Forward-Looking Statements: This press release contains forward-looking statements. All statements that address expectations or projections about the
future, including with respect to the planned leadership transition and expectations for future performance, growth and value creation for stockholders, are forward-looking statements. These statements are not guarantees of future performance and
are subject to risks, uncertainties, potentially inaccurate assumptions, and other factors, some of which are beyond our control and difficult to predict. If known or unknown risks materialize, or should underlying assumptions prove inaccurate, our
actual results could differ materially
from past results and from those expressed or implied by forward-looking statements. Important factors that could cause our results to differ materially from those expressed or implied in the
forward-looking statements include, but are not limited to: the inherent uncertainty of management transitions and the ability of the Company to successfully execute its planned leadership transition; industry capacity utilization and competition
from other specialty chemical companies; safety, health and environmental requirements and related constraints imposed on our business; regulatory and financial risks related to climate change developments; volatility in the price and availability
of energy and raw materials; negative or uncertain worldwide or regional economic conditions and market opportunities, including from trade relations, global health matters or geo-political conflicts; failure

interest rates, tax rates, currency exchange controls, tariffs and fluctuations in foreign currency rates; and other risks and uncertainties described in the reports we file with the Securities and Exchange Commission (“SEC”). These
