. With Kevin's extensive career that has been focused largely on the convergence of financial products and trading technology, along with his expertise in foreign exchange and equities, and Paul's relationships and experience in the fixed income markets, they are uniquely qualified to make a significant contribution toward our growth in new products and in our company."

NON-GAAP FINANCIAL MEASURES

To supplement eSpeed's consolidated financial statements presented in accordance with GAAP and to better reflect the Company's quarter-over-quarter and comparative year-over-year operating performance, eSpeed uses non-GAAP financial measures of revenues, income before income tax provision, net income and earnings per share, which are adjusted to exclude certain non-operating expenses and gains. In addition, the Company provides a computation of free cash flows. These non-GAAP financial measurements do not replace the presentation of eSpeed's GAAP financial results but are provided to improve overall understanding of the Company's current financial performance and its prospects for the future. Specifically, eSpeed believes the non-GAAP financial results provide useful information to both management and investors regarding certain additional financial and business trends relating to the Company's financial condition and results from operations. In addition, eSpeed's management uses these measures for reviewing the Company's financial


results and evaluating eSpeed's financial performance. In the first quarter 2004, the difference between GAAP net income and non-GAAP net operating income was $0.3 million.
