Changes at SIX Executive Board

Marion Leslie will join SIX as Head of the Financial Information business unit as of 1 January 2020. Marion Leslie has many years of experience and a proven track record in the international financial information business. Robert Jeanbart, Business Unit Head Financial Information, has decided to take retirement and will be leaving SIX at the end of December 2019.
Robert Jeanbart joined the Executive Board of SIX in May 2014, since which time he has been responsible for the Financial Information business unit. Robert Jeanbart successfully restructured the Financial Information business unit of SIX, focusing the Unit on its core business, streamlining its Swiss and international operations and developing new business areas, hence putting the Unit on a sustainable profit path. In particular, Financial Information significantly expanded its business in the regulatory data and services while strengthening its reference data and corporate actions business, and in doing so strengthened the market position of SIX in this highly competitive landscape.

Marion Leslie will take over the leadership of Financial Information as of 1 January 2020 and will thus become a member of the SIX Executive Board. She began her career at Refinitiv (formerly Thomson Reuters) in 1994. After holding various management roles within the company, she became Managing Director in 2013 with responsibility for the data business in the areas of regulation, pricing and reference data. In her last role at Refinitiv, Marion was the Managing Director, Enterprise, with responsibility for delivering market data, platforms and services to the global financial markets. Leading global businesses and operations at scale, with a strong emphasis on data and technology, are the hallmarks of her career. Marion Leslie will move with her family from the UK to Switzerland.

Jos Dijsselhof, CEO SIX: “I am very pleased to welcome Marion Leslie to SIX. I am proud to have been able to attract such an experienced professional and internationally active leader for SIX. Marion knows the financial information business very well and with her at the helm we will drive our financial data business to the next level. On behalf of the Board of Directors and the Executive Board of SIX, I would like to thank Robert Jeanbart for his enormous and tireless dedication to SIX, his leadership in driving a very successful transformation of Financial Information.”
