News Releases

NEW YORK AND TOKYO, January 29, 2008 –NYSE Euronext (NYSE: NYX), today announced the expansion of its office in Tokyo with the addition of a team from NYSE TransactTools^SM. The company’s new Tokyo presence further establishes NYSE Euronext’s commitment to the Asia-Pacific region, and investment in local infrastructure to support the rapid growth of sophisticated electronic trading.  The NYSE TransactTools Tokyo team, led by Peter Tierney, NYSE TransactTools Managing Director for Asia-Pacific, is already involved in a growing number of high performance trading infrastructure projects with Japan-based sell-side and exchange clients.

Since its establishment in 1999, the NYSE Euronext Tokyo office has concentrated on meeting the needs of Japanese companies listed on the NYSE.  At present, 21 of Japan’s leading companies, with a combined market capitalization of nearly $900 million, are listed on NYSE Euronext markets.  The additional presence of NYSE TransactTools   marks a new stage in the development of NYSE Euronext’s Japan business, and will help the company meet the needs of its clients doing business in Japan.

NYSE TransactTools is seeing higher demand for direct electronic trading access across Asia-Pacific markets, and has recently added native support for Tokyo markets to its Direct Market Access Gateway (DMAG) product.  The DMAG combines the privacy, low latency and high throughput of direct market access with the control and risk management of traditional broker-routed flow.  Built around the same core technology as the Common Customer Gateway (CCG) that will provide high-performance access across all NYSE Euronext markets, DMAG combines the industry’s fastest message routing with sophisticated in-link risk management and control on a standardized technology platform—an industry first.

Lawrence Leibowitz, Executive Vice President and COO of U.S. Products of NYSE Euronext, said, “As the Asian capital markets continue their rapid growth, the demand for advanced trading technology and for sophisticated linkages between the U.S., Europe, and Asia will continue to grow.  Our enhanced presence in Tokyo will help facilitate this growth, and enable us to serve the needs of our customers throughout Asia.”

Many of the world’s leading securities trading firms are welcoming the addition of the NYSE TransactTools presence to the NYSE Euronext Tokyo office.  Morgan Dunbar, co-head of Electronic Execution Services, Nikko Citigroup Limited said, “NYSE TransactTools is an important partner of Citi’s high performance global electronic execution services and we are excited to see this investment in Japan.  We look forward to working with them here as we expand our offering in this market and wish them continued success.”

Added Atsushi Saito, President and CEO of the Tokyo Stock Exchange, “TSE enjoys a close relationship with NYSE Euronext and the opening of their technology subsidiary in Tokyo will enhance our cooperation even further.”

“Our customer engagements in the US and Europe are increasingly focused on replacing “legacy” electronic trading infrastructure to better cope with the demands of latency sensitive DMA and Algo trading,” said Sam Johnson, Executive Vice President of NYSE TransactTools. “In Japan we are also seeing this refresh cycle, combined with an increasing number of local firms that wish to enter the electronic order routing space with the highest performance infrastructure.  We are very pleased to be able to work directly with these firms to build Japan-centric solutions.”

NYSE Euronext, the world’s largest and most liquid exchange group, continues to build its operations in Asia.  In addition to its expanded presence in Tokyo, the company has offices in Beijing, Hong Kong, and Singapore.
