Greenline’s suite of industry leading FIX testing and certification products includes VeriFIX for FIX testing and simulation, CertiFIX for certification and client support and MagniFIX for real-time monitoring of active FIX trading sessions. Greenline’s product portfolio supports FIX initiatives at any stage and in any trading environment. Through its professional services business, Greenline provides clients with custom system development and proprietary software solutions.

Richard M. McVey, chairman and chief executive officer of MarketAxess, commented, “We are excited about being part of developing market standards through accelerating growth in the use of FIX protocols. The acquisition of Greenline further broadens the range of technology services that we offer to institutional financial markets, provides a meaningful expansion of our client universe, including global exchanges and hedge funds, and further diversifies our business beyond our core electronic credit trading products.”

Acquisition Highlights
• Expansion and diversification of revenue base, complementing secondary trading-related revenue; extension of connectivity solutions beyond fixed-income, into equities and exchange-traded options, futures and commodities.

• Enhanced strategic/competitive position with addition of superior suite of FIX-related products and services in nascent fixed-income market; significant growth expected in FIX fixed-income end-users within next several years.
