Sustainability Pillar: Planet Leading by Example Decarbonizing the global economy is essential for long-term economic value creation and to sustain human life. From our position at the centre of Canadaʼs capital markets, we are committed to leading by example by continuing to integrate sustainability into our enterprise strategy, develop a climate transition plan to progress towards our emissions reduction targets and collaborate with stakeholders to support healthy ecosystems. Management of Climate Related Risks Our governance and enterprise risk management allows us to continuously manage climate-related risks and opportunities and help deepen and accelerate the integration of sustainability goals and objectives to the overall enterprise strategy and within each business unit. By proactively identifying issues most relevant to TMX Group and our stakeholders, we can respond and plan appropriately to address these risks. We assess the potential impact of physical and transition risks and opportunities from climate change based on time horizons of short-term (2 years), medium-term (5 years) and long-term (10 years). RISK TYPE DESCRIPTION MITIGATION & APPROACH TO RISK Physical Risk Acute and Chronic On a short-term and longer term basis, the increased severity of extreme weather events such as flooding, hurricanes, wildfires, cold or heat waves resulting from climate change could lead to power supply disruptions to key market infrastructure such as data centers and cloud infrastructure and/or create physical workplace access issues for employees. On a longer time horizon, changes in long-term climate conditions, including sea-level rise, changing patterns of precipitation, temperature or wind, could disrupt the production or operations of our listed issuers impacting their financial performance, with negative impacts to our business. We have a robust Business Resilience Management program to respond to disruptions when they arise. TMX Groupʼs Business Continuity Plans are designed to ensure continuous operations in the face of natural disasters and other physical risks associated with climate change. It is reviewed, at minimum, on an annual basis and more frequently if required. In addition to having a full back-up data centre which replicates our production data centre for technology resiliency, TMXʼs critical business operations are split between alternate office locations to provide redundancy if one of the sites cannot continue to operate, and TMX's global networks operate with a Point of Presence in the primary and secondary data centres of critical markets.
