TMX GROUP ANNOUNCES VOLUNTARY DELISTING OF SERIES D, E AND F DEBENTURES FROM TORONTO STOCK EXCHANGE

TMX Group Ltd.'s board of directors and the Toronto Stock Exchange have approved the voluntary delisting of the company's non-convertible Series D, E and F debentures from the TSX. In making the decision to delist, the company considered, among other things, the fact that secondary market trading in Canadian non-convertible corporate bonds occurs predominantly through over-the-counter markets, and this decision allows its fixed-income investors access to the deepest pool of liquidity. The total value of the Canadian corporate bond market is estimated at approximately $527-billion according to the FTSE Canada Corporate Bond Index. Originally listed in July, 2021, TMX Group's Series D, E and F debentures have traded less than $20-million in aggregate on the TSX through the end of February, 2024.

TMX Group intends to delist these debentures on or about April 26, 2024, and following delisting, they can continue to trade on the OTC markets. Neither the TSX, nor the terms of the trust indenture under which these debentures were issued require the company to obtain approval from debentureholders prior to delisting them from TSX.

The delisting impacts the following TMX Group debentures:

• Series D (TSX: X.DB.A): $300-million aggregate principal amount of 2.997 per cent Series D senior unsecured debentures due Dec. 11, 2024;
• Series E (TSX: X.DB.B): $200-million aggregate principal amount of 3.779 per cent Series E senior unsecured debentures due June 5, 2028;
• Series F (TSX: X.DB.C): $250-million aggregate principal amount of 2.016 per cent Series F senior unsecured debentures due Feb. 12, 2031.

TMX Group Series G, H and I debentures, issued in February, 2024, are not listed on the TSX and continue to trade OTC.
