SIX has announced the appointment of Bjørn Sibbern as Chief Executive Officer, effective January 1, 2025, replacing Jos Dijsselhof, who will remain at SIX until the end of February 2025 to ensure a smooth transition.

Jos Dijsselhof has reportedly resigned to pursue a new professional opportunity in the Middle East after seven years at SIX.

Bjørn Sibbern leads SIX’s international foreign exchange business as global head of exchanges and member of the group management since the beginning of 2024.

With over two decades of capital markets experience with renowned institutions, including various international roles at Nasdaq, OMX Exchanges and as CEO of E*TRADE Bank Denmark, Bjørn Sibbern was welcomed by the president of SIX, Thomas Wellauer.

“A recognized and highly connected capital markets expert from our ranks”

Thomas Wellauer, Chairman of SIX, said: “I am delighted that in Bjørn we have been able to appoint a recognized and highly connected capital markets expert from our ranks as our new CEO. Since we joined SIX a year ago, we have seen Bjørn as a strong, highly motivated and proactive leader. With his excellent background, Bjørn has the international expertise and leadership qualities necessary to continue and accelerate the growth of SIX.

“On behalf of the SIX Board of Directors, I would like to express our sincere gratitude to Jos for his dedicated leadership.

We wish Jos all the best in his new projects.

Jos Dijsselhof leaves SIX after strategic realignment

Outgoing Managing Director Jos Dijsselhof joined SIX as CEO in 2018. He played a central role in the company’s business development and the expansion of its international presence.

He successfully implemented the strategic realignment of SIX with the sale of the cards business to Worldline and further diversified the company’s business portfolio.

Under his leadership, SIX made key acquisitions – including the purchase of the Spanish stock exchange BME – as well as other international investments, notably in the financial information sector, which generated substantial and sustainable growth.
