XL’s 2025 Environment, Social and Governance Materiality Assessment

As part of XL’s ongoing commitment to strengthening our sustainability practices and aligning our work with the expectations of our clients, partners, and employees, we conducted a comprehensive Environment, Social and Governance (ESG) materiality assessment in Q3 2025. This effort engaged nearly 200 stakeholders, including executive leaders, employees, clients, and strategic partners, to help us identify and prioritize the ESG topics most meaningful to our business and the communities we serve.

The assessment revealed alignment across key themes and provided valuable insights into areas where perspectives differed, including diversity and inclusion, global climate impacts, and union engagement. These findings directly informed the development of our Strategic Sustainability Priorities:

• Climate: Reducing greenhouse gas emissions, advancing waste diversion, and enhancing energy management
• Workplace: Continuing to prioritize the health and safety for our teams, foster a strong workplace culture, and investin workforce development
• Trust and Transparency: Strengthening internal governance and upholding our Code of Business Conduct

These priorities will guide our long‑term planning, decision‑making, and ESG initiatives across the organization.
