THERMOGRAVIMETRIC ANALYSIS REDUCED REGULATORY RISK With the increasing use of rPET, accumulation of AA scavengers can become an issue, particularly with ATA-based products, where there is a high risk of exceeding the regulatory migration limit. CHOOSE COLORMATRIX AANCHOR FOR SUSTAINABLE AND HIGH-QUALITY PET PACKAGING ColorMatrix AAnchor is an innovative solution for the polymer industry, offering a comprehensive solution to enhance the recyclability, quality, and regulatory compliance of PET packaging. By incorporating ColorMatrix AAnchor, brands are supported to achieve their sustainability goals, reduce environmental impact, and deliver superior products to consumers.

Impact on cost of sales Impact on operating income Impact on income before income taxes

The company noted that GAAP EPS includes special items (Attachment 3), which impacted EPS in both periods and were primarily associated with acquisition-related and restructuring costs. This is a direct result of the investments we have made to transform our portfolio to one that is more specialized and focused on high growth end markets with sustainable solutions,” said Robert M. Patterson added, “We are an asset-light, high-touch business that generates very high free cash flow conversion.

For 10 years, we have been building our advanced composites platform by focusing on high-performance materials for applications where failure is not an option. Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: the time required to consummate the acquisition of the Dyneema business; the satisfaction or waiver of conditions in the purchase agreement; completion of the consultation process with the relevant Dutch works council; the ability to obtain required regulatory or other third-party approvals and consents and otherwise consummate the proposed acquisition of the Dyneema business; our ability to achieve the strategic and other objectives relating to the proposed acquisition of the Dyneema business and possible sale of the distribution business; disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; the current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows; changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; fluctuations in raw material prices, quality and supply, and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; an inability to raise or sustain prices for products or services; information systems failures and cyberattacks; and other factors affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.

Unless otherwise stated, Operating Income, EBITDA and EPS figures included in this presentation are adjusted to exclude the impact of special items as defined in our quarterly earnings releases. Investing in Innovation — Specialty companies invest to grow, so we ensure our resources are concentrated on material science for high-growth end markets, poised for value creation in the long term. Being a Great Place to Work — We listen to feedback from our associates then take action in building our high-performance culture and being a global employer of choice.
