Insights

Corporate governance analyst

Trex outlines an orderly internal CEO succession with clarified pay and transition terms.

Trex is moving from long-serving CEO Bryan Fairbanks to insider successor Adam Zambanini on April 28, 2026. The company emphasizes this is a planned transition without disagreement, which usually signals continuity in strategy and culture.

The Board boosts Zambanini’s compensation to a $900,000 salary, a 110% target annual bonus, and equity targets at 450% of salary, aligning his package with a typical public-company CEO profile. Severance and change-in-control terms will mirror those of the outgoing CEO, aiming for consistency in protections.

Fairbanks’ transition and consulting arrangements, including monthly consulting fees of $16,666 and continued vesting of certain equity awards through April 30, 2027, are structured to preserve his experience during the handover. Future filings and earnings communications around and after the April 28, 2026 handoff will help show how smoothly leadership and operational responsibilities transfer.

James Cline, Chairman of the Board of Directors, said “Bryan has made an immeasurable mark on the organization and embodies Trex’s core qualities – vision, innovation and discipline. In determining a successor, the Board undertook a comprehensive evaluation process, including assessing both internal and external candidates, and Adam was the clear and most capable successor to Bryan. He is a strong leader and brand-builder and his knowledge of Trex’s business, product roadmap, markets and people is unmatched. Adam has been a true partner to Bryan in developing our strategic initiatives and product innovation, which will be an important advantage as he steps into his new role.”

Mr. Zambanini, said, “It is an honor to succeed Bryan, someone who has made an impact on me and so many across Trex. As I assume the role as the Company’s next CEO, I am energized by the opportunity to partner with our dynamic leaders and continue to drive growth and shareholder value. Trex is the undisputed leader in wood-alternative decking and railing and I am confident that Trex will continue to win in our markets and categories, while building on our strong financial profile.”

“After a nearly 23-year career at Trex, including the past six years as CEO, now is the right time to transition leadership to Adam as part of our succession plan,” said Mr. Fairbanks. “I have had the opportunity to work with the best talent in our industry and lead our iconic Trex brand that has shaped the decking industry and delivered above market returns for our investors. Having worked closely with Adam for two decades, I have been impressed with his leadership capabilities and his drive for performance. I take pride in what we have built and move on with confidence in Trex’s future.”

Mr. Cline concluded, “Six years ago, Bryan was announced as CEO and during his tenure he has grown Trex, shown resilience within a challenging industry environment, strategically invested to enhance the Company’s future position and built a world-class team of innovators and operators that have consistently delivered for our channel partners and consumers. On behalf of the Board and the Trex

team, we owe Bryan our deepest appreciation and thank him for his continued support to ensure this is a seamless transition for all stakeholders.”
