Forward-looking Statements and Risk Factor Summary

This Annual Report on Form 10-K (“Form 10-K”) includes “forward-looking statements” that express our opinions, expectations, beliefs, plans, objectives, assumptions or projections regarding future events or future results. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should” and similar expressions are intended to identify these forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short- and long-term business operations and objectives, and financial needs. Examples of forward-looking statements include, but are not limited to, statements we make regarding demand trends, global economic effects on our operations and financial results and our liquidity, and our belief that our current level of operations, cash and cash equivalents, cash flow from operations and borrowings under our credit facilities and other lines of credit will provide us adequate cash to fund the working capital, capital expenditure, debt service and other requirements for our business for at least the next twelve months.

These forward-looking statements are subject to a number of risks, uncertainties and assumptions. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed herein may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

Some of the key factors that could cause actual results to differ from our expectations include the following risks related to our business:

•as a global business, we are exposed to local business risks in different countries;

•we are affected by general economic conditions and economic downturns;

•exchange rate fluctuations could adversely affect our financial condition, results of operations and cash flows;

•our international operations require us to comply with anti-corruption laws, trade and export controls and regulations of the U.S. government and various international jurisdictions in which we do business;

•alternative technology or other changes in our customers’ products may reduce or eliminate the need for certain of our products;

•our new product development and research and development efforts may not succeed and our competitors may develop more effective or successful products;

•our substantial level of indebtedness could adversely affect our financial condition;

•if we are unable to manage the current and future inflationary environment and to pass on increases in raw material prices, including natural gas, or labor costs to our customers or to retain or replace our key suppliers, our results of operations and cash flows may be negatively affected;

•we face substantial competition in the industries in which we operate;

•we are subject to the risk of loss resulting from non-payment or non-performance by our customers;

•we rely on a limited number of customers for a meaningful portion of our business;

•multi-year customer contracts in our Ecoservices segment are subject to potential early termination and such contracts may not be renewed at the end of their respective terms;

•our quarterly results of operations are subject to fluctuations because demand for some of our products is seasonal;

•our growth projects may result in significant expenditures before generating revenues, if any, which may materially and adversely affect our ability to implement our business strategy;

•we may be liable to damages based on product liability claims brought against us or our customers for costs associated with recalls of our or our customers’ products;

•we are subject to extensive environmental, health and safety regulations and face various risks associated with potential non-compliance or releases of hazardous materials;

•existing and proposed regulations to address climate change by limiting greenhouse gas emissions may cause us to incur significant additional operating and capital expenses and may impact our business and results of operations;

•production and distribution of our products could be disrupted for a variety of reasons, including as a result of supply chain constraints, and such disruptions could expose us to significant losses or liabilities;

•the insurance that we maintain may not fully cover all potential exposures;

•we could be subject to damages based on claims brought against us by our customers or lose customers as a result of the failure of our products to meet certain quality specifications;

•our failure to protect our intellectual property and infringement on the intellectual property rights of third parties;

•disruption, failure or cybersecurity breaches affecting or targeting computers and infrastructure used by us or our business partners may adversely impact our business and operations; and

•the other risks and uncertainties discussed in “Item 1A—Risk Factors.”
