NYFIX REPORTS UNAUDITED DIVISIONAL REVENUES FOR THE THREE MONTHS
ENDED MARCH 31, 2007

OVERALL REVENUES UP 17% OVER Q106

New York, NY June 13, 2007: NYFIX, Inc. (Pink Sheets: NYFX). NYFIX, a leader in technology solutions for the financial marketplace, announced today its divisional revenues for the three months ended March 31, 2007.

NYFIX cautions that the financial information noted below is preliminary and such amounts may differ from those included in quarterly and annual SEC filings. NYFIX will provide full results in accordance with GAAP upon the filing of its Form 10-Q for the period ended March 31, 2007. The Company expects to report losses for the first quarter of 2007 when it ultimately reports, reflecting the incurrence of restatement, SEC investigation and related expenses as well as certain transitional rebuilding expenses following the $75 million investment by Warburg Pincus.

Unaudited Revenues for the Three Months Ended March 31, 2007

Revenues for the three months ended March 31, 2007 were $27.7 million, an increase of 17% over the $23.7 million of revenues for the same period in 2006 and a 5% increase over the $26.4 million of revenues for the three months ended December 31, 2006. Revenues from the Company’s three operating divisions were as follows:

For the three months ended March 31, 2007, NYFIX incurred costs of $3.8 million related to the SEC investigation, the financial restatements and related litigation and other regulatory inquiries. Due to the completion of the restatement and the filing of the Company’s 2005 Form 10-K in March 2007, these costs are expected to decline going forward. Costs associated with related litigation and regulatory inquiries will continue.

Howard Edelstein, CEO, commented, “As we’ve said before, 2007 will be a year of transition for NYFIX as we make investments in both people and technology in order to scale our businesses for future growth. Another key priority is bringing our regulatory filings up-to-date and we look forward to becoming current with the SEC in the coming weeks.”
