TMX to take 59% stake in MEMX in US$800million cash deal, forming US$2.3billion exchange group
TMX Group, the parent of the Toronto Stock Exchange, said it will invest US$800million in cash in U.S. exchange operator and market-technology provider MEMX and take a 59% controlling stake. TMX will also combine BOX, the U.S. equity options market it controls, with MEMX to form a US$2.3billion entity. The move extends TMX’s acquisition push since 2023, including the purchases of VettaFi and RAFI Indices. It comes alongside TMX’s efforts to buy Cboe’s Canadian and Australian assets.
