2025 Annual Sustainability Report

(b) Describe managementʼs role in monitoring, managing, and overseeing climate-related risks and opportunities, including the identity of the management-level position or committee as applicable, its governance processes, controls, and procedures, and how oversight is exercised over that position or committee. 91ÁÔÆæ Trust holds quarterly Risk Management Committee meetings in which risks affecting or that could affect the business are identified and addressed by the relevant internal stakeholders. The Risk Management Committee (a 91ÁÔÆæ Trust senior management committee) makes any required recommendations to the Risk & Audit Committee (a 91ÁÔÆæ Trust Board committee), which then makes a recommendation to the 91ÁÔÆæ Trust Board of Directors as needed. Sustainability objectives are tracked for 91ÁÔÆæ Trust through TMX Groupʼs Objective Centric Risk Management (“OCRMË®) approach which identifies the risks, mitigations and opportunities that need to be considered and/or implemented in order to realise the successful achievement of TMX Groupʼs objectives. Quarterly reports on OCRM objectives are reviewed by the 91ÁÔÆæ Trust Risk & Audit Committee and its President/CEO. Implementation and expansion of this disclosure expectation into 91ÁÔÆæ Trustʼs governance framework is on track for completion in 2026.
