They use words such as "will," “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe” and other words and terms of similar meaning in connection with any discussion of future operating or financial condition, performance and/or sales. items, include statements relating to future actions; prospective changes in raw material costs, product pricing or product demand; future performance; estimated capital expenditures; results of current and anticipated market conditions and market strategies; sales efforts; expenses; the outcome of contingencies such as legal proceedings and environmental liabilities; and financial results. Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: • 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; • Disruptions or inefficiencies in our supply chain, logistics, or operations; • Changes in laws and regulations in jurisdictions where we conduct business, including with respect to plastics and climate change; • Fluctuations in raw material prices, quality and supply, and in energy prices and supply; • Demand for our products and services; • 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; • Our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends; • Information systems failures and cyberattacks; • Amounts for cash and non-cash charges related to restructuring plans that may differ from original estimates, including because of timing changes associated with the underlying actions; • Our ability to achieve strategic objectives and successfully integrate acquisitions, including the implementation of a cloud-based enterprise resource planning system, S/4HANA; • Other factors affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates, changes in the rate of inflation, geopolitical conflicts and any recessionary conditions; and • Other factors described in our Annual Report on Form 10-K for the year ended December 31, 2023, under Item 1A, “Risk Factors.” This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, restructuring costs, environmental remediation costs, acquisition-related costs, and other non-routine costs.

One of the most commonly cited advantages of TPEs is the ability to produce products via high-volume injection molding, which is an extremely cost-effective process.
