This broad range of perspectives ensures that we can adapt our sustainability initiatives to serve evolving needs and trends. In keeping with our desire to lead in an authentic and purposeful manner, we will balance this broad range of perspectives with the results of a materiality assessment of our sustainability related risks and opportunities conducted in early 2025. This exercise, involving both internal and external stakeholders, will allow us to refresh our previous climate-specific materiality assessment and expand the assessment scope to include other sustainability topics. The results of this assessment are currently being analyzed and will be shared in our next report.
