NYSE Euronext is set to acquire around 25 percent of Fixnetix, a service provider of low latency data provision, co-location, trading services and risk controls for more than 50 markets worldwide.
More than 90 percent of Fixnetix's shareholders have already accepted the offer. Crucially, the agreement includes the option for NYSE Euronext to acquire the remainder of Fixnetix at any time over the next three years.
The Fixnetix technology will be sold through the NYSE Technologies subsidiary.
Michael Geltzeiler, group executive vice president and CFO of NYSE Euronext, said: "This further demonstrates NYSE Euronext's commitment to using our strong capital position to create immediate strategic value that delivers greater opportunities for the company." He said the deal "allows us to better leverage our combined technology presence to reach more customers in more locations".
Hugh Hughes, chief executive of Fixnetix, said the NYSE Euronext investment "will enable us to expand our US coverage and expand into Asia".
Although the companies will continue to operate independently, the pair will work together to offer customers integrated market access to "highly attractive liquidity venues in Europe, the Americas and Asia", said the pair.
Earlier this week hackers hit the websites of the NASDAQ and BATS stock exchanges. NASDAQ and BATS saw their sites disrupted during the day on Monday. The sites host company news and share price data, as well as vital information on live service status on the exchanges. Trading on the actual exchanges was unaffected.
