In this proxy statement, statements that are not reported financial results or other historical information are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. You can identify these statements by the fact that they do not relate strictly to historic or current facts. 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. In particular, these 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 global 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;

•changes to foreign trade policy, including new or increased tariffs and changing import/export regulations;

•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, cybersecurity breaches and cyberattacks;

•our ability to service our indebtedness and restrictions on our current and future operations due to our indebtedness;

•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;

•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, 2025 under Item 1A, “Risk Factors.”

We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. Investors should bear this in mind as they consider forward-looking statements. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by law. You are advised, however, to consult any further disclosures we make on related subjects in our reports on Forms 10-Q, 8-K and 10-K filed with the Securities and Exchange Commission. You should understand that it is not possible to predict or identify all risk factors. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.
