TMX GROUP LIMITED REPORTS RESULTS FOR FOURTH QUARTER OF 2023

TMX Group Ltd. has released results for the fourth quarter ended Dec. 31, 2023.

Commenting on the organization's performance for 2023, John McKenzie, chief executive officer of TMX Group, said: "In a year of impressive performance milestones, we took definitive steps to strengthen TMX's ability to deliver modern solutions to a growing global client base, highlighted by the acquisition of VettaFi, a U.S.-based indexing, digital distribution and analytics company, completed last month. TMX reported record revenue in 2023, driven by double-digit gains from our Global Solutions, Insights and Analytics segment, including TMX Trayport and TMX Datalinx, and Derivatives Trading and Clearing, excluding BOX. The increases were partially offset by lower revenue from capital raising activity, and equities and fixed-income trading, due to challenging market dynamics. Looking ahead, we are focused on executing TMX's proven long-term growth strategy and innovating across our diverse business to make markets better for stakeholders around the world."

Commenting on the performance in the fourth quarter of 2023, David Arnold, chief financial officer of TMX Group, said: "Overall revenue for the fourth quarter grew 9 per cent year over year, driven by increases across all our key business areas. In addition to a demonstrated ability to deliver solid core business performance and increased cash flow, TMX remains firmly committed to investing for long-term growth. The strategic acquisition of VettaFi was funded with debt and enabled by the strength of our balance sheet. TMX has a proven track record of deleveraging following transactions, and we are confident in our ability to achieve our targeted leverage range two years postclose, as planned."
