TMX GROUP LIMITED NORMAL COURSE ISSUER BID APPROVED

TMX Group Ltd.'s normal course issuer bid has been accepted by Toronto Stock Exchange.

Under the NCIB, TMX Group may purchase up to 2.8 million of its common shares by way of normal course purchases on Toronto Stock Exchange, representing approximately 1 per cent of the 278,232,220 common shares outstanding on Feb. 20, 2026. The maximum number of shares that can be purchased on the same trading day on TSX is 155,315 shares (25 per cent of the average daily trading volume for the six months ended Jan. 31, 2026, which was 621,261 shares), other than block purchase exceptions. The purchases may commence on Feb. 27, 2026, and will terminate on Feb. 26, 2027, or on such earlier date as TMX Group completes its purchases.

TMX Group will make purchases in accordance with TSX requirements, and the price TMX Group will pay for any such common shares will be the market price of such shares at the time of acquisition. All purchases will be effected through the facilities of TSX. All repurchased shares will be cancelled. TMX Group has not purchased any of its shares in the past 12 months.

TMX Group also entered into a predefined plan with its designated broker to allow for the repurchase of common shares at times when TMX Group ordinarily would not be active in the market due to its own internal trading blackout periods, insider trading rules or otherwise.

TMX Group believes that the purchase of common shares from time to time can be undertaken at prices that make the acquisition of such shares an appropriate use of available funds and an appropriate mechanism for returning capital to its shareholders.
