Often, but not always, such forward-looking information can be identified by the use of forward-looking words such as "plans", "expects", "is expected", "budget", "scheduled", "targeted", "estimates", "forecasts", "intends", "anticipates", "believes", or variations or the negatives of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved or not be taken, occur or be achieved. Forward-looking information, by its nature, requires Íâ¹úÃÀŮɫÇéƬ to make assumptions and is subject to significant risks and uncertainties which may give rise to the possibility that our expectations or conclusions will not prove to be accurate and that our assumptions may not be correct.

These risks include: competition from other exchanges or marketplaces, including alternative trading systems and new technologies, on a national and international basis; dependence on the economies of Canada and the United States; adverse effects on our results caused by global economic conditions or uncertainties including changes in business cycles that impact our sector; failure to retain and attract qualified personnel; geopolitical and other factors which could cause business interruption; dependence on information technology; vulnerability of our networks and third party service providers to security risks, including cyber attacks; failure to properly identify or implement our strategies; regulatory constraints; constraints imposed by our level of indebtedness, risks of litigation or other proceedings; dependence on adequate numbers of customers; failure to develop, market or gain acceptance of new products; failure to effectively integrate the VettaFi acquisition, to achieve planned economics or divest underperforming businesses; currency risk; adverse effect of new business activities; adverse effects from business divestitures; not being able to meet cash requirements because of our holding company structure and restrictions on paying dividends; dependence on third party suppliers and service providers; dependence of trading operations on a small number of clients; risks associated with our clearing operations; challenges related to international expansion; restrictions on ownership of Íâ¹úÃÀŮɫÇéƬ common shares; inability to protect our intellectual property; adverse effect of a systemic market event on certain of our businesses; risks associated with the credit of customers; cost structures being largely fixed; the failure to realize cost reductions in the amount or the time frame anticipated; dependence on market activity that cannot be controlled; the regulatory constraints that apply to the business of Íâ¹úÃÀŮɫÇéƬ and its regulated subsidiaries, costs of on exchange clearing and depository services, trading volumes (which could be higher or lower than estimated) and revenues; future levels of revenues being lower than expected or costs being higher than expected.

Non-GAAP Measures

Both Adjusted earnings per share and the leverage ratio provided above are non-GAAP ratios and do not have standardized meanings prescribed by GAAP and are therefore unlikely to be comparable to similar measures presented by other companies. Adjusted EPS excludes, among other things, acquisition related costs, integration costs,and amortization of intangibles related to acquisitions and other items as disclosed in our Q3 2023 MD&A; and the leverage ratio is defined as total long term debt and debt maturing within one year divided by Adjusted EBITDA. Adjusted EBITDA is calculated as net income excluding interest expense, income tax expense, depreciation and amortization, transaction related costs, integration costs, one-time income (loss), and other significant items that are not reflective of Íâ¹úÃÀŮɫÇéƬ's and VettaFi's underlying business operations. For more information on adjusted EPS and debt to adjusted EBITDA including definitions and explanations of how these measures provide useful information, refer to the Non-GAAP Measures section in Íâ¹úÃÀŮɫÇéƬ's Q3-2023 Management's Discussion and Analysis dated October 30, 2023, which is incorporated by reference into this press release and which is available on Íâ¹úÃÀŮɫÇéƬ's website at www.tmx.com and on SEDAR+ at .
