Item 2.02. Results of Operations and Financial Condition.

On March 30, 2005, NYFIX, Inc. (the "Company")  announced that it will delay the
filing of its 2004 Annual  Report on Form 10-K for the year ended  December  31,
2004 currently due March 31, 2005. The Company also announced that it will delay
filing  its   Management   Report  on  Internal   Control  as  required  by  the
Sarbanes-Oxley  Act of 2002. The Company had  anticipated  filing its Management
Report on Internal  Control by the extended  filing  deadline of April 30, 2005.
However, due to the delay in the filing of its Form 10-K, it no longer qualifies
for the automatic forty-five day extension. 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,  the Company expects to restate its audited  financial
statements  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 each of the first three quarters of 2004.
