TMX Group Limited announced it has completed the acquisition of Middlebury Holdings Pty. Limited (Cboe Australia) from Cboe Global Markets, Inc. The transaction was 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.
