A MESSAGE FROM OUR PRESIDENT AND CEO
LOGO USAGE Trex designs for the people who use our products today—and for those who will inherit them tomorrow.

We measure performance not only by immediate results, but also by the durability of our strategy, the resilience of our operations and the legacy we leave behind.
schools, retailers and community organizations to encourage them to collect waste plastic film and entrust Trex to recycle it. These partnerships build brand awareness, deepen community engagement and support future growth. We grow alongside the communities we call home. Through charitable giving, employee volunteering and partnerships like NexTrex®, we support local organizations, schools and nonprofits working to strengthen education, operational strength and economic opportunity. In 2025, Trex and our employees directed hundreds of thousands of dollars to community causes and continued our long-standing relationship with United Way. These investments reflect our belief that strong communities are essential to long-term business success. The values we hold today are the foundation for our future success. I am proud of our accomplishments in 2025 and confident that Trex is well positioned to continue leading our category, creating durable value for our customers, our shareholders and the generations to come.
These efforts contribute to business performance by enhancing productivity, supporting cost discipline and strengthening the resilience of our operations. Strong governance and environmental compliance protect enterprise value. That is why our governance structure integrates sustainability into strategic decision-making, supported by independent Board oversight and clear accountability. We continue aligning our disclosures with global reporting standards and maintaining a culture grounded in transparency, compliance and trust. Our success is inseparable from the well-being and performance of our people. We invest in our team members’ careers at all levels, from leadership to new hires. Recognition programs such as our Distinguished Performance Awards reinforce and celebrate excellence, ensuring that our culture supports sustained high performance. I am pleased to report that in 2025, we reduced both our lost-time incident rate and total recordable incident rate to well below industry averages through targeted risk management and safety engagement.
Today: Driving Operational Performance and Resilience
Circularity has been at the center of our business for nearly 30 years, since Trex first pioneered composite decking made from recycled and reclaimed materials. Today, 95% of the raw materials in our composite decking come from waste wood and recycled plastic films. In 2025 alone, we sourced nearly one billion pounds of recycled and reclaimed materials. The Trex magic is creating premium quality, durable, beautiful products from these materials. Our customers get to enjoy our products in their homes while we quietly reduce landfill waste, conserve natural resources and reduce demand for virgin timber and plastic production. We apply decades of innovation to our manufacturing. Quality and efficiency are built into our processes, enabling us to reduce energy demand, conserve water and minimize waste. In 2025, we strengthened our environmental management systems, expanded energy efficiency initiatives and audited our waste streams to identify additional efficiency opportunities.
Tomorrow: Positioning Trex for Long-Term Growth
Trex is built for the future—for our customers and our shareholders. Our sustainability credentials enhance our brand strength and category leadership. As new generations enter the housing market, our unique innovations position us to expand market share and lead responsibly. Customers are also community members, and our NexTrex® recycling network connects with an ever-increasing number of
