NYFIX ACQUIRES FIXCITY

Transaction Enables NYFIX to Deliver a Unique Liquidity Discovery Solution

New York and London (April 9, 2008): NYFIX, Inc. (Nasdaq: NYFX), a trusted provider of innovative solutions that optimize trading efficiency, has today announced the acquisition of UK-based FIXCITY, a specialist in web-based electronic trading and liquidity discovery solutions. FIXCITY's flagship product ioinet is used by over 120 firms with desktop presence on 70 of Europe's premier buy-side institutions. ioinet is highly regarded for its sophisticated IOI (indications of interest) analysis, filtering, and alerting capabilities.

NYFIX will combine its IOI workflow expertise with FIXCITY's front end technology to deliver a unique liquidity discovery solution that will enable clients to swiftly capitalize on trading opportunities. Further differentiating the solution will be the depth of global IOI content that will result from the unification of the ioinet and NYFIX Marketplace communities and the resulting number of direct channels that will be integrated into buy-side desktops.

This acquisition is a continuation of NYFIX's strategy to aggregate liquidity for its clients and provide them with the real-time information they need to make the best trading decisions. This acquisition also adds significantly to NYFIX's global client base on the heels of the Company's recent launch of Euro Millennium, a neutral dark pool for Pan-European equities.

Commenting on the acquisition, Howard Edelstein, CEO, NYFIX, said: We are constantly trying to help our clients find the best trading opportunities in this increasingly fragmented market and are seeing the resurgence of IOIs as a primary source for liquidity discovery. FIXCITY has powerful, client-proven technology that addresses this challenge and I am looking forward to harnessing the power of our respective technologies, expertise, and global reach to deliver world-class trading solutions to our clients.

Bob Moitoso, Global Head of the FIX Division at NYFIX, said: NYFIX and FIXCITY have become leaders in the IOI business with different approaches. While NYFIX focused on delivering high quality IOIs directly into the buy-side trader's order management system for workflow efficiencies, FIXCITY approached it from a front-end analytical perspective. The reality is that clients want both - integration into their workflows, as well as visibility and control. We will combine our offerings to deliver a compelling and cost effective solution to the global trading community.

Paul Scott, Director, FIXCITY, added: This acquisition brings a wealth of advantages to our respective clients. Our enlarged community can look forward to greater global reach, including significant amounts of liquidity from NYFIX's sell-side Marketplace clients, and access to ioinet's advanced IOI analysis, filtering, and alerting functionality. With our combined team of forward-thinking professionals, we will continue to break new ground in delivering the best solutions possible for finding global sources of liquidity.
