Pan-European exchange group Euronext has picked a Santander investment banker as its next chief executive, ending a near-five month search to succeed Dominique Cerutti, who resigned in April.

Stéphane Boujnah, a lawyer by training and a former banker covering technology and telecoms at Deutsche Bank, where he worked from 2005 to 2010, and Credit Suisse First Boston, where he was part of the European technology M&A team from 2000 to 2002, has been approved as Euronext's CEO by the exchange group's nomination and governance committee, according to a statement on September 10.
