CEO Commentary

"We are well on the way on our journey to re-engineer Tredegar into a stronger operating company and create sustainable shareholder value," said Dr. Arijit (Bapi) DasGupta, president and chief executive officer. "Thus far in 2026, we have made substantial progress through our One Tredegar initiative, bringing our businesses under unified enterprise leadership, simplifying the organization, removing functional redundancies and strengthening key capabilities. These changes are creating clearer accountability, faster decision-making and a stronger foundation for improving operating performance, generating cash and allocating capital with greater discipline."

"An important part of this transformation has been strengthening our leadership team and putting the right people in critical roles across the organization. We have added experienced leaders in key areas and are building a more capable, accountable and execution-focused organization to help drive the next phase of One Tredegar."

"Looking at our third-quarter results – clearly – they were not where we want them to be.^{5 5}We faced broader market pressures, but we also have areas where we need to better execute.⁵ At Bonnell, profitability was significantly affected by lower shipments amid continued pressure on building and construction demand, as well as the timing lag of the pass-through of metal costs. High Performance Films experienced lower Surface Protection demand and an unfavorable customer and product mix, along with resin-cost pressures. We are responding with urgency to the factors we can control, with a clear focus on operating reliability, productivity, cost discipline, supply-chain resilience and cash generation."

"As we finish 2026 and prepare for 2027, the next phase of One Tredegar is about turning organizational change into measurable results. In addition to simplifying our organization and driving accountability, we are positioning both of our businesses to capitalize on more strategic applications and larger customer opportunities focusing capital on areas where we believe we can earn attractive returns and build durable competitive positions. That includes improving Bonnell's operations performance, driving costs down, growing TSLOTS TM and developing higher-value applications in Films. We remain on track to begin realizing benefits from One Tredegar in the first quarter of 2027, and our focus now is execution: improving profitability, generating cash and investing behind the opportunities that can create long-term shareholder value."
