Luis Laginha de Sousa will succeed Miguel Athayde Marques, who has decided to resign his positions with NYSE Euronext to pursue other professional opportunities. Luis Laginha, who is currently Chief Operating Officer in Lisbon, will also become a member of the Managing Board of Euronext N.V. and the Management Committee of NYSE Euronext.

"Under Miguel's leadership, our Lisbon exchange has performed exceptionally well and provided outstanding service to issuers, investors and all market participants," said Duncan Niederauer, CEO, NYSE Euronext. "Miguel has been instrumental in both growing and transforming our business, and my colleagues and I are truly grateful for his partnership and commitment to the organization and our goals."

"Miguel has made significant contributions to NYSE Euronext and the Lisbon market," said Dominique Cerutti, President and Deputy CEO, NYSE Euronext. "On behalf of our organization, I would like to thank Miguel for his valuable service and leadership, and wish him all the best for the future. I also welcome the appointment of Luis as Chairman and CEO of NYSE Euronext Lisbon and look forward to working with him."

Miguel Marques said, "Serving the Portuguese market and our customers for the past five years as head of our Lisbon exchange has been a great privilege, in addition to working with a great team of professionals and play a leadership role in the transformation of our company and the industry. We realized the globalization of our company through the first ever transcontinental merger of exchange companies, and NYSE Euronext is well positioned for the future. While for me this is the right time for a new challenge, it is reassuring that we have a fitting successor in Luis Laginha, who possesses the outstanding qualities both as a professional and as an individual to build on the success of NYSE Euronext and the Portuguese market."

Luis Laginha said: "It is a great honour to succeed Miguel Marques, whos, whose example will continue to provide a valuable inspiration for the challenges ahead. I am confident that with the support of my colleagues, we will be capable not only of preserving, but also expanding the role of NYSE Euronext in the local Portuguese market for the benefit of our customers and all stakeholders."
