TMX Group Limited (TMX Group) has completed the acquisition of Middlebury Holdings Pty. Limited (Cboe Australia) from Cboe Global Markets, Inc. The transaction was first announced in April 2026.
The transaction will bolster TMX Group’s ability to serve clients across the capital markets ecosystem, expand the company’s global presence and accelerate the company’s growth strategy. TMX’s acquisition of Cboe Australia will bring together the world’s leading mining and energy transition financing ecosystems, unlocking potential to innovate for a growing global client base.
Cboe Australia, which will be rebranded as TMX Australia Exchange, is an innovative securities exchange offering companies strategic tailored support for public market listings, including ETFs, as well as structured products and warrants, and providing a trading venue for brokers and investors with efficient and cost-effective access to local and global investment opportunities. Cboe Australia was also recently granted a license for corporate listings.
“We are tremendously excited to announce the acquisition of Cboe Australia and Cboe Canada, a deal that represents a unique opportunity to strengthen our domestic marketplace for clients and the entire stakeholder ecosystem, while expanding the reach and impact of our presence in a region of the world we know well,” John McKenzie, Chief Executive Officer, TMX Group said at the time of the announcement.
