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.

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. We will do so though our investments and focus on sustainable solutions for high-growth markets, including healthcare, consumer, packaging and composites/5G.

Since 2013, the executive leadership selects 16–18 high per forming, high potential associates each year to par ticipate in the NextGen leadership development program. Such lists include REACH Substances of Ver y High Concern (SVHC) candidate list, U.S. Polymeric, high molecular weight fluoropolymers are too large to cross biological membranes.

Furthermore, designers, quality, and regulatory specialists face new compliance challenges as regulations such as the In Vitro Diagnostics Regulation (IVDR) EU2017/746 are tightened and impact of reclassifications come into force.

These include high-temperature, engineering and recycled polymers. Customers are guided through a color development process at the earliest stages of their product development to establish high-impact colors for their brands, helping accelerate time to market. Impact modifiers, scratch resistance, and antioxidant additives are just a few examples.
