In a bold move that reverberates across Europe’s trading landscape, SIX Exchange Group AG has finalized its £207 million ($285 million) acquisition of Aquis Exchange PLC, the London-based challenger exchange. This deal, long in the pipeline since Aquis' board backed it last November, now positions SIX as a dominant force in pan-European financial markets.

The deal offered Aquis shareholders 727 pence per share in cash, a premium reflecting SIX’s ambition to tap into the beating heart of Europe’s startup and mid-cap equity markets.

Challenging the Status Quo in London’s Financial Arena

Aquis isn’t just another exchange—it’s a rising contender in the European financial arena, directly competing with London’s Alternative Investment Market (AIM). With a focus on growth companies, Aquis offers both primary and secondary markets for equity and debt securities, supporting entrepreneurial ventures across sectors.

Now under SIX’s umbrella, Aquis becomes part of a much larger strategic chessboard. SIX, headquartered in Zurich, says the acquisition significantly expands its listing capabilities and strengthens its pan-European trading ecosystem.

“The acquisition of Aquis marks a significant milestone in the evolution of SIX as a pan-European leader,” said Bjørn Sibbern, CEO of SIX. “We gain not only access to new markets but also the technology and expertise needed to drive innovation at scale.”

Green Lights from Regulators and Legal Heavyweights Behind the Deal

The deal cleared all necessary regulatory hurdles, including approvals from both the UK Competition and Markets Authority and the European Commission, paving the way for Tuesday’s finalization announcement.

Behind the scenes, some of the most powerful legal minds in global finance were orchestrating the deal:

• SIX was legally advised by Clifford Chance LLP

• Aquis was represented by elite firm Slaughter and May

• UBS AG, which acted as financial adviser to SIX, received legal counsel from Herbert Smith Freehills Kramer LLP

A Platform for Innovation and Expansion

This isn’t just about market reach—it’s about future-proofing. Aquis brings with it cutting-edge trading technology and regulatory expertise, making the merger a springboard for innovation.

SIX, which already owns and operates the Swiss Stock Exchange, can now offer listing venues in every major European financial hub, from Zurich to London and beyond. With cross-border capabilities and an eye on growth, the group’s latest move puts it in pole position to shape the next chapter of European capital markets.
