They are long-tenured, talented leaders with deep customer relationships, clear strategic visions, and proven records of delivering results."

As Chief Operating Officer, Johnston will oversee the day-to-day operations of Cboe's global trading platforms, market operations, infrastructure, and clearing teams. He will work closely with Tim Lipscomb, EVP, Chief Technology Officer, who has been with Cboe for six years, to drive continued innovation, strengthen Cboe's technology and operations capabilities, and support the company's long-term growth.

As Executive Vice President, Global Head of Equities and Spot Markets, Fischer will oversee strategy, product development, and client engagement with an emphasis on delivering comprehensive on-exchange and off-exchange solutions for clients. Fischer will join Cboe from TMX Group, where she was Managing Director and President, TMX Alpha US, and brings over 25 years of industry experience with previous leadership roles at Deutsche Bank, Instinet, and Tucker Alan.

Fischer said, "It's an honor to join Cboe as the Global Head of Equities and Spot Markets. The momentum across the business is exceptional, and I'm excited to bring a fresh perspective as we expand our global footprint, strengthen client relationships, and enhance the markets we serve."
