Item 8.01. OTHER EVENTS.

On May 10, 2005,  NYFIX,  Inc. (the "Company")  announced that it will delay the
filing of its first quarter 2005 report on Form 10-Q for the quarter ended March
31, 2005 currently due May 10, 2005. The text of the press release issued by the
Company is furnished as Exhibit 99.1 and is incorporated herein by reference.

As previously announced by the Company, the delay is a result of its expectation
to restate its audited financial  statements after a review of previously issued
stock options. The Company is in the process of restating its audited financials
for the years  ended  December  31,  2003 and 2002  included  in its 2004 Annual
Report on Form 10-K and is evaluating  whether it needs to restate its unaudited
results for the first three quarters of 2004.
